Ah I see, I wasn't aware that with the Quad CPUs you could lower the multiplier but not increase it, I thought one could simply not change it all. Good idea, although I've already got my Kingston HyperX DDR3 1625 modules! I don't think Kingston will let me return them, outside the 30 day window.Quote:

also does anywhere know where theres a post/review explaining the rampage various bios settings,, thanks
they "pull-in" the phases. :p:
essentially, they tighten the performance level for whichever phase you adjust
ie. i have set a PL of 8, but the channel A phase's, 2 and 5 have been "pulled-in" to level 7
cheers pyro appreciated :), i have the rampage coming tomorrow but already have maximus extreme and the rampage has a lot more bios settings so a bit of a learning curve

hope it treats you well m8 :up:
i moved to the RE after killing my old p5e3 prem. and i deffo think this one feels like a more solid, stronger board
[edit]
hi cheapseats
yup, i'm running the cellshock and crucial kits in my sig
i've had no problems with POST'ing with these kits since setting skews
before i set the skews, sometimes the kit would lock up in windows, and sometimes i would not be able to POST, let alone get into windows
if i were to change the memory speeds/fsb, the skews would likely need adjusting again.
:shrug: s'all just trial n error and diff kits seem to like diff skews :shrug:
Interesting Pyr0, cheers. Had success here with NB and DRAM skews before with 2x1Gb, but 4x1 was just for fun really.
Using CTL skews I got 86+ stability at 792mhz (but CL8 only) for mine as 4x1GB. so I wasn't that motivated to carry on....:D
WoW nice ... ;) KensekQuote:

i guess thats why this mobo is very fussy about overvolting ure vdimm.
also this is really a good mobo to clock stablely...
its hard and has a lot of options
this would make the transition to i7 easier
one thing though..
nobody has posted linpack stable 2000mhz 2x1gb .. atleast 50 runs around 50 mins..
even for i7...
u'd be surprise on ure gtl's setting how wrong it is..

Hi MnM, you're right :) Performance Level = tRD (= memory controller Read Delay).Quote:

Lowest (allowable) tRD will give best performance, but Clocktwister seems to have diminishing returns beyond Lighter > Moderate.
I've done some more tests to compare Everest results between different Strap/ClockTwister/tRD combinations. Sorting screenshots and will post later.

interesting stuff... this mobo..
learning a new thing everyday
also been doing this for 2 sticks only
use test 5 without any skewing to determine vNB and vdimm.. run it in loops a few times more than 2
and then restart from default test 0 to confirm test 5...
then only do the stuff above..
memtest86 doesnt prove as a good initial test for 4x1gb... usually use test 5 but it will only show the vnb /vdimm thats accurate for 2 dimms only..
the test above will determine the rest and then only rerun memtest86 a few loops
this solves the weird errors u will get later with test 7/8
two most nb dram vtt and dram vtt A/B that i have been using is
1. nb dram vtt - -5 dram vTT A/B 12.5
2. nb dram vtt - 12.5 dram vTT A/B 25
interesting stuff..

ure cpu skew/nb skew shows promise + the dram vtt ...
oh yeah even had some weird results with sb 1.1v
but that one still inconclusive..
again a crazy board..
I've tested and thought some more on the 200 strap....
The main issue with tRD and cL combinations in certain FSB ranges, is non-allowable combinations for POST, resulting from MCH minimum timing limitations.
Earlier tests showed that the 200 strap allowed a lower tRD value to be used for a given CL etc, compared to what 266 and 333 straps would allow for POST.
eg: 200 strap allows POST/stability with CL7/tRD5, but 266 and 333 straps only allow minimum tRD6 with CL7.
Regardless of whether it works for DDR3, the existing (DDR2) tRD equation doesn't include a discrete reference to the Strap in use (other than including the divider in use). There would seem no allowance in the equation to predict the differences in POST behaviour, when using 1:2 divider on different straps.
Yet on this board there are differences in Strap/tRD POST allowability, which also seem independent of FSB (in 400-500FSB range I tested).
Despite the 200 strap allowing lower tRD values to POST, I would guess that the minimum allowable MCH timing (for POST) may not actually be lower on the 200 strap.
If lower allowable MCH latency resulted from using the 200 strap, then 200strap/CL8/tRD6 would be faster than 266 or 333 strap with CL8/tRD7.
Instead (I suspect), some other latency is introduced/forced by the 200 strap, which even with a lower tRD value, does not fall below the net minimum time for allowable POST.
If it's something along those lines, a forced increase in overall MCH latency (as suspected of the 200 strap) may allow POST/stability with lower tRD value (than 266 and 333 straps allow), but may not actually be better than neutral in terms of net MCH 'bandwidth' and/or stability, compared to other 'tighter' straps with higher minimum allowable tRD.
According to Everest, the 200 strap as tested gives lower performance, tRD for tRD, than 266 or 333 straps, with similar low performance apparent on the 400 strap too.
This doesn't mean that the 200 strap isn't worth using - it may be more stable - just that any expected benefit of allowing lower tRD values, may not come with it.
slowly piecing it together I hope, but just from incomplete information/knowledge :)

