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

[madriddistas]

1)I'm planning on Overclocking my future HD5870 Powercolor reference card (Haven't arrived yet) and my plan is to flash Asus bios and tweak the voltage and OC the card to 1100/1250. is it possible to do this on stock cooler?

2)But, is flashing Asus Bios is a real Hassle? Or is it just an easy task? Sorry haven't tried flashing GPU bios before.

3)I've heard of cards died by tweaking voltage and all, but is it possible to flash back the original Bios after the card died?

4)Or are there any possible situation that will fail me to flash the original Bios back?

Thanks in advance.

My 5870 arived and I'm pleased with the Crysis result



Roughly 5-8fps faster than 4870x2

Is it nomral that the card starts to artifact around at 80c in furmark?

Good result... I think the 10.3 drivers must give it a boost, just finally downloaded Crysis and installed it... Got 41FPS average with those settings but without the 2x AF with a lower min FPS but 52 highest...

I got 50.3FPS Avg with Veryhigh without AA.

I can't post any pictures because i'm on vacation until 13th April.

Compared to overclocked GTX295 with i7 4Ghz in Crysis bench 1680x1050 veryhigh, the GTX295 leaded by with 56.9FPS avg, followed by 5870 1Ghz with 50.3 fps avg.


This volt thirsty sucker needs 1.35v to be rock stable at 1Ghz on GPU tool artifact scanner.
