Oh Yuck. What a pain! Have you checked that the sticks are all seated properly yet? With any luck you'll find one that needs a little push back in its slot.

Hey ramsey, what temps are you getting under load at 4.6 with that heatsink?
post #423 of 6491
Hottest core I have seen is 65c while running IBT. I am using a push/pull setup on my Hyper though, so that helps. There are screenshots in one of my albums in my profile if you wanna see them. Love my little cooler.

Edit: My rig is in the basement with ambients around 20c.

Hey guys,

Just got my 3820 this week, and I finally have some time to get into OCing this thing.

Cept I have no idea what all this stuff means anymore. Why can't it just be FSB and multis?!

I have an X79 board with UEFI.

I'm looking at the OC interface, and here's what I see

CPU Clock - Auto (Choices are 100MHz, 125, 166, 250)
Host Clock (1/10 MHz)
Fix Ratio Override (Multiplier?)

I can't really get any good basic info anywhere. I feel like kind of a tard cause I can't figure this out. Last time I overclocked was when it was just changing FSB and vcore.

Now there's all kinds of variables.

Where to begin?!

125 with 1.35 voltage to start. Most take 1.36-1.38 to be stable. Use xmp to do your ram if you want.
post #426 of 6491
So put the CPU clock to 125, leave everything else alone, and set vcore to 1.36ish?

Strap at 125, multi at 37, vcore around 1.35-1.38, memory at xmp profile. Leave the rest in auto. All of this for a 4.625Ghz.

Hi everyone,

I am a fairly new enthusiast just beginning to OC on my 3820, I have read most of the posts in this thread, but still have a few unsolved problems that I need help on.

Currently running 125 * 37 (Should be 125 * 36, but my MOBO always add 1 more multiplier) @1.332 Vcore, during IBT, my core temp often fluctuate as much as 10 degrees, going anywhere between 49-59 degrees on the hottest core, same thing happens to my GFlop, going between 91-103.
What really worries me is this is not a gradual fluctuation, one second the core reads 50 the next it's 58. Same thing for IBT, 3-4 100 runs, then all of a sudden something in the low 90s.

IBT says my system is stable, but I'm skeptical looking at the results, please help me.

What cooler, case and tim are you using?
post #430 of 6491
H100 and Antec 900, I modded the side panel for the cooler.
Just ran IBT twice again, same thing is happening to temp, first run failed, second one is a little more consistent here:
