Is it still 1 core per GPU for folding, or should I dedicate 2 per GPU?

As far as I know, it's "as needed" Faster GPU's on slower CPU's require more threads. You'll just have to experiment.

The happy days of GPU crunching ended some time ago. Now its plain CPU. Btw nice job you are doing in the folding section. Your CPUs are most welcome here.

I'm moving the CPU cores to crunching and the GPUs will be folding so I was asking how many CPU cores I need to dedicate to each GPU for folding so I can allocate the rest to crunching.

Alright I'll play with it. I have fast GPUs crunching but the machines running GPUs for folding are Haswell-E.

Right, I misunderstood you. Core21 units uses less than one core. Core18 uses one. If you use the rig when its folding leave a core for that as well.

Alright thanks. These are dedicated machines for the most part.

Okay, so, thanks to the awesome donation from @Random Murderer , the amazing continued support for ole uncle @Kreij and the amazing work that our WCG captian @Norton does, I won a pair of frigging awesome HD6950's modded to 6970's!!!!!!!

Now then, I have an Asus P5Q-E board that I got some time ago from the awesome @theonedub , an ole Q6600 SLACR chip, 4 gigs of DDR2 and these sweet pair of HD6950(70)'s.

Now, what does everyone figure these cards will produce in daily PPD?

I am planning on putting these puppies to work for the Folding team and just wondering what I could expect in PPD.

Thanks a ton in advance.

They will keep the room warm but pre-GCN/anything older than a Radeon 7750 don't really output too much in ppd....

Well dang, that kind of sucks.

riser cables / GPU rack questions

Looking for recommended PCI-E riser cables in order to run 4x air cooled 3 slot cards on a RVE board and I figured you gents would know what to use and what not to use.



Thank you for your time.


Also if there are any pre-made racks/stands for such a rig available let me know.

I have never used them but I think @BUCK NASTY did. I also know of a folder on OCN that used them.

Spotswood makes racks.

Riser cables are pretty basic. Just make sure to get one with a molex power adapter included for added peace of mind and stability.

Not sure what "case" @BUCK NASTY used, but here's a picture:

That is the guy. He was moving back to the US after his deployment and I have not heard from him.

Thanks, I think I'll be able to whip something up from Lowe's/Home Depot for a rack.

Grabbed 4x PCI-E extenders off of Amazon, ready for some Futuremark now.

The hard part will be getting the SLI bridges correct

Shouldn't need SLi bridges if your planning on folding. Unless your just shooting for HUGE numbers on Futuremark.

Which MB are you using?

Never mind...

Futuremark it is for me.

In folding you just disable the sli/xfire feature in nvidia/amd client

Actually you don't need to disable XFire when folding as F@H doesn't support XFire for folding but it will still use both cards as normal even with it enabled as that's how I had it running with 2 HD7850's F@H found both cards and set them up correctly as GPU Slot 0 and 1

 

[DarthBaggins]

In my experience they run better with it disabled but that's just me I guess also if your running them in Linux definitely disable

Anybody have any experience with Windows 10 and voltage control on GPUs?

As far as I've seen you shouldn't have a problem in 10 if your card supports it then it'll work just use Trixx or whatever other 3rd party Overclocking program you have as your choice

 

[agent00skid]

Asus GPUTweak 2 goes to shit, Trixx can't control voltage and Afterburner can't control anything.

I think that you have to live with the default voltage on your new Asus 280X. It was good enough for some OC if you remember to lower the RAM speed to 1500 MHz.
