Can anyone help? I have a AMD Phenom II x2 555 cpu(Black Edition). When running CoH in dual core mode everything is fine, but when i unlock the other 2 cores, the game flickers then shuts down when i try to play it. Not sure what the problem could be , so any input would be appreciated.

Thanks

This is the problem with unlocking cores on CPUs. The extra cores aren't always stable. If they were, they'd have been binned under a different part number.

Also, are you running the stock heatsink/fan? If so, it's possible that the one you've got isn't sufficient to dissipate the heat from all 4 cores.


Clicking on the linked image above will take you off the City of Heroes site. However, the guides will be linked back here.

As Hyperstrike already said... you bought a dual-core... not a quad-core.

"unlocking" cores not enabled on a processor is generally considered a BAD IDEA given one of two reasons:

Reason A: already cited by Hyperstrike, the cores probably didn't clear quality assurance and were disabled on purpose.

Reason B: those cores are not there. Later versions of a chip can use a different die-setup, so it's possible that your chip only HAS two cores to begin with.

Keep in mind the original supplies Phenom II X2 555 Black Editions hit the market well over a calender year ago ( January 25, 2010). The original supply of chips that had "fully functional" cores has likely already sold through. You probably won't be finding any modable 555's on the market now.

Oh, and before you state "but it's a BLACK EDITION!"

All Black Edition guarantees you is that the Clock Multiplier is unlocked, thus allowing you to change the clock-speed by using the clock-multiplier.

Black Edition processors do not, have not, and will not guarantee you extra processing - cores.
