ASUS P5B-Deluxe; Problems & Fixes

[Roger_D25]

Here's a couple screenies after vdroop mod which were not possible beforehand without increaseing voltage upwards of 1.4625v! If I had set BIOS to 1.45v (BIOS) before mod Orthos would crap out within 2hrs at both of the following settings, now their pretty much 100% stable!





*I do have the active screen of Orthos right before I hit "Stop", just incase anyone was curious!

[dnottis]

Yea, pencil mod rocks hard. 1.375v in bios gets me 1.38 loaded LOL. Before load would drop to 1.34v, sometimes 1.328v. After mod when I load it actually jumps up a touch.

[ziddey]

wow, that's not even too bad. before mod, i was setting 1.425 for 1.30 under load.

[Roger_D25]

Yeah this board certainly had the worst droop that I had ever seen before! I know alot of people have brought this up before, but wouldn't something like this come up during the testing phase of bringing a new product to market (Back when the P5B-Deluxe first got released)? This is pretty serious and could/has caused many issues over the years? Well I'm just curios if there are some real reasons behind it?

[ziddey]

it doesn't seem like a big deal, as long as it doesn't droop too much running stock at stock set volts.

Help anyone - I have a SATA drive on the Intel ports disappearing once in a while after the computer has been shut down or in sleep mode. My boot drive is also on the Intel ports and it is not disappearing. I switched ports and the problem went away for a couple of days, but just occurred again. Maybe it's some sleep mode Windows screw-up that's causing the drive not to be woken back up?

BTW, I am not overclocked right now. It started getting hot a week ago and I decided to see how happy I was saving electricity...

[iadstudio]

Sounds like a windows or bios problem.

Mine does this also, but much preferable to the droop. At 1.4625 in bios, I would be all the way down to 1.39 at load. It's nice to be able to set voltage in bios and actually have it be at that setting.

Well someone probe it? i don't what to do...
I'm runing e4300 so what i must to do?

vdroop...

Why all the fuss? Does the voltage wander or something, causing random crashes? Wouldn't that be a bigger problem? Does it wander less after the pencil mod?

I'm not sure why you would be able to get a higher overclock with this pencil mod, as 'actual' voltages are the same. Can anybody explain this to me please?

[Blackoberst]

Can someone download de bios file and atach it here?
The link is not working for me. Thx!

Re-read some of the posts.

My own experience.

Before Pencil mod - BIOS 1.4v, idle 1.36 - load 1.34v
After Pencil mod - BIOS 1.4v, idle 1.402v - load 1.412v

There is a drop in voltages, it causes crashes and orthos to die because, there is droop. Once modded there is less resistance and less droop.

[Roger_D25]

You bring up a good point Psyire but having a more stable VCORE can help with overclocking because you don't have to estimate where your VCORE will be when CPU is under load so you don't have to compensate when setting VCORE in BIOS! Plus the voltage droop isn't linear so it's quite difficult to know right where it will be once under load. Plus there are many people who don't have access to a DMM and won't have any idea what their CPU voltage actually is under load (since the BIOS and monitoring programs all say something different)! Granted your CPU overclock shouldn't change in theory because as you say "the actual CPU voltage is the same" but in practice that is not the case.

[Psyire]

Alright, thanks for clearing that up for me. Makes much more sense now...

E6600, P5B-Deluxe here

For some of these settings I don't know what to put, so I just went with Auto. But I'd like to know if I should leave them at auto or set them to something (and if so, what).

And also for the settings that I actually did put in a value, are they correct?

AI Tuning --> Manual
CPU Frequency --> 333
DRAM Frequency --> DDR2-667MHz
PCI Express Frequency --> 100
PCI Clock Synchronous Mode --> 33.33MHz
Spread Spectrum --> Disabled
Memory Voltage --> 2.25V
CPU VCore Voltage --> 1.4000V
FSB Termination Voltage --> 1.400V
NB VCore --> Auto
SB Vcore (SATA, PCIE) --> Auto
ICH Chipest Voltage -- Auto

THANKS

If i'm not mistaken, you might want to back your fsb down to 332 so the mobo doesn't switch over to the 1333 strap. Personally, if I had your processor I'd go for at least 360-370 fsb.

[bloodandsoil]

Well I'd certainly appreciate feedback about the strap issue. Don't know anything about that.

I may increase FSB later on, but for now I just want to shoot for a mild overclock and run it that way for awhile.

[ziddey]

it won't switch strap until 400.

I'd much rather try and run 8x400 1:1 with ram for maximum performance on 1066 strap on that board.

[Leeghoofd]

yep strap starts above 400Mhz

hy guys
where I can download the SoundMAX Audio Driver v5.10.01.6110 for win xp 32bit?
the asus' server is too busy

Nothing much exiting there. I'll wait for the next one, unless someone finds some more info on this update.

I'm at 8x400 since a few days (stable up to now) so I'm happy.
