I5 2500k - Gigabyte Z68XP-UD3P Overclocking

Hmm well F7e is your best bet however, for 4.8ghz you'll need atleast 1.4v+ some have had to have it at 1.425 for 4.8 but this is upto you and i'll not be responsible for any damage to your cpu ;). Oh and use Intel Burn test LATEST version, if your system is stable with intel burn test that's far better than prime. Make sure your temps don't go over 77 in Intel Burn Test. Run 10 loops standard - high - Very high ( temps will be higher with IBT!)

I'm new to all this overclocking so be patient lol, anyway I've tried all the settings and I can overclock my CPU to 4.7 and I've left prime on for 24hours and had no problems my CPU tempreature only goes up to 55 with intel burn test running and prime and my voltage is at 1.356 under stress.
So if I'm right my CPU can be over clocked higher than this, but when I try 4.8 4.9 or 5.0 it just boot loops and I have to pull the battery and start again. Does the boot loop mean I can't go any higher? Thanks for any input.

Are you running it with water cooling? 4.7ghz only reaching 55c with IBT is very weird, unless it is under water. If it is water, amazing to see how much cooler it is then air.
 
Loaded the new bios and it booted to windows trying 5 with 1.350 then I got the blue screen of death, I then tried the same voltage with 4.9 this time I got the blue screen of death running intel burn test so I'm going to up the voltage damn this is getting addictive lol. I don't want to damage the CPU so I won't be going much above the voltage I'm trying now but 4.7 works well for me so I might end up sticking to that.
 
Hi Guys

First off big thanks to Neil79 who has made overclocking a very easy process for me. I thought Id report my findings just as reference and maybe you guys could give me some tips in case I messed stuff up.

Firstly my setup differs in 2 ways...I am using a i7 2600K and a Gigabyte GAZ68Ap D3 board which is much cheaper board than the UD3P( Bought a MSI mATX board cause I LAN a lot and wanted a smaller build but the Noctua made it impossible to fit the graphics card into the 1st slot and the 2nd slot is only 8x).
Corsair AX850 PSU, Noctua D14 and unfortunately since suppliers here keep only Corsair memory which is not comparable with my Noctua , I'm using 4GB of Apacer 1333 DDR3 until my GSkills arise(placing order tomorrow-should I go with the 1600 or the 18**???).

I have tested the 4.5GHz overclock.
Used exact settings , but managed to go get Vcore to 1.270 ...It ran both Prime 95 for an hour and passed 20 "rounds" of the Intel Burn test. But for some reason kept giving me BSOD in Battlefield 3 so upped the Vcore to 1.280 and its stable as a rock.

I live in Africa so its extremely hot here, but the temps I'm seeing are all n the 60's

Core 1 61c
Core 2 66c
Core 3 66c
Core 4 62c

There were 2 sec jumps to a maximum of 71c on Core 2 and 3 but they stabilize immediately to 66c again.

Do I seem good?
 
Hi guys

Firstly wanted to thank the original poster for taking his time and posting his settings:) I Have just got my z68xp-ud3 and 2500k and am using the settings on the first page. Everything seems to be stable @ 4.5 but my temps are going through the roof. Using real temp I'm seeing highs of 94 degrees when stressing with intel burn test. Looking at the temps through the gigabyte touch bios though its at 83 degrees. Which one should I believe? I'm using a gelid tranquillo cooler running at full and think I have applied the thermal paste ok. I did it by the blob method I had read about on here. Does the thermal paste need a little bit of time to bed in? Here's a screen shot of my temps :(

Edit to say that I have installed easytune as was recommended in the first post and my temps are now coming back at 83 degrees full load. Does this look ok? The cpu voltage looks a little high

Still to high that's some 4C above me and only 4.5 :(

I've got to 4.7GHZ at only 79C MAX intel burn test, generally though it's 76 and much lower in prime
 
How's it looking now? I've just installed a NH-D14 and has brought my temps down quite a bit. It's 25 degrees in my room too so wasn't cold. Going to try 4.7 next I think :)

Whoa....those temps seem a bit toooo high to me...running a D14 on a 2600k with hyperthreading on and the max I reach at 4.7 ghz is 73c! And thats highest temp...its usually 65 on all cores at full IBT at maximum... Need to post some screenshots tomorrow
 
They are 10 degrees or so less that what they were with my old cooler. Prime95 blend test max's out at about 71 so overall I'm pretty happy
 
Had two cold boots yesterday first time since last month over 20 days!, however on checking gigabyte they've removed the bios as faulty and gone back to F6!
 
Seem to be having a slight problem with mine. When in windows my computer is completely stable, stays at good temps and have run a burn in test for 2 hours on max settings.

Just seems that sometimes when I go to turn my computer on in the mornings it will occasionally not cold boot (Switches off mid turning on and then display's a message saying it failed to boot which may be due to overclocking) for no apparent reason seeing as I have already determined it is stable by running tests.

Have any idea what could be causing this. Sometimes it seems like its the monitor signal. If the monitor isn't turned on before the PC it pretty much always does it. But it will sometimes also do it when I have switched the monitor on before hand.

Thanks for any advice!

This is a common problem i'm afraid with gigabyte Z68/P67 boards, here's a tip!. When it shut's off on it's own as you boot up, pull the psu cable out for 1sec and put it back in. It should automaticly boot up on it's own and not shut off while staying stable. On the rare occasion it does it again, pull that psu cable out.

There is the odd member here who blame everything other than the board or bios just ignore em, gigabyte know it's an issue and have put out lots of beta bios's trying to fix it.
 
Thanks for the information. Guess I'll have to stick with it then. Only annoying part is it seems to reset my RAM frequency when it happens so I have to go into the bios and change it back each time which gets on my nerves xD. Apart from this it a really great board :/
 
I get a similar problem with my board but it only happens if I hit the reset switch. It comes up with an error and resets my overclock. Powering on normally is ok so I've learn not to use the reset switch
 
Hey Guys could you just have alook at my results. My BIOS recently reset and I'm having trouble getting good results which is annoying as my preious results were great.

I think they are ok but my VCore may be abit high but settings much lower than these causes BSOD error 124

I have my turbo boost set to 45x with a 1.30 VCore (Level 6 Load Line)
- 1.19 VVT
- DRAM VOLTAGE: 1.19
- TURBO POWER LIMIT: 300
- CORE CURRENT: 300

When running a burn test the max VCore I achived was 1.39 with the VCore mostly staying around 1.36. Ma temp was 70oC on air cooling.
Average burn in results were 126 Time and 121 Gflops (20 runs). Will post pictures when I'm back from college.

What do you guys think of these stats. My system is stable but I still think my VCore is quite high.

Thanks for any feedback/information on this!