A big thanks Cheapseats for the informative posts :up:
I had no idea the staps had that effect on performance. I'll try some different combos on mine later.
Does anyone know if the Zalman 9500 LED will fit on this board? I've had a difficult time trying to research if it will or not:
http://zalman.co.kr/DataFile/product...0ALED_m(0).jpg
Also, as a measure to reduce the weight hanging off my board, I'm considering changing my Noctua U12P for a Noctua U9B, it's a whole 200 grams lighter and yes the cooling performance isn't as good, but I'm thinking of upgrading the fan to something slightly faster.
U12P on the left, U9B on the right:

I did some tests with 400x10 1600 and I can confirm that with 1600 CAS7 tRD 5 give the same performance as 1600 CAS6 tRD6 but with lower DIMMv and NBv , quite awesome I think.

Not much of a different, conclusion, using strap 200 at 1600 777 21 make it possible to use tRD5 with low DIMMv and NBv.
Lower the tRD, 1600 666 18 tRD4 Strong Strap 200 DIMMv ~2,00 NBv ~1,70

Back to Strap 333, 1600 666 tRD5 Strong Strap 333 DIMMv ~2,00 NBv ~1,70
http://i282.photobucket.com/albums/k...RD5StrongS.png
Not much of a different in bandwidth but in latency and with much higher DIMMv and NBv.
And once again, using strap 200 at 1600 777 21 make it possible to use tRD5 with low DIMMv and NBv and it gives a pretty good performance, quite awesome in my opinion.

Absolutely, because the width of the U12P was hitting my U6 Northbridge heatsink, the U9 is significantly narrower, they would both definitely fit. Good point. It's just I was adding up the "extras" being put on this board:Quote:

That's over 1kg of metal hanging off the board. I need to ways to reduce the weight and think the U9 will be perfect, although coupled with a higher CFM fan.
How did your Zalman 9500 perform? I'm considering one of these instead of the Noctua U12P, mainly due to its reduced weight. I also see the Xigmatek S-1283 is around 600g with fan.
The Zalman is something I would consider, except it hangs off the top part of the board. On the compatibility chart they specifically ask users to make sure there is a gap between the top of the board and the power supply.
This was in the early days of my RE ownership. I was struggling to get more than 420FSB and getting very frustrated at my OCZ memory not running at its rated speed so I went for the TRUE120 for a no compromise CPU cooler. From memory the Zalman ran 10 degrees hotter under load. The TRUE120 is HUGE and I had to remove a side fan from my case at the time which was a C/M Stacker 832 to fit it inside. Of course there were other issues, early bios, the huge number of bios options and N/B temps that also hampered me. When I moved to water I found the board to have warped 3-4mm when sat in its free state on the table although when fitted in my new case it 'bolted up' flat and there are no long term ill effects. Of course I never measured the mobo flatness when it was new so it may not have been perfect then and may not have warped at all - how is your new board ?.Quote:

