Unlocked overdrive and now card cant be recognized by Vista in Catalyst 8.8 WHQL, back to original bios and it worked.... pretty strange
Info for Bagzzlash! And others as well :)
LINK TO THE POST with some new BIOS from ATi, with some interesting stuff in it. I'm at work so can't test it, but read the post text and it will sound interesting. Specialy if this is really from ATI and not from Diamond (guy did say ATI explicitly, so should be official).
It has unlocked CCC overdrive, and seems they did something to voltages as well. You'll get exe file that auto-flashes the card, but you can extract it (I've done it with PowerArchiver, but probably WinRAR will work too), and you'll get the files. "4870-128Kb512MBOC795-1100MHz.sb" can be opened in RBE no problem and shows this:
BIOS DATE: 08/13/08 13:01
VERSION: 113-BA0701-100
ATOMBIOS VERSION: ATOMBIOSBK-ATI VER011.003.000.001.029254
500/1100/1,276V 2D
795/1100/1,276V 3D
Note - higher voltage! As soon as I get home I'll flash it, try it, and see if it really ups the volts, and if you can use lower volts as well.
Also, 990/1250 is upper OC limit in CCC.
This should be official ATI driver for boards based on reference design, so start flashing ppl! :)
Btw, I have posted or will be posting this in other threads too, as it is VERY interesting info, and I guess as many people know about it and test it - the better ;)
Cya all!
EDIT: 4870 cards bios, ofcourse..
EDIT2: I'm home now, and can confirm that voltages are up a bit, roughly +0,02V under load with card running on 795/1100 (vs stock bios and 790/1100 OC). Lowering voltage does not work, and you can't do the "low volt tweak" with RBE 1.13 (you can, but it won't actually change voltage once you flash it). Also, you do get unlocked Overdrive which works with 8.8 Cat's

Try with this new BIOS; it is mostly stock BIOS with unlocked Overdrive and a very little bit increased voltages. Report here if it works, I've tried only in XP so far!Quote:

RBE v1.14 is available now!
Here are the new things:
v1.14
- Fixed bug with method one overdrive hack not working. Should run fine now.
- Added fan control for 4870 X2. Completely new controller chip, was a big pain in the ass to code... :-/
- Made spin up fix, powerplay functionality and voltage decrease in the one-click update for 4xx0 cards seperately selectable.
- Fixed WinFlash check sum correction bug.
- Added and fixed a lot of small things. Too many and too minor to mention all... :-)
Please tell me your opinion about everything! :)
going to try it today, hope overdrive unlock method still working w/ newer driversQuote:

@bagzzlash - tnx for a new version, will try out right away :)
EDIT: Well, my overdrive is 990/1200 and I have Cat 8.8. I hope it will work fine for your 4850 as well! All other functions seem to work as well

Yes, first method, through that new dropdown menu.. OK, you need 900, and it's a bit lower than that in first method for 4850's :( But than you should try Ati tray tools (new beta, see on guru3d forum), it has auto-clocking which alows you to set any clocks speeds, and if you make 2 profiles (2d and 3d) you'll be fine even if RBE or BIOS isn't unlocked and tweaked.
Btw, if you know your max, why don't you just edit BIOS and leave 2d clocks as they are, and 3d clocks to the 900/2150 that you have..?
When I tried that w/ RBE 1.13 Catalyst 8.8 said adapter is missing, only original bios worked..Quote:

When you click on text box of any clock/voltage you'll get info in the box on the bottom for what is that setting.. You'll notice :)

3 colors for each one, i dont exactly know which is the right
When you click it, the right description gets highlited below.Quote:

RBE v1.15 is ready for download!
That's the changes:
v1.15
- Fixed bug causing an error message on loading several BIOSes (small ones like several 3870 X2 BIOSes).
- Added remote control feature for WinFlash to acquire and flash BIOSes from within RBE. Will be included in the tutorial soon.
- Superior PowerPlay should be available for more 4870 BIOSes now.
- Added link to the tutorial in the menu bar. (Info... Tutorial on how to use RBE (websource)...)
- Added display for the card's internal voltage table (it's in the clock settings tab).
- Fixed a bug causing the device ID being written incorrectly if it's changed in rare cases. Coded this very drunk, there might be bugs... :-/
- Added some nice method one hack signatures (4850, 4870 X2).
- Added a feature for method one overdrive hack signature saving and loading.
Have fun using it and please be sure to make extensive use of the signatures exchanging thread!
I tried to change Voltages on an Asus 4850 using RBE v1.15 with no luck, card works on 2d (DOS) but hangs when booting OS.
The card is non reference, has the Glaciator cooler and the 3 phase design used in some Asus 4850 Top cards, also CCC limit for GPU is 800 in the original BIOS.
Is this BIOS unmodable for VGPU?
