680i folks tighten those sub timings for 975x chipset like performance

System:

560mhz 4-3-3-4 2T 3-1-3-6-34 at 2.5v vdimm

Yup tight ass main and sub timings on Asus 680i Striker really do make a huge difference. Who would of thought I could pull off sub 13min 30s Super Pi 32M times at 3600mhz with a 680i chipset motherboard without even clocking memory above 560mhz (DDR2-1120) speeds!

Jumped all the way to 560mhz 4-3-3-4 2T with sub timings of 3-1-3-6-34 at 2.5v vdimm bios set. According to memtest86+ v1.70, reported bandwidth at 560mhz 4-3-3-4 2T was 5413MB/s versus at 533mhz 4-3-3-4 2T of 5209MB/s.

All I can say is bloody fast for 680i chipset considering 32M time at 3600mhz is pretty much right up there with 975x chipset as far as i can see :D

eva you're quite the 680i guru. :fact:

Now I've got to see if I can tighten up my timings.

Thanks for the all work you have done with the Striker/680i. :toast:

So how is Striker now in generally?

It had a LOT of issues in the beginning. Has it matured to the point where $400+ is worth it?

Thanks Coroner Kyle :)

Speederlander, only time you want to get Striker is

1. You plan to run SLI

and

2. You plan to tweak and overclock your memory - the striker onboard reset switches and diagnostic LCD on I/O port help if you have issues.

If you plan to run SLI but only intend a mild overclock above stock ram/cpu speeds maybe P5N32-E Plus board would be better ? Although, Striker does have better quality components on it than P5N32-E Plus board from what i read.

The only real issue I have is with the vcore undervolt in 0402 bios, but I can live with that as opposed to less stability with higher bioses and less mem/cpu clock with 1002 bios which fixes the vcore undervolt issue.

Don't have any problems even running 4x1GB G.Skill 6400PHU2 Micron D9GMH @500mhz 4-4-4-12 at 2.25v vdimm http://i4memory.com/showthread.php?t=3744

But for other intended purposes, I'd pick a 965P/975x chipset based board if you don't run SLI.

Thanks for that. Yeah, probably won't run SLI. My chosen focus is on CPUs rather than memory or video cards. Can't afford to play in all three areas. ;)

Managed to clock ram up to 600mhz 5-3-3-3 2T but with even further tighten the sub timings even more but had to loosen CAS from 4 to 5 in order to keep vdimm at 2.5v bios set ceiling (within OCZ warrantied max vdimm of 2.52v) :)

Memtest86+ v1.70 reported bandwidth

• @533mhz 4-3-3-4 2T 3-1-3-6-30 at 2.35v vdimm = 5,209MB/s

Great info for 680i clockers but..

I'm little bit confused. For the frequency you're getting higher bandwidth per mhz at 533MHz.

9.773B/s/Hz for 533
9.666B/s/Hz for 560

Were you unable to exceed 533 with the looser timings? Or did you loosen timings to get higher than 533? Do you recall which sub-timings you used at 533MHz?

However, I know memtest isn't the most accurate for bandwidth as it's measurement algorithm is quite simplistic. :p:

Keep up the good work! :toast:

EDIT: WOW just noticed the primary timings and sub-timings in those 600MHz shots :o

Amazing Work there EVA!! Will play around my setup tonite :)

thanks guys reason why bandwidth/mhz drops slightly is all bandwidth has to go through FSB and at 400FSB there's only so much that can be utilised as you clock memory higher. If you upped the FSB more than more bandwidth can be utilised :)

Simple illustration is everest bandwidth reported above for read bandwidth at 560mhz and 600mhz is ~200MB/s difference same as memtest...

Ahh I get it :)

thanks for explaining eva.

4000Mhz - 10x400FSB / 3950mhz - 10x395FSB

The Asus 680i Striker Extreme just runs my X6800 hotter than on Asus P5B Deluxe at higher vcore settings ~10-13C hotter at idle.

I tried X6800 @10x400FSB = 4000Mhz at 1.56-1.62v vcore and idle coretemp reported 57-67C versus same X6800 on Asus P5B Deluxe at 4092mhz at 1.65v vcore only reporting coretemps idle at 45-47C.

So only could manage 1M times for X6800 @4000mhz at 1.6v (1.57v load) on Asus 680i Striker Extreme. Higher vcore just meant reboots in windows under load (maybe vdroop too much at higher vcore like on P5B Deluxe ? )

Everest Bandwidth with 42.7ns latency
http://fileshosts.com/intel/Asus/680..._bandwidth.png

But at much lower vcore of 1.56v idle/1.54v load, coretemp reports more reasonable idle temps and I can manage 3967-3972mhz at 1.56v idle for 32M with lower mem clocks but once hit 600mhz 5-3-3-x timings seems tight sub timings cause instability until I drop cpu down to 3950mhz at 1.57v idle!

