MSI 990XA-GD55 power phase design

Hi, I am new to the forum. Bilding my 1st rig and am just wondering what is the power design of the 990XA-GD55 MB is it 8+2 or something else? Can't find info on that anyware... MSI shoud have that info at the MB's home page, it's very helpfull in diciding a MB for the rig. I like this MB a lot. )) Thanke you, bye.

MSI 990XA-GD55 Mobo: Boots fine, no POST/chance to enter setup

So I have built my own setup here, been running it since May of this last year. I never thought about it until recently, but my computer has never done a POST, or shown me the screen that allows me to get to BIOS or Boot screens. The computer has been running fine, until recently (About a month ago or so) I will be playing any kind of game, and the computer just COMPLETELY crashes. No closing of the game and shutting itself down, no blue screens, just one second the comp is running, and the next it is shut down. So I did a stress test of CPU and GPU to see if they were just overheating or were on their way out the door... But both passed stress tests just fine. I then wanted to check my memory/BIOS, and this is where the no POST and setup screen "clicked" for me... I have been searching everywhere for info on this topic, and the best I can come up with is that there is a problem with my G Skill memory not being recognized? I have DDR3 1600 going, as it shows I can use up to at least 1866 without OC on this mobo. So I went to check what my BIOS said, went to owners manual to see how to get to it (As I never saw the screen where it asks you to press "Delete" or F11), yet in the manual, it says to look for exactly that. So I guess my MAIN question is... How do I get my computer to show me that screen on startup? I have read to reset the jumper to the 2-3 position for 15 seconds on the JBAT, and if that does not work, to pop out the CMOS battery... But wanted to get other opinions before I attempted such things. And in doing this, and possibly getting to the BIOS screen, will that even help me with my original problem of my computer all of a sudden crashing in prolonged "stress" situations? Ie, playing Lord of The Rings Online, I generally have to play for a few hours before it crashes as such. I tried to play Assassins Creed 3 today, and it crashed in the first 10 minutes. This led to my investigation into the GPU (As it only really occurs when playing video games). I was thinking the system was just overheating and auto turning itself off to protect, but after doing the stress tests, GPU stayed pretty stable at 80-85c over an hour, and CPU stayed below 76c on an hour stress test. I even did an hour PSU test, no crash... The only thing I can think would be memory.
I apologize for the multitude of questions and possibly incoherent order in which I wrote, but just trying to get as much pertinent info/process I went through as possible. Thanks in advance for any replies, and will be happy to give any extra info if needed!

EDIT: After looking through all the left over cases from items I purchased when building this comp, I realize I actually purchased 1866 DDR3, not 1600. But in looking at system properties here, it registers as 1600... But as I said before, I cannot access BIOS to adjust these values. Or maybe that is my problem in first place?

I was wondering about a good voltage for this setup, I think these two are running at 1.6V to start with... So going lower voltage would be ideal then, hmm? Less heat, less power consumption, and you do not have to worry about a decrease in performance? Especially if the latencies are lower, correct?
And I hate to say this, but I have had one of my first "noob" moments ever with this problem... It has been a few months since I took some compressed air to the mobo.. So went and bought some, blasted the heck outta the CPU/GPU/PSU, and the North/South bridges... Ran the same CPU stress test for twice as long, and it hovered at 41c, 42c was my max... *facepalm*. Before, it was even overclocking the CPU to 3.8GHz or so to work with the "data" it was running.. After compressed air, never really went above the 3.6 stock speed. I have never felt like such a goober!
As for the BIOS, turns out the F lock solved the problem, as the delete key is somehow considered a function key for this keyboard I guess. Was able to get into the BIOS, do some tweaking and all. Still nice to know that these newer systems dont beep anymore, and where to start pressing the delete key, instead of mashing it from boot!
Yet again, thanks for the tips, and this bit on memory/RAM is interesting, thank you for that input as well! I do not plan on upgrading the CPU any time soon, unless it is in a weakened state thanks to my neglect.. But I am still fuzzy on RAM details, so the mention of Latency/Voltage helped me in my upgrade search, thank you! If I am understanding it correctly, the 1866 will be future proofed, as well as having the ability for lower latencies compared to 1600? Does my system not go to 1866 because of the CPU or the mobo? As I thought the mobo supported up to 2133 OC.. So most likely the CPU, correct? I am looking at some Mushkin memory, if I get some 1866, I can lower its frequency to 1600, but decrease its latency in the process? ie getting some CL9, and lowering it to 1600 and CL8? How would I go about this, if you do not mind my asking? (If I understand correctly).
Thanks again!
EDIT: I brought up the msi control center, and see that my RAM is actually running at ~1.5V. How can I see the latencies it is running at? It is rated at CL9 at 1866..

