Update: Asus 680i Observations Part 2: Large Pics Warning....

Since I've had more time to mess with the 680i lately, I've found a few more interesting observations that may help some people with these boards.

first off though, I want to say, I am not the expert on these boards, people often ask me questions about this board, that I just have no answer for...
often people have troubles that I simply havent had, so I can't do anything more then give general advice.
so what works for me, isn't always gonna help you, since we all have varying degrees of experience, and very different hardware.
these are just my latest observations, on a very unusual chipset...

first off, some pics to show 500+ isn't impossible with these boards.

this is a straight boot shot.
no tweaks for the super pi test, other then whats in bios.
I am not much of a tweaker when it comes to Super Pi, as I am not usually looking to break records, except my own personal ones.
no clockgen used, not cause I wouldnt use one... I just havent found one for these boards yet. :D

http://www.xtremesystems.org/forums/...1&d=1170451390

just a bandwidth shot.
booted at cas 5-4-4-10-10 TRC and rest at auto.
TRC and TRAS were tweaked with Memset, just alittle.

http://www.xtremesystems.org/forums/...1&d=1170364942

this is my most tweaked shot, with me trying to go for a personal best in Pifast, with this particular processor.
unfortunatly I am just at the limit of what this CPU will do with only 1.6 volts... I need to go back to bios 0302 where the Vcore actually worked...
bios 0702 works mostly, except the Vcore doesnt go above 1.58 volts anymore... seems asus just screws up this board more everytime they release a new bios.
my advice, stick with bios 0302 if you got it.

oh yeah, about PI Fast.
theres 2 major versions out, version 4.1 which is the version supported by Hexus currently. Version 4.3 is out, but its alot faster then version 4.1 by about 5 seconds.
if you ever see a PiFast score thats unusually high, chances are they are using version 4.3 to get the upper hand.

http://www.xtremesystems.org/forums/...1&d=1170364942

this is just Aquamark3 at 4.1 ghz, nothing too interesting about this shot, just alittle 3D for the hell of it.

8800 GTX at 660/1060.
Mushkin PC6400 at 1240 or 1250 mhz (forget what it really was).
cas 5-4-4-10, TRC 10, rest at Auto.
E6400 at 4.1 ghz.

Now, Observations.

heres the best tip I gained for myself recently.

Dividers and FSB.

see, I've always noticed this board likes even numbers.

meaning 2000 FSB (500 FSB's) will often boot, if you use a even number for your ram.

meanning 2000 by 1000mhz ram, will boot.

2000 x 1139 mhz, will not boot.

I've always suspected this board has some very strong dividers, and some very weak dividers, and I think I've narrowed it down to 2 dividers that just seem to work really really well for me.

the 5:6 divider, and the 9:11 divider.
you can only get these from the Unlinked mode, but you probably figured that out already if you seen the inside of these bioses and saw you can't manually select what divider you get when entering in a unlinked ram speed.

in particular, the 5:6 divider is extremely strong, and for me, offers great stability....
but theres a huge draw back.

to do successful 500 FSB's with the 5:6 divider, you need ram that can do 1200 mhz very easy on these boards.

(FSB x 1.2 = Ram speed if using the 5:6 divider)

I will give you an example of how strange the dividers effect your stability.

8 x 500 = for 4 ghz.

unlinked.

set my own ram to 1200 mhz = boot, runs solid, even with tight latency.

same speed and FSB, but set ram to 800, and any latency = no boot... ever.

why? I have no idea... if it boots at 500 and 1200 mhz, why wouldnt it boot at 500 and 800 mhz ram? I have no idea... it just wont for me.
latency and voltage dont matter... it just seems theres a "weak" divider that just doesn't wanna work at that setting.

when I started to see this, I started really experimenting...

500 FSB - 800 mhz ram = no boot.
500 FSB - 1000 mhz ram = works fine.
500 FSB - 1100 mhz ram = boots, but very touchy.
500 FSB - 1200 mhz ram = solid works great.
500 FSB - 1250 mhz ram = solid, works fine, just need alittle voltage.
500 FSB - 1300 mhz ram = boots, but unstable, not usable for long term (haha... I cant honestly expect 1300 mhz to be stable)

now heres the monkey wrench...

1200 was stable at 500...

but try 400 FSB - 1200 mhz ram... and it wont boot.

again, theres some welll just touchy dividers there that just dont seem to like various combinations of FSB and ram.

but heres where it gets truely strange.

to break a 500 FSB easily... you need to have your ram really fast too.
500 FSB + low latency, low speed ram = glitchy, tempermental, doesnt wanna remain stable for long...
but 500 + high speed medium latency ram = very easy to get stable, assuming of course the ram can actually remain stable at high speeds.

Plainly put...

this board already has a very very high learning curve to it, that much was obvious from day 1, however, now beginning to see that theres various dividers and FSB combinations that just wont play nice, can make overclocking with this board, successfully a whole lot of trial and error, which alot of people just either wont take the time to do... or will give up in frustration with.

a 400 FSB is rather easy, regaurdless of experience level.
but 500+ is definatly gonna take some patience, unless you just happen to get a miracle board tha will do it nice and easy.

so basically, be patient, and try combinations with your ram and FSB that seem like they may not normally work.
sometimes you will be surprised...

