Thanks

Well, I too have a similar question. What does RAM latency timing mean. Lower is better or higher is better ?

Lower is better, I think CAS 8 should be more then fine and shouldnt be that big of a diffrence from CAS 7. Also I really wanted a 1.5v set all the ones with CAS7 are 1.6v sets.

Just want some pro opinion

That Ram is fine. 8-8-8-24 CL8 isn't the best but it will be more than enough. Personally I would grab a 2x2gb kit if you are just going to be gaming.

For just gaming surfing and overclocking no need for anything more powerful than this RAM,

If you want to benchmark or other, you might want to splurge on the better RAM but really that kit is all you need.

Timings are how many clock cycles the RAM has to wait before it can execute the same operation again. Lower (aka tighter) is better.

At 1000Mhz a clock cycle is 1ns. DDR3-2000 runs at 1000MHz, and if CAS = 10 then it has to wait 10ns.

At 800Mhz a clock cycle is 1.25ns. DDR3-1600 runs at 800MHz, and if CAS = 8 then it has to wait 10ns.

All these different setups have to wait the same amount of time.

DDR3-2000 CAS10
DDR3-1800 CAS9
DDR3-1600 CAS8
DDR3-1400 CAS7
DDR3-1200 CAS6

DDR2-1000 CAS5
DDR2-800 CAS4


In general, higher speeds will give better performance b/c you don't always have to wait depending on the operation, but don't sacrifice timings too much to get there. And if you can't reach the speeds you want then drop down, and tighten timings to get to almost the same end result.

Is a 1.6V kit going to be any problem with sandy bridge?

Some people say I really should get 1.5v ones?

Also my local vendor pretty much only has the gskill 2x4 sets

Feel free to recommend me one if the one I posted aint good or so

1.6v is fine

for everyday use, ur not going to notice any difference between different timings/speeds

get 1333mhz 9-9-9 and call it a day, spend the savings elsewhere

I run G.Skills 2x2GB 1600MHz with Cas7 and 1.6v, they run fine on SB.

If you can use 8GB then the ones recommended will be fine but honestly a 2x2GB kit will do you fine more then likely.

All DDR3 should have a 1.5v SPD setting. You can run it a little slower or looser on the timings and drop the voltage down if you're worried.

Look at the SPD tab of CPU-Z.
