I vaguely remember seeing someone ask this sort of question elsewhere, but can't remember the answer.

I have a P35 775 mb, with an open pci-e slot. Now I know this board won't run SLI, but would it be possible to put another nVidia card in the 2nd slot to fold? And yes, I know it's only 4x 1st gen

yes it is

I'm currently running 4 Nvidia cards on a 790FX-GD70. All cards run 100% fine with no issue, so your setup will work as well. You'd likely be able to get SLI running on that if you could find some of the hacked drivers that people have been talking about recently.

I'm running 2 Nvidia cards on my 790GX and its working fine(after i "tricked" the board) so i think it will work. Also the hacked drivers don't work in every case (aren't working for me or velvet)

It'll work, I ran 2 Nvidia GPUs (9600GSOs) in the P35 Asus P5K-E folding for a while. Needless to say, SLI wasn't supported, but the second card folded fine, even with only x4 bandwidth (PPD was identical to first card)

 

[King Wookie]

thx for the feedback.
Not too worried about SLI, as a 260 at 1680 res is more than ample.

Anything else I would need to know about setting it up?

Not really.

If you have 2 monitors/dummy plugs, download the 2-GPU option from http://www.overclock.net/overclock-net-folding-home-team/458455-guide-multi-gpu2-folding-guide.html, but remember to change the name to your name and the team number to 50711, we can't have Overclock.net stealing our PPD

Unable to fold on 3 cards simultaneously!!

Guys,

I have this mobo on my second setup

ASUS P6T6 WS Revolution with NF200 3xPCIe true x16 LGA 1366 Intel X58 ATX

CPU: i7 920 OCed to 3.8GHZ
RAM: 4 GB Kingston HyperX
PSU: ZM460B-APS w two 6pin PCIe connectors

I installed the foll video cards on the foll slots

9600 GSO: Blue Slot 1
9800 GT : Blue Slot 2
9800 GTX: Blue Slot 3

Just got the 9800 GT today. Before that, the setup with two cards was folding good. When I add the third card, though all the cards fold individually well, the system hangs when I try to go for multiple clients. Just to remind tht the XFX 9600GSO card requires a 6 pin PCie connector. Since the two from PSU is already used up by 9800GTX, I used the 2 molex to 6-Pin PCIe Y adapter.

Is this because the setup is not getting enough power??

Appreciate your help guys!!

 

[mstenholm]

As far as I have read then the HX comes with 6 times 6+2 +12 V from the same single 12 V rail. You have enogh ampere but do you have all the cables? Power is not your problem.

 

[dustyshiv]

msten,

The rig in my specs folds on three cards no problem with the HX.

The rig that has the problem is my second one and it has the foll spex as mentioned

That is probably a power issue. You are running a 460w PSU on a heavily OC'd i7 and 3 video cards. The general rule of thumb I think is that a PSU can run as many cards as it has enough PCIe connectors for, e.g. your board and a 2 PCIe connector card would be "safe", plus maybe a connectorless PCIe card e.g. 9600GT, 9800 GT Eco. I would definitely upgrade that PSU, I bet it runs really hot.

 

[dustyshiv]

Jstn,

Yup...The PSU runs hot....a bit too hot...Used u my funds to get this 9800GT....The PSU will have to wait. I wanted to make sure tht its the PSU..

 

[DanishDevil]

Dusty, I've still got my Enermax 625W for sale if you're interested. I ran a heavily OC'ed i7 system and a GTX 260 on it without a hiccup.

Maybe you can remove your 9600GSO and swap it for the 9800 GT while you are waiting on a new PSU, unless your GSO is really overclocked and gets higher PPD than the 9800 GT.

Done tht bro!! The GSO is the one left out now!!

Dusty, Overclocking an i7 uses a ton of watts. According to the eXtreme Power Supply calculator, the CPU alone is using 289 watts when you overclock it to 3.8 GHz. I'm amazed you can get it to boot!

Those calculators over estimate by quite a bit. That said, I wouldn't want to run an OC'd i7 and a single gfx card on his psu. I prefer a bit more headroom. Helps the psu run cooler and last longer.

Agreed. Still from everything I've read, overclocking an i7 is a wattage eating monster. I wouldn't even consider running that board and proc at anything less than 750 watts. Maybe a Corsair 650.

I too like around a 200 watt headroom. Like you said, the PSU runs cooler.

 

[dustyshiv]

Ok Guys!!

Seems tht the PSU was the issue. My friend had this Corsair TX750w powering his phenom 9950 at stock and no VGA card. Just borrowed this PSU from him and lent him my Zalman 460w for the time being. Hooked up all the cables and video cards. Now...all the cards are folding happily!! Think they were starving for power initially.

One more question guys....

Have anybody folded on more than three cards on a mobo??

Thanks again for the suggestions and support!!

Hey we dont call ourselves folding/crunching family for nothing!!

 

[theonedub]

Dusty,

BuckNasty runs at least 1 if not 2 or more Folding rigs with quad GPUs.

I have 5 rigs with 4 GPU's per board. All Mobo are MSI K9A2 Platinums. With Nvidia, CPU usage is not an issue. I could (and have) feed all 4 GPU's on one core of the CPU. It's best to match the shader count between the cards to avoid conflicts.

XP?

WOW!

I'm just sitting here lusting after being able to acquire a second card for 750i.

 

[BUCK NASTY]

XP?

All the way baby! I just re-installed XP on my 780i rig as well.

WOW!

What card are you running already? I may be moving some inventory very soon.

 

[DanishDevil]

Hey guys, just checking. Should my GPU's activity be spiking minimally like this while folding? This is during a 1888 point WU on my better GTX 285.

 

[thebluebumblebee]

yep, that's the way the 1888's run. Notice how cool your gpu is.
