MSI 7870 HAWK not overclocking

[dmonroe89]

So just built a system a couple weeks ago using:

FX-6300

Asus 990x evo mobo

corsair h100i

Msi 7807 hawk

600watt thermaltake psu

2 X 7200rpm HDD

128gb vertex 4 ssd

6 120mm fans .

so the problem is using msi afterburner at well known and frequently used settings nothing crazy i can use kombuster and will seem fine no problems (usually runs for about an hour) . but if i play a game such as tomb raider in blue screens. everything run perfect on stock settings. could this be my psu ive used wattage calculators and they said i still should be 150watts in the clear. kinda got me stumped .

Overclocking is not guaranteed. 600w PSU is also plenty.

Silicon lottery, not every chip is going to overclock well or maybe you're just pushing it too far. Kombustor and a game load the GPU differently as well. When I was OCing my GPU I'd find I could run Furmark for quite a while but within 30 secs on running a Crysis benchmark there'd be artifacts everywhere.

did you overclock the memory too?

sorry life happened haven't been on :P , i have tried many different overclocks. i have used the same ones slick uses in his test and for me will play a game I.E. tomb raider

for about 30 sec and will just blue screen or the driver will fail. my normal operating temps are idle 33 deg C and and 78 deg C on normal gaming loads at stock settings . my case is extremely well ventilated with alot of air flow.

What does your blue screen message say?
