Overclocking 7950

a66as · 27 Aug 2012 at 15:06

Hey guys, how would i go about overclocking a 7950? I have the msi twin frozr III. im using msi afterburner. Can i just turn everything to full whack and expect it to be stable if i leave the core voltage (Mv) where it is?

I tried to keep it at stock volts and put it on 1000/1575 but my pc bluescreened after a while

my stock volts are 1.031V as well

I tried again, 1.031V with a 1000mhz and 1575mhz memory clock, this time i moved the power limit (%) bar up to full whack (20%) and it seems to be stable so far. Ran 2x heaven benchmarks with every option on full whack and 1080p and got a score of 1103 and average fps 43.8.

Might try and take it up more

should i do 1100mhz first, or go straight to 1200mhz?

ill try 1100 and 1.175 next then

i use headphones mate so should be =)

it keeps putting my voltage down to 1.174 and it only goes up to 1100 on the core clock, im using msi afterburner as well

I tried it with the following settings

Core V = 1.181v
Core c = 1100mhz
mem c = 1575mhz

my temps rose to around 80-85 degrees and i only gained an fps increase of 3 (same settings everything maxed out)

a66as · 27 Aug 2012 at 23:59

Just ran it with those settings and core volt at 1.174

Temps were around 75-80 again

Fps was around 77

might be best if i keep it at stock volts with a 1000mhz core clock speed untill i get better cooling

Temps at stock volts is around 59-60 with a max of 61 at settings full whack, so it is probably my case cooling that needs improving

that fan was screaming at around 95% allready, i guess i could use different profiles for diff games?

OK try and run 1100 core at 1.165v then.

Check your maximum temperature when gaming and your maximum temps during benching heaven, and note your maximum fan speed. There are checkboxes in the afterburner monitoring section for all these.

What case do you have?

Your temps are a lot higher than mine, although I did reapply thermal paste on mine.

ill upload some pics of my rig later today

Tried bf3 today, the temps were fine they went to around 71 max, but what bothered me is i got some screen tearing on bright areas

a66as · 28 Aug 2012 at 18:28

nope, ill test it out on skyrim and some other games to see how it performs

a66as · 28 Aug 2012 at 18:40

Am using stock voltage with 1000 core clock and 1575 mem clock

This is what the card looks like in my rig, dusty i know

but my room is a dust magnet for some reason

a66as · 29 Aug 2012 at 02:10

1 intake at the front, 1 at the bottom, 1 exhaust at back and 1 at top. i could mount a fan at the side as well

My card just blue screened at stock volts with 1000 on core and 1575 on mem, it said a Driver is causing instability issues so maybe its the drivers not the card