Msi GTX 770 lightning compatability with an msi 990xa-gd55

Soon I will be upgrading my pcand cant be sure from my research that the msi GTX 770 lightning is compatible with the msi 990xa-gd55 motherboard. So I thought I'd ask for a proffesional opinion. Thanks

You're welcome!

MSI 990XA-GD55 + Vertex 3 Max IOPS SSD

I used to run my V3 MIOPS as the boot drive on an AMD 890GX+SB850 chipset motherboard with an AMD Phenom II x4 840 cpu. Everything was perfect and the computer was snappy. Programs opened instantly and multitasking was effortless.
Then I upgraded the motherboard to a MSI 990XA-GD55 (AMD 990X+SB950 chipset) and replaced the 840 with the 1090T. I secure erased the V3, cleared CMOS and did a fresh install of Windows 7. Immediately I experienced freezings. I was advised by a member on the OCZ Forums to change the AMD AHCI drivers to the generic MSAHCI drivers. This stopped the freezings and improved the 4K Read/Write performance tremendously.
I don't get freezings anymore and the computer is 100% stable. But whenever I try to open a new program or multitask I experience a lot of hesitations, not freezings. It's like the system is waiting for a routine to complete before passing back control to the user. This makes my computer less than snappy. The hestitation is usually a very short instance when I open a program but could be a few seconds if I already have a lot of apps opened and I'm opening a new app.
AMD does not have specific SB/AHCI drivers for the 9xx series chipsets. I'm wondering what I can do to return the computer back to the snappy performance I used to enjoy with my old system. I suspect that AMD's new 990X chipset is the culprit. Does MSI have any new (beta) BIOS/drivers I could try to bring back my computer to its past snappy performance?
Thank you in advance for any response.

Just want to give an update here.
I've fixed the problem by combining the suggestions given by MSI Technical Support and the ppl who responded to this thread. Thank you.
MSI Technical had given me a new BIOS to try but it didn't fix the problem straight away. I suspected it was because of the AMD drivers I had previously downloaded from AMD's site and already had installed. It seemed that the original AMD drivers did not work well with the 990XA-GD55 plus the Vertex 3.
This is how I made it work. I left the motherboard BIOS at the newest version, ie. V22.2B6. I secure erased the V3 and unplugged it from the motherboard. Then I thoroughly cleared CMOS and took out the battery for 15 minutes.
Put back everything together and loaded the optimal defaults in BIOS. Set SATA to AHCI and rebooted with the Win 7 installation disk. Performed a fresh install of Win 7 (as recommended by Bas) but only used the drivers in the MSI Install Disk that came with the motherboard.
Now everything is faster, especially the 4K performance of the SSD. I don't know about the "hesitations" as I haven't used the computer long enough yet (just finished re-installing all my apps). But the computer is now just as snappy as before. And yes, I'm now on AMD_SATA and not on MSAHCI.
My conclusion is that the drivers (Catalyst/SB/AHCI) available from the AMD site is not good for the motherboard but those provided by MSI are perfect (in my case at least).
Thanks again to everyone for their help.

MSI 990XA-GD55 and Corsair Vengeance 1866mhz problem!

I got MSI 990XA-GD55 and 2x4GB Corsair Vengeance 1866mhz but i tried everything to get it run at 1866mhz and i couldn't. It doesn't even run at 1600mhz. Only at 1333 or around 1500mhz. I set the timings manually but i doesn't work. Am i doing something wrong? Anyone can help me to figure out?

Quote from: dyeladreash on 30-May-12, 19:27:53
By saying memory controller, it's about CPU or mainboard?
AMD cpu's from the phenom series support 1066/1266/1333/1600(usually only supports that with an overclock and 2 dimms installed) MHZ on the memory controler! only way you can get more frequancy is by overclocking the memory controler on the cpu to allow the increased frequancy on the dimms (most ram that says its 1866mhz is ment that its been tested overclocked at that speed but the chips will more then likely be 1600MHZ)!

