But its only one stick of RAM.. should I try to change its position?

I meant a heatsink for the mosfets. Since unlocking instantly adds 40-50W to the power usage, I highly doubt the HEC is enough. HEC power supplies, especially lower end ones, are not of good quality.

I'm sorry, but you'll have to bear with me I don't even know what a mosfet is, and a quick Google search reveals they are the little transistors/capacitors around the processor socket? Well, I don't think my motherboard has heatsinks for those, although there is a heatsink right below the processor socket?

And regarding the processor, well, the one I have has shielded cables and looks a bit less dodgy than the older HEC 300W one I had In any case, someone suggested using OCCT to check any variation on the 12V, and in my case, the variation was constantly between 12.4V and 12.6V, would that be OK?

OP could you fill in your system specs in userCP up the top of the page and look in the list on the left side of the screen then click on edit system.

Also it just sounds like the core was shut off for a good reason in this case, it's not a guaranteed thing to have stable cores after the unlock.

dude. 1.2volts? give it more voltage. i have a 555 too. i'm at 1.51volts @ 3.9ghz on my weak 555. my good ones do 4.2ghz at 1.46volts. 1.2v? i'm not saying that will solve your problems, but it's a good start. i would give it at least 1.40volts.

yup. did hours of prime on one of my 555s, no errors or crashing. then within 15 mins of Starcraft 2, blue screen. prime95 will not catch all instability errors. the best test is using the processor in normal use. if you got games, run them.

Now that I have read the 1.2v, me thinks his friend needs to hit the books again.

serious. that's the very first thing that came to mind. i am shocked that an overclocking forum did not say anything about the 1.2volts. that is very, very low voltage for an unlocked 555... very first red flag.

Added my details as requested.

And while I did mention the system did run stable at 1.2V, I changed the setting to Auto for all my tests, which sets it at 1.4V, with no difference in results at all.

While it is probably a shaky core or something, I was hopeful it was something I could solve by tweaking around in the BIOS settings, I read people suggest changing CPU-NB?
I just want to know if it has nothing to do with RAM, since it does look kinda dodgy, and those few MEMORY_MANAGEMENT BSODs have me wondering..

Thanks again for your time!

you need to set the vcore on manual. 1.4volts is what my motherboard sets it at with just TWO cores, at STOCK speed. 1.4 volts for an unlocked 555 may work, but there's a solid chance it's too low as well. if you are OCed, then it is definitely on the low side.


Are you overclocked at all? What do you have FSB at? Give us more info.
