Here is my modded bios everything looks fine. I dont understand why it doesnt work. http://myfreefilehosting.com/f/c5914d232b_0.13MB

How did you flash? ATIWinflash or ATIflash. And which version did you use? Did you forced the flash? And did it also happend with a reflash of the "evil" modded bios?

I think you did it under Windows. It can cause a corrupt flash because other program's are still running in the background. With dos you dont have that problem.

 

[The Haunted]

I always flash with the latest atiflash version in dos, never had any problems flashing.
I just modified my bios with rbe and when i flash with it it display something like this:
model version (previous):9440
model version(current):
bios version (previous):whatever...
bios version (current):

This only happen with a bios that i modified myself as i wanted to change the 2d mode clock to see if i could get a more stable overclock.
Look like the bios is missing information but everything seem fine when i reopen it with rbe...
( i saved it as a .rom)
oh and i use --> atiflash -p -f 0 name.rom <-- command tp bypass the ssid check (cant flash a 4870 without this)

 

[VuurVOS]

I check it and you right but there is some stuff changed after creating the bios. I tried to recreate your modded bios with a clean top bios of asus. During flashing I saw the same thing. After the flash I did directly a recovery. With RBE I saw some changes at the Fan settings. The changes are
-Tmin -> 0
-PWM ramp on -> activated
-PWM ramp (%) -> 1
-hysteresis(%) -> 0
-Tmin hysteresis -> 0

I know why this happend. For the HD3800 serie you must hack the fan controls when using the lookup table. RBE is doing this automaticaly when selecting lookup table.

But I think this is not needed anymore because the asus hd4870 top bios already has a look up table of its own and it will proberly work on the other hd48** aswell

I also use the look up table for my hd4870 bios (113-B50701-105) but they didn't cause any problems. The only difrents with the fan control with the asus is
- a higher Spin up cycle
- a higher Tmin (also anonther Tslope(%) but thats automaticaly calculated by RBE).

Until BAGZZlash is coming back from holiday, I suggest you use the 113-B50701-105 (hd4870 beta) bios or the Diamond HD4870 XOC (overclock bios which is far beter than the top)

Low 3DMark 06 Scores [4850]

Hi guys

I'm new to the forums and the 4850 card.

I've just bought a Sapphire 4850 Toxic card, and overclocked it using RBE (great tool!).

But I think I'm getting low 3DMark scores (please see attached screen shot)

System Info:
CPU = AMD Dual Core 3800+ (2.2GHz)
Mem = 3 GB DDR (400)
G-Card = Sapphire 4850 Toxic
Mobo = Gigabyte GA-K8NXP-SLI

In GPU-Z I see the new clock speeds (720/1200) so I know the overclock has worked which does get me an increased score in 3DMark over the default clock settings, but I think they are both low compared to others I've seen (I know that my CPU and mem are dated)

I've tried both 8.6 and 8.7 drivers, tried the AMD Clocking Tool (uninstalled now)

3Dmark settings are all default.

Please see screen shot with more details (RBE, GPU-Z, 3Dmark)

Thanks for your help in advance.

Why arent you running all the tests? I can only see an SM2 score there. All 3 scores combine (not additively) to make an overall score.

After you do, you should expect a score around ~9k. The CPU becomes a huge bottleneck (especially yours) in 3dmark06, as well as the hd4k cards generally not performing well in 3dmark06.

 

[ShadowFold]

What is your full 3dmark score? And do games run fine? The AMD X2 is a pretty big bottleneck tho..

 

[DOM]

lol you need to run the full test

Welcome to TPU

 

[axel 66]

Thanks for the quick relies guys

Ah, sorry I just done the top two tests, the attached screen shot is the complete test.

Basically I'm the the proccess of updating my machine (new mobo, Intell CPU, DDR2 mem)

Are these scores ok going on my system stats?

Thanks for your help

Axel 66

 

[ShadowFold]

That score seems normal for your setup. The X2 is a huge bottleneck and the 4000's werent as good at 3dmark as the older ATi's.

Thats good then, should get betterr scores once new PC is built.

And yes games seem to run like a dream compared to my 7600 GT

Thanks again

It's your CPU thats giving you the bottleneck. Overclock it some and you will see those scores skyrocket.

I got 11700 with my card stock and chip at 3.2ghz for comparison.

Sweet, the CPU is overclocked a bit. I will try and OC it a bit more. I have a aftermarket cooler so think I could get a bit more out of it.

Is that 3.2ghz out of the same CPU as mine (3800+)?

Thanks

How to edit bios 4850?

I'm having Sapphire 4850, and i want to edit my bios like as bios of Sapphire 4850 Toxic. So, i used RBE 1.13.
After searching on internet, i get some informations:
-Clock info 00: clock when boot
-Clock info 01,02,03: clock when use Powerplay with low,middle,high level
-Clock info 04,05,06: clock UVD
-Clock info 07,08,09: standard settings
---> Are they right?
I've edited bios with clock info 675/1100, and saved it. Then I opened that bios and saw the Standard Clock (in Additional features) didn't change (still 625/993) although Clock info changed(675/1100).
How can i change the Standard Clock?
Second, how do i find out Voltage suitable for clock 675/1100? 1.12V is OK?
And finally, will my vga be stable with clock 675/1100?
Thanks for reading.

 

[gareth170]

i think Clock 01,02,03 and 07,08,09: are both use Powerplay but the high levels is the 3d clocks

 

[tomcug]

I think this should help you:

I don't know if your card'll be stable at 675/1100MHz. It depends on your card. Some need lower voltage, some need higher voltage to reach that frequency. Also, you can't change these clocks in Additional features, because they're only Overdrive settings, your card'll be running at speeds you'll set in Clock settings.

Ive used RBE to edit the bios of my 4870 but the software is very picky with what I do with it.

 

[platinumyahoo]

anyone want to edit my bios to increase CCC limit?

Im not sure what to do to increase CCC limits, and i need my fan to go to max. anyone want to edit my bios to add some voltage and raise CCC limit?

 

[BAGZZlash]

Why don't you read the tutorial and learn how to do it yourself?

 

[steve30x]

That tutorial is a big help BAGZZlash but the new Catalyst 8.8 drivers are very picky with what is done with th bios. Ive just stuck with a pre moded bios from ATI (795 / 1100 max in ccc 990 / 1250) and modified the fans to be quiet under Idling but keep the GPU cool under gaming.

 

[tomcug]

If you send me your BIOS and write what you want me to with it, then I'll modify it for you.

Question about the clock settings

There are ten clock setting groups. I think I understand that the 7,8 and 9 groups (UVD) are for 3D processing. Hence to over-clock for gaming 7,8 and 9 are the only ones to change. Am I correct?
Thanks.


One more question, does Overdriver have to be on for the card to over-clock?

 

[BAGZZlash]

Please read the tutorial, it will answer all of your questions.

 

[Muhad]

Please read the tutorial, it will answer all of your questions.

I read the tutorial. It doesn't say, in any way I can understand, exactly what I need to know.