Hi,
Just trying to do a build, got the computer running with a old graphics card but when I put in the Radeon 7870 card no signal is sent, the card fan spins so guess its fully powered, just took battery out to refresh CMOS so will try again after a hour, have read some comments on flashing the BIOS can sometimes cure it, the board version is MS7640 v4.0 , so guess thats the 7640vM4.zip update?

Please don't tell me card is duff..... :/

CPU Core Temps Gone With Genie - AMD 1090T + MSI 990XA-GD55

When I turn on Genie the core temperatures of the CPU only shows 0 degrees. Is this normal?

Thanks Hu. Please excuse me if I seem to be a noob. The fact is: I am!
Anyway I disabled Genie and manually set the CPU multiplier to x18. This is what I got.
The core temps are back. Don't know what to make of this.
Is Antec a bad PSU? I might have to consider ugrading that then.

MSI 990XA-GD55 Low FSB and CPU voltage cap

I just purchased a brand spanking new 8120 and I'm loving it right now. I've been steadily OC'ing it and have gotten it to 4.5 Only with the multiplier. I wanted to do it with my FSB but it will only go up to 225, after that it stops posting. I keep everything close to stock as i pump it up but if i go up to 226 and keep everything low it doesnt post. I thought that was fine and didnt worry about it till i saw people hitting 250+ with their MB. is it my board thats bad or am i doing something. I also cant up my voltage on my cpu past 1.4v which puts me at the 4.5 with a core temp of 50 running prime95.

>>Posting Guide<<
Do you know you can't just up the Reference clockrate ("FSB") without modifying the HT-Link to not massively overclock the linked components.
Tom's Hardware made a basic How To for K8 which will even for FX still give an idea: http://www.tomshardware.com/reviews/phenom-overclock-athlon,2161.htm

I have a 990XA-GD55 With One Click Bios II-Am I alone?uefi?

I created a post not to long ago asking for help with a situation. I bought a new Board 1 week ago. Board was Brand new, never opened...
"""This Board Is Not suppose to Have A Uefi Bios.....This Board is Not suppose to have One Click Bios II........"""""""""
The only reason I bought the board---The company I went to purchase, Had a deal on another board with a Pile-driver Processor. I am the type that will read and read, till I know everything about an item before I purchase..Found out that most of the time, you can purchase a combo and find out that the bios has not been updated for the cpu. Only way to fix, buy an older or cheaper cpu and update. I talked to the salesman and come to find out ,the combos they were offering had the same issue..This board had the uefi Bios...I did not want to go threw the head ache, so I opted for a different board..I was told it had no uefi Bios...and I was fine with that, It was a better Board. But than I found out that it too, was not ready for the pile driver...But it was ready for the bulldozer. I have owned the same cpu before. So I purchase The bulldozer and this board-990xa-GD55....
Brought it home-read up on it.....Read it did not have uefi bios...and that was fine...Built the unit top to btm.....Booted it up or hit the power button.....For some reason it took about 30-60 sec to come on. But once it did...I hit delete too get to bios..Guess what I seen--One Click Bios 2..That was weird but ok...download windows 7 all my drivers, all my updates...But I could not find the download for one click bios on the site or on the cd....and everywhere I read claimed that this board was not to have this bios. I even wrote a post here asking about the download...What I was told---This board does not have uefi Bios....So I responded with a pic of my bios and I have not heard back..
I would like to hear from users just like me on this subject..Do you have the same Bios I have? It says One Click Bios II...I am not complaining...This board runs awesome and does everything I need it to do. I am very pleased. I wish I could get the download to have one click on my desktop..Like my other-boards...I am not a newbie to building, and I have had this bios on a few different computers. I would just like to hear, if you might have the same bios...and any issues you had when updating...I am scared to update the bios..I probably will not do it..I would hate to lose this feature.
Thanks for reading and sorry about my Grammar and spelling....
Update--I have been beating my head over this...I know MSI says we are not suppose to have this bios....But if you look up this in Google..
Can't change CPU voltage on MSI 990xa-GD55 Mobo
Look at the screenshot....That guy is using one Click Bios 2----tooo........
I have a feeling that alot of people that buy these boards are new to this bios feature, and just don't know better...This is suppose to have the older version of Bios....Not one Click 2...Guy in this post as the same bios as me.....Maybe if enough of use tell these guys we have it--They will include a download for it on Windows...On my other boards...I have one click bios on the board and can access it in Windows with a simple download....Thanks MSI for this feature...But please hook us up with the download too.......I would use the download from another board-But I know better...so I can wait till MSI offers....

