2 8800GTS 640mb on CrossFire mobo (Asus P5K Premium)

[SKORPI0]

Got a B-stock 8800GTS 640 Rev2 from eVGA. Currently using a Rev3 on my system.

Asus P5K Premium, Q6600 G0 @ 3.2 GHz. 2nd PCI-Express x16 slot operates at x4.

Rev2 Oc'd at 621/1458/1944 (12184 - 3DMark 2006)
Rev3 Oc'd at 675/1560/2100 (12541 - 3DMark 2006)

Will I get any performance improvement (if any) or will getting a 680i/780i mobo be much better. System is about 6 months old, so $$ is in consideration. Not a big gamer at all but would like to have it capable of doing so, just in case.

i hope you're not serious. SLi is fundamentally impossible without an nVidia chipset. you need 680i/780i for it to work.

Sell the P5K and get a P6N diamond if you've got both cards.

You'll break even and have a system that you can actually use. If you're worried about being able to overclock on a 680i..I've heard of 6600's that run ~3.5GHz without a ton of voltage on nvidia chipsets.

I know, no intention of using it in SLI mode since I'm aware it is a CrossFire mobo. Trying to save $$ at the moment.

Just bought it cheap @ $199 vs. $350 for rev.A3 last Sept. My eye is on a 780i mobo in a few months and keeping the 2 cards till I do the upgrade to maybe a 8800GT/9800GTX.

Looks like i'll have to hook them up and find out.

Last time i checked, the only thing stopping SLI from working on Intel chipsets was nVidia's own drivers.

But does the actual reason matter? It doesn't work. PERIOD.

.

What do you hope to accomplish? All you are going to do is burn more electricity.

There is a modded version of drivers that will work. Its a forceware version 88 something. Just google it, its there. I dont know if they will work with an 8800 series card. They did pretty good with an older card. I have looking for someone to mod a recent set of drivers, bug I guess noone knows how too now.

Well, that's just it.

That's not really true.

If the guy who used to make hacked drivers still was making them, we'd be running SLI wherever we desired.

If it's merely a driver issue, how can the 9800 GX2 operate in SLI mode on a P35/x38? That little chip on the primary GX2 card allows it, somehow... but how?

The point IS, that guy doesn't exist so we CAN'T run SLI on Intel chipsets, I don't know what you are trying to argue about and I don't see what relevancy it has to the topic at hand.

Sorry if I sound rude but it's 4AM over here.
