Hello Community!

AMD Phenom II X6 1100T Black Edition 3.3Ghz CPU
Corsair XMS 8GB PC10666 DDR3 1333MHz Kit (2x4GB)
ASUS Crosshair IV Formula AMD 890FX AM3 MB
Seagate 1TB LP Serial ATA HD 5900/32MB/SATA-3G
XFX Radeon HD 5850 1GB DDR5 BLACK EDITION
Cooler Master HAF 932 Case w/ Extreme Power 700w
Corsair H80 Water Cooling System

Like the thread says this is my first time overclocking, and after doing some research boy am I glad I picked a black edition! I overclocked my CPU from 3.3 GHz to 4.1GHz. I have ran Prime 95 for over 5 hours and I'm getting an average temperature of 57 C. I went into my Bios and the only changes I made were to my core multiplier, i believe i set it to x20 and my computer keep crashing at bootup so i kept upping my voltage by 1 until it became stable enough to run Prime 95, and had to up it some more till Prime 95 could stabilize.

My main questions are about temperature and volts.

My temperature readings are as follows:

CPU Temp - 57C @ 100% load using Prime 95 for over 5 hours
North Bridge - 54 C
South Bridge - 46 C


Voltage readings as follows:

Core Voltage - 1.536v , does this seem a little high? It would only stabilize at this voltage.
CPU/NB - 1.17v , do I need to up this for any reason?

Thank you very much for the help!

Temps look good but core voltage is too high for my tastes. (Double check your temps BTW. HWmonitor was reading my temps low by >10C)

I wouldn't go past 1.45 volts personally. (Even if it meant backing off the clock a bit)

When I overclocked my 1045t to 3.4Ghz, I never messed with NB voltage.

I've read many post that a 4.1 is a fairly easy OC, why is it that my volts need to be so much higher to support it? Anyway I can fix it?

I'm starting to wonder if any of the auto clocking utilities could be causing this issue...im pretty sure its deactivated though

6 cores at 4.1Ghz is an impressive OC. -Not something I would consider "common".


A 4-core Phenom II is more common to find overclocked to 4 Ghz. 4.1Ghz would be a lot easier with fewer cores.

I guess that makes sense. I'll just downclock till I'm stable on 1.45 volts...oh btw is it normal for volts to increase when running a stress test? Should I worry about 1.45 on the bios screen, or when im running Prime 95.

Sort of both. There is normally a spike between the moment you stop loading the CPU and when it idles down. If it's a really big jump, (like if it jumps over 1.5v at that moment) I would increase LLC and decrease voltage. The net effect, once "tuned" should be less gap between full load "droop" and off load momentary spikes.
