My new 8750 BE is a really bad overclocker? - Page 2

Okay, this is driving me nuts.

My RAM is fine, I ran memtest with no errors.

I have it underclocked right now anyways.

I also have my HT underclocked.

Whether I'm at 250 x12 or 200 x15, prime is failing within 10 seconds, giving me a hard crash to a blue screen.

i hate to say it. but you might have gotten the unlucky chip from the batch .
i hope thats not the case tho. keep tweaking it. good luck.

I think so too.

I can't even get the stupid thing to be stable at 2.9 GHz.

The thing is, there are absolutely no signs of instability until I run prime.

I can boot at 3.2 GHz no problem, with only 1.46v. Everything is nice and smooth.

I turn on prime, and within seconds it hard crashes.

My temps are fine too, BTW.



With my 5000+, if it was unstable, I could usually tell before I ran any tests.

I also pulled out my 4 GB of PI Blacks and put in one stick of my Kingston RAM, but that didn't make a difference.




This sucks.

try running setting your RAM manually to DDR400 speeds in bios. leave the timings on auto. up the ram voltage to 2.1volts. set your Vcore to 1.4 volts.
your HT to 1.45volts and your NB(might say Chipset voltage in bios) to 1.5volts.
double check and make sure cool&quiet is disabled as well as virtualization. and slowly start upping your ref clock.
ummmm. stuff

What about the processor-NB voltage?

I've usually been leaving that on auto, or setting it to around 1.25v.

That one seems like a key setting though.



Edit:

I did what you said. I set my HT voltage to 1.4 (board doesn't recommend going over this) and my NB actually has 3 options under it when I set it to manual. I put what I think is the main NB control to 1.8v (won't let me go lower).

I also manually set the HT and NB multis so they are running at 1800MHz.


I'm running 1.392v 210x14 and it has been Prime stable for 10 minutes now!


Things are looking up.


My temps are 47C on load right now. (I'm using a Core Contact Freezer, not the Zalman in my sig)

awesome. almost at 3GHZ.

i dont know about your mobo. but on my biostar790GX the chipset voltage and NB voltage are the same thing.

nice load temps your getting too. heat wont be an issue.

keep it up. try dropping HT and NB multipliers to 1600MHZ and set your ref clock to 230. 230x14=3220MHZ and 230x8=1840 for HT link and NB

I have a southbridge voltage setting I can change, plus a northbridge option that has three sub-voltages:
one of them is the HT voltage, plus two other ones: the Core/PCIe Voltage, which I've been leaving on auto, and the other is the NB PCIE PLL which I have at 1.8v.


And on top of all that, I have another setting called Processor-NB voltage.

I don't consider myself to be an overclocking noob, but my mobo has an unusual amount of settings to begin with, never mind the new ones that were unlocked when I put this phenom in.

>_<


I'm going to give 215x14 a try.

It is a no go. I can't get anything around 3.0 GHz to be stable.

Lame.


(BTW, this chip is so incredibly fast compared to my 5000+ running at 3.2 GHz.)

processor NB voltage is the one you want to up. keep it as close as you can to your CPUvoltage/corevoltage/coreVID, whatever your bios calls it.

reminds me of my old 9850BE, it won't do 2.8Ghz Stable on my DFI mobo,

like to ask u tho, what's Core Contact Freezer

(SB600 does suck with phenom)
