  1. 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.

  2.  

    God no, don't use the calculator, it's bad. The calculator doesn't calculate anything it's simply a bunch of stolen profiles...

    I recommend spending a day or two on tweaking, 1)put timings ridiculously high like 20-20-20-20-42-64 and find the highest frequency that works, with this setup I'd probably stop at 3800 and then tweak the timings and test stability, change 1-2 timings between runs that way you will know what works and what doesn't, I should add a reminder that there are formulas for many timings and you should visit DDR4 OCing guide from integral, I find that it's the most complete and reliable guide and comes from somebody who actually knows what's what: https://github.com/integralfx/MemTestHelper/blob/master/DDR4%20OC%20Guide.md

     

    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.

  3.  

    Would be interesting to see a memory bench of the mixed modules running vs a matched kit at the same speed and timings to see what kind of impact you are looking at.

     

    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!

  4. 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.

  5. Oh wow the ideal specs are pretty surprising. Never seen 32gb in a recommended spec sheet for any piece of software or game before.

     

    I know the dev team for this has been working hard to get near GTA levels of detail and depth to their environments. Going to make for one heck of a game when it gets released.

     

    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.

  6. 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

    If you are folding on your CPU, the ratio of WU-points will be lower than GPU folding. The reason for this is twofold:

    • Current CPU WUs are fairly small with a low TPF (time per frame) so they will complete quickly
    • Much of protein folding can be highly parallelized, so with an optimized GPU application, GPUs are able to do more work in a shorter amount of time than CPUs

    Additionally, faster GPUs and CPUs will see more points per WU. This is because of QRB (quick return bonus) which awards more points the faster that the work is turned around from server-client-server. With the newer CPU WUs, it is not nearly as big of a divide as it was a few years ago before the newer a7 tasks were released.

     

    This makes perfect sense. Thanks!

  8. Manual 4.3 OC here on my 3970X, but my CPU only gets a short break once every few weeks when I have to reboot for some updates. :D

    For my situation where the CPU is always at a minimum of 90% load, the overshoot/undershoot voltage swings with auto-boost and PBO were never really stable.

     

    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.

  9. So it looks like I am having a much better success at 4.3Ghz on the 3950X when folding. Will get it stable folding at the lowers Vcore I can and then run some other benches to make sure it is rock solid, then I can safely commit the CPU to the cause to, woop !

     

    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!

  10. Okay so the big thing I will suggest is manually splitting your CPU into 2 slots: 1 slot with 16 threads, and 1 slot with 6 threads. This would reserve a couple threads for your GPU.

     

    Also, you may want to add the flag "next-unit-percentage" with a value of "100" for all of your slots. It seems to make grabbing WUs more reliable these days, espeially with the WU drought we've been experiencing.

     

    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

  11.  

    Hey and welcome!

     

    Would you show us a screenshot of your folding client configuration? Since you have that many cores, you may need to optimize the CPU slots a bit.

     

    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.

  12. 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.