TRFC and D9.

D9GMH in my opinion is best overall all around ram I know of.
its highly resilliant to huge voltages, will do rather high MHz on the RD600, 680i, and the 965 chipsets, which I can confirm cause I have all these boards here, and have tried.
its great for low latencies, and just has a great range of latency and MHz to it. I've used about 5 sets of different D9 so far, and I've always been impressed with the variety of OCs one can get from it.

well, the D9GMH, seems to actually alittle unusual on the 680i chipset... and I cant say I know why... cause it doesnt do this on the RD600 or 965 chipsets.

it doesnt like high voltages... nor does it need it.
thats where it gets truely strange...

see, D9GMH, on the 965 chipset, will typically need about 2.5 volts or more to get 1200 mhz... and that unstable usually, or short term stability.

and it will need nearly 3 volts in most cases to do things like cas 3 at 1000 mhz.

but all that goes out the window on the 680i.

680i, I can get 1250 mhz at 2.25 volts easily stable enough for benchmarks and such.
1200 mhz at 2.25 volts very solid, for day to day use.
thats incredible...

but heres where it gets weird even again.
normal D9GMH seems to need about 3 volts usually to get cas 3 at 1 Ghz.
atleast on the 965 chipset.... but on the 680i... only 2.5 volts or close.

but theres a problem...
D9GMH, atleast in the 3 sets I still currently have, in this board, simply dont like voltages above 2.4 volts.

thats truely strange for a set of ram, I myself have taken to well above 3.4 volts and know has a huge resilliance to high voltages.

so D9GMH just seems to act very strange on this board...
it doesnt need much voltage, and doesnt seem to need it.
works great at 1T, but just plain old wont boot if I try 2.8 volts on it with this board.

so basically...

with how just about every company out right now uses some form of D9, especially D9GMH, chances are high if you have quality ram, you might have some luck with this tip...

if your having troubles with your D9 and your trying to get it stable by adding voltage...

do the opposite, and keep the same speed... just lower the voltage.
believe me.... if I thought I could do 1250 mhz easily at 2.3 volts on my P5B deluxe, I'd think I was dreaming.
when I first started trying the 680i, I did exactly what I always did on the 965... cant get it stable... add more voltage.
but with the 680i do the opposite...
cant get your ram stable?
go lower...
it sounds weird, but I have 3 sets of ram here, that all do the same thing...
less voltage - gets me better stability.


ok, I didnt forget the TRFC.

the TRFC on the 965 chipset, is limited to about 42 tops... which people like to say is slow.
so the tendency is to try to get lower, at 35, then 30 and so on...
but honestly, TRFC really isnt a ram setting thats ever gained me much in any benchmark or game, its more a psychological number...
42 just sounds really really high, and as overclockers, we dont like things that sound slow, haha... :D

but on 680i.... if 42 sounds slow to you, wait till you see TRFC of 100+... cause its there and you can use it...

now, coming from the 965 chipset, my natural tendency is to wanna take the TRFC to 42 or less... just like my P5B deluxe.
while this will work... your gonna find out something real quick...

you will get alot more "freezes" by manually setting the TRFC, then if you just let it be at Auto.

Auto TRFC tends to set the TRFC at 66 if your using 1200+ mhz on the ram.

stability is alot easier to maintain, at any ram speed, if you let the board figure then TRFC instead of trying to manually force it to a setting you want.

remember...
sure, it gives you bragging rights if you think TRFC of 20 or lower is great for some benchmark, and you can get it there, and others cant... but if your at all like me... you gotta live with these settings everyday all day.
theres more to overclocking, then just benchmark speeds, and if your just increasing your boards frequency of freezes, cause you think TRFC of 66 or whatever is too high for you to cope with...
then you might as well get use to random freezes and crashes.

otherwise, for the rest of us, that dont really want to deal with the psychology of numbers, and bragging, and just want stability...

its just best to leave TRFC alone on these boards.

for me, any TRFC setting I set manually, just results in occassional freezing.... when it be 3 hours from now, or 3 minutes, wont matter, cause it always happens.

but leave the TRFC at Auto... and you can run all day, with little to no chances of freezes... assuming of course, that your actually running a stable overclock.

Last Observation...

450+ isnt impossible or even hard with the 680i and Quad Core.
I've done it, and done it stable on air...
but that was a few weeks ago when I first got my quad core.
I plan to put that CPU back in this board, and do it again... to show it definatly can be done.

so this spots reserved for alittle Quad Core stuff. :p:

Update:

After Much trial and error... and some advice from a friend Yoxxy, testing some voltages and 1000 reboots...

I found the trick to 450+
but its not a fun thing to do, cause it has a huge drawback...

first off, high FSB's seem to respond to the 1.2 VHT voltage, to above 1.5 volts, and the NB voltage to above 1.7 volts.
you need these voltages high to get it bootable most of the time...

but still it will not wanna boot sometimes, and theres a simple trick to fix that.

power down, and power up.
no reset, just power down and power up from a cold boot.
this seems to work far better then the soft reset from bios.