This combination is just over 200g lighter than keeping the Noctua U12P. I already returned the Noctua U6 but can get my hands on a HR-05 IFX instead.
If you are reduced weight you should consider these from Enzotech for your SB.
http://www.enzotechnology.com/images/slf_1.jpg
http://www.enzotechnology.com/images/cnb_s1l.jpg
I´m using CNB-S1L for my SB and the temp is ~40C
Hi Aln688, looks like a great CPU & NB combo :up:
Have to agree with Ghostleader that the Thermalright HR-05 SLI/IFX is a bit OTT if it's not too late and you have it already. I have the CNB-SL1 which maxes out at 53 degrees, the SLF-1 should arrive tomorrow which should reduce that to ~40.
So you both think the Enzotech CNB-S1L is a better choice? Actually I still have the Enzotech CNB-S1L I just wasn't planning on using it. I was just put off putting the heatsink on at an angle, but I suspect it covers the entire SB chip.
I was going through the numbers again of using the Noctua U9B -vs- the Noctua U12P, after adding up the weight of the fans as well, I'm only saving just over 100g using the U9B. If I take on your suggestion of the CNB-S1L I'm sure I'll save a bit more as well.
The calculations look like this:
Using Noctua U12P:
--> SB heatsink, Thermalright HR-05 SLI/IFX (125g)
--> NB heatsink, Thermalright HR-05 SLI/IFX (125g)
--> NB heatsink fan, Sanyo Denki 80x15mm (68g)
--> CPU heatsink + fan (760g)
--> Total : 1078g
Using Noctua U9B:
--> SB heatsink, Thermalright HR-05 SLI/IFX (125g)
--> NB heatsink, Thermalright HR-05 SLI/IFX (125g)
--> NB heatsink fan, Sanyo Denki 80x25mm (110g)
--> CPU heatsink (460g)
--> CPU fan, Sanyo Denki 92x25mm (150g)
--> Total: 970g
If I use the Enzotech CNB-S1L, it is only 50g, saving 75g in both cases. I'm weighing up still using the U12P, if the difference was a few hundred g's then the U9B would be a definite choice but it's only just over 100g difference.
Don't know if you noticed, but Enzotech is bringing out a new heatsink, the MOS-C10, three of these would fit the chokes near the NB perfectly:
http://www.enzotechnology.com/mos_c10.htm
http://www.enzotechnology.com/images/mos_c10.jpg
Thanks for the information, to be honest I wasn't sure how much heat the SB pumps out. I suspected it was a low heat component but read a few forums where people experienced heatsinks on their SB that they couldn't touch with a finger due to it being too hot.Quote:

My board minus Asus's heatpipe assembly is very slightly bowed, with both sides pointing up and the middle down, but it's very slight. So far my board hasn't had a CPU heatsink installed on it, so it's more or less bare as from the box. Thanks for the links, very useful to review.Quote:

I'm guessing regarding the problem, I tried going to Zalman's web-site for motherboard compatibility, useless, it was last updated August 2005!
all those with quaddies stable on rampage extreme..
can u guys post ure IBT/LINpack for 2x1gb around 15 runs..

and ure core gtl..
curious.
Well the combo might be good, but after studying my new HR-05 SLI/IFX, I've came to the conclusion the quality seems good, but the great idea got lost somehow in putting the package together. The fan clip the way its designed means the fan sits on the back of the heatsink, I don't know if this is a good idea as it means the heatsink further sticks out and coming near to hitting the video card, it would be better to have been positioned inside the heatsink, hovering above the chip it's used on.Quote:

Looking online here at some reviews, it seems the pushpins aren't used at all, only the screws method where the screws come up from under the board, the clip goes over the heatsink and the thumb screws screw down the heatsink, one item I wonder about is, how much are you supposed to tighten the screws? I don't want to over tighten it, do I tighten it until the heatsink won't move?
One other item, the Enzotech CNB-S1L, while a nice heatsink, does not properly fit the Rampage Extreme's SB chip. Sure, I could angle the black push pins inwards then they'll push through, but I refuse to angle a pushpins just to get it to fit, there's the potential for the pushpins to come undone. Not much choice for SB heatsink in my case. This link contains a picture that proves the point, 3rd picture down:

another interesting discovery
the gtl for NB adding it only makes things worst
e8600 and team xtreem pc3-15000 2x1gb and 4gb
on 4ghz 500x8 1600 CL7 1T tRD 8 dram read/write disable
cpu vcore 1.1875v
vtt/sb/nb/pll/dram - 1.12/1.5/ 1.249/1.5/1.8
cpu gtl 0 +40
nb gtl +30
dram A/B vtt +25.
ibt test pass 30 runs so around 2 hours
if add nb dram vtt +12.5 hangs on 4th
up multi to 8.5 and vcore to 1.2875
hang on start or ibt.
cpu clock skew to delay 200... pass 30...
so higher vcore/speeds require cpu clocks skew adjustment...
cant test 4.5ghz on ibt.. has it exceeds my cooling ability cause 4.25ghz on load is already 66C.
but testest with orthos priority 10 with blend then custom and max fft at 8 to stress ram/nb/cpu.
shows similar results...
but so far IBT has proven that nb gtl doesnt need any increment and for dual cores only gtl 0 needs a increment of +40. to make the gtl to 0.67.
the gtl results of this board is exactly same as maximus 2 formula
so hence y i am asking all those posting results to show ibt...results...
the cause of the hanging issue was the dram vtt channel A/B.. can be proven with extended runs in memtest86
wrong pll voltages will hinder ure results in memtest86 and showing long runs of stable system but in IBT failure is imminent.
also another interesting result
memtest86 test 5 shows that certain strap/trd prefers a certain clock twister.
sometimes higher and sometimes lower.
the current difficulty is getting 2x1gb 2000mhz tRD 8 gtl's correct.. so far IBt can run 50 runs without failure
but all the residuals are varying...
cheapseat.. i think this was ure issue when u tried to go more than 2 hours on prime/orthos blend..
micron d9jnl's should be able to do 2000 8-8-8-24 110 2x1gb clock twister strong strap 400 vnb 1.6 dram vtt a/b +25 at 1.9v only...
so cellshock 1866 / team xtreem 1866 owners .. heheh nice stuff..
hope somebody can help with this and show posting of ibt results...
for 4x1gb
so far for booting at 2000mhz
setting skew adjustment as cheapseat did but on all channels shows booting but will fail memtest 3/5
The S1L has 2 fittings 54.6mm and 59mm, not sure exactly what the RE hole spacings are but all you need to do is to file the overlapping holes into a single slot and position it centrally over the S/B chip.Quote:

