I wanted to know if the OCZ2P800R21G memory will work in the Gigabyte GA-EP45-UD3R motherboard.
I have 4 one gig. sticks I want to use with Windows 7 and Vista.

Thanks for the info. GhislainG.

I have one more question.
I am looking at 8gb of g.skill f2-8500cl5d-4gbpk to go along with the Gigabyte GA-EP45-UD3R and a Q6600.
Wanted to know how it has been working for people.
I have never used g.skill before and like everyone, don't want to play with different ram in a new build.
All info would be helpful good and bad.

Thanks a ton!

I use 8 GB of G.Skill PI Black DDR2-800 at 4-4-4-12 and 1.8V on a GA-EP45-UD3P as well as a P5Q Deluxe. Getting 8 GB of 1066 MHz RAM stable is more difficult. If it's not stable, you can always lower the speed, increase voltage or loosen the timings a bit.

Thanks again GhislainG.

I will have my new mb and cpu here by wednesday!
Already have the 4 one gig. ocz mem. from current pc but thinking about going from 800 to 1066.
I have also been looking at the Kingston HyperX KHX8500D2T1K2/4G.
Have always liked Kingston. Never let me down and made in USA.

Have 8G of G.Skill F2-8500CL5D 1066 @ 1080 (450x2.4B) & 2.05V on a DS5 (same family) stable as a table... Corsair & Kingston seem to often give GB MOBOs indigestion!

I have been reading to many reviews about ram the last few days.
So far, most ram needs a tweak or two.
I'm not afraid to do some tweaking, just don't want to make a 40 hour job out of it.
Have been wondering what the major dif, is between 1066 and 800 because I am looking at the Kingston Hyper X.
Eather one of these....KHX6400D2T1K2/2G or KHX8500D2T1K2/4G.
And Newegg has always had the best prices since I have been building PCs.
There is about $15 - $20 dif. between the two.
So if I can get about the same performance from 800, thats what I will look for.
Looking to buy in the next week or two so any input will be great!

Unless you are overclocking beyond a FSB speed of 400, you only need 800mhz RAM. This is true for all LGA 775 boards. There is very little to no difference in actual performance.

Yes I plan to oc my q6600 to about 3.2 or so.

1066 MHz modules are certified to work at that speed (though they don't always work reliably, particularly when installing 4 modules). 800 MHz modules might overclock to 1066 if you loosen the timings and increase the voltage (like the manufacturers do). Unless you run benchmarks, you'll never be able to tell the difference.

Your Q6600 runs at 266mhz x9. As 400x9=3.6Ghz, you can see that 800mhz RAM would be plenty for that processor.

RAM has to run a double the FSB (at least). So let's say you had the FSB at 350.

That would mean your RAM would have to run at least at 700mhz.

So I would pay more for 1066 with no performance increse?
with an oc. of 3.2, what speed memory should I use?
Will be using Gigabyte GA-EP45-UD3R, WD 640 x 2, Q6600 oc to around 3.2 with what ever memory I narrow it down to.

Sorry, I'm tired and just trying to stay awake. To be clear:

With an overclock of 3.2Ghz on a Q6600, you only need 800Mhz RAM