Lastly,

Lower Multipliers are far easier to boot, then high mulipliers.

6x = Hard.
7x = Harder...
8x = Very Hard...

any higher then this, I dont know.
my CPU only goes to 8X max.

the advantage of running 6 x 450 = 2.7 ghz

versus, 8 x 333 = 2.66 ghz...

besides the obvious, is that once you pass about 430 on the FSB, the latency of the chipset is greatly loosend, so then you get the chance to run 1200 and 1300 Mhz on the ram.

so it's not entirely useless, but not easy still...

but it is possible, just not what I was hoping for.

nice findings.im still testing ,but sofar ,500fsb and unlinked ram at 400 3 3 3 8 timmings 1T is running stabil . how far up kan you go on 1T ? i feel the system is much quicker with tighter timmings and not so high mhz on the ram.im running with 701 biose which came with the mb ,and it seems that voltages are working fine,besides a bit of drop on the vcore .

Fantastic work Kunaak, I shall see how these finding weigh up on the Abit IN9, I've found this chipset to be quite quirky but always thought 1:1 was a safe bet in terms of dividers, judging by your findings I'll have to be a little more careful!

As you say it very much is a case of throw the rule book out the window!

Worth reading, good info. Thanks Kunaak :toast:

Thanks, this helped :D

Good times! :toast:

Awesome info Kunaak! :toast:

I for one, can't wait for more Quad Core results and tweaking guidance! :D

Good stuff Kunaak...I'll have an IN9 tomorrow and maybe some of your tips will apply. I had an evga for less than a week and it "seemed" to have a lot of dead spots and maybe those dead spots were really from the memory dividers. At least I'll have some ideas of what to look for and not lock my poor little brain into a path of conventional wisdom :brick:

About a week ago my 680i crashed. I was using a Vcore of 1.60V to get my E6400 running stable at fsb 400. My memory was at ddr 1000 at 2.2V. When I ran Memtest86+ v1.70 I got all kind of errors. The system was stable with another set of memory.

A few days later I'm working on the text for a rma when I decided that I needed more information. I reinstalled my Crucial Ballistix DDR2-1000 memory and to my suprise I got no errors. At first I'm wondering if they healed themself but I soon realized that I forgot to change the memory voltage from 1.90V to 2.2V.

For the past few days I've been trying to find what voltage will cause my DDR2-1000 memory to fail and now these observations by Kunaak.

Up to this point I haven't been able to get my E6400 stable past a fsb 400 on this 680i. In the next few days I'll see if this E6400 can go any higher using these observations.

one of the most important lessons that we all tend to forget, is sometimes, voltage only makes things worse, not better.

my Quad core is the same way...
I was pulling my hair out trying to get 3.6 ghz stable, and just kept upping the voltage from 1.5 to 1.55 and 1.6 volts and so on...
then one day I just started going backwards... lower the voltage, and then prime.

I found that it didnt take the initial 1.5 volts I thought, but 1.38 volts to get the 3.6 ghz stable.
see, at 1.5 volts, I am simply overloading CPU and cooling becomes ineffective when messing with 4 cores, thats alot of heat to try and cool.
1.4 or less turned out to be the sweet spot.

even my old Corsair 3500LL, that ram was the strangest DDR I ever seen.
like always, I just kept trying to get higher voltages to solve the problems...
then I just started trying to go lower and lower.

by the time I was done, I was using 2.25 volts, and getting cas 2.5-3-2-1 and 1T stable, at 254 HTT speeds.

you can see all my results from that ram here, in which theres DDR1 doing DDR2 voltages...

it was truely the strangest ram I ever seen... even to this day.

http://www.xtremesystems.org/forums/...hlight=corsair

voltage, doesn't always solve the problem.
so be willing to try less, that can yield some interesting surprises sometimes.

Yeah, that is an old habit...reach for voltage first, ask questions later ;)

The download page for PiFast only lists version 4.3 so unless you have an alternate site it looks like I'll have faster times.:D Actually using Google I found this link that is for version 4.1...

http://files.aoaforums.com/I1652-hexus_pifast.zip.html

Also your PiFast screenshot doesn't show your input choices. I noticed in the zip file there's a file hexus.txt that I'm guessing are your input choices. Am I correct?

Wonderful article. Thanks for the effort. :) :) :)

Thanks so much Kunaak, you verified something I have suspected about this board and memory voltage, I have the PC6400C5 from corsair, the promo stuff that corsair told me to run @ 2.1V on the board, but I always had stability issues at that voltage, dropped it down to 1.9 and was able to get them very stable with cas5 settings 5-5-5-15 @ 950mhz, ran that for 3 days. Company of heroes for many hours, no problems, 12 hours blend prime stable.

My crucial pc8000 I am currently running @960 4-4-4-8 @ 2.0V, not the rated 2.2V, also 12 hours blend prime stable. And 3d stable as well.

All of these are at 400fsb x9 multi on an E6600 @ 1.4V bios, so really about 1.35

I have never been able to get 1T on either set of dimms to boot from the bios. I am by no means knowledgable about memory overclocking, I tend to like lower mhz with tighter timings, and lower voltage anyway.

