You might want to try EVGA precision. It normally comes with an EVGA gfx card, but you can get it from here. Riva Tuner is also available here, at same url.

I didn't bother myself, because every time I've tried to overclock a gfx card, it seems to make the system less responsive when I want to do something on the computer. Even if I got it seemingly completely stable. In the end, I just figured it wasn't worth it. YMMV.

regards, Gizbar.

Yeah I agree, Overclock Yer cpu if You can, But the gpu? Forget It, The results just don't seem to be worth It.

Yea I downloaded the Riva you said but I didn't know what to do so I left it alone and went for the CPU instead and am very happy I could get it this far. At 3.8 since last night with seti running I am at CPU 52C really like this little H50 sure suprised me how well it works.

And no good credit hound!

Maybe jumped in little late, but hope not too late..

Sure you can OC your GPUs.
This will speed up the calculation time.
Don't know how, so I bought 5x manufacturer OCed GTX260-216.

Because of 2 or 3 GPUs.
You must look how the PCIe slots are connected.
Sometimes if you insert a 2nd, the speed go down.
On your mobo now it stay at PCIe 2.0 x16 ?
Or at PCIe 1.0 x16 ?

You looked with GPU-Z how the speed is @ all connected GPUs?

Every GPU should use PCIe 1.0 x16 or PCIe 2.0 x8 slot for max. GPU performance.

Maybe your 3rd PCIe slot is 2.0 x4 ?
Then you would see some performance loss.
Don't ask me how much. Someone made a test here.. don't know where the thread is.
IIRC, maybe ~ 2 or 5 %. [EDIT: IIRC it was one of the 7/8/9xxx GPU series]

Both my slots are 2.0 x 16, so I should be fine. I used to overclock my ATI card but the program would auto overclock and that was what I used.

What Sutaru was talking about is on Page 2-20 of your P6T SE motherboard manual & all of your two main x16 slots run at x16 even if you place cards in all 3 slots.

Some motherboards lower the speed of all PCIe slots when you insert cards into them. An asus board I had would drop all the PCIe x16 slots down to x1 if you inserted a x1 card into any of the slots, even the x1 slot. *smacks asus upside the head*
Luckily a lot of the newer boards don't have this problem.

Was on a budget and bought the open box, no cables or manual...How was I to know the i7 is a totally different beast. I have the manual downloaded but never printed it. Like most things I usually chuck the instructions anyways...LOL

I meant it in an other way..
You could be also correct.. I didn't had your experiences.

For example I have the - now very old - Intel D975XBX2 mobo with QX6700.
It have 3x PCIe 1.0 x16 slots.
1st PCIe x16
2nd PCIe x8
3rd PCIe x4
[electric]

If I have a GPU in PCIe 1, the speed is @ x16.
If I insert a GPU also in PCIe 2, the speed of both GPUs are @ x8.
The 3rd PCIe slot is always @ x4.

AFAIK, the first both go through the northbridge.
The 3rd through the southbridge.

My system now:
1st PCIe slot with OCed GTX260-216
3rd PCIe slot with 6200 LE, only here display connected.

I actually download and read the book for a motherboard before I buy it, but I'm just nerdy like that. Recently I've been looking at 1156 boards so I can rotate one of my two main machines into the living room to replace my old P4. As it really just can't do all of the media things I demand of it.

I knew it was an Asus thats why I bought it open box and saved a bunch. Asus customer service has always been awesome to me. If you look at the beginning of this thread that is what I started on bit was coaxed onto the 1366...LOL
Newegg has some good deals on open box Asus boards if you have 5000 cables and extras like I do. Other than connections the manual would do me no good as all the setting are so different from the 775 I am used to that they may as well be Greek. I got my overclock by copying a nice guy that put all his bios settings pictures on an overclock message board. I can do anything as long as I have Pictures....ROFL!

Sounds like your board is very much like mine. My manual includes a block diagram of how everything is wired which is nice to have. A few pages later my manual says PCIEX16_1 runs at x8 mode when 2 graphics cards are installed. So I get 1 - x16 slot or 2 - x8 slots. I wonder if this also happens if I put x8 raid card in slot...

A x58 motherboard I was looking at was designed to run 4 slots @ PCIe x8 or 2 slots @ PCIe x8 mode. Motherboards like P6T6 WS Revolution let you run 3 slots @ PCIe x16 mode.

I use to think "hey it's an asus board it can't be bad". Then I bought an Asus Striker II NSE board a few years ago. After having the vendor exchange it 3 times & then getting two directly from Asus I gave up and took out my frustrations on it with a hammer.

Ohh.. this are Intel mobos, right?

Then I must make advertisement for AMD..

In the time (for around one year) I was looking for a mobo which have 4x PCIe x16 slots, I found only one mobo.. MSI K9A2 Platinum.
If two GPUs.. you have 2x PCIe 2.0 x16 (electric). If four GPUs (like I have) you have 4x PCIe 2.0 x8 (electric).
So very well for CUDA crunching.

Glad I didn't get a Striker....LOL What can I say since my first 486 never had a bad deal. Poor computer you showed no mercy.

Well.... it had it coming... lol

Asus boards have served me well for years. Everyone one them that I still have works fine. I have sold a few. Most of the ones I've gotten rid of just went into the recycling bin as no one had a use for them. I might put a few others there soon. Like my Asus P4T with it's 1.4GHz S423 P4 & 256mb of rambus.

Asrock X58 Supercomputer motherboard has 4 pci-e slots, But when all 4 are populated they all run at 8x, The driver is the limiting factor though as Nvidia didn't think people could and/or would want to run 4 GTX 295 cards on a motherboard. :(

It's actually a 775 C2D board Gigabyte GA-EP45T-ED3P. I expect the video card would drop to x8 mode if anything is placed in the other slot. not that I have any other PCIe card around to try.

Oh, Well that's different, Me I have a pair of P35 Asus P5K Deluxes, Both have a 16x and a 4x pci-e slot, Right now 1156 is just not doable for Me, I'll be lucky to upgrade a case, get a new case, get filters for all 3 cases, get a 950w psu and maybe add a video card later, But not in that order of course.

How about this one, Asus P6T7 WS Supercomputer
7 PCI-E Gen2 x16
No matter what your preference is, seven PCI-E Gen2 x16 Slots gives you the sufficient I/O interfaces to fulfill your demand for graphic or computing solution. You’ll be able to run both multi-GPU setups. The board features SLI on demand technology, not only supporting up to three graphics cards in a 3 way SLI but also supporting up to four double-deck GPU Graphics cards. Whichever path you take, you can be assured of jaw-dropping graphics at a level previously unseen.

P6T7
Sure wish someone would buy this for me...

There's also the EVGA 3 way SLI offering. 3 x16 + 1 x8 PCIe slots. Of course you need an Extended ATX case ...
