Asus 7950 DC2-V2 the best 7950?

post #1 of 21
Thread Starter 
Well, I was browsing through the 7950s on Newegg, and the Asus card caught my eye. I usually blindly scroll past it because it takes up three slots, but man, PCB on this card is crazy. It's definitely a non-reference design, and it looks to be one of the best 7950s out there. I'm just wondering if anyone has had any experiences with it, seeing as nobody has done a review on one yet.

well V1 had a lot of issues with cooling as your probably aware. V2 was suppose to fix this but i beleive they locked the voltage fairly low so not the best overclocker. mine clocks pretty good but i still need to do the fix on the cooler and isnt voltage locked.

i wouldnt say it is the best card at all. i would look at something like sapphire boost cards, msi or GB as well over the asus in the 7950 series.

Wait... so it's voltage locked? I thought it wasnt? Someone tells me something different every day on these darn 7950s!

And is the issue something you can 'fix' with just a BIOS flash?

Have 2 of these V2 models, both overclock 1200/1600, voltage is not locked (bought another one less than one month ago, and other couple months ago). These also does pretty good job on VRM cooling, imo best 7950s out there. The cooler is 3-slot tho, forget CF unless you have good spacing on motherboard.
post #5 of 21
Yea I have a UD5h, there is 3 slots between the 2 GPU slots:



I do plan on putting 6 x 7950s on my board, but that won't be too soon and once I'm past 2, I'll be putting the system on a box or something.

Basically, I can fit 2 x DC2s in my case/mobo just as easily as any other GPU. The only downside is that 3xDC2s won't fit on this board while 3xDual-slot cards will, but so what, and 3x dual cards won't fit in my mid-ATX case anyways, so I'll be moving to some plastic crate once I'm on 3 cards anyways.

Thanks so much! I think I'll bite the bullet and get this as a replacement for my sapphire 7950 dual-x boost 3l piece of junk, $40 is a lot but the extra overclock will pay for itself after a few months. I'm hoping the cooler will really do a lot for it as well.

Sapphire and Gigabyte have proven that you don't need 3 slots to cool the 7950 to cool temperatures, the Sapphire cooler is the coolest and the quietest..

I have Asus HD7950 DC2T V1, and personally I would stay away from Asus DC2 cards.

V2 should have fixed cooler issue, V2 comes with identical cooler to HD7970 DC2, also V2 comes with CUSTOM PCB from Asus (8 Phase power design).

But still I would not spend my money on it.

The V1 design flaw is in the mounting screws, not coller itself as they are too long and cannot be tightened enough.

Anyway I have fixed my DC2T V1 cooling issue by installing a X shaped backplate (which usually comes on reference AMD cards).

Now my temps @ stock 900/1250MHz , stock fan are 55C max in games and benches like Heaven, 3DMark 11 etc.

@ overclocked 1050/1750MHz, fan hits 36% max, my GPU temp is under 56C in games and benches.

On HD7900 series hole spacing is 54 mm so you can use X plate from HD6900 series or 4800 series AMD cards their hole spacing is 53.2mm or 53mm for HD4800 series.

I'm using one from HD4800 or HD6900 (dunno exactly as they are identical) series and it works great. it's a tight fit but can be used (also HD6800 and HD5800 series have 53mm hole spacing).

You can also with a power drill make holes on X plate a little bigger (widen the holes towards the ends on X plate) so you make up for that hole spacing difference to make it very comfort fit.

Also make sure that you use 1.5 - 2mm thick plastic washers under the X plate holes to increase mounting pressure and to maximize cooling performance.

Also you need original screws from HD4800, HD5800, HD6800 or HD6900 series cards to be able to mount the cooler with X plate (original Asus screws would not work).

I have fixed mine and it works good.
