E6600 + Asus P5W DH Deluxe Adventures

Intel Core 2 Duo E6600 Conroe + Asus P5W DH Deluxe

Thanks to Asus, I finally got my hands on a Asus P5W DH Deluxe for the sole purpose of cranking out some nice benchmarks. This board is the newly revised P5W DH which later P5W DH Deluxes will feature a higher max MCH volts of 1.85v :woot:

System:

• Intel Core 2 Duo E6600 QPGE B1 Step 5
• Swiftech G4 Storm water cooled cpu
• Asus P5W DH Deluxe 0801 bios
• 256MB BFG 7800GTX 84.66 SLI drivers
• 2x1GB Gskill PC6400PHU2 2GBHZ Micron D9 (cooled by Sunon 92x38mm 120cfm fan on rheobus medium speed)
• 74GB WD Raptor 8MB cache
• FDD
• 700W OCZ GameXStream Psu

General observations and notes:

• The setup and installation went problem free so started some stock load tests.
• I read the guide to known P5W DH issues and workarounds at http://www.xtremesystems.org/forums/...d.php?t=110193
• I followed the guide FCG wrote at http://www.xtremesystems.org/forums/...d.php?t=106563 for preparing the board by reapplying the TIM on the Northbridge/MCH and Southbridge heatsinks and removed their respectively covers to allow the actual heatsinks to breathe. I also added a 120x25mm fan over my video card which cools my SB heatsink and another 120x25mm fan over the NB and cpu socket area.
• I plugged in my 74GB WD Raptor 8MB drive into the red SATA1 connector on motherboard as explained in the manual
• Get use to the board auto shutting down on exiting bios, memtest or windows and automatically booting up again at speeds other than default 266fsb. Seems it's like Intel D975XBX Badaxe when changing boot straps. It's the boards way of ensuring the bios settings are properly set for booting. Can be quite annoying when rebooting windows when doing benchmark sessions. Actually, I got a reply from an Asus contact about the auto power down:
  
  Quote:

  This behaviour is caused by system's limitation. For over-clocking, the
  internal PLL of NB would not lock on the high clock right away, so that means
  system could not hold on the clock frequency immediately after reset. That's
  why we add a auto-power down scheme to fix this issue. Of course, this
  behaviour only occurs at over-clocking scenario.

• Seems AI Booster under reports cpu temps by around 8-10C. Coretemp app reports stock cpu idle and load temps in line with what my Intel D975XBX Badaxe Rev304 motherboard for this Core 2 Duo E6600 Conroe cpu.
• AI Booster loads awfully slowly and like Asus Probe II app both consume too much memory when open for my liking >10-12+ MB per app!
• AI Booster has a habit of not displaying the right temp with occassional jumps to 255C.
• AI Booster reported memory voltage is inaccurate i.e. 2.1v in bios = 2.2v in AI Booster, 2.2v in bios = 2.3v AI Booster, 2.3v bios = 0.00v AI Booster, and 2.35v = 6.54v in AI Booster!
• In bios monitoring section it can momentarily freeze or hang on you, no one knows why but if you wait a tad longer it will function fine and no probs. Just another issue to get use to.
• The board does droop alot more than Intel D975XBX Badaxe (which was fairly stable on vcore when Enhanced Power slope was enabled). P5W DH doesn't have such a function to reduce drooping on vcore voltage. There's around ~0.03 to 0.05v vcore droop under load in windows. For example, 1.425v in bios = 1.40-1.41v idle vcore in AI Booster in windows and under load that droops to around 1.376-1.384v.

Dual Stressprime 2004 'Orthos' dual core testing:

Note:
1. vdimm of 2.1v in bios shows up as 2.15v in AI Booster.

------------------------------------------------------
Stock 2400mhz at 1.242v vcore (AUTO):

vCore = AUTO
fsb = AUTO
vdimm = 2.1v
MCH = AUTO

Coretemp = 29-30C

Load:
AI Booster = 29C
Coretemp = 37-39C

------------------------------------------------------
3207mhz at 1.242v vcore (AUTO):

------------------------------------------------------
Seems to be about the same as on my Intel D975XBX when @3600mhz at 1.376-1.384v vcore load (Badaxe needed 1.371v vcore) but with P5W DH needed to raise MCH volts from 1.55v to 1.65v :) P5W DH consistently needs around 0.05v more vcore under load than what i needed on Intel D975XBX Badaxe heh.

