4890 OC limit fixed!

[illuminatiASUS]

Impressive numbers to say the least. In every sense of the word. Keep up the great work.

[jobol]

Will this new bios work with all 4890? or a brand/model in particular?

( I have a XFX Radeon HD 4890 XT)

veeeeery nice

i hope it can fix my oc-problem:

That is exactly the problem we are talking here I think most of us have seen this behaviour with our cards. Some of the best ones can do 1070MHz-1100MHz without 3D load on air, but that is rare.

[dinos22]

You are extremely lucky. I hope you did win in lottery too

Some cards can scale up on core speed with cold, but it is very rare. Most cards did not do much over 1100MHz on LN2, so this is the issue we are talking here.

To ceemic. Better card 1.365V and worse card 1.4125V

i benched in Xfire at 1090/1175 on water but i was disappointed going to SS phase with -50C on the core as it couldnt pass nature at 1150Mhz even >> is this what you are saying you fixed? cold scaling? with bios? did you fix the volt limit they have?

so whats the point of telling us about a it if you dont want to share the info.

Yeah.. you are the one who have been hitting your head in to the wall

Cold is not the problem with these cards and you can't fully fix this problem by cooling your card. Voltage is not the problem and voltage does not fix it either.

I see you dont have the clue what is the problem, so calm down

Point of this thread, is that you can see what these cards can do under LN2 etc. This fix will be available for sure in some point. You just have to wait.

Yes I hit a clock wall after 1075 on air in vantage with every single card and I have a stack here......it can't be the cards.....and this is with a highly modded bios......so I must have missed something.. get a weird screen but its not artifacts....and it has an AMD logo when it happens.....

[dinos22]

so you didnt answer any of my questions
you can say what you fixed without reveiling how you did it i guess but yeah it's your call

calm down??? i'm calm

I will have to take a snapshot sometime.

when it first happened I was like wtf......Maybe I tinkered with bios just a tad to much....05 and 03 run higher than 1075

[crustytheclown]

Sorry but i can run both my cards 1230Mhz core with just dice and softmod, and here is proof (from low clock challenge)



The only think i had to do is fix the 2d and 3d mode to stable Mhz for both (lets say 900/1100) and the same goes for voltages.(1.31v 2d-3d).Thats why some cards refuse to go higher...they just jump from 3d to 2d mode (especialy in 3dmark03-05 and for no obvious reason).With this hint you don't have to care about that...

ps i use atitool to clock both cards that high...
i have other benches too!!!

[dinos22]

lol thats pretty good crusty
thanks for sharing

[cowie]

great crusty i will try that.
over the weekend i had my card at -20 and all it ran was 1100 from 1066 on air to say the least i was pretty pissed and flustered.
as for sf3d holding...how many times as he helped us all with mods so i'd sit tight.
hes very shareing with this kinda stuff

[Oliver]

Thanks for posting SF3D , glad to see you guys & co got it all good

Absolutely true regarding there are some few cards pushing , my friends does 1325mhz GPU trough 2k5 on a SS (180 or 250w tuned unit)

what voltage did you ran 1066 at , 1.4375? and what would accour if you raise the speed from 1066 to 1067mhz GPU ?

[..::G80::..]

Mine 4890 did 1080MHz on deff cooler and volt was 1.45V.

[Mean Machine]

That would probably be the clock testing feature in CCC.

Yes. Most of the cards hit that 1070 limit on air. After that colorful screen etc. AMD logo is new thing to me.. that is quite nice feature

Well, Brandybuck and Xogolatl can run their cards at 1200MHz too, so your cards are similar. Be happy with them, really

That issue you decribed is not the one this new bios will fix. But there is a slight chance that they are connected.

Thanks for understanding I just go out early on this one. No need to get upset people

1325MHz is very good core speed. I hope that he an submit the scores to HWbot, so we can compare.

I am very sorry if you guys find this thread annoying. Moderators can delete this, if it will get too nasty. The reason I am holding info, is quite clear. I am not the one who decide what will be public and when. I am just the messeger and usually you don't shoot them

woa, look at those high frequency of graphics

I'll bench with them first and then I'll upload some pics.....

[Vivi]

hipro im sure you can even fix people with hardmods!

crusty if yours did 1230 dice, imagine what it does with unlocked bios? or have i got the idea wrong here, what exacly limits the cards?

[SF3D]

Interesting. I really like to see how you fix this

Well.. partially wrong. Those cards which can do 1200+ already are very rare samples. Results with those cards are unpredictable

This will be very nice for most of us with normal samples. We will benefit most about this fix.

ROFL hipro thats the spirit hahaha
