Voltage Question in Core Center/Bios

Just the other day, core center and bios started dislaying my voltages differently. This was right when my temps seemed to drastically increase as well.
My voltages before were always stable, especially the 12v line, it was always 12.12v, now its reading at a pretty constant 11.76-11.82v, the 3.3v line is reading at 3.31-3.46v, and the 5v line is reading at 4.97-5.05v.
I hooked up a multimeter to the 12v rail, and it read 12.12 constant.. I didnt hook it up to the powercord running into the mobo, but it seems like they will all read the same.
Could a dying power supply contribute to a huge heat increasement on the cpu and system temp?.. Im talking a good 15c increase.

ditch CoreCenter, it's buggy! Don't use it as it's buggy until it could screw up the overclocking settings and kill your system. MSI just didn't do a good job on Corecenter!

Having trouble with voltage alarm in core center

I hadn't used this comp for about a year, just put it back together and added the kingston ram to it that a buddy gave to me. Just found Core Center online and installed it. The problem i'm having is that the alarm is going crazy. Don't have alot of experience overclocking, and i'm not actaually trying to at all. I've been having programs close and games freeze up because of overheating. This is what I see when I look at the core center.
on the left
1.39 v
Vcore
2.72-82 v (flashing red)
3.3V
4.97 v
+5v
11.84-90v
+12V
If I open the tab, the FBS says 200mhz and is flashing blue to black
doesn't look like i'm having any problems with cpu temp. 35 'C
Any help would be appreciated.
Thanks

do you know how to enter into bios if so then click on default save and exit then see what happens, somehow it looks the voltage for memory has been set 2.7 or 2.8 volt which is too high it should be 1.8 or 2.5 volt
Yea its at 2.5 i beleive. I reset everything to default, and it has been since i put everything back together. Before i had core center installed it was crashing guild wars, and wow consistantly because of overheating. I'll unistall core center and get a monitering app instead.

Newbie question on Core Center

When i bring my FSB up in Core Center manually
(not using the auto button) the vcore doesn't change and
my system runs unstable is there a way i can bring it up
or is core center supposed to bring the vcore voltage up automatically?

When you use corecenter to overclock, The auto overclock feature will turn up your FSB, but it wont touch the VCORE. you have to adjust that in the bios.Or you can do it yourself on corecenter. When I tried to overclock using core center, it would overclock on the desktop but it would not be overclocked in the bios. I would reccomend that you use A program called clockgen in conjunction with speed fan. clock gen will allow you to overclock from your desktop and even set the PCI/AGP settings independantly of the FSB. Speed fan wil allow you to adjust you fans to get maximum airflow and it will allow you to keep an eye on temps as well. get rid of corecenter

Core center doesn't afect bios

when I change the FSB,vcore,memory voltage or AGP voltage in the core center it doesn't change in the bios, is there anything I can do to fix it?

No, the two are seperate things, bios is hardware overclocking but corecenter is software overclocking, use bios for best results when you overclock.

875P Core Center FSB 200?

I apologize if this is a stupid question, but Core Center doesn't exactly come with a help file. I have the 875P mobo, 1 gig Kingston PC3200 CL3 in slots 1 & 3, Intel 2.8 cpu with 800 mhz fsb. My question is that when I open Core Center and pull out the left tab, it says the FSB is running at 200 mhz. Can this be right, or am I just missing something. I do remember that the bios recognized the memory as DDR400, so everything should be ok? Could I have something set up incorrectly?

You're running 800 (200 times 4 :D

Believe Core Center or BIOS voltage?

I have a K8N Neo2 Platinum board (bios 1.1). Does anyone know if I should trust the 12 volt reading from the BIOS hardware monitor or the MSI core center utility.
I have a brand new power supply (Enermax EG465P-VE FCA).
I am getting the following readings for the 12 volts:
BIOS READING
11.97 -12.03 volts
CORE CENTER READING
11.61-11.91 volts
I have been experiencing some stuttering with my new eVGA graphics card and the tech support thought I the power supply might be the issue since it is sensitive to the 12 Volt rail. They were not sure which voltage reading is correct. Unfortunately, I do not have a volt meter to probe inside. Could it be that once windows loads up, it activates more devices causing a voltage drop of some sort?
Any help is appreciated.