@592.5mhz 5-3-3-5 3-1-6-8-28 2T timings at 2.5v vdimm bios set, Memtest86+ v1.70 reports 5540MB/s memory bandwidth.

nice results eva!

what about the p5n32-e non-plus?

isn't the non-plus almost identical to the striker?

thanks guys

the p5n32-e non-plus is almost identical but AFAIK, uses less quality components/missing some caps compared with striker.

I couldn't get under 13min, but thanks for info here are my results.

Maybe someone can give a evga or other reference board a try. Mine was done on an ABit IN9 32 Max which is probably too expensive as well.

Seems like a pretty good board for $200 +/-.

excellent stuff The Nemesis

Yup NapalmV5, tweaked is better than not tweaked on any platform :D

Nice work!
I will spend some time playing with the settings

1T tops out for me at 450mhz 4-3-3-4 1T with memtest bandwidth only at 5028-5209MB/s which is short of what 600mhz 5-3-3-3 2T is at 5400+ MB/s. And i can test higher at 640mhz 5-4-3-x 2T later so definitely for my memory 2T will end up faster than max 1T

Althow I managed to reach the speed and the timmings with my Supertalent PC6400C5(2.55vdimm),I got a slower time.I am running on Windows XP lite(fresh install)with major tweaks on(maxmem,system cache,realime...).Have you done something with the other timmings in bios(tREF/tRD/Acync Latency):confused:
I have left them in auto.I also have to say that I had to set the NB voltage to 1.6v to make the system able to finish spi.

tRef and async left at auto, trd you can play with ;) :D

520mhz 4-3-3-4 2-1-2-6-20 2T at 2.3v

Now to look for a compromise between max memory clocks with high vdimm and more reasonable lower vdimm and suitable memory clocks which have very tight sub timings.

I ended up with 520mhz 4-3-3-4 2-1-2-6-20 2T at 2.3v vdimm bios set. Only ~1.39 seconds slower in 32M Super Pi than 533mhz 4-3-3-4 3-1-3-6-30 2T at 2.35v run but uses 0.05 vdimm less! Interestingly, 520mhz run was faster in 1M Super Pi due to tighter sub timings at 13.938s (520mhz) vs 13.969s (533mhz).

nope.. 2.5v for benching only... you'd want to keep vdimm under 2.3-2.35v if possible.. don't go crazy on voltages

If I loosen sub timings a bit more I can do 533mhz 4-3-3-4 easy at 2.3v vdimm. Tigther sub timings = more vdimm and NB volts needed.

This is the best I could do on 1T topped up phil by a sliver :D:D:D
This is also at 3.6ghz
I can't manage to do anything on 2T with this 1002 bios.

Yes!. 680i loves tight memory timings and is exellent memory overclocking board.
I have 2gb dualchannel D9D running DDR950@4-3-3-1T and its only at 2,25V!
Im not using dualcore CPU yet. Im running Celeron D356@4,8Ghz. 1,47V
PC does Spi under 29sec. Friend is running badaxe2 and same celeron with same D9D. He can get timings only ddr950 4-4-4-2T and he has Spi time only ~31sec.

very nice tight timings.. :)

eva or anyone else with the striker board...

will the p5n32-e sli plus be able to do this or does the nb chip play a factor since the p5n32-e plus and striker/p5n32-e non-plus have different NB chips?

From what I've been reading, there is virtually no performance difference between the boards.

hey eva what did you set your trd to?

Tip of the cap to Eva2000 for yet another great thread. I finally got around to playing with my eVGA mobo (two months late) and the fun factor on memory is very high! I'm still testing out CAS5 and have started to tighten the secondary timings. However (little bit off topic) I have a question regarding tRTC and if there is a big jump in voltage required to drop it down to 3. My board violently objected at the same vdimm and a quick .05 jump didn't change a thing. I'll try to push a bit more on speed and go after the secondary timings again and include Memset in the screenshot so you can see them when I'm done. In the meantime here's where I am. Suggestions very welcome. :D I had the wrong tab up on the CPU-Z shot that had the memory ID. These stick are the ones from the Deals section titled BUFFALO Firestix 2GB (2 x 1GB) DDR2 800 (PC2 6400) $174.98

very nice memory for a price like that.. :) thanks for sharing..

thanks guys

gundamit nice clocks there - and yes tRCD/tRTC of 3 needs more vdimm which further supports the fact that tRCD of 3 is faster than 4 value and is in fact real .. maybe ?

ineedaname, try between 1 and 7... 7 i think is default value when AUTO is set for tRD