vCore = 1.425v
fsb = 1.3
vdimm = 2.1v
MCH = 1.65
ICH = AUTO

Super Pi @9x400fsb = 3600Mhz 1:1 4-4-4-12 at 2.1v
32M Single = 14min 21.421s
32M Dual = 16min 12.000s / 16min 13.437s

Isolated memory clock tests:

Now that I've found a nice stable reference clock to work with (3600mhz at 1.376v), it's time to fine a nice stable memory clock to work with using async upclock dividers. I used memtest86+ v1.65 and in windows Systool dual 32M PI (cpu test) runs to do some fairly quick tests. I've found if you can pass Systool dual 32M PI (cpu test) you can fairly easily pass Super Pi 32M single and dual instance tests :)

Memtest86+ v1.65:
All tests done at 4-4-4-12 4 timings:

• 501mhz at 2.20v = PASSED
• 513mhz at 2.25v = PASSED
• 513mhz at 2.30v = PASSED
• 517mhz at 2.30v = FAILED with 2 errors on 2nd pass of Test #5
• 520mhz at 2.30v = FAILED with 14 errors 1st pass of Test #5
• 520mhz at 2.35v = PASSED
• 525mhz at 2.35v = PASSED
• 528mhz at 2.35v = FAILED with 4 errors on 4th pass and 2 errors on 6th pass of Test #5
• 533mhz at 2.35v = FAILED with 558 errors on 1st pass of Test #5
• 534mhz at 2.40v = PASSED

Super Pi v1.5 - single and dual tests:
----------------------------------------------------------------------------
I set 800 (2:3) upclock divider to test my 2x1GB Gskill PC6400PHU2 HZ Micron D9s @4-4-4-12 4 timings. I set bios to:

fsb = 334fsb
vcore = 1.35v
vdimm = 2.20v (AI Booster reports 2.3v)
fsb = 1.3v
mch = 1.65
ich = AUTO

334fsb with 2:3 upclock had the memory running at 501mhz 4-4-4-12 at 2.2v. It failed Systool dual 32M PI (cpu test) near the end. So i dropped fsb from 334fsb to 333fsb via AI Booster app so that memory was running at 500mhz 4-4-4-12 at 2.2v. At 500mhz 4-4-4-12 it passed Systool dual 32M PI test fine. So ran single and dual Super Pi v1.5 32M tests with the following results @9x333fsb = 3001Mhz:

Super Pi @9x333fsb = 3001Mhz 2:3 500mhz 4-4-4-12 at 2.2v
32M Single = 16min 21.859s
32M Dual = 17min 42.062s / 17min 39.641s

----------------------------------------------------------------------------
Now from quick memtests and Systool dual 32M PI (cpu tests) with 2.3v vdimm in bios, memory found it's stable mark at 513mhz 4-4-4-12 at 2.3v.

vcore = 1.35v
vdimm = 2.30v (AI Booster reports 0.00v heh)
fsb = 1.3v
mch = 1.65
ich = AUTO

Super Pi @9x342fsb = 3082Mhz 2:3 513mhz 4-4-4-12 at 2.3v
32M Single = 15min 55.500s
32M Dual = 17min 14.547s / 17min 12.328s

----------------------------------------------------------------------------
Bump memory voltage to 2.35v vdimm in bios, and managed to get memory to 525mhz 4-4-4-12 at 2.35v.

vcore = 1.35v
vdimm = 2.35v (AI Booster reports 6.54v LOL buggy heh)
fsb = 1.3v
mch = 1.65
ich = AUTO

Super Pi @9x350fsb = 3154Mhz 2:3 525mhz 4-4-4-12 at 2.35v
32M Single = 15min 30.609s
32M Dual = 16min 51.375s / 16min 48.594s

----------------------------------------------------------------------------
Bump memory voltage to 2.4v vdimm in bios, and managed to get memory to 533mhz 4-4-4-12 at 2.4v. systool dual 32M PI (cpu test) failed near end of run at 534mhz 4-4-4-12 at 2.4v, so using clockgen bumped it down to 533mhz 4-4-4-12 at 2.4v which passed fine.

vcore = 1.35v
vdimm = 2.4v (AI Booster reports 0.01v)
fsb = 1.3v
mch = 1.65
ich = AUTO

Super Pi @9x355fsb = 3200Mhz 2:3 533mhz 4-4-4-12 at 2.4v
32M Single = 15min 20.453s
32M Dual = 16min 36.657s / 16min 33.500s

So looks like for Super Pi v1.50 32M at least I've managed to get 2x1GB Gskill PC6400PHU2 2GBHZ Micron D9GMH to 533mhz 4-4-4-12 at 2.4v.

