-you download this:
http://www.techpowerup.com/downloads/1061/mirrors.php
-put it on a bootable usb stick (to make a bootable USB stick google "hp drive key boot utility"
-then boot from the usb drive
-type: atiflash -p 0 (newbios)
if the SSIDs don't match then type atiflash -p -f 0 (newbios)
Yeah, you're probably right, but in a previous test I tried 680/1100 and ATITool started giving me errors and artifacting, so I guess a higher mem overclock is somehow limited on my card. Furthermore I've been following some user reviews throughout the web and in most of the tests the jump from 1075 to 1100Mhz isn't giving higher performance in games or higher framerates, actually in some cases the performance lowered a bit, perhaphs the mem chips are encountering some gpu bottlenecking, I don't know...Quote:

You can also use ATI winflash. 2.0.0.7 works in Vista 64.Quote:

winflash has never worked for me. Always freezes on launch and cpu usage goes to 100%.
Booting from a usb didn't work. It told me it can't boot. BUT, Winflash 2.0.0.7 worked for me - thanks!
Guru, I used your bios, and edditted it so that my ram is lower (It doesn't work well at 1100mhz) and when i flashed, my old overclocks were still the same as I had set from CCC....
Any thoughts.
That said, I forgot to back up my original bios :shakes:...sigh...
To follow that, there is a BUG in RBE 1.10 and 1.11 which misinterprets Voltage values if you are in countries where decimal separator is "," (comma).Quote:

You need to disable overdrive otherwise CCC takes over.
could not get 950 mhz core stable.. no matter the volts... added some 2.5v uf800 caps to the back as well.. still should had a few more..
also..... in the voltage settings i had to change ALL(including the "---") of the voltages manually(in RBE) so i could even break 920 mhz.... the voltages would go from 1.58v to 1.43... once i changed all the voltages in RBE it was artifact free and droop free... i gave her all the way up to 1.7v on the core and no go still at 950. but 1.54v 920 is stable..... load goes to 1.59v from the 1.54v idle...
just an update... :up::yepp::cool::D:p:
K. I saw the clocks until ati took over.
I try to disable it from the CCC, and it re-enables when I click apply.... is there a registry key I need to change?
what kind of temps are you getting with the Accelero S1 @ 1.58v 920MHz? I wonder if you are just about reaching the limit of the 4850. The 4870 is supposed to have much beefier vregs / phases, and the additional 6pin powerQuote:

@miwo
temps were hitting 55c load, 38c idle.... the s1 does a great job... :up::yepp::D
w00t this has convinced me to buy a 4850! can you guys put up some 3dmark 06 scores?
thx, Ali
so i installed rthdribl and ran it, changed the multisampling to 16x but every 30 seconds the screen starts skipping and I get 2fps, it also did this with 4x multisampling.Quote:

Glad to hear! I was scared I made the clocks a bit too aggressive but I'm glad someone besides me is getting it to work :DQuote:

Hey guru I'm having an issue with the 2D profile working with your BIOS. It seems to run with the 3D settings all the time. I did, tweak it a little, but just for the Fan profile.
Also (possibly) unrelated, this is what happens to the Overdrive tab in CCC for me, it occasionally flashes to show what should be there, only with blank values. (see attached file) I don't think that should be normal :p:
This is with the Hotfix Driver. :shrug: I've tried reinstalling it, seems to only be a CCC issue, as the in game performance is solid so I dont think it's in the drivers. I'll try stressing it with the crysis bench and see if maybe it just isn't stable?
hmm that's odd, I don't know what to say as the 2d profiles are working fine for me? Perhaps it's a bad driver install? How about downloading a stock bios from the techpowerup database and editing it yourself to see if you have the problem again.
On another note, I just did a 3dmark06 run and am pleasantly surprised at the result. This was at 720/1200 with an E6750 @ 3.64ghz, 4gb OCZ @ 1090mhz 5,5,4,14
Not bad for a dual core and single card.

it is weird actually, cause i had a 725/1050 oc which ran fine, then i ran rthdribl and it would do that 2fps thing every once in a while. Then i flashed the bios to 750/1100 and when i restarted, the mouse was really lagging, i couldn't do anything in windows.Quote:

i gave the 750/1100 oc another try and now the computer is working flawless again and rthdribl is not doing the 2fps thing anymore.
not sure what the problem was exactly.
but thanks for the help. i have 44 load w/ the accelero.
Hi!
I figured what may be part of the problem. As you know, some clock info settings of RBE are locked by default. As this was helpful for 3xx0 cards, it might be disturbing for 4xx0 cards, which is why from RBE v1.12 on, it will be turned off by default.
In RBE v1.11, it's on by default and so, it kicks in: RBE loads the BIOS and displays the clocks, but due to the lock, all locked clocks are the same. Again, for 3xx0 cards, these clocks really were the same, but not for 4xx0 cards.
Even when you unlock after loading the BIOS, the information is gone. So, I made a screenshot with lock turned off by default and RBE shows this:
http://freenet-homepage.de/BAGZZlash/Unlocked.png
So maybe you should consider changing clock info 3 to 9 for overclocking (at least 3 and 7 to 9, for I'm pretty sure 4 to 6 are used in UVD mode only), clock info 1 for 2D mode and clock info 2 for low 3D mode (i.e. Vista aero).
A 4870 BIOS I loaded had "high" clocks at 3 and 9 only (besides 4 to 6 for UVD), so maybe this may be enough for overclocking. Clock info 8 is medium performance setting (i.e. for Vista aero) for state 3 then. See:
http://freenet-homepage.de/BAGZZlash/Unlocked2.png
Furthermore, clock info 7 may be the 2D setting if the card is at powerplay state 3.
Long story short - You maybe want to use this as a basis:
http://freenet-homepage.de/BAGZZlash/Unlocked3.png
I entered a GPU clock of 710 and a memory clock of 1030 MHz to denote "overclock here". Enter the values of your choice.
I'd be glad if anyone gave me an update about whether this was useful.
I'm currently testing with Gurusan's bios and i figured out that you don't need to set vgpu at 1.4v in bios to get 1.21v (read out with DM)
This is what I got:
1.40v set in bios gives me 1.9v ( 1865 milli v to be exact) on my DM
1.30v set in bios gives me 1.9v ( 1865 milli v to be exact) on my DM
1.25v set in bios gives me 1.9v ( 1865 milli v to be exact) on my DM
Right now I'm @ 750MHz with 1.9v, not bad I think, still haven't done a hardmod :)
Will do a bench in minute

I also wonder if a 4870 can reach even more :P
Thanks bagzzlash...that makes things a bit more clear.
Am not impressed with your score unless itīs a vista score. I am not a fan boy and i will soon be picking up a HD 4870. With my old 8800GTS 320mb SC, i was able to get 15k in 3Dmark 06 check sig. Canīt you bump up the shaders clock a bit and try tighten up your mem clocks(ram) maybe 4-4-4-10.That may increase you score:yepp: Well nice score for a start, keep pushing:up:Quote:
