Need Some advice on getting over 355fsb reliably

Ok, I can't figure out what's causing the problem I'm currently having for the life of me.

 

Got my computer up to 355fsb no problems, cpu is a stock volts and NB is at 1.65. Going over 355fsb requires 1.7v nb which is no problem. However at that point I start getting boot issues. If I try and reboot from windows or exit the bios the computer goes into a reboot cycle where it reboots (I hear a subtle click and my cd-rom light starts blinking) right before it would beep and show the post screen.

 

And even when booting from a cold boot it's a roll of the dice if it'll boot right away, restart a few times then boot or just stay in an endless restart loop.

 

I tried upping the cpu vid as I thought perhaps it needed some more juice, no dice there. Tried the same with the NB and still nothing. So I'm quite stumped as to what it is, I have read Raju's guide and have most things set as they were suggested to be set in there.

 

I know my NB is getting pretty toasty at 60+c at load but I don't think that would be causing a problem with booting?

 

Thanks for any help you guys can give :)

Ok, update on me being a putz and not checking all the settings. I had to do a clear cmos and my PPM (No idea what it is but everyone says to turn it off) was enabled and pcie was set to 100.

 

Just to test, I disabled PPM and no dice. Turned PCIe back to 101 and it booted fine.

Yeah, I need a HR-05 SLI bad... That Ultra-120 makes it so I wouldn't be able to fit any other NB coolers on the board.

 

Quite sure on the CPU volts. It's sitting at 2.56 taking anything I can throw at it and having no problems.

 

Got the Ultra-120 cause I thought I'd need to up the voltage and now I'm wishing I had got a NB cooler and used my Zalman 7000 or 9500. Oh well, the Ultra-120 is really nice though :D I do wonder if I have it seated correctly cause it does get to 43-44 under Orthos load :confused:

 

As for the snow, that wasn't bad at all. And seeing how it's the most snow we've gotten all winter I'm not about to complain.

 

 

EDIT:: Grrrr... Guess that was a fluke getting out of the bios cause it went into it's reboot cycle after rebooting from windows. And is sitting in one again after cold booting it.

 

Later Update Edit:: It seems that in fact the CPU did want more voltage. Wound up giving it +25mV and it boots reliably. Guess it was a good thing to get the monster heatsink. Strange that it would bench and run Orthos with no problems yet have problems booting. :confused:

Yea I am having trouble with getting a high FSB as well.

I am stuck on 375Mhz...

I have disabled all the unused ports etc. And all the CPU 'enhancment' stuff.

 

I should prob make my own thread ;)

 

Good luck.
