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.

So this was done without new bios. Cool! Your card will not need this bios, but you can try it. I am interested to hear how it goes.

Plese, stop posting these 1050MHz screens. Those individual scores have nothing to do with this stuff here. I think every 4890 will do 1050MHz :shrug:

@ SF3D

I'm new experiment is testing with 1100/1250 mhz stock cooler, air at this speed test is greater attempt to make the top-level cooling single stage or ln2. 1100 + mhz gpu.
publish information for.;)

all

protection of the OVP have cards to the voltage on the 1.45 departure vgpu is entering the protection circuit to disable this mode, hard mode OVP conditions.

My Asus Tops can only do 1015/1200 in 3DMark06. Any Higher Core MHz then the Firefly Benchmark will freeze in various places.

This is with VCore of up to 1.4375v.

Maybe I should try backing off the Memory to 1150 and then see if I can get past 1015 on the Core???

ati limited maximum vgpu voltage 1.45 / I need more for the hard-mode!

nice bios:up: But I can not edit voltset In this bios:confused: whit rbe tool.
I got a MSI 4890 OC mode bios whit 1.4375v there run 1065 on air.
would be nice,to set high voltset to,In this bios from SF3D

I believe it is. I should try it so I can see if Auto Tune can detect the cards Max Core MHz above 1000. If it can??

This is Xtremesystems :) Warnings are ment to be ignored. I clearly said, that dont flash this, if your PCB or bios file size is different from reference.

Well, your card should be ok with blind flash. Those cards might already have he change in bios, so this might not be needed anyway. This is for the reference stock cards.

With single card you can have some gain on air as well. Most of the cards will not go too high in triple or quad CF, so in those cases this will not propably help. If you use LN2 and 3/4 way CF, it is different situation and I suggest to try this bios.

In my case, all reference (separately tested) cards failed at 1070MHz on air, but with this bios those cards could go up to 1070MHz- 1100MHz on air depending how good the cores were.

So testing this bios is the only way to see, if there is any help.

I put in the other Asus Top and was able to flash the bricked one back to life with its Original Top Bios.

But thanx for giving me an Opportunity to try to use CCC to get above 1000.

Been using RivaTuner where my issues at benching begin at 1018 Core with 1.40+ v

thanks, now i tested 1075/1250 in air in 3Dmak 03 with PII 550Be stock:

yeah as long as ppl BACKUP the old bios first it should be fine....just read the thread i linked to

that way if you brick it you should be able to get it back to life still fellas

lower right 1130 mhz?

It is said that is done 1200+ MHZ

I most maximum 1100 / 1250 mhz I took the test.
prune lower

Nice gain in clockspeed. Try some more.

This is the way it should help you :up:
