EDIT: Hopefully you get this. Make sure CPU Voltage is at least 1.4 V in BIOS. Don't set it to auto.

Maybe that would get you your boot.
Yea those are supposed to be the stock factory OC'ed settings on the RAM. I have to have my CPU/NB @ 1.4v or my system won't even run Prime95 blend with "EVERYTHING @ STOCK". Sucks that I have a CPU/NBv that high to run prime95 with a 3.2ghz stock clock..

Oh I didn't know you were having that problem. That sounds very odd; I run mine overclocked just fine with 1.25 V. Maybe it's a RAM thing. Does it work at stock with CPU/NB on auto? If not, you may have a faulty IMC on your chip.

Anyhow, if you're sure about that then don't touch CPU/NB Voltage and just try loosening the timings again. I'm not sure that 20 on the end will help but if it does then we've taken a big step.

What exactly is IMC? I can run prime95 sometimes with everything on auto, but most of the time it fails (would freeze 1-10 seconds after starting blend test). Once I boosted my CPU/NB voltage I never got that problem again. And Its stable.

IMC stands for Integrated memory controller. The phenom chips have the memory controller in the NB chip, which is why you can run DDR2 or DDR3 on them. It is dependent on the motherboard, not the chip.

it only causes issues when you push the NB chip or push the ram speeds. because the NB contains the IMC and does data for the memory and cpu. so it is a big part of data flow.

I was having problems before pushing ram speeds. Ran memtest for 12 hours and figured it wasnt my RAM.

That may be it..

but then why when I bumped my CPU/NB voltage to 1.4 It stopped failing? Is it a bad memory controller?

The memory controller is on the CPU die. No company has put the memory controller on the Northbridge chip since Intel's LGA 775 platform. DDR2 support is dependent on the mobo's support for AM2/AM2+/AM3 with DDR2/DDR3 DIMM slots.

Note "integrated memory controller" in the ad.

Maybe. That or your RAM or anything in between. If everything isn't stable and at stock, then there may be bad hardware.

Yea, at stock it would freeze during some games and even web browsing and surely while running prime. I figured it couldn've a been hardware issue but couldn't figure out what. First I thought it was my PSU, Then Memory, then Mobo... but Now I think its the CPU..

Does higher CPU/NB voltage help out a faulty IMC? Cause When I bumped it up it stopped giving me issues.
