Photos of AMD’s highly anticipated Radeon HD 6990 Antilles GPU recently hit the news circuit and created lot of stir. Now the company has come through officially with details, only some mind you, and specifications of the card, and these are definitely impressive.

As has been known for several months now, the Radeon HD 6990 is a dual-GPU graphics card and is planned to be the successor to the Radeon HD 5970. The card will boast of two Antilles graphics processing units (GPUs), each manufactured on a 40nm base. The twin-GPU configuration will increase the number of cores to a massive 3,072 stream processors.

To swing such numbers, AMD will be weighing the card with lot of memory - 4 GB, all of it GDDR5. The memory modules are connected to the GPUs through two interfaces, each of 256-bit. AMD also revealed that the HD 6990 will have two PCI Express power connectors - an 8-pin one and a 6-pin one. For dual-card configurations, the HD 6990 has been equipped with a CrossFireX connector as well.

For display connectivity, the Radeon HD 6990 card will come with four mini DisplayPort outputs and a DVI port. To top it all, AMD has designed a single fan cooling solution with a backplate for extra heat dissipation, with the fan sitting in the centre of the board.

The only part missing from the details are the clock speeds, the pricing, and also the expected date of release. But with so many specifications available, it is only a matter of time before the final details arrive... not to mention the card itself.

Tom thank you for your time and speed at which you reply. B)
So I can easily install the Noctua without touching my RAM which has cooling fins black, smaller. After carefully watching the video, I think strips Mushkin are not higher.
I have another question: I'm in no hurry to make my purchase. Noctua will not have a new cooler provided in the near future ?

You need to remove the fins. If you mean the old dominators where the fins are not removable then it will not fit.

Thank you for your reply Tom. :) Here's the model I use:Dominator
No news on possible new has come into the cooling world? ;)

I was looking at getting a Noctua NH-D14 but saw the issues people are having with the height of their RAM. If you go to the Noctua website they actually have a compatibility list:

You’ll notice that the Dominator RAM will work if you remove the top heatspreader (as Tom said above) held in place by the three screws:

Hope that helps

Thank you for that. I trust Tom, who regularly influences my choices, so no problem. ;) Thank you all both. :)

I have the same setup, what I did was this.

Hi all, Im aobut to buy an Asus P6X58D Premium, Noctua NH-D14 and Crossair Dominator GT. Will they fir the same way as in the foto from Beto???

Or I really need to remove the heatshink or one of them??

Will that void the warranty?

Thanks all.

it depends on the motherboard as spacings are different between the CPU and ram, you may have to remove one of the tops but it doesnt void waranty

Thanks trazomfr for starting this thread I was in need of exactly the same information.
I've got a corsair H70 but the CPU temps are too high to get above 3.8 OC so was glad to read that I can fit the noctua with a small mod.

Thank you for photography Beto, I initially thought you had done. ;) Tom gives the solution for mounting as "normal"and is also advocated by Noctua as Hoss said. Assembly is relevant to the offset of the fan is lower than I expected. I have the same RAM as you and the same motherboard is ideal. B)
I am a novice in the world of PC hardware. I just find it strange that there could be compatibility issue between something as powerful. Because if manufacturers tried their materials with elements not to their level. Or the cooling systems of RAM are useless, and few people use them. :blink: You probably know better than me. :rolleyes:
