4890 OC limit fixed!

[Vivi]

i see, the bios removes the limit to clock, but the rare samples arent limited.

Cool

[Viss]

Looking forward to results and mods Hipro

[ceemic]

hipro5, what kind on reference voltages are we talking about?

WHICH of "all" ?.....

[..::G80::..]

I wanna see 4890 @ 1500MHz Hipro5!

I wanna see 4890 @ 1500MHz Hipro5!

+1

That will be like a CF of 4870's on one chip!!!

[massman]

only 1.5GHz?

[EXPANDER]

4890 max gpu clock: LN2 1600 mhz+ 1.7 vgpu hard mod.

[SNiiPE_DoGG]

hd 4890 max gpu clock 1600 mhz+ 1.7 vgpu hard mod.

got a link or pics of the hardmod points? I prefer a nice hardmod to a software mod anyday....

I think hipro will go much higher with his VGA maximizer

[Oliver]

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

Yes , its quite an awesome card , will tell him to jump in an show

[T.Rex]

hi,i like to show your my first 4890 from club 3d with single stage
something like -26 load



max at that temp was 1330/1200 with 1.7v

[SF3D]

Cool card T.Rex, but fps should be 225 at least with that core speed?



I tested 7 cards today and it is 100% confirmed, that this bug is fixed.



All cards hit the (black screen) limit at 1070MHz on my room, which is almost +30c at the moment. After bios flash all cards were able to go over 1100MHz without load and around 1050MHz-1100MHz in 3D load

ETA --> One week

[massman]

Maybe bottlenecked by the low HT link?

[SNiiPE_DoGG]

ETA --> One week

thanks so much SF3D, cant wait to try the bios out on some air conditioning + watercooling

Excellent. Glad to hear that. Wonder what my cards will do with my "special" air coolers? I'll be looking for that bios.

yes its right,but maybe massman have right about the low ht,but
tomorrow i got a new asus re AGAIN and then i see what happens
because im bad with that amd

[macci]

HT at 1.6G is plenty for a single card and 3DM05 GT3. Could be something else though in the OS / Driver settings.
Run the Multi-texturing fillrate test to see where your engine clock really is.

yes i try that on the asus re,i just sold that amd coz i got
crazy at this setup soon comming i7

[TiTON]

Argh.. 1 Week ETA?!?!? I barely have any LN2 left.. hopefully it will last so I can do Quad Ln2

how did you apply 1.7v
have you actually tested volts via DMM man???????

[Martin.v.r]

nice T.REX

[SF3D]

I think Expander is predicting where Hipro will get his card He is not so good at english, so we have to decode a bit.

E: Ohh.. you were asking this from t.rex. Good question! 1.7V and the card is working..

nice T.REX

Say this again, when we have seen the real clockspeed from him. That run seems to be 1000MHz for real

[Brandybuck]

Come on petri , ı want to run 1.4ghz

[T.Rex]

i use gputool to set voltage and gpu speed and catalyst
to set mem speed because i got some issue if i set both
gpu and mem speed in gputool,but i also try 1.8v
no damage but i gain no gpu speet at this voltage

at my screen i just want to see how far i got before
my 4890 go down,so about the performance at this time
i dont care,but it will come soon SF3D
