Finally got to OC my V1 5770

post #1 of 8
Thread Starter 
so when i first got this card i had a cheap PSU and couldnt OC at all. then i got a new PSU and case and got everything put together and i ended up having to RMA my motherboard. 10 months later everything is back together. i have my CPU stable @ 4.2ghz (1.280v) and i got my GPU OC'd FINALLY!

here are numbers

1000mhz core @ 1174mv - this is the sweet spot for my GPU. it will do 1024 or 1050, but i jump up to 1.25-1.3v for this and the reference cooler isnt good enough for those voltages. from reading around it seems like 1000mhz core at 1.174v is a really good OC

1450mhz memory - my memory also seems to be doing well and above average.

maybe the reference design card is making the difference, i do have the version 1 XFX card.

my max temps are 70-74*C. (i crank my fans up to 60-65%, i dont mind the noise cause i will be shooting guns all the time on my games. idle fan is at 35%, so its silent)

UPDATE:

I think i might have to bump up to 1.184v or drop my mem to 1425 or so, stress testing with ATItool went smooth but Crysis WH crashes sometimes... (no BSOD or anything, win7 just says it "stopped working" and i can then reload the game) but i dont get any artifacts or anything... my CPU passed 20 loops on IBT @ 4.2ghz and my max CPU temp during crysis WH was 47*C.

i can play Crysis: WH at 30-40 fps. sometimes i dip into 27-29fps during an explosion but its still playable. i run 1680x1050 resolution and Enthusiast level details. not bad for a GPU i paid $150 for and a CPU i bought used for $105. the rest of the computer was built on an original budget of $500, 2 years ago

ill work on it a bit more later... for now i have a good starting point and i wanted to go to sleep 4 hrs ago lol!

Thats a really nice oc mate. I have 2xfx 5770's in crossfire @900/1300 and they eat any game I throw at them at 1920x1080. I would oc higher but i see no need in it for the time being.

Are they really running that high with the reference cooler?

Nothing to see here.

yea, the card is all stock except i swapped the factory thermal pad for some AS5 and cranked up the fan speed and started overclocking to the sky.

UPDATE:

1450 turned out to be my limit, so i backed down to 1425 on the memory. rock solid for over 1 hr of Crysis WH on enthusiast and 8mins of ATi tool artifact scanning

1000mhz core is still stable at 1.174v. ill probably leave it there cause i need a good jump in voltage to go to 1050mhz and that 50mhz jump isnt worth the price i pay in temps on the stock cooler. running this low of a voltage and still getting 1000mhz core is awesome.

i set a more aggressive fan curve on MSI afterburner and my max temps are now 69-70*C in Crysis: WH on Enthusiast.

really happy with this card, its running circles around my stock card's performance

the 5850 is basically 2x5770 in terms of the number of shader processors it has, so i would hope its faster.
