My monitor shuts off during gameplay.

Hey,

Recently I overclocked my CPU to 4.8GHz and 1.49V in the Asus UEFI Bios utility. I started playing some games but then my CPU Usage went up to 70%, my frames dropped then my monitor turned off, and my keyboard got disconnected. But my PC was still running. Another problem is that when I play BF4 GPU Usage is at 40% on both GPU's unless I go into Windowed mode in which one of my GPU's goes to 99% Usage and one is idle. Same with most other games, my CPU Usage always rises higher than my GPU's which are never over 50%.

Specs:
AMD FX-9370 @ 4.8GHz
GTX 770 (x2)(2-Way SLI)
Sabertooth 990FX R2.0 Motherboard
8GB Corsair Vengeance Memory DDR3 1866MHz (I changed it from DDR3 1300 to 1600MHz in BIOS)
2TB WD Caviar Blue HDD
Windows 8.1 Pro

What kind of temperatures are you getting while playing?

Run HWMonitor or HWiNFO64 in the background while playing a game and post a screenshot here.

With a clock speed that high and a voltage that high I assume you're overheating. Do you have an aftermarket cooler?

I use an Asetek 570LX Liquid Cooling System

I'm also getting around 40-50 degrees celsius.
 
So it's not temp related. I'd try updating your BIOS, USB Drivers.

Also if you changed your RAM speed it's possible you need to change the voltage too. What's the exact model of your RAM? There should be a sticker on it which gives the exact model number, which will allow you to find the data sheet for that RAM stick.

Also did you stress test after you did that overclock? SmallFFT, then LargeFFT, then Blend in prime95?

I tried doing prime95 but I couldn't figure out how to run it so I thought if I played for a bit I could base it off that but doesn't look like it's doing well so far.
 


You should have stress tested after overclocking in increments. I recommend you go to BIOS and reset to optimised defaults (should be in the key on the side, on my mobo it's F5 but it differs) and overclock with a proper methodology. This should help: http://www.overclock.net/t/1348623/amd-bulldozer-and-piledriver-overclocking-guide-asus-motherboard

Look up the exact RAM model too. It's possible that by changing it to 1600 MHz it's running on the wrong voltage and timings.

Alright, seems good. Thanks for the help, and do you happen to know why my CPU Usage it higher than my GPU Usage even though it's overclocked?
 


Since you're playing BF4 MP it's VERY CPU intensive - the more players, the more load on your CPU. Since you have 2 very strong GPUs unless you're playing at a res over 1080P you probably won't see over 50% usage of them. Your CPU and your resolution are technically the bottleneck to your very strong GPUs. However there's not much you can do to alleviate that - if you want more GPU usage get another monitor, or one with a higher resolution.

Thanks! :)
