RDRAM Computer Memory Upgrades

RDRAM or Rambus is easily identified by the silver or sometimes colored exterior heat sheilds. Choosing the correct RDRAM for your machine can be tricky. It comes in different speeds, ECC and non-ECC, and it typically needs to be installed in pairs of two.

Common Questions About RDRAM

Q: Can I install a PC800 RDRAM in my system that already has a PC1066 RDRAM module installed?
A: You can mix speeds in most systems. However the system will run at the lowest speed of RDRAM installed. In this case your system would only run at 800 Mhz.

Q: What are the common motherboards with RDRAM technology?
A: Common motherboards that support RDRAM: Abit SI7, Asus P4T533, Asus P4T533C, Asus P4TE, Epox EP-4T2A3/4/+, Gigabyte GA-81HXP, Intel 850EMV2, Intel 850GB, IWILL P4R533N, IWILL PX400-SN, MSI 850Emax2 Most popular machines that take RDRAM: Dell Dimension 8100/8200/8250, XPS B866, Gateway XL700, Alienware Area-51 with Intel 850E chipset, Falcon NW Mach V with Intel 850E chipset, etc.

Q: Can I install both ECC and non-ECC?
A: Mixing ECC and non-ECC is not recommended. If any of the modules do not support ECC, then the ECC functionality will be disabled and in some cases you may have difficulty booting your machine.
