Since, people kept telling me to stay with 800 and not go 1066...which RAM should I get?

Desktop Memory (x) > Capacity : 4GB (2 x 2GB) (x) > Speed : DDR2 800 (PC2 6400) (x) (1-49 of 49 Results)

RAM LIST: http://www.newegg.com/Product/Prod [...] (PC2+6400)

Leaning toward: http://www.newegg.com/Product/Prod [...] 6820227267
OCZ Reaper HPC Edition 4GB (2 x 2GB) - $80
Cas Latency 4
Timing 4-4-4-15
Voltage 2.1V

(1) Also, I think I will OC the Q6600 to 3.0-3.2...and I won't need to OC the ram...right? I just want a safe OC on air...I hear some do 3.2-3.6....but I rather be safe...3.0 is a good number or 3.2?

(2) And is there a point in buying 1066 RAM is I don't plan to OC CPU that much? I mean...is there any other advantage to having a 1066 vs 800 RAM besides the ability to OC CPU more?

(3) I am a little worried that I won't get pci-e 2.0...but hopefully I won't need it anytime soon..

Any 800 ddr2 should do, ideally one that oc to 1066. I know this one does, because I use it:

I'm sure there are other cheaper 800 models that also run at 1066 though. Read the newegg user reviews for each one and see if they reach 1066.

Q6600 at 3.6ghz is perfectly safe. It's the most common oc for g0 stepping of that cpu. Your p35 will have trouble going beyond 3.6, but the cpu don't go much beyond 3.6 anyway, so since their bottlenecks are around the same point, it's the best possible value, assuming you don't upgrade cpu.

Dagger is right. If I were you I'd check the manufacturer's Qualified Vendor List (QVL) and Newegg's reviews for both the mobo you have and the RAM you're considering. Again, skip the DDR2 1066 and just get some good hightly overclockable DDR2 800.

thanks guys...but is there a point in OCing the RAM to 1066 if I do not plan to run the Q6600 passed 3.2? (im don't like to OC much). Is there any other benefit with RAM 1066 w/ Q6600 @ 3.2 vs RAM 800 w/ Q6600 @ 3.2? would i see a performance increase?

Well to get a 3.6 GHz OC. You will want 450 x 8 = 3600 MHz. So your ram would need to get overclocked a little yes. 100MHz to be precise. After you OC your ram to 900 MHz, I would leave it at that and tighten the ram timings.

i c....sooo....400x8 = 3.2, which is max CPU OC w/ RAM 800....and....533x8 = 4.26, which is max OC with RAM 1066.....and.....450x8 = 3.6, which is max OC with RAM 900 (100 OC on DDR 800). got it - thanks.

yeah I think ill stick with not OCing the DDR2 800 RAM for now..and just OC the Q6600 to 3.2...maybe in the future OC the ram to 1066 and push CPU to 3.6.

heat! heat! heat!
