MSI 785GM-E51 - onboard LAN not working

Hello,
I've problem with MSI 785GM-E51 board. Suddenly, when I booted system (Ubuntu) I've noticed that there is no network and even network device (lcpci showed no network devices). Is it possible that the onboard LAN got damaged? I tried to check BIOS and renabled oboard LAN/remove PCI devices/unplug power for a few hours etc but nothing helped. Any suggestions?

LAN card has worked earlier?
PSU is starting to fail? If things work after several re-boots that may very well be the reason.

Got a problem with BIOS in my board MSI 785GM-E51

i have a MSI 785GM-E51 board,i got a problem with the graphic card bus interface,it still run in 8x not in 16x
i try to disable a onboard graphic on BIOS,but i not find it.
and last i try to update BIOS to v2.4 n' not work too.
this a example;

You do not need to disable the onboard.
As for the plug-in card, there is nothing in the BIOS to make it work 8x or 16x.
Make sure your card is seated correctly, else it will work but at lower number of lanes.
What program is telling you it's 8x?

MSI 785GM-E51 Fails POST

I have built a new machine with the following Specifications: (All new parts)
Mainboard: MSI 785GM-E51
RAM: Crucial Ballistix sport 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 Desktop Memory Model BL2KIT25664BA1339
CPU: AMD Athlon II X3 455 Rana 3.3GHz Socket AM3 95W Triple-Core Desktop Processor ADX455WFGMBOX
PSU: CORSAIR Builder Series CX430 V2 (CMPSU-430CXV2) 430W ATX12V v2.3 80 PLUS Certified Active PFC
Hard Drive: Western Digital Caviar Green WD6400AACS 640GB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive
This build initially started up but then failed POST. I am getting what sounds like the normal beep followed by two short beeps and then nothing. Earlier in the day, it started up and I reviewed the BIOS settings. Shut it down and moved it from one work bench to another, inserted the O/S CD and tried to start it. Would not pass POST. Nothing had changed from when it started only a few moments before. I have removed all expansion cards and the CD drive. Disconnected everything from the main board except the RAM and the hard drive. Reseated the RAM. Tried only one stick, twice. Still the same POST of one beep followed by two rapid beeps. Using onboard video. Tried VGA and HDMI connections.
I have build many computers but this one has be stuck. :(
Any ideas? Thanks

Excellent advice on this forum. Thanks to all. Up and running fine now.
I had some small washers in my shop so I put a small washer under each of the standoffs. This raised the motherboard enough to prevent any shorting.
The advice on the toenail clippers was good. Would have done that had I read the note in time.
The "two many standoffs" is also good advice. I made that mistake once early in my building career. Especially important when upgrading.
Again, Thanks to all,

CMOS Checksum Error on MSI 785GM-E51

Hi, I have 2 years old MSI 785GM-E51. Approximately 2 - 3 months ago, my PC just go hang without any reasons, even the mouse / keyboard won't respond to anything.
After I reset, sometimes it's fine, but sometimes it's hang again, the interval is random. Sometimes it even hang when in the POST or when i enter BIOS setting.
After several restart, it's sometimes gives me CMOS Checksum Error, so I decided to reset the CMOS using jumper method. After that my PC just works normal.
Until a week ago, my pc start to hang randomly again, the symptom is similar but this time sometimes it's not hang, but the PC just restart immediately with black / white / blue random pattern
displayed momentarily on the screen. And it always display CMOS Checksum Error. I already tried reinstalling Windows, and updating BIOS via flash disk from Live Update 5, no use.
I already tried to plug out my VGA and using the onboard one, still crash / hang randomly. I also test Memtest overnight with passing 11 pass without error.
Is it my motherboard already dead? or it's my PSU? CPU?
Here is my complete specs:
AMD Phenom II X4 955BE
MSI 785GM-E51
DDR3 Dual Channel 4GB RAM (corsair, forgot the model)
Radeon 5770
WDC 1TB
WDC 1.5TB
Amacrox Free Style 650W
Thanks in advance.

Yesterday i desperate enough and change some BIOS settings, and
surprisingly, the CPU is much cooler!
Try entering bios, hitting f6 for optimized defaults then save and exit. See if problem persists.

