870A-G54 VRM cooling ???

Read loads of stuff of VRMs been fried at MSIs boards,so Iam bit scared now, is a good idea stick some heatsinks onto them..??.. any pictures of that, advices?? have I to be worried??

no it wasnt OCed machines, just regular 125W TDP Phenoms. yes ofcourse you cant ask 'budget' (if 80$ mobo could be mentioned as budget ) to make crazy overclock, but "military" components, oc dial, oc genie and all other ""pure OC"" stuff sounds ridiculous if there is such simple problem like weak capacitors and it cant even handle 6core at defaults...

870A-G54 - Cool'n Quiet not working

Hi folks,
I've just got an 870A-G54 ( http://eu.msi.com/index.php?func=proddesc&maincat_no=1&prod_no=2057 ) and have a Athlon II x3 450 in there. I've tried to get Cool'n Quiet working but it's simply not throttling the CPU. Both AMD Overdrive and windows system-panel show the speed to be 3.2Ghz on all three cores despite the PC idling.
- The power-management is set to minimal.
- Cool'n Quiet is "enabled" in the Bios - also tried "auto" to no avail.
- I've installed the drivers from the website. Whenever I try to install them again I get a message saying they're "already installed". I can't seem to find a way to uninstall them (nothing in add/remove panel). I've even uninstalled all my other AMD processor drivers/utilities (i.e. Overdrive), but it /still/ says I have the drivers installed.
Using Windows XP SP3 32 bit.
Note: I have not, overclocked, nor do I intend to.
Any suggestions on how to remove the driver and re-install it? Or, what else may be wrong?
Thanks.

Ok, fresh install of XP SP3 on a separate partition. Absolutely nothing changed from the base install (apart from the mouse-buttons swapped). I try and install the Cooln'Quiet drivers from the MSI website (bottom of - http://eu.msi.com/index.php?func=downloaddetail&type=driver&maincat_no=1&prod_no=2057 ).
When I try and install it, it gives an error saying:
"The machine does not have a supported AMD Athlon 64 Processor".
This happened with this partition of XP too, but I couldn't replicate it so thought maybe it was my memory or I was going crazy. CPU is still reporting 3.2Ghz.
The download page states: "• AMD Athlon™ 64/Sempron™/Turion™ 64/Opteron™ systems". My processor is an "Athlon II". Looking at the date and the version number, the drivers are very out-dated. The other version I aquired from who-knows-where is XP 1.3.2 for XP and almost a year later. The MSI page has 1.2.2.0. The Athlon II's date from 2009 onwards according to wikipedia.
So where do I get current Cooln'Quiet drivers?
Also, as mentioned I've tried both "Optimized" defaults and "fail-safe" defaults in the BIOS with CoolnQuiet enabled. No change.

MSI 870a-G54 Hard drive problem.