If you are reading this and you are like me. You came here for answers. From what the guys here are telling me and from what I have read. These boards are not advertised as having the bios. When I purchased this board I was told that this did not have it. Than in my other post I was told this did not have it. But after a long winded Post. The Msi Tech said these boards come with it and that this model does not support the One Click Bios 2, in windows, Like there other boards. To me that really makes no scene, But I don't make the boards. I am sure these guys can write a program to take advantage of this awesome feature. I did some more hunting and amd has nothing to do with it, so i am assuming it is just this chip-set. To me this really make no scene. But having this bios was Bonus. If you read online or any review-either the person writing the review really never used the board, or maybe he never tried the bios. But I found numerous reviews claiming this board was missing this uefi and it only came with traditional Bios. 'Makes You wonder".........But I am over it....If your wondering these board do come with the uefi Bios but not advertised..advertised as having the older traditional Bios. Hope they will come out with an update for the one click Bios feature in Windows soon.....works out nice when you need to dbl check setting with out resetting your computer..
As for Ram--I asked about using 2133....One the many Msi Boards I have used in the past. There boards have a feature That allows you to just tick what frequency you want to use and than it will set the timing for you. I understand that Your memory controller is in the chip...But this program is in the bios. On This board the Highest is 1866...But when pressing 1866, it will not run it stable. sometimes it wont even post. The ram I am using is g.skill 2133 and i have used it in tons of there other boards with no issues. I have even used it in another bulldozer set up at 2133, Different board....Ran well. This board Can use 2133 easy, but in order to do it you have to go in and set the timing and voltage...Not a big deal for those people that do it all the time. But I like the one click and go. Even though one of the ticks is 1866, this board will need adjustment...so anything over 1600 will need to be done manually. My original question was this board says it can take 2133oc...I am one of the few that know nothing about setting timing and voltage, But with this board I am learning...if any of you have this board and this ram.....f3-17000cl11-4gbxl........Let me know what you set yours on to run at 2133....I have already tried----
11-11-11-31-41"1t and 2t" voltage 1.6.......and it does not run stable.....Maybe I just lucked on on my other board, but I do not own it no more to compare...I would like to hear how you got yours to run stable.......I don't need it.....I just want to do it...
Thanks for reading and sorry about my spelling and grammar.....

990XA-GD55 990X Chipset Heatsink EXTREMELY hot.

My PC has started giving BSOD's, and when touching the heatsinks to see if anything is overheating, the 990X heatsink (the one Below the CPU) feels EXTREMELY hot, warm enough to burn a finger if held there for over a second. (65/70C ++ )
CPU is at 45C, Mainboard itself at 32C, Graphics card at 36C (Whilst playing games)
I wish I had a IR thermometer I could read the temperature with.
Is it normal for them to go super duper hot? Could this be as a result of a BIOS setting regarding C1E or Phase control?
The side of the case is open, and the PSU is sucking hot air out of the case causing circulation.
Nothing is overclocked.
AMD FX-4100
MSI 990XA-GD55
MSI 460GTX Cyclone
Corsair Vengeance 1866mhz DDR3 (2x4GB)
Corsair Force3 SSD
Corsair TX650 PSU
Creative X-Fi Platinum PCI-E
Seagate 7200RPM SATA II (2X1TB)

I like my computer to be silent, which it is.
All the other components are fine.
If there really is an issue with inadequate airflow (which I find hard to believe) why didn't MSI fit a fan ontop of the heatsink themselves?
CPU cooler is the OEM one from AMD.
No Intake fans, No exhaust fan. (System temperature is fine)
The PSU sucks up all the warm air from the system and spits it out, which draws in fresh air into the case.
I know this setup (With this fan arrangement) is fine, I have ran it for many years without any issues.
Only part that seems to give an issue now is the 990X chipset heatsink. And only during heavy gaming for a prolonged time.
On idle I estimate it to be around 50-55C
Idle system temp is 29C. With the CPU at 40C.
The four cores (According to CPUID Hardware monitor) are at around 15C each.
SSD disk is sitting at 30C.
GPU at 33C.
Can anyone else with this board see if theirs is the same? I rather suspect that MSI made a mistake by not fitting a cooler on it from stock.
Its also in a rather bizarre location, sandwiched right between the CPU and GFX card, with the RAM on one side and the huge heatsink to the left of the CPU on the other side.