Next up.... finding P5W DH's max fsb limit at 1.65v MCH and 1.85v MCH :D




.

Max FSB Results:

Now the fun part, finding the max fsb this P5W DH is capable of :) With FSB volts at 1.3v and MCH volts at 1.65v for now I managed being able to boot from bios at 9x442fsb = 3978Mhz at 1.54-1.55v.

I tried 9x444fsb but not able to boot up. Whether that's a fsb limit of cpu/vcore/cooling limited not sure - will investigate later :D

9X442fsb = 3978Mhz

Next I'd drop the cpu multiplier using Crystalmarkcpuid for 8x and see how high I can take the fsb still with MCH volts at 1.65v.

To test max fsb, I decided to boot into windows from bios at 9x440fsb = 3960mhz at 1.575v vcore bios (1.54-1.57v windows load-idle) and then using Crystalmarkcpuid to drop from 9x to 8x cpu multiplier for tests.

I used only Systool dual 32M PI (cpu test) and Super Pi v1.50 single and dual 32M tests to test max fsb.

Bios Settings:

vdimm = 2.2v
vFSB = 1.3v
vMCH = 1.65v
vICH = AUTO
Performance mode = AUTO
Hyperpath3 = Disabled

@8x440fsb = 3522mhz 1:1 memory @440mhz 4-4-4-12 4
I managed to pass single 32M Super Pi but one core failed dual 32M Super Pi with vMCH of 1.65v.

Super Pi v1.50
single 32M = 14min 14.703s
dual 32M = core 1 failed at 17th iteration

Increased vMCH to 1.75v in bios and 8x440fsb dual 32M Super Pi completed with no problems.

http://fileshosts.com/intel/Asus/P5W...rpi-32m_tn.png

How far can we take fsb with vMCH 1.75v ? Seems 447fsb was only good enough for single 32M Super Pi, as dual 32M failed. So dropped back to 445fsb which passed fine.

@8x447fsb = 3576mhz 1:1 memory @447mhz 4-4-4-12 4
I managed to pass single 32M Super Pi but one core failed dual 32M Super Pi at 19th iteration on core #2 with vMCH of 1.75v.

Super Pi v1.50
single 32M = 14min 04.844s
dual 32M = core 2 failed at 19th iteration

@8x445fsb = 3561mhz 1:1 memory @445mhz 4-4-4-12 4

Super Pi v1.50
single 32M = 14min 09.438s
dual 32M = 15min 48.875s / 15min 46.640s

http://fileshosts.com/intel/Asus/P5W...rpi-32m_tn.png

Summary of max FSB tests:

Right now it looks like for stock heatpipe cooling on MCH/NB:

vMCH = max fsb
1.65v = ~438fsb
1,75v = ~445fsb
1.85v = not tested yet

I guess the default chipset latencies are very tight and the factor of adequate MCH/NB cooling come into play. FCG's FSB scaling report at http://www.xtremesystems.org/forums/...d.php?t=105940 refers to better cooled MCH with MCH volt modded AFAIK. Also, I have yet to test simonmaltby's fsb scaling frequency tests in relation to memory timing options for tRD and tRFC http://www.xtremesystems.org/forums/...d.php?t=111400.

Nice one, what is the revision code of this board Eva, and is this board in stores or do we have to wait ? :)

edit , well, it`revision rev. 1.02G , see http://www.xtremesystems.org/forums/...d.php?t=112614

Great post eva, thanks for the info. Wanna sell me your E6600? :)

Eva, did you see my reply @ http://www.xtremesystems.org/forums/...=111400&page=2 ? I am curious if asus can do the same with the asus p5b non deluxe ...

Sweet stuff man, looking forward to a "high" fsb at 9x !:cheer:

thanks guys.. nah not selling my E6600s as yet - they're my precious babies :D

replied http://www.xtremesystems.org/forums/...4&postcount=51 :)

nice job here ^^

have you checked if the vcore stood 1.24 with auto setting when doing 357 fsb ?

i've noticed that vcore increase when overclocking with the P5B dlx

Very nice job! :)

very nice bravo!

Nice post! :thumbsup:

thanks guys..

yup AUTO vcore = 1.242v i checked according to AI Booster at least.

Updated 2nd post with 9x442fsb screenies straight from bios boot :D

Well Eva, I was thinking. I am curious what a retail conroe E6600 does with those higher mch voltages. I mean, it`s nice that an ES sample will do 9 x 450, but, what about the retails ? Like 10.000 xtreme members have a retail and like 25 people have an ES so......