As far as I remember, no, the crash / hang time i remembered is when POST / boot / startup / browsing / install app / playing games / copy file.
And one more thing, when it hangs, it really hangs, not just the windows, sometimes it even not respond to reset button, so i have to power it off. But sometimes it respond
to reset button, but with quite a long delay, it could half a minute i think.
Have you tried re-seating the cpu,memory and all of the power connectors etc?
What are the amp ratings on the 12v rail of the PSU? I found this on thier website but dont have time to dig furthur: Quote
4-Channel 12V Rails Design
Although the VGA you list only needs 24a on a 12v rail.

what's cpuid / ram timings / spd? where i can look at it?
http://www.cpuid.com/
When the program opens, take a screen shot of the tab that describe how your ram is running, It will show the current timings,speed, single or dual channel. Also take a ss of the spd tab, which will show the jdec standards that apply to that ram and the xmp profile. Then post the SS's to imageshack or the link and link them.

MSI 785GM-E51 can't install audio drivers

Hey, I would be grateful if you could help me with this problem.
When I try to install the audio drivers of this mobo(785GM-E51), Windows 7 can't find them. It offers me another set of drivers - that of VIA's, but it should be Realtek's. Normally it wouldn't be a problem, but I have a an issue with front panel microphone jack(it's not working), so I want to install the proper drivers. I tried disabling auto-installing option of Windows 7, and then install the drivers that MSI offers officially , but still the computer acts as if I didn't install anything.
EDIT: It seems that I have a different motherboard - in the document I have(about the parts of PC), it says that the computer has MSI 785GM-E51, but now that I checked the informationa about motherboard in the Windows itself, it appaars that ASrock M3A770DE is in the case. So I guess the fact that I can't install the MSI's drivers is because of different mobo. I have no idea how this could've happened.

>>Posting Guide<<
Why don't you open up a case and read the model? Is the computer secured with some sort of sticker that voids warranty if opened?

MSI 785GM-E51 and memory modules problems

Could anyone help me with one problem. I have motherboard MSI 785GM-E51 and 4 memory modules GOODRAM GR 1333D364L9/2G. But when I'm inserting ALL modules my system not starting (even POST procedure). So working variants - when I'm inserting:
- one module in first (boot) slot
or
- they inserted in first and third memory slots
Any ideas?

It is not motherboard problem, but processor itself - I have AMD Phenom II X4 965 Black Edition 3,4 Ghz Core Revision C2 and this revision (according to the article: http://www.fcenter.ru/online.shtml?articles/hardware/processors/27650#02) has problems with support memory modules DDR3-1333 Mhz more than 2 modules. Conclusion - either adjust BIOS settings concerning memory timings and memory controller voltage or replace this kind of processor with the same type but with core revision C3

MSI 785GM-E51 - Amount of usable RAM in Windows 7 Ultimate 64bit

Hello i have the following system:
Mobo: MSI 785GM-E51
Bios: AMI v 2.3
CPU: AMD Phenom II 955 BE @ 3.2Ghz
Memory: 2 dimms of ( KINGSTON KVR1333D3N9/2G DDR3 2GB PC10666 1333MHZ VALUE RAM ) , Total 4Gb
GPU: Sapphire Radeon X1950 Pro with 256mb RAM
OS: Windows 7 Ultimate 64bit
The specific motherboard has an onboard ATI 4200 vga. I've installed the Radeon x1950 pro from day 1 and in the bios settings the onboard vga option reads disabled. However windows 7 during install always recognize both x1950 pro an 4200 and provide drivers. In windows device manager i have the 4200 disabled. However windows display that from the 4GB of installed ram only 3,75GB is usable. Is this normal? Isn't supposed to have all my memory available since the onboard vga is disabled? And if it is disabled from start how windows 7 detect it during installation and suggest corresponding drivers ? I'm looking forward for your opinions and suggestions
Thanks in advance...

