I have unplugged it a few times since and cleaned the drivers. It has not showed up again since. Any idea how I can make it show up again? I have tried to use ati flash and followed the tutorial exactly. It did let me into my hard drive where I put the files but now it's saying invalid dir. So what can I do?

Very very long one liner. My tip. Make a new thread for clearly your problem and exlain how you got the invalid dir error. Use some screenshots. Sometimes an image can tell more than 1000 words.

Otherwise I can't understand if you don't understand what you don't understand....even if I want to...

virgin bios


hoping someone has a fan speed fix,as this is the 2 wire fan with no access to fan control,and it runs hotter than my arse when covered in custard.

Sorry, RBE can't do magic. If it is a 2-wired fan, it is not controllable. Face it.

i think your wrong there sir......

my mrs could control it,she trys to control everything...so i am aiming her at my card

hiya bagzz
i have 3 x 5850s coming and i want to open up the ccc limits to a much higher level but i'm sure that even an asustop 5850 won't have theccc limits i'm looking for i want 1200gpu and 1400 memory limit, could i use the signature file save from asustop 5870 and then use that sig file in rbe on the 5850 bios or might it work using the method 2 way,thanks in advance and RBE is a brilliant utility

[BAGZZlash]

No, don't do that!
On the one hand, signature saving isn't working properly for 5xx0 cards anyway yet, on the other hand it has never been a good idea to interchange signatures among different video card types. Don't do it.

[glenboy]

ok i'll wait a bit till rbe is updated and maybe there will be a few 5850 bioses to choose from then as well

Not exactly true... mine has a 2-wired fan and fan control works fine.

I sent you an email a couple days ago (Oct 2nd) about 4870/4770/5770 programmable VRM
Pls check your mail !

[newfellow]

Since when has GPU fans have had 3 pins?

Anyway, just checked RBE seems, damn nice software. Tested all sort of BIOS editors in past couple days for ATI cards seems this one actually works very well and has all the features needed to tweak these cards.

Although, I am wondering does the hardware rule nr.1 apply here still "Always flash in DOS". Kinda have still something even against to MB BIOS flashing on OS.

hello BAGZZlash

I have a question for you,Could you please help me?
i have send a PN @ you

[overclocking101]

ok i flash rbe modded bios to my 4870 512mb and it shows clock speed of 80mhz! and it was set to be 800. i used the over/underclocking utility in rbe. maybe this has something to do with it??

You mean you used the clocking wizard? Could you post the modded BIOS?

ok

[Methanoid]

Is it possible to flash a modded BIOS to a Radeon HD4650 to persuade the OS that its in fact a HD4670? Presumably changing the chip to RV730XT and the Videocard ID to HD4670?

You may think this is a mad thing to do (when leaving the clocks unchanged and when 4650s have DDR2/3 and 4670s have DDR3/4/5) but there is a good reason. Apple are now using 4670 in the new iMac and hence there will be drivers for the 4670 in OSX. Unfortunately there is (and won't ever be) no low profile HD4670 so all I have is a 4650 but I'd like to run an OSX Hackintosh.

So it would be nice to persuade OSX that my 4650 is a 4670!

[BAGZZlash]

As far as I know, Mac-video-cards are kind of incompatible to those used in PCs. All I can suggest is to flash a genuine-Mac-4670-BIOS to your 4650.

did you try with the normal drivers? chances are they still support the card, otherwise try to look for something similar to a windows inf file that specifies which device ids are supported by a driver, or grab a hex editor and try to replace the 4670 device id with the 4650 device id in the driver

This will most likely not work due to the hash protected digest zone in the BIOS.

[W1zzard]

in the driver, not the bios. but dunno if it must be digitally signed on macos

Sorry, didn't read thoroughly.

any1 can help on this ?

this is how the standard bios looks like for asus

ive tested now and changed every register step by step except 0x16 ( which is obv for idle ) to 1.1875 ( recheckt after clicking ok that he has actually taken it ) and flashed the card.

however in what register the voltage changed, it didnt change on load ???




*Edit*

I read on another forum that voltage changing through bios with cards that got 1.1250 vcore for load does not work with RBE because BAGGZlash cannot figure it out?

I also tried to change it via profiles with msi afterburner. it does not change at all on 2D/3D. even not with hotkeys ?

Hi everyone, I have a strange problem with RBE, or maybe I have a lack of knowledge, well, the thing is I have two 4890 in crossfire and I can't switch the fans to the factory defaults using RBE. Before I decided to switch back I had been using modified bioses with no problems for a very long time(the only thing I changed was fan control). So my action are the following- I take the native bioses(which were taken from my cards by RBE and were not modified), then I open them by RBE, I go to the Fan Settings and I see that RBE puts incorretc values on the graph(the speed of the fan is too high for such a small temparature). What shal I do? Is there a way to go back to the factory default fan settings?
PS I tried flashing those unmodified bioses but to no vail- the noise was horrible

[kakarott007]

hi guys. could somebody tell me if there are any chances to see memory voltage tweaks for 5850/5870 in RBE sometime soon?

[mechtech]

New XFX 4770 bios directly from xfx support. Can't upload through gpuz cause its not on the card yet. SO here you go.
