700mhz wall on HD4850 is smashed.

w1zzard says that CCC is locked from the driver side, not a setting in the BIOS if you read the comments on the Diamond 4870 Black Edition news article @ TPU. You never know though, maybe it is the bios

highest core i got to was 920mhz on 1.48v 100% artifact free. So was 910 on 1.45v. Currently back to jsut a basically stock bios flash though (1.2v 750/1100).

Can you send me your bios, that you use to get 750mhz stable, thanks.

Here it is. You might want to play with the fan settings as I haven't touched those in awhile since I'm now on watercooling

can someone of those with 900mhz and a 4ghz quad do a 3dmark06?

thats about the power of my next rig :P

The limit of overdrive's maximum overclock is actually saved in the BIOS. However, the section in it is protected. You can change the value, but the check notices and completely deactivates overdrive, then. Now a vendor with access to the BIOS' source code can of course set this value to anything they like. Selling that as a stunning feature is immoral, to say the least. I hope they get in trouble with ATI for that.

Any help is welcome, if u are going to answer something else that is no good or helful for me, the dont answer at all.

Thanks.

How to use atiflash360....

Do I use it in dos or what? need big help with this

[WiZARD_hun]

this is how my card looks now:

+there is a 80 fan blowing to the card.

the problem is, that the power circuit is still 80+ °C under heavy load (fur opengl).
I think it is too hot
how are you cooling it?

[tvdang7]

just wondering. whats the MAX voltage the bios will allow you to change it to. 1.21? i know you can put what ever number but im sure theres some kind of cut off where it doesnt do anything anymore.

right around there, don't count on getting voltage from a bios. you need a mod to go higher.

[Boogerlad]

what is the least amount of voltage that bios can give you for 2d? just wondering cause if i do the hard vmod, then that increases both 2d and 3d clocks, and while i'm in 2d, that just wastes power. so if i lower 2d voltage to maximum minimum and raise 3d to max, and then do the hardmod, i get better performance in 3d, but less wasted power in 2d.

That is my conclusion as well, but I haven't tested yet.

.94v is the lowest that works via the bios

[WiZARD_hun]

pls help. I can't modify any bios. When I save it with RBE, and the load, to check it, there are only "---" at every voltage.
what can be the problem?

[albon]

RBE bug. Go in Control Pannel -> Regional Options and switch standards to English(UK).

[Boogerlad]

Thanks!

If I recall someone posted a picture of a HD48xx card with extra caps on the back, but i can't seem to find it. Does someone have a link for me please? Thanx!

[JamesBong420]

i have added only 2 caps to the back (2.5v uf825).. i shall finish doing caps sometime soon.. freaking moving and then going to lake powell on the 7th.. so i am SOOOOOO busy..... i will for sure post pictures of the mods when i am done..

[gurusan]

What sort of caps? I have a bag of Sanyo WG 16v 1500uF caps that I used on my creative...XFI

[Miwo]

I took a bunch of pictures of the caps and will try to list all of the ratings if I have time when I get home from work

[JamesBong420]

the exact ones i used..

thx, it works.

can I set any voltage between 0,94-1,263V? or is there any minimal step?

Nice, the United Chemicon PSAs are supposed to be one of the best caps to use for replacement/modding on power sections due to Low ESR. Panasonic FMs are also widely available and cheap to boot that should be great replacements. I may try to add a few in the back.

I think the largest cap on the 4850 was a 16v 1000uF but I have to doublecheck. The black one or the green one, i dont remember

bah if I order from digikey i probably wont get them until after the holiday

If...If I want to use it on my Asus card, is that allright to use ur bios settings?
Can I download it and flash my card with it?
