Please. Need Help on OC a E6420 on an ASRock P43DE

[BlackShark77]

Hi

I am sorry but am a noob to overclocking, but not to computers, I am a senior IT/NETWORK support engineer for over 10 years. Having problems getting a little more juice out of my E6420 its aging but am sure I can do a little better as its really the only thing i feel is dragging my system down interms of gaming performence. and with Windows 7.

ASRocks bios is a little confusing compare to asus or gigabyte and I really cant afford to fry my CPU but even a minimal overclock to say 2.8 would be good enough for me.

Any help anyone can provide will be grately apreciated.

My system specs are as follows:

Core 2 duo e6420 @ 2.13 stock (Artic Cooler freezer 7) @ 54C /129F idle

ASRock P43DE Motherboard

6 GB of Patriot 6400 MEM at 4.4.4.12 CL

XFX 4870 XXX OC 1GB

THERMALTAKE PSU 750W

WD BLACK 750GB 7200RPM 32MB

Dual Booting Windows XP Pro anf Windows 7 Ultimate

Things Ive tried using OC tuner asrock provide for Win 7 from settings gleened off youtube...

Adjusted CPU voltage to 1.40000 from 1.35000

Adjust CPU Multiplier to from 6 to 8

then incremented FSB slowly by 5 and reached 285 before BSOD, and acording to the youtube video the FSB should have been 400 to get 2.8 but I cant get no way near, and am afraid to change bios unless I have some concrete safe overclock recommendations from someone more experienced, therefore Please Please Help if possible, Many thanks in advance and let me know if i need post any further information,

Thanks

Hi BlackShark77.

i overclock with my cpu voltage on auto and it works fine. and also in order for 2.8ghz on 8 as multiplier u only need 350mhz fsb. 350*8=2800. but the problem is that u get BSOD at 285 FSB. try setting the voltage on auto and reply on wat happens.

The VCore on the e6420 is officially safe up to 1.5v, so you have a little head room to keep pushing and make sure that your memory is as close to the factory stock frequency as possible to rule out that as a cause of BSODs. By the way, those temps look a little high you should probably re-seat that heatsink or use better thermal compound. Contrary to what Drunkdrive said, you should never let the motherboard control the voltage. It either sets the voltage to high or to low.

Thanks for the reponse, sorry I have not posted in days, was away.

Right have got a closer diagnosis of the problem. The overclock holds fine in bios and is stable in XP, But windows 7 does not like the overclock, bios or done via software, get the standard irql_equals BSOD.

Software overclock bsod once commited/applied overclock of FSB. and Bios overclock gets same BSOD while booting.

I would be most grateful if you have any ideas.

Cheers
