Phenom II x2 560 x4 confusion?

post #1 of 11
Thread Starter 
Hi all i recentley bought a phenom II x2 560 be and everytime it boots on m4a78lt-m it says "unlock all cores press 4" so i finally thought ok pushed 4 on boot and there you go. checked cpu-z and its showing amd phenom II x4 b60. now my question probebly a stupid one but i dont understand these things my motherboard supports a cpu upto 125w but on cpu-z it says max tdp 143w is that the same thing or am i getting mixed up if they are the same am i doing damage?? by running it at 143w when my mobo only supports 125w or are they 2 completlty different things?

As an unlocked CPU it doesn't read everything properly - there aren't any 143w CPU's Just run some stability test (Prime95 blend 12+ hours) to make sure everything is good, you might need to raise stock voltage in order to get everything stable, but it should be good going from there

It can be an 140W if it's a C2 revision.

OC can always to damage to the life span of hardware but depends how hard you want to push

I was running an x2 550 unlocked to B50 @ 4.0 with 1.5v for twelve months and never saw any issues with a MA785G-UD3H or with a 890GPA-UD3H I had after that.

Really have nothing to worry about but you need to stability test your chip once unlocked to make sure the cores are stable as some times they are locked out because 1 may be faulty, luck of the draw in the end.

560 is C3. Period.

A 12hr prime 95 test is not the last place to check for a really defective core....in my experiance in the subject, I have found that gaming is the ultimate way of detecting bad cores, eg a buddy of mine unlocked a 550 to a X4 B50 all was well after a 14hr prime 95 test....ok all good so far, started need for speed shift slight stuttering (strange for a X4 with a gtx 480 but whatever)

Started up crysis and low and behold the gun was jumping all over the place and the sky was all jittery. All in all, after some testing we found that core 3 was the problem, with core 3 disabled, games run smooth as silk. Point being just don't run a stress test program, use your system what you need it for, if it passes that, to me that is the stability test there, but again run a game and make sure there are no signs of a bad core.

Watch out for CPU throttling due to VRM heat (even if the CPU is bone cold). They are a 4+1 unheatsinked, so it's likely to happen and mess with your OC. Most especially if you are using aftermarket tower cooling - not only are VRMs unheatsinked then but not even a smidge of airflow is getting to them to spread the heat

Be careful with the voltage!

EDIT AGH! I really thought I could beat xd_1771 this time!
