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...

Turn memory >4GB remapping on, see your manual how to do it.

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,
SL

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.
Quote
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.
Quote
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.

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.
MSI 785GM-E51 BIOS 2.4 (had 2.3 before)

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.

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;

Quote from: Bas on 08-March-10, 21:21:36
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?

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 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 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.

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.

785GM-E51 BIOS problem after upgrading to Windows 8

Randomly (it seems) I can't enter my BIOS or use the F11 key to choose the boot device when starting or restarting my 785GM-E51 based system - but only running Windows 8 or 8.1.
Whenever I wipe Windows 8 off the drive and reinstall Windows 7 I have no problem ever, same when I used XP. But When I upgrade to Windows 8 or 8.1, much of the time (but not always) I can't enter the BIOS, nor is there that message at the bottom of the screen when booting up that says to press esc to enter the BIOS or F11 to select the boot device. This happens whenever I use Windows 8 or 8.1 as the operating system.
I am currently running the latest BIOS, but this has happened with the 2 previous BIOS versions I reflashed as well. Currently, the only way I can enter the BIOS is to reboot sometimes up to 10 times before I finally see that message at the bottom and then I can enter the BIOS, etc.
How could the operating system have this effect on the BIOS?
(Currently I have flashing disabled and also I password protect the whole system with a BIOS password.)
Any help appreciated.
Thanks

Hello again and thanks for your reply,
If that 'Del or F11" message doesn't show up on the bottom line of the screen when restarting before the BIOS prompts me for my system password, you can't enter the BIOS at all, ever. The MSI logo is disabled, but changing that doesn't do anything different either. No matter how many times you press the Del key the BIOS often won't recognize it when the boot drive is Windows 8 or 8.1. You have to reboot over and over (sometimes 10 or more times) until you see that message, then you know the BIOS will recognize the 'Del' key and you can go into the BIOS. Interestingly, what sometimes works when this is happening, is to go into a Windows account, then restart or shutdown. The next time you can usually (but not always) see that message and know you'll be able to enter the BIOS.
I've taken out the memory for another issue, but that didn't change anything. I've tried changing from my DVI monitor cable to VGA (also for something unrelated) and that didn't do anything either. I installed a new graphics card, instead of using the AMD onboard graphics, and that didn't change anything either.
And to be clear, this only happens with Windows 8 or 8.1, not Window 7, XP, linux, etc.
What I do now is I have 2 SSDs, one with Windows 7, the other with Windows 8.1. You can always press 'Del' or 'F11' before the BIOS password prompt appears when the Windows 7 SSD is the boot drive (the only drive). But when you use the Windows 8.1 drive to startup (again the only drive), you have this problem much of the time. And this has been happening since I upgraded to Windows 8 when it was released 2 years ago (8/2012), even trying different revisions of the BIOS firmware (last update 2/2011).

how to solve this?

error in memtest or "Hyper Transport Sync Flood Error" ?
Use normal English, not "r", "u" and such.
What exactly? brand model?
Have you tried with different one?
In which dimm slot is installed?
done >>Clear CMOS Guide<< with power cord removed,
and 'Load bios optimized defaults" ?

yes i already test clear cmos with power cord removed because i afraid get electric shock (im not pc expert)
oh ya found quote in another forum
After reading about 200 threads on this problem, I came to the conclusion that it's a voltage problem. It's not BIOS, an ATI series of video card, faulty CPU or RAM, or a motherboard. The frequency of AMD CPUs being mentioned, power needs, and the ability of BIOS to compensate for voltage changes led me to believe that this is a problem with under-voltage. I don't have the time to experiment with each and every variable, so I upped the voltages in BIOS on all elements of both RAM and the CPU. Before this, I was getting a reboot at random and increasingly irritating times (I do annoying grad homework on this thing). So, after upping the voltages, I haven't had one reboot for HTSFE. If anyone wants to go from here and mess with the individual voltages, go for it. It's definitely a voltage problem. Hope this helps.
so i test it, i upped all voltages that i can change in BIOS. so far its already 2 day without Hyper transport error.
it is fine to upped all voltages?i up it until the highest "white" voltage ( i read in BIOS, grey=auto, white=normal, red=no recommended)

MSI 785GM-E51 no post issues

I can't get this board to display anything and I get no beeps.
CPU is Phenom ii x2 550 and memory is 2x2gb Elipda PC3 10600 EBJ21UE8BDF0-DJ-F. Power supply is a 380w Earthwatts but I also tried another one with the same issues. The thing is that when I don't put the memory in, I still don't get any beeps. I should get some memory error beeps if nothing is in the memory slots, right?
I tried putting only one memory in dimm 1, same issue.
Cleared CMOS. I also took the motherboard out of the case and used the screwdriver method to fire the thing up...same problems. 4 pin CPU power is plugged in. The four phase leds turn on and all the fans turn on, but that's about all I get.
I'm out of ideas.

Quote from: Mark on 31-May-10, 01:21:57
What other components do you have in your PC?
I'm not quite sure that power supply is good enough for your system. Any chance you can get hold of something better, such as the Corsair VX450/550?
Mark...I'm just trying to run it bare bones with nothing attached apart from memory and cpu.
I'll try another power supply.

MSI 785GM-E51 and Athlon II x4

I recently bought a new motherboard and processor for my computer along with 2gb of memory but seem to be having some problems. I have the motherboard connected to my HDTV by the HDMI plug but whenever I turn my tv off and then on again the pc loses its signal and the only way to get the picture back is to press sleep and wake it up or restart it. It also loses its signal whenever I play a game and quit the game. At first I thought it might be a problem with the power supply because the one I was using was only 300w when the recommended said 350w so I bought a 500w power supply but things are still the same. Another thing is that I was hoping to play Mafia 2 on it but when I run the demo it lags a lot even when on low graphics which doesn't make sense since I have whats recommended. Appreciate any help.

With a new motherboard follows a fresh installation of Windows. It is almost a must to get a stable system. But if everything else works except for the gaming, you likely installed Windows on an empty hard disk, and it is as Bas says.
Please list the max amps the new PSU can do. Whenever I read "Cool" my alarm rings.
- Eh, can your system really make it through Mafia 2 with only onboard graphics:
"Video Memory: 512 Mb
Video Card: nVidia GeForce 8600 / ATI Radeon HD 2600"

Need help regarding MSI 785GM-P45

Hi
New to this forum so I will try to give as much info as possible. If you have any suggestions please give as much details as possible since I am new to building my own HTPC
Motherboard: MSI 785GM-P45
CPU: AMD Athlon II X4 640 3.0 GHz
RAM: AVeir 2GB DDR3-1333
HD: EIDE 80GB WD
I installed the cpu and heat sink as well as the RAM in DIMM1 then I attached the power to the mother board. Also attached then box power switch and HDD connections to the motherboard. When I press the power switch on the box I can see the cpu fan turning and box fan turning as well as hear HD spinning (at this point I dont have IDE cable connected to HD). then I attached the display to the mother board and the display does not show anything (displays standby light is still yellow). I power off the system and then attach IDE cable to the HD and then power on the system and this time everything works like before but one thing is different. I cannot hear the HD spinning or powered up. Not sure what is happening. Any suggestion would be welcome
Thanks

You get no display on the monitor?
