Unleash the Gladiator (RV670): 862MHz GPU Clock Limit Fixed

[tiger8312]

You should get 1.377 Vcore with this BIOS image.
(I don't have a 3870, so i cant verify)
Is someone brave enough to try out?
Use at your own risk.
(Oh and of course the checksum is no longer valid.)

I've tried this BIOS which is suppose to increase vcore to 1.377v...
After flashing I've turned off the computer and unplugged the power cable and rebooted...
But guess what?
I've got a blank screen....
So I've booted up with blank screen and got to the menu in my bootcd with the flashing util.
and flashed again with the BIOS that was posted on the TechPowerUp BIOS database and rebooted...
Worked my way out through the blank screen... (pretty scary...)

Well now that I've reflashed the BIOS it works fine...

Did you use the right command line? i didn't have that problem when i flashed,

Use:

atiflash -p 0 -f biosname.bin

there is nothing wrong with my command since I've used the same one as above...

Okay guys,

With the 1.377v bios, I was able to achieve 855core, 1301mem. Temps at load don't go past 58C, Fan fixed at 68% at all times.

I'm going to take off those thermal pads and apply some real AS5 to the core now. I just know the temps are gonna drop drastically after doing so.

After that, i'm going to aim for more core, maybe more mem.

I'll keep you guys updated!

even with the fan fixed at 68% how can you achieve a temperature of 58C on load?
Mine with the originally posted BIOS shows about 60~62 core@850 and stock MEM speed with fan at 70% fixed....

You even applied the 1.377v BIOS!!! there should be a bit of a temperature rise...
The temperature doesn't seem reasonable to me at all considering the BIOS, overclocking and cooling you have in which the cooling is stock...

I have the antec nine hundred case dude, 5x120mm fans going at full 130CFM plus the 200mm beast fan at the top. if you stick your hand in my case, it's like a wind tunnel.

UPDATE:

okay I pasted the PCB and the RAM BUT there was a gap between the ram and the copper heatsinks! so that was for nothing...what a waste of AS5. I put the "bubble gum" thermal pads back on...repasted core with AS5, now my idle temp is 31C where as before, it was 36-37C.

I am going to attempt the 1.5v Bios, and aim for higher core!

UPDATE:

I forgot to mention one thing, and it's huge!

While I took off the ram heatsink, i marked down the ram's model#.

For the Sapphire HD 3870 512mb the model is:

Samsung
K4U52324QE-BC08

Now we can find out what frequency they are actually rated for! w00p!

Okay I just flashed to the 1.5v bios. Idle temps with 70% fan is 35C with AS5 Pasted might i remind you.

Going to do some benchies now, i'll be back soon!
