Nvidia Pascal GPU cards???

[Torin3]

@Nebulae or Torin3: I'm interested in GTX 1080 pcie bus usage. Can you check the GPU pcie bus usage while folding with e.g. msi afterburner?

Running between 32% and 42%, fairly even spread between the two end.

This is on a 9704 WU, getting 745K ppd.

9160 WU is between 38% and 40%. Very little variation. 800K ppd.

Torin3: What speed is your PCIe bus?

[Torin3]

It is a x16 3.0 slot running at x16 3.0 according to GPU-Z

More FahBench 1.2 explicit results in ns/day
GTX 1080 OC _ 113 for 700$
GTX 1070 OC _ 103 for 450$
GTX Titan X _ _ 84

I think GTX 1070 OC will be the new dollar per PPD King and all at 200 Watt.

I'm testing right now on a EVGA GTX1080 FE with EK-Waterblock installed.

However the load is at only 89%. I don't know what I have to do to get it to 100%....

Max GPU load shown on my PC was 94% and this is really heavy on GPU.
What CPU do you have? Maybe you can pause CPU folding and only fold on GPU to see if this makes a difference in GPU load % ?
If it does then you need to reduce your CPU slot max core count to an even number because GPU needs a CPU core to support it.

You probably can't.

Data must be transferred between main RAM and the GPU before the shaders can work on it. A certain amount of time is spent transferring data, some of which may be overlapped with processing and some of which cannot. As you increase the speed of the GPU without increasing the speed of the PCIe bus, the percentage of non-overlapped time increases. and the GPU isn't as busy because it's finishing what it can to faster.

It folded just one WU with the CPU, because it automatically launched one. So I didn't have a choice and let it finish. I have a Core i7-4930k @ 4.5 GHz supported by DDR3-2333 MHz, and now it's doing absolutely nothing while folding, yet my GPU load doesn't surpass 89%...
I have the BCLK on my motherboard set to 125 MHz as well. Too bad, I thought I had the ideal setup to fold even faster. Seems I just hit the limitations.

On modern systems, PCIe data transfers are not limited by a lack of CPU resources. The bus speed has it's own limitations.

With a system like that, you should be folding with your CPU, too.

[foldy]

Too bad, I thought I had the ideal setup to fold even faster. Seems I just hit the limitations.

It also depends which FahCore and work unit you are currently running.
e.g. FahCore_21 with 13xxx work unit really has high usage like 95% while other cores or work units can have below 90%.

p11430 has a relatively low number of atoms compared to other FahCore_21 projects so it may be harder to evenly allocate work across the entire GPU. You can see the atom counts on psummary.

Short feedback from a mixed running of a new 1070, FAH Client 7.4.4. and BOINC, Win8.1, Eco mode by Gigabyte ´Etreme Gaming´ tool. [No overclocking, no default setting, only eco clock so far.]

Recognition was done fast, folding started at once, finished some x18/x21 workunits, everything fine.

No more FAHMon support, tried it, but sorry, no detailed PPD information (made screenshots with ~510-530k PPD, 415k with the current P10489), it can be calculated with the period time from the log.

You're living in another century, FAHMon support stopped a long time ago (it never supported v7 client). Use HFM instead : viewtopic.php?p=285846#p285846
