MSI 990FX GD80 CPU Voltage problem

Hello guys, I am new to overclocking and i think i have encountered a problem.
Whenever i try to increase my CPU voltage over 1.37 volts in B2 bios my PC freezes and cant boot up. The GPU fan ramps up for a moment and it sends a signal to the monitor but as soon as the monitor turns on there is no signal and it turns off. This keeps on going over and over until I clear CMOS.
PC Specs.
CPU: AMD Phenom II 945 95w x4 3.0ghz 945 (Deneb) (Waiting for FX8150..)
RAM: Corsair XMS DDRIII 1600Mhz downclocked to 800Mhz
MB: MSI 990FXA GD80 Military Class II AM3+
GPU: ATI Radeon HD 5870 Sapphire CF
GPU: ATI Radeon HD 5870 Asus CF
PSU: Corsair AX850w
Case: Corsair 650D
I don't know if its a problem with the motherboard or the CPU but the reason i post this in MSI forums is because once unboxing the motherboard I've noticed that there were some scratches on the CPU socket. I don't really remember what it was but i thought it nothing serious.
Sorry for my bad english...

how did you correct this problem

MSI 760gm-p33 CPU voltage problem

I have AMD phenom II x2 555 processor. And my problem is that the CPU voltage set as auto in the motherboard bios but it's set as 1.44
and the recommended voltages to my CPU according to AMD is between (0.875-1.40V). That's mean that the maximum voltage for my CPU is 1.40 but it is
set as 1.44 by the motherboard and this could damage my CPU.
I need A solution Please.
Sorry for bad English

You changed processor recently?
What is telling you about the voltage? And, why did you wonder about the voltage?
What RAM memory have you got?
Clear CMOS. Pull power-cable out first.
Thanks for replying fredrik.
I didn't change the anything.
I used CPU-Z to know the voltage & I wonder about the voltage because it's high for my CPU.
I have kingston 2*2G DDR3/1333 1.5v

Msi p45 platinum cpu voltage problems...?????

my system...
msi p45 platinum:bios(1.4v) intel e7300.... ocz 800 mhz ddr2 ram

I m changed in bıos voltage but cpu-z dont looking..
1.34v in bios and 1.2v in cpu-z looking....
not nevertime I don"t did...... what you think about this.....
help me pls...

This is a known v1.4 BIOS Bug. It was fixed in BIOS v1.5b1 and in all BETA Releases that followed. If you don't want to flash a BETA Release, you need to wait for the Release of the official/final v1.5 version.

Problem oc at MSI 990fx-gd80

I decided to overclock my fx 8150 . First attempt and stable at 4.2 with 21x multi and vcore at 1.42v(pretty high) and 45c temp full load. And after that i want to give more like 4.5 but things gone realy bad. I tried first multi at 22.5 and voltage at 1.45v which was the max volt motherboard can give me (pretty wierd) but after booting normal and testing at prime in 10sec it stopped with error.I tried a compination of fsb multi but nothing again the same error. I would give a little more cpu voltage but motherboard doesnt give more than 1.45 ... same tests for 4.4 but nothing also there. Anyone got an idea why cpu voltage is locked so low? I saw people with same board going higher their cpu. I got the latest bios 11.13 and cpu cooler h100.

what's your current bios version?

MSI 990FX GD80 REV2

Hi All recently i sent my MSI GD80 motherboard in for repairs due to faulty PCI-E1 slot. the supplier has informed me that they might have to swoop it out however they only have the REV 1 in stock and the ETA on the REV 2 is 6 weeks. my question is there a difference between the two? i currently the FX 6300 CPU and have been told that the REV 1 doesn't support the FX CPU can this be confirmed? i know its a down grade in a way but 6 weeks on a swoop out under warranty is a long wait.

As far as I know the only difference between the 990FX GD80 and the 990FX GD80 V2 was that the V2 came from the factory with BIOS to support FX CPUs where as the 990FX GD80 originally required a BIOS flash to support the 1st FXs when they came to market. As far as the MBs go they should be the same no matter which one you get. They both needed BIOS update for Vishera as neither one had BIOS to support Vishera when they came to market.
You may need to have the BIOS flashed on the replacement MB to support your CPU but you wont know until you get it, There would be no guarantee that either version of the MB you end up with would support your CPU, you could ask the supplier if they know what version BIOS it has on it. Maybe they could even flash the BIOS to version that supports your CPU.
Basically the downgrade is in name only, MB and hardware on it is the same. Compare the specs, they are exactly the same between the 2 of them.

MOVED: MSI P35 NEO2 FIS voltage problems!!

This topic has been moved to Overclockers & Modding Corner.
https://forum-en.msi.com/index.php?topic=120804.0

same problem with the Neo2 FR (like mine). After quite of bit of researching and testing i reckon that software can not correctly read the vRAM on these MSI boards. I found that Speedfan, Everest, and HardwareMonitor all gave an incorrect reading for my RAM's voltage. Also, if i increased the cpu voltage in the BIOS then the voltage monitoring programs would show an increase in CPU voltage and RAM voltage (even though i had not changed the latter).

