memory timing or frequency?

hi,
im trying to upgrade my compaq v3030ca notebook memory from 1gb to 2gb. i have two options
1- pc4200(recommended by hp)533mhz latency 4-4-4-12 OR
2- pc5300 667mhz latency 5-5-5-15

now, i do a lot of multitasking, keeping that in mind, i wanted to know which one i should go for, low latency or higher frequency?
thanks in advance

 

frequency > timing

 

I thought it had more to do with AMD than Intel, what is your CPU? 667HZ is better than 533Mhz! What do you have unless you have AMD!

 

ahh a canuck i see... well use CPU-Z to see what type of ram your laptop supports and get w/e it says there cause if you get 5300 its only going to run @ 4200 (assuming it only supports up to 4200), usually the manufacture will have the max freq. memory that the notebook can support installed when you buy it... check the specs. of your notebook... oh and http://directcanada.com

Do me a favor! Don't Post Pictures that are above 1280X800, I do not want to scroll left/right! Please stop!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

 

as a matter of fact that picture is 1280*800 and not above...

sry but been having problems with lappy and as of yet no photoshop

 

Please stop.

 

i have AMD turion64x2 tl-52(1.6ghz) fsb=1600 and with pc2-4200 1gb(2x512) 533mhz sodimm installed.
CPU-Z says "pc2-4300 (266mhz)" and" FSB RAM "cpu/5"

which should mead 1600/5=320x2=640(correct me please if anything is wrong here)
so a 667mhz RAM should clock down to 640mhz and work or not?
and even if it does (my question is) for multitasking is it better than 533mhz RAM which has quicker timings.

thanks

 

Your laptop is running the memory stick at 667MHz, not problems.
The DDR means dual-data-rate, meaning that two signals are transmitted per clock and thus the (effective rate) = (actual clock) * 2. So for your computer : effective rate = 333Mhz * 2 = 666Mhz.

To the OP : Your notebook will most likely support the DDR2-667 (If your model is 2007, it's almost for sure). As for the memory, I think it's better to get the DDR2-667.

 

No need to insult anyone, is there?

 

Quit your whining.

 

Lets get back on track here guys!!

Yeah, you should be fine with DDR2 667 memory. The timings/clock speeds only affect programs which are memory intensive. For regular use you wont notice any differences between DDR2 533 or DDR2 667 memories.
