So my B55 (555 unlocked to quad) is doing 4ghz stable with stock voltage (1.4v). It can easily do 4.1ghz with a little voltage bump, though I can't seem to get 4.2 to even last past 30mins-1hr in Prime95 or LinX, though I've only gone up to 1.48v. I can even get the NB to 3000mhz with only 1.4v for my CPU-NB voltage. I really love these C3 chips.
Here's a validation with 4.3ghz, though it's not Prime95 or LinX stable:

then when i do a push/pull with the H50 i should be golden hopefully i get my CPUtemp to 30 or below on idle then i might crank up the volts to 1.46ish
Last night i got to the windows load screen with 3996Mhz with the voltage at 1.42 but then BSOD
Cpu-NB i think i had it 1.32v? (cant remeber) Im seriously thinking my Ram is holding me back i've gotten to 3.9Ghz with one stick before - but wasnt stable at all.
i think my HT Freq is at aroudn teh 2550Mhz mark - it booted extremly quickly but BSOD 2 seconds into windows.
what should i alter im sure i can crak 4Ghz with this setup (maybe more if i change the ram - looking at Mushkins redbacks but i kinda wanna keep the colour scheme too haha.
Glad those fans are doing great for you!
Though for increasing your vcore, you shouldn't worry so much about your idle temps, but instead, you should be looking at your load temps (hopefully 55C or below).
For a C2, you'll be looking at 1.5-1.55v for 4ghz and even then it might not even be stable. Also, try to overclock one thing at a time, so just OC the cpu and see how high you can get that, then start with your NB freq, then finally RAM speed and/or timings.
Try to keep the HT Link freq. as close to 2000mhz as possible, since anywhere past 2200mhz will actually make you lose performance. I usually try to keep it at 1900-2100mhz, which ever is closer to 2000mhz.

Works great for me, I get temps around 30-34C depending on if my window is open and maybe jumps a few C when in load.

make sure to get new thermal pads also for your VRMs
It's not necessary, but it would help much better than the stock ones.

Actually the only important thing is that it's a FAT32 format. I have mine set as DOS-bootable and it has gpu BIOS files in there and other stuff, but I was still able to use M-Flash in the BIOS menu to get up to the 1.G BIOS.Edited by Kokin - 12/16/10 at 9:25pm