not minus..
u can see from IBT - Intel Burn Test.. .that ure gtl is stabalizing.
since ure using a e8600 which is the proc that i have bought/given/tested the most amount in my entire 27 years of living in this planet.
most e8600 that i have tested has one thing in common
the stock vcore at 3.33ghz at whatever vid is the 4ghz vcore
example mine is set 1.1875 is the stock vcore..which runs 4ghz
and then try 1.12v vtt which is good up to 500 fsb
nb 1.25
strap 333
1600 CL6 at 1.8v
and try ure gtl's using linpack
for 2x1gb i advice 50 runs
for 4gb kits advice 15 runs
both will be around 1 hour.
make sure u have sufficient cooling
e8600's also has one more thing in common
say 4ghz is stock at example mine at 1.1875
then the 4.25ghz is at 1.2875
and 4.5 ghz is around 1.4v for asus mobo cause they is a bigger droop after 1.35v.
but for ddr2 up to 4.25ghz not much setting to change other than vcore
but ddr3.. ure rams will start acting up..
so need to change cpu skews..
and ghost a lot of ppl are quoting stable etc
its given..
i can run ibt for 2000mhz CL8 for 50 runs that shows vcore stable and nb /cpu gtl and even pass memtest etc.
but all the residuals are different. and theres a few common pairs popping up..
this is y i think some ppl are failing to run the full orthos etc...
and it will fail my test 3 that i posted using orthos a few pages back..
also those having a maximus 2 formula board and some ddr2 rams .. u can confirm this findings on cpu gtl and vcore and vtt
its exactly the same.
also the use of pll for dual core..
advice not needed until u have weird results .. example start can run ibt for full run
restart it cannot and hang etc...
it always messes up memtest86 results for vdimm for test 5
tested without dram vtt.. and pll.. memtest86 hang in 45 minutes
with pll it passes to 1 hour 30 minues but fails suddenly in test 5 which is mainly nb/dram voltage and tRFC settings.
reduce pll and increase dram vtt to +25 for both A/B.. passed 4 hours.. no hitch and i stopped it.
lastly to answer that question
for p45
it favours gtl 64 for nb and cpu up to a certain vcore
but i see on high vcore and high speeds gtl 67 is still the best for core and nb.
oh yeah and another thing i want to clear about e8600's
i had a vid many vids and many different stock vcores
one thing i noted
whatever the voltages were
the stock vcore = 4ghz temp for all of them were the same
and the +0.1v for 4.25ghz temp for all of them were the same
when i ran IBT with the same cooler
the difference was the tweaking of the gtl/skews and sometimes rams... which depended on that vcore and speed.
i guess thats y a lot of those 600+fsb clocks seems to do well on the high vid rather than the low vid.
oh yeah and disable legacy support..
oh yeah remember the nb+30 thing is still inconclusive.
but i think i am almost got it for this board on what voltages are insufficient and what test to confirm it..
need to run more test..and make sure its not ram chipset dependent.
It's a nightmare. My Q9550/2x2GB G.Skill 1600 is able to make 200+ IBT @ 425 FSB/PL6/AI C.T. Stronger, with GTLref all 4 in Auto and NBGtlref=+20 (VERY IMPORTANT). But if the system hangs and reboot in the #201 IBT (i.e. because of some instability occurs in pcie -yes!-), then the internal management of the GTLrefs become crazy and then the system is unable to make #1 only IBT with the same settings.Quote:

the nb gtl .. also is a issue
it can stabilize fsb
as pll voltage can do the same...
but which one is better.
so far seems to be pll..
so guess nb voltage for now can leave on auto..
Mmmm...Ok...i´ll try with the PLL. So far, my tricks for FSB stability are NB GTL and PCI-e @ 105.Quote:

