The official memory latency benchmark competition

[Ketxxx]

list updated. im gonna try and find a few more tests to run to make things more interesting

 

[p-jack]

update

slightly higher clocks + tighter timings @ 2,85V...

below 40ns, yea!

 

[DRDNA]

37.0 Looks like a 2nd placer

 

[cdawall]

7. cdawall - 48.4ns 480MHz 3-3-3-7 CR?

CR1


got some intel scores as well
all ddr400@400
set up 1 p4 3.2ghz s478 i865 chipset ram ddr400@400 3-3-3-8-cr1

set up 2 pentium D 930 @ 3.3ghz i865 chipset ddr400@428 3-3-3-8-cr1

 

[tofu]

Guess I'm taking First Place in the Intel DDR1 systems ,

with a latency of 74.1ns

CPU-Z validation link: http://valid.x86-secret.com/show_oc?id=164589

EDIT: intel 865pe does not show command rate, but im running 4 dimms, so lets just say 2 for now

 

[Murasame]

Got the timings down very slightly, but moved up two spots on the benchmark above the opteron and P4EE.

 

[jms45]

4x 512mb Corsiar XMS2 675 @ 800 4-4-4-12-CR2 2.2v

 

[Ketxxx]

list updated. any requests for additional benchmarks ppl would like to see? majority wins

sandra XI mem bench

 

[Steevo]

We need to enforce system stability with these benchmarks. I can run the 39ns too but my system is a bit unstable and I get one RAM error during memtest.

 

[GIGGLA]

Wow I did'nt know you can run a Pentium Dual Core on a 865G chipset will this cpu run on a 865PE chipset? Anyway here is my 865PE chipset with a 3.4C Northwood all stock speed. I guess this gives me first place in Intel DDR1? Tofu did you know you can turn PAT on even in overclocked mode well you can and it gives some whopping memory performance. But maybe the PAT is only for the 865 "PE" (some brands) and 875P all brands.

another p4 system s478 northwood 2.6ghz w/ HT dual channel ddr400 3-3-3-8-cr1

True, I can get my timings down when I run my C2D@3.8GHz, but it's not stable.

 

[Alcpone]

Here's mine!

 

[Solaris17]

ok kett new stats this time muchhhh better!! take alook.

 

[cdawall]

woop woop

 

[Ketxxx]

ok I'll update the list as soon as I can ppl. I'm working on them ADI1988B SoundMAX drivers again and yes, so far at least, its going very, very well.

In the meantime if anyone wants to cut n paste to update by all means go ahead.

More placings will be added if this grows in popularity. Post away folks.

Cheers CD

My CR is 2

I should be in 1st place in Intel DDR 1 systems with my latency at 71 nano seconds. As shown in post #111 above. After clicking on the attachment click the image once to see better. Thanks

Yes, check my CPU-Z screenshot, PAT is definitely on. Without PAT, <80ns is largely impossible

Ill make another run for that 1st place lol. This time though, I'll run it with 2 Hynix D5 dimms at a nice 275mhz (DDR550) 2.5-4-4-7 3.3V, I hope that'll myself back into first

 

[cliffinokc]

how can i post mine?