The BIOS readings are almost certainly more accurate.
How many amps does your PSU have on 12V? If 24+, then it's unlikely to be that - your voltages look well within spec.
Graphic stuttering can also be caused by several other things, including drivers, AGP fast writes to name a couple.
A slight voltage drop is normal with more devices, but a good PSU should regulate itself to keep within spec.
Edit: Just checked, and your PSU is 20A on 12V, which is "borderline OK", depending on who you ask
I'd try investigating other possibilities before you blame the PSU though.

Question, NB fan in Core Center

Hi,
I have this question. In Core Center I have N/A in NB TEMP and 5443rpm in NB Fan Speed. Is this normal or there is something wrong?
I tried to find it in other topics but didnt find this answer.
Thanx

Hi,
its a K8N Neo2.
MSI should have tested this, meaning, I think its wrong somewhere in my system.
Anyone recognize this problem? I have looked in bios and dont really know all features in there, but with the users guide I have excluded some options.

Core Center showing voltage spikes on the +3.3

I wanna thank you guys for helping me with my various issues this past week. Making sure my new PC is running smoothly is of utmost importance to me, so please excuse me if I seem to be posting a lot lately
I have Core Center running in the background all the time and when it pops up to inform me of an issue, it's usually highlighted the 3.3V value when, I'm assuming, it's too high (or higher than whatever value it has set as the warning limit). It's shown it as 3.78v up to 3.89v sometimes. Is this bad? I haven't adjusted any voltage settings in BIOS or in Core Center because I have no idea how changes to that effect performance. Please let me know if i should be concerned or if I should adjust my voltage settings in some certain way. System specs in the sig.
Thanks,
Eloora

ok, weird....
Bios shows readings for these
Vcore
+5v
+12v
-5v
-12v
Battery
+5v SB
BUT... no reading on the 3.3v... The thing I noticed was the reading for the Battery is 3.331v
Is that what I was looking for?

FSB differs in core center and BIOS...

I know my FSB is set to 200 (the default value) but on CoreCEnter (lattest version) it shows 203... I'm not in a mood to make OC before getting rid of this stock cooler (but that will not be for now) so I wanted to put FSB at 200, I know the differecen isn't much and the system is runnin fine but I simply don't want it...
I have 865PE Neo2-LS and I've disabled DOT in the BIOS (1.5). Do you know what's the problem?
By the way, I just clicked "default" on core center, on the fsb and voltages menu and the CPU just locked-up and a loud sound like PPIIIIIIIIIIIIII wouldn't stop... I rebooted and worked fine but what's the problem?

What you are seeing is the dynamic overclocking feature. If your Frequency setting is set to anything other than "disabled" Core Center will attempt to find an appropriate clock setting for you, based on processor demand and processor temp.
I prefer this to traditional overcocking because it only "kicks in" when I need it.

975XPUE Dual Core Center 5V voltage readout

Hello, I realize everyone unanimously agrees that Dual Core Center should be avoided. However I have a question about the voltage readouts it provides.
On my machine, DCC 5V readout has always reported 2.6x V, quite a drop from 5V. 3.3V reads out 3.31 V and 12V reads 12.20 V. System is running stable despite the weird 5V level. Everything runs just fine. Don't know if this is a false reading, or a true but acceptable reading, or just DCC bug.
Can someone please clarify what the MB 5V reading is referring to. I always assumed this was from the 5V pin on the JPWR molex connector for PCI-E slots. My video card is Sapphire X1950PRO 512 with power from 6pin PCI-E power. I just assumed the molex power wasn't necessary but I have it connected anyway, and so this caused the 5V reading to be low.
Also, I have all 8 pins for the JPW ATX 12V connector attached. PSU has 4+4 connector but I figured just plug everything in if it's available.
MSI 975X PUE (Limited Edition)
E6600 @ 3.07GHz default voltage (343 FSB)
OCZ Platinum Rev 2 2GB @2V 5-5-5-15
Sapphire X1950PRO 512MB
Thermaltake 750W (Modular) w/ 4 12V rails @18A
Thanks!

