4870 ASUS TOP BIOS (upto 900MHz in CCC)

[STaRGaZeR]

I can confirm that this installs and runs fine on the VisionTek 4870. I'll report back once I'm done testing for my max overclock (stock volts on water)

EDIT: Appears to max out about 850/1100. I'm using an MCW60 and Enzotech copper sinks on the RAM + mosfets + anything else that got hot (that long thing gets DAMN HOT!)

I'm using a Fuzion GPU block, 30ºC idle 33ºC full load. With the original BIOS it maxed out at 870-880, with this one I'm rock stable in games at 890 stock volts. Artifact free in ATITool is about 860-865. Temps are very important with this card, with the stock cooler the max was 820 or so. I'm also using the red plate where the stock cooler is attached to cool the RAM and the mosfets, no need for more. In fact I think this red thing is more efficient dissipating heat from the mosfets than the Enzotechs, but who knows.

BTW Overdrive is so much better than AMD GPU Tool/BIOS flashing for changing the clocks

didnt work well when I tried games, got white snow and artifacts, flashed back to previous modded bios, and the white snow was gone.

This bios works like a charm. It also lets me overclock ~15 more mhz without artifacting.

I idle at around 30-32°C and load at 35-37°C. I seem to get minor artifacts on the desktop (when I move a window it leaves a few black and white dots in random spaces where I moved the window over). I get no artifacts in 3DMark06 or Furmark and I'll be testing out Crysis in a few minutes. Hopefully a driver update will fix the overclock limit and its not just a bad card for overclocking.

Anyone flashed a sapphire with this bios ? I got one card and it has qimonda mems, maybe it should work then ?

Yes I flash my sapphire,no problem work good but clock still is the same.
830/4400 no volt mod.

Hopefully a driver update will fix the overclock limit and its not just a bad card for overclocking.

If you mean the CCC MHz limit, the cap is in the BIOS. New drivers won't help here. RBE is able to read the limits, but not to modify the values. I hope in future versions we'll get that feature.

What I meant was why my GPU was clocking so much lower than what you achieved. I was hoping that using a different driver (I was using tweakforce's modded 8.6 drivers) would yield better overclocking results.

Sweet that'l make things easier. I've got a GeCube 4870 so i'll let you guys know how it goes!

I highly doubt that, but heh, try it and good luck. Use the officials Cat8.7, awesome drivers, huge perfomance improvements in some games.

did anyone try this on gigabyte 4870 model?

if not, will let you know if it works later on in the afternoon

[gundamit]

FYI - The cards I flashed were from Palit - the frog guys.

How is the fan profile at idle? The default goes up and down a bit which is annoying. I would prefer it to be a bit louder and not go up/down all the time at idle. At load it does not really matter as then there is usually a game running with louder sounds anyway.

I don't see why it wouldnt work.
I have a gigabyte too. Will be trying this one tomorrow.

[purecain]

Purecain, So this bios not only allows further overclocking in CCC but it also helps overclock better than the stock bios?

i would say that your oc is going to vary greatly... as some of us will have better core's than others...

i suppose its the same as with any cpu... you never know how lucky you are going to be with it....

i think everyone will gain 20mhz though minimum....

I would say thats a pretty good guess. I have gained ~15mhz on the core. I am going to try the XOC BE bios when I get home to see if it helps too.

Flashed my Club3D. Works fine.

[noobzed]

but what are the temperature, on IDLE under desktop for example, and in 3D stress, is it like the old bios ?
( 80°c IDLE and 90°c LOAD :/ )

Edit: with stock cooling I mean

[highspeed]

Great, thanks. Furmark stable as it comes

Flashed my Club3D 4870, without probs from USB disk. If you dont know how to do it just download this, easy as hell:

[M-XXXX]

Could someone write the whole procedure (which files and where to save them)? Last time I flash was X800 GTO2 and it was kind of different

my fans idle at 30%. they stay at that speed until the GPU's go over 60°, then they start to speed up. i haven't checked the percentage yet, but they will go up to 3200 RPM under load, depending on how hot they get (it's quieter than 45%). i played CoD4 in a cool room and my GPU's stayed at 60° the whole time. i played GRID in a hot room and they got up to 72°. that's all i know so far. the fan profile is great though.

[golfjam]

Just flashed my His HD4870. Works perfectly and runs cool. Thank you so much!!!!

[Alcibiades]

Sweet that'l make things easier. I've got a GeCube 4870 so i'll let you guys know how it goes!

I've installed it on my GeCube 4870 and it runs no problem
Have a bit of instability now after upgd to 8.7 cat
or was it the flash?
or both??
anyways my core is mediocre doin 800-815 before artichocking, stock no hard mods
even with ddr5 at 900, 815 core stable is max for me

waiting for accelero twin turbo to be released anyday now.
but im sure theres no probs with temp just needs more juice in the core,
so would like to hard mod too, anyone in sydney do this for a fee?

Runs ok on my Asus 4870 "vanilla" edition. But nothing gained, 880 core maxed out I guess with stock voltage.

[MoF]

So. Now that I had it installed, I tried to revert back to my backed up club3d BIOS. And it didn't work (blank screen). Nothing seemed to help, so I installed a spare 8600GT on the first PCI-e slot and the 4870 on the second in order to gain picture, and I succeeded in booting to dos with it. Then with atiflash I checked the current bios version of my 4870 and it sure was the Club3D one. So I figured maybe I'll try to reinstall it to see if it helps and I noticed that the Asus 4870 TOP BIOS was twice as large as my Club3D original backup. So my guess was that the original backup didn't quite succeed. I reflashed the Asus 4870 TOP BIOS on the card and it came back alive.

But I would like to have the original BIOS just in case I need it. And since it seems my backup isn't worth , is there any other place I can get that BIOS from?

[SNiiPE_DoGG]

yeah you needed to use GPU-z .26 not .25 .25 doesn't extract the right size bios


heres my top bios results, although it has less to do with the TOP bios and more to do with my voltmod
