X2 560 BE - Problem Unlocking All Cores

post #1 of 21
Thread Starter 
My sig shows my current rig. Using that MSi board I was able to unlock my 560 to a tri-core. When I first used the Core Unlocker feature it did unlock all 4 cores but I would get a blue screen at the "Starting Windows" screen. I figured out that the #2 core needed to be disabled in order to get the other 3 cores working in Windows. What can I do to try and see if I can get all 4 cores stable? How high can I safely set the CPU volts and CPU/NB volts? Also is it odd that the #2 core is giving me problems? I thought that is suppose to be one of the two original cores that the CPU was meant to use without unlocking.

Core might just be simply unstable. Remember, unlocking is a bonus only.
You shouldn't have been trying to unlock all (4) cores with that mobo though, that's basically like spelling a death sentence for yourself. That board is well known for VRM failures with high TDP (4 cores & 6 cores) processors.

The cores are numbered 0,1,2,3.

Only 3 cores might be good. Add a a step of cpu and cpu-nb voltage and underclock if you want to try to boot windows, but if you can't get it to work the core could probably just be bad.

You could see how well it clocks as a triple core. That's still a bonus over the X2. Max voltage depends on who you ask here, I'd say keep it 1.5 and under but it depends how long you want it to last.

A rule of thumb i figured out to know it you have got 4 stable cores is this. If you can't get all 4 stable with 1.4v more than likely 1 or more of the cores are actually faulty. Having said that, the max safe air cooler voltage is 1.5v and water is 1.6v

Sometimes increasing CPU voltage may help stabilize a core. But with such a board, you definitely don't even want to try overvolting on a 125W. This is why unlocking is even more risky than just straight up running a 125W quad core.

Likely just a defective core.
You could try a bit more voltage for stability but it's generally hopeless.

Consider any core unlocking as a bonus.

The 'true quad core' design of these chips negates that. If AMD had to throw out all chips with a bad core 0 or core 1 core, it would be a huge hassle, versus simply locking them and using the other cores which function properly.

What a shame that MSI advertises this board, and many others, as being able to overclock and to unlock cores yet they aren't designed well enough to handle it. With that being said, would you guys think that it would be OK if I just run my 560 as a tri-core at stock settings? I just need it to last for a couple of months until Bulldozer comes out.

Dude, you bought an X2.
The other 2 cores can either be bad, or be good if AMD had particularly good yields or the demand for that certain product line was higher than expected.

The only person you have to blame is yourself.
Anything more than an X2 is a complete bonus, the chip as you bought it was advertised as having 2 functional cores, and that's exactly what it delivers.

Should be fine as a tri-core.
If you have problems, simply disable ACC and use it as a dual core.

Tri-core at stock settings should be ~95W and fine. I usually consider unlocking as a bonus only as well. MSI disappoints sometimes, I know frown.gif pretty much all of their 2010 AMD boards were really crummy, but this year should be a much better year for MSI, they're already working on releasing much-improved AMD boards smile.gif

guys want to help me try and get my cores stabled? I pretty much got the same thing the BSOD. But I want to try and up the vcore, I took a gamble but I'm not ready to give up hopefully a bump in the vcore might help. Either that or I make another 2 hour trip to microcenter and get an x4. I should have just gotten the 1055t
