Hi i have unlocked my X2 5000+ to quad core deneb and all if fine, very stable. However, i cant get it to OC past 2.5GHz. Ive talked to people who have had theirs running fine at 3.2GHz on stock air. What am i doing wrong? I downclock the memory to CL4 from CL5 and 667MHz down from 800MHz. HT link dropped to 8x. Raise bus to 235 from 200 and i get around 2.5GHz stable. If i raise it anymore system refuses to boot...Should i be increasing voltages? Also when setting up to BIOs to change CPU settings it asks if i want AUTO, Optimized, CPU+PCI SYNC or CPU+PCI ASYNC.....which of the sync and async do i need to select? Thanks

CPU+PCI ASYNC is better as it doesn't overclock the PCIe. Yes if the system doesn't boot you need to increase the voltage and you don't want auto for any thing.

Thanks for the reply, it is currently set at ASYNC as i suspected thats what it might be. What is a safe maximum vcore for this cpu? and is there anything else i need to change to be able to clock it a little closer to the 3GHz mark without it failing to boot? Thanks

This is news to my ears, didn't know there was an "Athlon" dualie that unlocks to an x4 Deneb with L3.

Sure there is, and at a fraction of the cost of a real Phenom. But i guess you gotta take your chances with regards to the reason the 2 unused cores were locked. Aiming for 3.2GHz ideally and i heard its possible to acheive this without touching the voltage no less.

No its a Deneb core.......unlocks to a Quad-Core Phenom FX-5000 (4x2.2GHz). See link below. Im wanting it closer to the 3GHz mark. Thanks

How did you unlock the CPU with a 630a?

The Asrock N68C-S has a UCC (Unlock CPU Core) chip. Simply "enable" UCC in the bios and locked cores become active. Great feature for the price of the board i must say.

nice =)

I thought you had one of those old 630a's that sell for around 30.00$ on ebay ..

I have a few Asrock boards myself and they are just simply awesome for the price ;)