About a week ago i reinstalled Windows because it started to slow down (virusses and what not) And as soon as i reinstalled everything (programs games etc etc) One of my harddrives used for games did not show up at the bios and at My computer.
So this entire week i've been trying to get it to work again and i've narrowed down the problem today to the BIOS and/or motherboard not giving the power to the HDD in order for it to start and be recognized in BIOS and Windows.
What ive done to come to this conclusion:
- Reinstalled Windows twice,
- Replaced CMOS Battery,
- Flashed the BIOS to every BIOS setting the MSI website had to offer. None worked for the HDD to get powered up again.
- Moved CMOS jumper,
- Changed SATA and powercables on harddrive,
- Tried the HDD on another test PC i had and reformatted it there as well,
- Only hooked up the not working HDD to the PC, (HDD did not spin up, and came to the conclusion at this point that motherboard or BIOS is the culprit)
- Unplugged the powercable to the not working HDD and plugged it back in when the PC was running and i could feel it spinning up, after this i restarted the PC so that the HDD would still get power and it was recognized by the BIOS and Windows and i could use it. As soon as i shut down the PC entirely and restarted it the HDD would not spin up. And i had to unplug power to the HDD and plug it in again and restart PC for it to work properly.
- Checked for bad sectors nothing found,
Everything else is working perfectly. Except that one HDD not getting the power when booting up the PC.
The HDD in question is the "Samsung HD502HJ 500gig" used for Steam games.
PC Specs:
CPU: AMD Phenom II x4 955 Black edition. Put on a new CPU cooler last summer (Cooler master Hyper 212 Plus)
Mobo: MSI 870a-G54
PSU: Antec EarthWatts EA650 (650 Watts)
Graphics card: Powercolor PCS+ HD5870 Put on a custom cooler last summer (Arctic Cooling Accelero Xtreme 5870)
RAM: Kingston ValueRam 1333Mhz DDR3 (8gigs 4x 2gig) Bought 4 gigs extra last summer
HDD1: Seagate ST3160812 AS 160gig used for Windows 7 Ultimate 64 bit (Works perfectly)
HDD2: Samsung HD204UI 2TB used for Storage / Other games than i have on Steam. (works perfectly) Bought last summer with the cooling/system upgrade
HDD3: Samsung HD502HJ 500gig used for Steam games. (Does not work anymore after reinstal) Bought 2 years ago along with the rest of the PC
I am completely at a loss here as to what the problem is. I do not have the funds to buy a new piece of hardware at this time (i think the entire week of struggle would back that up for me lol...). And ive basically tried everything what i know and what i've found through Google and friends. Might have been better going straight to MSI forum and post my problem here but narrowing it down to this not only helps me but the person that is going to post below in this thread as well lol.
Thanks in advance and i hope to hear from anyone soon.

Try drive in different PC, as it looks like it died.
HDD's always spinup as soon as power is applied, ergo I think the drive died.
Ive tried it already in 2 different PC's and i have to apologize here for not mentioning that earlier in the topic.
The drive spins up perfectly in both of those PC's and ive checked for bad sectors on both of those PC's as well and it showed that the drive was 100% healthy on both PC's
The drive was working perfectly fine before the reinstallation of windows. Thats why i dont think the drive has died. Because it would be weird that the drive just suddenly gave up right when im reinstalling windows..
It also doesnt add up when i plug the powercable back into the drive while the PC is running and it spins up then and works perfectly until PC is shut down. Thats why i had it narrowed down to the BIOS and/or Motherboard being the culprit.
My best guess is that its software related because the PC does boot up so its not a hardware problem.
P.S.
A friend of mine said that it could be a powersaving issue. But ive looked into the BIOS and i could not find anything about it.

870A-G54 rebranded as 870S-G54?

I was poking around inside my computer and noticed that printed on the motherboard was USB 3.0 even though my 870S was not spec'd as having any of them. Then I looked at where my board was branded as 870S to find a sticker over it. Out of curiosity I peeled back the sticker and sure enough underneath was stamped 870A. Can anybody explain this to me please? I have sent a message to CS but have not received anything in return. Thanks!

870A- and 870S-G54 are the same boards apart from the USB3.0 chip on 870A. It's the same board layout, cooling and chipset. As 870S-G54 is a stripped-down 870A-G54 as far as USB3.0 goes it uses of course the same board. Without the USB3.0 it's a 870S. Can't see the problem as it is quite normal.

Does 870a-G54 NON FX Motherboard now support Vishera CPU's after bios flash?

I have the non fx version of the 870a-g54, I have the latest bios flashed on my motherboard right now and in the description of the bios update it reads "- Update AGESA code for Vishera CPU"
So is this support for FX cpus now ?
Is the 870a-g54 FX board the same as the mainboard non fx with just support for FX out of the box?
I'm confused, I would really love to upgrade my CPU, I know my motherboard has weak power phasing so I won't be overclocking at all if I did upgrade.
THoughts?

Quote from: XFM on 16-February-13, 04:59:38
OK, here's a list from MSI I found that support Vishera, if anyone can prove otherwise then go by this list. There is no sense going back and forth without definite proof, as far as I'm concerned the proof is this list.

http://emm.msi.com/display.php?List=75&N=2209
Right there -> 890FXA-GD65 ,white socket , has FX support.So white or black it simply has to be tested and stated to work.
It was stated to work with FX 5 months before the CPU release.And this is just one example
Anyway i would say FX CPU-s SHOULD be used with boards released last year ,just to be safe it doesn t blows up when the CPU reaches some Turbo State.
FX series needs proper VRM stages.

