Post your i5 2500k / i7 2600k overclocks!

[leezaal]

current settings 4.4ghz at 1.31v 31c idle - 51c full load

8gb g skill ram at 1600mhz 9-9-9-24 1.5v (default)

had to put vtt at 1.1 otherwise any overclock settings just freeze bios up.

 

If i leave voltage on auto it wont post never mind boot up at 4.5gh or higher

tried manual voltage upto 1.4 but bios froze up

tried running ram at 1333mhz still freezes up

 

any advice would be appreciated

It freezes at BIOS? What motherboard and CPU?

[leezaal]

Gigabyte P67A UD4 B3 with i5 2500k voltages and temps are fine but what ever bios version i run i get the same thing.

can boot into windows at 4.7ghz and it runs fine but when i power off and back on bios loses settings and freezes up.

but it doesn't do this at 4.4ghz

[El_Capitan]

There's a setting or two in the BIOS that protects the system in case of high temps. Turn those off and try rebooting and see if that fixes it. Otherwise, I have no clue what it could be.

[leezaal]

those settings are already turned off and max temp is only 51c

Try checking the Gigabyte forums. Maybe someone had the same issue before and it was resolved. I never had that happen to me, so I've no clue on how to help.

[leezaal]

FIXED: now running at 4.7ghz and 1.39v - 1.43v depending on load.

CPU PLL in bios was set to auto i thought that meant it was enabled

but it was not so i enabled it and it all works fine now.

amazing OC what settings did you use in bios to achieve this ?

Well, I had a new build to use for another workplace, and this time I went with a microATX build and undervolting to get the temps down on an i5-2500K. My goal was to have a powerful enough system for work, but somewhat portable as well.

 

CPU: i5 2500K @3.8 GHz 1.140Vcore Antec KUHLER H20 620 Pull (12v) Max 72C Prime95

MB: MSI Z68MA-ED55

Memory: 4 x 4GB G.Skill RipJaws X F3-12800CL9Q @ 9-9-9-24-1T

Graphics: GTX 460 1GB MSI Cyclone (stock voltage) @ 860/1720/2100 @ 0.975v Max 69C

SSD (OS/SQL/Visual Studio): Corsair P128

PSU: CORSAIR Professional Series AX750 Gold

Case: SilverStone Micro ATX Desktop Computer Case with Carrier Handle SG04B-FH (Black)

 

1.136V's at 3.8GHz with temps never reaching above 72C with an Antec KUHLER H20 620 in a pull-only config. Unfortunately, the case isn't as good as I thought it would be to put the radiator in a push/pull config. I was originally wanting a HD 6970 in there, but no way it would fit, and it's overkill, anyway (same with the PSU, but oh well).

I need to get some new screenshots up, but here's where I'm at with my 2500k.

 

CPU: Intel i5-2500k

24/7 Overclock: 5.0Ghz @ 1.37v / 1.38v loaded (20 pass LinX stable)

Bench Overclock: 5.3GHz @ 1.47v / 1.49v loaded (3DMark11 / Vantage Stable)

 

Other critical voltages:

24/7 Overclock: QPI/VTT @ 1.1v, CPU PLL @ 1.64v, VCSSA @ 0.935v

Bench Overclock: QPI/VTT @ 1.2v, CPU PLL @ 1.72v, VCSSA @ 0.975v

 

In both cases I'm running my GSkill Ripjaws X DDR3 1600MHz CL6 set @ 2133MHz 7-10-8-7 1T @ 1.58v

 

My 24/7 temps max out at 60C on 2 of 4 cores during a 20 pass LinX test. The other 2 cores reach 58C during the same test. I'm using a Gigabyte P67a-UD4-B3 board with the F3D BIOS. I don't use a manual vcore because the vdroop under load is too great and causes major stability issues. I strongly recommend anyone using this board to use DVID offets to get the vcore their looking for or need.

 

Ask away for any questions

My 2400 is running at 3.9
