Overclocking an i5 2500k with ASUS p8z68v-lx to 4ghz, Help!

post #1 of 10
Thread Starter 
Hey guy's so i've just upgraded to an i5 2500k, alongside this i bought a CM Evo Hyper 212 Air cooled cpu fan. Now this is my first ever overclock so i was wondering if anyone could help me set it up in baby steps? I'm firstly only aiming for 4ghz which isn't much in comparison to other builds with the same fan. So can anyone who is familiar with this board tell me all of the settings i need to apply in the BIOS menu? Voltages, settings etc. I just want to make sure it's all stable and set up correctly so if anyone could impart some knowledge upon me it'd be much appreciated, thanks guys!

My Specs:
i5 2500k w/ evo hyper 212 fan,
Asus p8z68v-lx mobo,
8gb (2x4gb) corsair 1600mhz ram,
evga gtx 660 ftw 3gb GPU,
OCZ 750w psu

cheers, look forward to your suggestions

Do not bump 20minutes after the creation of the thread lol.. Maybe 24h after biggrin.gifbiggrin.gif

On my side, i just done my first OC these days. All i have done, i put the multiplier manually to 48x (and let the BCLK to 100, per default), to make it 4.8 Ghz. Then, your cpu power. I have change my cpu voltage mode from "per default" to "Offset mode", then putting in a 0.350 Offset (this was the higher choice on my board). Everything Booted fine.

I would say, first put some voltage mod (if not by using an offset, put it manually (see with others)). On my side, I have changed my cpu voltage mode from "per default" to "Offset mode", then putting the midchoice of my offset, which was 0.200 or 0.250. Then, i put my multi to let say 44x (which i estimated was middle too). I booted to see if there is any BSOD. I had chance, my first setting was OK (no bsod while loading windows). If it successfully booted, halt everything now. Put +1 on your multi and try again. When i saw i was getting BSOD, i just upgraded the Offset by one (by 0.05 in fact) and let the multiplier like it was when you got BSOD. Ttypicaly, 0x124 BSOD means you need more power. I did these test to the 48x multiplier and the maximum offset i can give. It is pretty stable after 12h of Prime95, some playing, etc. If i down the offset by 1 (0.05), i get bsod. I guess this is the higher overclock i can get, without playing with BLCK, LLC and VDROOP (do not begin by changing these. This is only for past 4.8 to achieve let say 5.x Ghz smile.gif But read and be carefull if you do).

Here was my experience of my overclocking... I think this was the best way to help you biggrin.gif


Give us some feedback hehe.

Here is the guide I used when I first started overclocking my 2500k.

http://www.overclock.net/t/1100100/info-intel-2500k-2600k-overclocking-tips/0_50

Going for 4ghz, you should easily be able to do it on stock voltage with just a multiplier of 40.

Here's my favourite beginners guide to overclocking. The guide is about Ivy Bridge chips on a Gigabyte board but exactly the same stuff applies to Sandy Bridge, nothing has changed.

http://overclock3d.net/reviews/cpu_mainboard/gigabyte_z77_overclocking_guide/1

If you follow that guide you should be able to hit 4.4GHz at least. If all you want is 4GHz then all you will need to do is bump up the multiplier to 40 and you're done, no need to change any voltages or anything.

I quickly checked this guide and it seems to be really nice and complete. I would suggest it, Shortpegs ! (yes, i did read the AndyM95's post before typing it redface.gif ).

Have a great afternoon, i am out (of work) !!

ehm, i am pretty sure it's "safe" to use 1.3 to even 1.4v on the core on the Sandy chip. So yes, things have changed.
But all in all, a pretty nice guide, for Ivy.

Forgot to mention that... apart from the voltage tolerances wink.gif

How did you set the whole overclock ? Voltage, temp ?
