LOL. my OCed speed is for gaming. the rest is just for comparison / measurement. smile.gif

then if for gaming its useless to see the results from the high CPU Overclock...its better the GPU overclock,the raptors and 2 sticks of 1GB memory tied up at 2-2-2-5 timings....

does it matter?..tighter timing will improve anything?..noobie here...

i asked this question a month ago. after getting the 2-2-2-5 RAM recently, i am able to make comparisons. just like all the sifus (i.e: kucingfight) told me, it's the speed that matters. i mean the FSB. it does not make any difference when i'm using 2-2-2-5 or 2.5-3-3-7. but with relaxed timing, i can overclock more. so in the end, i settle for speed over timing. now my 2.4c is on steroid at 3.2GHZ. brows.gif

tighter timings = better performance

not purely the clockspeed that matters, of course its nice to see your rams running at a higher speed but u gotta run some benchies to determine which actually benefits u more
but for your P4 i guess the clockspeed does matter more in the end

my opinion is more mhz with loose timing if the ram can get more higher mhz...
tight timing vs more mhz... more mhz can boost the ram speed more...
it is better to get tight timing + more mhz cause both also can give more speed

it's better if we can have both high speed and low latency at CHEAP PRICES

usually, high speed and low latency comes in expensive packaged that need to be fed in excess of 3.3V and dies out now and then. that's what u pay for it

neway, me happy with my overclockable, high speed, average latency, but most importantly - CHEAP KVR d43s...

depends on how fast ur ram can go at losse timing and how fast ur ram can run at 2-2-2 timing.....if ur ram can run more than 300 mhz wif 3-3-3 timing ..it's will beat ur ram tat ran 200mhz 2-2-2 ...

there was a review somewhere in d net...sometime ago...i think at xbitlabs

if u can get more than 260 @ 2-2-2-x ,it has the same performance compared to 275 at loose timings...but d problem is...its very hard to get more than 250 at very tight timings...

afterall,in real time everyday use,can anyone feel d difference rather than benchmarking?(please correct me if i am wrong)

i still blur with the timing

but my ram 166mhz clock to 200mhz without problem ....

not yet OC still default
wut timing is my ram

2.5-4-3-8

but now i set 2-4-3-8 run under 200mhz = PC4000

check your timings under the Memory tab
that SPD tab shows the default timings only

200mhz = DDR400 = PC3200

and yeah, tight timings + high clockspeed = the best?! shocking.gif
ZOMG now we know! doh.gif

300HTT 1.5-2-2-5 > 400HTT 3-5-4-10

300FSB 2-2-2-5 (tak semestinya) > 400 3-4-4-8

correct me if i'm wrong.... notworthy.gif

i prefer high speed, see liao more song! tongue.gif
anyway from my experience wif sisoft, tighten the timing wil giv 1-2 seconds of super 1m increase, more in 32m, but u nid to increase ram speed about 30mhz to gain same super pi sec as tight timing

high HTT doesn't make any difference, but it increases the clockspeed. thus better score is obtained because of higher clockspeed...not high HTT.

higher FSB & DDR speed does increase bandwidth score.

FSB or HTT has nothing to do with timing. THe timing is for RAM only.

Actually it's easy. the 2 in 2-3-3-7 means 2 clock delay.
The clock here actually means the clock speed of the memory.

If the memory is running at 200MHz, it has a delay of 1/200M. This delay is the same as a delay of 1 clock cycle. So the 2 here means, 1/100M second delay.

That is why when u clock higher, the effective latency actually decreases even u put CL3.0. At 300MHz (DDR600), CL3.0 delay = 3/300M = 1/100M <--- same as CL2 DDR400.

An example of the ultimate memory would be:

DDR600 @ 2-2-2-5-1T

So think about it...

question about the timings,
which of the 4 (CAS, RAS to CAS, RAS, Tras) makes the biggest difference?
i remember for P4 last time the CAS doesnt matter much, RAS to CAS is most important followed by RAS

I also forgotten, but if i recalled correctly, CAS is the most important.

You can easily test it: Run Sisoftware Sandra memory benchtest (UN-buffered). Change one of the timing by '1' (either increasing or decreasing) and see the results. wink.gif
