Re: RTX 4090 is getting 26M PPD

Even the very lesser cards sometimes will not reach power limits of the hardware. It's quite possible they might with more intensive assignments designed for more powerful series cards. I'm not sure how F@H will "scale" towards the newer high end cards, but I do feel your pain. Really sho...

Re: 4090 Power Plug and F@H

From what I read, the 4000 series results seem very similar to the 2000 series cards, Apparently the card is folding at ~80% of it's max rated TDP. So setting it to 70% means only capping about 10% of the power. If they operate similar to a 2000 series, I would recommend to cap the power even furthe...

Re: Banana pi

It's unlikely, but perhaps an Orange Pi 4 will work. It has 2x A72 cores, and 4x A53 cores.
No guarantees though

Re: Re-application of Thermal Paste for GPUs?

The GPU sometimes uses thermal paste. The memory modules most of the time use thermal pads. I saw a guy who CNC-ed a piece of copper to replace the pads, and used thermal paste, and saw a +20C thermal drop. For the rest of us, it's best to find the highest rated thermal pads, and reapply the thermal...

Re: 3950x LOW PPD

@Jim, it's not only folding that proves that the 3900 series is memory bandwidth limited to roughly 24-28 cores. Other programs also have indicated that there's an internal bottleneck (most likely RAM wise, or Infinity fabric wise). You can always try to flash your Bios, make sure you have thermal p...

Re: Raspberry Pi 4 CPU 50%

I believe it's an old issue;
FAH will first fold a small WU on few cores. Just let it finish. Once it finishes fine, it'll download WUs utilizing the remaining cores, so long your client can see the cores, and they are configured in the client to be used.

You don't need that. You can set the CPU core count in the Manager.

Re: How legit is uptodown folding@home? [Not legit]

Some things don't run on GPUs (including some of the folding projects, or could they all go on GPU?), so I guess Amperes have their uses. Most things don't run on AMpere CPUs at all! Folding doesn't work on it, boinc perhaps some projects might. But there's just not enough supply out there for scie...

Re: 3950x LOW PPD

I wouldn't pay too much attention to it. Some WUs run lower PPD scores on CPU.
Also, you need to wait at least before 5% of the WU is done, before reading results.
Third, the PPD scores only work when the CPU is folding 100% of the time, and doing nothing else.

Re: How legit is uptodown folding@home? [Not legit]

I cannot locate those on Ebay :-) What's the price? An older 80 core Ampere system goes from anywhere upwards from $2500. The server editions usually go several thousands of dollars more. While they are quite efficient, they're not as efficient as GPUs in terms of folding. They need to come out wit...

Re: Run two tasks per GPU?

The N3700 doesn't have that many lanes. It only has 4, I believe one is for SATA, one for network, 1 for USB, something like that. Only 1 is present at the only PCI Express slot. You don't need anything like v3 x4. I've got two 280X cards running maxed out on folding right now, sharing a v2 x1 slot...

Re: CPU Folding No Checkpoints?

We used to make a .bat file on the desktop to shut the pc down.
In it, you can shut down the client, put a wait cycle in it, and then shut down the system.

Re: Run two tasks per GPU?

Update - I was right in the first place. Two 280X cards CAN run shared on a single PCI-E v2 x1 lane, both going at full speed on Folding. The other CPU must have been too slow, which is odd as the usage was a fraction of a core to help each card. Maybe the delay for each bit of the CPU part of the ...

Re: why GPU dependancy ?

My understanding is, that certain instructions can only be done with the CPU. There's CPU folding (high accuracy, slow speed), and GPU folding (high performance, lower accuracy). And with lower accuracy, I mean 16 to 32 bit calculations. A modern GPU has thousands of of 16-32 bit shaders, that can c...
