Trouble Overclocking my i5 2500K

[ANN1H1LAT0R]

Hey everyone,

I've recently just bought myself everything I needed to create myself a gaming rig and made sure (or so I thought) that I'd have the power and components to overclock and get that bit of extra gaming performance for my games. However I dont seem to be able to get myself a stable overclock. As Im new to the overclocking scene I was hoping for advice and comments to help me out

First of all the system I have:

Motherboard: Asus Sabertooth P67 B3 Rev
CPU: Core i5 2500K
CPU Cooler: Corsair Hydro H60
Memory: Corsair Vengeance 8GB (2x4GB) DDR3 PC3-12800C8 1600MHz
PSU: Coolermaster Silent Pro 1000W
Graphics: MSI GeForce GTX 580 OC Twin FrozR II 1536MB
Sound Card: Asus Xonar D2X 7.1
HDD: OCZ Agility 3 120Gig
Case: Coolermaster HAF 912


Now once I'd built the system I got this baby running perfectly at stock speeds (after making the sure the memory was runing at 1600 and not 1333 like the motherboard decidiede to swet it at) and in games and apps it runs perfectly with no crashes or blue screens. Im currently playing Battlefield 3 (everything maxed out) super smooth, Skyrim (maxed out) once again super smooth and Crysis 2 DX 11 patch with that high res texture pack once again all maxed out (crashed to desktop once but think that was the game and not the computer going on stability since and of other games)

So after a week of gaming and no major issues I decided to over clock the system. I used the AI overclock in the BIOS which apparently adjusts settings to get to a stable overclock and the system settles at 4.3GHz. In Windows 7 this is absolutely fine. Everything registers as it being at 4.3 so I ran my games. Skyrim keeps quiting to windows and Battlefield 3 blue screened several times. I reset the BIOS settings to factory and eveything else runs smooth again.

I read Custom PC who overclocked the i5 2500K on a Asus MB and used those settings to get 4.5Ghz with all the voltages and settings and once again games crash and bluescreen.

The CPU apparently never goes above 34 degrees (21 when idle in Windows). The GPU does peak at 88 degrees when gaming for intense amount of times (when the CPU isnt ovelcoked obviously as I cant game for intense sessions overclocked currently lol) so its not cutting out due to temperature levels so I don't know what to do.

The settings I tried using for the overclock were found here

Can anyone please advice me on what Im doing wrong and what I need to do to get a stable overclock. I really dont know what Im doing to be honest haha

All time and help will be appreciated

Each chip and board are somewhat individual so it is possible that with your cpu and board your highest stable clock is somewhere south of 4.3

I would have thought that 4.3 (at least) would be possible tho.

I'm NOT an expert and I got mine running quite easily @ 4.2 (at which level I'm happy - reasonable overclock running low volts ) so I'm sure that you can do same or better.

I run the same chip but an Msi board so settings I use would not be of much use to you - sorry.

Best advise I consider I can give you is read up thoroughly about clocking Sandy generally, then your board (and ram) and then start with an overclock that should def. be attainable e.g. 4ghz.

Get it stable at that level then play with the voltages - usually best (although not always) to use as little as possible.

THEN go for your further clock - as by that time you will have a good idea as to what and why etc.

Good luck

P.S. I read Custom pc myself - my view of their overclocking is , in summary, (usually) TOO MANY volts!!

Could too many Volts be the issue. I thought the only issue to using high Volts is heat. My understanding was that more volts will give a stabler overclock as long as you can get rid of the heat. Am I wrong on this thinking then lol

Probably not causing your problems but ...

Wiki link explains matters much better than I can

bf3 is an odd game

my hardware was stable in everything until bf3 came along. had to lower gpu clock and up volts in bios for cpu to get the system stable for it



and also too many volts will not make it unstable, only hotter

4.5 is achievable at relatively low voltage for the vast majority. Have a read of the first 2 posts HERE which should get you up to speed on overclocking your board and avoiding those BSOD's
