Asus P4B533-E Memory ?

[LawrenceTalbot]

The Specs for this Mobo states it supports PC2100 and PC1600 which I have no interest in. Would I be able to use PC3000 or PC3200 instead and get the proper performance from those chips??? Also how would this setup compare to either RDRAM at 800 or 1066??? Thanks

There really isn't much point in getting anything faster than PC2100 on an 845 board. Maybe PC2700 would be OK for a little extra OC headroom. If you want to use faster DDR memory, you'll need a SIS 645DX board.

There are plenty of articles with benchmarks out there comparing various memory types on a P4, starting with Anandtech.

To answer your question, yes, you would be able to use PC3000 or 3200 in that board. I have PC3000 (Corsair) in my P4B266, and there is no problem. You will get slightly better performance if you go with the higher end ram, this is due to the cas latencies. The real reason that you would want ram that fast would be if you were heavily overclocking, or using the 3:4 cpu/ram ratio. IE: CPU 100 RAM 133 or CPU 133, RAM 177mhz (PC3000 or so).
An RDRAM setup will beat a pc1600-pc3200 setup; for now. RDRAM is much faster, but at this point, there really is no need to spend the extra money for the RDRAM. DDR ram technology and motherboards are getting better, and are within an arms reach of RDRAM boards.
This board will be a great board, and many people on this forum will be upgrading to it when it comes down in price (me included).

Of course you can USE PC3200, but you're going to be running it at PC2100 speed. It's virtually impossible to push a 845's fsb high enough to need PC3000, let alone 3200.

And why would that be?

Not true. Yiu need to buy the right 845 board and set it up properly.

I'm running an EPOX 4BDA2+ board and a P4 1.6A @ 150 FSB = 2.4 GHz. Using the 4:3 mem ratio, I run PC3200 (DDR400).

According to THIS the P4B533 fsb will go to 200
So I believe that PC3200 would be a good thing to buy.

To get full use of PC3200 memory you need to run a 150mhz FSB and not every Northwood will overclock that high. If your CPU can overclock that high than its memory scores will beat a rig running PC800 RDRAM and probably tie or beat a rig running PC1066 RDRAM but if the board running RDRAM is overclocked to 150mhz its memory scores will beat your DDR board at 150mhz.

1) How do we know yet what this board is capable of...

2) Can agp/pci speeds be kept in spec with aggressive OC ?...

3) I'm deciding this weekend what rig I'm getting... between the Asus P4B533-E and the Rdram P4T533E, with the P4 1.8a cpu...

4) Going crazy.....Geez... what do you think, guys?

Actually RDRAM is cheaper than PC3000/3200
