I'll make this very fast.

(1) What (2x2gb) DDR2 800 RAM do u guys recommend for OC? best bang for buck? for a P35 + Q6600 build?

(2) Also, what is a good/safe OC number for the RAM and Q6600 on air?

Thanks,

1) Whatever you can find rated at 1.8 or 1.9V.
2) 1333MHz FSB (3GHz core) with DDR2-667 RAM speed should be quite safe on a P35 MB. You likely won't need to OC your RAM with a Q6600, since DDR2-800 RAM is good up to 1600MHz FSB.

1)Crucial Ballistix Tracer RED 4GB (2x2GB) DDR2 PC2-6400C4 800MHz
OCZ 4GB (2x2GB) PC2-6400C4 800MHz ReaperX HPC Enhanced
G.Skill 4GB DDR2 PK PC2-6400C4 (2x2GB) CAS4

Any of these are good. The crucial is probably the better of the lot.

2) 3.0/3.4/3.6Ghz depending on your air cooler. Your RAM will be fine for up to 3.6Ghz @ 1:1 :).

Save your cash unless you expect to get well over 3.6Ghz when overclocking. The crucial ballistix is good for 1000mhz @ C5 timings anyhow.

most all air coolers do well with a quad at 3 GHz. great coolers do ok at 3.2. 3.6 under normal computing will do ok as long as you don't do sustained power user tasks, like multithreaded video encoding or run prime 95.

It's because almost all of the "high clocking" RAM sold these days is just normal lower-quality RAM that needs to be insanely overvolted to reach higher speeds. The higher the voltage needed to reach a certain spec, the lower the quality of the RAM.
The manufacturers just balance how much they have to pay to replace the burned-out modules with how much extra money they make up front by selling the modules as overclocks.

 


I just searched www.pricegrabber.com for the 4gb version of that memory. For some reason I can't find the exact same thing. I did find the 4gb Corsair XMS with 5-5-5-18... It isn't the SLI-EPP version like the first one I posted. Although I'm sure they've gotta make it.

I think the 2GB kit I'm using is the 6400C4, where as that 4GB I just listed is the 6400C5. That's the part # difference.

Here's the lowest price I see for the 2GB kit. Worst case you could pick up 2 pairs?

I went to the Corsair website, and they don't list a 6400C4 in 4GB. They do list their "Dominator" 4GB in a C4 (4-4-4-12 2T), but it doesn't actually show the voltage on their site. TigerDirect had the lowest price but it said they were no longer available. Still that was about $129.74.

4x1GB isn't very good for OCing. 2x2GB is better at OCing, but still worse than 2x1GB.

Truthfully, running 800MHz is more than you'll ever need for the Q6600. Faster ram such as 1066MHz will probably be only slightly faster, but not noticeable. I'd say go for the cheapest DDR2 800MHz ram with timings of 4-4-4-12.
