Use the latest RivaTuner to get higher clocks

Also, GPU clocks work in blocks. For instance, my 8800Ultra increases in blocks of 27Mhz so if i'm running 648 on the core or 655, it doesn't matter, because the core will only work at 648. I have to incresae to 675 to see the next jump in MHz to 675 etc.

So hit another 13Mhz and you should be at a new 880+ value.

I'm trying rivatuner at the moment and i've put it up to 900 within the clocking utility but it show 877 on hardware monitor and gpu-z still?

I dont think it works with the hd 3870?

Aha okey doke i getcha, just in the process :D seems to be working :D

ATITool doesnt support RV670, i tried it yesterday
Rivatuner 2.06 does though, so please try that since you might be able to go above 885, which seems to be the Overdrive limit

I put it up to 902, in riva tuner, tried proxycon and it crashed , GPU-Z shows :

Now it needs volts :D

Time for more voltage it looks like =]
ty for sharing your results, hopefully we'll get some updates from W1z on ATITool, or maybe a bios mod to up the 3D Voltage

Are those memory values stock? And how's the heat at 902 core?

Yeh stock memory, it runs at about 60C with 100% fan at load at 900MHZ

wow, big temperature increase from only a slight increase in clockspeed. You said you were getting 51C at 872MHz earlier

I'm just retesting now, i think it showed so high because it crashed out

Yeh i just retested at 905 with 100% fan speed, for the 30 secs it was on proxycon it shows 53C but i cant say that's deinifitely the figure as it crashed.

if it crashes very early, whatever temperature you see is not the load temperature. Its possibly a good deal higher because it takes a longer time before you can really tell what your load temperature is

Sorry but do you guys use Winflash or Atiflas to flash the new bios?

And if Im on crossfire i will be able to select which card to flash to right?

Apologies as I have never flashed a VGA bios before.

If I was you I would only have one card in the system before attempting to flash. The tool can be found by following the links earlier in this thread

The link has two tools, ATI Flash and WinFlash.

So either would work?

I think they used WinTool? Not sure, maybe martin can confirm

I used ATIFLASH, i removed all current display drivers and catalyst.
Used floppy to boot to DOS and saved the old bios to the floppy disk "a:\atiflash -s 0 oldHD3870bios.bin".

Went back into windows and transferred the bios to another computer for a hard backup.

Then i booted back into DOS and "a:\atiflash -p 0 -f HD3870new.bin" (i had renamed the bios from TechPU so as to make it easier in DOS).

I then shut off the power and did a hard reset by removing the main power lead and then replacing it.

This worked perfectly for me anyway and i personally don't like flashing stuff through windows as its a bit volatile and not very easy to rectify

It works perfectly!
I flashed both cards simultaneously using ATIFlash.

Here is my TOP (hotter) card running in single mode just to find max clocks....

Attachment 67600
Fan set @55% (reasonably quiet, like 36% for HD2900), room temps around 22C-25C...

This seems to be max on my first card though!

Now I need to try my BOTTOM (colder) card :)

Here it is:
Attachment 67602

Lets find max GPU clock on this one :D

Thanks for the results. From the few other results I've seen so far, it seems like everyone else is also hitting 877.

So the question comes to be askin', is it still a weird divider or are these things that starving for volts that badly? I ask because with the exact same clocks from the users I've seen so far, we're obviously seeing another wall caused by neither temp nor architecture.

If it's not the divider (again), then I hope to see some v-mod results after our resident bios and software voltage changing experts figure it out. :)

Yeah...So apparently it was at it's top before, and this is just a fixed divider (ie different ratio/smaller increments) to squeeze out a few extra mhz? Hmm.
