ASUS P5B-Deluxe; Problems & Fixes

[JoeBar]

I thought the boot-vmem voltage problem had been fixed with BIOS releases by now...

I haven't heard a similar prob for a long time on a P5B also...

[mrt2]

Man if this actually turns out to be the issue I'm going to be so happy yet so freaking pissed that it was this and didn't have to buy a new board to begin with LOL... I mean usually if something burns out like an nbridge chip or cpu or something you can smell it... and the simple fact that my pc was working fine until a reboot one day should pretty much mean it's not an actual hardware incompatibility issue... Where can I find that list of compatible RAM at for this board?

[Kumakichi]

I thought the boot-vmem voltage problem had been fixed with BIOS releases by now...Well, I guess if your RAM isn't on the approved list, it couldhave problems. But there is also some high-end RAM on the list on the Asus site that needs more than 1.8v to boot.

I'd be willing to bet that our mobo's have pre-07xx bios.

[mrt2]

Yeah my mboard came with like revision .5xx lol

[sluzbenik]

QVL RAM is on the left side of the product page...Actually since it only goes up to DDR2 6400 RAM there isn't anything on there that needs more than 1.8v I think. It hasn't been updated either since I looked at it last August.

So a few days ago I go to my pc only to find out that it had apparently rebooted and stuck

on the windows loading screen. Upon rebooting I get no post, no error beeps, no nothing...

Somehow I just figured it was the North Bridge or a mboard related issue (I have an inverted

motherboard/case and they have issues with heatpipes on most boards). I figured the

Norhbridge probably burned out or stopped. Even power cycling to clear the settings didn't

work... I even took out the battery and cleared the cmos data that way... No Avail. So I

figured it's definately the board. ANYHOW I got a new p5b-deluxe yesterday and replaced the

nbridge cooling with a thermalright HR-05 and the other chips with some ramsinks... my first

boot was just fine, just changed the date in bios and booted to windows. When I got into

windows since it was the same board windows acted like nothing changed. So I proceeded to

update my bios to the 0908 revision like I was using on my previous board. I reboot and now

back in the same boat... the new board won't POST and I haven't even touched the voltage

settings or anything. When I try to boot it does the whole double boot thing that usually

does when you change voltages etc... where it will start up for about a second..power back

down then fully start again. Now heres my dilemma... I could have possibly put my nbridge

cooler on wrong... and the nbridge burned out again possibly (even though I never touched

the stock settings)... Or maybe there is an issue with those particular bios (which doesn't

make sense because I was running that revision for like 3 weeks on the original board before

there were issues.)? Or maybe with this bios revision there is a hardware compatibility

issue? I'm stuck... I need my pc up and running and willing to buy a THIRD board, but I

can't keep going through this. So now I'm thinking which board to buy... ANOTHER p5b-deluxe,

an asus Striker, the new RD600 DFI board... Not sure what to make of this issue and also

what to buy next or how to fix the old board.... What do you guys think? I know there is

alot of information here and alot of questions... any troubleshooting tips or advice about

this board or the possible purchase of a new one would be GREATLY appreciate.

I need a stable board that I can get as close to 500FSB with 1:1 and good timings as

possible... I'm a gamer and this machine is my powerhouse machine so I need a board that's

made for performance, features, and to be pushed with the newest games...

well it happens to me 3 times already....unplug de 24 pins and the 8 pins from the cpu,took off the batterie,one dimm on the yellow slot further from the cpu,and clear cmos all night long.

[mrt2]

Well trying the only one stick of ram seemed to have done the trick for me! =)
Thanks for all your help guys.

In bios under the hard drive options where it says how to run the sata drives... the options are RAID, IDE and ICH8.... what does ICH8 do? Anyone know?

[Alexandrus]

ICH8 is AHCI mode, update your BIOS, since 0711 it doesn't say ICH8 anymore, it says AHCI as it should.

i have overclocked my e6400 to 3.2 Ghz but at post it reports my clock speed to be 16.92GHz !!!!!!!
wtf

windows & cpuz reports the correct speed

anyone else have this ???

[mrt2]

So what is AHCI mode?

that's normal, don't worry about it. it's just stupid incorrect readouts.

[gmcinema]

So what is AHCI mode?

The Advanced Host Controller Interface (AHCI) is a hardware mechanism that allows software to communicate with Serial ATA devices such as host bus adapters which are designed to offer features not offered by Parallel ATA controllers besides higher speeds, like hot-plugging and native command queuing (NCQ). The specification details a system memory structure for computer hardware vendors, in order to transfer data between system memory and the device.

