*** Official Radeon HD5800 Series Overclocking Thread ***

gotta spread the word..

there's a "new" tool from sapphire called trixx for 68x0/69x0 cards that works on non reference 58x0 cards, can finally increase voltage :D !

saw this at tech power up, link for app:

Thanks :up:

Here is another on 11.2 cats

The third card will be on water at the beginning of next week. Not a good financial decision putting a FC waterblock on a 150 dollar card, but I love the 5850 reference cards.

Lil' late but I like this 5870:)

On water...

Anyone know what would be safe voltage levels to run a 5870 under water?

I was wondering which 1 GB 6950's are still Rev. 1 and unlockable.

Hey Guys,

im having a bit of trouble getting a fan profile increase using RBE.. ive changed the profile and reflashed the BIOS but it doesn't seem to change the fan speed at all, is there any way to change the fan speed (on the BIOS) and not through CCC .. im using this BIOS:

and just leaving the clocks all standard and just modifying the fan profile.. but its not sticking.. its just constantly stuck at 21% even under full load @ around 77 Degrees C.. if anyone could help would be much appreciated :-) Standard Reference 5870

Bump.. anyone?

So I see nobody responded. Oh well, I'll just edit this post.

I got an XFX 5870 stable at 1023 on the core @ 1.27v, and I got a stock amd board to 1000 stable at 1.27v. I chose 1.27 simply because it was the average of all the successful voltages for 1ghz and above.

running in crossfire means both cards run at 1ghz.

Bump.. anyone?

Very late to the party, but I just got a Sapphire 5870 Vapor-x for cheap. Unfortunately, vcore limit is 1.16v and there's no way I can raise it.

This is my highest stable overclock:

I find when I overclock the memory past 1280MHz my benchmarks go down. Core goes 945MHz max but I like to stay under the max overclock for a healthier life for my GPU ;)

Holy Necro thread Batman!:eek:

Hey thread necromancers are awesome :p:
