  1. Thanks for getting back to me! The system is built and OPNsense is installed on a little ITX 9900K. I have an Intel 10g NIC for the device too. I think it's total overkill but hopefully, it should run for ages and not give me any problems. I am set up with Comcast DSL at my house. It's rated for about 600Mbps down and 120Mbps up. It's not great but it's what I can get in my area and the price is nice at $55 per month. I don't like the Comcast router/modem even though it's high-performance and free. It's WiFi6 and has never failed once, but it broadcasts the xfinitiywifi signal for all users to piggyback on my network, which is the real reason I want to turn it into a bridge. As for my network requirements, it's pretty simple. I don't need a VPN or anything like that. However, my work laptop is quite aggressive and talks to everything on my network. I was thinking about setting up a VLAN so my work laptop is completely isolated from my home network. I guess I would need to buy a managed switch for that?? Right now I setup a guest account on my WiFi and I connect my laptop to that. I think it's fairly well isolated but that laptop has fangs
  2. Hey Guys! I've used consumer-grade routers for the last 20 years and I'm just now diving into this madness I decided to go with OPNsense. It looks like they provide many more updates than pfSense. I built my first router but haven't given it internet yet. I'm going to put my Comcast modem/router combo in bridge mode and run this bad boy as the DHCP host. Any tips or advice?
  3. I'm drinking the Kool-Aid myself. My 3090 died playing Cyberpunk so I decided to pick up the A770 and check it out. Obviously it's not a contender for the top Nvidia cards, but it doesn't pretend to be either. I appreciate the value of this card right now but I really love that fact that it's getting noticeably faster every few weeks. I have big plans in store for overclocking and I just picked up a second A770 so I can brutalize one and let it ride the lightning
  4. The ARC card looks amazing for the price and it's just the start. I am excited about this GPU and I am looking to grab one as soon as it's available again. Anyone out there have one?
  5. Hey keyboard nuts! My wife is about to take a hammer to my current mechanical keyboard because of the late night typing. I need a recommendation of a silent mechanical keyboard, something similar or quieter than a rubber dome one. As for the budget I'd like to stay in the $75 range if possible...

  7. Hey Guys! I have been using my smartphone for review pictures, but I am continually fighting it and I want to try something new. I really don't know anything about cameras, but I want to try out a simple pint and shoot. I have been looking at cameras on eBay and I was just going to randomly grab something around the $100 price range, but thought it would be a good idea to reach out first. I was looking at the Sony DSC-W800, it seems like a good piece of hardware for the price. I am looking for something that takes amazing pictures (mostly macro), is easy to use even for a complete noob, and is also cheap AF....that's all ? Any help for this noob? Want to trade me a camera for some computer hardware?

  9. That's exactly right! I have also seen cards with damaged PLL, 5V, and 3.3V rails...all of those broken voltage regulators could be replaced with this device. It has lots of applications outside of extreme overclocking! Thank you! And yes...my wife would say the exact same thing...with a strong eye-roll tossed in for good measure
  10. Elmor recently started taking orders for the AMPLE 20A power card. It’s a simple little single-phase VRM that can be used to replace a broken VRM or simply overcome that pesky OCP/OVP. The most common potential usage would be for a GPU memory rail. However, with an output voltage from 1.0-3.4 V it could be used for many different applications. I obtained a test sample of this new device and I intend to put it to the ultimate test. I have an RX 580 GPU with a damaged memory voltage rail, but otherwise the GPU is in perfect condition. The plan is to solder on the AMPLE power card and observe the impact on the memory overclocking. I know what the card was capable of before the memory VRM died, so it’s the perfect test case for this little device. So follow along as I put this thing to the test and find out if it’s capable of delivering sufficient power to 8 GB of GDDR5. The AMPLE Device The device ships in an anti-static bag with the 6-pin connector added in as an accessory. This gives you the flexibility to power up the AMPLE from any qualifying voltage source you desire. Product Specification Output voltage adjustable 1.0-3.4 V using the on-board potentiometer (range can be increased by adding your own potentiometer) Nominal input voltage 12 V (functional from 4.5 V up to 16 V) Max output current 20 A (thermally limited). Active cooling may be required to achieve high output current. Efficiency at max output 91.5% (3.4 V, 20 A, 750 KHz) Switching frequency selectable between 300 KHz and 750 KHz OVP (+20%), OCP (24A) and OTP (Tj = 150*C) Output voltage can be monitored and adjusted using the EVC2 VMOD1-header Ships with a PCIE 6-pin power connector which can be soldered on by the user Switch 1 OFF = 750 KHz switching frequency Switch 1 ON = 300 KHz switching frequency Switch 