I'm new and I have some GPU issue with FAH

Hello,
I'm new to FAH so please bear with me.
I installed FAH on both my PC (i3770k/GTX 295) and my Macbook Air (2011). CPU folding on the PC/Mac works great. However I have an issue with GPU folding [Edit:on my PC]. Both my GPUs got work assigned, no errors in the logs. The problem is that if I move the slider to Full OR wait for the FAH screensaver to kick in on Medium nothing seems to happen (besides the computer becoming unresponsive which is I guess OK given that GPUs can't prioritise). However:
- nothing seems to happen - the GPU work units stay at 0.00%...?
- When I switch back to Medium / exit the screensaver my computer remains unresponsive - it's like the GPUs are still processing even though the client states they're shut down and waiting for idle - I have to actually kill FAH altogether to get control of my PC back - is this normal? I tried reinstalling the client but nothing changed... I'm using the latest nVidia drivers 314.07, I believe.
Many thanks!
Updated with specs:
Computer Specs: CPU - 3770k, 8GB DDR3, 4cores + HT; GPU nVidia GTX 295 - drivers 317.04
Network Connection: Cable - NAT, no proxies
Operating System: Windows 8, all HFs and updates
Overclocked?: Was... given my troubles it's at stock
Stable?: Yes, memtest86, furmark, memtestcl, prime95...
Software: FAH 7.3.6, CPU a4, GPU FAH 11
WU details: 5767 (4, 206, 3735), 5770 (2, 158, 5195)

welcome to the F@H Forum Breach,
Depending on the WU assigned, it might take some time for the first percent to be completed so how long did you wait? On my GTX 260, most WUs take less than 1 minute to show the first percentage. Once the screensaver is exited, the screen might lag for a second or so than everything will work fine while the GPU Slot pauses. I didn't have to terminate F@H from Task Manager.
Can you please post your log, especially the initial section as it will contain information about your system and configuration of F@H. Do note that the Code Tag is available in the Full Editor.

Hi and welcome, GPU folding does not yet work on OSX or Linux, what operating system are you using?
Assume OSX on the mac.

OK, complete log here:

Basically when I exit the screensaver I'm looking at a blue (Windows 8) background for a few seconds and then my desktop is lagging for about 1 minute before it returns to normal, even though the GPU's are in 'stopped, waiting for idle' state. Is it normal to have to wait so much after the GPU job is stopped? Thanks!
Edit: And another example - left it on the screensaver a bit longer - that time it took even longer to get back to the desktop (still 0.00%...):

@kiore - sorry, the Mac is unrelated - this is about a problem I'm having on my PC.

IIRC, the 1 minute lag should happen only once with a fresh installation of V7. Does this happen every time or not?

Well, this is a fresh installation (I reinstalled Windows today too), but it happens every time... I can't seem to get GPU crunching to get going at all. Tried, rebooting, reinstalling the FAH client - nothing seems to help.

Okay, how about this:
Since you have a fresh installation of F@H, get
GPU-Z and start it.
Make the power level to Full
Does the GPU-Z show 90% to 100% on one or both of the GPUs?
You can filter the logs according to the Slots and you can post it here by using the Code Tags.

GPU-Z shows average GPU usage between 30-40% (!) on both GPUS. HOWEVER I did notice my VRAM utilisation sometimes being in excess of 800MB (GTX 295 has about 870MB). Coupled with the lag I suspect it might be thrashing to system memor which would explain the horrid responses... Is that a possibility? Thanks.
[Edit: At desktop my VRAM utilisation is about 360MB per GPU]

OK, so after spending 3 hours on this I deleted the two projects from the working directory and guess what? I'm back in business - close to 100% GPU usage (VRAM is about 840MB so I guess that wasn't it). Weird, weird, weird. Either there was something wrong with the projects or... I have no idea
I'm now working on project 5768 and 5769 and it's folding on Full with no UI lag whatsoever too.
If someone has any insights - I'd be delighted to be enlightened.

