Issues in games after unlocking AMD Phenom X2 555? - Page 3

post #21 of 41
Giving more voltage on an unlocked/125W TDP processor may overload both the motherboard mosfets and the power supply. At the moment I would not really recommend it at all.

Very well, I will try setting it manually. I am not overclocking at all rightnow, and how do I find out what is the FSB set as?

UPDATE: Tried setting Vcore at 1.45v, same issues persist. At this point, I'm guessing either is the unlocked cores aren't that stable, or something to do with the RAM.

Ok, a big update, tried many different setups, but I'm puzzled as hell right now..

I tried the following:
- Underclock the processor to 2.0 GHz, with VCore at 1.4V, 4 cores enabled, same issues persist.
I then returned the settings to normal(normal clocking, VCore at 1.4V)
- I tried setting 3 cores in the BIOS, same issues persist.
- I tried setting 1 core(disabled all others), same issues persist?!
- I tried setting 2 cores, and it still gives me the same problems.
While there were variations in how prominent the glitches were, they were still there no matter how many cores I had enabled. Apparently as long as my processor is read as an AMD Phenom II X4 B55, and as long as Unleashing mode and ACC is on, I get the issues. So what now? is it a motherboard issue?

well i can tell you this: on an 890fxe, my 555 will give me problems if i have core unlock enabled, even if i do not press f4 or f5 to unlock cores (that's how it works on that board). simply having it on, even with no cores unlocked, will cause issues (if your 2 cores are bad). your problem may very well be that your 2 cores are not stable. that's the first thing that it could be. second thing is that it is not a core issue but a bios issue since you said that the problems persist even in other situations. what i recommend at this point in time is for you to reset the bios. look for the 3-pin CMOS reset. you need a jumper or a paper clip to reset the CMOS.

Yeah, your processor's behaviour does seem similar to mine. But can the 2 dormant cores affect the others even if they are turned off? And I will try to reset the BIOS as per your advice.

Right now there is something wrong, I just want to know if it is the motherboard or the RAM so that I can replace them or send them back for replacements before its too late (warranty periods in Egypt are not that long unfortunately :/ )

Just got another MEMORY_MANAGEMENT BSOD, with my processor as a dual-core. This means the fault lies in what? Motherboard or memory?

Anyone knows what these BSODs are caused by?

You never said whether you tried increasing the CPU-NB voltage or not. What is it at right now?

Have you run Memtest on those ram sticks?

No, I have not tinkered with the CPU-NB voltage at all. Would increasing it solve this or increase stability when at default clock? Right now, the NB Speed is at the default of 2000 MHz, and the NB multiplier is at 10x.

And I ran the Memory test tool that is available in the boot menu of Windows 7, no errors found. Although I read it is not that trustworthy?

Looks like it might be the memory corrupting some things then. Run some rounds of memtest86+! Memory_Management can and does usually mean failed memory.
