RAM questions

[Maxxarcade]

I just bought a 1GB stick of PC2700 on Ebay, to put in my DVR server. It is rated at CAS 3, but could it possibly run at 2.5 on a PC2100 board? I know some PC133 could be run at CAS 2 on PC100 boards, but not sure if it works the same for DDR.

Also, how long will it take for a gold plated DIMM to mess up a tin plated socket? I've never worried about it, but some people insist that it will corrode.

I have 384MB of ram in my Linux based DVR server, but TOP reports that there is only about 3MB free at any given time, with about 100MB of swap used. Hopefully more ram will improve performance, because it has gone up to a load level of 6.5 at times

Re: RAM questions

Most of the DDR I've ran different than SPD has been a crap shoot. Just like SDRAM, who made the chips and how the contoller was programmed makes a huge difference in what settings can be run over/under stock.

Re: RAM questions

Will the SPD still work properly when ran at lower than specified speed, or should I manually set everything in the BIOS?

I also forgot to check if the AK31 board I have is a new enough version to support 1GB sticks... if it's not, I guess I'll have to swap ram with my KT400 based board.

Re: RAM questions

When set to manual, most of the boards I have will still maintain what SPD said untill you change each individual setting. So, yea, you can keep stock values on aything you don't change.

Auto by SPD does not have anything to do with fsb AFAIK.
