Are you gonna overclock?

Rebu · Jan 29, 2015

Yonose :

Yes, I expect it. Only enjoy myself.

Okey then you want to change your PSU

Look at this link where it show you what is a good and a bad PSU:
http://www.tomshardware.co.uk/forum/id-1804779/power-supply-unit-tier-list.html

Everything under tier 2 and below i wouldnt use for Overclocking, your PSU is at Tier 3.
So i would rather go for a PSU at:
- Tier One
- Tier Two Clas A

I would recommend a XFX Pro series.

CS series (High inrush current and +12V ripple levels, only on high levels of load)

Get a different PSU. You have a high end build and should be using a tier 2B or higher unit. The capacity is ok, the quality is not.

PSU Tier list: http://www.tomshardware.com/forum/id-1804779/power-supply-unit-tier-list.html

I'd recommend a 650w or higher unit by EVGA (B2, G2, P2 or V series. Not B1 or W1 series), Seasonic, Antec (True power classic, High current gamer, Neo ECO (models with same internals as Seasonic S12II)), Rosewill Capstone series or XFX TS series.

You might also consider a different motherboard and CPU cooler. That's a micro-ATX motherboard and might not have the best thermal qualities for an 8 core chip. The same board, but it's big brother, the Z97X-Gaming 5 would be fine or the ASUS Z97-A would also be a good choice.

The CPU cooler isn't really a performance model, so if you only plan to run at stock speeds it's ok, but if you have any plans to overclock or add a second GPU later, which is going to contribute significant heat to the internal case temps, I'd get something with better performance like the Noctua NH-U14S.

Darkbreeze strikes again!

Heh. Where? I wanna see!

Joseph DeGarmo · Jan 29, 2015

LOL!!

Rebu · Jan 29, 2015

Ok, I'll probably go for another PSU. What's about RM 650?

Darkbreeze · Jan 29, 2015

I would avoid Corsair power supplies altogether, but if you insist on a Corsair PSU, the AX and HX models are the only good ones. All other models currently listed are Tier 3 or lower. RM series is no better than the CS and CX series units.

Take a look at the PSU Tier list I linked to above and find something that's 650w or more and listed at a position of Tier 2B, Tier 2A or Tier 1.

Rebu · Jan 29, 2015

I find the RM 650 in Tier Two A.

Darkbreeze · Jan 29, 2015

You're right. My bad. I don't know why I was thinking it was a Tier 3 unit. That unit should be fine.

Damn! The GTX 970 has 3.5Gb, it's the biggest problem in the universe. The last month it was the best performance/price graphic card ever built by Nvidia and now it isn't true... Jajajaja. It's true that Nvidia lies us but, the performance of this GPU in this price is incredible. Should I return it? Mmmm... I'm going to have a month to probe it (Amazon garranty) so I'll check it and then i will decide.

What do u think about it?

Joseph DeGarmo · Jan 31, 2015

The GTX 970 can go up to 4 GB of memory, but the last 500 MB of it is set as like a boost VRAM. It will easily reach 3.5 GB, but it will take a lot to push it to the full 4 GB. The highest I have seen mine go is almost 3.7 GB when running DA: Inquisition maxed with 4K DSR. I had the game capped at 30 fps, though, so I'll have to remove the fps cap to see if I could break that record.

Rebu · Jan 31, 2015

Joseph DeGarmo :

I have a question about it. Is it a hardware or a software problem?

Joseph DeGarmo · Jan 31, 2015

It's quite common for the GTX 970 to do that. But now I just confirmed that my GTX 970 has just broken the 3.9 GB barrier. I ran Dragon Age: Inquisition with all settings maxed, 4xMSAA, 3840x2160 resolution using DSR, and the 30 fps cap removed. The game was still running at about 15 fps, though, but when I triggered a cutscene, the video memory usage went through the roof and I recorded 3.95 GB of VRAM usage. So yes, I have confirmed that the GTX 970 does indeed carry the full 4 GB or VRAM, not 3.5 GB.
