** ATi X1k/HD 3k series overclocking guide - ATi Tray Tools and ATi Tool + FAQ **

FAO: Concorde

With the latest ATT, does the autooverclocking work? I have one profile for 2d and another for 3d and have assigned these under the auto-overclocking options

Yep, im using it

As for X1950 people, the Pros don't have voltage control atm and the X1950XTX is STILL not supported because the guy can't be bothered/can't find the voltage chip/whatever.

ATi Tool does, ATi Tray Tools doesn't that well IIRC, no voltage control...

 

[FreeStream]

Ok cool, a issue i found with ATT is you cant push the memory more than 900 .

Tools + Options --> General Options --> Advanced --> Overclocking limits

I'm just curious if there is still limited crossfire support on the OMEGA driver set. I'm pretty fed up of CCC and I'd like to have crossfire running in OMEGA. Any recommendations?

Fraid not still stuck with ATi + CCC because of crossfire support :/

Is it the 90nm or 80nm core?

I think its the 90nm but here are the core/mem/mem buffer voltages for each.

90nm: 1.475-1.5/2.16/within 2% of mem V - depending on temps, try and keep it under 70C.

80nm: 1.425-1.45/2.16/within 2% of mem V - depending on temps, again try and keep it under 70C.

Im running a sapphire X1800XT with arctic cooler X2

Catalyst 7.1 drivers
ATI Tool 0.26

I am currently running 700core 800memory with default voltages

voltages show the following in ATI tool-

Vgpu 1.375
Mvddc 2.097
Mvddq 2.097

I idle at around 54/55 and load goes to around 71 highest in gaming. Should I try raising the Vgpu a bit to get more on my core clock?

71 is getting on the hot side tbh, can you get it lower? Fan speed @ max?

1.4-1.425V is fine tho...

X1950Pros apparently don't have any voltage control, they stay at 3D voltages all the time

the latest I had heard that they found some form of voltage control but cannot find any way of controlling it

Can anyone offer any help please? I'm on the latest ATi tray tools and Omega drivers and I have followed the instructions as per Concordes post but my card won't clock past 660/760 on stock volts or higher? I don't have a stock cooler so I can't see it being temps, although it could be?

Any help or advice would be great spec in sig

What are the temps? If its > 75C then Im not surprised, the XTs don't usually clock very well as it is and all the cards i have fall over at > 80-85C.

My Sappy X1900XT does about 660/790 and no more at around 75C and 675/790 at sub 70C...

Depends if you want every mhz or silence really

Hi mate

Ok found temps showing 40 and I have just been playing COD2 for 30mins?

And I have a aftermarket cooler even if I put the fan on 100% it doesn't sound any louder?

current clock 648/756

Ok thats good, yea you can up the voltages!

1.375-1.45/1.475V is find if you can keep it under 60C

Mem, 2.1V-2.15V is fine, although the mem controller will fall over (easy to spot - screen covered in artifacts, even on the desktop

James will you be doing a HD2x00XT series guide ?

If someone sends me one LOL

 

[FreeStream]

When did this fall off the sticky list? Is there any chance of getting an updated version to cover the 3850/70 as well (not that the mechanics of OCing them are any different, but maybe some stats on what to expect) - I know when I clocked my x1900 I found your figures hugely useful.

Well I suppose I could.

I still don't own one of the cards tho.

Would be nice if someone could send me a HD 3870?

Ill do it when I get back tonight will images and stuff.

 

[FreeStream]

Ok its updated in the sense I've done it how I should have done it in the first place.

Any ideas for the FAQ?

Also got to get my head around R600.

Can someone give me a card list with stock clocks and voltages? That'd be grand.

Cheers CR.

 

[FreeStream]

Thats 99% core issues.

up the V or down the clocks or up the fan speeeeed

 

[FreeStream]

Hmmmmmmmm!

Can you test at 2D clocks?

Card might be slowly dying so you might have to work up from there again.

Cleaned the card recently? Place a fan over the entire card? FYI my temps are Core: 60C Env: 40ish C and Regs: 50Cish

 

[FreeStream]

Its buggered then.

I assume thats without ATT running and without any of the services running so its 100% running stock clock stock V?

If thats true then its shagged. RMA time.
