SLI'd 8800GTX = Huge Headaches

post #1 of 32
Thread Starter 
So last week, I added a second 8800GTX. My power supply is Nvidia certified for dual 8800gtx and everything else was ready as well. Installed it and ran futuremark benches. Everything ran without a hitch. then I tried to install the games I run. Call of Duty 2, Battlefield 2, Ghost Recon Advanced Warfighter, and FEAR.

COD2 would run but crashed periodically. If I disabled SLI, it ran fine.

FEAR BSOD'ed after installation. I was able to get it to run after updating the patches but it also crashed periodically. No SLI, runs fine.

Ghost Recon never ran once (ironic as its included with both of the Asus 8800GTX). Again, turn off SLI works fine.

Battlefield 2, runs but with numerous crashes (once the computer rebooted). Again turn off SLI, and it worked.

I reloaded my system from scratch with all the latest drivers and even tried swapping out for a different 8800gtx with both cards rotated. No difference. Checked with nividia and Asus (and BFG, the other card I had). No helpful advice. Downclocked my overclock on my cpu to stock, unplugged all my fans (to take some of the load off the power supply) still no luck.

What I find most interesting is that throughout this entire process, the Futuremark demos have run without a hitch. Also I could run multiple instances of rthibl and really push the cards in terms of temperatures and performance without a single crash.

My final thoughts, in conjunction with what I have researched off various forums is that the drivers are not mature and that there are potential issues with various games. The futuremark demos and rthibl running (two instances simultaneous) demonstrates that there is no actual hardware issue, or deficiency in the power supply, but rather that it is software related.

One card runs fantastic.

To that end, I returned one of the cards yesterday and bought:

Viewsonic VX 922 19" LCD (my CRT is about done)
Western Digital Raptor X (my 74 gb raptor is getting a bit crowded and the new X series have 16 MB cache)
Antec 900 (Time for a change as I've had my armor for over a year and a half. time for something new).
Zalman VF-700 CU (for the passively cooled 7600GS in my daughters' computer).

The final tally is that i still have $12 in my pocket after the exchange

With regards to the Antec 900, I'm going to begin modding it today.

First, I'm removing the large rotating feet from my old armor case and mounting them on the 900. The 900 has low profile feet and as my case sits on carpet,I want it elevated. All I will need to do is drill 8 holes in the base and screw the feet in.

Second: Paint. After the success of painting my armor, I am going to paint the interior of the 900 flat black.

Third: Add a 120mm Thermaltake Thunderblade to the door mount of the case.

Fourth: Wire-gami. I'm pretty good at wiring cases and just picked up a fresh supply of black zip ties. Because of the orientation of the fan on the Silverstone Zeus, I'll be able to mount it right side up (Rather than upside down like the OCZ for example, as its 120mm fan is on its bottom). This will put the wire bundle flush against the back of the case. As I intend to re-arrange the drive bays, the bottom bay will be left empty for me to feed all the extra wires into. My only concern is feeding the 8 pin power connector to the top left of the motherboard, but I'm certain I'll come up with something creative.


Pictures soon to follow


In summary, although it was nice to have two 8800GTX, really the only benefit I could see is in benchmarks and bragging rights. I assume at some point, I will buy a second card (once the drivers are matured) but thats definitely down the road. As I run games at 1280x1024 and can do so at max settings with a single 8800gtx, unless I go to a true huge monitor, there isn't much point. I'm glad I returned it and exchanged for a bunch of new goodies.

Well, it would seem that SLI is not needed yet for the G80s. Most games are not made for that kind of power. My system doesn't lag anywhere...ever. I only have ONE 8800GTX.

Its amazing what you can buy instead of ONE 8800 GTX. Hope you like it!

I returned my other 8800GTX as well, as I had driver issues and felt I didn't really need it at the time.

Your daughter could be bragging that she has passive cooling on her 7600GS at recess . And for show and tell she could bring screenshots of your games, hahaha..

Anyways that was a pretty nice return you made!

dude I would of splashed out and gotten a bigger screen than that 19". Something like a 24" would be more suited to one of those 8800GTX which can handle the higher resolutions.

Quick send it back and get a 24", 2ms, 100,000/1 screen that will make your eyes bleed

Edit: BTW, the main benefit of the X series raptors is not the 16MB of cache, which is pretty much redundant unless its used in a server with excellent NCQ support. The main benefit of it is the native SATA support (no more of that rubbish SATA to PATA bridging) which pwns, meaning you can get true 1.5Gb/s burst rates, compared to the limited 1.33Gb/s of the old raptors.

The funny thing is, my mobo has no SLI and I spent like $100 or more less than some of you guys. My Graphics are the same, but I used the money I saved on my mobo to buy some $100 Ram (Corsair XMS2 x2 512Mb DDR2 675) for my second rig. Which, if you want to know, can do the same thing in most games as my main rig.

Lol. Take into consideration that I'm 40. If I didn't have that kind of disposal income by this point in my life, it's likely I never would.
