First real OC

[tlmills82]

I built my new rig and am currently working on OCing the 4690k.  I set the multiplier to 44 as I've heard 4.4GHz should be achievable on air cooling without too much issue.

 

I ran 10 passes of Intelburntest at High settings and it passed the test.

 

Should I continue with an 8 hour stress test with these temps or should I dial it back and hope for better temps?

 

 

Also I set the cpu core voltage to 1.25 and it's showing at 1.26 in CPU-Z is that normal?

Do you have an aftermarket cooler?

 

EDIT* Just checked your profile, yes you do.  212 EVO.

Yeah 212 Evo

+\- 0.020V is normal for these chips to fluctuate @ idle or under load

 

you could try one of two things since temps look good

 

1-increase multiplier. you may end up getting 4.6-4.8 at that voltage

 

2-decrease voltage

 

i always suggest 8 hours or more for stress testing. give asus realbench a shot. its a great stresser and very realistic

 

always run your stress test using manual voltage mode aka static\override

[Faceman]

Yeah 212 Evo

Great product, used to own one myself.

 

Your temperatures are normal, and your OC is good, but we can make it better.  You can try one of two things to either increase the multiplier while remaining at the same voltage, or reduce the voltage, remaining at the same multiplier to give you better temperatures.

Which stress test program should I be using. I've heard a few options now and I have no clue lol

Whatever you do, before stress testing, no matter what program, set your voltage to manual/constant/override/static or whatever your motherboard manufacturer calls it.  When you are done stress testing, revert back to adaptive.

Ok, update on the status.  Last night before I was about to start my 8 hour stress test, I got a windows has encountered an error message and my PC rebooted.  I don't know if this was caused by the CPU set at that frequency or just coincidence.

[ProKoN]

hard to say based of your description

 

if its a bsod we need to know what code it threw, what was the error message or did you bluescreen?

 

typically x101 and x124 are cpu related

It actually wasn't a bluescreen.  It was a windows error shutdown.  Didn't give any specifics on why just said "Windows has encountered an error and must shut down"  or something similar to that.

Propably not OC related then. Most likely some software or background process crashed.

How long should I run XTU before I determine it's stable enough to stress for 8+ hours?

[ProKoN]

5 runs of cinebench r15

5 runs of xtu benchmark

Game until your gamed out or its bedtime.

8 hours of stress test while you sleep

Xtu stress test is fine but a bit weak. It's all I personally use

Try asus realbench for a good stresser

Ok, I'll try ASUS Realbench out see how it works.

[tlmills82]

Ok, strange.  I had 4.4GHz semi stable last night.  I was able to get through just about anything I threw at it. But today when I was planning on getting a 8 hour test in, it won't even get through 1 XTU benchmark.

[ProKoN]

Xtu benchmark is a good test.

Make sure you are on manual voltage mode

[tlmills82]

I was in Override mode (msi board) I assume that's what I need?

[tlmills82]

dialed it back to 43x, 1.25v vcore, 1.9v vin  35x Ring bus and 1.1v ring voltage and seems stable.

 

Now should I increase the ring bus multiplier then do initial stability again?

[ProKoN]

pass your 8 hour stability test first

 

treat the ring just like you treat your core as far as testing is concerned

[tlmills82]

@ProKoN @Faceman

I was able to achieve initial stability at 4.4ghz at 1.26v. I wasn't able to get the system to pass 1 benchmark at 4.5ghz below 1.3v (1.29 was the highest I went). I ended up just setting the ring bus back to auto because I wasn't sure I was really ready to get into that. Currently running 8 hour stress @4.4 on xtu. If it passes that I'll run asus realbench tomorrow while I'm working.

I started 4.4 at 1.29 and worked my way back. I got it down to 1.26 where it passed 5 xtu benchmarks and a couple cinebench ones as well. At 1.25 it would pass one maaaaybe 2 benches before I got "WHEA_UNCORRECTABLE_ERROR"

[tlmills82]

double post

[tlmills82]

@ProKoN

Well, I ran an 8 hour stress which it failed at sometime overnight...I ended up raising the voltage a few times and skipped 1.28 and ended up getting a stable clock at 4.4ghz and 1.29v.

 

Temps seem fine (I think), 26-30c idle, and maxed out at 71c during the 8 hour stress.

 

Not really sure where to go from here though.

oc your cpu cache or play some games
