990FXA GD65 CPU voltage reading

Hi, I Have an MSI 990FXA GD65 with an AMD FX 6100 cpu.
I have been struggling with this board for a while trying to match the voltage I set in the bios to the readings I am getting from CPU-Z and HWMonitor.
at default with CPU voltage set to auto in the bios cpu-Z and HWMonitor show 1.32v at idle and about 1.30v under load with P95, if I set the cpu voltage to 1.4 in bios they show about 1.48 at idle and 1.44 under load.
What puzzles me is that my CPU needs 1.4v in bios to run at 4.2 ghz, this seems to match what a lot of other people are getting with this CPU but if I am to trust CPU-Z's readings then I am needing 1.44v so should I be trusting what I set in the Bios or should I go with CPU-Z and face that I need a lot of volts to run stable and 4.2ghz is as far as I can go.
I also seem to have very low temperatures for running such high voltages, if it's really at 1.48v then surely it should be getting hotter than 46 degrees running P95 even with a corsair H80. Temps were even lower with a thor's hammer in push/pull on there.
For some reason I cannot run MSI ControlCentre in windows 8.1 so I have no idea what that will tell me.
So just joined up here to see if anybody else has the same issue and can give me some advice.
Thanks,

I have the sunbeam twister 120, and it's AMAZING! The fans on it rotate in different directions making the airflow VERY quiet even at 3k RPM. It's a dual fan push pull with 3 DirectCU Healpipes, and an amazingly smooth base. I purchased mine for just under 30 bucks from Newegg (discontinued on their site) and it allows me to push my AMD Athlon ii X4 640 (3.0Ghz) to 3.8 with a 1v change, and still keeps it around stock temps. @ 3.5Ghz (what I run @ stable due to motherboard limitations) I hit a max of 40c core temp and an idle of anywhere between 16c-20c.
Stock temps were about 19-21c idle, and 38-40 under load.
Stock cooler was almost 20c more idle, and under load, so this is DEFINITELY a badass cooler.
It also comes with a fairly decent size tube of TX-4 Tuniq paste which is apparently one of the best in the game, so I went ahead, and used some of that on my HIS HD 6850, and I'll be damned, the paste alone dropped my temps enough to get a world record breaking overclock on stock air cooling. The heatsink also comes with a "RheoSmart" rheostat controller that also plugs into the four, or three pin cpu fan connector, to allow you to switch between manual, or motherboard controller speeds. (Which is pretty awesome IMHO) I absolutely LOVE this thing, and am 150% confident it'll be able ot cool my 8350 efficiently when I get it (if I don't end up waiting on the Steamroller cpu line.)
This is what you're looking for. According to several testers across the internet, this is right on par with a V6-V8 cooler...and over 30 bucks cheaper.

This is the validation for my CPU using the paste that comes in the box with the Twister 120 - btw, that's on the standard stock HS...nothing special at ALL.

990fxa-gd80v2 cpu voltage stability issues

I have had this board now for 2 mths and have noticed a problem with the cpu voltage. It fluctuates alot ie: set at a voltage it will fluctuate +/- .03-.06 volts. The most significant and generally highest fluctuation is at load where it will drop down usually .05 volts consistently. This greatly affects any adjustments one would make for OC as the maximum voltage for my AMD FX 8350 is 1.55v.
Point being: Is there anything in the works where MSI is addressing this issue. Is there a solution? or is this just a flaw we are meant to accept.
I just want to know that something is being done. I chose MSI for this motherboard because all my previous MoBo ran flawlessly.

It is not looking good. I hope I am wrong but I get the feeling from email response others have gotten that they may be moving on and these issues are a lost cause. Again I HOPE I AM WRONG.
On the plus side I have managed to get 4.6 easily stable and no real issues with the particular setups I use so Guess I can bide my time.

