post #2771 of 6497
Hi, just finish my new rig, Rampage IV Formula and a I7 3820. Easy to overclock with 37x125 with 1.37v. But I dont know why , im unable to set a multi below 37. I entering 35 and change for 37, I'm stock with multi between 37 and 44. i flash to the last BIOS.

Any idea??wheee.gif

Only worried that the cpu died from something wrong with the RIVF. Cause I know I did not kill it myself.

Edit; if I post the batch code from the 3820, will anyone here be able to tell if it's from a decent batch?
Yep post it thumb.gif

first overclock with new Costa Rica cpu.
Did not even break a sweat.
Same settings as the Malay chip.



Oh and this chip has more even temps than the last. All cores are within 1-2c of each other. Not like the dead one that had two cores +10 hotter than the rest.

Atm the TIM is curing so I cant say for sure, BUT this chip does look hotter than the last one.
Was getting better idle with old chip Malay compared to the current Costa. mad.gif

Does anyone know the correct amount of preasure I should use on my Koolance 380i?
How far should i screw down the mounts?
Till they bottom out or a happy medium?

Can not find anything anywhere about correct mounting of that 380i block.

What is your delta temps, idle & load? Mine is 7C for idle & ~30C for load (4.5GHz) (43 - 44C when stress).

I think "standard" procedure apply; until you can't screw down anymore using your bare hand & before the mounting bracket start to bend.

That's bc 36 is the stock non-turbo speed. Anything below 37 doesn't make sense, and 35 would be downclocking. I think I got my answer!!

Glad you've figured it out. thumb.gif I've never put multi below 37, so no idea how it will behave when inputting lower than 37. tongue.gif

Have figured out why idle temps are so high on this chip.
Seems I had all C-states set to auto not enabled. With enabled my idle temps dropped 3c-4c. Power usage at idle went to 25w from 60w.

This chip is handling lower voltage than my last one did.
I have a stable 4.6ghz @ 1.325v and no signs of instability yet.
Going to keep lowering it till it crashes.

Will go for a 5+ ghz overclocked tomorrow sometime. Be good if this chip continues its current trend of needing less volts. Might be able to get 5ghz @ 1.4v or less.

How low can it go....



4.6ghz @ 1.3v



And now 4.6ghz @ 1.26v in bios wheee.gif
My last Malay 3820 would not even boot into windows at this clock & voltage.
Going to run Prime95 over night while at work and see if it holds its stability.
