I'm completely noob on overclocking but just built myself a new rig. And had off course try to unlock extra 4 core, with the asus core unlocker switch on the mobo. In bios it says it's a Deneb B50 (i think it was) with L3Cache. And it says 4 cores activated! when asus green screen shows. But when I try to boot up it freezez loading windows. Tried increase the voltages step by step cpu 1,4v - NB Cpu offset to 1,2v (From 1,3250v - 1,1v) but still the same freeze. Guess I was'nt that lucky after all. I even tried the manual core locking (locking core 4,5, and) in bios but still same freeze. It allmost feels like it is the automatic core unlocker switch that is making the comouter to freeze.
Anyway as I said i'm completely new to this oc'ing and this is the first time I'm doing it, so did an auto tuning with Asus TurboV Evo (the turbo key II switch on mobo is not on).
My setup is this:
Case: Antech Six Hundred (original fans + one extra 120mm input fan down in the front)
Gpu: onboard HD4250 (saving up for a HD 6850)
Psu: Chieftec Super Series 650W PSU 140mm fan (Modular)
Cpu: AMD ATHLON II x450 3,2Ghz
Stepping: C3 (Revision BL-C3)
Frequency: 3,612 Ghz
CPU voltage: 1.3250v ( 1,428v under load)
NB Frequency: 2330,4
NB volts: Auto
RAM: Corsair XMS3 DDR3 1600MHz 4GB CL9, Kit w/2x 2GB XMS3 modules, CL9-9-9-24 1T
Motherboard: ASUS M4A88TD-V EVO/USB3
Cooling: Air cooling / CoolerMaster Hyper 212+ (thermal paste that came with)
OS: Windows 7 Ultimate 64 bit
I'm reading up on how to overclock in BIOS but not shure yet since multiplier is locked I have to increase bus speed and that affects the memory aswell I've heard.
First pic is prime95 stopped, second is running again to show frequences under load.
Please correct and advice me if something is wrong, need more info or have some tricks or tips for me!
