Overclock advice

[Bean]

Hi all

I built a pc in February in has in general been fantastic and here are the specs

8GB-Kit Corsair Vengeance DDR3 1600 MHz 
ASRock Fatal1ty Z87 Killer, Sockel 1150, ATX
ASUS GTX780-DC2OC-3GD5, GeForce GTX 780
Cooler Master Hyper 212 EVO
Intel Core i5-4670K Box, LGA1150
Windows 8


I had and still plan to get a 1440p but not just yet
Mostly I was playing Bf4 and csgo and other random games at 1080 maxing out at good fps no problem

A while ago I looked into overclocking first using the EZ overclock using the API to start and then and the uefi but ran into problems. I then using multiple guides tried to set my own overclock and using intel burn test and prime and boot testing was able to pass with a 4.5GHZ with temps maxing at 90 degrees during test but under "normal high load" eg video render never breaking 80.

The problem I was getting that intermittently I am getting windows blue screen and it is forcing a restart. I ran HWMmonitor with logs and after the restart confirmed that temps were fine 

This is the error I was (am) getting (once it was different but missed that is said)
SYSTEM_SERVICE_EXCPTION (nvlddmkm.sys)

So I tried lowering my settings in steps eventually to 4.0GHZ with little improvement but still getting a crash when gaming anywhere from 5 minutes in to 2 hours in at that point I gave up as the turbo is to 3.8 anyway and am issue free but disappointed.

Yesterday I started to play arma 3 again and feel an overclock would be nice improvement to the poor fps and drops I am getting so I am looking for help in how to approach and trouble shoot a fresh look at an overclock or have I just been unlucky with my mobo, cpu combo and have to put up with what I have 

Thx Bean

really OC'ing your cpu wont make any real difference, atleast not when already using a good cpu, OC your GPU instead

[Soplias]

Yeah I would Overclock the GPU instead, even a little bit can make a noticeable difference.

Start over again, using this, from your one and only Linus:

Yea will have another stab at it it is just frustrating to troubleshoot such an intermittent problem as for overclocking to gpu it will give it a go but think I have a bottleneck elsewhere as gpu usage only goes to 70% with arma3.

Also, another huge thing that will help us help you, when you bluescreen, look at the bottom of the screen for an 0x0000000124 code for example. Also, download "Bluescreenview" and take a screenshot please, will help alot.

Perfect. Please use CPU-Z and tell me your baseclock, and if it is 100, then start increasing voltage in your bios. Also, use cpu-z to compare the voltage set in your bios to the one used when stress testing with ibt or aida64

[Morfy]

That 0x0000000124 means that your vcore is too low, for a detailed explanation.

Awesome Morfy thx for your help unfortunately I have to go out for the day now so can't do much just now, hopefully get a chance tomorrow and report back

thx
