Vcore reading on A7V266-E (BIOS vs. Probe 2.0)

[compuser]

I am getting 2 different readings from bios and from the asus utility within windows for the core voltage. (bios 1006b (?) - latest bios)

BIOS HW monitor = ~1.74v
Probe utility = ~1.84v

(no overclocking). also, the case fan(s) monitoring is just not available (only CPU fan can be monitored). from bios and windows.

anyone have this problem or know a work-around?

Download MBM5 to get a more precise reading. Asus probe is screwy.

More often than not, Asus tends to ajck up the vcore by 0.03-0.05 V from the rated Vcore that you set. They claim that this will improve the stability which it does.

i have the same motherboard, my probe also reads the voltage at 1.84 no matter what voltage i changed to in the bios
the bios hw monitor is a more accurate one.

thanks pillage2001 and imdmn04, that should clarify the confusion. but then is 1.75v core voltage the correct voltage or does this need to be bumped up to 1.8 or something for 1800+? my system keeps freezing right now with the current voltage settings.

while investigating into this problem, i just noticed another thing: with this mb, you can't have the suspend feature in win2k?! please correct me if i am wrong but the APM tab shows up in power control options in windows. upon reading the helpfile on that, it said that APM will appear whenever the system doesn't have a ACPI compliant bios. even the ASUS manual (sect. 4.5/p.69) makes a note about the need to install this feature. as a matter of fact, in the past, when i was using the 1004B (shipped) bios to pilot test win2k etc., it had crashed during bootup/install etc. with a message similar to that: something to the effect of system not having an ACPI compliant bios.

i am guessing this has to do with some bios power settings. can anyone confirm this problem? it looks like the bios options don't quite match with system behavior at os level. (any place where there is update info about the latest bios which seems to have a slightly different option-set?)

Comp is freezing?? What temperature are you getting??
1.75v is where you should keep the voltage at.

As for the win2k problem. I'm not really sure about it. I'm running Win98SE.

case ~ 22c
cpu ~ 51-52

it could be software although i just reinstalled 2k last night. when playing dvds (power dvd or ati's dvd player) or when trying to setup tv for ati card or even on random events at times; the system freezes up.

i think the settings in bios could be the culprit. i have mushkin value ram @ 2.5-3-3. i know it can't take max settings but currently it detects these settings correctly using spd. sandra 2002 scores for cpu and memory benchmark are all above their reference via systems so system seems to be pretty good in terms of performance but i can't explain the hangups till i know what bios settings for cpu/fsb/memory to use.

update: MBM5 also reports 1.84v for vcore! this is interesting and annoying if it is true.

anyone else with this reading? so NOW, what is the optimal vcore to set in bios, if this is the same in mbm 5?

 

[Imdmn04]

MBM5 and the probe reads from the same source, nothing wrong with the software, asus is known for faulty readings

Mine reports aboutt he same as your's too. It's alright. Set it to 1.75V in your bios and you should be okie. You computer is still freezing??

 

[compuser]

hmm... vcore = 1.75v - set it and forget it! i get it. it's as easy as set it and forget it. (sound familiar?)

sorry pillage2001, didn't get out from work till late evenings all this week. yes, the computer still freezes, and at this point it appears to be due to the drivers for cmedia sound card - either drivers or drivers or irq issues. i don't see any conflicts in win2k and no exclaimation marks in device manager either. the moment i put in a ct4810 SB sound card (antique), it (with crackly noise sound, stops freezing and works great through dvd playing etc). otherwise, it just starts freesing and looping part of the last sound in buffer (?) over and over as it's frozen. this happens randomly when sound is involved... be it a simple wave file on a web page or be it watching a divix or divd movie/file.

anyone else have any problems with cmedia sound/drivers with this mb?! also, does ANYONE know what in the world asus is trying to say in their manual about the irq settings and telling which slots are shared in intA, intB, intC and intD configurations or something to that effect? i guess they are implying something about possible slots to insert cards for proper functionality but i thought this was done in win2k automatically and it ignored bios settings etc.
