RAM Memory Module Upgrade

Question

I have a DELL Dimension 8200 with MS-XP service pack 2.  I installed two DELL RIMM 256 ECC 8C 40 modules in the 'dummy-CRIMM' slots.  The increased memory is recognized by setup but the system fails to boot up.  I replaced CRIMM cards and all is well.  I reinstalled memory modules and the problem persists.  I have not tried replacing the two 128 cards with the two 256 cards.  Should I?  DELL Tech support is telling me to return cards but I fear they will send me the same card type card and I will still have the same problem.  Time is running out on a project which requires the additional RAM memory.  Help anyone.  I mistakenly posted this earlier in the non-technical  forum.

It reads that the RDRAM modules you purchased are not compatible to your system and need to be returned.

Here are the memory specifications for the Dimension 8200.

Dimension_8200: (sold before May-6-2002) Chipset: Intel 850. System motherboard has a 400Mhz FSB. Has 4 memory sockets. Each socket has a maximum capacity of 512MB. Minimum system RAM is 128 MB. Maximum system RAM is 2GB. Uses RDRAM-Rambus PC800Mhz. Memory must have a 45ns rating. Uses ECC or NON-ECC memory.

Dimension_8200: (sold after May-6-2002) Chipset: Intel 850E. System motherboard has a 533Mhz FSB. Has 4 memory sockets. Each socket has a maximum capacity of 512MB. Minimum system RAM is 128 MB. Maximum system RAM is 2GB. Uses RDRAM-Rambus PC800Mhz. Memory must have a 40ns rating. You cannot use older 45ns RDRAM on this system. Uses ECC or NON-ECC memory.

Thanks for your feedback.  My DELL Dimension 8200 was purchased in September 2001.  Your reply states that the memory cards must have a 45ns rating.  I do not know what the 45ns rating means or how to check it on the card sent.  The cards DELL sent me has ELPIDA EBR25EC8ABFD-8C, 0510SXC0093, 256MB/8d ECC, 800-40, G100 S110 typed on the label.  Does the 800-40 mean it has a 40ns rating?  If it does then it appears DELL sent me the wrong cards.   I tried replacing the 128MB cards in the 1 & 2 slots with the upgrade 256MB cards but no luck.    Please reply.

Please reply.

"Must" is incorrect, the info is from before 40ns memory existed. 45 or faster works fine, you have faster.

Dell sent you the wrong memory, as they often do for a Dimension 8200. Return it, get a refund, and order the proper memory via the Samsung part numbers on my site or found all over the forum.

I originally tried to install DELL memory cards but they seemed to be incompatible.  I could not boot.  I have sense purchased a pair of 256mb/8 memory modules from Samsung:  Model #MR16R1628EGO CM8 800-40 01.  I removed the 128mb cards and replaced them with the upgraded memory.  I am sure they were seated properly.  I am still unable to boot in XP.  Are the cards I purchased the correct cards?  Any suggestions.