990FXA GD65 No boot

The issue:
About 2 weeks ago my rig started to hang (crash without a BSOD), monitor would go on to standby and audio
make that awful buzzing noise and then stop. The rig will just sit there, no reboot, nothing. I would have to turn off the psu switch off/on to restart the PC. Now this morning the PC won't boot.
The symptoms:
I can turn on the PC from the main button, all 8 CPU led phase indicators are on, all fans and water pump are on.
Nothing happens after this, no boot no uefi, no posting, no beeps.
The only way I can turn it off is via the psu switch.
Testing:
I tested the psu, all seems to be good, stripped the rig to just 1 ram, 1 v-card and CPU. No change.
Specs:
The rig is about 2 years old
Mobo MSI 990FXA GD65
CPU AMD Phenom II X6 Black Edition
RAM Kingston Hyper X Genesis 4GB x 4 = 16GB @ 1600Mhz
PSU Ultra X3 @ 850W
Video EVGA 450GTS X2 SLI
SSD OZC Vertex 3 @ 128GB
H2O Cooled CPU, VIDEO, SOUTH BRIDGE.
Any suggestions, fixes? I don't want to go and replacing parts as they are costly, I have mortgage and a family to feed. This rig I built with a lot of effort. Any help is well appreciated.

from that it sounds like you PSU is either failing or has degraded or it may be your Memory has failed! (buzzing noise is usually Voltage Ripple from the PSU and if its severe it may have killed alot of stuff: CPU, RAM, Graphics card, SSD)
try a CMOS clear >>Clear CMOS Guide<< and see if it works correctly as it may just be the RAM speed is overwhelming the IMC on the CPU (AMD IMC's are very crude compared to an equivalent one from Intel and are usually only able to run at a few step back (try 1333MHz))!

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

BIOS doesn't change CPU Voltage P55-GD65

I have a P55-GD65 with BIOS Ver 1.7
No matter what setting I put the the CPU voltage it seems to run in auto only. I have tried many combination's of settings that I have read on the forums but nothing seems to be working.
Has anybody had this problem?
Thanks,
Mark

Yes even when I have Intel C-STATE and Intel EIST disabled.
The voltage is much lower. I can't over clock because I cannot up the CPU voltage. I have the CPU multiplier at 21 and the clock at 155. If I go even up to 156 on the clock my system will blue screen.
When I put the voltage in Auto and monitor it and then put it in manual and crank it up to 1.45 and monitor it the voltage behaves as it is in auto. I have XMS 1600 memory and the Mugen B rev 2 cooler so I know that is not an issue. I might have a defective MB. I've been building PC's for years so I'm not a newbe. I've usually used Supermicro boards and this is my first MSI board. The board is very nice and if it worked it would be great. I was going to build another system with that board but am a little gun shy now.
Thanks for all your help.

I need a cmos reset after this settings.
if someone has the same problem, I would love to know.
I have already contacted msi

Overclocking problem with vcore auto?? it's a joke? this cpu works great with 1,280V on 4500Mhz why not work with vcore auto?
There is a considerable difference in Intel CPU's as to OC ability. It's called luck-of-the-draw. Jack is correct, your CPU appears it can't handle a 45X on Auto voltage. It's just the way it is sometimes. Another exemplar might even do 46X or 47X on default voltage. Is the 1.280v. confirmed by digital multimeter at the V-Checkpoint? 4.4 - 4.6 range is an average one might expect, but not an absolute guarantee on default voltage.

MSI 990FXA-GD80 B6 Max CPU voltage 1.27Volts????

So I have updated to the new B6 bios but unfortunately cannot set CPU voltage higher than 1.27 volts in bios to overclock -.-.

