Folding Forum

Well, the laptop will be mainly used as a bridge to control the GPU. The one that's really folding is the GPU, while the laptop just merely sends the information to and back from the ExpressCard slot (to PCIE). So I presume it won't be using that much power, since the GPU is powered by an external p...

I think vram overclocking is easier than GPU overclocking. The EVGA app has a monitor that shows when throttling start. On my GT and GTX cards, the overclock instability usually results in an immediate drop in performance, unlike the GPU which starts throttling before crashing, and depends on card h...

Yes it won't work on battery, as the expresscard slot doesn't provide enough power, which is why you need an extra power supply. It's not really "on the go", but if you go to a public library, or a place with power, you can plug laptop and graphics card in, and leave it folding, while brow...

Best thing I found so far, is buy an old Laptop, like eg a Thinkpad or some 2004 Vaio, with an express card slot. I found several older dual core models for under $50 on ebay. It appears there are Express Card to full size PCIE (1x speed) slots for sale for $50. All you need then is a $15 external 1...

Well, that depends. Most of them don't install well. A good hundred that is. But I tried Sparky Linux, Puppy Linux, Tiny Core Linux, just don't install anything at all. I had issues with Fedora, so I didn't even get to install it. Many say it's an unstable version of Redhat. I tried Redhat and FreeB...

Latency is directly connected to RAM speed. Latency always stays the same, even if latency numbers increase, the overall latency is exactly the same using the same ram (only when you increase latency, but leave ram speed the same does latency increase). Eg: when you're running 1333Mhz RAM with CAS l...

Yes. I use EVGA s tool. Basically overclock while folding, at the cost of a few lost WUs while doing the process. Takes about 2 hours to set up all 3 cards, then implement a safety margin. . The HW monitor clearly shows when the CPU starts throttling, or even when CPU speeds become unstable. On my M...

Seeing that a GTX 1050 runs fine on a PCIE 1x slot at nearly full PPDs, I don't think the PCIE bus on older computers are a limitation. At least, if it's running 4x even a GTX 2070 will probably not be limited by it. Just as long as your CPU can feed it with enough data. Running my 1060 + 1050 toget...

Not sure how it runs on other machines, but even on high, my Xeon switches just nicely between programs. Then again, I have 10 cores, 20 threads. The majority of users now are GPU folding on modern hardware. That's where FAH gets most of their work done with. I think FAH should target that audience....

what version of Linux are you running? 32 or 64 bit?
I know some versions are supported, but the majority of Linux distributions aren't.

I'm currently running the GTX 1050 OC in a PCIE 1x 2.0 slot, and I see less bandwidth usage than with the GT 1030 (possibly due to the board auto switching between 1. v1.1 and 1x v2.0). The GT 1030 had 29% PCIE traffic, the 1050 has a mere 8%. Though slightly overclocked, the 1050 hovers around the ...

I'm not asking support for other linux variants.
I'm merely trying them out, see what I like about them,and which one works best with FAH.

Anyone has any experience with overclocking graphics cards on FAH? My GPUs can be overclocked between 80-200Mhz safely, which theoretically could account for about 5-10% extra performance, or 5-10% PPD + bonus points in the likes of 15-20% PPDs. But the GDDR memory can be overclocked between 600 to ...

Does it work on WIndows?

I personally put the fastest cards in the full 16x slots. I think a 1x slot can handle about 100k PPD in Windows, but supposedly more in Linux. It wouldn't surprise me if a 2070 is too much for a 4x slot in WIndows. If it's only 200-300k PPD, I don't think Linux will help. I wished there were some r...
