Well guys, I am debating on whether to purchase this processor or to go with the i5 3570k.

I have posted a thread and just recently updated it here and I am looking for advice from some of the 3820 owners. Would anyone mind helping a brother out thumb.gif ?

Ok, here is a bizarre one with case on its side (horizontal) my temps at 4.3 Ghz at Prime95 load are 64C and I am very happy with this from a Hyper EVO.
But, If I turn case vertical (normal tower position), then within 2 minutes the temps shot up to 80C
And if I put case back to its side position and restart Prime95, the temps return to normal 64C at load.

Anyone have an ideas on this?

Whats most likely - defective MB that has backpanel plate not working to sustain weight of Hyper EVO cooler. Or that the cooler itself has bad mount and is defective?

The screws to motherboard are fully tightened and when I try to wiggle the cooler it does not give and is very snug to cpu.

I know that with Hyper EVO that there is this tension screw in middle and perhaps it is giving too much when case is vertical.

SOLVED, getting 56C now at Prime95 load, very happy now:

Here is my latest. Was able to tighten the memory a bit more.

Sorry for the messed up top one.

Temps are a little bit higher than I want still. Gonna change some fans around this weekend to see if that will help. Still using the stock TIM from the H80 as well. Debating whether to go with indigo xtreme or coollabratory liquid ultra. Been running 24/7 at 4.6 with 1.28v I hope it stays that way!

Here is a question, I wish to try doing 125 or 105 Bclock strap and I know I will have to up the vcore. But I see mentions of PLL Voltage, VCCIO & VCCSA. Do these change manually or do I not worry about these and just up the vcore and leave rest on auto?

Also I am seeing it stated in guide that if you use bclk strap and want power save to kick in at idle, the one must use the vcore offset and not manual vcore setting. Is that true? I see some just saying that leaving C1E enabled will be fine even when using a bclk strap. Or does this vary by MB brand?

hmm, if thats true it will motivate me to use my Gigabyte's saved bios profiles. Keep one for running the encoding and then one for normal everyday usage.

After going through the RIVE with a fine tooth comb, I settled on these outcomes. I didn't bother to take pics, just the raw info. Maybe it will help some of you. These voltages were consistent with the two 3820's that I had tested.

4.3 = 1.22v
4.6 = 1.3v
4.75=1.345v
4.87=1.4v
5.0=1.45v
5.1=1.51v


I still need to dial the 5.1ghz clock some more, but I really don't want to spend too much time fussing around at 1.5v+. Temps however are excellent, even at 1.5v+ the chip doesn't break 73c. My 2600k at 5.2ghz@1.52v would hit 80c in contrast.

If you have these, would you mind posting also the (BCLK x Multi), and load temps. Also what cooler are you using?

that vcore seems in line with my UD5 and i3820 at (100x43) with a 1.236 vCore

It was all multi overclocks, with the 4.3 being a 100 blck strap and the rest 125 blck strap. Pretty straight forward for clock frequency.

Cooling is water, xspc raystorm to be exact.

trying OC now with 125x36 using bstrap 1.25
set vcore manually to 1.35 in BIOS and when booted into windows it showed in CPU-Z as 1.344 when CPU was idle
but when started Prime95, CPU-Z then showed vcore as 1.296

followed the settings in this guide.
http://www.overclock.net/t/1189242/sandy-bridge-e-overclocking-guide-walk-through-explanations-and-support-for-all-x79-overclockers

Why is the vcore going down when at load?

VDROOP ... To compensate for this swing you'll need to enable a higher LLC level.
