Guest rodchar Posted August 5, 2007 Posted August 5, 2007 hey all, i'm wanting to install more memory in my desktop. From what i see in my bios i see the memory speed is 533 MHz. And I went to a memory configurator on the web for my system and it says the memory speed available for my pc is 667 MHz will this really work for my pc? thanks, rodchar

The speed ratings can be deceptive (in many ways.) If you buy RAM that is 'faster' than what you need - given your motherboard manuals say it supports it - the faster memory will just 'clock down' to the speed of the slowest memory in the system. The speed rating is the 'tested okay at' speed. Use http://www.crucial.com/ to find what memory you need to buy, what configuration it must be in, etc. They guarantee their selections. -- Shenan Stanley MS-MVP -- How To Ask Questions The Smart Way http://www.catb.org/~esr/faqs/smart-questions.html

However, be aware of a gotcha. Many motherboards although designed for the faster memory speeds are frequently not actually tested, because the memory didn't exist at the time of release. Occasionally, fitting the specified fast memory leads to mysterious and frequent crashes, freezing and so on. If this happens then manually configure the motherboard for the next lower speed (consult the motherboard handbook for how to do this).
