GTX560ti Problem

[Liam123]

Just replaced my old GAINWARD GTS250 with a GIGABYTE OC GTX560ti and the fitting went well, my pc boots and all the drivers installed fine. Its just i think i may have a power problem as the default memory clock for this card is 2048 but GPU-Z says im only getting 1002 also when i tried to game on DIRT 3 its just a green screen.

SYSTEM:
AMD X6 1090T @ 3.2GHZ
ASUS M4A78LT-M MOBO
GTX560ti
OCZ PSU 500W


GUYS IS THERE A PROBLEM WITH THIS CARD THERE IS LOADS OF THREADS SAYING THAT THIS CARD IS UNSTABLE LIKE MINE I MAY RETURN IT, MY OLD GTS250 IS BETTER

I also had some problems as the system powers down sometimes

Do you mean memory clock or size

Memory clock is 1000MHz x 4 for DDR5 which gives 4000Mhz bandwidth. Memory size is possibly 2048Mb? or 2Gb? Usually 1Gb

OCZ is not renowned for power supplies, can you try another?

i dont know not too good with all this stuff its just something seems wrong i cant even get on DIRT 3 my old GTS 250 could and play it stable, windows also asked me to change to a basic theme as my performace was low

 

[Liam123]

got this not sure what it all means is anything wrong with my system?

Don't forget at idle (in windows) cards reduce clock speed to save power.

Download and install MSI afterburner. Play a game for a while. Pop back into windows, open up afterburner and check what the GPU and memory clocks went up to (check the graphs). Check against the specs for your card.

What drivers have you got installed?

As above, install MSI afterburner and run furmark/MSI klombuster for 10 minutes and monitor temperaters. Also try a couple of benchmarks and compare to others who have a GTX 560.

Do you have a link to your exact card?

Both pci-e power connectors securely attached to card and/or psu?

temp is fine, have you got any other games installed to try?

 

[Liam123]

I dont know whats the going on the card is just been strange sometimes its very quiet sometimes its loud and my PC just randomly turned off while playing a simple game

maybe the voltage is too low for the OC
