Hello,
I'm using OEM computers (Core2 quad) with non-ECC PC RAM for server.
I have Kingston's HyperX RAM on them. They're actually for PCs. HyperX RAM has heat sinks on them.
Currently used ones are 4 GB DDR3 1333 MHz HyperX CL7.
4 GB DDR3 1600 mhz HyperX CL9 is almost half price of that RAM. It's faster but cas latancy is CL9.
Also there's a normal (not HyperX, not have heatsink) RAM that's 1333 mhz and CL9. And almost same price with the second.
I'm using the server for MySQL + Apache. There's about 300 MySQL queries per second and the database is about 20 GB in size.
OS is FreeBSD 8.2
I'm not have problem with current RAM, however I'm developing new applications and I want to scale the servers. I'm not sure which RAM I should go with. I can use 1600 MHz RAM with overclock and so that I can only use one per channel. This is half of the slots. 1333 MHz CL9 RAM has no heatsink but it's more cheaper.
I don't know much about cas latency's effect on servers.
Do you think that my current RAM is worth the price? If I go with overclocked 1600 MHz or 1333 MHz CL9 RAM, will they decrease the performance of the server?
The last question, does ECC RAM affect performance? Do they worth the price?
I wonder your opinions.
Thanks.