Thanks for the great post, I look forward to abit releasing a new bios for my board so I can get through the massive hole in the fsb for me. I cannot boot anything between 401-430, abit has issued a statement through an unstable bios changelog that never made it to release that they are aware of the holes, and are working to resolve them.

Thanks again, great read.

Very good writeup Kunaak...useful stuff, same as your last one.

Kunaak A question thou...did you change you NB/SB cooling to acheive theese results....or are you still on stock cooling..?


And a question to anyone using E6600 or higher cpus..have anyone been having problems running 390-410mhz FSB on multi. 9x..or anyother multi. for that matter(except from the post above)
Because I can´t for the love of my life get it working at 400 FSB...tried both multi. 9 and 8...at multi 8 it posts but then freezes.

3600 no worries, FSB for mine is 452fsb now (bootable from bios), but will need to replace the northbridge cooling, waterkit being installed soon. anyone got

Look at the voltages mate on my screenie maybe you got some wrong

http://www.xtremesystems.org/forums/...1&d=1170285458

That's some really interesting info, Kunaak, thanks for help!

@ Naughtyboy: I tried several times to boot at 400x9 or 400x8 and it always froze, until yesterday when I read Kunaak's first post (he was writing the rest at the very moment) and some strange thought struck me that I should OC now, and I tried, and lo! it booted fine :eek: but the sound was messed up so i only took a cpu-z screenie and spi and turned it off.
If you have problems try what Kunaak said before: cold boot - the board doesn't want to boot at first time you set high fsb.

OK, this was one of the theoretical questions in my mind when I moved to c2d platform.

What is the role of mem controller or something in that line? I even opened a thread about it without much interest on the topic.

In my mind here is the culprit (rather than a divider problem):

at fsb=400 with tight nb latencies (1066 strap), somehow cpu can't hold fast ram speeds at the same time.

at fsb=500 (due to relaxed nb latencies), cpu is able to run the ram at 1200mhz.

It reminds me of socket 939 platform (it is almost impossible to merge maximum ram speed with maximum cpu speed).

Any insights on this idea on c2d's or was it already a known issue?

Yeah I got it working now....but in a strange way. I read this post and said to my self -"I´m gonna get this baby working"
So I went at it...but nothing seemed to work..no matter what I did it simply just either frooze at post or didn´t boot at all....until someone or something ;) told me to try the 5:6 divider Kunaak was talking about. I set 400FSB unliked and memory at 480...saved and voliá it booted and went straight to windows..ran SPI32M without a glitch.
And now I can boot at 400fsb regardless of what other settings I use....this s***t beats me for sure.....have no clue what was wrong.

dont feel bad...

I think I've spent well over over 150 hours with this board, in bios alone... I mean doing nothing, not a single thing... other then tweaking one setting, and seeing if it booted.
try another, and see what happend.
then seeing if I could recreate the failures... and try to figure out why they happend....

and even after all this time... I really can't say I figured this board inside and out... its definatly a finicky board, but theres a whole lot of potential in the board.... it just takes alot of trial and error figuring it out...

if anything I do helps you, thats cool, thats what I like to hear.

I like that the 5:6 divider worked so well for you, that gives me abit more confidence that I am onto something with the "some dividers are stronger then others" idea of mine...
which just makes me wanna try it more.

you may very well be onto something...
I really didnt test the chipset latencie this time around, since I really just was focusing on 500+ on the FSB.

but now 400 and high ram speeds is definatly something I need to try now.

if 1200mhz+ ram is as easy at 400 or even 300... as it is with 500 FSB's. then that might just show that the latencie of the chipset isnt whats determining the OC ability of the ram...
or vice versa, so its definatly something to look into.

I will give that a shot too...

but the thing I wonder is...
see, I know the 5:6 divider is very strong...
but when trying to run say 8 x 400 or even 8 x 300... and 1200 mhz ram... what dividers will I get? will the dividers be strong ones... or weak?

cause if the chipset latency was the only thing making 1200 mhz possible...
then all dividers regaurdless would be "strong".... but thats not happening.
alot of ram/FSB combinations past 500 just simply wont work...

man... now I feel like I am trying to figure out the whole "what came first, the chicken or the egg" theory....

Kunaak, thank you very much for your work.

I'm tweaking the board as we speak for an upcoming review, and to say it has a steep learning curve is just an understatement :D

Many of the things you talk about are also true in my experience, especially the D9 tweaking is very much as you say :) The only thing I absolutely cannot confirm is the Quad core results : I'm still struggling to get 330FSB stable with my QX6700, and don't really know what's holding me back... Have to work some more on the quad though, as I feel more time brings more answers with this board :D

Hi , thanks for the tips and tricks i have gone upward from 500 - 600 Mhz on my ram in one go , as like yours mine wouldnt boot at 510 , 520 ect but at 600 its fine running ram at 5-4-4-12 so very pleased

Great informative post! Well done Kunaak! :toast:

Have you tried 4x1 gig sticks yet?

