Check out the ghetto cooling. Love it.

[LowRun]

Holy crappola, it's doing 1000/1000 on air

R600 can't walk on water but it sure can fly and with the 357€ that has been seen on some site already to my surprise i am even considering crossfire in a not so distant future, DAAMIT

It's better to invest in watercooling than to invest in crossfire for now...OR

If you are bent on buying two cards, wait for the XL...two of those will be more nominal with similar performance.

It will be a little more than 320mb price range but still retain the 512mb gddr3 of the XT.

[awdrifter]

How does that score stack up with the 8800GTX?

Perkam dude, i just can't pass on the 2900XT, it's gonna be cheaper than what i paid for a 1800XL, perform like a champ and OC like crazy (if retail is the same than press samples). Too sweet a deal

I aggree... Cant wait to see what 2 of these in crossfire on a x38 chipset is gonna do....

You can say that again... For what you get its an incredible price.

[DilTech]

Agreed.

[Mago_10]

what's the difference between GPU TDP and Board TDP ?


so the R600's(GDDR3) power consumption is 160 or 225 ??


and G80's Board TDP is 225W too , no ?

[DilTech]

Board is the total power for the entire board. Gpu, ram, and other various chips.

The 8800GTX is 175-177, I can't remember which, total.

[Mago_10]

so the important thing is the Board TDP not the GPU TDP ?

[KTE]

Very good news...meaning AMD users with 3ghz rigs will be able to get 12k-13k scores with an oced HD 2900

Perkam

12k is at stock with a stock QX6700.

Oc'd, plenty of room for higher with 8.37 drivers.

The 16k ss shot from VR-Z I reckon is a QX6800/QX6700 at around 4GHz.

[DilTech]

so the important thing is the Board TDP not the GPU TDP ?

GPU TDP gives a general idea about core temp, so it's still very important.

Knowing VR-Zone, I'm thinking much higher than 4 ghz on the quadcore.

[Shintai]

now tell me how to measure the power consumption of a cpu

By measureing it before the VRM. Thats also why 1 CPU looks to be out of spec.

[largon]

It's always good to read the article one quotes.

the numbers given do not take into account the efficiency of the CPU voltage regulator laid out on the mainboard.

[Shintai]

It's always good to read the article one quotes.

And your point being? Its the same thing. And I´m quite sure we can assume a somewhat equal efficient VRMs. So making all numbers alittle lower would what? Change anything, not really since the point was it had LOWER TDP!

So counting the loss in the VRM just makes it even better.

[Brother Esau]

Are we still under the impression that May 14th is the date?

[largon]

Shintai,
Sorry, my bad. I slightly missinterpreted what you said.

[LowRun]

Are we still under the impression that May 14th is the date?

Should be unless they changed that again but then they would upset a lot of people.

[nn_step]

Are we still under the impression that May 14th is the date?

yep and 5 days isn't exactly a huge wait but I'm sure many people would be upset if they delay it.

[Brother Esau]

Thanks fella's, delay would that suprise you if they did? May `14th is a far cry from the 3rd week of Febuary so at this poit it would not shock me one bit!

[fornowagain]

so the important thing is the Board TDP not the GPU TDP ?

Both really, but mainly the total TDP, this gives an idea of the power consumption from the PSU. But the core TDP could for instance be used to estimate the heat dump into a short water block attached to the core.

ATI overdrive secret uncovered

Schematics about the R600 power

The R600XT, orRadeonHD 2900 XT needs two power connectors, one 2x3 pin and one 2x4 pin. If your PSU doesn’t have the 2x4 pin one, then you can plug in a 2x3 pin one, but you wont get the full potential of the card.

You need the second 2x4 pin for overclocking, as othwise ATI's Overdrive overclocking utility won't work at its full potential. You can read more about it here>> http://www.fudzilla.com/index.php?op...=673&Itemid=34



The card will overclock even without the 2x4 pin connector, but the scores won't be great. We heard that there will be a lot of new PSU's introduced starting Monday. Here is a diagram of how it looks in the real world.

Partners to do overclocked HD 2900XT

The reference sucks

At least a few partners confirmed that they will be introducing the overclocked versions of the R600XT card. These cards will come some two weeks after original introduction and most of them will work on significantly higher clocks.

The reference card works at 745 MHz core and 1656 MHz memory. There is still no confirmation if any of these cards will use the water cooler but we would not be surprised.

With a reference cooler the card works stable at 840 MHz as we proved here >> http://www.fudzilla.com/The%20reference%20sucks

and with a better cooler such a few partners have in their labs you should be able to do even more. With water we think even above 900 MHz should be possible.

We will try to get some clocks but at this point we can confirm that the overclocked HD 2900 XT cards are on its way.

AMD HD 2900XT BLACK BOX voucher pictured


If you did not know, AMD and Valve are teaming up once again to bundle a Steam voucher in their upcoming range of HD 2900XT graphics cards. Here is some proof...






The voucher will cost AIB partners roughly $6 - 7 USD each and will be bundled with all XT cards but it is unsure at this stage if the voucher will be bundled with lower end graphics cards.

If you have Steam installed, just enter the code when the games are ready and you will be able to download and play Half-Life 2: Episode 2, Team Fortress 2 and Portal. It will be a shame if users will need to wait over a year to play the games though but the games could not be too far away as BETA versions of each are already floating around the traps.

Good times!

R600XT overclocks with two 2x3 pin
Practical example

The Radeon HD 2900 XT will overclock to 840 MHz on the air and if you havent seen that story you can see it here. The 840 MHz core on the Radeon HD 2900 XT card is possible with the reference cooler.

Even if you don't have the 2x4 pin necessary for overclocking you will be able to overclock. The plain two 2x3 pin power connectors will do the job but the Catalyst control center won't recognise that the card has the Overdrive capability.

All you really need is the GPU Overclocking tool that we mentioned and linked here and you can overclock even with two 2x3 PCIe power connectors. So you won't be needing a new PSU.
