From all I've read, I'm inclined to say some of the difference (if not all of it) is Gen2 vs Gen3.

Gen2 x8 = Gen3 x4. If it is a pcie bus speed limitation then replacing Windows by Linux should help.

A given x16 slot may not be communicating at x16 (and it may be different versions of PCIe which move data at different speeds). For example, if you use one GPU, you'll probably get x16 speed. If you use two GPUs (and depending on the motherboard) a less expensive mother board may run each x8 or at x16 and x8 or .... depending on the total number of lanes supported. Check the detailed specifications of each motherboard.

Everything on that sheet is estimated PPD based on an entire day of folding a specific WU (which will never happen in real world usage).

Okay. Well, that being said, I still get pretty high PPD on one of my 1070. Is it unrealistic to assume the other 4 are able to output that much?

I've seen my 1070 post over 800k PPD in HFM when running certain projects, however its average PPD is just over 600k PPD. You probably have 1 gpu that is getting a fairly steady stream of high scoring WU, at some point it will drop back to its usual range, for now enjoy the additional points.

PCIe 2.0 x16 gives the same performance as PCIe 3.0 x8 and there is usually only 1 or 2 seconds per frame between 2.0 x16 and 3.0 x16. Where you start to see the performance drop is PCIe2.0 x8 or lower

Which is exactly what I said, no?

So, it's been a while since I posted here, but I thought it may be time for an update. In folding for Curecoin/Foldingcoin I made enough BTC (~$2,500 in 3 months) to justify a purchase of a new folding rig. Since my last post I've replaced one of my 1070 with a 1080 Ti and added another 1080 Ti to my CMD machine (I found out my motherboard actually supports a third PCIe device @ 3.0 x4).

So I'm now up to roughly ~5.3M PPD on my current 3 systems and the new system should eventually pull in another 4.4 to 4.8M PPD. I went with a system that supports 4 PCIe 3.0 @ x8. Out of the gate I'll have one MSI 1080 Ti FE and a Aorus 1080 Ti. I'll eventually fill the other two slots with a 1080 Ti once I mine more CURE/FLDC. All in all I hope to be really close to 10M PPD in the next 30 days.

Thanks for all of your assistance in helping me understand PCIe speeds.

We are a support site for Folding@home but if you need Curecoin/Foldingcoin support you'll have to visit their website.

That sounds like a nice system.

I'm aware.

and thank you!

So what's in the [email protected] slot??? That may be marginally good enough for a 1070. What's in the rig that you're expecting 4.4-4.8 MPPD???
What MB & CPU are you using??? Take a look at this one: https://www.newegg.com/Product/Product. ... 6BM56X8513
You can run it x16x16x8 or x8x8x16x8 @ 3.0. Do you know if [email protected] is fast enough for a 1080 Ti?

Huh That sure seems like an off-the-wall comment.

It's a simple statement of a forum policy.

I think he was responding to the fact that it seemed to "come from out of nowhere", as no one was seeking help/support for either coin.

I'm able to pull 1.2M PPD from a 1080 Ti card on 3.0 x8. The new rig will have 4 1080 Ti, so I estimate total PPD output between 4.4M to 4.8M. Right now I have a 1070 in the 2.0 x4. This will change once I get my new build ready.

I'm using an ASRock x99 WS and an Intel 5930k for the 4 1080 Ti build.

Is there any chance of AMD becoming a contender for folding with the upcoming new release of OpenMM ?
I read that the soon-to-be-relased Core 22 will use CUDA on Nvidia cards and will offer 20% improvement in performance over Core 21.
Any beta tester here to give us a hint?