This board has a lot more tweaks then I have ever had before so I think it´s gonna take some time to figure it out.
What about run LinX, isn´t that almost the same as Linpack or IBT?
For the moment I focus at 450 9,5 4275 Strap 333 1800 777 21 1N tRD6 Strong tRFC88 to get it stable with so low volt set as possible and trying to get 475 9 4275 strap 333 1900 777 21 1N tRD6 Strong tRFC88 stable.
So im going to keep it here for a while decent Pi time for the speed im working on another project was thinking liquid cooling and keep it at 4.8 ish maybe ill do some air 4.5 with 2000mhz ram since this cpu needs literally nothing for vcore 4.4 at 1.23 is sick In my opinion but shooting for more phase change may be around the corner and ill have it running 5ghz or something for 24/7 and ram will settle in at 1800 or so since I know it wont do over 2000.

found one silly test for dram nb vtt
kekek ure guys going to laugh
run orthos priority 10..
keep doing start / stop / start stop..
***56K warning.. *** if ure gtl not right.. high chance of shutdown and wipeout ure bios including ure profile... ...
so change now to must add dram nb vtt to +12.5
also with the both dram vtt at +25mv
this going to sound even more hilarious
good way to spot insufficient vdimm for the paticular cpu speed.
getting ready for tomorrows 3mark benching session with 9800gx2, pretty good E8600 and of course rampage extreme.. :D the pic it self it pretty explanatory..just took the heatsink out and bolted 2 D-tek fuzion blocks to the card
http://i163.photobucket.com/albums/t...s/DSCN1419.jpg
dont know if this is a know issue or wat... lets say after a superpi 32m i reboot and try to go in to bios, sometime when i hit delete, it will give me no display which i assume its hang, sometime it wont happen...i even get this with all settings to default.... wonder if anyone has the same problem or not....
rob2k and Ghostleader, cheers guys. It'll be interesting to see what people can do with the 200 strap.
Ghostleader, thanks for the 400FSB results - I didn't test for lower voltages on 200 V 333, but with the same max performance across 200/333 straps (though not possible with all FSB/CL), lower voltage looks like a nice bonus on 200 :up:
rob2K, the 200 strap will be slower (same as 400 strap) for FSBs around 475 and CL7. To equal 266 or 333/CL7/tRD6 performance, you need to run CL7/tRD5 on 200.
As far as tested, CL7/tRD5 on 200strap becomes non-allowable at some point between 401 and 450FSB. You may have found a no-POST already with the 200 strap, but 266 or 333 with CL7/tRD6 are both faster than 200 (and 400) with same nominal CL7/tRD6.
many interesting points cstkl1 - it's hard to keep up with your speed on this :DQuote:

DDRrefs made a good difference, but only with negative A/B DDRref for me.
I was using Custom>2048-4096k to test for NB + A/B refs and found best results with NBDDRref +12.5 and both A/B DDRref -10.0
Differences of only +/- 2.5mV for A/B DDRrefs gave me +/- 2 hours for Blend, and I think other 'working' values would vary with other vDIMM etc. Seemed like a very narrow margin for success. Positive A/B refs gave me blue screen or no Windows.
With same other settings, +12.5/-10.0 combination was (repeatably) 7-8 Hour Orthos stable, and the next best (NB+12.5/AB-12.5) would only last 4 Hours Blend then fail on a Large FFT.
Pretty frustrating - and with low memory performance too.
For my settings, positive NB GTL fails quicker in Large FFT than using negative value. In 86+, I can 'remove' GTL related Test 5 errors by using NB -40 to -60mV range, but no Windows start.
Memtest HCI passed 2000% for same 500/1:2 clocks with NB and A/B DDRrefs on AUTO and lower vNB (1.56V set), so Orthos (over 2048k FFT) was more effective to show these instabilities.
Similar to vega22, I experienced problems with PCI-e and/or graphics card at certain FSB. At 500FSB, I find more predictable stability with 103 pcie bus and card overclocked or underclocked (stock is 580/1500/900). Time for a new card anyway ?
Have a cheap ;) new 2x1 kit today but should still be able to test for some new 500/1:2/CL8 results. Looking for decent CL7 clocks first though.
You need to file between both holes to create a larger hole? I was going to say because as is the peg moved to the inner positions will only go in at an angle, the pushpin won't go into the board vertically straight. Do you have a picture of your CNB-S1L as filed? I'd just be interested to see the result. Thanks again.Quote:

