RBE - General information and discussion

[MilkyWay]

probly but i dont know why youd want to? it might change the clock speeds but you be as well just overclocking in that case

 

[btarunr]

Watch out. I don't think the memory timings match.

im asking because i want a bios that as 1.20v and still be able to use overdrive. i know RBE can modify my bios but it stops overdrive from working

Why don't you just use the method one overdrive hack of RBE? Will make any 4850 to do overdrive up to 800 MHz.

but if i change the voltage of the 3d clocks (03, 09) to 1.20v, it stops overdrive from working

Then keep it. Using Overdrive, the PowerPlay settings won't kick in anyway.

In my bios,the vgpu is modified to 1.158,and overdrive works fine,card is fine ocing to 750 core too with riva tuner so the voltage must be enough.I run it at 700/1100 24/7 which is fine for all my games.

can u send me your bios or do a screenshot?

Here is all i have modified with rbe.

Heres my cat8.8 pics

I have attached my bios.

4870 PowerPlay and RBE 1.14

Dear all,

I recently upgraded from a 3870 to a 4870. I have had some experience with flashing BIOS on my HIS 3870 (for Fan Fix purposes).

The 4870 I have bought is from Force3D (I think they are the owned by Inno3D) with their non-reference DHT-Freezer Cooler http://www.force3d.com/press/13_8_08_dht.html

Due to the non-reference cooler, the fan settings in the BIOS are very different from reference cards/BIOS. I am more interested in lowering the 2d Clock speeds from 500Mhz to 300Mhz like the 3870. But before trying that, I want to know if its even possible or advisable with 4870. Presently 2D clocks are set at 500Mhz with same 1.263V for 2d and 3d clocks (no other clocks are available in the lower left bottom corner of RBE screen, so I assume my card only supports one voltage (as explained in the RBE tutorial, which I have read of course before posting).

So can I change the 2D clocks to 300Mhz and would it save power in idle mode compared to 500Mhz.

 

[VuurVOS]

It doesn't save any thing. You realy must do a supreme powerplay fixed and lower the voltages to 1.083v in 2d mode. The best thing you can do to save power is underclocking the memory, but this will cause flikkering on the screen when switchen betweens stages if you edit the bios

The best solution for this is ATT auto overclocking. In 2D mode you set the ram on 200mhz (some bioses need a higher ram speed!) and in 3d mode you let the card on the normal speeds. With auto overclocking the card will automatic switch for you to the 3d profile with higher ram clocks.

 

[ernstblaauw]

I have a Sapphire HD4850. I really love to enable PowerPlay, but the option is greyed out. So, hereby I attach my BIOS so you can maybe enable PowerPlay for this card in the next version? I hope this is helpful to you .

Catalyst won't recognize card after flash

I use RBE and winflash to flash a ATI HD 2400 pro card. The problem is although flash went smoothly, the card with new bios won't be recognized by catalyst driver anymore. No matter how small and insignificant changes I made to the bios.

My question is : is it ture that certain card just can't be tweaked, maybe some kind of builtin check against it.

I would like to know more facts before spending more time, especially if it's something may not be possible to do.

Thanks.

Did you also tried a older catlyst driver ? Which type of changes did you make? Can you post a copy of the bios?

 

[DaveL]

I was using the latest CCC (8.9). I just tried 8.1 and no luck. Also tried ATIFlash instead of ATIWinFlash and result is the same.

I'm pretty much convinced that certain card like mine cannot be flashed or it will not be recognized by driver.

Both original and modified bios are in the zip file. The only change of the new bios is a slight increase (110MHz -> 120MHz) of one of the clock speed.

I think I found the problem. RBE has change other settings alswell. The bios has a look up table for the fan speeds. When RBE detects a look up table it does automatically a fix/patch.

VuurVOS, thanks for looking into it.

Just curious, you know why RBE is doing this fix to the lookup table? I would assume it's a necessary fix for something. If that's the case, too bad my card doesn't like this table to be modified.

Why RBE is doing this? It was necessary fix for the hd3800 series, otherwise the fan lookup table didn't work like expected.

The bios in the attachment of this post has a increased gpu value in clock 01. I increased it to 120 mhz.

Hey folks, has anyone had problems with "CheckValid" error msg? If yes, which BIOSes were you trying to feed into RBE? My Palit HD3870 (DDR3) BIOS gets a "kick out the door" as a "non-ATi". ComputerBase BIOS Editor opens it fine, but it has too few features.

 

[Martin.v.r]

this Is not a 3870x2 TOP bios,but a org:mod bios to BAGZZlash
but is ther a tool to edit rbe.exe fil to a higher oc in ccc ? no error whit 945 both gpu, run super to all 3D-mark test 01/03/05/06 I am on watercooling.

I have a Palit HD3850 Super (DDR3) and am experiencing the same problem

Please post your BIOS so I can check if the adjustment I've implemented for RBE v1.16 kicks in here as well.

 

[Martin.v.r]

here is the 3870x2 bios,there can run 945/1044 on Watercooling. 851/945/954/1100
hope you can lock it up a little more on gpu.. to 9XX

 

[Nrby]

Here is the Palit HD3850 Super (DDR3) Bios ... I believe it's default ... but I have problems controlling the fan speed ... in fact I can't control it at all it's at 100% all the time ... and that's the reason I am trying to edit some settings from the Bios

Yep, works with RBE v1.16.
Expect it soon!