After overclock my 990XA-GD55 motherboard dead?

Hello people. Need help to identify problem. I installed my new 990XA-GD55 with AMD FX-8150. Every part was installed correct and it's worked perfect after one my stupid overclock test... I used Control Center to overclock my computer. All settings i clocked max as possible in Control Center. After that i heared some burst sound somewhere in computeer and after that my computer show black screen. When i turn on my computer, no speaker sound, no other booting. After all bios, battery and other parts clear nothing happens.... What the part may be dead? I think that the my motherboard dead... And also, i can't turn off yet my computer, just unplug power cabel. But to turn on it's possible, but black screen and nothing happens more... :(
My systems was:
AMD FX-8150
MSI 990XA-GD55
AC pro 13 cooler

Hello again helpers. So, PSU is not dead, and with another friends 500W PSU everything are the same. The computer turns on, but black screen, no speaker sound, no boot, no nothing. All coolers work in all speed, case power leds do not shine and also can't turn off computer by the power button just need to unplug power cable. Seems my MOBO is really dead...
Well, this is lesson for me is how to do something crazy but with a little response before I get my best results. Now it will be expensive for me to back to the start. Hope that the other HW parts are ok... Thanks all for the help.
hopefully the other parts are ok, just start by getting a new motherboard as like i originally said you more then likely blew out a VRM or 2 or a capacitor!
in the future don't go so extreme immediatly go 1 small step at a time while overclocking in small incliments and test for stability between! just be careful and monitor what the system is saying temprature wise!

Wont boot at all
all i get is 2 beeps that keep repeating.
I have tried resetting the CMOS via the jumper and removing the battery.
But nothing works!!!
Brand new board today! any ideas?
Cheers

Hey
Right i have removed the RAM and the beeping stopped.
I put 1 stick of ram in and tried it in 2 different slots but nothing.
No beeping.
It wont post. The GFX card spins up then stops and the system just sits there!

990XA-GD55 - USB bluetooth adapter becomes unrecognised if left plugged in

Hello all, I just bought and set up my new MSI 990XA-GD55 (bios 11.2) with an AMD FX-4100 3.6 GHz and I'm having a really weird problem with my usb bluetooth adapter. If I plug it in after Windows 7 (Pro 64-bit) is loaded it's recognized, installs drivers, etc. and works fine, but if I leave it plugged in and restart the machine the next time Windows loads up it shows as unrecognized until I unplug it and reinsert.
The same bluetooth adapter has been used on my old computer and worked fine attached to an internal usb header cable (which is what I'd like to do with this one). Any ideas?

Did windows do an 'auto' driver install? You might need to go to the manufacturers website for the specific driver package. If only a generic driver is installed, it can make the bluetooth unit do what you are experiencing.

It did do an auto driver install, but it's not just a generic driver. It shows up as an ASUS bluetooth adapter and it works when you plug it in while Windows is running, but when you restart with it plugged it it won't work anymore.

990XA GD55 Bios update Failed

Hi, i have a MSI 990XA GD55 and recently i've tried to update my BIOS from versión E7640vN1 to E7640vN2 and now my motherboard doesn't work.
I just downloaded the E7640vN2 bios versión from MSI web site and run on Windows 8 as shown in BIOS flash SOP and the process in Windows finished ok, then the MB reboot and i´ve faced with a black screen.
I have no idea was wrong with it.
What can i do? Can i recovery my bios? Help please !!!!

Figure 1: Error message
The error displays when ...
the update requires certain hardware or software that is not installed on your computer (examples: keyboard replaced with a non-HP keyboard or Microsoft .NET software is not installed),
the computer does not meet a certain minimum hardware or software requirement (examples: 4 GB minimum memory, 200 MB free disk space, or .NET version 2.0 required and 1.0 is installed) .
Usually, this error indicates the update is not needed for your computer and it should not be installed.

FX8150 on 990XA-GD55 voltage question

hello, i'm new there so happy new year to anyone whom read this.
i have bought an FX8150 with an MSI 990XA-GD55, makes like a month, and now im working on overcloking it.
as far as i done it takes this.
anyone can tell me if its safe to go furter, and how
and should i specify other voltage like NB and such.
thanks for answers !

Not really. Voltage is going to vary & spike in relation with the load applied. That is why in many cases it is best to lower the clock some to keep the voltages within safe limits for long term use.