2 OFF = PSM = Power Saving Mode, higher ripple but lower loss at low loads Switch 2 ON = CCM = Constant Conduction Mode. The PMIC is always regulating to the best of its ability, for the tightest possible voltage regulation. In some cases, for example with this project at 3.0V+, that will create a high loss in no-load or low-load situations. Source Credit: elmorlabs.com There is one switch on the device which acts as a mode selector. There are a total of 4 different combinations you can set, which change the output delivery settings. For controlling the voltage there are multiple different methods you can choose from. To make things simple, there is a potentiometer on the power card for direct control. For more advanced control, you have the ability to integrate the device with an EVC2 module using the vmod connection. Mounting the Power Card Before you just hastily solder on the AMPLE device, you should take the time to power it on and make sure it works. I would suggest powering it up and setting the desired voltage before you attempt to solder it on a GPU. The underside of the AMPLE has power and ground planes. In my particular case I won't need these connections so I decided to insulate them with a few layers of Kapton tape. This is an unnecessary step, but in my case there were a few components on the card which were extremely close to shorting on the AMPLE device. I chose to mount mine with 0.8 mm copper plate. I kept the plane-to-plane distance as short as possible. Furthermore, I always prefer to make my ground connections on the front of the card after where the main connection is. In the picture below you can see both ground connections come after the memory plan connection. In my testing this provides the best realized MHz whether it be core or memory external VRM replacement. Test Setup The overall goal is to compare stock PCB memory overclocking with AMPLE power memory overclocking. To make the test consistent, I will use the same load voltage for both test conditions. The test methodology is to overclock memory and record the passable frequency in Fire Strike GT1. I will start at 2280 MHz, increase +10 MHz until it becomes unstable PowerColor RX580 8GB Golden Sample Z490 test platform AMPLE VRM on memory rail Memory IC: Micron D9VVR 1625 MHz strap timings copied to 2000 MHz strap (Most efficient timings possible without diminishing returns on frequency) In order to get a realistic look at the voltage response of the device, I have placed voltage test points (TP1-3) at various distances away from the main inductor. During the load tests, I will also be conducting thermal tests of the mosfet heatsink. Ambient temperature for all tests around 24c The voltage read points are as follows: TP1 = AMPLE power voltage at C10 cap TP2 = GPU plane voltage at solder connection TP3 = Memory IC voltage at MLCC cap on back of card, at least 100mm distance from AMPLE Vout solder connection Test Results Voltage droop is the enemy of external VRM mods. It’s important to know exactly where the voltage droop occurs because it can narrow down the cause. The voltage test point results indicate that the droop is not caused by the solder connection. The voltage droop is present at the C10 capacitor so therefore it’s coming directly from the AMPLE VRM. This makes me happy because the solder connection is relatively perfect, but it’s mildly concerning to see the AMPLE being stressed under load. Regardless of any droop, the card was still able to pass FS GT1 test at the highest possible memory frequency. There is effectively no difference between the stock VRM and the AMPLE VRM for this test application. The temperature reached a peak at the end of GT2 and was still climbing. With the Fire Strike test, GT3 is CPU based so it had a cooldown period. The max temp of around 50c seems reasonable but further testing may be needed. Sustained loads of 1hr might show a different result. SW1 Test results proved inconclusive. Disregarding experimental error, there was effectively no difference in the realized MHz or voltage response. Conclusion Overall I am extremely pleased with this little device. It performed exceptionally well and the end result is that I was able to achieve the same overclocking performance as the stock PCB. The AMPLE single-phase power card has been validated for benchmarking purposes. In terms of the switch options, my expectation was that CCM mode with 750 KHz would be the optimal configuration. The switch test results showed that the various combinations didn't have any noticeable effect on realized Mhz or voltage response. The 10 mV voltage droop is a mild concern because it’s coming directly from the AMPLE, however, it did not affect the overall overclocking result. With a price tag of just $20,, it’s an absolute must-have tool for extreme overclockers. My RX580 is the perfect use case. The card was effectively dead and useless, but the mighty little AMPLE device brought it back to life and it still holds gold in TIme Spy. Even if the price was tripled, I would still recommend it because of its potential value. This was just my first test, stay tuned for more tests to come.
  11. Wow, really nice! This is a great tool and very useful, thank you! I am often testing different versions of W10 for benchmark efficiency, this makes it nice and easy to grab any one I want.
