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 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.

GTX 660 TI with 990fxa-gd80v2 3 way sli issue

Just added a third video card and 1200w PSU to my rig. The card shows up as "windows generic display adapter" (or some verbage similar to that. I wiped the Nvidia drivers and re-installed the latest release. The card still doesn't work (says it needs driver update, when you try to update - it says it is up to date.) When the PC reboots after the driver update, it shuts off video display after the Windows 8 splash screen. I have to power off and restart. After the third restart, it goes into windows repair mode. It tries to roll back to a previous version and then cannot complete the task. I continue to Windows and it goes all the way through. The card still doesn't show and SLI settings are reverted to defaults and not saved. Are there BIOS settings for 3 way SLI that need to be changed? It worked fine with 2 way. Do I need to update a driver for the PCI controller? Clear CMOS? Any help or ideas appreciated. Hoping to not have to do a re-install of Windows 8.

New build from Win 7 to Win 8. It was fine with 2 way and my old PSU. When I would 3Dmark the rig, it would restart after the combined test - So I figured the PSU was getting sketchy (everything but the PSU and case was new at this point.) So, in other words - Win 8 with 2-way with old PSU was ok. Win 8 with 3-way and new PSU is not working yet.

New rig 990fxa-gd80v2 wont post debug code 19

I am building a new rig for my gf's brother and i can not get my new mobo to post. I am getting debug code 19. I couldn't find a lot of info on what the code means but from what I have seen its apparently a problem with the BIOS not being updated for my new CPU. I have tried all of my current working components from my rig on the board as well and it still showed code 19. Here are the specs on the rig.
MOBO 990fxa-gd80v2
CPU AMD FX-8320
PSU 500W RAIDMAX
GPU EVGA GeForce GTX 560 Ti (Fermi) 1GB
RAM G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600
Like I said however I took apart my rig completely and switch all my known working parts onto the new MOBO and got the same error code. So I am not sure if the issue is really an outdated BIOS because it wouldnt post with my AMD Phenom II X6 1100T Black Edition. Any help would be greatly appreciated.

ok so it has been a few days since I last posted because I have been busy but I just finally had time to work on it. I essentially took out my mobo and replaced it with the new one that had been posting code 19. Using all my known working components from my computer including my PCU I am still recieving the same error code, even after moving my known working RAM into each different slot.I'm getting quite desperate here now and just am plain lost in trying to understand what seems to be the issue. I'd be very grateful for anyadditional information/tips here. Thanks.

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-gd80v2 having usb 2.0 issue

The problem is only with the 4 USB 2.0 slots that are on the I/O of the board. The USB 2.0 slots on my case (that I hooked up when installed) work fine and the USB 3.0 ports and the esata/USB 2.0 combo ports work fine. Windows will "unrecognize" and the quickly "recognize" these USB ports. It makes that 'sound' like you are unplugging something from the USB port and then plugging it back in again quickly. This will happen one time or several times untill the ports finally "die" completely and then later they become recognized again (maybe once, maybe several times)! I have moved all my connections to other slots but the problem still interferes because as the problem is recognized and unrecognized it pauses my mouse and keyboard when in use. Same thing with printer. When the problem happens it will cancel the action mid-print! I've already looked into it being a driver compatibility issue but the problem is restricted to the motherboard's 2.0 ports and nothing else. The board has a "de-bug" code thingy built in and the only code i get from it is 99. Since I have not been able to find any code lists for this MB anywhere, I have no clue what this means. To me (tech-level medium) this is clearly a manufacturer defect.
At this point I'm going to attempt RMA. I don't know what else to do unless someone, anyone can suggest a better solution. Any help is appreciated. This really makes my opinion of MSI become something undesirable. This just might be the last and only MSI product I ever buy!

I remember the part about "bashing" in the rules and I apologize for it. In my opinion it was a "mild expression of my first impression". But it's not my opinion that defines "bashing" in this forum. For that I am truly sorry.
Thank you for the suggestion about the non-conductive surface. It's worth a try anyway.If this could be the problem then what could be the problem causing it or the solution to it? Bad grounding of the I/O plate on my case or bad grounding of the case itself?