It`s cool from Asus they did the modification but it`s also nice if we can see the difference with a b2 stepping :D

easy buy me a E6600 retail and send it my way as a gift.. no limit as to how many guys can send to me.... :hehe: :ocau: :D

nice job and thx for sharing!!!

With my retail E6600 VMCH makes absolutely no difference in stability whatsoever. Only VCore-the more I give it, the higher I can go stable. I think VMCH only comes into play at 400FSB+.

Hey eva! Thanks for the results :D Got a question about this part if ya dont mind :)

Did your gear do this out the box fairly quickly, or did you have to edge the CU and board there? I`m having trouble getting over 3GHz on my setup with the CPU at 1.36 under water, and improved air on the NB at 1.55V.

Also, have you been measuring VCore idle and load with a DMM on the board? i`ve been checking mine (between CPU socket and top of board) and I have very little droop at all..definately not enough to worry about. Am I looking in the wrong place?

Final question/point :)... I ditched the heatpipe cooler for the VRMs between the CPU socket and I/O ports totally..the thick rubber-like pad does NOTHING for heat conduct, and I found, after applying AS5 to the VRMs, that they`re not all at the same height and the copper block doesnt make good contact at all on it. I`m using RAMsinks over the VRMs with a fan over them, and they`re not hot at all. The small moulding pits in the VRMs dont make cooling easier either. What do ya think?

Any input ya got on any of those questions is welcome :)
Thanks,

Kenny

'Sata3' threw me off for a second i was like wait do i have mine in the wrong port
but by sata3 you meant sata2 like sata 3.0gb/s right
because mine is the 'red' one but i thought that was #1

is the board stable at 440fsb?
do you have to enable SPD timings to get that FSB (no need to make them higher or lower, but do you specifically need to change it to default SPD?)

1.65v MCH and 1.2v FSB... do you consider that 24/7 safe with a fan?

Sorry, what type of NB cooling do you have?

Also, to avoid a new thread...does the board run a 4:5 divider alright? Have some DDR1000 coming, and was hoping it'd work (what is the setting for the 4:5 divider btw? Intel dividers confuse me)

As usual, very through insight, George :) Thanks for taking time to put it all together :up:
I wish there were even more threads like this - success stories and "DIY" problem solvers, if there were any.
Kudos :toast:

Its the same as ES..
No difference..

You wont need to raise VMCH at 400FSB, gettin' 500FSB on the other hand, you need too raise it a bit... - Lets say 1.75-2.0v, I dont remember the exact, but with stock sink on my board, I've hit a 53x FSB at 2.0v, but - no way with X9 on my retail CPU..

haven't measured via dmm only software heh but i believe the droop is correct

3.6ghz out of the box was easy as pie hehe

not sure about VRM cooling i have the heatpipe on but reapplied TIM on it and have removed those covers as i stated above

corrected typo SATA1 hehe, 9x440fsb isn't stable going to drop multipler to find the max fsb.. i have timings manually enabled never SPD with no probs

1.65v MCH i would consider safe if you have the cooling i'd probably change the stock NB heatsink if you want to run it 24/7 - i'm going to use Thermaltake Extreme Spirit II NB heatsink since i'll take it off my Bad axe hehe

re-read 1st post stock heatpipes with covers off, reapplied TIM and fan over them.. haven't tried 4:5 yet i've only had this P5W DH for less than 48-72hrs need time to test hehe

i had to raise my MCH from 1.55v to 1.65v to get 9x400fsb = 3600mhz at 1.376v stable as i reported in 1st post ;) at 1.55v it will error out in stressprime after a few minutes

as to questions of where my ES came from, i could tell you but i'd then have to kill ya :p: LOL

more results coming soon :D

What a smart design !! :slobber:

Starting to test max memory clocks for 4-4-3-8 timings, but weirdest thing is happening in that i can't even get 472mhz 4-4-3-8 stable in memtest test #1-5 tests regardless of vdimm used while the same 2x1GB Gskill PC6400PHU2 HZ can do 500mhz 4-4-4-12 at 2.2v and 533mhz 4-4-4-12 at 2.4v on P5W DH!

Same memory on Intel D975XBX Bad axe can do 490mhz 4-4-4-8 at 2.2v and 473mhz 4-4-3-5 at 2.2v with air cooled MCH/NB and 488-494mhz 4-4-3-5 at 2.2v with water cooled MCH/NB.

i did 488mhz 4-4-3-5 at 2.2v easy on Intel D975XBX Bad axe.

http://fileshosts.com/intel/Intel975...0s531ms_tn.png

so far on P5W DH can't even get memtest to pass error free at 472mhz 4-4-3-8 tried 2.2, 2.25, 2.3, 2.35 and 2.4v vdimm no go heh

:confused:

more testing needed i guess :)

nice post, I have the same chip and board....

but I havent changed any of the other voltages... I really dont know what they are.... will they allow me to boot at higher fsb?

