:hello: Hi, I have a few questions concerning DDR2 RAM.

1) Does the number of sticks you have make a difference? I ask because I saw a 8gb kit with 4 sticks that was much cheaper than one with 2 sticks, and the same for 4gb of ddr2. Does this mean anything, like more cards=worse performance? Should I buy an 8GB kit or buy sticks individually?

2) Is there any performance difference between DDR2-800 and the higher ones like 1066?

3) What exactly are timings? For example, I see RAM with 5-4-4-18, and one with 6-6-6-19. What do these mean, and what should I shoot for?

Thanks! :D

1. Generally with out a good motherboard it may be hard to run 4 DIMMs.

 

2. In benchmarks yes, in real world no.

 

3. http://www.hardwaresecrets.com/article/26

#1 over 4gb ram you need 64bit operating system.
#2 the motherboard has to support or limits the amount of ram
#3 in most cases stick with DDR2-800. For best results the fewer sticks the better like 2 x 2gb sticks vs. 4 x 1gb sticks. Also for best results choose ram that defaults at 1.8v and has a lower Column Address Strobe (CAS)
like 4-4-4-12

1-usually kits with less sticks perform/overclock better and are more stable
2-no, not worth it unless you overclock... like a crackhead
3-for ddr2 800, shoot for 4-4-4-12 or something really similar... or less maybe
ddr2 1066 5-5-5-15... those are normals

I see, the mobo is 780i btw.

Well, since you guys say DDR2-1066/DDR2-1200 doesent give better performance than DDR2-800 (which I find weird, why would it cost more?), hows this kit? http://www.newegg.com/Product/Prod [...] 6820227291 It has 4 sticks, but its very cheap, which is why I like it.

But money isnt a huge problem. Any 8GB DDR2 you guys can recommend?

Whoa, the lower the timings the better?

Then why does RAM with higher timings cost more?

By the way, this site http://www.theinquirer.net/en/inqu [...] ice-timing also shows that DDR2-1066 gets more fps than DDR2-800... so I guess it does apply to real world..

A whole 1 fps isn't worth the extra cash for DDR2-1066 over 800. Better off doing what the guys in the review you posted did, and oerclock the 800 RAM, that is... if 1 fps is that massively important.

If not, DDR2-800 is perfectly adequate. Personally, I like to underclock my RAM to run at a 1:1 ratio with my CPU's FSB (my 800 is underclocked to 667 at the moment).

Alright, well can you recommend some good 8GB DDR2-800 or up sticks then? Those OCZ 8GB for $150 seems way too good to be true... so can you recommend any really good ones?

I'm using 4 x 2GB sticks of OCZ Platinum RAM. It does the job nicely in my opinion :)