870A-G54 - Possible overheating caused by too much ram? Display driver crashes

Greetings, I have a 870A-G54. I've had multiple issues with several video cards prompting me with a "display driver has stopped responding and has recovered" error. Each video card having it's own unique fix. I've come to the conclusion that it's another piece of hardware in my system that is the root of the problem; and not the video cards. I've noticed that the CPU during "the crash" hits about 60c; usually when playing video games. After a reboot, I can play games for a couple more hours before getting the error again. I'm running 16gb of ram on Windows 7 ultimate. Yesterday I decided to remove 8gb of ram to see if the CPU got "hot" again (only leaving the sticks in bay 3 and 4 in). I had a 4 hour session of gaming and it didn't crash. Note, I have the latest bios installed and a Power Supply that shouldn't have issues powering the whole thing; 850w gold rated PSU. I'm currently running a 6950 video card, and all of the settings are stock; no over clocking in any way. I have a hardware monitor installed that shows with my 16gb of ram that my cpu idles at 41-43c. During a intense gaming session going up to 60c. Yesterday after removing the other 8gb (two sticks of 4gb), it never went above 50c. My CPU is well ventilated. I've contemplated water cooling the CPU if that would resolve the issue. But I'd hate to fork over more money to an already expensive system if I don't have to. I've also wondered if it's just a bad ram stick, or bad ram bay on the motherboard. :\
Any suggestions here would be appreciated! Thanks!

So, I conducted several tests over the last couple of days. Now, I understand that mismatching ram could (and probably is) potentially causing the overheat problem. But... I kind of started looking at fundamentals. I have to sets for DDR3. One pair is Patriot sector 5 ram, the other is a set of Dominator ram. Now, I've noticed that I've seem to always have this driver crash issue. But I had always thought it was the video card. Only until recently I started seeing/noticing that the cpu was getting very hot when the driver would crash. On Wednesday I removed the ram in slots 1 and 2 (the Dominator ram), and only ran with the ram in 3 and 4 (Patriot). It ran fine all night. I then ran some heat tests, with the same ram in bays 1 and 2. When the Patriot ram was in those two slots, it ran cooler. When the Dominator was in, it ran hotter. The Dominator's builtin heat-sinks pretty much rest right next the CPU's heatsink (and restrict air flow). It re-arranged the ram so the Dominators are in 3 and 4. And the Sector 5 are in 1 and 2. It worked all night yesterday, CPU didn't get any hotter that 48c while having multiple programs running. Looking at it now, the design of this MB is pretty bad, there should be a little more space between the CPU and the ram. In any case, I will follow up if it continues to crash due to heating issues. I know it's probably cheaper to get new ram, but I'm playing with the idea of just getting a better heat-sink for the CPU (WATER COOLED)!

870A-G54 Won't post

System has
Patriot Sector 5 2X4 GB 10666 New
GEForce 210 Video card new
Cooler Master 460W New
WD 640 GB HD and now that I list it The HD did go down on a prev. sys build and I recovered info from it, but I don't know if that could be the prob.
Currently I am doing a hard reset. From previous (years ago I found a hard reset over night brought up the system on An MSI board).
Sempron 145
No beeps but all fans and lights work. The board is 870A-G54 Version 3.1

There is no such thing as a hard reset, and switching the reset-switch for a few minutes is enough to reset everything.
However that memory of yours is Intel designed memory, try some el cheapo stick and see what happens.

870A-G54 RAM R/W test failed

Hello
I build a new system for a friend. I tested it for 2 days non-stop, she had the new computer for a week when this error started to appear. Sometimes (not everytime), when you power up the computer the memory count stops at 4096, beeps twice with error RAM R/W test failed. Also it only detects half the RAM installed (4GB) If you press F1 to continue, it boots to windows OK, but sees just half memory. So far I tried reseating all memory modules and swapping first 2 with the last 2. Also tried to disable DCT Unganged Mode. All settings under Cell menu are default, there is no overclocking. Could it be a faulty RAM module? Motherboard problem? Anybody has any ideas?
Here are the specs:

