MSI Lets You Unlock CPU Cores in Windows

AMD doesn't lockout cores for no reason they do it because one or more CPU cores on any given die doesn't pass Quality Control this is usually because the cores can't reach the operating frequency and temperatures without becoming unstable. Or one or more cores just won't work at all and that core brings the whole CPU down so they lock those cores out to keep them from being accessed by other assets on the chip and on the motherboard. For the price of a six core Phenom processor I'd just by the high end six core for less than $300bucks. Rather get six stable processors running at 3.2 GHZ with full L1, L2 and L3 Caches than get a CPU that you can unlock cores on that more that likely will bring system unstability problems.

If your building a basic system for non gaming then take the triple core and just leave it alone and don't unlock it because of the stability problems. Heck for web browsing you only need a single core. Free Cell works great on a single core celeron processor. LOL..

besides with a good triple core or even a six core processor you can put a high end graphics card to go along with 8 or more gigs of ram for a PC that will play games at high resolutions for literally years to come.



Actually It's done by lots, not one by one, that would take a millennium. Instead they test say 10 out of 100, and if the majority of those 10 fail then ALL are labeled as tri/dual. So no, this is a very good idea., as a vast majority of the tri and even the dual's work perfectly fine, they just get thrown in the few tested that most of where bad. Far -far- more likely to have a good one, then a bad one.



From what I've been told, the way that they lock cores usually ruins them, so the chances of getting a 2 or 3 core processor and unlocking cores without a problem is pretty low.  That, and if you unlock a core and it causes system instability, you just voided your warranty, so that's something to consider.  The best you can do at that point is see if you can relock the core and hope there wasn't any permanent damage done.

It's about  as much of a good idea as any other overclocking or changing of a system beyond what it's rated for: if it works, hooray, but if it doesn't, you're hosed.

It really comes down to if you're a bad enough dude to screw up a new processor.



"It was discovered that some AMD tri- and quad-core processors have additional cores that could be unlocked..."


Or is it supposed to be dual core? 



I'm guessing you'd have to reboot for Windows to recognize the cores you've turned on.
