AMD Radeon HD 2900 XT overclocking results

[Naunaud128]

I will stick with NDA unlike some other people who attended Tunis event and already posted pretty much all the details of the card. There are also quite alot false information floating around the internet regarding Radeon HD 2900 XT.. main source is one particular site which is not so hard to guess.

Anyway, there is actually quite alot overclocking headroom in R600 GPU and AMD GPU Clock Tool seems to be working just fine. I had a problem with Powerstrip beta-version which was limited to driver's limits. Now we just need to wait for new version of ATITool which brings voltage adjustments for R600 and I'll run tests under dry ice cooling. Hopefully that'll be next week.

PS. 1000/1000 MHz clock speeds at techPowerUp!'s screenshot are pretty modest

Kombatant, nice to see you again

Gee, this card rox !

1000/1000 is pretty impressive (if it's really that easy to obtain those clocks)

btw, waiting to see your results sampsa

W1zz is still working in the ATT to work properly with R600

Am I missing something there?

[DilTech]

Think again

For 24/7 usage?

Sure LN2/D.I./Cascade cooling is fun, but 24/7 gaming ready is what matters.

agree 100%. I am expecting mid 800's for core and late 900's on memory for 24/7 with a half decent clocking card.

[theteamaqua]

yeah ... but ATI tool can prolly let u adjust voltage , and with water that means much more clock speed

[GLENBOY]

good point the teamaqua

We have a section for that

Notice the "Xtreme" in Xtreme 3D

I want serious some benches :P

@ 1000mhz core, these cards will be very capable of dealing with the competition. This is gonne be a long 10 days

[Daveb2012]

I don't predict any WOWs due to kinc and samsa.., please prove me wrong.

[ahmad]

Damn the NDAs. How much money it would it take for you to disobey

[bloodbanger]

okay,sampsa:perhaps you can answer this:Somewhere there was a quote(from Kombatant?)where he states that people are going to be pleasantly surprised?Any information on what he's talking about?Or is that part already been covered in a preview?I just wanted to know in what point of view we'd be surprised..

[Your_Boss]

Think again

Someone at overclockersUK said that those 1000/1000 speeds were with 2D clocks just showing you the options it can do.

What can your card really do on air in 3D mode? Thanks.

It cant do 1000MHz on stock cooler. That would be sick really

[flopper]

its water or cold that is eneded, 225w is kinda hot.

Yeah. For every overclocker this card will be a wet dream For me its always nice to know that there is much headroom by just removing more heat.

Those who like to build with watercooling will find the perf. gain from building with a high end watercooling system very pleasing.

But on air? How bad will it be limited?

I know I've been tossing the idea of going water again but not really 100% sure yet.

So waterchilled 24/7 setup ftw ?

[VictorWang]

the cards are ready, just need to improve its driver.
hope to see 5%~10% performance gain in the next 2weeks

now...from 4.01~4.19, already 2~3% there.

[-Acid-]

any one have any idea as to the heat output of the card in 3d mode it would be nice to know for any budding water chillers getting build atm

[Dynasty]

Here is link to an unknown card in 3D mark > 03/05/06....
Geez, I wonder what this card could be.

Dammit, time to shell out for that new Thermochill PA120.3...my BIP3 struggles to dissipate the heat from an X1900 @ 750/820.

[biohead]

having an SI-128 waiting to be bent and mounted on this thing.. guess that'll shovel most of the heat outta there, say, more or less equal to water?
