** Official ATI 5770 Thread **

well its a big improvement over my 4890 (just tried hawx and its smooth as silk now), and i think thats a tad better than your 216 last i checked :p, the corsair 750 is fine im using it myself, it probably can handle dual of anything tbh
 
aaaahhhh so you have to use the MSI Afterburner tool to increase volt?

I was using CCC and it was pants.

My asus is at:

1225 mV
1000 mhz clock
1300 mhz mem

Think I can get more out of the memory! gonna try 1350
 
Anyone notice a driver crash as soon as resuming from hibernate ? Or is it just me (this is under win7 x64) ?

sweet got a stable 1000/1350 on my Asus card.

Running the Stalker DX11 benchmark means it stable? That a good assumption?

Run Furmark stability test for 15 mins or more. Check for artifacts or digital snow whilst its running and especially at the end of the test.

If games hard lock after a while and only a forced reboot cures it then back your ram off.

Mine initially seemed fine at similar clocks to yours. 10 mins of Furmark and 20 mins of L4D2 (Hard lock.) proved me wrong.

yep I got a black screen hard lock last night on l4d2, I have upped the fan to 60% and dropped the memory down to 1300, will test more tonight.
 
I finally got around to changing the thermal paste on my 5770's. Sure enough they're at least 10c cooler under load than before and they take forever to get from 30 to 65c where before it was instant when running furmark.

It makes you wonder why they do such a pathetic job in the factory. A clever board partner could make a bit of money out of these little tweaks. I'm now nicely OC'd and these things are trampling all over the illusive 5870. WELL HAPPY!!!!!!!!!!!!!!!
 
yeah that was the 1st thing I did when i got mine, i just installed the asus bios on both and powerplay is working great now, both kick down when idle to 157/300


before 1st card was 274/975 and 2nd card 157/300, now both kick in fine (thought aero desktop kept the 1st one at higher powerplay state but obviously wrong)

also i had to remove the drivers and reinstall them, anything 3d complained that i had no 3d accelerators etc.. a little scary moment lol

installed the asus smart-doctor and well chuffed :D good stuff

cheers
 
...heres the guide to voiding your warranty:

Another way to eliminate these over clocking limitations is to flash the bios of your 5770 to that of the Asus HD5770 Voltage Tweaker Edition.. Please note that doing so will surely void your warranty and could very likely render your card inoperable!! Follow at your own risk...

Below is a detailed guide to flashing you bios.

**Please note again, you take full responsibility for doing this**

Lets start at what you need..

* Any Flash drive or USB bootable device such as external hard drives will do
* HP USB Disk Storage Format Tool
* The Boot Files (Extract them)
* Atiflash
* The Unlocked Bios (Extract it and rename it to something like unlock.bin

Start with installing the HP USB Disk Storage Format Tool.

* Select the Device you plan to use and choose FAT32 as the File System
* Tick the box "Create a DOS startup disk" and select the option "using DOS system files located at" then browse to the extracted boot files you downloaded.

Start the prosess.

When it's done you will have a bootable USB device, all you have to do now is copy the Atiflash.exe and unlock.bin to the root of your bootable device and reboot your computer.

See to it that your bios points to this device as the First Boot Device and once it booted to DOS just type:

atiflash -f -p 0 unlock.bin

Once finished it will tell you to restart the computer to continue, just press Ctrl + Alt + Delete

If you have 2 cards in crossfire, remove one and flash one at a time, making sure the one being flashed id in the top most pci-e slot

Enjoy unlocked overclocking...

reinstall drivers in windows and its all good :)

didnt see it posted before so here it is, thanks goes out to keenan
 
to be honest i didnt really worry as i have 2 cards so i can recover from a bad flash if needs be. unless you do something silly like poke a screwdriver at it whist flashing then it should go smoothly. besides it takes like 2 seconds to flash too

but dont listen to me :p (or blame me i mean ;))

my idle temps are 43 degs & 47 degs for card 2 (both at 1247 rpms)
 
bought my 5770 a day or so before they declared that all of the 5770's would come with a dirt2 voucher. I emailed fatboy with no reply :( what to do?, webnote?
 
I think Fatboy has been doing his best to keep everyone happy. Try him again but if nothing happens it's fair play isn't it? I mean you don't go and buy a sofa for 500 quid in december and then complain in january that they haven't sent you a cheque for the january sale discount.

Is it a bad idea to try and flash a 5750 card with a 5770 bios?

If it does not work i can always flash it back? right?
Click to expand...

that's asking for trouble to be honest, I've not seen any reports of anyone flashing a 5750 > 5770, its not as if your going to magically get 80 streams & 4 texture units :p, best bet is to flash with the asus 5750 bios if it allows you to unlock and clock higher

flashing it with the wrong bios might kill it and you might have no way of force flashing it back
