The New GPU 'Merry Christmas' Thread

Shame about them not unlocking, still it would've only been the icing on the cake as you got a bang for buck powerhouse at a price not seen since launch day.

Just stay away from Sleeping Dogs bench until you upgrade that PSU...

I like to think he just reconsidered his stance on a 7990 pwning 290s.

did they, he only had 1 7990 not two didnt he??? I thought matt said he couldn't disable one of his cards to deal with the flickering glitch because of his 7990?? It's not crossfire on 1 PCIe slot though is it even though dual GPU card? educate me

Mmmmmm

Only dual GPU card I've had is a 4870x2, but my understanding is that as it's 2 GPUs on one card it is crossfire. I believe this is the reason you can only crossfire 2 cards (4 GPU total) where as with the 290s you could crossfire 4 cards.

But a lot of this is guesswork and assumptions on my part.

A 7990 is basically 2 7970's crammed onto one PCB, so it is Crossfire but without the need to use 2 X PCI-E slots

Correct.

Also a former 4870X2 user here. :cool:

How much strain are you putting on that 750w psu running 2x 290x?

Jokester · 24 Dec 2013 at 12:43

I would imagine it's about 600W full load.

Gregster · 24 Dec 2013 at 12:44

I ran 2 x 680 Lightnings on a 750W and they were fine till giving them some high clocks and that would kill the computer to a shut off.

He should be ok for normal clocks but not sure on headroom.

shankly1985 · 24 Dec 2013 at 12:45

Very nice clean looking rig matt. Looks like you have the Case I want to buy next 600T? Wish I had saved up little more at the time and bought it.

I wouldn't be taking the risk with that psu like considering how much the components in that rig cost

Head room may be tight, only managed to find 290x gpgpu only power draw figures, on toms it shows worst case scenario each card pulling 295w. So load dependant it could be around 600w just on the cards, 2700k is stock 95w, throw a 50% oc on that and things are getting pretty tight on a 750w unit.

Saying that, I doubt matt will need to overclock either gpu, a silly amount of horsepower at stock, even for 1440

GoogalyMoogaly · 24 Dec 2013 at 12:52

With the stock cooler I don't imagine there's much overclocking headroom, unless you've had a falling out with your eardrums and want to teach them a lesson!

EDIT:
Besides which, with Matt's BIOS editing skills he'll have them tuned and running faster and cooler on less volts in no time!

LtMatt · 24 Dec 2013 at 12:56

I will be tweaking for sure, right now im a deer in the headlights. My first time using this new power tune. Going to take me some time to figure out my ideal settings.

Yeah, to be honest I'm not a fan.

Why? It's fine at stock. And a small OC.

I'd love it if Gibbo and 5ub sent me some new toys ...

DazQ87 · 24 Dec 2013 at 13:11

Nice

the one I ordered yesterday should be here within the next hour, question is how do I unlock it?

alex_123_fra · 24 Dec 2013 at 13:28

Congrats Matt. Santa has been very nice. Look forward to seeing some benchies later.

DPD are being extra slow with my Classi. Not here till 4.30-5.30. Half expecting a call to say "we won't get round to you, too busy".

LtMatt · 24 Dec 2013 at 13:29

The first bench is in. No idea if this is a good score or not. No tweaking and no massive cpu overclocks or anything.