Having the same issue here, only I'm getting up to 1.365v listed... https://forum-en.msi.com/index.php?topic=153820.msg1136534;topicseen
Use version 11.5... It works good.
Also, on many games with Bulldozer, some motherboards will BSOD, or on the 990fxa-gd80 you get insanely low performance. Such titles include Shogun 2, Portal 2, Deus Ex: Human Revolution and many more. On the ASUS Sabertooth, a user was able to correct all of his problems by rolling back his BIOS to version 0705, but that doesn't really help us here much, other than to say hopefully MSI will also be able to correct these issues in a BIOS update soon...
As for me, I'm shopping for Intel/Nvidia parts now. I'm fed up with this crap. It's been one thing right after another with my AMD build....Never had any issues with any other system I've ever built in my life (been building systems since 386/486 days; over 15 years), but this one has just been a nightmere...Nothing against MSI - I love their products and hoping to get at least a couple gtx580 Lightning Xtremes, if not also one of their fine Z68 boards.

990FXA-GD65 & 970A-g45 Bios Question-HPC

I have 2 systems with pretty close to the same bios Feature. My question is a quick one, and I hope a simple one?
What is HPC-I know it stands for High Performance Computing-I know that it has to do with the throttling, under load.
What is the exact reason for this? Why was it added to the bios? Is this just for FX cpu's
Looking for a quick rundown.
When enabling in Bios-with everything on default-do you just enable? Do you need to turn anything off-C & Q? or do you just turn in on and go?

Should HPC be enable with the 2 computers along with all the STD setting in Bios
Thanks for your help guys

HPC locks the multiplier for the CPU at maximum setting so it has no LAG when asked to do a demanding job as its already running at maximum performance levels and doesn't have to wait for the CPU to realize that it needs to up the clocks from idle clocks(powersaving mode) to high performance clocks!
if you want no delay in performance thats what HPC is for as it will hold the CPU at its full clocks all the time...
as for C & Q that should be disabled as it may interfere with HPC mode and continue trying to throttle the CPU to lower clocks and voltages! if C&Q is off just enable HPC and it should function properly!

Problem with CPU Voltage

Hello
I build new PC with:
i5-760
Noctua NH-D14
MSI P55-GD65
G.Skill 2x2GB CL7 ECO
Antec TruePower New 750W TP-750
TwinTech GF 9600GT
I have problem with CPU voltage as even when I set it for example to 1.201v in bios, under load it overshot to 1.256-1268. The best is when I oc`ed cpu to 4GHZ and set voltage in bios for 1.30v it overshot for 1.45v+! Not to mention that temps are skyhigh from that. It doesn`t matter if I try to put BIOS Vcore on 1.1v on stock because under load it still rise to 1.16. I turned off all eist, c-state, turbo boost, phase led and switch phase, set vdrop to low and still something is wrong here. I updated the bios under dos from USB stick to newest 1.9 version in order to update CPU micro code without error and it not helped. I want to know is that even possible to fix or should I RMA MB or CPU.
Minor problem is with sysfans as they power on for a second and turn off instantly to start working again when I see list on devices in post. After rebot when my monitor is switched off it takes something like 5 sec to power monitor on and another 5 to show bios, is that normal?

I have similar issues, it's hard to tell which measurement is the most accurate, there are 2 different measurements in the control center that don't match up with the figures set in the bios. The only way to be sure would be to get an expensive accurate multimeter but If you're only interested in running a stable overclocked computer without knowing the exact figures then get the computer running stable and lower the voltages until it starts to become unstable with prime95,
Or you could work the other way round, set the voltages so it boots but doesn't run prime95 for long, then raise the vcore and vtt one at a time until your happy with the length of time prime95 runs without errors. I'd be happy with 24 hours, I seem to remember errors creeping in at around the 9 hour mark on the setting below what I have it set to now.

