4GB should be enough for most programming, however I would get 8GB for extra headroom. Ram is dirt cheap, so you won't be out of pocket.

yeah.. dirt cheap. i can get Mushkin Red Line DDR3-1866Mhz 2x4GB Cas9 for 56 euro (about 70 dolars) or 4x2GB DDR3-1600Mhz Cas7 for 50 euro (about 60 dolars). witch of these 2 do you recommend is better? CPU will be PII x2 555 oc @ 3.7-3.8GHz and MB is Gigabyte GA-970A-UD3 will upgrade on amd piledriver no matter what.

Either of those RAM kits will work fine. There is almost no system performance gain from OC'ing DDR3 RAM unless you have an AMD APU.

The default RAM speed on the PII 555 is 1333 MHz. so either RAM kit should be able to OC a bit if you desire. The latency timing of DDR3 also makes little difference as the real time becomes less as the frequency increases.

Pick the RAM kit you like! thumb.gif

am.. i know that memory controler is set to 1333Mhz, same as Intel SB but i didnt ask that... let me put it this way, Cas7 need to do less cikles before doing anything then Cas9 but this Cas9 hase more speed 1866Mhz compared to the 1600Mhz so in Mhz vs Cas letacy, whats more important? 7-8-7 vs 9-10-9

Neither. The real time of one cycle changes as the frequency changes. Thus as frequncy increases real time may stay the same or close even though it requires more cycles for a command to execute. Many tests have been run and some applications respond a little to CAS and some to frequency, but overall system performance change is almost unnoticable.

With older, slower DDR or DDR2 RAM, latencies made a bigger performance difference because the real time per cycle was longer than with DDR3 RAM. This is not the case with the higher frequencies of DDR3 RAM. That's why there is almost no system performance gain unless you can double the frequency.