Anything I should know about the 990FXA-GD80V2 before purchase?

I'm considering getting a new motherboard in the next few days or so, and currently have my eye on the 990FXA-GD80V2. I plan to pair it with the FX-8350 and a R7850, and likely use Linux.
I was wondering if there was anything in-particular I should know before buying this board. For example, I recall reading somewhere that someone had to do a BIOS update to get their FX-8350 to use the right voltage or something.
I'm doing a good bit of research myself, but I'd like to avoid another experience like the one I had with ASRock.

Quote from: miklkit on 28-August-14, 22:46:41
I read your post about Asrock. Not good, but no 970 board is up for the 8350. Only experts with mega cash to spend on exotic cooling can keep that combination alive.
The MSI GD80 is a solid cool running board that can handle any FX cpu. My 8350 will bench and run at over 5ghz with air cooling but is stable at 4.7 ghz for everyday use. The 9590 is good for 5ghz for every day use. Because the GD80 runs so cool air cooling can be used making this a very cost effective combination. I am currently using an ASUS Sabertooth board and it runs hot. Water cooling is required to overclock it and I will be going back to the GD80 soon.
MSI is very conservative with their bios settings, which means that you can only run stock clocks unless the utilities provided on their cd are used. But last December they castrated those utilities too! I prefer to use ClickBiosII, and here is a link to a working version.
https://www.dropbox.com/sh/gpalg0tpyyfcivy/AAA_vvHgq7MUkdcXPH3Nh5rWa/CLICKBIOSII.7z?dl=0
Thanks for the feedback. I'm curious though, what exactly about the ASUS Sabertooth board makes it run hotter than the GD80? Would figure the CPU temps to be relatively the same, but maybe you're talking about another component like the VRMs or NB?
Also, what's that ClickBiosII thing? Is it a custom BIOS? From quick-glance at the archive, perhaps it's a BIOS-configuration tool that can be used from Windows to directly-alter the BIOS?
I put in the order for the GD80V2 a little bit ago; seems it'll be a manufacturer-refurbished board. Does anyone happen to have any first-hand experience as to how warranty is handled with such hardware? From my understanding, it seems used hardware carries whatever warranty existed since the hardware's purchase date, but refurbished hardware carriers only a 90-day warranty. Is the 90-day limit true, and if so, is it a "hard" limit (as in, you get absolutely 0 support after 90 days), or perhaps handled on case-by-case (MSI "might" be kind enough to do the RMA after 90 days depending on issue)?

What may it be? RMA only option?
TIA for any help.

Ok, here are the voltage readings from BIOS
VCore 1.456-72

-12V 11.825V
-5V 4.926V
Battery 3.088V
+5SB 4.896V
(The numbers after the hyphen '-', indicate a switching value)
The multimeter reading at a molex (yellow cable) says approx +11.79V at Win XP desktop idle and 11.68V under the game. Red cable on molex shows 5.12V while idle, no drastic change under load.
Just curious, how are the general opinions about electrical
readings. should they never go below the voltage they must
feed? Or is there room for some margin the voltage can go
below?
Havent yet tested changing videocard, will do that. Having no temperature sensors, cant check easily vga card temp.
btw, 'Apic Acpi SCI IRQ' isnt enabled in bios, is this essential?

N580GTX Twin Frozr II/OC Stability Issues

Hello! I've recently purchased an MSI N580GTX Twin Frozr II/OC and I'm having the much talked about stability issues (CTD, black screens etc.). From what I've read it seems like the best solution is to tweak the voltage in Afterburner until you find a stable solution and then after thorough testing, request a custom BIOS flash.
Is this the best way to go? I'm presently at work so I can't actually get started right away but I'd like to have a game plan in hand for when I get home tonight. Currently my card clock settings should be what they were out of the box although I've also read that some cards didn't come over clocked so what it says on the box might not be exactly what it's running at. I can look up the various card details this evening if it's necessary.
Also I'm not super concerned if I had to down clock or if the card didn't come over clocked. I just want to get it running stably

