***Official Asus P5WDG2 WS PRO & P5W64 WS PRO Thread***

[ted34]

As these 2 boards are so similar in overclocking it seemed to make sense to make thread for both of them. Apart from the obvious 4 pci-e slots on the P5W64 then even the bioses are very similar. The P5W64 is slightly better at clocking as its bios has couple of extra memory tweaking options.

P5WDG2:
All bioses including beta's can be found here as well as volt mods and pencil mods:
http://infomb.googlepages.com/home

I have tried the 0408 and 0005 and have found the 0005 much better and far better than any of the other bioses available for stability. a lot of the bioses overvolt but a couple do undervolt so becareful if you go from an overvolting bios to an undervolting bios.


P5W64:
Fair few of the bioses can be found here:
http://www.overclock247.com/day187/
Important: Do not change the VID Cmos Setting and the Microcode Updation and later bioses allow disabling of 1 cpu core.


General settings:

IDE Configuration: Set ide detect time out to minimum for quicker bootup.

In cpu settings disable all of the below and this then generally allows higher cpu clocks (at standard they all disabled except for Virtualisation Technology):
Max cpuid value
Execute Disable Function
Enhanced C1 Control
Virtualisation Technology
Cpu Internal Thermal Control
Intel Speedstep tech

In ram settings disable:
Dram ECC mode (unless using ECC ram)
Dram throttling threshold
Hyper Path 3

If struggling to get ram stable then try changing the below. These are only available in the P5W64 bios and for P5WDG2 the RMS and TRFC have to be changed using memset. Hopefully a bios with more tweaking options will be released in future for the PRWDG2:
Refresh Mode Select (RMS) to 15.6, 7.8 or 3.9us
Refresh Cycle Time (TRFC) to 42
Read delay to 7 or more


Overclocking and volts:
Vcore volts vary a lot between bios setting and actual setting so be careful and go by your temps reported by TAT or coretemp and not by Asus or other board software.
Fsb: 1.4 max. (Generally 1.3v is enough unless your using high fsb)
Mch (Chipset): The chipsets get hot so remove the useless plate from the top of the heatsink and let the fins breath a bit more. Stick a fan blowing over this or use water to cool it. For volts 1.8v+ is needed to run on a divider so test at 1:1 first to check cpu and memory and eliminate the board. For more than 1.8v use a voltmod.
Ich: Set to 1.2v

This is one of the best boards for overclocking i have ever used! my rig has been running this board since release at 3.6G. iam running a beta overclocking bios 0005. it was available for download from ES for 1 hour before being removed as it was a direct bios from an asus engineer so it was said, but its in the link above! so i guess its cool!

What i have done to the board!

first off i ditched that silly heatpipe config, made of aliminum and where the pipe enters the heat sinks its only glued. Heat transfere through glue isnt so good as i recall. replaced chipset heatsink with a microcool heatsink fitted with a nice quiet sunon fan for cooling.

keap the heatsink for the fets but placed an active fan above it. also used micro cool sinks for the caps around CPU as some do get kinda toasty!

sorry about the pic, taken with my phone.

as you can see its water cooled by a resorator system of my own config. i have a fan controler as well for all internal fans which are quiet! the cpu block is a TT and the 1900 XTX is also watercooled.


no volt mods! for a change and this board has never crashed or blue screened.

My complete system was based on this board because i needed PCI-X

Asus P5WDG2-WS bios 0005
2g Ultra talent DDR2 ( fat body D9 chips )
Seasonic 650w PSU
1900 XT-X
XFI-fatality sound card
Adaptech 39320A-R PCI-X SCSI card
2 X 36g 15000rpm atlas drives in host raid O
1 X 250g serial ATA seagate
2 X 16X nec dual layer DVD optical drives

a fantastic board that no one should overlook! nice one asus!

 

[Noto]

tag!

im looking to get one of these babies for my 6600, and only getting to 3.2-3.4. Ill be happy with that. Hopefully it wont need as many mods as above ^^ but some interesting things u mentioned about the caps etc.

thinking of replacing my p5w64 with badaxe 2

problems with these board theres loads

1.onboard sound optical & coaxial outputs, only output 2
channel stereo and also puts about 14 loading bars
onto windows scroll bar

2. reports of firewire ports dont work

3.double restarts soon as you go 350 fsb
if i change anything in bios other than overclocking options
it still double restarts, double restarts this is bad for hardware
fans on contollers, & water setup, & hard discs & power supplys.

4.the crappy pci-e clips are cheaply made and snap of when trying
to get raid cards out if you have a dual slot graphics card.


its pretty much easy to hit high FSB 425 +.
Memory for this to get is MICRON based, avoid elpida & prommos
with asus 975 boards.

Vcore 1.2875 ACTUAL IS 1.35 this drops to 1.33 under Load
FSB termination = 1.4V best to have it at this problay get away with 1.3
MCH Chipset voltage = 1.6 for upto 425 fsb 1.7 if going above 430 fsb
ICH Chipset voltage = 1.2 you can leave this auto is you like

 

[1dmf]

Well I've tried all the settings shown and my PC won't boot I can not get FSB 400 let alone higher.