System unstable - MSI 785GM-E51 and OCZ3G1600LV2G

I had random freezes since I built the system(20 days ago). But, intially freezing up once a day or so. Recently in the last 10 days, the freezes are more often (sometimes within 5 to 10 mins). Basically system freezes at stock settings.
Running Prime95 to test
Blend test stops mostly within the first few seconds reporting hardware error. The other two types work well. Did not let them go past few mins.
Also, changed the CPU to FSB ratio to 1:4. So, BIOS indicates 1600Mhz. Changed DRAM Voltage to 1.65V and system still unstable. Changed back.
Also, when I enable the MSI board features to Unlock CPU and ACC, the sytem does not boot under and stock settings.

OCZ3G1600LV2G
The model number is incomplete (not possible to find any match on the OCZ Product Pages).
Can you write down the model number as it appears on the modules themselves?
Quote
Voltage 1.5V (Mfg specs.. say 1.65V)
Those 1.5V do not indicate the voltage set in BIOS but the JEDEC Compliant default voltage for DDR3 modules (1.5V +/- 0.075V). 1.65V is an overvoltaged rating that is needed to compensate the overclocked/undertimed ratings OCZ adverises for those modules.

Re: MSI 785GM-E51 and memory modules problems -l- Split

I am using AMD PHENOM II 1055 125w CPU on MSI 785GM-E51. Memory Corsair XMS3 DDR3-1600 x4
I can put memory in slot 1 and 3 it will boot fine.
If I install DDR3 in slot 1 and 2 the system will not boot. If I full populate all the memory slots it will not boot
In both scenario's after the system does not boot and go back to just using slots 1 and 3 the system boot with CMOS checksum error and need to go in to BIOS setup. All the changes need to be made again, saved and exit and it reboots fine.
I have already attempted to setup the memory speed to 1333 and 1066 with no luck. Any ideas?

MSI 785GM-E51 coaxial?

Hi,
I've bought a HTPC based on MSI 785GM-E51. I haven't noticed that this motherboard has only HDMI and 6ch output for sound. I've A/V receiver with no hdmi-in connector. My question is if one of 6ch outputs is coaxial?
Sorry for my english - haven't used it for years.

I presume you bought this system prebuilt then? If the system builder did not provide the mainboard manual, you can download it from here:
http://eu.msi.com/index.php?func=downloaddetail&type=manual&maincat_no=1&prod_no=1866
The S/PDIF bracket is an optional extra with this mainboard. You can ask the system builder if they have any available, or you may be able to find one elsewhere.

G31TM-P21 Onboard LAN Wont Work!!!!

I have read. I have searched. I have spent almost a day on this. It has to be easier than this. I had a wireless card. I had to move computer. It doesn't receieve the wireless signal that well anymore. I say "I'll run a cable and use the on board LAN". I bought a new cable. Before I started I checked it (worked properly). Then I disconnected and uninstalled the wireless card. Downloaded the drivers for the mobo LAN (I have no idea where my disk is?).
I have it to the point where the computer is recognizing the PCI-E family controller as the Network adapter but it says the cable is unplugged (it is not and has been triple checked). It also wants to install a PCI device and SMS controller (I can't get these to install at all - it rejects all drivers I throw at it). I have the drivers from MSI. It didn't take them.
Windows XP SP2
G31TM-P21 mobo
in Set up I have on board LAN enabled and LAN ROM enabled
PCI-e graphics card (I don't remember which one and I'm too frustrated to go look)
Am I missing something simple?? I usually can solve all my computer problems after this amount of time. I'm severely frustrated (this typing did help though). If I need to post more info let me know.
I need to go take a walk.

I'll check the cable again. But I still can't get past this phantom PCI device it is finding. So when I switched to onboard LAN it found 1.) PCI-e Family 2.) SMS Controller and 3.) PCI device. I have gotten the drivers to taken for items 1 and 2 (I found the install disk) but for the life of me I can't get the third thing (the phantom PCI) to install. It is not giving me any clues what i need either.
I'll try again tonight but any help wouldbe appreciated.
I did this on one of other computers last year and all I had to do was change it in the BIOS. No install. No drivers needed. Why is this so complicated.