using a few orthos custom and silly tricks and ibt...
so now trying to understand whether skews can fix this or not.
setting the cpu delay to around 200 shows there is other ways to fix this.
but still inconculsive
weird other ddr3 boards was not at fussy but other ddr3 boards cant do 10500 on everest read for 400fsb at 1.25vnb.
but for 4x1gb i think will just give up
this board at 500fsb 1600 CL7 is already damn fast at only clock skew moderate vnb 1.25v is just a bit slower than 2000mhz CL8 trd 7 clock skew
strong vnb 1.6. still cant understand this part.. cause in normally u expect the difference to be big .
I want to ask something here to. I'm currently using on Rampage Formula (flashed P5E X48) vNB 1.51v and 0.63 NB GTLREF. I know, that by the CPU the VTTxGTLREF must be less than 1.0 (so, the Vref must be less than 1.0). So, what is it about the NB Vref. I'm asking, because my stability depends on NB Vref. So, even for benching i have to use vNBxNBGTLREF>1.0 Is there any problem NB Vref to be more than 1.0?
yo :PQuote:

read the previous post bro..
mentioned about the dram vtt as one of the causes of the hanging issue
one thing
i definately dont think u need that much vnb to run 2000mhz CL8
reason is this
at 500 fsb
strap 333 /moderate 1600 CL7 1T is giving performance around read 11200 for everest at 1.25vnb vdimm 1.77 tRD 8
strap 400/strong 2000mhz CL8 1T is giving performance around read 11600 for
everest at 1.6vnb vdimm 1.9 tRD 7
just doesnt make sense.. so something else must be the problem that i am
upping the vnb to compensate since write and copy performance is the same.
also noted was the gain i get from 1866 1.8v going up to 2000mhz 1.9v both at CL8 tRD 7..
the gain is disappointing for read .
PLL definitely did not help me.
So far, only i reach solid stability @425 Fsb/1701mhz by the +20 NBGtlref trick and slowing performance to PL7, AI C. T. Strong. It´s important too the trick SB +1.5V = PLL, both at 1.52 in my case.
EDIT: strap 333
As you just read, i´m too in q9550/G.skill and my stability too depends on NBGtlref. Very interesting.Quote:

damn so close to 6.2 ghz.. i defineatly need some more bruter power than my cascade :D
http://i163.photobucket.com/albums/t...uperpi7500.jpg
Hi Solarfall, GG there for cascade cooling ;)
I own a RE and the same E8600 cpu batch as you and I was wondering of your max fsb?
Also I'm actually testing the 0801 BIOS version and previously the 0701. Do you think I should test the one you played with here ?
I tested the 0401 and dispite the good feed it has, I can't boot OCing with it :( Setup is straight back to default at reboot :ROTF:
So far I think I am cpu limited for the fsb :(
My goal is to get rocking setup for Super Pi 32mo btw.
Any help would be great :)
'wish you get some ln² asap ;)
ToyTen
well i've tested all the publically available bioses and found that the one im using now works best for me.. about the max fsb im not too sure cos i just got it but i hear that the previous owner was able to bench it with +6.4ghz clocks soo that would be 640+ fsb.. this particular patch of E8600 scales well with high volts and cold temps (so i've heard and is seems to be true too)..Quote:

thx ;)
maybe you could drop the nb volts to 1.7v and bring up the fsb voltage to around 1.6v thats what i usually have those 2 voltage settings at.. i also have the load line calibration option enabled it helps to keep the vdroop in check when your stressing your cpu :yepp:Quote:

Thank you cstkl1, I'm not trying i get it more stable than the time of a Super pi 32mo here, stability absolutely can't be found at such voltages for every day use, it would damage it too fast i guess.
the point was to complete it at the moment:
http://images1.hiboox.com/images/480...03bed3827f.jpg
fsb630 PL9 was the goal. Now I can prepare the rig for ln2 benching. It might probably go higher in fsb, I hope so.
I actually need 1.501vFSB / 1.79 vNB / 2.26vDDR to acheive this, there's no way I can keep it for everyday use.
hey ToyTen .. what ram sticks do you have??