  12. Ok guys, anyone out there able to help me setup and optimize Threadripper 3970X? It looks like some people are getting it up to 1 million PPD...which seems like alot for a CPU?? I did a bit of googling and it seems there are some tweaks that need to happen to get the max out of this thing. I read some stuff about 'slot' settings for core/thread count but I am totally clueless. Also, can anyone give me a really quick summary of how this scales with overclocking? For instance, how much system memory does it use and what the score increase? Overclocking CPU? Mem? I've been in the professional XOC world for some years now but never touched folding until yesterday...I know nothing.
  13. Good catch, I let it munch last night then saw this a few minutes ago. I swapped teams and now it's working again
  14. I have never folded a day in my life, but I have a rig I can setup and try this out I might need some help from the folding pro's...
  15. All basic mode... 1920x1080 with 60Hz The bench automatically loaded in a window, which I have no clue what size that is. I did nothing but install and run on a dirty v1909 W10 install.
  16. Bone stock run with absolutely ZERO tweaks or OS optimizations.... This is just a simple 9900k on Z170 with XMP memory and a stock 2080Ti KP. It looks like the score is higher than it should be, bummer this bench is so inconstant.
  17. I am getting setup to play with this bench again. Looking forward to helping out with the testing and seeing if we can figure out the how it scales. My biggest complaint is that this bench cannot be run in offline mode, and requires a huge download.
  18. Oh that's really odd. I only did a quick run and I don't remember what my config was. I will have to play more and nail down how this bench works.
  19. A few things here. Firstly this bench is very inconstant in terms of run-to-run score. Run the bench 5 times and you will see a big variange. I saw a big gain from disabling SMT, so that's something you can try.
  20. I ran a quick one using RhreadRipper and stock card, so I am guessing the score sucks... We need more runs to compare to
  21. The madness begins! I am excited for the new platform and cant wait to start playing with it.
  22. It looks like the winner has been announced, congrats!
  23. My 2080Ti desperately needs that PSU for so it can be a dedicated GPU PSU for LN2 GPU sessions. If I win, I will certainly post pictures of it in use My contest submission 1.

  24. Welcome! As many of you know I have been spending lots of time modding GPU's for OCN team members and myself. After doing over 100 voltmods I have learned a few things and I want to share what I have learned here with you guys. Not much of this information is new, you can find quality information scattered everywhere around the web. My goal with this thread is to collate everything I have learned into one cohesive source. The goal of this thread is to provide general information universal to all GPU's. I will not be providing much information pertaining to specific GPU's. This document will be a work in progress. Basic GPU Volt Mods Section 1: Introduction If you are reading this then you likely don't need much of an introduction into overclocking, so I will skip the newb stuff. There are two main ways that the PWM controller can increase the voltage to the core. There is the feedback loop method (FB) and the sense method (+Vsen). In both cases the maximum PWM output voltage is set by an external resistor network. Lowering the resistance of the FB or +Sense pins, will in turn raise the maximum voltage of the of the PWM. In modern cards there will be different voltage and power states which can throttle down both the number of active phases and voltage. However, lowering the resistance of the external FB of +Sense resistor network sets the maximum output voltage during full load conditions. Section 2: Examining the GPU Step 1: Locate the PWM controller The first step is to identify the voltage controllers of the card. This can be really confusing at first but once you do enough of them, they will become easy to spot. In most cases the core and memory PWM controllers will be QFN package parts, but on older cards or low power cards they can be SOIC packaged parts (google those if you don't know the package names). The trick is that in most cases the PWM controller will be very close to the choke/driver it controls. Therefore, the first step is to identify the large inductors and you can be fairly certain that the PWM will be close by. Here we have a basic reference GTX480 as an example Step 2: Find the corresponding PWM datasheet After you have identified the target PWM controller, the next step is to find the datasheet that tell you the pin assignments. This is often the most difficult part to modding GPU's because many of the datasheets were never released or are still NDA. The now famous engineer TiN over at EVGA currently has compiled a database on his website xdevs, this is the best resource for finding unreleased or NDA datasheets. The datasheets he has made available to us are searchable via google. Step 3: Measure the resistance Once you have the datasheet then you should be able to easily locate the important pin that was mentioned earlier. You are looking for a pin marked "FB" or "+Sense" (sometimes called VSEN or VGPU). Here are a few examples of what you are looking for, they also happen to be hard to find datasheets There will be a marking on the IC and a marking on the datasheet IC so you can orient yourself. Once you have correctly located which pin you will be working with, take your measurement from the very first discrete part you see connected to the pin. You should never have to work with the pin itself, always work on the parts connected to the pin. In rare cases the pin you need will be underneath