Rdram Or Ddr-sdram

[bambang]

I am looking to upgrade my mobos and processor. Should i get i a mainboard that uses RDRAM or DDR-SDRAM. I tried to google for some info on this ram thing but i can't understand what they are saying.

I am currently ASUS P4TM with 386MB (64MB*2 + 128MB*2) of RDRAM (PC800)

I dun mind spending some money on DDR-SDRAM if it's good.

Thanks!

DDR is better.

i also have rdram pc 800, and from what i can gather, the speed difference is negligible. so MY opinion would be to save a few bucks and buy DDR, cuz you can get more memory for the money of RDRAM. especially since they have DDR pc3200, which is what my brother has , and its wicked fast, even on a 1.8ghz P4. again, just my opinion :flowers:

Wat kind of DDR-SDRAM? PC 2100, 2700 or 3200

Thanks for your fast reply.

Am i right to say the the higher the PC XXXX the faster it is?

Yes, that is correct. I would reccomend PC 3200.

Thanks for all the advice. :P

is rdram not made by rambus which is now bust??

RDRAM is outdated and no longer used on new chipsets, so it would be a bad idea to get a RDRAM-based motherboard because that severely limits your upgrade options.

DDR SDRAM is much cheaper and continues to be developed, so it would be a good choice. You should select the speed which matches the Front Side Bus (FSB) frequency of your CPU.

[bigdawgfoxx]

Yeah get the speed that matches your FSB, or you can get higher speeds and run them at the speed of your FSB, if you ever want to overclock.

Intel P4 3.2G GHZ 533 MHZ*/800MHZ*

How to see this FSB frequency thing from the example above?

The closest thing would be to use 400MHz DDR RAM.

The 800MHz is actually a quad-pumped 200MHz bus, so the dual-pumped 400MHz DDR would be the best match.


edit: just noticed that 533 was also mentioned; that&#39;s a quad-pumped 133MHz bus, so DDR266 would be the best choice as detailed above.

[bigdawgfoxx]

400Mhz ram is PC3200 BTW.

Thanks guys&#33;&#33;&#33;

early on, P4s pretty much required RDRAM in order to perform acceptably because the conventional SDRAM and DDR SDRAM standards of the time (2001?) weren&#39;t quite up to snuff...

but DDR SDRAM does just as well nowadays as RDRAM ever did.
