Well, i recently upgraded to a sapphire 5770 HD 1 gb card
Here are my system specs:
Athlon II x3 2.9 ghz ACCed to a (phenom II X4 b35 2.9 ghz)
4 gb ddr3 ram (1st 2 slots with ocz gold ddr3 1066 and third with 2 gb corsair 1333 mhz)
AsRock 785GMH/128M motherboard
Sappgire 5770 1 gb(juniper 40 nm)
OS: Vista ultimate 32 bit
PSU: a local stock 450 W (single 12v 14 A rail ><)
So it goes like this
I recently upgraded to the 5770 and tried our re5 fixed benchmark to test out he performance....I ran it at 1280 x 1024, 4x MSAA, All details high, and vertical sync off
the fixed benchmark gave VERY varied results, sometimes as low as 57 sometimes 66. So from what it seems like....i suspect it may be a botleneck somewhere, since i have seen weaker systems get higher fps with the card.
And yes the PSU is indeed a weird one....single 14A 12 V rail rail. it also did not have a 6 pin connector so had to use the 4 min molex to 6 pin provided with the card.
I have thought of changing the psu, but the decent ones are really expensive and i am kind of short on budget after buying the card for 210 USD.
Is it really possible for the entire system and that card to operate normally with just a single 12v 14 amp rail though( 12v running at 11.68V)? I havent had any crashes till now. Plus the gpu idles at around 41 and at load is around 63...so it isnt overheating because of lower power either, is it?
i checked AMD overdrive, and the card was using 1.15V when fully active and .95 when not....
Another factor could be the first 2 ram modules running in dual and third in single.......two of them are definitely running in dual as the bios and cpuz show it. Some guides even suggest all 3 may be running in dual.
The I can only only think of these two as the limiting factors....
Please help!
