Sorry to pop in on your thread, but I figured at least 4 people in here would know the answer to my question :)
I just added a Chilly1 single stage to my P4 550 and hit 5GHz (unstable, but I got my screenshot/verification ;). I have not gone over 1.60Vc because I am not really sure what is "safe" on phase. It's a D0 step with default Vc of 1.40V (1.38V?). If anyone can shed some light, I would appreciate it!
Thanks
Your safe to 1.7Vc if your SS is up to it :D , I wanna see screenies of 5.5Ghz :p:Quote:

Something odd that I noticed: when I set it to 1.65Vc, it wouldn't boot...just stayed black screen and I had to do a hard restart, but when I lowered the MCH voltage from where it had been, it booted at 1.65Vc no problem. So I broke out a spare PSU (Enermax 550W) I had and moved all my fans from the mobo headers to the 2nd PSU and now it boots at 1.65Vc with all other voltages maxed in BIOS too. Think I have a PSU issue with the OCZ 600W? What are you people running 5GHz+ on P4s using for a power supply...single or dual 12V rail PSUs? My old Enermax is a single 12V with 36A on one rail compared to the OCZ with 20A/18A 12V rails.
There's also something fishy with SetFSB though. Memory-wise, it locks up a lot sooner than using FSB in BIOS. If I test mem well below max OC levels, using BIOS to set FSB it will run DDR1032 no problem, but using SetFSB to raise clocks, it craps out at like DDR960. Anyone else notice anything like that?
Thanks again
Can someone post a link about a working setfsb?
The first link that Stilt gave is not working, I mean gives error and does not function.
Can anyone here tell me in which pins can I read the real vdimm on the memory slots?
thankx
i hope you mean this:

TheStilt,
may i ask you what DRAM Write recovery time you used to hit these amazing bandwidth scores?
Cheers
I used Twr = 2.Quote:

so basically,
CL4 2-2-2 and Twr=2 ?
Yes,Quote:

I have also used few refresh and hyperPath tweaks ;)

I already tried, and I saw that some pins don't have any voltage at all, while others have 3.3v...and others the same voltage that I read on the measuring point that is in the picture that ou posted...But, just for double check, I would like to know in which "pin does vdimm entrer in the memory stick".
Thankx
