RAM Question

I have to get more ram.

I have 184 pin RDRAM at the moment running on MSI 850 PRo2 MBrd.

Kingston recomends PC800 ram for this MBrd but I notice that PC2100 is much cheaper at the moment.

I am assuming that I have PC800 RAM installed.  Will it be possible to mix the 2 types?

No, this motherboard only accepts RAMBUS.

Now the solution is to look for the price of a new P4 motherboard that supports DDR + the price of the DDR you want to add on it. Then compare this price to 2 RAMBUS memory modules.

Why 2 ??? Because the memory controller hub of this mbrd is capable of delivering dual memory channels, which allow up to 3.2GB/s of memory bandwidth to the Pentium 4 processor. Then it's better for you to put memory modules by pair.

You typically have to put them in in pairs.  You will need to double check how many slots your motherboard has before you go off to buy new memory. Rdram(RAMBUS) is quite expensive, but that is all you can put into a computer that has rambus slots.  You could probably upgrade to a ddr motherboard and get the extra memory for near the same price as a few rambus sticks.  Check out your options before you decide.  Good luck.

I have no idea about the m/b type or such but naturally you should be able to mix them. The speeds will not match but usually one just slows down to match the other. As rrhunt28 said, you will have to slot them in pairs.

So yes, it can be done.

Good luck.

Hehe Nicky, he can't because DDR and RDR are not based on the same technology, and it will mean that his mobo have 2 chipset (1 for DDR and 1 for RDR) and as far I know there is not yet such a mobo (and I don't think we will see one, one day).

So Julian go to buy an ASUS P4PE and order 2 memory modules at (excellent quality, fast delivery, good prices for brand RAM) and crucial is localized in UK (if I don't make mistake).
