nice :up:

let's see this mod and how 1400 mhz performs, I'm really curius and interested :)

EXPANDER, will show the hard mode ;)? or you will show 3256436256 screens with high mhz and no benchmarks :D

I can push my gpu in 2d that high too. Come on, show us some scores with that frequency:yepp:

bin size it's the same , the card is the blue sapphire reference, same pcb or the red but i cannot flash the bios said SSID mismatched.... what the hell ?? how can i do this flash ?

EDIT: problem solved with -f command :D

Correct me if I'm wrong but shouldn't pixel/texture fillrate be higher with those kind of clocks?

You can check what pixel fillrate and texture fillrate are at 1250MHz : http://www.xtremesystems.org/forums/...&postcount=225
(for lazy ones: 20GP/s and 50GT/s)

Expander.. this is not the first time you post some paint screens. Why do you need to put those white bars in there. Something under NDA :D

Please, don't do it anymore. Show us some full benchmarks and pictures of modifications. I am getting really tired of your play here :shakes:

Anyone here with some real results?

i am trying to play on ln2 and the card play very well with the original bios(connect 3d) ,then i am trying with yours bios and i take the same score.that bios(mod fix) dont work with all cards very well!

Yes, that is typical situation. If your card can do 1200MHz+ with original bios, you will not need this fixed one. It will not help you at all.

Funny, that this thread is mostly populated by people with "good" cards. All the guys who got gain from this fix are not posting anything. Well, that is the way it goes :D

now the ln2 distributors are closed here, so i can't test my cards:mad:

but when it open i'll have a quad cf ln2 cooled benchmarking session:up:

Well, i'm not a hard overclocker but even then i'd love to see how far my watercooled Sapphire goes but the thing is... i don't really know how to extend the 1000MHz limit in CCC for overclocking, pardon me the noobness :rolleyes::D

If someone could clarify that for me, i'd try it.

Does anyone know if its possible to increase voltage on the sapphire 4890 vapor-x through software? Ive read that it might not be possible.. Im getting my card soon so i hope its possible.

If its not, is it possible to reflash bios and set higher voltage that way?

I think to use software to adjust over 1.4+ u need to move 2 resistors:

http://a.imagehost.org/0234/85.jpg

The 2 pins should be 1,1 , I think they are 0, 0 now, i think the 2 corresponding pull-low resistors moved down becomes pull-high then prolly more volts can be used by software.

@ LardArse
correctly identified, required try.

[ Ovp ] mode is required.

My cards are in QC ;) will test when they get back, then test with yours and after with yours and my bios combined.
