P5K Overcloking problem, few second freeze

Hey guys I have a problem overclocking.

Basically when I clock it to over 3.0ghz i get random freezes for like 3 seconds every min or so. I cannot pinpoint it to what it is. Mem test says my memory is fine.
I have the following setup:

CPU: E6600 Stock @ 2.4ghz
Mobo: P5K Deluxe Wifi
Memory: 2x1Gb Crucial Ballistix @ 4-4-4-12 timings (on 2.2volts)
Gfx: BFG 8800GTX OC2
HS: Thermal Take Ultra 120 with Scyth S-flex and Antec fan
PSU:HX620w

My temps are fine (idle 28-30 and lod 55ish) when overclocked to 3.3ghz. My voltages are fine, cpu voltage is auto in bios and pc probe, cpu-z and hardware monitor by cpuz people says it is at 1.45v.
Orthos is fine too, I run it in safe mode and I still get the freezes so I can understand what it is that’s wrong.
My bios revision is 0404.
Anyone have any suggestions on how to solve or a idea on what the cause of the problem is?

Thanks
Amrit

So, just so I understand about every 3 minutes it locks up but then resumes and everything is fine again for a few minutes? And this doesn't happen at stock settings?
 
nah it randomly freezes for 3 seconds.

Its happened at stock once before but never after that time at stock speeds.

I been told by soemone on another forum to try chaginging the sata cables around from a P5K one to one that didnt come with the P5K. So far it aint freezing up been about 2 hours now. Fingers crossed this solved the problem.
 
Hey everyone just wanted to update you all.
Looks like Clunks advice from Clunk.org on changing SATA cables around WORKED!!!
So far no freezing and I restarted several time during this time to make sure it wasn’t due to the OC.
While changing the cables around and messing about it also lead me to realise my airflow wasn’t good in the case. Normally with the 3.3 GHz OC I was idling around 30 degrees Celsius and using TAT to put 100% load on the cores it was hitting 60 degrees Celsius. This was with all 5 fans in my case (4 Tricool's and 1 Scythe S-Flex) at HIGH and a Thermalright Ultra-120 Extreme!!!(Yes it was a noisy beast lol!). Well when I took the case off I notice a drop in temprature of 10 degrees!! So I turned my top exhaust fan of the P182 to intake air and now, at 3.3 GHz, my temps are idling 25 degrees with all the fans in the case set to medium (20 with everythign on high)! It’s so quiet and cool now!! On load it’s around 50 degrees Celsius!!
Thanks for all your help!
