please help me to choose memory. I want to use GIGABYTE GA-EP35-DS3P board and according to the specifications: it has a fsb of 1600 (O.C.)/1333/1066 requiring DDR2 1200 (O.C.)/1066 memory. Which memory can I use? I want to use 4GB(2x2GB). In other forum some members have suggested using ddr2 800 but the minimum fsb of the motherboard is 1066. How do I do this it if it's possible. I am a newbie so should I stay with 1066 as I don't know about overclocking.

Thanks in advance.

1. I have this board without the DES. It works perfectly with 800MHz DDR2 (a GEIL Black Dragon kit). Corsair/Geil/Kingston/Mushkin are a safe bet but just about any quality 800MHz DDR2 kit will work.

2. FSB is QuadPumped meaning 266MHz physical frequency equals a 1066MHz data rate and 333MHz frequency equals 1333MHz data rate.

3. Intel's memory controller uses a physical frequency x 2 (for dual data rate, DDR) and x 2 (for two channels) layout. So dual channel 800MHz DDR gives you a data rate of 1600MHz.

4. You only need 1066MHz DDR2 if you intend to overclock beyond 400MHz FSB. Since you are a "newbie" you likely shouldn't try that until you gain some experience.

They only tested those modules. It's dated anyway. Nobody buys 2x512MB modules today. Corsair 2x2GB modules would be my pick.
Some links :

As far as Intel overclocking guides go, graysky's thread ( )in the Overclocking forum is as good as it gets IMO. The last Intel CPU I had before my Q6600 was a P200MMX. It helped me alot. I never really searched for other guides.

^Even better as it's for a GA-P35-DS3x board. I completely forgot about that one.

rs - those specs for the MB are not the minimums -- you can always run memory or the MB at a slower speed than its rating. You've chosen an excellent MB. As a rough rule, take the FSB of your Intel CPU and divide that by 2 to get the speed you should run your RAM at. For example, if your CPU is running at a 1333MHz FSB, set your memory bus to run at DDR2-667 speed.
Finally, stay away from OCZ RAM, as they tend to overclock their RAM further than other manufacturers, and this leads to compatibility problems.
