[Guide] Installing AMD Radeon Mobility 6970 / 6990 in your M17x R2 (Single GPU and CrossfireX)

[DR650SE]

I know. I'm not sure what I should sell the 6990s for. Any suggestions? I wonder if Table21 will take 2x5870M and 2x6990 as a straight trade for 7970s....lol

ROFL! If you get an answer, let me know how you go

Mine are ES so I would have to sell for less....not sure.

7970s are the reason i want to sell my 6990's lol Since a single 7970m>CF6990m. I just want them on my 17x in CF even if it has Fan's at 100% i wouldn't mind using HWinfo for them beast's.

I was offered $200 for 2x5870M shipped to god knows where but i'm going to keep these. I would take anything over $600 shipping on me for my clevo 6990's.

Yeah the stats are impressive, but I think the single 7970 was about the same as 2 x 6990m's....I wouldn't say it was more powerful.

Still, damn impressive. I read that someone picked one up for 450?

well if dual 7970s work as well (or better) then the 6990's then this laptop could last even longer. I'm still waiting to see what the M18xR2 looks like, but at this point no reason to get rid of mine.

Plus if the 7970s work and push out some good numbers it might take me even longer.

Very impressed with the R2

Hey Douse and Xeroxide. Thanks for the replies. I'll try the 12.4 previews, turn my TDP/TDC down for gaming and restore stock voltages to experiment.
Lowering brightness is such a shame and the PSU upgrade is too much hassle.
I'll also disable ULPS like I used to to overclock the 5870s

Thanks a lot guys!

Edit: Really speaking in regards to upgrading the GPUs in the R2 to 7970s I won't. I love this screen and the assembly of the laptop but I will not modify it anymore. The processor, RAM and Mobo are aging quite rapidly now. Will probably hold off until R4/R5

Douse, I just noticed your sig - how did you manage to get a 480W PSU to work with your R2? You could defo get dual 7970s then!

Hey wonderpookie,

It was in this thread that a few of us put together two 240 watt power supplies. Aarpcard was the brain child of this experiment

I think it is around page 73 thread, feel free to have a read

Guys, I have a question. With the 7970, I thought it was MXM 3.0c. Aren't our R2's MXM 3.0b?

Wouldn't this pose a problem? Because I am pretty sure the R3 is MXM 3.0c

[maxheap]

Apparently it is MXM3.1 and it is compatible with MXM3.0b (slv7's comment)

Ah cool! Thanks
