i7 3820 - 4820 Overclock Club - Page 273

post #2721 of 6497
Wow people really are needing a lot of voltage for 4.6ghz.
Was playing around with my 24/7 overclock and have gotten a rock solid 4.6@1.335v in bios and 1.344v under load.
Thats with HT on and all C states enabled and energy saving features on.

Still have one weird core that is -10c cooler that all others. At idle it is even getting cooler than ambient and water temps. Which doesnt make any sense at all.

thx wookie

any idea of max vrm temps before they start throttling??? tempted to watercool
post #2725 of 6497
I cant honestly say as I have never had any throttling myself. I have 8 140mm fans pushing air into my case and a small 60mm fan cooling the back of the motherboad vrm location. Even under 5.1ghz load my vrms heatsinks have stayed only mildly warm to the touch and have never seen vrm temps higher than 60c.
I would guess they would throttle around 90-100c. Others here will know for sure.

hey guys.
i am wondering if any of you can help me push this cpu over 5 ghz, i am trying, but i have little success. it is air-cooled, lapped prolimatech super mega, lapped cpu too, on a rIVe. 4x4 mushkin redline 997007, with an enermax revolution psu.
what bios settings are you using for over 5ghz? 5125 and 5250? plz help. thanks in advance.
these are my current settings:
post #2728 of 6497
For 24/7 5ghz I am using 1.415v in bios. 1.435v under load.
I would start at 1.450v and see if its stable then work up or down voltage as needed.

linx stability with me asks more voltage. over 5ghz, with 41 multi and 125 strap, it just comes to the windows loading screen and stops, nothing happens. i am interested in going over 5, 'cause the thermals allow me to...
post #2730 of 6497
@ 1.464v and 5ghz still is not stable I would just live with a lower overclock on less volts personally. The chips are said to degrade at 1.4+ and i would hesitate to run more volts than you are currently.