Yeah it seemse strong here to...stability is a fact.
However what puzzles me is that after using that divider I am able to boot at 400mhz with settings it wouldn´t even boot before.

no real puzzle...

you got a divider thats now stable.
see, most bioses over the years have had really solid and really hard to work with dividers...

like the old Asus P4P800... great at 1:1 and 5:4... hard as hell to work with 3:2.

Asus P5B Deluxe.

all ratios solid, except 4:5...
just flat out buggy and hard to keep stable in most cases.
works great at mild FSB's but you lose OC ability quick if you try too much.

DFI 975X... 1:1 was pretty horrible (in the early bioses) and 4:3 was amazing. (only Conroe board I tried that had lower then 1:1 ratios so far)
but like always DFI came back and made that board pretty nice, after thier latest update, with alittle help from Oskar, now its not uncommon to see people doing 440+ on that board.

same is true with this board...

find the best dividers, and go with it.
test them.
5:6 works great for me, and a few others, but I also hinted that 9:11 divider works pretty damn good for me too, why not give that one a try?
might work good for you too. :)

Kunnak Here´s another confirmation of your 5:6 theory :)
This is all done with an ambient temp at 17-18" C...TT Big Typhoon VX for the cpu and Thermalright HR-05-SLI on the NB and SB

http://goto.glocalnet.net/mrazster/P...oc_2_thumb.jpg

And here´s a Cpu-Z Validitation



I also tried max FSB. At this speed the NB had serious problems holding lower latencies...couldn´t run anything than AUTO setting, even thoug I set the same values manualy. Here´s a pic:

http://goto.glocalnet.net/mrazster/P..._fsb_thumb.jpg


Strange thing is resluts below is max FSB for suicide shoots...only 1mhz higher and little tighter timings than the pic above with SPI16M. Usually there would be more headroom between max SS and benchable numbers. I tried both higher and lower voltage...I also tried a fan with higher cfm rate and I tried diffirent dividers and memsettings...but it just wouldn´t boot higher.

And here´s the Cpu-Z Validitation for max FSB SS

that makes me very happy to see 500 stable on a full conroe. :)

it seems the 5:6 ratio is definatly among the best ratios to OC with.

on a side note, 4 ghz stable on air with a E6600, goddamn I like that.
thats a CPU I wish I could play with.

update on Quad Core....

seems I've hit a snag.
one thats been driving me nuts for the last 2 days.

I can boot up nearly every time at 8 x 450 at 3.6 ghz easy... but I've only made it into windows once.
why is this driving me nuts?

cause the first time I tested quad core on this board, I was using air cooling, and I got it into windows at 3.6 ghz about 10 times, ran super pi, looked at temps and everything and it was all fine...
then I took it out, and ran it in my P5B Deluxe for the last few weeks...
then 2 days ago, put it back in this board... and now I can't seem to replicate the earlier success I had.
it's been driving me nuts...
the board will boot at 3.6 (8x450) everytime... but wont make it into windows any higher then 360 anymore...
why theres such a large gap between bootable speeds, and windows bootable speeds is whats been driving nuts...

especially since the first day I got this CPU, I was doing 3.6 ghz just fine on this board.... on air cooling....

why could I do it a month ago, on lesser cooling, but not today, with the same board and same CPU on better cooling??
and I spent hours trying to figure, what did I do differently the first time??
and I just can't get it to work again.

all I can do right now, is get it to boot at 450... not make it into windows.

AARRG!

Nice thread kunaak. This board is funny with dividers, and even funnier that high FSB & Ram speeds are slower - at least in every config I have tried. Here's the Beta Clockgen for this board :)

man, I feel dumb.
I helped franck get the CPUZ data working for the 680i by doing constant dumps and sending them for him.... and then asked about a clockgen way back in november, and we never really followed up on it.

should have figured he would have gotten one by now. :D

(took franck less then a day to get CPUZ working with the 680i, that guy always knows how to get things working first)

Kunaak I got a clockgen for ya here...tried a couple of times today and so far it seemse to work just fine. PM me or let me know and I´ll send it to you.

damn...

it doesnt work with the P5N32-E SLi...
gotta email franck.
too damn curious to be this close and still not have one working.

Well it works perfect here....as I said..let me know and I´ll send it to you.

Seems you hit about the same FSB wall I've been at all week long with my QX6700... I've tried about every combination of chipset and VTT voltages by now, and nothing seems to be getting me over 350 stable (orthos). I thought maybe it was my bios (running beta 702), but I guess not...

For me 9:10 divider is most stable yet. It's the closest to 1:1 as I can get stable, and I can get higher on FSB or RAM freq because crappy memory is holding me back; it's Geil 800 Ultra 4-4-4-12 rated at 2.1V, it can barely make rated timings and freq on rated volts, and on higher volts i gets incredibly hot (I burnt myself) and unstable. I guess they don't use D9s anymore.
Anyway thenks Kunaak, your hints helped me a lot.
I'll try to get more juice of this board as soon as I get better RAM sticks.

If you put your quadcore in after using conroe the board will disable 2 of the cores.

If you reset cmos the other 2 will come online. That could be why you were hitting that high fsb while others are still dieing around 350 or so.

anytime I change CPU's I clear the CMOS, plus, as far as I know... removing the CPU will clear the CMOS by default...

