I want to make sure I am getting the most PPD out of my cards I can. Current cards are FTW 1080TI and Founders 1080TI, CPU 7900X. I looked at GPU's and I am at 85% load. Is that normal do I need to overclock my CPU higher to keep the cards feed. Currently running 3.99GHz on CPU.
When getting these stupid small work units I am getting around 890K PPD per card. On big point work units I am getting 1.2M PPD per card. But it seems 99% of the work coming out is the small work loads.

yea, 85% gpu load is normal. these work units are not designed to run on the latest hardware so can not take full advantage of latest features. most are designed for fermi and CUDA, which is nearly 8 years old now...

If you wanna get the most PPD out of your cards, make sure you're running Linux. At least a 15-20% PPD boost. In windows you need at least 1 core per card, not the case in Linux. Windows blows for folding.

i have yet to hear of such a claim and/or numbers behind such a claim before for linux. can you enlighten me on this? if not no biggy, just one more thing to test on my next test build, dual core celeron with hyperthreading running 8 1080ti's?!?! yes plz!

What kind of board supports 8 1080 Ti's? My GTX 1080s utilize 52% of their 8 PCIe lanes, so 4 lanes would barely bottleneck them, but you would still need a board that could bifurcate the PCIe lanes into 8 4-lane slots.

oh, well my plan originally was a hyperthreaded quad core with risers, see if the performance drop is within reason to justify the lower cost per GPU for the system. if i see good performance on risers with linux, like some claim, i will have data to support/debuff these claims that i'll share will the folding community. and with this latest statement it seems i should also try throwing in a MUCH cheaper CPU dropping the cost of the system per GPU by an additional ~$35 to a low ~$140 per GPU. currently my cheapest dual GPU rig sits at ~$200 per GPU so this will be a very fun test, when i can get the funds to build it... (hopefully mid/late january)

Well I would say the fact that I have a 1080Ti currently running in a system with an AMD A6-5200 and the CPU utilization is always at 1% and the card is constantly folding at full speed, should tell you something (in windows it always pegged one core of my Xeon). The same system in windows when it had a 1080 in it wouldn't even score 400k! When it had a 1080 in Linux it was scoring well over a million ppd. With the 1080Ti it averages 1.2 million on those nasty 94xx WU that make the 1080Ti only score 980k in windows.

Again that's a problem with Windows. From reading the folding forums, Linux will let you get by with a minimum of 4x, with no hit on the score. 1x will sadly hit you for about 10-15%. Windows is very inefficient for folding. You can thank all the gaming that takes priority haha. My 1080Ti in Linux uses maybe 5% of the pcie bus.

These numbers seem about right to me in my experience. None of my rigs have more than 2 cards though. If you want more ppd look at Linux. Yes it's a little harder to set up but if and old man with no computer skills can do it anyone can.

Chris21010 made a very easy to follow, step by step walk through for doing a linux setup. Now if only there was a way to have a linux guest in a windows host other than server 2016. ARG. I hate the fact I am stuck in windows and I am losing 20% to bad drivers. Windows Server 2016 Hyper-V allows full hardware passthrough of the GPU to the VM's where as ESXI, VMware etc only support it on GRID cards.

Have you tried virtualbox? You probably can't gain too much if you're in a Windows environment anyway. I'd follow the guide and get Linux as a boot option beside Windows. You can always virtualised Windows from linux.

Looks like they all run that low.
why is one of your core clocks under 1500 MHz? was this just one of those random power drops F@H shows every now and again while working?

Yes that is all it was, mostly see that on P94xx WUs.

I have and the guest addons do not give you full access to the card. If I was running linux as a host, there is no problem giving windows full access, but sadly, there is no real way to do this from windon'ts. I've tried everything. I'm at the point where I'm just going to build another system and put my card in it and run my main box with a 210 or something :/. And then eventually sort out all my video files to a file server.
