P4A 2.3 533Mhz and mobo

I'm leaving AMD and going for a P4 2.3 533Mhz CPU.
Does anyone run one of these and how far can it be overclocked?
Also thinkin of what MB to get. Seen the Asus P4S533 which can take the DDR333 ram. I've never run with the SiS chipset but from what I've read it seems ok?

Comments?

Cheers subz

You should get a motherboard that has Intel chips on it. Even a 645dxSis mb with oc pc3200ram is 20% slower than an i845 g with pc 2700. Somtimes you get cheated when you buy cheap.

If you're going to get P4B then you need to get RDRAM. Check pricewatch, RDRAM and DDR are pretty much the same when it come to price but not performance, especially if you are going to OC. As far as mobo makers. I would go Intel or Asus, definitely the 850E chipset. Asustek's P4T533C(which I currently own)or Intel's 850E MVDL or something screwy like that. Both boards have everything but firewire and RAID onboard (that included USB 2.0 and some unwantedextras like o/b video and sound). But apparently have gotten the hint andare planning new mobos with firewire and RAID o/b and w/o the video or sound o/b. Sorry but I am not able to produce a time frame for you.

Hope this helps!

HULK SMASH!!!

If you are planning to overclock your best to stick with the Intel I845E chipset.

The BD7-II and the IT7 both accept the newest DDR and overclock extreamly well.

The P4S533 is a good board but not for the overclocker, its for the tight budget with performance.

With the IT7 you would break 3Ghz but im not sure how far the stock HSF will go above 2.8Ghz good airflow or a aftermarket copper HSF and your golden.

Here is <A HREF="http://fugger.netfirms.com/3122.jpg" target="_new">my P4 Northwood B @ 3122Ghz</A> with a Swiftech MCX478 HSF and generic case/psu.

My CPU is a 2.4B, motherboard is a IT7, corsair XMS DDR PC3200.

Here is a <A HREF="http://service.madonion.com/compare?pcm=401997" target="_new">Page 1 PCmark2002 score</A> without too much effort.

As you can tell, I use what I recommend and know first hand on this subject.

You are limited to what your mind can perceive.

Roger all that, so to summerize:

The SiS 645DX chipset runs PC2700 and is fast plus can run PC3200.
The intel 845G chipset can runs PC2100 plus can run PC2700.

Both have good reviews.

Are both chipsets reliable? and is there any advantage of one vs the other?

Seems the SiS chipset boards are cheaper but are they any worse in standard vs the intel chipset boards made by the same company.

Thanx for all the help I'm getting

The G in I845G denotes onboard video, ICH4 versions support 533FSB so be carefull because some I845G are 400FSB only.

The I845E has 533FSB

If you can afford the few dollars for I845E it is well worth it.

There are no compatability issues that I know of for the above chipsets other than AGP2.0 video cards.

The disadvantage of the SiS chipset is higher speed overclocking with stability. Like I said before this is not a "choice" overclocking chipset like the I845E.

Roger that...This is what I've ordered.

Asus P4B533-V 845G Chipset.
P4 2.3 533
512 Samsung PC2700 ram

The 845G is the chipset to go for not the 845E (read toms article) also here is a great forum thread re the OC of this board. 3 pages of good stuff.

Cheers for the help

Not a bad choice, but I see your missing some key information. ICH4 chipet = I845E and I845G, the G denotes the onboard video, other than that these are the same chipsets. Did you need onboard video?

Now the IT7 is slightly different, obvious change is legacy free, Second is the HPT374.

Agreed, the P4S533 won't go over 160MHz FSB without losing the extra mem-ratios. Surprisingly however, it IS stable at high clock speeds with PCI devices, even though it doesn't lock the PCI/AGP bus (as least it doesn't "officially" ). I'd recommend the P4S533 for the Pentium 4A and the BD7(II) or IT7 for the Pentium 4B if you're considering a DDR platform

Yep and one advantage is price! SiS powered mobos are useally much cheaper and running fast and stable with 140 -160 FSB is not all that bad IMO Sure for the extreme overclocker who is looking for higher then say 160 FSB then go with the Intel Chipset.

Too bad they don't make anything under the 2.26GHz. I would love one with a lower multiplier so I can raise the FSB to astronomical speeds!
