i totally agree this chip is the best ive ever owned
post #242 of 6510
Running OCCT at 4.626 ghz and at 1.35 v I keep getting an error which shuts down the test at around the 20 minute mark.

This is in both the OCCT and Linpack test.

2012032410h10core0.png

Any ideas on what I should try?

Up vcore?

Edit: Been stable for an hour now at 1.38

This cpu clocks like a beast, running it on a R4E with a noctua NH-D14 with stock fans at 5ghz. Had a prime thread failure after about 20 minutes, so I raised my core voltage a bit (from 1.500 to 1.510, shows as 1.480-1.488 in CPU-z), seems stable now.

Edit: Had to raise voltage slightly more, it's at 1.496 now

Has anybody had any luck running 166mhz BCLK? I figured out my limit on 125mhz BLCK is at least 1.270v for 4.6Ghz. But with 166mhz BCLK i cant get it stable regardless of voltage, clock speed, or memory speed. Is there anything else i can tweak other than VCore to help?

Hi,

Rampage IV Formula
3820
Ram Ripjaw z 1866 4*4gb


i'm stable @ 4750(125*38) with vcore 1.345 (bios) and I can't stable my mems @2000, with 1333 it works stable.

any ideas?
post #248 of 6510
I would like to run 166 for the different memory dividers. Memory is 2133mhz but at 125 its 2000mhz. 166 gives the option of 2222mhz. I'm just curious devil-smiley-019.gif

Holy cpu degridation Batman, is that going to be your 24/7 oc? Because I read that the max volt for the 3820 before it begins to degrade is 1.4v, maybe I'm wrong but with those temps maybe not rolleyes.gif

Psh no. It'll be fine for at least a long while.