MOVED: G31M3 V2 OnBoard LAN - WOL works Intermittantly

This topic has been moved to Intel Core 2 Duo/Quad boards.
https://forum-en.msi.com/index.php?topic=149866.0

Last year I lost interest in this problem after getting nowhere. Now I'm keen again to try to get WOL working on my computer.
I've re-read this thread and everything I wrote initially is still the case and the problem.
The last reply I had was from 'Cronnin' suggesting checking bios setting.
As I stated in my original question/problem I have enabled 'wake on PCI-E', 'wake on PCI (PME#)' in bios and tried with one or the other enabled and with both enabled.
1: The computer starts from 'shut down' S1 mode via a 'magic packet' if I send the 'magic packet' within a few minutes of shutting down, therefore I assume all addresses, port-forwarding, wol bios settings etc are correct
BUT
2: Sending exactly the same 'magic packet' after the computer has been shut down for 1/2 hour or more will not turn it on.
The thing that I still think points to the problem is the fact that the green led on the onboard LAN NIC goes off when the computer is shut down (S1 mode). It also goes off when 'S3' mode is selected in bios.
Incidently, in both those shut down modes the 'num lock' led on the keyboard is still on so I gather the PSU is still supplying 5V to the mainboard.
I'm leaning to the idea that the problem is a fault with the motherboard or on-board NIC. Does anyone have any other suggestions?
Thanks in anticipation.

G31M3 V2 OnBoard LAN - WOL works Intermittantly

I've set up G31M3 V2 mainboard using on board LAN (Realtek RTL8139/810X) to wake on lan via internet/cable router from the power off mode.
When I shut down the target (remote) computer I can restart within a few minutes using a 'magic packet' (so I assume all router port forwarding and LAN settings are correct). But, if I leave that target computer switched off for half hour or more I can no longer start it using the 'magic packet'.
I'm guessing that charged capacitors are allowing the restart after short power off time but are discharging and preventing activation via LAN after a period of time.
This would mean that power is not being supplied to LAN when computer is shut down. Is there a setting in BIOS that I'm failing to see that ensures power remains applied to LAN board when computer is shut down (but still plugged into power) Could it be my actual Power Supply?
I have wake on PCI-E & wake on PCI (PME#) enabled in bios.
Any thoughts?

H55m-E23 onboard lan doesnt work

i have an h55m-e23 mother board and the on board LAN stop working after 12 hrs. id looked in the bios to make sure that it was enabled and it was. i also tried to reinstall the drivers for it but it said that the device can not be found. is there anything else i could try.
my computer specs are as followed:
atx power up mid tower case
Intel i3-540 (3.6ghz)
4GB ddr3 ram
450w PSU
msi h55m-e23 mobo

When you said the LAN stopped working, does the LEDs on the LAN port still blinks?
Is the Ethernet LAN Connection still detected in Network connections? How about Device Manager, is the LAN chip being detected?

5.1 Soundblaster not working, now LAN not working eith

Hi,
I'm new here, and would greatly appreciate any help anyone can give me. I've tried searching and looking through all the FAQ's I could find, but still am not able to find a solution.
I am running windows XP and I have a Soundblaster 5. card, and it's worked perfectly until last night. I had my headphones plugged in, and decided to plug in my Creative speakers instead. When I tried to plug the speakers in, soundcard appeared to be not working. I opened up my computer and took out the sound card and put it back in again, thinking I had maybe knocked it loose. I then went to check it under Windows device manager and it was listed as 'Multimedia Audio Controller" and said I had no drivers installed. I came here to the website, typed in the model number, got the correct drivers, but when I try to install the drivers, I get an error message saying that there is not a compatible device installed. I tried removing the card and putting it back in, also tried putting it into a different slot, but to no avail.
Now the biggest problem; after plugging my sound card in for the 4th time, my network connection stopped working. I'm connected to a LAN, and it keeps saying it's unable to renew my IP address. In device manager, it doesn't look like there's anything wrong with my network card.... could it be possible that I somehow fried the on-board network card when I was putting the sound card in?
I'm really at a loss as to what to do here. ANY suggestions at all would be GREATLY appreciated.
Thank you very much in advance.

Just downloaded a new driver for the realtek HD, will this resolve my problem? Current driver version is 6.0.1.6657.
Your issue is drivers related.
For Windows 8 use 6.0.1.6839