I've set everything exactly as shown (except RMS as I don't have this option)

So anyone thinking of getting one of these boards 'expecting' them to hit 400+ don't , because not all of them do!

I have disabled the onboard audio as use an x-fi but never noticed long load times before it was disabled. Annoying thing is it does take a while to detect usb devices attached right at the beginning of booting up.

Who uses firewire anyway these days + havent heard any probs about this but it should be fixed in later bioses

Mine has always shutdown for couple of secs on restarts - was a lot of talk on xtremesystems about this and damage to drives but most people agreed that it wasnt doing any damage as drives always spin up and down anyway.

Asus have always used rubbish clips on pci-e slots - its better to snap them off if you ask me - dfi never used them

As for volts most 975 boards drop a little under load and the asus drops a lot less than most. Depends on bios version as to whether it undervolts or overvolts etc but remember to use high mch volts if using divider or memory just errors in memtest.


The chipsets apparently get fairly hot but mine has always sat at about 25 degrees with volt increases making no difference. I did remove all the heatsinks straight away and put artic silver on them

i said the same thing dude about it wouldn't go over 400fsb
now it can prime happly at 425fsb 1.1 with memory
orthos 5 hr blend and 10hrs stress cpu.
my problem it was failing blend was ram as it wasn't a matched pair
they had diffrent trfc timings


are you sure your chip will do 400fsb on air
why dont you try mulitplyer on 8 or 9 instead of 10

have you tried latest bios?

 

[1dmf]

I've even tried 6 & 7 !!! nothing, my memory is suposed to be a matched pair Team PC6400 3-3-3-8 D9GHM chips so they should do the job shouldn't they ?

i've got the latest bios, but i've now been told that 005 might be beter, i'm beginning to feel it could be my memory playing up - I hope not I spent a small fortune especially on these as they were supose to be the best!

i'll try the 005 bios and see what happens.

 

[james32]

put it all @ stock fsb and run orthos blend
memtest is not good as it passed my ram all day long
but orthos blend found erros in under 5 mins.

 

[1dmf]

I can run Orthos no errors for hours @ 3.33ghz PC8500 - 1000mhz , with 10 x 333 not probs, I just can't get higher FSB and boot let alone have things crash on me

6 x 400 = 2.4 thats less than stock for the CPU and 800mhz memory is stock , it just won't boot!

 

[1dmf]

lol - having said that I tried orthos again ram test only and it failed instantly, I set to stock and tested again it's running ok, but I put my Sythe Karma probe on the heatspreader and their 44c -> that's hot isn't it?

I think I'll RMA the ram, it aint living up to the price tag! and @ any road 400fsb 1:1 is running them @ stock and my PC won't boot, so I think I have to narrow it down to ram, wouldn't you say

 

[james32]

show's screenshots with cpuz of spd tables
with the 2 sticks under (memory slot selection)

 

[1dmf]

hope it helps, what is confusing is the SPD is different to the CAS settings they are sold as for 400mhz

I've tried 3-3-3-8 , 4-4-4-12 , 5-5-5-15/18 and 6-6-6-18

 

[james32]

as you can see your memory is meant to run
3.4.3.9 @ ddr 400 speeds the spd tables dont lie
as this is what manufactures program into them

your ram shows excact same timings as the team extrme pc6400
cas 4.4.4.10 set

 

[1dmf]

So I was robbed then as they were sold as and purchased as PC6400 3-3-3-8

even still , i've even put them to use SPD for timings and it still own't boot @ FSB400 , shall I RMA them regardless, they were sold to me under false pretences, even the packaging said they were 3-3-3-8!

 

[james32]

theres no way that ram will run 3-3-3-8 @ pc6400
unless you give it loads more volts

what voltage do you give them

i looked @ it specifications say's 2.2-2.35V for 3.3.3.8

 

[1dmf]

2.25v in bios and tried 2.3v in bios.

They won't run @ 4-4-4-12 400fsb let alone tighter, I have to assume it's the memory not liking 400 clock speed.

I'm running @ the moment on everything stock and manually set to 3-3-3-8 , it has booted but ocassionaly on boot I get a failed overclock bios error, yet i'm not overclocking?

Edit: I think i'll RMA them and get the cellshock instead, at least I might be able to get 1:1 with them!

 

[ted34]

Take the memory out the equation - put them at 4,4,4,12 @ 2.35v which should be more than enough juice for them to run at 400mhz. Also try other slots on the board (not sure which slots are best for teamxtreme but i remember the asus a8n sli premium that gave me an extra 20mhz on a set of corsair sticks when i changed slots). Also try just running 1 stick and see what happens and last thing i can think is to take cpu out equation - run a divider and keep multi at default, cpu within known fsb limits and run ram high. Make sure mch volts are at 1.8 for this.

 

[1dmf]

run a divider and keep multi at default

How do i do that?

I've tried 4-4-4-12 @ 2.35v I've also tried swapping the slots.

Dram frequency 1st picture ^^^^^^

so you would leave stock 266 for cpu then work the memory onto a divider
mabaye the multi your trying doesnt like your cpu or ram
