Guys, i just got myself an Gainward 4850GS from a forumer here..
It's 2nd hand but still quite brand new coz it was purchase like last month or last 2 months ago i think..
Anyway after receiving it i had a few probs with it, when installing it was no prob but everytime i tried to test its stability using 3dmark vantage it would load the jane marsh bench halfway thru then the computer would restart..
I tried a few times already... I install n uninstall drivers like a few times already..
I always notice that about haf way thru load there would be some artifacts appearing before my pc restart..
Sometimes after the restart at the desktop would appear some artifacts which would go away if i open up a window or something..
I tried downclocking the gpu n it's still the same but when i downclock the mem to 1ghz only then it would run the test stabily..
Is this normal for a GS?? For your info the GPU heatpipe is copper..
Please guys need help here..
Thanx for ur help n time..

It couldn't be the psu prob coz i can use my 4870 no prob..
I run tons of test and played games with my 4870 and never once did it restart or anything..
Don't tell me 4850GS suck more juice than a 4870...

Still can eh? Hmmm i gonna try pm netraid ah see how..
I'm really pening thinkin bout it, i even tried using different pcie connector still cannot..
Haihhhhhh...
Usually how long can i get back the RMA??

Added on October 31, 2008, 12:23 pmThat's why i been pm'ng u.. I myself is kinda confused already.. U said u could play no prob but i can't even pass the benchmark test..
I had tried test games benchmark eg DMC4 & WIC but not with the mem set at its stock 1100mhz but at 1000mhz..
It ran ok but i had to lose out the extra mem bandwidth ah.. Don't want ler to use a cripple card meh..

The temp at idle is kinda like the temps i get when i was using the reference 4850..
If i'm not mistaken around 6x idle and at full load i'm not sure could be 7x~80c i think.. Fan speed at 40%..
I've already taken it out and using my 4870, hmmm i'll try again later ah when i'm back from work..

Haihhhh.. Maybe it's just my damn luck ah..

I'm using Silverstone ST56F 560watt.. Running a 4870 just fine..
U need at least 500w and above kot to run it..
But if u got a true, true power psu like my friend enermax liberty 400w i think u should be able to run it on a 450w PSU..
My friend can oc his C2D up to 4.0ghz plus use a oc'ed Gainward 4850GS just fine on his enermax liberty 400w..

Aiyoooo, like this eh? Just when i want to send u my GS for RMA..
Soooo netraid regarding me wanting to RMA my GPU how??
Still send to u or whut?
Is scanart going to accept warranty for Gainward distributed under u?
