1333 vs 1600 at 7-7-7 vs 9-9-9

[xiangjiao]

Hey,
Which would be better and could you explain a little?:
1333 mhz with 7-7-7 timing cas latency 7
or
1600 mhz with 9-9-9 timing cas latency 9?

Both will be similarly priced and under 1.6v running on asus p6x58d-e + i7 930 and ati 5870. Will be used for solidworks and gaming.

edit: this will be 3x2gb
editedit: these are the ram in question

Please try to answer in general then with these two specifically. Thanks

Hi.

1333 with CL7 is better in this case.

Basically not all depends of the RAM speed the perfect match is low CL and high speed. The CL means the response times that takes the RAM to delivery the requested data to the CPU or memory controller between more high more time to response.

Those kits are good but take a look of this G.Skill PI 1600 with the same CL7 but 1600 and a fewer price.

looks good. think i'll get that one then.
do you think there will be a noticeable difference between the 1600 cas 7 and the 1600 cas 9? does it warrant the $30 upgrade?

Yeah, 1600 CL7 is like 2000 CL9 and that PI series is a very good OC RAM.