990FXA-GD80 - Incorrect voltages

Hello All,
I just picked up a new MSI 990FXA-GD80 V2 am experiencing some interesting issues. My CPU is a 960T that unlocks to a stable hex-core. On default settings, everything works as it should. When I set a voltage manually in the BIOS, things start to get wonky. Cool 'n Quiet only has two voltage states: one is .04v - .06v over the voltage I set in the BIOS, and the second (which only comes into play at high load) is .04v - .06v over the first. For example, I have the CPU Voltage in the bios set at ~ 1.31v. The voltage for idle through ~ 80+% utilization is 1.35v - 1.37. The voltage at max load is 1.40v - 1.42v.
The board came with BIOS version 13.5. I reflashed the BIOS to see if that might have something to do with it. I even flashed back to a D4 BIOS and the results are the same.
Is this typical behavior with the D4/D5 BIOS and a AM3 CPU? If anyone could shed any light on this, I would greatly appreciate it. I will be finishing up my troubleshooting, and isolation of the problem when I get home from work tonight, then I will be contacting MSI as well. I will be sure to post any reply I receive from them here.
The system specs are as listed in my sig.
Thanks for your time.
P.S.: I prefer to overclock with Cool 'n Quiet on because the CPU is cooler and far more efficiently utilized with the lower power states. It is, at max, a 1% penalty on a Phenom II. The increase in the longevity of my CPU worth the extra 30 - 40 Mhz to me.

Quote from: Fredrik on 11-August-11, 07:37:52
Odd you get correct(?) readings from software programs - they have no separate thermometer. Sure, BIOS may be incorrect. That is a common problem, but then your monitoring programs should be up the wall, too. More common is in fact, the BIOS readings are correct and programs are wrong.
Comparing with a different system is impossible. Case and cooling can not be the same; a case built for a Pentium II wont cope nicely with a 6-core processor of today.
well apparently its happening to me, and im not the only one. That other dude using water cooling and his bios temps are 20C of true readings. looking at it from a coding perspective maybe its just adding 20 to the temp. by mistake, but i can't say for sure since I am expert in programming languages not so much into BIOS and firmware kinda stuff.

990FXA-GD80V2 and water cooling

Hi,
Been combing the web trying to find an answer for my question and stumbled upon this forum. I figured you might know. I just purchased a combo pack on Newegg that had a MSI 990FXA-GD80V2 motherboard and AMD FX-8150. Seeing how the stock fan/heatsink barely keeps the heat in check i was looking for alternatives. What i want to know is if the motherboard would work well with the CPU cooled by lets say CORSAIR H80 water cooler. I know from recently help a friend with his rig that without the normal CPU fan some motherboards them selves overheat. Only way we fixed his was to bolt a separate fan on the mobo for that issue.
So a recap on my question. Does the motherboard its self have adequate cooling to allow the CPU to have watercooling?
Thanks

The question of heat is covered in a few areas.. air flow of the case itself.. to include amount of fans, and if you plan to run, in your case the FX-8150 overclocked or not. At stock speeds the CPU cooler that came with the CPU will work fine.. possible with even a small OC. If you are planning to OC and/or play with variable OC's and testing.. a better CPU cooler is the way to go. The new water cooling systems like the H80/100 and other self contained water coolers are good. Better than a self built water cooling system, there is less chance of leakage.
If you take the time to look at CPU cooler reviews... a lot of good air coolers are cooling better than a cooling system like the H80. A real nice thing about the coolers like the H80 is airflow in the case. It also takes a case that can handle the size of some of the air coolers. A lot of them are huge in size. I have a friend who has both the H80 and H100. He tells me that he likes the cooling of the H100 better. He does serious Overclocking. I also own the 990FXA-GD80 and have an FX-8150 on the way. I am using a Zalman 9900. I plan to continue using it.. that said, my friend is trying to talk me into an H100. My case is the Antec 280 and it is possibly the largest case on the markey with 7 120mm fans running, plus the CPU cooler. If you look at the bottom of posts we list our equipment. Being new here, you might not have read the posting guide. If you give us your information, how you plan to use and overclock or not we can give a better answer.
To focus on your question.. like Svet answered... yes, the H80 should do a good job.
Good Luck

990FXA-GD80V2 Very slow internet.