Hey Kunaak...just wanna thank you again for posting this thread. Voltage on the ram on the IN9 is proving be close to how you described. No need to crank it up till you absolutely have to.

Thanks again bud................

Not on the P5N32-E. Going from a E6600 to a Q6600, I couldn't figure out why it kept my exact settings but I only had 2 cores. It was weird I was the only one that had a 680i that did 450x8 while others couldn't even get 350, then I figured out that I only had 2 cores. Going to 4 cores I couldn't boot windows over 338 or so.

You seem to be experiencing the same thing.

well that theory is already blown.

this is after a few times clearing the CMOS.

so 450 is indeed possible on these with quad core.
the problem?

the videocard.

too much videocard power greatly reduces your stability.
I have 1000 watts of power here, but removing the 8800 GTX and putting in my 6200 TC. is what finally got me into windows....

450 with Qaud Core and 680i.

Curious as what the 12V rail is rated for in amps on your psu? I remember reading one of the mods stating in the thread about the 20 core cluster the quads need a really strong 12V rail.

I would also like to say that after reading your post my life as a 680i owner/overclocker has gotten much easier with the striker. If I couldn't get settings to post I would bump voltage and then again, only to give up and go for new settings, yet always wondering what I needed to get those settings to boot. Now I know that those settings/ratios the board just does not like and instead of playing the voltage game play the ratio game.

I remember your 3500LL's as my set which I am running right now got stronger with volts.

So what dividers are the strongest for you? I've gathered you really like 5:6 and it seems 10:13 w/ volts and 9:10.

I am playing with my striker right now and my board does not like 5:6. My board won't boot w/ FSB 400 and mem 480, but boots no problems with FSB 400 and mem 500, which is 4:5. Armed with this new information I think I can finally figure out how to push my memory.

Thanks Kunaak. :toast:

Also what amount of volts are you pushing through NB, SB, CPU VTT, etc to get 500FSB?

I have a 750 watt single rail PSU from PC Power and Cooling, the Silencer 750, that has 60 amps on a single 12 volt rail.
I have that PSU paired up with a 250 watt VGA PSU from Thermaltake, powering the videocard when I use the 8800 GTX.

NB = 1.6 volts.
SB = usually Auto.
CPU VTT = max always 1.55 volts.

Working fine here, I have the same board as you. I wonder if the DL link in that thread changed or something.

http://img.photobucket.com/albums/v31/canny/4ghz.jpg

already sent all my info to franck, did some info dumps and talked to him about the problem. hopefully he has some insight that helps find whats happening, and why 1052 doesnt work for me but does for others.

Also 6x and 7x 450 fsb is easy to do on Quadcore and 680i. When you say you are doing 450 fsb I thought it was higher than 6x or 7x. Try to get Cpu speed over 3.5 ghz with more than 360 fsb then you have accomplished something, otherwise you have just done what everyone else has... 479x 6 was my max fsb on this board with X3220. Still 360x9 was also the max with higher multiplier.

As you lower multiplier your FSB speed can increase with quadcore. Try setting multiplier to 11 or 12 and you won't be able to make it past 300-310. Same reason you see a lot of the quadcore 3d scores with 310x15 or so.

Version 1051 works fine here

all I can say then is show us.

cause so far I have yet to see anyone above about 350 besides me.

setting 7 x 450 is the limit of my cooling on air.
at 3.6 it boots at over 60C, so I cant do anything more then boot.

if you can get 480, show me.
I want to see how.

as for "set 11 or 12"...
your right.

it wont work.

my highest multiplier is 8...
seems you should know that since you have almost the same CPU. :rolleyes:

A couple of observations with QX6700 after testing many things that are talked about here (bios = 0702beta) :
- max fsb Orthos stable is 348Mhz no matter what I try
- dropping multiplier to 6 or 7 does not change FSB max at all (in my case)
- removing 8800GTX and going with PCI card did not change anything (in my case)
- max vcore I seem to be able to set is 1.36V real, if I set anything above that in bios it just reverts to 1.36V
- memory testing with quad core has been crap so far : I haven't been able to clock above 1100Mhz manually. The best I ever got was with my Dominator PC8888 modules : 1111Mhz cas 4 when I use the "SLI" setting. I have several sticks of memory that scales above 1200Mhz on P5B-deluxe but none so far here.

I hope all this changes when I move to Conroe tomorrow or the day after, but I'll stick with Bad Axe 2 or P5B-del for quad core, for now anyway. Maybe the GTL mod can do some good on these boards as well ?

wanna try something for me.

set your FSB to 1467 (366) and then set it to linked.
set the ram ratio to Auto.

your ram will wanna boot at 1.1 ghz...

but that might work.
thats been the highest stable overclock I been able to get from this CPU+Board so far.

Thanks :) I'll try that when I get home tonight and report back.

I just order a QX6700 B3 (ES) which I intend to use in either my striker or EVGA board...

--note I do run phase

Question: Are you guys saying that I will not be able to run 420x10?
Hmmm how about 350x12 any luck?

