P5B Deluxe - shuts down after saving changes to BIOS?

[sierra_bound]

It is normal on any setting other than "grandma"/stock mode, since the Asus Bios team decided to reboot the clock gen chip to apply those non standard clock setting.

Yep, its bad for PS and HD, but request for fix already submitted and it seems this issue is not in their priority list yet or couldn't be fixed at all, time will tell.

I don't think this is just an Asus thing. Other boards including the Bad Axe will sometimes do it, especially after a strap change in the BIOS. I think it's the chipset.

[aggybong]

I've always noticed it and figured it was normal, but I now fear for the safety of my hard drive

Sierra, you said "sometimes" at the bad axe board, I believe you should have figure out yourself, this mobo does it "everytimes" !

Even after a warm reboot from windows?

[bing]

Yep ! As long they're not in "stock" setting.

Well, when I had a Bad Axe, it did it almost every time because I had a very high overclock. I was discussing this issue with jinu117 about a month ago because if you have a phase change system, the concern was that the compressor would turn off during that temporary shutdown. I got around the problem by just using a seperate PSU for the phase change unit's controller.

This issue has existed from the time the 975X chipset first came out, during the pre-Conroe days.

It happens ALWAYS after 375MHz or so, from what I noticed. Below that, I get smooth restarts and BIOS changes. Also, same shutdown takes place most of the time after vcore or vdimm change, multi adjustment.

As much as I hate it, as others mentioned, this appears to be "normal"... So, yes, Everyone experiences that, without an exception.

[sierra_bound]

I believe the P5WD2-E did the same thing and that board has been around for awhile. The only reason this is suddenly becoming an issue is because there's a huge influx of new Intel users who have probably never experienced the temporary shutdown thing.

People need to keep in mind that a year ago, hardly anyone posted in the Intel section at XS. Now it's the most heavily-viewed section.

Anything below 380mhz fsb using the 1:1 memory strap will be fine. If you go over 380 it does the double restart. It will do the double start below 380 after a shutdown but not on a reboot or reset. I plan on keeping mine at 375 and just holding out for kentsfield. When I get kentsfield I get one with a higher multiplier so I won't be too tempted to try to go over 380 mhz.

Kentsfield is not a high FSB chip like Conroe or Allendale. Only a couple of people have managed to reach 400FSB (including me ). Also, because Kentsfield is essentially an Extreme Edition processor, it doesn't matter what the default multiplier is. On some boards (mainly Asus 975X mobos), you will multipliers up to x20 available.

I tested about half a dozen boards with Kentsfield. Some won't even reach 350FSB. I did 435FSB with the P5B Dlx, but only with one particular BIOS. The latest BIOS has multipliers up to x12, but they don't work. Only 6-10.

All my intel boards for the last few months have had this feature.
I been away from Intel for quite awhile, then came back to the 975X chipset, with the Asus P5WD2-E... and had 2 of those, and both did that.

my DFI 975X does that, and I am on my second one.
my Gigabyte DS3 does it.

and now my Asus P5B-D does it too.
its just a normal thing for this chipset to do.
as long as it boots, I am not worried about it.

[corvus_corax]

That kind of boot it seems to be normal in many Asus boards.

Doesn't this damage the motors in the hard drives?? Can't be good for the PSU either, sudden inrush of current all the time.

I'm surprised no one has experienced damaged HDs due to this.

[camouflage]

Same here with a brandnew P5WDG2-WS PRO.

Should be O.K. - read somewhere that it is typical for 975x chipsets, kind of "secure mode" to avoid BIOS errors.

But it feels horrible..............

[ThorLite]

I have a P5W the restart-shutdown starts at 318MHz FSB bellow that it never happens even if i change everything in BIOS except FSB it will not shutdown for 2-3 seconds.
If i load windows at 315MHz FSB and clockgen even up to 420MHz FSB if i restart in windows it restarts fine with no shutdown.I also use a second PSU for my Prometeia and i have connected my HDDs to the second PSU because i dont want my hard drives destroyed........

[_Eduard_]

my ing arserock conroe-xfire (intel 945p) board restarts FOUR TIMES on a cold boot before finally starting up! at stock! im totally pissed its ruining my hardware! Anyone know of a board that doesnt do this (well for a start, my asrock dual-vsta board doesnt do it, so it is something specific to intel-chipsets)

[camouflage]

Fine - I think I fixed it for the P5WDG2-WS PRO.

Flashed this BIOS here:

http://edu.tchsien.com/CBB/coolaler/...S-PRO-0004.rar

In the MEM menu (chipset) is a new appearance, You can change the read delay now.

Set it to 7 - no COLDBOOT anymore after leaving BIOS.

seems like intels problem rather then the manfacturer.

That is what I am counting on. I will get a kentsfield with a higher multiplier then what my 6400 has. I'll either get 9 or 10 that way I can keep the fsb under 380 and not have to worry about the double restarts. That way I don't put too much stress on my hard drives or my pump. I will be keeping my e6400 at 375 from now on as well. The 3.4ghz I was running is nice but it won't make a bit of difference while I'm gaming or surfing the net. I'll leave the xtreme overclocking to the pro's, and just sit back and admire their work.

It'd certainly annoying, as i get impatient.

The added stress in the HDDs doesn't make me terribly happy either.

But doesn't seem i can avoid it unless i run a very light OC...

Even when overclocking beyond 380FSB???

[rob725]

I'm pretty sure I read somewhere that ASUS does this intentionally for stable overclocking.

[dinos22]

yeah that's normal for Asus P5BD and Gigabyte Ds3...............actually DS3 wasn't as bad as asus

[Bail_w]

man this features drives me completely insane!
