New Ram Won't Let Me Unlock PhenomII Cores?

[The Oven]

I bought a phenom II x2 555 black edition and biostar a780L combo.

I went with the am2+ board since I still had ddr2 ram, 2x1gb crucial ballistix 800mhz

It turned out that one of my old ram sticks was dead, so I was running with only 1 one gig stick installed.
I unlocked the cores in the bios and everything went smooth, ran prime95 for a few hours with no problems.
Windows 7 ran fine, I even managed to game a little at low settings for over a month and never had a problem with the extra cores.

A little over a month went by and system would not boot, I figured it had to be the memory so I went out and bought some ocz Platinum 4GB DDR2-1066 http://www.microcenter.com/single_pr...uct_id=0288096

I installed the ram, enabled acc and kept getting a no operating system found error

I put everything to default in the bios, got into windows and tried a clean boot

It solved the missing operating system error so I tried acc again, now the system locks when windows 7 starts loading, right after the little orbs start coming out of the darkness to form the windows logo.

I tried different settings on voltage and timings for the ram and nothing helped, I upped the voltage on the cpu and still nothing

The ram will also not run stable at 1066 even with the timings loosened so I know it is going back to the store.

So my question is:
Why is the ram stopping me from unlocking the cores and what ram can I get that will allow me to do so?

Keep in mind that I had both locked cores running fine for over a month so I know that they work.

Thanks

Only thing coming to my mind is a weak/defective memory controller on the processor, but it isn't too likely. You should try running with only a single stick of ram since that is all you used before.

In some cases, the chips they sell with locked cores have a CPU-NB/IMC that isn't stable when all the cores are enabled. My Sempron 140, for example, exhibits NB instability with one core unlocked that I just can't fix. It may be that you will be unable to boot in dual-channel mode. Try switching to single-channel DIMM slots, or just boot with one DIMM, and see how the unlock goes.

edit: ninja sort of beat me to it.

Amen to this. The few times I've used OCZ memory, I've had nothing but problems. They do make several quality products (including memory), but any of their lower-end kits (Gold, Platinum, Urban, etc.) tend to be of questionable quality.

You said you reset your bios is all your settings the same ? Sounds like it could be a ach setting or something also . Just make sure it not something else stupid am never seen ram change things like this.