Thanks all for replies. Svenomous, I'd like to try your tip but dont have a multimeter
I'm not worried that the 5V rail on my PSU is bad. Like Maesus mentioned, that should cause all sorts of issues if my 5V was really pushing 2.6V.
Was just curious what part of the MB dualcore center takes the 5V readout from. If it's from the 5V pins on the 24 pin ATX, then the computer shouldn't even boot. I guessed it was from the PCI-E molex connector and that the MB wasn't drawing the full 5V for whatever reason. All other devices (fans, drives, etc) on molex power seem to run fine.
Was just hoping someone had a definite answer. If I snag a volt tester, I'll follow up with true 5V rail levels. Thanks

Core Center Question ?

hello guys,
i wanted to know about corecell feature and and core center i am using latest version now and my CPU fan is usually at 4440 RPM even with gaming but my system temperature increases from 43-47 usually when gaming ? is this ok and my CPU temperature is 51C because its Prescott and i cannot do anything about it ? i wanted to know does corecell protect our computer from electric shock, overheating without Core Center or it would not without core center becasue the first time after installing windows xp service pack 1 (clean installation) i hear loud noise usually the CPU fan is on full speed but as soon as i installed the latest version of Core Center it adjusts it automatically and quietly and should i change my CPU priority for Core Center as maximum does that do any thing and i wanted to know i have DDR 400 Mhz but in bios it says DDR 333 because i have 533 FSB CPU is that right ? well does that mean i wasted my money on this or does that mean an upgrade to FSB 800 will make that better.

well, your MSI P4 mobo is your friend, because it shuts the system down, when the CPU is about to overheat. and the function "spread spectrum" helps preventing all static issues. but you should disable it, when you overclock. at least its recommended that way in the manual.
your temps seem fine to me, and they look even better because you have a Prescott.
dont change any settings in corecenter. everything is just fine there. i think it reports the temps a little higher than they actually are, but thats just my two cents. but 4400RPM is really fast! my CPU fan isnt reported to be faster than 2800 at most. still enough for my CPU.
no dude, everything is fine with your system. DDR400 memory goes in sync with FSB800 CPUs, such as the northy c versions.

BIOS/Core Center Temps

I'm slowly (not much available time) bringing my new KT6 Delta-FIS2R up. I have noticed that the Core Center CPU temp readout is 4-5 degrees C above the same item in the PC Health Section of the Bios. Because of the variety of Core Center problems that I see people writing in here forum with, I suspect that the Core Center is the monitor that's out of sync. Irregardless, is there a way to bring these two sources into agreement?

Core Center, as well as PC Alert, reads about 4-5C higher than the real temp. Use Speedfan instead, much more accurate, and takes less space.

Core Center Problems & General Questions added

On boot up after installing core center on my PC, I get warning messages telling me that core center doesnt have the correct drivers installed, and that core center is not compatable with my motherboard.
I just bought a MSI K8N Neo4-F ... any suggestions? This doesn't seem to be a common problem and I can't get any answers anywhere :(

After the proper bios adjustments and correct settings i can use corecenter to reach the maximium overclocking setting for this tool.
In bios i do have to set vcore at 1.45 and HT at 4x , disable agressive timings.
This way will lead to a fsb of 222, for my memory also without changing the timings leading to a 6600 score in sandra for memory.
My cpu will clock 2666 then.
Also i have to overvolt through corecenter for cpu and memory,both maxed out giving 2.85 for mem and 1.58 for vcore total.
Now i'm not running this since i don't need the extra heat and my games don't require it either,yet.
And i can run my cpu higher also,but that's not the issue.
It's a way to see with which settings you get more performance without messing up the bios.
Finding your way through it you can then set it in bios and forget about corecenter.
See it as a first step,because after that you can adjust memory timings to get more fsb over the 200mhz. thus finding a balanced setting that will give the most speed,because setting timings too loose will not always result in faster performance even if you can clock the mem higher.
Finally,you can also use clockgen to find your limits.This tool let me set the multiplier also to max out the cpu without compromising the memory.Also keep in mind that different cpu cores will give different results,you can't compare settings with different hardware after all.The venice core is a nice cpu for adjusting fsb settings which is for me a simple multiplier,also the memory divider on my board let me set a very high fsb if needed.Again,this is now a simple multiplier,it means nothing if i have it set at 230 or 340,i only have to bring down the cpu multiplier then to stay in spec and use the proper mem divider.

Core center work whit 1.4 bios?

please
why do not work core center whit bios 1.4...

it works i just checked it try uninstalling the core center and reinstall it

Core Center Voltages

I Installed the new version of Core Center 1.7.1.0 and I noticed that now my +12V line is always under 12v (11.80/11.90) . Before it was always between 12.20 and 12.50 . The BIOS values also correspond to the old Core Center versions. I have a Q-TEK 550W that never gave me problems in OC.
So who is right? BIOS or Core Center?

I'm not suprised if you have a Q-Tec PSU that gave you horrifying readings.
This will happen if you have added more hardware that requires power from the +12v rail to your system as Q-Tec PSU are not very trustable.
