Folding Forum

Hi, Looks like you have some drivers problem with Thunderblot bridge(s), but you can try to tweak with folding_slots tab when configuring client. In any case even if eGPU will fold - Thunderbolt may be limiting for new core_22 WUs - which load up 40-50% of 8 lanes PCIe 3.0 bandwidth. Thunderbolt bri...

Hi, In addition to "No WUs for this configuration" and "WorkServer connection failed on port 8080 trying 80" between WUs - there is another problem for last or so 10 days. Some core_22 WUs crunched without any errors to 100%, then results send, then server shows resond WORK_ACK (...

Suspecting that GCN/Navi cards auto underclocked by drivers when fold low atom-count projects.
Please try to disable ULPS as written here https://community.amd.com/thread/176003 and compare PPD with ULPS enabled vs disabled for that small projects with lowest PPD.

Another cause of low PPD and underutilization with low atom-count projects may be ULPS enabled, everyone with Vega/5700XT/R-VII - can try to disable this thing and after rebooti see to PPD with low atom-count projects:

You can try to update both BIOS and OS to later kernel versions, Zen2 at moment of launch had some problems with Linux, which were fixed with later bios updates and with next Linux versions. As I can remember - Linux kernel 5.0 was pre-Zen2.

The Radeon VIIs really seem to like the 11738 and 11739 WUs, but it should be noted that (based on my results) the 11737 has disappointing PPD (~780,000) on the Radeon VII. Don't know any other card halving PPD on small atom-count projects, so in this case R-VII may be temperature limited, because ...

I tried WINE and it wouldn't work with my s/w You can try Crossover for Linux, based on Wine but with some tunings for suppirted applications, and more user friendly; free trial available for download from their site. Drivers do not influence FAH folding performance But they do, at least for Pascal...

AM4 200-240GE Athlons have only 4 PCIe lanes to 1st x16 PCIe slot, some Asus boards had bioses with unlocked 8 PCIe lanes for Ahlons (but they may be closed now, should check), but again all lanes routed only to 1st x16 PCIe slot without bifurcation to 2nd x16 slot. All onchip iGPUs are weaker in co...

Same problem. Last was PRCG is 14167 (4, 14, 191).
Both with old 7.4.16 and reinstalled 7.5.1 clients, AppData folder was cleaned before 7.5.1 reinstallation.

I have Strix GTX 1070 @ 2000 MHz @ Linux Mint. At Linux FahBench it draws 130 ns/day, but card's PPD nowhere near to other cards with more CUDA cores and with ~130 ns/day and only 800k @ 2000 MHz. Keeping in mind that 2060 have same 1920 CUDA cores as 1070 but with power draw at stock boost 1680 MHz...

Yep, I didn't see 4 WUs in stats, team also miss some WUs.

Can anyone explain why Linux is so much faster?# It's all about GPU utilization under OpenCL loads. I have an old s1366 system - 6 core Xeon @ 3800 MHz, PCIe 2.0 x16 slots and GTX 1070 clocked 2050 MHz. With Windows 10 GPU utilization most of the time was 82-86%, nearly the same with any of new dri...

it allows GTX1070 @ 2.1GHz with p9431 folding load up to 82% while up to 85% without any heavy CPU occupation You need to try Linux Mint with that how-to from tguskill (great thanks to him) from overclockers.ru board. I saw same low GPU utilization under Windows with PCIe 2.0 and about 96-97% GPU u...

I think that multi-GPU systems PPD degradation is because of copies of fahcore21.exe walking between CPU cores. In rig with 4 GPUs you have 4 fahcore21.exe and all 4 doing a chinese firedrill all the way. One of possible solutions to increase PPD in multi GPU rigs with PCIe 3.0 motherboards is Proce...

Hi Second day some of my finished and sended WU missed from Stanford (and any) stats. I don't have yesterday's logs, but visually around 100-150k ppd from GTX 1070 was lost, without any broken WUs with little points (I look here this http://folding.extremeoverclocking.com/user_summary.php?s=&u=7...