MSI 870A-G54 Blue Screen & Corruption Issues in Windows 7 64-bit

I am having periodic blue screen and corruption issues in Winodws 7 64-bit with my MSI 870A-G54 system. I have a Phenom II X2 560 BE processor, 2 4GB DDR 1333 DIMMs (first bank - unganged), 2 2GB DDR3 1333 DIMMs (2nd bank - unganged), 2 Hitachi 1TB 32MB Cache HDD's in a RAID 0 array, two Galaxy PCIe2.0 GT9500's, 550w power supply, internal DVD drive, and 1 1TB Seagate external 3.0 USB drive. After I load all the supplementary drivers from the MSI site (ensuring I use the 64bit versions), my system becomes unstable. I even tried the new motherboard chipset drivers from AMD (10.12). I am running the latest firmware as well (17.7). The system in not overclocked in any manner and I experience the same results with fail-safe and optimized settings.
I have tried isolating the issue after loading each driver, but due to the random nature of the issue, I am not having success. I have also performed memory and CPU tests that report no errors. Any ideas?

870A-G54 vs. 870A-G54 FX

Hi,
I was wondering if an 870AG54 will support new bulldozers, and now I find that MSI is making such the same mainboard with the same bios, just with black cpu socket, calling it FX, that support new am3+ sockets, and asking 20-30EUR more for such thing..
Any chance to get AM3+ support for "usual" 870A-G54????

Quote from: Henry on 11-October-11, 07:27:15
http://eu.msi.com/news-media/news/1224.html
great news!!
checked stores again, FX version cost approx the same as non-FX version, so hopefully its not just some marketing move, and MSI will support older MoBos with AM3+ bios's - we are waiting for am3+ support to curent AM3 boards MSI!!
at last, bulldozer(FX) CPUs from first reviews is flop so no bother at all att..

870A-g54 front panel audio missing from bios

Boy is this motherboard full of glitches. Teaches me a lesson about buying the cheapest for crossfire.
I would really love to use my front panel audio. Only problem is my front panel audio isn't in the BIOS!
When i bought my 870A-G54 I had to do a BIOS flash to support my six core CPU. Could the BIOS flash have changed my BIOS menu and taken away the front panel audio setting?
Lol does the motherboard even have an option to turn front panel audio on and off?
I had the bios flashed in the store the moment i baught it so i dont know how the bios looked before the flash. The Guy failed to flash my board because he had the wrong bios update and it was too big. So i had to download the right one from msi myself. People like that shouldn't work in computer stores.
My front panel audio has one of those single plug and go audio cables so im shure i couldn't install it wrong, even had the manual next to me.
Am i to be stuck without front panel audio??

Quote from: Stu on 20-October-11, 03:51:31
BIOS does not have any options for front panel audio, it is controlled by the Realtek Audio Manager control panel.
What's the exact problem you're having?
Well i plug in my headphones to front audio and the software should recognize it and light up the ports on screen. But they stay greyed out and i have no mic or audio.
On my old asus motherboard i had to make shure front panel audio is turned on sorry for the confusion.
any idea why it doesn't pick up my headphones?
Ive tried diffrent headphones lol they dont work either

870A-G54 rev 3 Buldozer support

Hi , i'm confussed , i bought 3 month's ago this board , when i choosed this board i entered on msi webpage and i readed "870A-G54" there is nothing about revision , few min ago i entered this page second time and what i have read "870A-G54 (FX)" WT* is going with msi ,they saying that your board will support octa core < then i bought one and after months change model of mobo ?. While buldozer comeout msi will say "teoriticaly" your board support buldozer but the revision NO!. Can i request to change my mobo model to new revision without buying new board , i have 2years varranty and bought document ... (send my board to msi and wait for FX rev of my board) -.-....?

I am not sure what exactly it is you are talking about. I just entered "870A-G54" into the search box of the global MSI website and there is only one model:
http://msi.com/service/search/?kw=870A-G54&type=product
Quote
i bought 3 month's ago this board , when i choosed this board i entered on msi webpage and i readed "870A-G54" there is nothing about revision
Again, not sure what you are talking about. The fact that no revision was mentioned, does not mean that they promised Bulldozer support. What does the one thing have to do with the other. When you checked the CPU Support list a few month ago, I am sure that no Bulldozer CPU was listed in it.
Whatever the case may be, please note that when you check the specifications of the board, you will see a big red note on the top telling you the following:
Quote
The Specification may change without notice. The actual products sold are different from areas. Please check the detailed Specification with your local dealers.

