Specs: Windows 7, 2.7 GHz / 3327 MB
I am not au-fait with overclocking/unlocking, but have just bought a cheap new motherboard/CPU Combi £50.00

Motherboard Model: ASRock N68C-S UCC
CPU: Sempron 140 2.7 GHz 45 W July 2009 SDX140HBK13GQ Sargas Core

In the Motherboard BIOS I have enabled the UCC Option and now have a:

Athlon II X2 4400e 2.7 GHz Regor Core

I have googled and it seems to be satisfactory to do this, but would like a second opinion, thank you.

By the way I am using 2 x 2GB Crucial PC2-6400 Memory, which I believe is OK !

I heard energy efficient e series are good overclockers, may be u can try to push it further.

Thanks mickliq, the unlock is successful and has been running hard for 8 hours no problem.

Will read up on overclock options, but concensus is 3.2 to 3.4 is good to aim for....

How's your AMD overclocking skills? The CPU multiplier is locked from going above 13.5x but it can be lowered. As you raise the CPU frequency, it will affect ALL the other buses (RAM, HT, PCIe, PCI) - you're going to have to compensate so that they don't go too far out of whack.

I just downloaded the manual & had a look at the BIOS chapter. Do NOT use EZ Overclocking, enter all the settings manually. Try these settings to get you started:

Overclock Mode = Auto or CPU, PCIE, Async. (not sure which is best)
CPU Frequency (MHz) = 250
PCIE Frequency (MHz) = 100
CPU/LDT Spread Spectrum = disabled
PCIE Spread Spectrum = disabled
SATA Spread Spectrum = disabled
Multiplier/Voltage Change = manual
Processor Multiplier = 13x
Processor Voltage = 1.35v
HT Bus Speed = x4
Unlock CPU Core = enabled
Memory Clock = 333MHz DDR2_667
DRAM Voltage = set to RAM manufacturer's spec
Cool 'n' Quiet = disabled

If you can pull it off, the CPU will run at 3.25GHz with the RAM at 813MHz DDR & the HT bus at 1000MHz.

I just ran across an article from about 6 months ago, below is the "conclusions" page. It states some of the negatives about the board. But if you can unlock the 2nd core + overclock to 3.25GHz & it runs stably, I'd say you got a pretty good deal.
