To do 5 passes took around 13 hours. Dennis

Just based on when the units were released and what the memory/motherboard standards were at the time.

I don't think DDR2 and DDR3 are interchangeable. For one, there is a notch for alignment that won't lineup for the other style.

Out of curiosity... why 8? Running a big workload, like VM, on it?

I bought a similar Patriot 8GB back a few weeks ago at Frys. $125, works fine.

Why does the Pro/Ultra 6 use DDR2, while the lower spec' unit like the Ultra 2+ uses DDR3?

I'll try a some Patriot though, it's worth the gamble.

Bah, the Patriot DDR3 was a no go. :(

Wish the websites would use correct images for the RAM being sold. Twice now I've bought the DDR3 which is pictured with 4 chips per side, but upon delivery I see immediately they actually have 8 per side. Complete waste of time and money.
