GX740 able to use a 6970m?

As the title suggests curious as to the ability to upgrade the 5870m to a 6970m the newer cards even seem to be a bit cooler too so i don't see heat as a issue, will it fit in the same slot and what not?

Thnx in advance.

Newer cards will not be cooler.

It's pretty much twice the TDP of the 5870, so it's gonna run a lot hotter.



The heatsink might also not be compatible.

I'd say that an OCed 5870M would be comparable to 6970M on stock clocks, when considering the temps. With proper cooling mods, GX740 might be able to handle 6970M thermal-wise. BIOS compatibility, PSU and power circuits on the MoBo may be a different story though.



5870M has TDP of 50W, but that's for the GPU chip ONLY, whereas on an MXM module there are also GDDR5 chips (which run very hot) and other components, which also generate heat. I think that an entire 5870M MXM 3.0B module has TDP of about 75W (on stock clocks).

How much would the 6970m use? The PSU can be fixed with buying a bigger one, but yer bios and mobo compatibility as well ascooling I guess is what I would be after but unless someone has done it no one would know I guess.

The stock 6970M draws between 85W and 90W.



Plus a 5870M heatsink will not fit it, without heavy modification.

Why it won't fit?

The silver part around DIE?



5870M vs. 6970M





Eurocom:

"The card is compatible with all the notebooks and embedded systems that support MXM 3.0b graphics modules and its TDP is rated at 75W."

The Eurocom Racer has the option of a 5870 or 6970 as well as an array of nvidia cards. So unless they change the cooling for each card i would say it should fit, and my current card never goes over 80 so even if it is slightly hotter im sure it should be fine.