With my current settings, 400 x 9 is rock solid... anything over doesnt even try.

thx :toast:

i leave vfsb and mch at 1.3 and 1.65v respectively and ICH at AUTO

More memory testing...

After testing 2 sets of 2x1GB Gskill PC6400PHU2 HZ Micron D9GMH memory, it seems pair #2 is doing much better than pair #3 so far :)

Pair #2
* 510mhz 4-4-4-12 at 2.20v
* 519mhz 4-4-4-12 at 2.25v
* 523mhz 4-4-4-12 at 2.30v
* 533mhz 4-4-4-12 at 2.35v
* 541mhz 4-4-4-12 at 2.40v

vs

Pair #3
* 501mhz 4-4-4-12 at 2.20v
* 513mhz 4-4-4-12 at 2.25v
* 525mhz 4-4-4-12 at 2.35v
* 534mhz 4-4-4-12 at 2.40v

Pair #2 of 2x1GB Gskill PC6400PHU2 HZ Micron D9GMH (0629) managed single 32M @542mhz 4-4-4-12 at 2.4v and dual 32M @541mhz 4-4-4-12 at 2.4v using default advance timings

Unfortunately, my P5W DH with 0801 bios with 2x1GB Gskill PC6400PHU2 HZ Micron D9GMH (0629) doesn't seem to like 4:5 upclock divider past 378fsb (gives 472mhz mem) for now :( Nor does it like 2:3 beyond 360fsb (gives 541mhz mem). This is with manually set timings of 4-4-4-12 regardless of vdimm used. Haven't tried setting SPD for memory to boot yet.

P5W DH i have doesn't seem to like 4-4-3 timings where tRP = 3 either, can't pass memtest86+ v1.65 higher than 460-472mhz 4-4-3 (manually set in bios) regardless of vdimm used or divider used. Same memory on Badaxe board did 488mhz 4-4-3-5 at 2.2v!

But 1:1 seems best for E6600 due to max fsb limitations I wonder how far i can go just for testing single Super Pi v1.50 32M :)

Testing max single Super Pi v1.50 32M:

vdimm = 2.3v (seems to help stable things due to tighter timings at 1:1 clocks especially when you get closer to P5W DH's max FSB wall)

Bios Settings:

vFSB = 1.3v
vMCH = 1.65v
vICH = AUTO
Performance mode = Standard
Hyperpath3 = Disabled
DDRAM Throttling = Disabled

* All tests are straight boot from bios with manual timings set at 4-4-4-8 4 at 2.3v
* All tests are untweaked with default P5W DH set timings. Have yet to even tweak with memset or drop tRP to 3 yet.

Yes I could sneeze and break 13min :D

eva

thanks for this post. it help me to finally get a decent o'clock out of this board. currently sitting at 3.51.

thanks again

Glad I could help :D

Now to try tighter memory timings of 4-4-3-8. I started to test at 9x437fsb = 3934Mhz 1:1. It seems for default P5W DH advance timings I can pass 32M find. But if I try tightening the advance timings in memset @437mhz 4-4-3-8 it will fail..... unless I loosen tRD from 6 to 7. Then I can tighten all the rest of the memset timings while keeping tRD at 7 :)

Bios Settings:

vCore = 1.65v
vDIMM = 2.3v
vFSB = 1.3v
vMCH = 1.65v
vICH = AUTO
Performance mode = Standard
Hyperpath3 = Disabled
DDRAM Throttling = Disabled

@3934Mhz - 9x437fsb, default P5W DH timings (left) vs memset tweaked timings with tRD set at 7. (right)
Super Pi 32M = 13min 04.594s vs 13min 01.125s

So decided to use Clockgen to boost fsb from 437fsb to 440fsb and guess what with tRD loosened to 7, it passed fine without needing vMCH of 1.75v! This was done with vMCH of 1.65v @3962Mhz - 9x440fsb 4-4-3-8 :)

http://fileshosts.com/intel/Asus/P5W...4s937ms_tn.png

Time to try and max out this E6600 of mine :D

Analysis of P5W DH memory 4:5 and 2:3 dividers

I've been messing around with 4:5 and 2:3 dividers are lower FSB clocks and checking memset to see what values are being set since i'd having issues in memtest86+ v1.65 test #7 errors in high fsb 4:5 mode.

