cacoe Posted November 26, 2012 Share Posted November 26, 2012 Early last year I bought an AMD x2 555BE 3.2ghz I'd initially hoped to unlock an extra core or two but I never managed to do it. No matter what settings I chose, my pc simply didn't boot. Just wondered if there's anything I'm missing, if I need to do anything extra like disable cool and quite, stuff like that? I felt like giving it another go since it's been so long. Thanks for the advice.. By the way, the mobo is a MSI 870a-g54 Link to comment Share on other sites More sharing options...

Astra.Xtreme Posted November 26, 2012 Share Posted November 26, 2012 I guess the first thing to ask is do you have the latest BIOS? Seems like quite a few people with that mobo have the same problem you're having. Some people are saying that if you increase the CPU voltage a little bit, it might work. And then some others are saying that there is only a 70% success rate for unlocking, so you might just be in that unlucky 30%. Link to comment Share on other sites More sharing options...
cacoe Posted November 26, 2012 Author Share Posted November 26, 2012 What would be a safe level to increase the CPU voltage to? Not all CPUs can be unlocked successfully, they're generally disabled because they didn't make the X3 or X4 spec stability I know this can be the case but from what I've seen, instability is generally the problem, my computer won't so much as reach POST Link to comment Share on other sites More sharing options...
cacoe Posted November 26, 2012 Author Share Posted November 26, 2012 Just updated bios, tried to unlock again. All I get is all my fans running at 100% and a CMOS reset required! Link to comment Share on other sites More sharing options...
Astra.Xtreme Posted November 26, 2012 Share Posted November 26, 2012 I guess start by incrementing it by 0.05 ~ 0.10 volts, and see if it will boot. I believe you generally shouldn't exceed 1.5V unless you're overclocking. Maybe you can try unlocking only the 3rd core and see if you can get that far.

cacoe Posted November 26, 2012 Author Share Posted November 26, 2012 I honstely think the feature doesn't work on this board at all. If I enable Core Control and manually disable core 2 (only two cores show at this point), I get the exact same problem, all the fans just spin up :/ Link to comment Share on other sites More sharing options...

cacoe Posted November 26, 2012 Author Share Posted November 26, 2012 Give MSI a shout and ask them if there are any known issues using that feature with your board Thanks, I'll try that. I do have a feeling they will simply say that my CPU must not be unlockable though. On a plus side, I managed to get a stable overclock to 3.9Gghz but I'm too scared to keep the voltages as high as they are!