It could be that you got 2 bad WUs... highly unlikely but plausible. I checked the WU Database for records and nothing showed up so have marked it for a follow-up.
If your GPU was 30% to 40%, then it could be that the GPU was being "starved" by the CPU. The GPU needs a constant stream of data which is provided by the CPU. If the CPU is too slow or busy, it can result in the GPU being under-utilized. Are you running any GPU intensive application since 360 MB per GPU (720 MB in total VRAM) is a rather significant amount. For comparison, my desktop GTX 260 with 896 MB is using 499.19 MB with only FAHControl and HFM.NET running. The idle mode is around 100 MBs and under normal usage which includes folding, I get to about 750 MB of usage.
Nonetheless, am glad to you are folding now without any issues

Possible, though I don't think so... other GPU tasks start updating progress within 1 minute of download and this was was stuck forever at 0.00%... Also I don't have an other CPU intensive applications competing with FAH.

No nothing really - just Chrome. I did a test though - I rebooted - VRAM usage after reboot was about 110MB. When I start FAH it jumped to about 660. Then with Chrome and Firefox it'd go to about 330MB idle. + FAH that would become about 800MB
At the moment (things working properly) with Chrome and FAH it's running smooth while the VRAM usage is at 880MB. So although the VRAM utilisation is a bit unexpected I don't think it's the cause itself.
I think for some reason either the WUs or the core put the GPU in some sort of a deadlock situation which wouldn't clear itself. I have no evidence to prove it though - just the set of symptoms
I'll update if I hit it again with another WU. Cheers.

OK, my woes seem to continue. Now, I don't know whether it's related or not, but I seem to have the following issue:
Scenario:
1. FAH starts, I put it into Full - it fetches GPU WUs and starts folding - GPUs at 90% - no UI lag
2. I exit FAH, FAH control and reboot the computer
3. FAH automatically starts after reboot in Full mode
4. GPU folding continues, but:
- The UI is really choppy
- I have a HUGE number of increasing Virtual Memory page faults
- GPU utilisation is about 30-40%
- I give it some time to recover - it doesnt. I quit FAH - in about 2-3 minutes the core process quits and my UI is responsive again

Virtual memory screenshot when things the GPU is folding normally (before the reboot);
Virtual memory screenshot when things go to hell (after the reboot - note the delta!):
The page faults explains the choppy desktop experience but I have absolutely no clue why it happens. I'll now try to get a dump though for some reason Process Explorer always ends up with a 0KB file.
Am I cursed?

How much RAM does your machine have. What you are describing is a Windows feature where if it runs out of physical RAM is it page-swapping off the HD slowing everything down by a couple of orders of magnitude.
You are also noticing this behavior on reboot. Does it settle down after a few minutes? During a boot, Windows will be fetching lots of stuff till it gets everything important into RAM. This process will continue on for several minutes after the computer screen is up and taking instruction.
Neither of these issues are specifically folding related but I could see GPU folding lag being an amplifier of the bad user-experience while they go on.

Try setting the CPU slot to use 6 CPUs - go to Advanced Control -> Configure -> Slots -> cpu to do that. The two GPU feeders (FahCore_11.exe processes) need some CPU time as well, and in my experience they cause frequent HW interrupts, which may or may not explain the frequent page faults delta.
Unfortunately, choppy UI during GPU folding is more of a rule than an exception. GPUs don't have a priority system like the CPU/OS does. It's "first come, first served" only which tends to make the display unresponsive. You're better off pausing the GPU folding one way or the other when you're using your computer.
According to the log, the setup has plenty of free RAM, so swapping shouldn't be a problem. AFAIK, page fault doesn't necessarily mean swap file thrashing. AFAIK, it also happens when a (user) process needs to get outside of its process boundary limits to do something HW specific.
These parts of the log look weird though. Why isn't it showing an even 8GB for total memory? 64bit Win8 Pro shouldn't have any problems with 8GB (it can support up to 512GB). Some weird chipset limitation, perhaps?

Thanks guys.
@P5-133XL - I have 8GB of RAM and with FAH and all it never goes beyond 3/8 utilization - that's why I'm even more perplexed by that intense swapping. No, it doesn't settle. When I quit FAH after the initial boot (meaning waiting on all cores/processes to quit in task manager) and I start FAH again resuming the GPU units results in the absolutely same behavior.
@Napoleon - I stopped the CPU slot altogether - same story. I'm aware that GPUs can't prioritise, but when it's working normally (without the vm page faults) it works like a charm - barely any lag, when it's swapping... horrible. I'm OK with pausing GPU folding, but a) that behavior is not normal b) my gpus aren't fully utilized when running c) these writes will destroy my SSD where the swap file is
So the mystery remains - why isn't it swapping when it initially gets the WUs while after a reboot/resume it starts acting like that? Any ideas what next to try? Thanks.
