Hi,i am looking to upgrade a few bits and peices of my pc and one of those components is memory but one thing that have never understood is the different timings. Some are something like:
7-7-7-20
7-8-7-20
8-8-8-24
7-7-7-24
9-9-9-24
7-9-7-21

What should i be looking for regarding these timings and why? or is there not alot of difference.

Many Thanks

Timings themselves don't mean too much, and the 'speed' is a greater function of the RAM's ICs and CAS tightness:

7-7-7-20
7-8-7-20
8-8-8-24
7-7-7-24
9-9-9-24
7-9-7-21

So ALL things being the same, the fastest is as follows:
7-7-7-20
7-7-7-24
8-8-8-24
9-9-9-24
{the other 2 could will be slower in comparison to the same CAS counterparts, and only a benchmark like Super-PI can determine order.

Then you'll need to take into account cooling {fins}.

Thanks malmental for going through that and i think that you may have cleared somthing up for me unintentionally,i have just run 3DMark 06 and listed in my specs it had my ram down as 400Mhz, i was thinking wtf,my ram is actually 800Mhz,so thats right then,phew lol.So basically the smaller the numbers the faster the ram will be.
Thanks again.

Cheers malmental,much appriciated,the stuff you learn on here is brilliant.The way i approach my ne xt build will be different to how i have done it in the past thanks to the people on this site.
Cheers.