Can't wait to test it deeper under ln2 in early January. On this mobo i might improve it

Hi Aln688, how's it going ?. I had to file between the holes first to get my round file in and then at the inner most hole by about a 1mm at each end to reduce the hole spacing ......Quote:

Add small washers to prevent the spring going in the hole making the clamping forces uneven.
CNB-S1L = 53 degrees : SLF-1 = 44 degrees (on mid fan speed setting CHA FAN2)
some one know vmem read for this?
you might find the reading point searching all arround the condo's and more generally arrount the DIMM's. If I do find it I'll come back and tell :)Quote:

I've looked around online and there really aren't any SB heatsinks that will fit this board, it's no surprise people are turning to this option. I have an HR-05 SLI/IFX in my computer parts box, I'm just reluctant to use it as it seems OTT. One item I do wonder about is the RPM on that SLF, does it sound loud? I have a slow speed 80x15mm 2000 RPM fan I could use on my HR-05 SLI/IFX, just toying with the different options, but your board with your SLF and modification looks great. Cheers.Quote:

You could always set it to between 50-100% speed using the duty setting on one of the 3 optional fan headers for more control. I would recommend this without hesitation or the CNB-S1L if not trying to max out your system - I have to run my S/B at 1.6v.
Another strap-performance update guys - minor but useful maybe:
Read and Latency performance at 500FSB/CL8/1:2 (CT Strong)
As posted before, at 475FSB, 200strap/tRD6 and 333strap/tRD7 give equal Read and Latency with CL8, but 400/tRD7 Read and Copy are lower / Latency higher.
Unlike 200 strap at certain CL/FSB, the 400 strap does not allow lower tRD than 333 strap.
200 strap still allows CL8/tRD6 at 500FSB/1:2
Unlike results at 475FSB, CL8/tRD6 at 500FSB gives higher Read than 333 strap/CL8/tRD7. 400strap/tRD7 still has lowest Read and Copy / highest Latency.
Allowing CL8/tRD6, the 200 strap is able to give Read performance more comparable with 475FSB/CL7/tRD6 on 266 or 333 straps (EDIT: for same CPU clock).
The 500FSB/200 strap advantage is not available with CL7, as 200strap/1:2/CL7/tRD5 is disallowed before 450FSB
Consistent with a load increase, 500fsb/CL8 using 200 strap/tRD6, appears to need higher min vNB for same Large FFT (in)stability, compared to 333strap/tRD7.

Nice work there cheapseats, as always, very good. :up:
Yes the MST-81's are great; solid, heavy and fit perfectly on this board, I have two installed around the CPU area.Quote:

I'm going to use two of these on my case, one rear, one front:
http://www.newark.com/96M1768/fans-h...nki-9s1212f401
http://www.newark.com/productimages/...rd/4415648.jpg
Farnell in the UK should stock them, or Maplin electronics in Leicester as I remember.
I'm going with two small 80x15mm Sanyo Denki's on each of my HR-05 heatsinks. I like your idea of the S1L with a fan on it, I just can't be bothered filing away to make it fit, plus I already have an HR-05 IFX/SLI in my parts box anyway. Both fans on the HR-05's are being plugged into OPT_FAN 1 & 2. The case fans are being plugged into CHA_FAN 1 & 2.
I should have all the parts in a few days, but when I get it all installed I'll post some pictures here. I'm going to need some nylon washers for the HR-05, I read a review where the reviewer said even tighening down the thumb screw the heatsink still swivelled, adding a couple of washers under the M3 thumb screw should fix that problem.
That's the other thing, Thermalright in the instructions recommends thermal compound on the chip and the heatsink base plate! I don't think so, I think I'll put compound on the heatsink baseplate only, because its smaller than the surface of my Northbridge chip.
I picked this board up yesterday from the egg on a sale for $359 shipped. Looking forward to setting up with e86 and Gskill DDR-1600 HZ kit.
To start, what's the best bios for benching this board?
Rob2k, have you ever looked at this NB/SB heatsink/fan, the ThermalTake Spirit Extreme II?
http://c1.neweggimages.com/NeweggIma...116-018-03.jpg
From what I read on Newegg customer comments, it's largely good except for the failing fan. Although I have to wonder, how much better is that, than my current setup, the HR-05 SLI/IFX with 80x15mm Sanyo Denki fan, see below. I like the all copper look, matches the other copper heatsinks on the board, but I question how much more performance this ThermalTake heatsink would provide over my setup.
http://i442.photobucket.com/albums/q...s/HR-05Fan.jpg
Note, this is my Southbridge HR-05 SLI/IFX, and also the fan isn't on the back permanently, it will be located on the other side. My Northbridge HR-05 IFX will use the same type of fan.
Hi Aln688 - the Thermal Take sink looks like a neat N/B solution. I would stick with what you have for the N/B and CPU as I'm sure they will be good performers.
Probably worth running this passively on the S/B without a fan - I bet the temp won't rise above 40 degrees :DQuote:

