Has anyone had any luck overclocking a 5770 ? I have read a few professional reviews of 5770's being overclocked with good results but as far as the threads on Tom's it seems like it has not given any real world results. I have tried to overclock my own Vapor-x 5770 and it doesnt seem to be helping.

If you have seen good results can you please post your gpu settings and methods..

thanks.

Was about ti ask the same thing.

Really ooking foward for some working settings! :D

The 5770 is actually quite good at OCing. My buddy have an XFX and the gpu is stable at 950MHz without any voltage increase. I do not recall what his memory was but it was over 1300MHz. He used the ATI overdrive utility. I think he actually ran the ATI overclock tool,which i never use but seemed to work for him.

what are you using and also what are your settings.

cpu: phenom II 945 x4 3.0 ghz
psu: corsair 750hx
ram: 4gb gskill 1066mhz 5-5-5-15
os : win xp

gpu: sapphire vapor-x 5770 1 gb (860mhz core / 1200mhz memory is stock)
At stock settings I'm getting about 32 fps average in Crysis Warhammer at 1920x1080 on gamer settings no aa.
I'm using ati overdrive to OC. I tried raising it to 960 / 1400 like they did on this website.

,but after a few minutes of crysis at those settings I got a grey screen with vertical bars. I dont really remember how it affected my fps. I dropped the clocks to 900/ 1350 at that point I was just experimenting to see what would happen.
However my frame rates were lower than the stock settings.

I wonder if a bump in voltage would help, as far as heat I think it can handle it. The card runs really cool. About 30c at idle and 50c loaded.

What percentage is your fan running at? Mine at 50% slightly overclocked idle is about 41-43 C. What is your chassis?

At Idle my gpu fan runs at 40%. My case is a $20 no name midtower. It has two 120mm vents on the side though, one beside the gpu and one beside the cpu. Top mounted psu. and I have one 120mm case fan just under the psu running at 1200rpm.

You say your slightly overclocked? have you noticed any benefit for your clock settings over stock?? if so, can you share your gpu settings.

No GPU will overclock the same. I would start with just the GPU and start at 900MHz, run a few tests. Then maybe 925. You can also start from where you are at and go backwards. Go down to 950, then 925. Just find where it is stable. Sometimes you will be stable at lets say 950mhz, and everything is fine for months and a new game comes out and kills it. So you find yourself turning it down a little. It's alot of trial and error. Once you get your GPU clocked, work on your memory. Try 1300 and go from there.

MSI afterburner is a GREAT tool for the 5000 ATI cards. It's free and works with any brand. I use it soly for the temp, graphs, and OSD. It have Rivatuner components in it.

Hmm...That's pretty good. I have eight fans in my computer seven of which are 120mm. I should work on getting my heat down.

I have an XFX HD 5770 which clocked to 960mhz core and 1300mhz memory. I flashed the bios with an unlocked asus bios using atiflash, this enabled the card to have the ability to clock beyong 1ghz as the stock bios is locked to 960mhz. i used msi afterburner to overlclock initially but noticed that i couldn't get the voltage to set (i had ticked the boxes under 'safety properties' and altered the config file but the voltage shown on afterburner does not seem to alter the stock voltage).

In order to gain clocks above 960Mhz i had to increase the voltage so i used Sapphire TRIXX utility to overclock the graphics and this time the voltage settings worked.

I am currently on 990MHz core clock, 1370MHz memory clock with 1.225v Vcore.
Others have gone beyond 1GHz core clock and above 1400MHz on memory clock and upto 1.275 Vcore.

I noticed that i had only improve my fps by 5fps from stock with these settings on Kombuster 1280x720 benchmark. Current score 3208 with 51fps.

Hope that helps.

since im upgrading in few days ive doing alot of readup on what my current card (XFX 5770 XXX) has getting around the world as far as overclocks/results etc. My has been at 1000c/1460m @ 1.125v for the past 8 months rock solid on the stock EE air cooler.

must be a perfect cherry picked card, been very happy with it and its even beating every stock 5830 card ive come across.

here is a screenie of a heaven bench i just did. can't say i've ever seen a higher clocked core on the net yet stable 24/7 on stock voltage & cooling.
