Timingz VS Speed AMD RAM

post #1 of 11
Thread Starter 
Which is more important.

DDR2 at like 800 with loose timings or DDR2 at 533 at tight timings for AMD.

I'm just wondering..

Timing hardly do crap. Speed is MUCH more important, especially if you are comparing DDR2-533 and DDR2-800.

For AMD, speed is more important. On Intel, timings are a little more important but speed still is very important (just not as much as AMD).

Edit: I was wrong, switch AMD and Intel around

Its the other way around. AMD's have an onboard memory controller, making timings much more important. While Intel don't (they have it on the chipset, like old Socket A AMD's) it makes speed more important for them.

nope tighter timings with AMD, Intel is the speed whore so get those timings tight and youll see a big difference

Alright, I was wrong. Going to edit to reflect it.

Also, this guide might help http://www.overclock.net/faqs/98377-...hlight=timings

If the timings are outstandingly bad, go for speed, even if on AMD. If you can get the timings pretty tight, while holding good speed, take the timings.

Like me you could spend hours reading about this on the web and still not understand it.
Hopefully I am stating this correctly.In most cases lower latencies will provide a larger performance boost then higher bandwidth. That said, there is an interaction between the two that offers even better performance. Please understand that this is based solely on my experiences but I have gotten better measurable performance from running good high speed ram, (in my case DDR2-800@4-4-4-12;1T) at it's bandwidth limit (in my case DDR2-1000) then I have from running slower ram at very low latencies.
I think that you have to find a balance between the two by experimenting and benching the results for your particular system.
I know that it is kind of a non answer but my best performance has been when using the rated timings at the highest bandwidth possible.

EDIT: You guys are quick. 7 replies in the time it took me to type mine.

TY alls, plus rep..

I was just wondering because I upgraded from DDR2 533 -> 667 but noticed a huge change in the timings, much worse. I was probably going to down clock the 667 to get some tighter timings at like 533