350x12, but you are talking about 320w of heat from your cpu. This may be too much for your phase to take.

How did you calc 320 watts? Just curious.

FYI: I maintain -32c running orthos at 4.4ghz (440x10) with my e6700 ES and 1.65 volts for 12 hours on my modded Jinu117 unit ...

I was hoping this would do the trick but well see.

Can anyone suggest a way to get a higher multi on the x6800 stable? I'm currently running at 12x dead stable (just under 3.2) and would like to up it to 13x (whats the point of an unlocked multi fi you don't use it?). My temps are mid to low 40's max currently so I doubt another multi bump would be outside my cooling potential.

When I have tried it the system crashes or reboots on start up. Thus far all settings in bios at stock.

I would be fine with 3.5 or thereabouts (the multi will up it to 3.458 Ghz) Up the FSB a few points and 3.5 should be easy.

Any advice would be appreciated.

Thanks

I guess you need more than 1.3V vcore to go any higher ;)


Does anyone have trouble tuning the vcore like me ? I thought it was a quad core issue but it seems it isn't.

On E6700 (ES step 5) / bios 0702beta :
- If I go for stock vcore I get around 1.26-1.28, confirmed by Multimeter (normal values I'd say)
- If I go a little higher, but less than 1.35V, I get 1.36V vcore (multimeter confirmed) :confused:
- if I go above 1.35V, I get 1.44V-1.46V (multimeter confirmed as well)vcore :confused: :confused: :confused:

I went all up to 1.5V but it stayed at 1.46V. I didn't go higher as I'm still on quite lowly air cooling, will try later on phase.

What is going on here ? Thoughts or ideas anyone ?

up the 1.2VHT to 1.5 or higher.
up the NBv to 1.7 or higher.

that might do the trick.

Robilar, its been awhile since we have talked at OCN...

If you want a step by step send me a PM and ill walk you through it. Both Wax and I have had very solid luck with the x6800 and the 680i chipset...

You know where to reach me ;)

Hi!

Got p5n32-e SLi rev A2 board with 0602bios few days ago.
First look was nice to see that vCore voltage problems are gone.
With 0602 Bios (was already intalled) if i set voltage to 1.5 i got 1,47 what was pretty good.Vcore voltage goes up to 1,9V. Probably 1,85 real, wich is more than enought.
memory on my board is little overvolted. with 2,3V in bios i get 2,35 in reality.
Board works like a charm, no problem what soever.
Running Celeron D 347 @4600mhz with 1,55V (1,52) with stock cooler.Cant go higher because CPU gets too hot.
Waiting quadcore to go cheaper. :rolleyes:
Yesterday installed 0702 bios but see no differene. Working just fine.
passive cooling on motherboard is cool enought with my Celeron D. No need to put extra fan on it yet.
D9DQW Fatbodys are working like miracle on this board.
Running 2gb Dualchannel @800mhz 4-3-3-7 1T with only 2,2V!
Havent tried 2T yet. Probably will do 1200-1300 easy.
Priice of this board is also much cheaper now. i got it 260$ in europe.
Nice board!:banana3:

With BIOS 0702 max real vcore is 1,55V no matter what voltage you set in BIOS. Using a X6800...

P5N32-E SLI Rev.2?? or do you mean the "Plus"? i didnt know there was a Rev.2 for this board.. =S

with respect to your keen observations;

424x8 = 480x7 as far as ram bandwidth and cpu scores go.

My ram doesnt seem to respect dividers...just speed and timings and command rate.

i cant git past 480 fsb...had nb set at 1.75!! no deal shameel; anyway super high fsb means much more to people who have super high cpu clocks like 4gig+...like over 9000 mb/s: wow.

tried 5:6 and 9:11...no problems at all; but i've tried heaps of dividers and they all seem to work...
my ram responds exactly the same regardless of dividers.

After some testing I get the following vcore results with 0702beta bios :

- when the motherboard is in auto, standard, AINOS or AIclock mode, vcore adjustments are normal, so if you set 1.6V, you get 1.55 real. That's quite some droop, but anyway, it works.

- when you put the motherboard on manual clocking up to 300FSB all is fine : vcore adjustments follow bios

- anything above 300FSB is completely messed up. You can set whatever you like, the board decides different, and I can't get over 1.36V real now.

I'll try some other settings in bios next, and then switch to an earlier bios in the hope it gets better.

looks like what my Plus did

fsb < 300 , Vcore can normal adjust
fsb : 300 --> 400 : no matter what Vcore is set , It will always be 1.425v
fsb > 400 : Vcore always be 1.525v

I guess non-Plus and Plus ver. do need serious Bios update for Vcore !!!

Anyone have tried eva2000's voltage pin mod? How do voltages behave then?

Bios 0302 lets me change vcore (but you can't see it in bios or Asus Tool). I can measure the changes though.

Bios 0302 is the only bios so far that they havent totally screwed up.
each bios just gets a new set of bugs.

sometimes the NB voltage past 1.6 volts fails the board to boot ever again.
sometimes you have no control over the Vcore anymore.
sometimes you have a incredibly low Vcore.... set 1.9 volts to get 1.76 volts.

so far, the bios with the least amount of problems for me, is 0302.
0602 is ok though.
atleast I can fool it to boot at Vcore voltages I need, in that bios and all the other voltages act normal.