What would you guys recommend as the best bios to get started with? I'll be getting familiar on air then going to LN2 in a week. I have seen successful screens using the 501, is that the best so far?
CPU - e86
MEM - 2GB DDR3-1600 D9GTS
Tx guys.
403, 501 and 901 all seem decent bios
anybody else have trouble using higher dividers when booting in at 600fsb, can only use the lower memory dividers giving between 1200mhz-1500mhz on the ram no matter what voltages set, i've had the ram running at 1900+mhz on the maximus i had but at a lower fsb
Hi Guys,
Thank you for sharing your knowledge and experience.
This thread has been already a lot helpful to me. I got the RE + Q9550 (water cooled) for about two weeks ago.
Which kit of DDR3 would you suggest as the best choice for my setup for now? Im aiming to run the Mem somewhere between 1800-1900MHz.
Would the CellShock 2GB DDR3 1600MHz run stable at 1900MHz with the Q9550?
http://www.memoryc.com/products/desc...kit/index.html
What about the 2GB Transcend aXeRAM DDR3 PC3-14400
http://www.memoryc.com/computermemor...c31440xmp.html
or 4Gb G.Skill DDR3 PC3-12800 TT
http://www.memoryc.com/computermemor...seriescl7.html
Which one would be the best choice?
go Cellshock if you can Ive had luck with my gskills running at 1960mhz 8-8-8-26-1T they were 1600 mhz stock 7-7-7-21
will post in the next few days some result i got with team xtreem 2x2gb pc3-16000 CL9
samsung hco's
pretty amazing vdimm.s
so far confirmed 1600 CL7 1.65v
i've only ran 0206/0401/0501 under cold so i can't really comment on whether the newer BIOSs are better or not for sub zero benches :shrug:Quote:

Thanks Glenboy and 3oh6.
Based on your suggestions and some from ocx, I'm going to start with 401 and then 501 to compare notes while I'm still on air.
Great thread.
1010 was worse, going back to 0901
you probably mean the 1001 ?? anyways i think i have to give this now bios a spin and see if its any goodQuote:

cheers mate thanks for answering i found out what it was after looking at cstkl1 screen shots (thanks for posting them) i noticed he had a much higher trfc, it was the trfc on auto was too tight at a higher ram speed (48) once i manually set it higher in the bios (88) i could boot 1800 mhz + no problem At 600fsb

Funny you mention that, I'm struggling to find a good combination of fans for my system. I'm referring to case fan, CPU fan and NB heatsink fan. I've came to the decision (as you already suggested) to run my SB fanless, I'm beginning to detest the amount of fans on my system, it's getting out of hand.Quote:

Now I'm struggling to get a good fan for the CPU. I received my Noctua U9B and Thermalright HR-05 IFX today, great parts. I need a 92x92x25mm fan *better* (translated: better airflow) than the Noctua supplied fan, it's 37 CFM/17dBA. I see Scythe does a 92mm fan, but it's sleeve, and I'm spoiled by that 120,000 hours MTBF of the SFF21Gs.
Then I've got the dilemma of NB heatsink fan, what do I use there? I have the Sanyo Denki 80x15mm, I plugged it in, I could hardly feel any air come off that fan, I mean it's quiet but airflow seems non existant, it's 21 CFM/20dBA.
I'm considering a Delta 92mm for the CPU, something around 50 CFM instead of the Noctua NF-B9 fan's 37 CFM, this is to make up for the fact my CPU heatsink is smaller. I'll post a picture over the next day or so of the board with the CPU heatsink sitting on the board with the HR-05 IFX.
FYI, that HR-05 IFX/SLI fits perfectly on the SB, especially since my Diamond 4870 X2 video card runs down about half way through the SB chip path.
Question to anyone, I have Kingston HyperX DDR3 1625 PC13000 RAM 4GB, 2 modules of 2GB each. Is it possible for me to have 8GB, 4 modules of 2GB each? Same type of Kingston modules.
I remember my old Intel DX48BT2 board had a huge yellow flier stating that in the case of 1600 MHz RAM that only a configuration of 4GB can be used. Since I've not saw anything like that mentioned in the Asus documentation, I wondered if it's possible.
Thanks.