CPU Voltage problem...anyone??

hey all, i'm not sure if i have a voltage problem here. should my cpu voltage be at 1.5? it currently runs at 1.35 by default. This is in my Neo4 Platinum board.
Update:
I went to increased the voltage to 1.4 via CPU VID (in bios) however, CPU-Z is showing my voltage as 1.3 which is lower than before. is this correct? Also, watching the voltage readout in CPU-Z i'm noticing the flucuation between 1.36 to 1.408 after setting my CPU VID to 1.4 in bios.. is that ok?
...anyone?

Just using CoreCenter my 12v is a steady 12.14, 5v at 5.05, 3.3 at 3.33 but vcore which should be the steadiest runs between 1.37 and 1.42 with jumps or drops of up to .04. Prior to wed it never made it past 1.39 so maybe it will even itself out at 1.4 +- .02. My other MSI board a KT6V with a 2500 Barton runs a steady 1.63 with a cheaper PSU and a slight oc and the combined price of the 3 is around what I paid for the neo4 board. Maybe I'm expecting to much to think that if you pay more for something the quality should be better.

@home I have a good Volt meter. It cost me more then my mobo. So don't expect the world out the accuricy
Apple that is like comparing apples and oranges there is a big difference in a volt meter which has to handle a large range of voltages and amps and a dedicated chip on a motherboard. The CPU is designed so that at 1.4 volt and a given frequency it gives you a signal strength at the transistor that determines a 1 or 0 bit. "undervolt"only increases the chances of bad data if there is a weak transistor and raising the voltage is only needed if the signal strength drops from the increase in frequency.

MSI P35 NEO2 FIR voltage problems!!

Let's start:
I have MSI P35 NEO2 FIR ,e5200,2 x Geil ultra plus 1066+,as us 2900CT,lcpower 6550g and...rest- not so important for my questions.
1.My problem is next: default voltage values for my RAM is ~2.2-2.4 every time I check in windows (speedfun,sisoft Sandra, everest..)shows me 2.0 or some time even 1.8v . When i change voltage in bios and went to win voltage on RAM is still unchanged (2.0v) .
Same thing happen with NB voltage. But CPU voltage I can change freely with no problem.
When I change fsb(try to overclock) suddenly memory voltage rises how i do not now , but only to 2.35 and no more.
Can anyone help me fix this problem because my memory is not stable at 2.0 or 1.8 sometimes and system crashes?
2.When i change cpu settings from 12.5*200 to (example)10*300 in windows even in system properties see that my current clock is 12.5*300=3750 and not 10*300=3000 like it should be .
Is it bios problem?
My bios version is 1.9.
Thanks!

MSI P67A GD80 (B3) mic problem

gonna post machine first and then get to the point
Mobo: MSI P67A GD80 (B3)
RAM: Apacer 4GBx2 1333mhz
CPU: Intel Core I5 2500
GFX: 2x SLI MSI 560GTX Twin Frozr II OC edition
PSU: Cougar CM1000
Headset: Razer Piranha
Speakers: Logitech X530 5.1
Keyboard: Logtech G110
OS: Windows 7 64 Bit Ultimate v.7200
Every time i try to use the rear port on my motherboard for my Mic the sound volume is VERY low. I've checked all my settings and mic volume is maxed out so i have to resort to use the mic port on my Logitech G110 keyboard which works fine so there's nothing wrong with the mic itself, I'am pretty sure this is Windows issue and yes i know this should probably be posted on some Microsoft forum but I've tried that to no avail just trying to get MSI's point of view of the issue I've uninstalled and re installed my sound card drivers and download the latest ones which came out this month which also don't help the problem. Is anyone else experiencing a similar issue?
Any help would be appreciated

got a cheapo Logitech headset from work to test and it seems to work now so it seems that my old headset is the problem weird thing is that i still worked in keyboard but not my motherboard slot its probably the wiring on my razer headset. Thanks for you help anyways jack

MSI 990FX-GD80 memory issues

just recently purchased the 990fx-gd80 and all i have had is issues with the ram.
i have been testing constantly for 2 days now and come to the conclusion the ram i have bought isnt supported at all
i can only achieve DDR3-1333Mhz 8-9-8-22, because if i take it any higher windows puts 2063mb of the ram into "hardware reserved" in resource monitor.
i have tried all the fixes in the world like msconfig boot options, DDR voltages, manual timings, memory remapping options and basically everything else!
i have the full 4GB running in windows now but i cant achieve the rated 1600mhz speed set by the manufacture.
i have attached the SPD information of the ram below.

