If you have that CPU and did an overclock on it, please let us know the results. This chip overclocks very well I hear. 2.4-2.5Ghz are being reached. Pretty decent price if it indeed can do that overclock consistently. What is a 2.5Ghz P4 equivalent in terms of the AMD XP chip?

Plucky

Over at Aceshardware, they did some test on various CPUs.
From the results I'd say the 2.2 Northwood is an equivalent of an XP2000+.
The Northwood is faster in some test and vice versa.

Myself I have a 1.6A and Giga GA-SRX SIS635 chipset.

Rock solid at 147fsb = 2.34. Vcore bumped up from 1.5 to 1.70
Funny thing is I can't even get to boot up at 148fsb at all but it will run prime95 all day long on 147fsb.
I suspect the problem is the MB or the Power supply.

I have another setup with a 1.6A and a Asus p266-C.
I actually bought this for someone else but I got to play with it first.
It was solid at 150fsb = 2.4 at 1.65 vcore.

Too bad I don't have both right now or I could see which chip or MB is better.

I didn't do anything special, just upped the FSB and Vcore.
Generic powersupply and Crucial rams.

Very very quiet setups compare to my AMDs.

I received my P4 1.6A and Asus P4B266-C in the mail yesterday. Hopefully I can get the system put together this weekend and post a few numbers.

P4 1.6A @ 2112 (132 FSB)
Set the FSB to 132 in order to use the 3:4 memory timing for the RAM.
Stock Intel Fan and Heatsink
CPU temp = 34 C
Vcore = 1.5 volts
Asus P4B266-C
256 MB Crucial PC2100
GeForce 4 Ti 4400 with latest Nvidia reference drivers (28.32)

3dMark 2001SE = 9961 @ 2.11 GHz

Are there any reviews comparing overclocked 1.6@2.4 vs regular 2.4 and other cpus? I am curious how much the 150MHz bus helps the P4. I like my current AMD XP setup, it is easily the fastest system in the house but it makes more noise than the other three computers combined.

Blah! bunch of traitors in here...

hard ocp has an article on their frontpage about good mobos for oc the 1.6a. they like the msi 645 board, msi 845d and the epox board. i was looking at the msi web site and it looks like they will have the new iteration of the sis 645 chipset in may with built in usb 2,0 etc. i almost pulled the trigger today on a combo (cause the 1.6a;s were 133 shipped at new egg) but decided i'd wait a little bit longer and check the new 645 boards.

LOL i find that link amusing MAC... You see that XP2000+ 1.66 Gig chip up at the top of most of the benchmarks hahaha...

if you extrapolate a little bit, the lowly 1.6a @133 fsb should clean the XP200's clock

If ya can get it up past 2.4 Gig it will in most benchmarks.. Needs 800Mhz more to do it i'll pass My poor ole 1700+ will clean the 2.4 clock in most benchmarks... But its running at 1.7 gig so

msi 645 ultra/1.6a runs sandra, etc. @ 150 fsb, not stable yet in 3dmark 2k1, runs fine at 133 fsb no prob

Asus P4B266C and 1.6A

2,208 at 1.5 volts. Cooled with an alpha 8942 with a Sunon 40 cfm fan.

CPU idles around 28C.


As of the other day it is now

2,400 at 1.6 volts. Same cooling. Really no difference in temperature behavior.

My rig:

Asus P4S533
P4 1.6a 2400Mhz@1.6v
(2) Sticks 256mb Corsair XMS2700 2/2/2/5/auto
ThermalRight AX-478

I thought my Celeron 1.0a 1500Mhz@1.775v was fast, but my new rig owns it
