Definitely you can. You'll want trifire for 4k gaming.

BTW, did someone said hot?!...

If this happen out of nowhere, re-seating the block most likely will not fixed the problem. You should check your loop. Water flow checked out?

If not enough contact, either problem with TIM or thermal tape, it should happen from day one. It doesn't suddenly happen out of nowhere.

I see. I just rely on your previous post which make it seems the issue started after installing 14.7 driver.

Did you use thermal pad on the memory? If you do, this could explains why you got high temp.

As far as I know, with Aqua block, you only need to use TIM on the memory. The pad only for VRMs.

No manual come with the block? Follow this video.

Definitely but he use thermal pad on the memory which is not correct. He should follow the manual & use only TIM on the memory.

At least it's not catastrophic mistake.

Should be enough for 5750. What is your computer spec?

45C in non A/C room? I don't buy it but what do you care right. Kudos for getting better temps nonetheless.

The PSU requirement is just a guideline. The requirement is set that way to cover the whole PC, not just the card & they intentionally set a little bit higher to cover most setup if not all.

What was the issue you having with Corsair 750W?

Set custom fan profile using MSI AB.

Why you don't want to set custom fan profile instead?

You need to set higher than that. Mine running in 80s with custom fan profile & I can get it down to 70s if I'm running the fan at 100% speed (actually depends on the ambient, if ambient maintained at 29 - 31C like when it's raining, I can run at 80% fan speed to maintain 70s Celsius). Ask yourself this, why would you want to turn down the card performance just because you want it to run cooler if you can achieve the same thing with custom fan profile & not loosing performance?

Rather than lower the card performance, better exchange to 280 or 270.

*custom fan profile means, set the fan to running at certain speed at certain temperature, increase the fan speed when temperature increase (you can use range, e.g. 60% speed for 50 - 60 Celsius).

It should be fine. This why you use custom fan profile, it only ramp up when temp increase.

I think memory is overheating. Screen go blank or black screen usually related to memory overheating or if you're overclocking, unstable memory overclock. You probably need to re-seat the cooler.

My Elpida card can do 1600 on memory no problem. With 290's, it's more silicone lottery.

That is good decision. Good luck!

My Elpida card can keep up with my Hynix card. Both can do 1200/1600 no problem.

All 290's run hot. You either use custom fan profile or use aftermarket cooler. Mine when still using referenced cooler have no problem playing games at stock clock. Either with stock fan profile (temp max at 94C) or custom fan profile (temp max at 70s to 80s Celsius), not once I experiencing any problem. Too bad you got dud card. Dud card is dud card, whether it have Elpida or Hynix memory. When overclocking with 290's, you definitely need better cooling system. You can't compare 290 with previous gen ATI/AMD GPU. There are two cheapest ways I can think of to cool overclocked 290's; 1) referenced cooler/aftermarket cooler + aircond, 2) watercool + aircond. When overclocked, one thing you need to take care is VRMs, specifically VRM1. Overheating VRM1 can affect stability. If you can keep VRM1 below 80C (seems like sweet spot for max temp), then you can easily get the card to run stable when overclocked. Did you monitor VRM1 temp after changing the cooler? Even with watercooling most of the time I play games at stock clock (stock Tri-X OC clock 1000/1300). Only when aircond ON, I'll run my 290's overclocked.