Thanks for this info kunaak:)

Yes 680i kan give a lot off headache.

I will test some more,now my system is stable.

What you say abought 8800gtx take power,
i find true.
It was easyer to oc when a had my xfx7800.

I use 0302 the only bios that i feel give my control.

Look at this thread for evga think they will come
with some solution abought 680i and quad fbs.
There board has more problem with max around 300 fbs for quad.

Sdumper nice score.
Rising multiper is no problem on quad if you have god cooling.

I been folllow the quad and fsb problem for a long time now.

Yoxxy: 479x 6 on a quad is almost to good to be true.
I dont say that is not true,but i have never seen someone
with that high fsb on quad(680i)

Here is the thread by shamino.
http://forums.vr-zone.com/showthread.php?t=112265

Hope someone will test the plus version of this board with quad.
I dont think asus have fix the GTL Reference Voltage for plus.

Evga is working on this here what JacobF wrote.
Quote:
No the P25 was not intended to the be the fix! We still need to completely test 100% the fix that we do have for Kentsfield and close to 400MHz FSB's, early results are very promising. I'm sorry that I do not have more details at this time.

Have seen a volt mod for GTL Reference Voltage think it was for the bad axe.
Dont rember where i did see it.

Think evga is coming with some solutions with bios
I am waiting for that.
If asus now abought this or if they are going to do something abought it i dont now.
Asus support is not the best,when it come to OC.

If anyone have some more uppdate abought quad and fsb.
I'`ll bee happy.

Hey Thorgal,

Are these beta bioses for the P5N32-E SLI?

If so, anyword as to when they'll be up on the FTP site? =D

Look at the compiling date : only yesterday ;)

So yes, they are most certainly beta updates... and I don't think they are ready yet to release them, as I can now indeed confirm that nothing has changed for vcore issues.

From 300FSB upwards, 1.36V is the max. vcore I get :( Now I'm testing for max fsb on lower multi's.

With QX6700 I'll try and test later tonight, but my guess is nothing much has changed. Max multi I could set with my quad was 13, on 14 it wouldn't boot. Combine that with a max fsb of about 300 (otherwise you can't get decent vcore), and even 300x13 wouldn't boot here. So the options are limited at the moment. Others seem to have more luck and get up to 15 multi on quads, so your mileage may vary.

10.Fixed CPR fail if overclock too much.

This at least looks promising.

Put the 0803 beta bios on my webspace for a day or two, find it here

Bios does nothing new for me, but might for you. I found it to be quite safe, you use it at your own risc of course.

I guess I have here one of the "worse" 680i boards, as OC'ing on this board is about the worst experience I ever had. I can't even surpass 350FSB any more with E6700 (any multi), and vcore is limited to 1.36V above 300FSB.

I don't want to hijack your thread Kunaak, so if I have to start a new one, just say so ;)

ASUS FTP now has the 0802 bios; it's not yet on the download site =)

Thanks alot for this post! :)
If it wasen't for you kunaak i would never have tried:
2.35vdimm 5-5-5-15@1200 mhz med 5:6 divider (unlinked)
Fsb 1600(400)=3.6ghz@1.38vcore
1.2VHT = 1.62v
SB core = 1.70v
CPU VTT=1.62v
DDR2 TERM=1.18v
NB CORE=1.76v

And i was actually able to boot my 26B E6600 at 3.6 ghz, now i'll try to get it stable for 10 hours in orthos.

On the Quad side of things:

I've been fighting with a Q6600, 4GB Corsair XMS PC6400C4, and at first a P5B Dlx and now a P5N32-E. I've run the memory at DDR2-900 for hours in Memtest, no problem. I couldn't get either board P95 stable over 320mhz though. I don't know if it's in the proc or what, but I'm going nuts. The other problem is I've gotta use 64-bit Windows for this customer, and I think opening up the extra registers lowers my clocking.

I'm going to go back over this thread when I get back to work on it later, and see if I can make any headway. I'd love to see a 400+ FSB and 3.2ghz, that's what I've wanted all along for this customer. It's a pain when I've almost got my e6300 100% OC'd, and I can't budge this Q6600 :brick:

Are there still troubles with Q6600?
...i mean with the last bios's...
I use 0903 coz it is the best one for my board...it looks like there is FSB Hole 400-425 and 50&#37; stability on 412,5 :) ... :(, right at the strap.
is there any possibility to be quit this FSB Hole with newer bios's?

Those are insane voltages mate, I don't hink your board will live long unless you have amasing cooling on the chipsets and PWM area

man, are you mad? :)...theese voltages are for QCore 400+ overclock! :)
1.2VHT = 1.55V
SB core = 1.55v
CPU VTT=1.62v (enought, but only if you want to hit 500+)
NB CORE=1.46v

Thanks very much for taking the time to put this post together.

The new bios 1201 has moved strap from 1699-1700 to 1799-1800!, or from 425 to 450mhz!

thanks very informative post, still waiting on my new rig to arrive at the door :)
