Using a P4 with 400mHz FSB on a 533 mHz M/B

[Guest]

Archived from groups: alt.comp.hardware.overclocking (More info?)

hi all

I currently own a P4 1.7 Northwood 512 kb cache, with 512 SDR Ram, the
M/B has a FSB of 400mHz.

I 'd like to upgrade my system by getting a M/B that will support DDR
Ram, but i'd like to keep my P4 1.7 for now. If I buy a 533mHz or 800
mHz M/B will my processor be compatible? Might it be possible to
overclock it using the 533 setting to 2.26 gig (ie 133mHz x 17 = 2.26
instead of 100 mHz x 17 = 1.7 mHz) or have I got the wrong end of the
stick?

thanks for looking

Gaz

My P4 1.8 400 runs flawlessly at 533 for 2.4 with stock heat sink and fan.

Never heard of a Northwood 1.7, so it's likely a 1.75V 256kb cache version
limited to ~2.0GHz (Williamette?). There's nothing of the sort on Intel's
s-spec page for P4's - all 1.7's are 256kb, 0.18um (none are 512kb,
0.13um)...

Unless Intel snuck out some undocumented processor that can't be a
Northwood as the slowest (documented) Northwood is 2 gig.

yep, your both right, I double checked and it's only got 256bk of L2 cache.

so I'm stuck with 2 gHz at best?

were the 1.6A and 1.8A designated as something other than Northwoods, by
Intel?

Well, no, I wouldn't say you're necessarily 'stuck' with 2 gig. A look at
the overclockers database indicates that 2.2 might be a reasonable target
and there's even one posted at 2.5, supposedly with the stock Intel cooler,
but you can't always trust what someone claims. The average was about 2.1.

Well, sad to say, what you have is not a 'Northwood' Pentium 4 (the one
with the 512 KByte L2 cache), but a 'Williamette' Pentium 4 with a 256
Kbyte L2 cache and a 0.18 feature size rather than the 0.13 feature size of
the 'Northwood'. It is not worth spending money trying to upgrade a system
and and still use that CPU, especially if you intend to overclock ( a
'Willamette' Pentium 4 is VERY limited in top clock speed, and the smaller
L2 cache is a real bottle neck.)

You are in the position of needing to replace the memory, CPU, AND
motherboard to get back on the step by step upgrade path. Since ANY
reasonable upgrade is going to require new memory and a new motherboard,
that is certainly the place to start, but don't let the compatibility
requirements of your present CPU limit your future path. A 'Prescott' 2.4
GHz Pentium 4 currently has the lowest price among Pentium 4 CPU's (a
'Northwood' 2.4 GHz and a 'Prescott' 2.8 GHz CPU are about the same price, ~
$175 US [both with 800 MHz FSB.]) You could expect to spend at least $175
US for an overclocking friendly motherboard and 512 MBytes of generic
PC3200 DDRAM.

I have a 1.8 Williamette CPU which I run at 1.98 (4x110) and it is fine and
stable. I have tried to go above 2ghz but I get an instant crash (using
Easytune). Something thats been bothering me is my manual says the board is
a 400FSB but it has FSB settings all the way up to 133. Does this mean I can
run a 533FSB CPU? The max multiplyer is 24 and the board is a GA-8ITXE with
an i850 chipset.
Any feedback greatly appreciated.

WRONG. Williamettes came in both pinouts.

Depends on the motherboard. If your RDRAM is PC800, it will not overclock
by 33%, so you would have to be able to use the async memory setting (5:4
ratio for FSB:memoryclock.) In fact, memory speed might be your limit even
with a .200/1.8 = 11.1% increase for PC800.

Thanks for the info. The ram is PC800, i'll play it safe and just keep
looking out for a 2.4 with 400FSB. Oh and the CPU is 478 pins.

A Pentium 4 2.4 GHz with a 400 MHz FSB is $180 US at
http://www.zipzoomfly.com .
Yeah, I know it is a flaky name, but they were once called 'googlegear', and
I think google.com complained. I've bought memory, motherboards, CPU's, and
hard drives from them and had good experiences.

Then you can get THAT Pentium 4 2.4 above 3 GHz using the 3:4 ratio and
PC800 overclocked only 12.5% even at 3.2 GHz, so the memory speed of your
current PC800 will likely not limit your CPU speed.

I have a Pentium 4 1.6A running at 2.4 GHz using using PC800 and that
method. Basically the FSB is running at 4/3 X 1.125 X 100 MHz X 4 = 600
MHz, while memory is running at the equivalent of an FSB speed of 450 MHz,
just a 12.5% overclock.

If you are using win98 classic, you are limited to speeds less than 2.2 GHz.
At that speed it will refuse to load a driver due to a divide-by-zero error.

Only if you don't get the patch for it. There is a patch for that just as
there was for the win95 350MHz divide by zero problem.

Great info Phil, thanks. I've saved it for future reference when I do
finally pick up one of these critters. I'd ordered a 2.4 400FSB CPU from
PCBuyers.co.uk for £70 yesterday but they called this morning and said
they're out of stock. $180 US is tempting but out of reach atm at over
£100. I'll keep a look out for a 2nd hand one.

Incidentally, do you think that a Celeron 2.4 will out pace my 1.8
Williamette running at 1.98 and how are they for overclocking? They are nice
and cheap at about £50 but will it give any significant boost?

Cheers again,
Spizz

True, there is a patch but getting it requires a call to MS and may involve
a trouble-call fee. I heard the patch only works for two weeks anyway so I
did not mention it.

That Celeron and the rest of its family has only a 128 Kbyte L2 cache, and
thus has a severe limition on its performance. You'd be much wiser to look
for a 'pulled' Pentium 4 2.4 GHz with a 400 MHz FSB. The price and
availablity of a new 2.4/400 is likely because they are no longer made (my
guess.)

You can find it on download sites, although not easily.

Sounds like an old wives tale.

What do you mean bt "Pulled"? I'm back in the OC game and assuming a
2.4/400 is a good candidate?
