Oh no George hasn't started messing with these cards.And besides if it was hipro's you would see 4 trimmers and definately a couple of capacitors there

[crustytheclown]

Here you go gentlemans!

Enjoy and push the limits!

[road-runner]

Will it work on HIS cards?

[SF3D]

It should work on all reference 4890 cards. If the PCB is different or the bios file size, do not flash it.


Reminder:
Everyone have to remember, that by flashing this bios you will loose warranty on your card. If you damage or break hardware by trying this, it is only your own fault. So, if you are not 100%, that you know what you are doing, don't do it.

Suggestion: Use latest atiflash.

[dinos22]

if ppl brick it it may be possible to reflash back to original bios

i suggest you guys read eva's thread if you are noobs in flashing VGA bioses like me hehe

saved my 4870X2 while experimenting with bios mods last week ahahah

oh i also have a handy PCI Matrox VGA card for reflashing card back to original

I re-shared the file. A packaged file is saver.

Works fine on all my HIS cards, Thanks...

Is the 2 fan ASUS TOP model still considered reference? It's the black and red version, with 2 fans, and a 6 pin + 8 pin power connection.

So.. is this confirmed to do anything for HD4890 under LN2? I'm going to put a single HD4890 under LN2 and curious if this will gain me anything.

[road-runner]

Only thing I see it done is increased the core clock in CCC to a maximum of 1500, still have to give it some voltage or I do on air...

Well, try your card on LN2. Then flash the fix bios and see if something will get better.

I got a huge gain in clockspeeds:



Again:

This bios will not make any card overclock better. It will remove some limitations from bios, so the card can go to it's limit without problems.

Voltage + PWM design is the next issue. Hipro etc. can bypass this and then these cards will fly.

I have done my part now.
