PQI Review, Looser = faster FSB?

Post by dcFields »

I read the review of PQI memory - Enthusiast Memory.
I have the same Mo Bd , a P4C800E Delux with an ATI AIW-9800pro,
a couple of Seagate 160Gb sata drives in a stripe set
and a maxtor 60gb drive with my O.S.
I need more Memory for my video editing.
I also like to play games. 8)

In the review he used looser timing and got a faster FSB.
It seems counterintuitive and I'm so confused. :?
I experimented with timing when I built this system.
I'm overclocking my system P4HT 3.2G (800mhz) to about 3.4G.
I've gotten the timing as tight as I could while maintaining stability.
Would my system actually preform better with looser timing?

I read the post "higher fsb or tighter timings".
The answer sounded like I would have to go through hours of benchmarks to find the answer.
Is there an easy (understandable) answer?

P.S. do some posts completely dissagree or what?
"Wow, large performance gains from upgrading to 2GB RAM??!!" (the content is kinda obvious)
other posts say 1Gb(x2) kits are slow
because the 1Gb memorys aren't very fast.
Should I go with smaller sticks and use all 4 slots?

Thank you in advance for your help

Since your using Intel...Timings don't matter too much....The Pentium 4 LOVES memory bamdwidth, and that's raw bandwidth speed. IF you can increase the FSB more (and OC more) then do it if it's stable....
Whatever you do, don't use a memory divider and low latency with the P4...IT will kill performance. Aslong as the RAM runs 1:1 with the CPU FSB (forget timings) then you should be cool 8)
Only AMD responds well to memory timings....(or ddr2 @ high MHz)

SO forget timings? Run loose and have a faster fsb that will be better for the intel beast?

I can deal with that, but I'd still like an explanation if anyone has one. Feel free to be technical I used to work as a rocket scientist.

tighter timings is usually always better for performance, so in all honesty try to find your happy medium.

Go for your Highest overclock running the ram with the CPU.....Once you find the CPU's max...then lower timings to squeeze the last bit of performance out....As Apop said timings will increase performance, but MHz is ALWAYS more important with Intels current CPU's.......Not say timing won't increase performance.....

Intel responds less to timings because the memory controller is on the motherboard....This by default will increase latencies between ram and cpu..
Intel designed their chips with this in mind....
AMD have the memory controller on the cpu...so there is a direct link between the cpu and the memory, the controller also runs at the full speed of the CPU....therefore when the (amd) cpu requires data, latency is more improtant and the cpu wants data now.....not Like Intel when the CPU sends the request to the memory controller and sits and waits.....

In other words......latencies determines how fast ram responds to a request.....now with Intel the ram can respond as quick as it likes....but it still has to go through a memory controller on the motherboard, this always slows down memory access....normally enough not to make ultra low latencies noticeable.......

I hope this kinda clears some things up?
