<<< Need some advice on RDRAM >>>>

[garebo]

I just got hold of the INTEL VC820 mobo that takes rdram. Rdram comes in 3 different flavors, 600, 700,800. Can anyone tell me what difference that will mean. Is it worth buying the 800 variety over 700 or 600? Why?

thank you

Those different flavors are the speed of the RDRAM. Look up what speed your motherboard supports then probably go with the fastest.

 

[daweasel]

The Intel® Desktop Board VC820 supports dynamic memory detection for one or two 2.5V, 168-pin, PC600, PC700, or PC800 RIMM* modules that support ECC or non-ECC. The Intel Desktop Board VC820 supports a single Rambus* memory channel.

Motherboard link for ya

Go with PC800 RDRAM. RDRAM performance is less than stellar with the Pentium III platform, and putting PC600 or PC700 RDRAM on the Vancouver VC820 motherboard is going to reduce performance even further.

remember, you have to put RDRAM in in pairs also...

That depends upon the specific implementation of the RDRAM memory controller. The I820 chipset of which the VC820 is based upon utilizes a single channel DRDRAM memory bus and does need for RDRAM to be installed in pairs.

Are you sure it's not best just to sell this motherboard? Hey, you asked for advice...

 

[garebo]

why do you say that?

 

[richleader]

Considering that it's a dead end upgrade path with slot form processor with behind the curve clock speed (both amd and intel are shipping 1gh+ BUDGET cpus that cost far less to obtain than a classic PIII) that requires an more expensive (though no longer prohibitively so) memory subsystem that delivers inferior to equal performance on the platform: using this motherboard to build a system just doesn't seem prudent. Sell it and use the cash towards other parts.

 

[garebo]

guess I've been told, eh?


The answer to that one is: You asked for it! Yes I did. The truth is always the truth.


thanks
