Is it okay to use RDRAM PC 800 45 for 40

[mossimo817]

I'm not to keen on the whole computer thing but I hope I can explain this correctly.

I have a Gateway 700S (2002) with an Intel Petnitum 4, 2260 MHz, 133 MHz external bus, Bios- Intel Corp. MV85010A 15.0049.P07.2024171416
RDRAM PC 800 40 256MB.

I bought a 1 GB RDRAM but did not realize it was for PC800-45. I tried to install it but it says I need the 40. Is there anyway I can still use this? I bought it on Ebay and can't return it. Any suggestions would be helpful...please ...thanks!! !

I'm no expert on Rambus but shouldn't you be able to modify the Rambus multiplier ? AFAIK it should be 4x for 533 MHz PC-1066 Rambus, you should use 3x to match the 400 MHz PC-800.

I'm not sure what you mean...can you explain what you just said...? Thanks!

Rambus clock frequenc is generated by FSB and multiplier. Your FSB is 133 MHz and typical Rambus multiplier is 4x, that's why PC-1066 RDRAM (533 MHz) is required. By lowering the multiplier it should be possible to use slower PC-800 RAM running at 400 MHz.

Please try to find such a multiplier in your Bios or check your documentation, maybe there's a different setting in your Bios like asynchronous memory speed.