In 2:3 I maxed out my memory @542mhz 4-4-4-12 at 2.4v which showed the following memset timing values

http://fileshosts.com/intel/Asus/P5W...3s859ms_tn.png

tRFC = 42
tRD = 6
Write to Precharge Cmd = 13
Write to Read Cmd = 10
Read-Write Turnaround CLKs = 8
Write-Read Turnaround CLKs = 6
tRTP = 5

Now in 4:5 mode the only changes in memset are for:

tRFC = 35
Write to Precharge Cmd = 12

As you see it's tighter than at 2:3 set memset timings. So I booted into windows from bios at 9x378fsb 4:5 with memory at 472.5mhz 4-4-4-12 at 2.3v and used clockgen to clock up incrementally to test the max FSB:MEM clocks and find out how loosening these memset options will effect max 4:5 FSB:MEM clocks.

Results:
Using Systool dual 32M PI (cpu test), I managed to use Clockgen to raise FSB from 378fsb to 394fsb (493mhz 4-4-4-12 for memory) before it started to fail/error out. This was still with default memset timings where tRD = 6. I then raised tRD from 6 to 7, and easily managed to raise FSB from 394fsb to 400fsb (500mhz 4-4-4-12 for memory) and pass the tests without errors!

With tRD = 7, i could even tighten tRFC from 35 down to 20 with no problems.

@3600Mhz - 9x400fsb 4:5 500mhz 4-4-4-8 at 2.3v (more vdimm allows to handle tigher tRFC values but tRD needed 7)
http://fileshosts.com/intel/Asus/P5W...6s422ms_tn.png

So it does seem for 4:5 divider the culprit maybe tRD = 6. Now some folks managed to get high 4:5 clocks on P5W DH and I suspect this due to higher voltages or voltage mods on vdimm and vMCH as these two voltages help the memory/MCH handle the tight tRD value of 6 apparently. With enough voltage you could clock the memory higher for 4:5 ratio :)

Seems to me that for 975x chipset, both the max FSB limits and inability to handle high fsb in 4:5 and 2:3 dividers all comes down to tRD being too tight at 6. How far you can take your FSB and clocks in async divider mode, depend on:

1. MCH/NB quality and latencies
2. MCH/NB cooling - better MCH/NB cooling = higher FSB and higher memory clocks
3. MCH Voltage
4. Memory modules used - if the memory can handle tRD = 6 well then it will clock higher, allowing high FSB
5. vDIMM - memory voltage helps memory handle tighter advance timings, thus higher max FSB

corrected typo SATA1 hehe, 9x440fsb isn't stable going to drop multipler to find the max fsb.. i have timings manually enabled never SPD with no probs

1.65v MCH i would consider safe if you have the cooling i'd probably change the stock NB heatsink if you want to run it 24/7 - i'm going to use Thermaltake Extreme Spirit II NB heatsink since i'll take it off my Bad axe hehe



re-read 1st post stock heatpipes with covers off, reapplied TIM and fan over them.. haven't tried 4:5 yet i've only had this P5W DH for less than 48-72hrs need time to test hehe


thanks mate... :D


i had to raise my MCH from 1.55v to 1.65v to get 9x400fsb = 3600mhz at 1.376v stable as i reported in 1st post ;) at 1.55v it will error out in stressprime after a few minutes

as to questions of where my ES came from, i could tell you but i'd then have to kill ya :p: LOL

more results coming soon :D

Hehe, well I dont need to know neither, they're quite easy to get :)
Was to the "on retail FSB" part ;)
Hmm, this is odd, I use alot higher vcore, but thats quite normal for step6, also due my board has MAJOR Vdroop.
Hmm, one odd thing though, my mem, they wont run P95 stable at speeds even 100mhz lower than benchable.. - They do 4-3-2-4 at 530mhz, but wont do 4-3-2-4 at 400mhz, odd..? I'd like 4-4-4-4 at 500mhz, gonna give it a shot with raising the vmch, but cant really see that helping, but if theres a chance, its sure worth doing :)

Further proof, i upped vdimm to 2.4v with vMCH still at 1.65v and booted into windows at 9x390fsb 4:5 487mhz 4-4-4-8. Using memset loosened timings to match that of default 2:3 divider tRFC = 42 and Write to Precharge Cmd = 13 but loosened tRD from 6 to 7. Managed to clock memory right up to 540mhz 4-4-4-8 at 2.4v without problems for single 32M and 538mhz 4-4-4-8 for dual 32M.

