RAM - Lowest latency or Average?

[PSMK]

I'm building my first DAW and ordering from Newegg. Just not certain whether it's beneficial to get the lowest latency or the average one. Both are compatible with the board from ASUS...because I've already checked. I will be loading GPO, SampleTank 2XL and maybe a few more samplers. I believe that these samplers are loaded into RAM, rather than DFD. So, am I better off with the lowest or the average latency? I will not be overclocking, so that is not an issue. Any suggestions?

Motherboard: ASUS "P4C800-E DELUXE" i875P Chipset

Memory #1: Corsair XMS Extreme Memory Speed Series, (Twin Pack) 184 Pin 1GB(512MBx2) DDR PC-3200 - Retail

Model# TWINX1024-3200C2
Item # N82E16820145449
Specifications:
Manufacturer: Corsair
Speed: DDR400(PC3200)
Type: 184 Pin DDR SDRAM
Error Checking: Non-ECC
Registered/Unbuffered: Unbuffered
Cas Latency: 2-3-3-6 T1

OR

Memory #2: CORSAIR XMS Xtreme Memory Speed Series, Xtra-Low Latency 184-Pin 1GB(512MBx2) DDR PC-3200 w/ Heat Spreader, Model TWINX1024-3200XL - Retail


Model# TWINX1024-3200XL
Item # N82E16820145522
Specifications:
Manufacturer: CORSAIR

Type: 184-Pin DDR SDRAM
Error Checking: Non-ECC

Cas Latency: 2-2-2-5

The difference in price is only $50.00, but do I need or would I get the benefit from the lower latency. Any suggestions would be greatly appreciated. Thanks!

It's a good question.

Speedfreak overclockers will always go for lower latency at the expense of bandwidth. So they would recommend a CAS 2 with a 5:4 memory divider over a CAS 2.5 with a 1:1 ratio, ie you're locating the required data faster, at the expense of not being able to move quite as much across the front side bus to the cpu.

In your case, both of those memories are CAS 2. I'm not sure how much effect those other numbers have. But hell, if the lower latencies let you run one more reverb plug-in before maxing out, then it's probably worth the extra $50