Can i request to change my mobo model to new revision
No. As far as I know there is no new revision. I cannot find anything on the MSI Product pages.
Quote
i have 2years varranty and bought document ...
You have a contract with your reseller, not with MSI. As you live in Europe, the reseller is the one you need to contact regarding warranty & RMA claims. But your board is not defective, so what is the point?
In any case, I checked the BIOS changelogs for your mainboard. It contains fixes like this:
Quote
- Modify some Mojibake in setup menu for AM3+ BOM.
- Add New MP BOM 200 for AM3+ CPU.
- Update Agesa module to support AM3+ CPU.
- Fix system hang on 50h issue when used AM3+ CPU and installed only one memory at DIMM1 or DIMM2.
So, basically, at this point, there is no reason to get angry.
Contact MSI Technical Support directly to find out about the current Bulldozer support status: http://support.msi.com/

Another 870A-G54 not posting

Well, here I am, yet another person with his newly acquired 870A-G54 MB not posting. This is actually my second MB of this series. The first one I RMA'd after it shorted in my case due to a rogue standoff hidden beneath the board; a stupid mistake on my part, but one which I thought I had corrected with this board. I removed all of my standoffs and then put one back for each hole in the MB.
Now the current problem. I put everything together and turned on the board for the first time. The fans spun up, the HDD light came on, and the 4 CPU power phase LEDs turned on. However, neither my mouse nor my keyboard received power, and my monitor remained in standby mode.
All of the parts listed in my signature are newly purchased. They are the hardware that I am using with this MB. According to the MSI compatibility test results, the ADATA sticks, the 8500GT, and the Phenom II are all compatible. This specific Antec Earthwatts was not tested, but a higher wattage one was, and that was compatible as well.
I know my first step is to perform a bench test with only 1 stick of RAM, the VGA, and my keyboard. That test failed, so now I have some questions that you guys can hopefully answer for me.
First: What do the power phase LEDs actually mean? I am trying to figure out if it is good or bad that all four come on and stay on, but the manual doesn't give any description beyond the fact that each LED represents a power phase mode, 1-4. I haven't found anything online that explains this to me. What are power phase modes? What does it mean if all four lights are on?
Second: Could any of my other hardware have been damaged by the first MB shorting out? I know that the VGA and PSU work fine because when I RMA'd the first time, I put my old rig together, but used these new parts in place of my old VGA and PSU. I am wondering specifically if the RAM or CPU could have been scrambled. Just to note, there was no physical sign/damage when the first MB shorted; no smoke, spark, or smell, and there are no signs of physical damage (bent pins, scratches, or cracks) on either the CPU or RAM.
Third: Could this be related to my power supply? Despite the hardware itself being new, the model is old, but it has all of the proper power connectors for this board. Here is a list of the voltage rails and the amps
+3.3 V, 25A
+5 V, 25A
+12V1, 22A
+12V2, 22A
+12V3, 25A
-12V, .5A
Does this power supply not provide enough power to the CPU?
Fourth: Compatibility tests aside, is it possible that the MB doesn't like the Nvidia card? Like I said above, I know that the VGA card works, but MSI seems to favor ATI cards. I have a really old ATI Radeon card that I test with the board, if you think that would reveal anything.
Finally: What besides standoffs making contact with the board could cause a MB to short inside a case?


No Post - Shorting issues
   Motherboard Grounding to case causing No Post
Test the motherboard outside of the case to verify that the motherboard is not shorting to the case and causing a problem
   •    With only the CPU and heat sink, memory, and video card (or onboard video) connected to the motherboard, place the motherboard on a non-conductive surface and retest the motherboard
   •    Check the case mounting standoffs to verify that they are lining up correctly with the mounting holes on the motherboard.
Also try with barabone setup [when testing with mainboard out of PC case], and 1 memory stick only in 1st dimm close to cpu socket.