The AHCI protocol was announced by Intel in a May 2003 press release.

Yeah thats why we build computers that can think for us

[mrt2]

Ok maybe I asked the question wrong then... I didn't really need to know WHAT it was... in my head when I typed that I was actually thinking... what are the performance advantages over setting it to IDE in BIOS... Like real world performance... will I actually notice a difference in load times etc...?

[Angelico_Payne]

If u do mutitasking - yes, if u do normal operation - slighty or none.
That is offcourse in theory, u cant know until u make the comparison realtime.

Maybe somemone that has been using IDE and reinstalled to ACHI, can share some info?


So anyway, yesterday I finally got my gpu and mem, so i assembled it, and booted. I was happy as a child, since i was w/o cmp for almost 3 months.

It booted fine, i got into BIOS and set it up and when i pressed save, I almost got a heart attack - computer shutdown like I cut power to it... I could hear my HD head fell as a rock. And then it turned on again by itself fine.

I have read all there is about this board, but until u acctually experiance this, u have no idea how it really feels, esspecially if u have data on disc, or after u did OC.
And then during post i saw that my revision is 0507. Jesus, its even miracle i booted fine.

I can tell u, ASUS makes good boards, but always manages to kill all that hard work and beauty with some little crappy thing that annoys hell out of ppl.

After that I had a mishapp with partition magic, so i spent all night repairing partitions... and then i realized that i forgot my AIO in the firm, so i went to sleep, and will be finally doing the system in about an hour or so.

Piece of advice which most of u probably allready know : Never do anything with computer when u are tired. U will live longer

Next time i write here it will be from my own comp

[idiotekniQues]

if your drives do not support NCQ then i assume there is no benefit to using ACHI mode?

Can't get my CPU lower than 50C idle for some reason... I bought a new board because some other issues and added EXTRA AS5 this time on the chip but no matter what I do, it still stays between 47 to 50C at idle... what could I be doing wrong? Maybe I'm mounting it wrong or something else? There is an issue with the square piece of foam around the backplate of my cooler (Tuniq Tower)
Since it had adhesive on it and stuck to my original board....but I don't really think that piece is THAT important...I got the backplate on just fine and screwed the HSF in as tight as I could without cutting my fingers too much LOL... why in the heck do they make that heatsink so freaking sharp...? LOL
ANYHOW this has actually made me want to try other types of cooling other than air...but I'd rather stick with what I bought than spending more cash...
Suggestions?
OH YEAH this HSF is REALLY hard to get on so in installing it, it does slide around a bit...could that have slid some AS5 onto the side of the IHS possibly or something or what? Any help would be appreciated.

[Alexandrus]

More AS5 can actually increase temps, maybe you should try lapping the base of the cooler and properly installing it again.

Hey guys, which bios are you using on P5B DLX, is there any modded bios which works good on that mobo?

regards

[Tcmjr]

Gosh, I was using only 1gb stick ... So I decided to buy another 1gb today for dual-channel ... cpu-z show as dual channel, so does the bios at boot.
I tough about getting a higher score at PcMark05 , but no increase whatsoever for dual-channel ? WTF ?

[Blackoberst]

I've made some testing with 0804 and 0910 regarding PECI option in CPU Functions.
On 0804 with PECI disabled TAT reports bad temps, one core with negative temps, and the other with positive. -43/~50.
If I enable PECI everything comes back to normal. ~48-50 in idle with TAT and ~35-38 with Asus Probe. On load with Probe goes up to 50.
On 910 with PECI enabled or disabled I get same temps with TAT(idle 50/load 65).
But with ASUS Probe, with PECI disabled the temp remains constantly at 40(idle or load).
After enabling PECI the temp with ASUS Probe is higher than the one reported with 0804 bios, being around 40. Also higher on load, 55C.

Pretty strange, I might say. Hope I haven't done anything wrong or get confused with all those temps.

My C2D is at 3.1Ghz, 1.32 idle, 1.304 load, 1.350 bios.

[Alexandrus]

So what does PECI do afterall ?

[Drager2]

LittleDevil Everyone use the last one (0910 current). There is no any modded bios, cause it inpossible to do it.

Hey, maybe disabling or enabling PECI can hlp with sub zero temps? Cause I remember when it was auto - TAT always reports that CPU temp is +13, but in real it was -17.9(S&M says that) Anyone can try?
