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(Oh and of course the checksum is no longer valid.)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... :mad:

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!:ROTF:

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... :shakes:

no it could be. It all depends on what else he's running in his system and what your respective ambient temperatures are

Use at your own risk!
Flashing your BIOS should void you of warranty

I've found this BIOS that overvolts the core up to 1.5v and the users say that you could overclock the core up to 900Mhz...
Quite a impressive try...

So now if you dare use it the file is below...

Watch out for the core temperature rise!!!

Go to this site and click on the FILE.01 located on the top right side of the article which is green and says 64.0KB on the right...
http://www.parkoz.com/zboard/view.ph...sc=asc&no=2517

Couldn't like the file directly... can anyone do that for me and even better if you can teach me how to...

Don't blame me if your video card is damaged...
Since I have a stock cooler not going to use it myself...
Just another info. for those who want to go to the extreme...

thats a korean webby right
interesting

so who dares to walk a path of a test pig

Depending on what price the 3870 comes back down to, I may or may not buy one and try the test.

Honestly this isn't like the first time anyone has done this, I mean plenty of people volt mod their boards and what not. As for the stock cooler, with 55nm, I wouldn't say it's a big deal, though if people really want they could always buy an hr03

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!

:rofl:

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!:clap:

The 1.5 (1.499) volt BIOS you mentioned is the same tech power up image changed the same way I changed it for 1.377V. (Only the six corresponding value modified to DB 05 = 1.499 decimal)
So IF the 1.377V BIOS worked, it will work too.
1.5 volt... don't think it is air cooling territory, but who knows.

apparently from a google search I got the (last strain) bc08 means rated for 1.2ghz, the bc09 in the 1gb r600 is rated for 2.2ghz. There apparently are bc07 and bc06 ICs that are rated for 1.4ghz and 1.6ghz respectively, but I don't think those would come into production due to their cost and where ati needs to place the 3870

K4U52324QE-BC08
Rated: 1200 MHz (0.83ns)

No reason why you can't run this on the stock cooler. You'll want to keep it at 100% and make sure you have low ambient temps.

hi all

i'm on water and i tryed upping my volts to 1,5v but it didnt give me any higer stable oc (862mhz 3dmark06)
but now that i see this one has 1,499 maby it's a magic number needed for it to work
who knows, any how i'm testing

I've tried both the supposingly 1.377v and 1.499v BIOS volt mod but seems I'm getting a blank screen with both of them...

Can anyone tell me what might be wrong?
Giving higher volts doesn't necessarily mean that it will consume more energy(watt) does it?

Also why isn't there an hardware ID in the volt modded BIOSes?

I tried both BIOS but they are not overclocked so must work fine even with stock cooler but might not when overclocked due to temperature...

But again I'm getting blank screen with the 1.377v and 1.499v BIOS...

By the way I've used and modified an adaptor cable to connect my stock cooler power supply line to the mainboard to save a tiny bit of energy consumption (about 5watt? I guess) that comes from the 6 pin 12v VGA power supply cable coming out from the PSU.

This didn't help much...

For now I'm using the BIOS posted on the TechPowerUP Database file and can see after running few minutes of ATITool artifact scan that it can be stabilized only up to GPU@840Mhz and MEM@1200MHz...

Really wanted to reach atleast 850Mhz but artifacts shows up though ATITool doesn't say it is an artifact I can see a few yellow dots appearing and disappering on the fur rendering...

Can anyone tell me why I can't use the volt modded BIOS?
By the way I've used the correct command which is:
a:\atiflash -p 0 -f biosname.bin
loaded up the fan at 100% and flashed...
reboot and blank...
under darkness I've type the commands to return to a working BIOS...

no magic number's there i'm afraid

so time to get to the bottom of this
has anyone here done a complete 3dmark06 run with an oc higer than 862mhz on a pci-e 1.0 slot?

Heres a run I did right before I left for Thanksgiving holiday
http://service.futuremark.com/compare?3dm06=3849346
I believe clocks were at 877/1314 , with my E4300 @ 3.54. If you try 3DMarking with an unstable clock, you'll actually get a lower score due to dropped frames ..... at least that was what I experienced when I ran it at 905 MHz.

thanks for clearing that up
i guess my card just is at it's limit then

hey guys since the Msi OC bios is in mkvtech

can u check with ure hex editor
to see the difference
and also the voltages

will there ever be a bios editor for this card??
nitbitor is damn easy for nvidia.

the problem with the fixed bios was
it was unstable

during the second test of 877 core
the flying wisp thingy
it will fail for no reason
even when ati tools artifact scanning shows its okay.

unstable bios?

Man, what the hell is with this, ati unleashes a monster card that was supposed to oc way farther than the r600 because of the 55nm die and then they cap it just so they still have a decent high end

The MSI OC BIOS power state table shows 800 MHz for 3D and stock Mem and Voltage.
