DDR2-800 CAS 4 @ 2.1V vs. CAS 5 @ 1.8V

Is it better to buy ram spec'd at 5-4-4-12 at the standard 1.8V, like this Mushkin http://www.newegg.com/Product/Product.aspx?Item=N82E16820146731

or ram spec'd at CAS 4 at a higher 2.1V like Corsair XMS2 DHX http://www.newegg.com/Product/Product.aspx?Item=N82E16820145194

I'm guessing you could raise the voltage on the Mushkin and get CAS 4. Any thoughts/recommendations? Thanks!

Get the Corsair

If price is taken into consideration, I'd pick the first one, since it's much cheaper for almost the same performance and at lower voltage, which translates to lower temperature. Although it list voltage as only 1.8v, and not, say 1.8-2.2v. Which means if you want to bump up the voltage for overclocking or further tightening timing, it might be a problem.

No idea about brands, I only look at specs.

I know a person running the Mushkin at CL3 and he's perfectly stable. He loves it. He's running 2x1GB modules however, so account for that.

The Mushkin probably has higher or equal headroom, and even if does not, the Corsair would not be worth the extra cash

I would go with the Mushkin as well. I have been very happy thus far with my 4GB kit. You will probably be able to get the ram down to CL4 easily with a small bump in voltage. Good luck getting down to CL3 though. It would probably take a lot of voltage and some luck to get the timings that tight.