the PWM, but that is a problem for a different section of this guide. Working with the GTX480 example again, you can see it uses CHL8266 and the pin you want is VGPU (pin 4). In this particular case, I measured a resistance of 1.6 ohms. Write down this number because it is the most critical aspect to the voltmod. Section 3: Parts and Preparation Step 1: Choose a potentiometer value In step 3 of section 2, you figured out the stock feedback/sense resistance of the PWM you wish to control. There is a very simple formula you can use to determine the appropriate pot value. Simply multiply the FB resistance by 23 and then choose the next highest standard potentiometer value. Using the same GTX480 as an example, we measured 1.6 ohms for the core FB/Sense. In this case we take the stock resistance of 1.6 ohms x 23 = 38.8. Given that number, I know the next highest pot value will be 100Ω, so that is the part I will choose for the mod. Below, you will find a list of all the "typical" potentiometer values followed by the code that is printed on the pot itself. 100Ω (101) 200Ω (201) 500Ω (501) 1KΩ (102) 2KΩ (202) 5KΩ (502) 10KΩ (103) 20KΩ (203) 50KΩ (503) 100KΩ (104) 200KΩ (204) 500KΩ (504) Choosing the correct pot value is critical because this will determine the controllability of your mod. If you choose a pot that is too small (under 20x multiplication) then the new idle voltage will be much higher than normal. Conversely, if you choose a pot value that is too large (greater than 30x multiplication) then the mod will be difficult to control at higher voltage. In most cases, the simple formula of 20-25x will be correct. Step 2: Prepare the potentiometer Firstly, unscrew (counterclockwise) the potentiometer completely, this might take 10+ turns and in most cases you will here a little click when its fully unscrewed. You will need to trim the pot legs to decrease the possibility of shorts and mistakes. Below is an example of a perfectly prepared pot. You need to remove one leg completely and I suggest trimming the legs a bit. I like to add little disable switches to my pots. This allows me to easily enable or disable the mod completely. Using this method, you can run a card 100% stock and then easily enable the mods when you are ready to bench. There are several advantages to this method. If you wish to take this unnecessary step, simply trim the pot and the switch, bend the center leg of the switch, add a tiny dab of super glue, then solder the switch in place. I like to add nice long wires to my pots and use shrink tubing. Sometimes I will prepare a bunch of common sized pots so I have them ready when I sit down to do a bunch of mods. I use 28 gauge wire and 1/8" shrink tubing. Section 4: Putting It All together Now that you have your potentiometers all prepped, and you know the where the mod points are, its time to solder it all up. I like to use hot glue to affix the pots to the card itself. Once the glue dries then I test route the wire and cut them to the length I think I will need. In almost all scenarios, you should solder one lead of the potentiometer to ground. You can get ground from hundreds of locations on the card, but I like to use the 12v PCIe connector. If you prepare everything by tinning it with solder first, it will make the connection much stronger and it will make things easier for you in the end. Add solder to the solder point you have chosen on the GPU. Then I strip the wire (remove about 1/8) and tin the wire. The secret is to clip the exposed wire super short after you have tinned it. If you did the prep work correctly, you should be able to quickly and easily solder the wire to the mod location. If you want to add a nice finishing touch to your mod, then spend a few extra $$ and get voltage displays. I will cover them in the parts section later. The displays require a voltage source, I get +12v directly from the PCIe connector. Voltage display wiring: Red = +12v from PCIe Black = Ground from PCIe White = Voltage read point (choke or choke cap) Where you place the pots and displays is up to your own personal style. I have tried lots of different configurations myself and I definitely like the pots to be accessible from the back. Here is an example layout of pots and voltage displays. Section 5: Testing I have often been asked how to test the voltmods and unfortunately there is no generic answer or mathematical solution. Voltage scaling, voltage tolerance, and voltage limits are all factors that are unique to each card. I tried to come up with a generic % increase formula in the past but it really just doesn't work out, so instead I will give you some guidelines to work from. Core Over-Volt In most cards you will reach a point where scaling stops either because of the silicon or the temperature. There is no secret sauce to figuring out the correct voltage, it just takes time and patience. The best advice I can give is to start small and increase slowly to see what effect increased voltage has on the card. I typically don't push much more than +250mV for old cards and +150mV for newer cards (assuming very good cooling with temps under 60c). Again, each card is different and those numbers might not make sense so keep that in mind. Memory Over-Volt Most cards just don't scale much with memory voltage. When I get a new card I start with +10mV and see if there is any scaling from that. If I see a scaling improvement, even a tiny margin, then I keep increasing and testing up to about +100mV. Heat could be a factor so keep that in mind. Memory voltage increase can help in other ways. When you are running LN2 with Samsung and other's, adding lots of memory voltage can stop the memory from having cold bug issues. I have not tried this myself but I have herd that sometimes it can take +500mV to generate enough heat so as to combat cold bugs.
