Memory - SDRAM or not?

I have a Fujitsu-Siemens Euroline 1.8MHzIntel P4, with a Microstar MS-6391 motherboard and i845 chipset. Currently has 256Mb PC133 DIMM - is this the same as SDRAM? I want to upgrade to 512Mb, but there are two offerings - one that says SDRAM and the other that just says 'PC133 DIMM'.

I downloaded teh .pdf brochure from Fujitsu-Siemens, but that doesn't even say the motherboard accepts Pentium 4, llet alone what type of memory can be used for upgrade!

Can anyone help?

 

ps. I am obviously also dyslexic & illiterate!

 

your board will take pc100 or pc133 SDRAM. make sure you get pc133 because its the best the board will take.

 

Actually, you most certainly want PC-133, PC-100 will not work if you're running the FSB at the proper speed in that system! In addition, SDRAM and PC-133 are the same thing, they're both SDRAM.

Are you sure you don't have DDR memory in that system? I have a i845 chipset system, and it uses PC-2100 DDR memory. Does your memory module actually have PC-133 stamped on it?

 

i think I'll have to open her up and have a look - according to the online manual, it shouldn't even be able to support an Intel Pentium 4! I bought it from 'BuyANicePC' in Nov. 2001 & their 'tech support' is non-existent. I spoke to a chap at Fujitsu, gave him the SN off the back & he told me what the motherboard & chipset were. Very frustrating!

I agree that Belarc Advisor is a useful tool at times, but it's not always that informative about what memory in installed. Here's what it says about my 512mb of PC2100 DDR memory.

Slot 'A0' has 512 MB
Slot 'A2' is Empty