op, mods, admins, MSI staff - you can view the issue by:
1) flash bios .1 off the web site and clear cmos for good behaviour.
2) put sticks in for dual channel sockets.
3) select ddr3-1600, save and exit.
4) memtest (latest one) from a boot disk.
5) test reports (and so will windows) 64bit DC with a stick reserved and you will get through with no errors. windows will also boot but your 2nd stick won't be available.
6) reboot.
7) change memory to unganged for 128bit SC and the board will fail to post with a code of 54.
8) clear cmos back to defaults to get back in.
9) flash *any* other bios *after* version .1 (either .2 off the site - or one of the b3x betas from places), keep the sticks in the same sockets and run memtest again at 1600. you will find it hangs the *second* it tries to access the 2nd stick and if you can get into windows - you will find that you are in 64bit SC mode (even though you haven't touched the sticks) and still 1 stick will be reserved.
MSI STAFF, MODS, WHOEVER... on certain chips... this board doesn't use/initialise/work with/switch on half of the IMC. it's not an OC issue. it's not a 1600 issue. it's not a XMP issue. it's having a rubbish UEFI bios that was written by drunken chimpanzees and all you're doing by making your customers go round in circles is make us all buy another brand of product in the future.
OP - you've the same issue as me. my board'll be going back to the shop for a refund after the UK holiday I think. support have had my ticket in for 3 weeks. first they sent me a scan of the instruction book and 2 weeks later said they will get a engineer to look at it. 150GBP for 3 weeks downtime. bargain.

MSI 970 GAMING CPU Voltage

Hello all.
I have a problem with my CPU voltage and OC'ing.
First little backround, I did have Gigabyte GA-ma770-UD3 (rev2.1) before i upgraded to MSI 970 Gaming. I was able to OC The 1600T CPU to 4000MHz with 1.55V and it was prime95 stable 24h, but i kept CPU clock at 3800MHz 1.45V prime95 stable 24h as i didnt want to kill my CPU beacause of high voltage, oh and was using 4x1gb DDR2 900MHz.
Sooo. Now i've been playing with this new mobo, and im little confused. My CPU VCORE is 1.392V, voltage setting set AUTO on BIOS, my previous build with gigabyte mobo had this set to 1.350V on AUTO in BIOS.
Could the "wrong voltage" value be because of my prosessor is "AMD Processor Model Unknown" in CPU-Z and BIOS says the same.
Also the whole overclocking is not fun anymore, seems that i cant achieve any higher STABLE OC than 3700MHz and that takes too much voltage, around 1.5V.
I really feel that there is something wrong with the mobo or the bios, as i have tried OC'ing with my old motherboard and i can OC my CPU well better than with my current MSI 970 Gaming. And i think this mobo should do better or atleast equal to my old mobo.

you have to make sure that your CPU could be properly recognize in the bios first

K9n diamond cpu voltage problem

got this board 3 to 4 monthes ago no problems great board. ive notice that my cpu voltage is running at 1.39 to 1.41 volts.the athlon 64 3800 cpu volt rang is 1.35 to 1.40 . when i go to the bios i cant find where to set my volts ive tryed everything in the bios. any help or suggestions please and thank u also my memory is at 1.90 need to set at 2.o

Cpu voltage problem

I cant seem to my cpu voltage over 0.630 v it says on the right "this is the offset to adjust the current cpu voltage.Read the realtime cpu voltage in cpu vcore in the h/w moniter. " so i have to do cpu voltage calculations? How much cpu vcore is 0.010 voltage then im confused
Btw i have a x58a gd45 mobo with ami 2.52 bios

The self contained water cooling solutions are no better than a high end air cooler. I have the H70 and used that on my 2600K. The results were never spectacular and I must have changed the paste more than 4 times, tried different fans etc,. Then I installed a Noctua Air Cooler and found that the temps are slightly lower than with the H70, but the noise was so much less. Those 140mm fans on the air cooler are much quieter than the wind noise created by forcing air through those tightly packed radiator fins. Just some food for thought.
There are some excellent air coolers that cost a lot less than the water cooled solutions and perform as well; the Zalman that Henry mentioned and that HU16E uses, is one of the better options out there.
Here is a nice site that does extensive cooler testing. http://www.frostytech.com/top5heatsinks.cfm

MSI Z68-GD80 (G3) Big Problems

So I have gotten my MSI Z68-GD80 (G3) Motherboard 1050 Watt powersupply from corsair 16GB of ram Corsair Vengence GTX 580 Twin Frozr II 2600K and a H80. At Stock Speeds My computer just frezzes in till i reset my computer or it automatically restarts and i have been losing Work Info because of this problem. In Prime 95 i ran it for a hour no Errors or anything. When i Enable OC genie Prime 95 Crashed in 30 minutes my computer freezes loud noise comes out of my headphones. Then i try pressing reset button no respond so i had to turn of my powersupply. btw my highest temp on the core was 55C. This usally happenes when i play games like: MW2,WAW,Crossfire,CSS,TF2,and so On. Btw im on the latest UEFI and drivers i believe since i used the LiveUpdate.
If i have to RMA this Board can I drop it off at MSI Viking Road Richmond I Live Near there.

Have you tried it without OC Genie ? What are the results ? Which BIOS are you using ?
Only insert one memory module. Do a CMOS clear >>Clear CMOS Guide<< Remove the battery for a while.
Ensure that EuP2013, Spread Spectrum and XMP are disabled.
Retest with only one memory module.
