Hey guys, I just recently put another 8800GTS ( 340 MB ) The difference is one is a XFX card, clocked just a bit higher. Now, since i put them in SLi, ( i re-installed my video drivers after doing so ) my computer has been crashing, and freezing a lot. Now it even BSoD's whilst play css.....

My PC

AMD 64 4800+
2 8800 GTS's 340 mb
2 gigs of Ram

If you need to know more, just ask.
 
What PSU do you have? How many amps on the 12V rails, and the combined watts?
 
If you cant fined any issue with your OS, it mite be a hardware issue.
read the manual see if that card requires a higher watts than your power supply is now.
Not having enought amps will make to system unstable.Thus crashing.
 
Please also provide the STOP Error on BSOD. It's hard to troubleshoot an error if you dont give us the error.
 
^^ turn off your case Move those hardrives and LOOK its not that hard if you need help ill bring cam to show the good people if so call me lol 1-250-***-**** lol

How do you think I came to that conclusion ? I took out my HDD's, and looked... If i didn't, all it'd say about my SPU is " iunno. "

you're no help :'(
 
If you can't provide the BSOD error, how about the Event Viewer? It should (read: might) record something before Windows crashes. Be sure to check both the system and application logs for anything useful.

As Hardhat and Dweeb pointed out, it'd be useful to know what the current and voltages are for your system. If it's unstable - normally, but not always - it'll just reboot. Here's an application to look at your hardware levels:

Well if that is your PSU you probably don't have enough power for 2 8800 GTS's its only 400 watts.

Minimum System Requirements

* 1GB of system memory
* CD-ROM drive
* 50MB of available hard disk drive space for basic driver installation
* Microsoft Windows XP operating system
* PCI Express-compliant motherboard with one vacant PCI Express x16 slot
* Minimum of a 400 Watt power supply.
(Minimum recommended power supply with +12 Volt current rating of 22 Amp Amps.)
* Minimum 450 Watt for SLI mode system.
(Minimum recommended power supply with +12 Volt current rating of 24 Amp Amps.)
* An available 6 pin PCI-E power connector (hard drive power dongle to PCI-E 6 pin adapter included with card)
 
1. My cards don't light up.. at all
2. It MIGHT be my weak PSU, I'd have to talk to my dad bout it.. i have another one kicking around.. but playen today. It's been running smoothly.. no crashes or BSoD's... but we'll see
 
Your Thermaltake PSU isnt SLI certified, now even if you dont believe in those stickers, at least it tells you that its capable of handling two graphics card sucking juice from the 12V rails.

If you do want to run the 8800GTS 320s in SLI, try searching on newegg or wherever you buy pc parts from for the: Corsair HX520.

You might get away with playing chicken running one card on an average PSU, but when you're running two cards, never go down the cheap route and look for bargain PSUs. Better of coughing up an extra 50 bucks than 500 when the PSU blows and takes every component with it.
 
There's a 600W PSU that's SLI certfied with ~28 amps IIRC. That's nowhere near what SLI needs in a modern setup.

You've got 30 amps on that PSU (unless I missed something). You're going to have a bunch of crashes. I'd recommend you upgrade it before it takes your whole system with the next crash.

~Gooda~
 
Well, you could run two 7600GT or 8600GT with that 600w power supply. :p But yeah, the SLI stickers aren't a proper indicator.
 
hmm, well thanks for letting me know about that guys, Actually... I think my dad was having issues withe SLi on this machine. I have another PSU sitting around, which is 550 watt, and claims to be SLi ready. Would that be any better ?
 
There is another option you have missed: The automatic reboot on failure is defined in the BIOS. Go in to bios and turn it off. Then repeat the problem. The error will start as 0x - Gather this code. Post it here please. Then we can correctly identify the problem instead of guessing what it could be.
 
Nah, you guys were right. Lacking power. I grabbed a 250Watt Thermaltake Video card PSU, since i put that in. Ain't had an issue. thanks for the suggestions !
