P5B Deluxe timings 4-4-4 > 4-4-3 > 3-3-3 ?

[deadlock7]

man ram clocks so nice in the P5B it's too bad they don't give us proper control of the timings.

Ram clocks better than 975,but i dislike 4-4-2-8!

interesting haven't tried 4-4-2 yet

It's just a bit faster than 4-4-3.

[hipro5]

May I contribute?....

A friend brought me one for Moding it, so I "play" a bit with it......

RULE No1: DON'T use 1:1 devider on this mobo.....It's NOT 975 chipset....

Take a GOOD look at the screenies below AND the LATENCY.....

















.....and AGAIN......




AS you can see, the BEST is at 4-4-4-x ......and with 4:5 OR 2:3......1:1 gives a very high latency 55 - 60ns......

Wow hipro thats a big help thanks!

What mods are you doing to it if i may ask?

edit - Also, a question, did you switch timings via memset or in bios? as bios timings seem to effect performance different then memset.

[Viss]

450 4:5 is nice. What settings/bios you used for that?

[hipro5]

I booted at 400MHz SHARP so as to keep a better strap with Cas 5-4-4-8 -6-5-10-10-10-12-disable.....I then within Windows, uped the fsb at 450MHz and played with the Ram's timmings/subtimmings....Doing so, I had a 43.2ns latency on everest and 8ns latency on S-Sandra.....Also 2007 score on winrar 3.61 benchmark.....
Winrar benchmark shows you what you've got...

Mods - simple things - Only VMCH and VICH-VTT....

@ eva2000: Put the tRRD=5.....On this mobo, tighter is not better......

Thx for all the nice tests here!

Anyone have a tip for me, why i can't use the 4:5 divider? I can not boot into windows, doesn't matter which timings or bios i use.. 9x400 and my Fatbodies @ 500MHz and with 2,4V Vdimm = no go!

With my E6400 i already handled to bench with 505MHz, but it was 1:1 and with "strange" Timings. http://img243.imageshack.us/img243/6...28smalldr3.jpg

hipro is that a 6800 running 400x9 at 4:5 ddr1000? i have been trying forever to get that is that stable or only benchable?

Fatbodies and 4:5 = 5-4-4-12-6-10-10-10-12-disable

Yes it's an X6800 one....Vdimm = 2.70Volts via DDR Maximizer as for the Corsair 8000UL Fatbodies and 2.66Volts as for the Cell-Shock 1000C4 ones...It benchies everything ....

P.S. Try PCI Latency=128 and PCI-E = 110 to 120MHz.....

[funkflix]

Fatbodies and 4:5 = 5-4-4-12-6-10-10-10-12-disable

Thx mate, but it have not worked(i forgot the 12 on the end to be honest, it was on 10). Are this the tightest timings possible with Fatbodies on 4:5 or just the timings to be sure, that it is working 100%?

Will give it a try again tomorrow, with a little bit more sleep and time..

You can pick 5-5-5-15 as well for boot....

Wow!...
Thanks for all the effort!..
Hmm.. the sub timings r very interesting...
I'm running my 6403 @ 3-4-3-4-3-20-5-9-6-9
gonna try out ur tests...
Thou my board is only a P5Bvanilla..

Tested that all before, but can't get it working here, thanks anyway..

[v_parrello]

Very interesting thread guys! Thanks a lot!

I have two questions for you:
- is it true for all 965 mobos?
- what about mobos with 975 chipset? They perform in the same way?

Tanks in advance for your answers.

[eva2000]

@ eva2000: Put the tRRD=5.....On this mobo, tighter is not better......

thanks for the tip mate

[»X$«êdên]

YAY thank you!
I have this Memory:OCZ Platinum Revision, 2 2GB, (PC2 6400), Rated @ 4-4-4-15; and it seems to like that at 266 if EVER...
@333 1:1 my core temp is 62 / 58 since the motherboard switch with added fans.
I need to get that everest!

[deadlock7]

Hmm..i was playing with sandra and 4-4-2 gave me better results than 4-4-4.I tried everest and spi and i found out that Hipro is 100% right.Thanks for the tips dude..

[Millyons]

for me out of all of them 3-4-4-x was the best for PI 1mb

[cpulloverclock]

the best timings for high frequency memory with a P5B with is 3-4-2-4-4-3-20-1

the problem about 3-3-3 and 3-4-4-3 is known, it's why I didn't use them when I benched :o

just a P5B issue

Cool thanks again hipro, any chance you havea picture of that VICH-VTT mod, ive never seen it.

[pentium777]

Thank you for all that testing although I am on 680i I'd still like to ensure I am not missing anything? running that 4:5 and looser timings but higher DDR2 speeds provided much better results in bench, gaming and everything you did. So why would I want to run 3-3-3 if I can loosen and run higher DDR2 speed and provide better overall system performance?

What about when you boot at 400mhz

[alexio]

Has anybody actually tried to hardcode tighter timings in the SPD? I think doing this and booting with SPD settings should fix the problem.

What do you guys think?
