ok here is the deal.. my computer is
4 GB DDR2 800 mhz ram
and the new 295 gtx
previously i had a 8800 GTX card and every game i had ran very smooth.
then my 8800 gtx suddenly stopped working so i buyed a 295 gtx.. well my expectations where it should atleast we as fast if not faster than the 8800 gtx.
but that did not prove to be the case.. in company of heroes i have bad lag when much things going on, same with empire total war..
those games worked PERFECTLY with 8800 gtx
so i was wondering... my motherboard has pci-e x16 but not 2.0... what is 2.0? am i gimped if i dont have that? surely the card would still have the same bandwidth that 8800 gtx had so it still would not be going SLOWER?
an other thougth i have was what if the second gpu is not activated? my motherboard doesnt support sli, only crossfire.. does that mean 295 gtx will not work ? its an intel motherboard and intel only supports crossfire right?
it didnt say anywhere that 295 gtx requires NFORCE motherboard for sli
is there anyplace i can see if the second gpu is working? my computer DETECTS two gpu but who knows if the other is ACTUALLY WORKING? i tried nHancer but i get the same half green thing even if i active singel gpu mode.
i have tried drive cleaner and bios update.. no luck so far.
Hi ya. I can't answer all of your questions, but a few at least.
You don't need an Sli motherboard for the 295. Wether or not both GPUs are working you should definately be getting better performance than an 8800 - as more or less 1 gpu should perform like a gtx260. And an nforce motherboard is not required. The best way I've found to determine if both cores are working is to monitor the temps - hwmonitor is good for this, but there are plenty of others.
And yes, under load 42c is very low... in fact lower than mine is at idle, which peaks at 80c running a stress test (furMark).
It sounds to me like the card isn't working anyway near its potential - though I'll have to leave it to someone who knows more than me to tackle that one.
Just to check though, you are using the latest drivers?
Try installing the drivers again on top of the others, sometimes the GTX295 needs this in order to find the 2. GPU. I'v read about this problem on many gtx295 reviews. Personaly I did'nt have that problem.
i installed some older drivers and suddenly all monitor programs started getting readings from the second core too.. dont know if performance did improve but atleast it gets warm =) goes up to almost 80c
i scored 14000 in furmark 1024x768 MSA none.. is that good for 295 gtx ?
im only having 18a per 12v rail.. is that enough? i put three 12v cables and put two om em together to form one (with more amps im hoping) so that means 3x18a right? or doesnt it work that way?
I just had a similar problem with my EVGA 8800gt SC. The problem was I changed the power supply to an OCZ 4 rail at 18A per 12v rail. (thought I was upgrading) My card requires 26A on a 12v rail. I installed my old power supply that is an Ultra single rail 34A and all of my problems went away. I would check your video card box manual or even manufactures website to verify how many amps required to run your video card on a 12v rail. I hope this helps.
