FYI:

P5WDH Motherboard Temperature Sensor location - (circled in red)

many many thanks for that

Just go to Start -> Control Panel -> Network Connections and doubleclick on your Network Connections' icon.
Check out the "Support" tab, if "Address Type" says "Assigned by DHCP" then you're using your router's DHCP Server ( perhaps the DHCP IP Lease is 1 hour, so it might be releasing the IP every hour ).

If you're using DHCP, try setting the IPs manually, and check if your issue insists.

Thanks!
It is DHCP. I have it set at 0 in my router config. I'll try setting it up manually.

I'm looking at getting a Thermalright HR-05-SLI, Northbridge SLI Heatsink to improve the cooling for the NB and a HR-05, Northbridge Heatsink for the SB.

On this board the NB heatsink is connected to another heatsink cooling some chips behind the CPU, what chips are these, how can I replace the heatsinks on these and with what ?

I also have a Thermalright Ultra-120, CPU Heatpipe Heatsink, so does anybody else have this and a HR-05-SLI ? i.e will it fit ?

yes it will but it will be too close on your video card

my tuniq just arrived

goodbye ultra 120

i need your help to do bios updrade for the first time, i an using win Vista
i shoude id do it ?

If you never upgraded your BIOS before, it is better to read your motherboard manual, there it will tell you how to do it. There is a very easy to use tool: the AsusUpdate. This program is on your Asus disc. But again, read a lot before you try.
It is better you look for another forum to help you out if you want step-by-step advice. This forum will not help you on any issue that can be classified as "beginners stuff", you will be ignored.

Good luck,

Hi, my replacement motherboard has been shipped by OC, can't complain about that turn around. I wonder what rev. it will be as my old one was 1.02...

You've recently changed your recommended BIOS 1901 into version 1602.
Please explain why.

I second that. Why???

[crazyea]

I second that. Why???

I was wondering as well......

[scaramonga]

Simple I would guess..........1901 is s h ! t and has no improvements over any version above 1506 really?

But some feel they must flash when they see new 'numbers' LOL

And how does it overclock with the 4 dimms??

[infrared]

The board seems to max out about 30mhz lower than with 2 dimms installed

A little more vmch fixes this

I've been using 4 dimms from the start and see no difference between 2 and 4 dimms while overclocking. But my cpu isn't very good, only 3.8 max on e6700.
My qx6700 should arrive within 7 days and i'll test on the p5w dh, but will probably swap to commando.

3.6 on the e6700 with p5w dh 100% stable 24/7 (i do bf2 a lot!)

Well, 1901 supports the 1333 bootstrap according to Asus.....I wouldn't call that "no improvements"

[lawrywild]

1901 isn't crap, and I don't know why people have problems with it..

But since everyone seems to blame me for flashing to 1901 because I apparently made them flash to 1901 (f off out of my thread if you think that was my fault tbh)

1602 is official, didn't have problems so I just put that..

D**n right. It's completely up to the individuals to follow your advice or not. Even if i killed my motherboard while following your advice i wouldn't be angry with you, because at the end of the day i would have been the one that did it.

Some people should really grow up and stop blaming others for their f'k-ups.

1902 is fine, and it is still possible to backflash to a previous one, so everyone should stop whining and get on with it!

EDIT:

If anything, people should be thanking you lawrywild, for this excellent resource you've provided to all of us!

So thanks!

[cuke2u]

Hi, I support you there lawrywild, people seem to b**ch and moan about something THEY did to there MB. I'm using 2001, BTW, and like the previous ones I have no issues with it...

[crazyea]

I tried 1601, 1701, 1801, 1901.

1901 is the only bios for me, that has allowed 400fsb 1:1 orthos stable for 8 hours on both cpu stress and mem stress. So I'm staying with it. If my computer blows up in then next 5 mins, there is no one to blame but myself. As always o/c at you own risk not Lawry's.

[crazyea]

BTW, for reference, the others dropped out after only 6 mins.

[FabricioGS]

1901 seems very stable for me too. Don´t know why all that complains.

No offense meant

Some issues...

1) Locked upwards multipliers ( ratios ) with Extreme Edition CPUs. Why did I buy a E.E. CPU dear Asus ? Because I want/needed the upwards multipliers maybe ? :P

2) Flashing back to another BIOS version can only be done successfully with AFUDOS v2.11 &/or AFUDOS v2.17 only.

3) No real change, like adding tRD & tRFC...

Have more stuff, but I consider posting all these stuff a waste of time

Has anyone of you unable to use EE multipliers complained to Asus? Have you written about tRD, tRFC or even AFUDOS issues? Thank you for sharing your experience.

1901 was the worst bios to date for me. I'm content with 1707 for now. I'm with BenchZowner in wishing that Asus would actually listen to it's customers regarding this board. It's totally absurd that they can't/won't fix the upward multi's and add trd and trfc.

I wish I'd known that I wouldn't be able to see my ram's full potential with this board before I bought it. I would have either bought cheaper ram or most likely bought a different board. It's silly that a simple fix in the bios could fix this, but I guess Asus doesn't have time for their customers.

I can make them one promise. If this is never fixed, my next board will certainly not be an asus.
