p4t533 memory - ECC/NON ECC/4/8?????????

[dbarton]

Was in the middle of placing an order and got lost.

I am ordering 256m memory for a p4t533.

Googlegear has many kinds of RDRAM: ECC, non ECC, 8 device, 16 device, 40NS, RAMBUS, ORIGINAL RAMBUS. Too many!

1. Which one of these do I want??

2. Samsung ok, or is there a better choice? (ASUS seems to suggest Samsung 1066 on Googlegear MB area, but they dont sell Samsung in 1066 size - just Kingston)

2b. Kingston a good choice??

3. Better to get 128(x2) Samsung 1066, or 256(x2) of 800 memory? Running win 98 now with 128m total. If I get 800 I'll get 512m - If I get 1066 can only afford 256m.

Help!!

Order the PC1066 memory. Make sure you buy them in pairs(two 256 MB or two 128 MB pc1066 RIMMS). Get ECC memory if you need error correcting code. This memory raises your memory bandwidth to 4.2 GB/sec from 3.2 GB/sec. If you can't afford this memory, you can go with the PC800 memory as long as it is rated at 40 ns speed. The older 45 ns speed PC800 RIMMS will not work on this motherboard. Kingston uses Samsung material. So, it should be as good as Samsung unless you really want to be sure and want Samsung memory, then buy Samsung memory.

I agree with vsekh, get the 1066 if you can afford it. I would recomend 2x256mb sticks for a total of 512. 256 is not much unless you are only running office and such, many applications and games want more. Also, check out this Thread for some issues with that MB and fast memory. The end result is you need to manually set the RDRAM multipier in BIOS to 4x or upgrade to a beta bios. Some people were lucky and it worked without these steps, but many have had some trouble.

I'd very much like to see that thread, but it's for subscribers only..

Can anyone summarize or is it worth paying to join?

My bad, I just became a subscriber and I forgot to link to it from the normal area. Try this Link instead.

Much appreciated!

I am going to set things up on Mionday, btu have no idea what settings go to what..

If there's a quick setup list for the bios, I'm all ears.

Under the advanced tab, there is an entry called something like RDRAM multipler. It defaults to auto, change it to 4x if you are using PC1066 and not overclocking. If you have trouble with that try 3x instead. Auto has problems with PC1066 though, so don't leave it set to auto.

I assume I can set a hardware jumper in order to boot up so I can change this in the bios.

(No 800 memory here..)

You must mean P4T533-C.

P4T533 uses RIMM4200 modules and isn't in the channel yet. But soon.

I'd use 32ns PC1066 modules. 27ns if you can find 'em, but probably you'll have to settle for 32ns.

Well, no not so far as I know. But like I said, some boot with no problem, some boot really slow, and even I was able to get into bios 2 tries out of 20 or so, so you should either have no problem, or with persistance be able to get into bios and fix it.
