Replacement part for Asus P4T533-C

My problem is that my P4T533-C Asus motherboard has died after 5 years of service. I believe that the existing P4 CPU and the Rambus memory are virtually unusable in any system today. So, I need a specification for a motherboard, CPU and RAM (1 or 2 GB) that will work with my existing remaining good hardware, like the case and drives etc.

I need a top quality (5 card slots like this one had, built-in network and sound etc),  reasonably priced setup that will last another 4-5 years, like this one has, with an occasional part upgrade. I would like to keep the Grandmars video card if possible, but if AGP is now gone, I will accept having to replace it as well.

Current system:

Motherboard: P4T533-C (broken)
CPU: Intel Pentium4 533 FSB 3.06 GHz (Not sure)
RAM: 4 x Samsung 256 MB PC1066 RDRAM (fine)
Video Card: Grandmars x1300 256MB AGP8x (fine)
Hard Drives: 2 x M axtor Diamondmax Plus 9 160GB ATA / 133 (fine)
SCSI Card: Adaptec AHA-2940U2 FAST / ULTRA-SE (fine)
Case: Lian-Li PC-60 ATX  mid-tower (fine)
Power Supply: Enermax 350W Whisper Power Supply (20 pin ATX12V, I believe) (fine)
CPU Cooling: Vantec Aeroflow VP4-C7040 (fine)

I would really appreciate some expert advice on this. Any questions, dont hesitate to ask&

Boards with the VIA PT880  chipset would be able to handle your change over except for the RAM.

Thank you for your fast response, Sparkmaker...

Any other suggestions for either a more readily available motherboard that can use the original P4 processor and new generation RAM, OR a newer generation board, CPU, RAM combo that will fit the case and be able to use most of the accessories...?

I don't see the Asroc board for sale anywhere except eBay (used, one would be lucky to get a new one anywhere, it seems). If you know of an outlet that has them new that would really help...

Thanks!

I recently saw some new Intel 850 chipset boards for sale, but don't remember where. That would be a nearly exact replacement. Will take a look and see if I can dig one up.

Boy, they must have lost that shipment in the warehouse for a couple of years.

Maybe because the 850 chipset died a deserved early death along with RDRAM :-) Actually, it's not unusual to find new, older Intel motherboards. Guess they keep a significant spares inventory.

Guys, responses greatly appreciated! Before I buy one of those boards I have 2 questions:

1. Will my 1066 memory work in those slots - they are PC800 -  (and just drop down to the slower speed)?
2. Will my x8 AGP card work in that x4 AGP slot and also just step down in speed?

The answers to those questions is "yes" then I will close the quewstion out and be very happy to apportion the points! :-)

Regards!

1-The PC800 is Rdram (RAMBUS)which will work with the boards posted by willcomp that have the 850i chipset. They will not work with the PT880 chipset boards. RDram has a totally different structure and architecture that DDR ram(DOUBLE DATA RATE ram). See the attached pic. The top module is DDR the bottom is RDram. Notice the difference in the notches along the bottom. RDram will only fit in a RDram memory slot.

2. The video card should do 4x and clock down, since it worked in the old board which only had a 4x AGP slot, check the documentation for the card from the manufacturer.

Spark... OK, that answers #2 above, but I don't think I explained my question in #1 above, properly.

 I fully understand that the Rambus won't fit in a DDR system.... my question was meant to ask as follows:  I am using PC1066 Rambus memory, while the board suggested (the Intel board that uses Rambus) is rated for PC800 Rambus memory; will my existing PC1066 memory still work in the PC800 slots of the new mobo?

Thanks!

Yes, it is supposed to work. It wil throttle down to match bus speed.

At least one of the used boards has a 1066 memory bus.

That is dependant on the motherboard revision as to the backwards compatibility of PC1066 on an 850i motherboard.
The first one that willcomp has posted, states -->'PC1066 support is only available on D850EMVR desktop boards (AA#'s C18369-603 & C18361-602 or later)"
from the Intel support page for the D850EMV2  (lacks the L designation as it was probably made for an OEM like HP,Dell or Gateway.)
http://support.intel.com/support/motherboards/desktop/d850emv2/sb/cs-010572.htm

Crucial states both PC1066 and PC800 for the D850EMV2 but the revision number from Intel would be the way to go. Intel chipsets of that age were very particular as to the ram they accepted.

The second board willcomp has posted (D850MV) only accepts PC600 and PC800 with no menton of PC1066.

Of course the ones I posted don't support it at all (don't want to sound picky as to willcomps posted boards)

The third board (from Ascendtech) supports PC1066 RDRAM according to their description. I'd trust Ascendtech -- have bought parts from them before and they are reputable.

MarkCommented:
@ willcomp--> the intel site doesn't mention PC1066 for the D850MV as there were two flavors of the chipset 850 and 850E, with the 850E being able to run the higher speed RDram.
BUT, that is a Gateway board and certainly may have the capability.
They were designated as
Lexington- supports PC600-800 http://support.gateway.com/s/MOTHERBD/Shared/Upgrade/2515762ui.shtml
Lexington2- supports PC600-800 http://support.gateway.com/s/MOTHERBD/INTEL/2516016/2516016fp.shtml
Lexington3-supports PC800 or PC1066 http://support.gateway.com/s/MOTHERBD/INTEL/2517882/2517882sp37.shtml

So you have to be careful and ask the vendor for the specific  part number on the board.
Here are the Lexington3 part numbers
2517882, 2517883, 2517885, 2517887, 2517888, 2517889, 2517890, 2518001, 2518002, 2518003,
2518738, 2519060, 2519077, 2519082, 2519088, 2519098, 2519148, 2520532, 2520533, 2520682,
2520683

It looks like the board may or may not support the memory that I have... just as an aside, what do you think of this deal, going along the original lines of the Asrock suggestion: http://sfbay.craigslist.org/nby/sys/547766380.html Would this be a reasonable buy?

I am really sick of the issues with a Rambus system... everythings a problem!

I would just keep my current graphics card and processor as spares, which I don't mind doing.

Guys, you have been very helpful... I am just going to go with the Intel board. From everything I have read the 1066-32P memory will run in it. Its $79 so if there is a problem its not going to be the end of the world. I really appreciate your help and will split the points equally... Regards!
