How do you "lock-in" your overclock on a Radeon?

[The Sauce]

it appears you have been clock blocked. 😀

LOL! Totally. I got the Radeon Bios Editor (RBE) v. 2.4 which allows voltage mods as well as modding all the power state clocks individually. I am playing around with the idea of swapping to the ASUS 5870 BIOS for some higher clocks so that I can keep the power saving features. Hell, it was only $269. What's the worst that could happen? (Don't answer that.)

Thanks for the tip HM. I think I have the BIOS mod bug, though. Can't stand being clock blocked. I tried disabling CCC earlier but did not reinstall Afterburner. Worth a try. Appreciate it.

You should use ATI Tray Tools , to lock in your OC . Find it at www.guru3d.com

ASUS bios + RBE is the professional clockers choice. Everything else is just a big clock block.

Here's 800 posts of modded bioses with all kinds of links and references if you need help:

Sauce you can use AMD gpuclocktool to crank it up to 1000mhz, also Afterburner with an edited config allows this as well. The asus bios will increase the CCC limits to 1200/1400 instead of 725/1125. The ASUS bios mashed up in RBE will give you whatever custom clockspeed & vgpu you want to boot with and run in all 5 clock modes (boot, idle, 2d, uvd, 3d). Thats the most difficult , but in the end it's a handsfree setup. Just boot and be running at the speeds you wish.

Say for instance your 5850 can do 1020/1250 @ 1.227v with fan @ 45%, and you've tested and found this to be stable and have reasonable temps. Well you can set the card to default to that instead of 725/1000 @ 1.08v w/ autofan. Then you can increase your shader & memory CCC slider limits to your liking for when you really want to benchmark, or do a suicide run.

Sold! I flashed the MSI BIOS. Gives me 1550/2250 in CCC. RBE has me pretty confused. I want to use it for volt mods, but I also see lots of borked BIOS/bluescreen posts in the thread on it so I am somewhat wary. I started a new thread on this. We can let this one die. Not a problem anymore. Thanks.

Sweet. Yah, the RBE 5xxx bios modding is still kind of hit-or-miss. Bagz just added 5000 support like 3 weeks ago. In time there should be some good bioses out. That MSI bios has crazy high CCC limits. Glad to hear you got it sorted out, cheers.

yep, I just tried Afterburner on mine and it goes right back down to CCC limits. Will have to play around with the RBE, but tis getting late...

EDIT: thanks for the resourceful link, editing Afterburner's config file seems to be a quick and dirty way out for now 🙂
