Help on RAM please. Building 2 systems on P5B-Dlx/WiFi.

Hell everyone.

Thanks for taking your time to read my question.

I am planning on building 2 systems, both with P5B-Deluxe/Wifi boards, but one with E6600 and the other with E6400.
What would be the better choice for RAM for the systems above?

1) Crucial Ballistix (BL2KIT12864AA804) DDR2 800Mhz PC2 6400 2GB Kit (1GB x 2) 4-4-4-12
2) OCZ (OCZ2P800R22GK) DDR2 PC2-6400 800MHz Platinum XTC Revision 2 2GB (2x1024MB) Dual Channel Kit 4-4-4-15
3) Corsair XMS2 TWIN2X2048-6400 Matched Pairs 2GB Kit (2x1GB) PC6400 DDR2-800 CL 5-5-5-12 240-pin Dual Channel Memory
4) Mushkin EM2-6400 DDR2-800 2x1GB EM Series CAS 5-5-5-12 (996527 (2x1024MB))
5) Patriot Extreme Performance DDR2 2GB PC2-6400 Eased Latency DIMM Kit (PDC22G6400ELK)

I heard good things about g.skill rams as well, but I could not find a retailer in my area (Toronto).

Thanks you.

p.s The rams above are all in the same price range after mail-in rebates(about CAD $100)

Thanks alot for your advice. So E6420 is better than both E6400 and E6600 (when overclocked)?

As for the link to newegg, thanks for looking up for the link, but Newegg does not ship to Canada

If you can not get the G Skill ram in Canada. I would go with your #2 choice.

Since they also use the Micron D9 memory chip modules.

I have the same (less the Wi-Fi part) mobo as you and use 4*1GB OCZ DDR2 ram, same mentionned here. I have them running at 833mhz and 2.15V (well below 2.2V covered by warrenty) at 4-4-4-15. They had the best price when I got my computer. Even with 4GB, they are as stable as can be, no complain at all.

One thing tough. When I went to get the last 2GB, I was tempted by the Corsair stick. The guy where I got them didn't want to sell me the Corsair stick, or more exactly told me not to do so. They had (at that time) slightly better price thenm the OCZ for the same timing. He explained me that they had numerous RMA on Corsair sticks. With C2D system, most of the time only one of 2 stick would be detected, leaving you with only 1GB instead of 2. I actually had to go get my OCZ stick somewhere elses since they were B/O on them that week. That makes me believe that wasn't only to get more money out of my pockets. Check this out, since I never heard of it prior to that day, and not since either.

Don't buy from eBay, thats usually a bad idea.

Don't buy the OCZ.

eBay is where people sell used products. There is a much higher chance that the product will not work as well as a new one.

OCZ makes either bad RAM, or good RAM for much higher than it should cost.

Since G.Skill make great RAM for a much lower price than it should, I suggest buying the G.Skill from an online store.