Decide to push my E6600 a bit harder with stock heatpipe MCH/NB heatsink still, i bumped vcore and vMCH in bios to 1.675v (1.64-1.65v windows) and 1.85v respectively and managed to pull off

Wish you could test a x10 multi with , to know what max fsb you get

Anyway , that's what I'd call a golden P5W DH ....:p:

Radiical Chipset Waterblock Installation

Time has come to remove stock heatpipe MCH/NB heatsink and replace it with Radiical.com.au chipset waterblock :D

First, I cut a piece of sticky back insulation foam horizontally to a paper near paper thin height and stuck it on the 2 corners of MCH green PCB near the hooks. Just added precaution in case i crush the MCH chipset core heh. Second, I put some Microcool silver mosfet heatsinks on the mosfets near the cpu socket.

http://i4memory.com/reviewimages/mot...hipset_001.jpg http://i4memory.com/reviewimages/mot...hipset_004.jpg http://i4memory.com/reviewimages/mot...hipset_005.jpg

Then mounted the Radiical chipset waterblock.

I hoped it would have been stable higher than that for 1M with 1.85v MCH. I have a faulty pci-e slot so I was going to RMA for one of the newer revisions.

I notice you are running your ram at 1:1 with 450+ FSB, my board wont boot at 1:1 above 430 FSB so i dropped to 4:3. Maybe you can get higher FSB with 4:3 ??

Great post btw, look forwards to see how your chipset waterblock fares :)

That's a very nice looking chipset waterblock you have there, Eva. As usual, a very methodical and informative presentation of your observations. Thank you.

really nice effort and findings there eva ,very helpfull

Top notch info and presentation as always Eva2000 :toast: Very informative and detailed,i bet this will help alot of us that is struggling with our P5WDH boards :clap:

Eva I got B2 revision chip , settings are in my sig. Currently I am sitting at 400x9 fully stable , games /Orthos :)

However I got Perf.mode set to "turbo " -should I switch it to "standard " if I d like to go higher ?
I ve got a nonmodded MB though and B2, so it s like a 3700-3800 maximum, but I d like to try .

THX:p:

thanks guys .. hope this thread does help other P5W DH users, it basically outlines everything :D

yup the chipset block is sexy ain't it :)

with 4:3 divider you can push max FSB higher since as I stated tRD = 6 is too tight for memory so it would make sense lowering memory clock will allow the memory to handle tRD = 6 and thereby allow FSB to go higher in 4:3 mode :)

I'll test 4:3 divider a bit later to see as well.

As to performance modes not sure i've only used Standard extensively since i started with P5W DH. Will have to try Turbo mode too.

eva, I have to thank you for suggesting tRFC being loosened earlier in this thread. It helped me run 4:5 up to 480MHz (up from ~460)...but not much higher. (Memory is capable of 540MHz) So far I've been trying pushing tRD to 7 and running Standard performance mode, but unfortunately neither is seeming to help me break past this. Seems like this ram just isn't playing well with this board. :-/

I think you will find favorable results running Turbo. I've personally never tried Standard except on a couple of occasions. Testing only 1M it appeared a bit slower and didn't help me gain any raw speed.

glad i could help, did you max your vdimm too 4:5 needs more vdimm that what your modules ran in 1:1 if you want to keep things very tight on timings as well..

I put a thermal probe on top of my chipset waterblock too. At 9x448fsb = 4032Mhz at 1.675v (1.65v) and 1.85v MCH volts, even the top of chipset block gets hot ~40.5C to 42.5C under 32m Super Pi load and ~20C idle at 1st boot and rises to around ~26C idle in windows and post 32M load around ~39.1C idle consistently. This is with 22.5C room temps. This really does say don't use 1.85v MCH volts on air cooled MCH/NB heatsinks as it must get bloody hot!!!

I started with early memset86+ v1.5 testing, hoping that water cooled MCH/NB would give me higher memory clocks like it did on Intel D975XBX Badaxe. Unfortunately, the improvement in memory clocks was minor at 2:3 divider.

At 2:3 divider:

* before stock heatpipe air cooled MCH = max memory clock was 542mhz 4-4-4-12 at 2.4v
* radiical chipset water cooled MCH = max memory clock 542mhz 4-4-4-12 at 2.4v but could pass one loop of 545mhz 4-4-4-12 at 2.4v before memtest froze.

