kz9's Overclocking Adventures.....

Ok so now with a little more knowledge on this OC stuff, I have decided to post up some of my successes, but mostly failures....lol


Ok first off the rigs, so people know about them.


Gaming

Asus Sabertooth X79
i7 3930k @4.7GHz
Corsair H100
32GB Patriot Viper DDR3-1866
Asus GTX 580
OCZ 120GB Vertex 3 (os)
OCZ 120GB Vertex 3 (Games/Programs)
OCZ 120GB Vertex 3 Cached with a 2TB WD Cavier Green HHD
300GB WD HHD
Seasonic X760


24/7 Rig

Asus Maximus lV Extreme
i7 2600k @ 4.1GHz
Antec Kuhler 920
16GB GSkill RipJaw DDR3-1333
EVGA GTX 550 (2GB)
OCZ 240GB Vertex 3 (os/programs)
2TB WD Cavier Green HHD
1050w PSU - Enermax?


So I was told not to use the AI suite crap and use CPUID. I have that installed on both rigs now and I also got the 64-bit Prime95.

I was worried about the 24/7 rig as I bought it off a guy used. He said it wont boot and come to find out it was a bad stick of RAM. Replaced and OC'c it to 4.6GHz at first, then backed it off to 4.1GHz and it has been solid, and running Prime95 right now and core temps are around 65'C and Socket at 47'C.

I was at first confident in the Gaming Rig at 4.7GHz because of the fact I never got BSOD of frezze ups, except from a bad SSD. It would run games no problems, but I should have known this doesn't make it stable.

I installed Prime95 and tried to run that.

No go......lol

BSOD before it even started any test....lol

Sombitch, now I have to figure this out.....

So when do I know that Prime95 is done? It said I passed 768K? Whatever that means. Now its back to test #1. (24/7 Rig)

Mate don't waste your time messing around with Prime just yet.

Here is the golden rule of overclocking.

Before you even try and boot into OS run memtest Go download 4.2 for USB stick works like a charm.
Set your overclock in BIOS and pay attention to your memory settings.
Run the memtest with one stick at a time and then when all pass run the test again with one stick in a single ram slot, till you have had all your ram slots pass.
Only then do you put all the sticks into the slots and run memtest again with them all in.
If you pass then you know your OC is solid on the ram front.

2600K on the cooler you have 4.6GHz 24/7 no problem at all.

You could even leave all your voltages on auto to be blunt and should be good to go CPU wise.

But please do the memtest thing first.

I have done that before (you helped me) when I thought it might have been RAM, but ended up being my SSD.

I will try again I guess.

I wonder if it has anything to do with running that RAM cache with Supercache5?


The 24/7 rig passed PRime95 at 4.6GHz and temps on core were around 70'C (no higher)

Ok so I memetested again (ok), got rid of the RAM cache and also retweaked the OC to 4.6 and Prime95 is running now. No BSOD's yet, but I have core temps of around 90'C.

Is this normal? This is on the 3930k


Edit: FATAL ERROR:Rounding was 0.5, expected less than 0.4

Any thoughts? No BSOD's, just the testing stopped.

I found a good write up for a 4.7GHz clock on another forum. Lots of people are getting stable results, but most are complaining of high core temps. 80-84'C

Using the cooling solution you have stated those temps are correct. And 4.6GHz for that CPU is very good for 24/7

Does the over clock die on you when gaming or doing normal stuff? Prime stable just means prime stable nothing else.

Runs fine doing everything else. Never crashed before I started to do Prime.

Tried the 4.7Ghz clock that I found. Stable in Windows and everything else but prime95.

I think i am just going to set it back to my 4780MHz clock I had it and wait for it to crash if it does and then do something then.


I have ordered another set of fans for my H100 to do a P/P setup, and another two 120mm 2000rpm case fans to help keep things cooler. I also will be mdding the case on the top so I don't have any of the cross-members in the path of the airflow to the H100.

Feel like a have to bring this subject up (again)..

There has been people overheating their cpu's on h2o coolers, using non pwm fans..

All in good intentions.
