Good afternoon everyone. I need some memory advice. According to the AMD web site, the following memory listed below is compatible with all AM2 processors. I need clarification as to which memory would be best for a 3800+ or 4200+ AM2 processor, as noted below. The Motherboard this processor and memory will be used on is the Asus M2N-E. I am looking for 2GB (1GB x 2) of memory and don't want to drop more than $300 or so on it, give or take a few.
For the first PC2 3200 (DDR2-400)
For the second PC2 4200 (DDR2-533)
Appreciate the input. The actual figures all come out to 400 for all X2 processors when you do the math on a calculator. There are .25 and .50 and .75 figures to deal with for some or the speeds. It appears that you are rounding the multiplier. If I get a 3800 model with PC2 3200 memory (2GB) and then 10 months from now, I want to upgrade to a 5000 or above, would that require I replace the memory with PC2 4200 or above? I keep seeing system configurations with PC2 4200 and PC2 6400 and other memory speeds with various X2 models. I assume they are OC'ing? I have no need to OC. I just don't want to get memory for a slower processor that isn't useable on a faster model in the future. That sounds like a very pricey upgrade path being forced by AMD. Thanks!
For a 5000 you are going to need DDR2-533 PC-4200. There may even be faster processors by the time you upgrade.
Just redo the calculations with a speed of 2600. 2600/6=433.
Don't get confused because the speed of the FSB is 200 in all cases.
Yes, the divisor must be rounded down.