At 4:5 divider improvement was a bit better than at 2:3 divider even though tRD is still set too tight at 6:

* before stock heatpipe air cooled MCH = max fsb/mem clock before test #7 errored was at 378FSB with mem at 472mhz 4-4-4-12
* radiical chipset water cooled MCH = max fsb/mem clock before test #7 errored was now at 392FSB with mem at 490mhz 4-4-4-12

Max FSB at 1.65v MCH volts with dropping cpu multiplier to 8x, seems to still be around the same as on air at 438FSB. This could either mean I have a bad chipset waterblock mount, or it's not temps that is limiting FSB at 1.65v MCH volts but voltage itself or the memory used or more likely the tightness of the memset advance memory timings used. Even at 9x multiplier seems with 1.85v MCH the FSB limit has only improved a tad from 447FSB 32M to 448FSB 32M, it could be related to memset timings as i tightened them from the default to get the best 32M times or it could be due to vcore or cpu cooling since 9x448FSB is 4032Mhz :)

I'm leaning to either too tight memset values or a bad chipset waterblock mount as I did have a bit of trouble mounting the 2nd thread hook to the motherboards' hooks, so will remount it a bit later.

But for now still on first mount of chipset block, I managed to pull of a dozen runs of 32M at 9x448-449fsb testing different memset timings :)

On stock heatpipe MCH heatsink best i could do was 9x447fsb = 4023mhz for 12min 43.609s

Now with Radiical Chipset waterblock cooling MCH here's what i managed:

@9x448fsb straight boot from bios and memset set tRFC = 26 and other timings dropped to what you see below

Wow Eva, good read!

My vga is dead, so i haven't had the opportunity to test my E6600/p5wdh/D9GMH rig.
So lot's of new and good info here for me! This will defenitly give me a nice start once i start testing my stuff :)

And is there anyway to get more vdimm? So you could run like 9x449 4:5 :D
It seems you can't run both max. cpu and ram clocks.

eva2000, how much FSB with multiplier 7 ?
I'm trying with aircooling and 458FSB SP8M @ 1.700V measured from board

Do all the Rev. 1.02G have that high of VMCH enabled? That's the revision I have but I don't have my conroe yet x.x I'm so damn excited to plug this thing in just to find that out :P

Edit: I did read that thread, too.. It wasn't really clear that Rev.102G have 1.85VMCH.

Nope 1.02g some have 1.65v and some 1.85v mch.

this is an Asus app we are talking about. We should not have to "get used to it". They should FIX IT. Is is painfully slow even on the fastest system and like you said the readings are all over the place. Come on Asus, get on the ball and give us a little monitoring app that actually works, and while you are at it, loose the cutsey (ugly), stupid, bloated interface of both ai and pcProbe2. yuck . . . :rolleyes:

That rant asside, this is the most informative thread I have read here in a long time. Kudos!! and thanks!

It sounds like watercooling the chipset may not be worth the trouble as compared to just using a third party chipset cooler with a fan. By the way, I've been running at 1.85v on the chipset and temps really haven't been really all that bad with a heatpipe style chipset cooler. Mostly low 40's I would say.

could be a bad chipset mount by me hehe won't know until i do a remount later :)

as to monitoring are we talking about same thing ? i'm talking about bios not windows apps like AI Booster/PC Probe2

No I was referring to your comment about aibooster or pcprobe apps that just don't work right. Did the waterblock for the chipset come with those little mounting hooks?

oh that... well i never said to get use to it for ai booster/pc probe 2 issues... i was referring to bios monitoring temp freeze :)

the hook threads are optional extras you order with radiical chipset block you will need to order them in addition to the chipset block IIRC AUD$5 extra = US$3.75-4.00 extra... you normally need to bend them yourself to suit your board's hooks but i asked if they could bend them for me as they look like they're fit for me heh

Soooo .... did you ever check your northbridge waterblock mount? Was it good?

well i remounted it and got an even lower max fsb by around 4fsb at each vMCH voltage lol

remounted again and got slightly better than 2nd mount... but yes a good mount means better fsb... i'm going for a 4th mount soon since i'm trying this P5W DH on phase http://www.xtremesystems.org/forums/...d.php?t=114486

Interesting when setting up my phase change gear and transporting the chipset cooling loop over to the new position, I noticed the MCP350 pump outlet barb tubing had been kinked for a while now as you can see the tubing near the outlet barb had memory effect of a collapsed tubing... maybe this is a possible reason why i didn't gain much in max fsb on water cooled chipset ??

hey eva ... can you post a pic of the Extreme spirit II on your chipset ? did you just cut off the pipe or if not, how are you cooling the mofsets near the cpu socket ??? I am planning to add some additional cooling to my NB chipset ...

thanks !!!