My symptoms at their best involve small bursts of internet in between total inability to send or receive any data. This has been going on for about a month now, getting progressively worse. Most of the time I get very little bandwidth, barely enough to navigate to this forum. If it tells you anything, I had to wait for the smiley face emotes to load in the start new topic page. This isn't a problem on my ISP's end, every other computer in the house is getting along just fine.
When I first completed this build everything was lightning fast. It appears to be deteriorating over time, and I can't for the life of me pin it down to any particular software issue. I've done thorough sweeps for spyware and viruses (preboot, postboot, with multiple programs) and found nothing that should be clogging up my system.
I had one ray of hope when I tried disabling NetworkGenie. For a few hours I had no noticeable losses in my bandwidth, though still much slower than it should be. I was playing FarCry 3 for a while and tried to normally use the internet when I noticed it was slow/nonexistent once again.
It may also be important to note that I never see my system tray say I am disconnected from the internet. When I seem to be completely disconnected I have watched the send/receive packets to see that very very few will occasionally send, and none receive, until I get a spurt of bandwidth again if I am lucky.
Any help would be greatly appreciated, thank you.

Well could be a few things.
I am betting on software, the virus program itself or just something didn't install properly.
Here are some ideas:
1.) Eliminate software - re-install the os (or refresh it if it is win 8)
2.) Remove the mainboard from the case and place it on wood or plain cardboard (non conductive surface) and re-build it there and test.
This will eliminate any shorts.
3.) While this problem seems limited to Intel NIC's, check the mac address and make sure it matches the sticker on the nic.
4.) Update the mainboard bios: http://us.msi.com/product/mb/990FXA-GD80V2.html#/?div=BIOS

The mic is in the mic, and ive got a lead in mic in and one in mic out.
I downloaded the new drivers and the sound is gr8!

I still have problems loading windows and am getting repeated CONFIGMG windows protection error. I'm not too fussed about that because once its up and running, it runs like a dream.
Q.Any ideas as to why my 3dfx is so comparitively slow? (Yes I know I should go out and get a Radeon 9700 pro gti turbo ultra gold.........)
A. That'll be the z-buffer disabled...
I found some more info that might relate to my configmg problems here:
http://www.easttexaschat.com/_tips/VxD_drivers.htm
But sadly it didn't work for me...
Its interesting that ECS got SLATED over this configmg error and some bright spark soldered a resistor onto his board which seemed to work. It was put down to a SiS chipset needing to be at a certain temperature - i used this fix and it worked.
Could it be that a conventional system fan could be placed hear the nvidea heatsink to solve this problem? As configmg errors can be motherboard related, could this explain poor memory compliance? Could this explain its refusal to home my little geforce2 gts...?
And the answer is YES. The chipset cooler is inadequate. 8o
**The configmg errors have stopped.**
I used a standard 80mm case fan and modified it using a 2l plastic coke bottle so as to channel the air onto the heatsink without damaging it. Previously it was difficult to get windows to load. Now it has succsesfully loaded 10 times.
**I am now using the default memory timings without a problem - thats 6,3,3 Cas2.5**
Bear in mind that I tried these timings with my matroxg450 previously, and it resulted in crashes.
Now for the final test... I shall trawl out my geforce2 GTS - source of all my initial troubles with this board - could it be that the performance of this board was straining the chipset when it wasn't properly cooled, or is it still a device driver issue?
Well, during instillation of the drivers I got 2 VxD BSODS. I tried 20.xx 30.xx and 40.xx which all failed to produce an image using directx 8.1. Guess this board just doesn't like the card.

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.

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.
Mark