MSI 990FXA-GD65 + AMD FX-6300 + 16GB 1866MHz RAM Won't Boot

Hello,
Today I received parts for my new gaming system (sans water cooler, using the stock heatsink+fan until then), however I'm experiencing problems with the setup. The specs are as follows:
- MSI 990FXA-GD65
- AMD FX-6300 CPU
- GSKILL 16GB (2x8GB) 1866MHz DDR3 RAM
- Kingston SSDNow V300 120GB SSD
- 2x MSI GeForce GTX 660 Ti
- EVGA NEX750B1 PSU
- BitFenix Comrade case
Upon powering on (after assembly), the Phase Indicator only has the first two LEDs lit up (Phase 2 Power Mode, according to the manual). No output is displayed on screen. I've tried removing and re-inserting the CPU and removing one of the graphics cards, to no avail.
I would appreciate any help/advise that could be offered, that I might get this system up and running!
Kind Regards

Try to run this system out of the case on non conductive area (e.g. plain cardboard) with 1 stick of RAM only, 1 GPU (try without any graphics cards too), single HDD/SSD, PSU of course, CPU+cooler and monitor+keyboard and mouse. When booting spam Delete and it should take you to the BIOS where you have to change timings of RAM suggested in the post about GSkill memory.
If possible, borrow different brand of RAM to test your PC with.
Make sure that if you're running single GPU, that video cable is connected to the card. If no GPU, then to the motherboard.

990FXA-GD65 MAINBOARD POWER CONNECTORS

hi,
I am building a new system using your 990FXA-GD65 board and an AMD 8320 chip.
I am at the part where I must connect power connectors. I see that there are 3 connectors: JPWR1, JPWR2 and PWRCONN1.
My Power Supply has the 24-pin cable for JPWR1 OK. But it does not have the 8-pin cable for the 8-pin JPWR2. It only has 2 x 6-pin connectors labelled PCI E1 and PCI E2 and another 2 x 4-pin connectors labelled CPU1 and CPU2.
The power supply I have is a OCZ 700W unit (OCZGXS700) and its about 4 years old.
What to do? Can I just leave the connector JPWR2 unplugged? Or will I have to purchase another Power Supply?

connect both 4pin CPU ones to JPWR2 as that is a 4+4 connection and if you look at the pins its 2 identical pin sets as a 4 pin so use both.

Limited vcore 990FXA-GD65

I have a 990FXA-GD65 and from what I can tell there is a revision 1.0, 2.0, and 3.0. What is the best, most accurate way of finding out the revision of the board? Also, do any of the beta bioses allow more voltage adjustment? The vcore can only be set to 1.45v in the bios, it can go higher in AMD Overdrive. I'd like to not use overdrive anymore but the board doesnt allow enough Vcore adjustment for me to do so.

Its been a BIOS restriction for a long time, and it was introduced when the FX8000 series were launched.
These CPUs start spiking to over 200Watt TDP when overclcoking. The board was designed before these CPUs were launched and thus the VRMs are not safe at those power requirement levels. To protect the VRMs from burning up, the restriction was added.

990fxa-gd65

hi i have a msi 990fxa-gd65 whit fx4130 cpu and i wonder why the cpu temp is inkorekt in bios ? can somone tell mi why ?

When you are in your bios at startup, not ClickBiosII, the temp is likely correct but:
Your CPU will be running at max clocks and not running any powersaving feature like Cool and Quiet. Therefore the temp will be somewhat higher. On mine it wil run anywhere from 38C to 48C depending on if it was running prior or not. After windows login, where the power stages are run like C&Q, It will operate like normal and for mne those temps are as low 27C and only ever really get to 45C under some moderate load. All these tamps are socket temps. It is no big deal.

MSI Military Class II 990FXA-GD65 - No Signal

Hello. I'm an amateur builder and this is my third project. I've spent many hours trying to figure this one out with no luck, so here I am.
All the components are new, save for a stick of RAM. Everything seems to have power. I've only had it boot into BIOS once. As soon as I moved the mouse I lost signal to the monitor. I have not been able to reproduce this. I have cleared CMOS, reseated everything, tried a different monitor and video card and took it down to one weak stick of ram and one HDD. I've also tried using a VGA cable to no avail.The only thing I haven't tried is powering up the Motherboard outside the case. I haven't tried it because I'm under the impression that the motherboard had to be grounded to the case to work properly and safely, but I have seen it suggested on this forum in other similar threads.
Any words of wisdom would be greatly appreciated.
