Awesome that you've joined EHW! I just downloaded 1.7.1 and playing with/comparing timings from previous version. Updated interface is great. Not sure if you can answer, but I did have a question about 4 DIMMS. Regardless of import/manual, and other DRAM PCB revisions, I see Gear Down mode is always disabled now when calculating FAST at 3600 or 3733. (3733 had it enabled in 1.7.0) Particularly: ZEN 2, Samsung B-die, 3600 or 3733, DIMM Modules (4), X570, Calculate FAST Comparing to your 1.7.0 calculator, 3733 Frequency had it Enabled with 99% of the same timings. Any idea if 1.7.1 having it as Disabled is an oversight? I was under the impression it was almost impossible to run Gear Down mode Disabled above 3600 at cas 14 with 4 sticks. Edit: When I import XMP, I do get the CAS 14 timings with a Memory Chip Quality 100%. I have the G.Skill 3600 Cas 15 chips.

The case arrived a couple of days ago! Will hopefully find some time soon to throw a build together with it. I have a 2 month old so will need to sneak in parts between feedings/sleepings, lol. Are there rules to upload jpg's here? I tried uploading a jpg attachment but wouldn't let me. Guess I would need a certain number of posts?

Wow great reference. Thanks! Taking a look now. I don't know if my chip can hit 1900 FCLK 24/7 stable, I'd like to keep it at a 1:1 ratio. I may try 1900 FCLK and 3800 and start at high cas like you said.

Just wanted to follow up with the thread... I got my 2nd kit of F4-3600C15D-16GTZ I'd like to share what I did for Testing Purposes: 1) I pulled my original set of memory and replaced it with the new set. Same timings - 3733 Cas 14. Passed 60+ minutes with MemBench no issue. 2) I threw all 4 sticks in there and re-loaded Memory Defaults (2133, no idea what CAS or Voltage, but fully stock) Passed 60+ minutes with no issues. Here's the fun part, I started tweaking now... 3) I ran a DRAM Calc for 4 sticks at 3600. Plugged everything into the BIOS. Computer booted, but got errors in less than 10 seconds in Membench. Spent a couple of hours trying to adjust Timings, Voltages, you name it. Nothing worked. I then did some Googling and apparently there's NO way on my motherboard you can run four sticks at 3600+ with Gear Down mode disabled (daisiy chain topology). Unfortunately the calculator had it Disabled. I enabled it and it was good. Not satisfied at this point due to knowing there's a bit more potential. 4) I switched the DRAM Calc to 4 sticks at 3733. It now has Gear Down mode enabled with nice tight timings. Plugged everything in, and went to work. In the end, Passed for 240 minutes with 4 sticks at 3733 Cas 14 @ 1.48v. Heat isn't an issue luckily because I have a nice G.skill RAM cooler. Even after the 4 hours, Max memory temp is 35c. I probably don't need the cooler (Would have probably been around 45c) but it doesn't hurt to have!

Awesome! I agree with you guy. I just wanted a second opinion When I get my 2nd kit, I will take my first kit out and Membench it to make sure it's stable at the clocks I want, then I'll throw all four sticks in and tweak timings a bit. Thank you ?

I know memory manufacturers don't advise to do this, but what's the general take on adding an additional memory kit of exact same kind to a system? I have two 8 gig sticks (16GB worth of RAM) but want to add another two 8 Gig sticks. My thought process would be to buy the memory, take the original memory out, put new memory in, and test it for errors and stability. Then I would add the other two (all 4 dimms in at this point) and re-adjust clocks, timings, and voltages. Is this a bad idea? I'd just hate to eat the cost of the two 8 gig sticks I currently have (good rated b-die memory) and go either go two 16GB kit or four 8GB kit.

That's what caught my eye too. My gaming rig only has 16GB. Makes me wonder if It's time in general to upgrade to 32GB or if the 32GB "number" is going to be overstated. I can see a lot of the textures being put into VRAM.

I'm ecstatic to have won the InWin case. Congrats to all the winners! Thank you for the giveaway!

My last purchase is lame but here it goes... DELL/Intel I350-T4 PCI-Express PCI-E Four RJ45 Gigabit Ports Server Adapter NIC (can't upload photos yet unfortunately) I'm going to attempt to make my own high powered pfSense firewall out of some older PC parts. This is pretty much all I needed. Not sure how it's going to go but I will let you guys know... lol

I think most my WU's came from my 3900x. Probably half as much from my 1080 Ti.

This makes perfect sense. Thanks!

That makes sense the way you're using the chip then. Yeah, as far as I'm concerned, PBO is still kind of broken anyhow. I actually got lower scores with PBO enabled, lol.

If you're thinking of lowering vcore, or even figuring out how it works... I would take a look at this review: https://www.gamersnexus.net/guides/3...ffset-override You can actually lower vCore all you want, even go as low as 1v probably. Nothing will crash, however you will actually sacrifice major performance. These new chips work very differently than 1000 and 2000 series Ryzen chips. You will literally have to run something line Cinebench for each voltage increment until you know you haven't lost performance. I've had my 3900x since last August and read/watched tons of videos regarding how it works, including dos and donts. The general consensus is don't even bother trying to manually OC it for 24/7 use. The performance gain is minimal if any, and you lose the single core / multi-core higher boost. I suppose if If you're onlyyyy doing Folding at Home and you're on a custom loop and always maximizing the use of all threads, then maybe you could play around with manual/static OC But it's going to be a pain... Edit: I should have added, If you keep everything stock (minus the RAM of of course, that always has to be manually adjusted), the CPU will adjust frequency based on CPU temperature. AMD's algorithm works well unless you're running liquid nitrogen. For instance, I've gotten higher Cinebench scores in the Winter time, and slightly lower scores in the Summer time (all due to ambient temperatures). Good luck!

100% True, other than the fact everyone's either working from home, or not working right now. lol

? That's actually another question I had. Probably a simple answer. Is there a correlation between points and WU's? I noticed I have more WU's (22) than people with more points than me.

Thank you!! Does this look right? https://ibb.co/D1TQrZS I now have three total slots. One with 16 threads, one with 6 threads, and one for my GPU

Much appreciated. This is my first time using F@H in over 10 years so I'm sure my config can be optimized. Currently I've left everything at default with the exception of Power Consumption set to Full. I tried attaching three JPG's but it's saying blocked by file scanner, so I'm sharing via three image links. https://ibb.co/xMB8S6V https://ibb.co/SK3m629 https://ibb.co/dc6m7VM Thank you!

Hi Guys! I'm new here, but will be assisting the ExtremeHW team for folding at home for the Covid 19 Fight I've already started folding last night. I am using all cores on my AMD Ryzen 3900x as well as my GeForce 1080 Ti with a voltage limit of .875 (when folding, equivalent to about 65% card power usage) I do have a recommendation for those on Ryzen/Threadripper 3rd gen. Use 1usmus DRAM Calculator. Not only can it help assist you with Memory Timings/Voltages, but it also has a MEMBench /memtest built in. Under the MEMbench tab I recommend Memtest mode with a Task Scope of at least 200%. Depending on your memory speed/timings, I would let it run at least 30-40 minutes. If there are any issues with your settings/voltages, it will stop on 1st error by default.
