So, would the heatsink retention bracket then be above the ct-479? On stock setup, ct-479 rests on the bracket. How does this affect the 4-pin power connector...would that have to be removed? Pics...

Like fugger said, boot to bootable floppy w/ flash program and BIOS also on the floppy. Assuming you are flashing to BIOS 21, at the command prompt:

a:\afudos p4ced21.rom
It's just that easy. ...

Yes, going to 133 mhz FSB in BIOS will give you 1:1 or 4:5 dividers.

Definitely go with the 533 mhz FSB P-M. They hit higher bus speeds, whereas 400 mhz are limited to ~160 (yes, guys around here have done better, but on average, they are limited).

I tired RMClock, and got x6 multi, but with no "real" results (only "software" results...). I belive TAM or NewBeetle (whichever of them had this same setup) had a lowered multi for 21s superpi, and...

If you look at a picture of the adapter, you will see. ;) There are two jumpers and a FDD power connector on the board. Those jumpers dictate FSB.

You will have to first flash to 1021 without the adapter installed (i.e. w/ a northwood or prescott installed). I think I remember seeing that fugger and possibly one or two others, ran into...

Hmm...I don't know. The change would take effect, once written through crystal cpuid, for me. I got the impression that it wasn't a physical change, but rather a "software" change only, but it...

Ah, well you see, there it is there...I told you I wasn't savvy...*previous post edited* :slapass:<---me

Props goes to zawanao, at EOCF, who showed me the ways. On the 'Function' pull-down menu, click on 'MSR Editor'. Read address 0x0000199. The setting for EAX will be 0x0000xxyy, with xx being hex...

Not on the P4C800. I think the P4P800se is the only one that allow BIOS vcore adjustment.

There was mention above, in Kristos' post about this board: "from what I read on madshrimps, vegeta's board is already dead and the results he got before it blew weren't good, he suspects no locks...

Well, I'm seeing guys in the Superpi WR thread with adjusted multis. One has a P4P and one has a P4C. I personally have tried adjusting multi through CrystalCPUID, but regardless of what it's set...

^To add to the arguement, w/ P4C800-e deluxe and ct-479, overclocking is extremely limited w/ stock cooler. The stock cooler of the ct-479, altho it is 3x bigger than the one that comes with DFI...

^Ordered mine from www.atacom.com last week, and received it three days ago. I don't know if any of them ship internationally, but have you tried any of the above linked e-tailers?

Hey Kamel, awesome guide. I did these mods, and they work flawlessly. :toast: Firstly, any recommendations on what vAGP should be set to? Secondly, does vAGP also control vNB (if you know)? ...

It could be the RAM timings or voltage, but the RAM itself isn't even approaching rated speeds. :confused: Like these guys said, set timings to 3-4-4-8 for now, and set vdimm to 2.8v. What's your...

:with: You have to populate the correct slots, as well: 1-3, 2-4, or 1-2-3-4. :thumbsup:

Yeah, that's true....well hey, he got a massively OC'ing 2.8 there! :p

Well, my theory is that, in a rush to get these chips on the market, Intel either inadvertently side-stepped part of the manufacturing process, or did it purposefully. I was looking for this...

.....so Intel would have us believe.

Well, if he's gotta go 5:4 at 272, then some PC4400 or PC4500 would allow for higher 1:1. It was a hypothetical question, not necessarily a suggestion. ;)

This is a normal occurrence w/ pre-Prescott BIOS'es on both the IC7 (BIOS 18 or older) and the P4C800 (BIOS 1015 and older). The older BIOS'es can't ID the processor correctly, and it apparently...
