MSI 790XT-G45 headless possible?

Hi,
does anyone knows if this board can run without a graphics adapter?
I can buy this board to replace a MSI K9N Neo-F V3 because I need more SATA connections.
Is it possible to disable the graphics adapter/SLI in the BIOS?

I highly doubt that. We are talking about Desktop board here, aren't we? I have not seen the ability to work without a video adapter in many Desktop boards. Server boards, yes. Desktop boards, no (here that kind of ability is rather the exception than the rule).

Th system is suppose to consume as little power as possible.
An onboard video chip does not consume a lot of power.

MSI 790XT-G45 Various Crashes - Frustrated

Prior to purchasing my MSI 790XT-G45 mainboard everything ran great. However after swapping out my old motherboard for this one I experience many various crashes in different games. Here is a list of some games that crash:
Lost Planet (this one worked prior to swap)
Black Site Area 51
Microvolts
World of Tanks
Games that do work:
Diablo2
Minecraft
Monopoly Here and Now Edition
Halo CE
Any Browser Games
I tried variations of drivers etc. etc. and I have even recently re-installed the whole OS and let windows 7 (yes I'm running 64 bit) pick out the drivers. These games that crash run great but then crash out of complete randomness. Lost Planet get's a windows error message like Microvolts. Blacksite get's more spefic error messages but do not tell any clues as to why those crashes happened. World of Tanks usually just crashes to Desktop without warning with a rare occasion of a Windows error message.

I noticed that in the bios it said my cpu speed was 2.97 Ghz while it's actually 2.7 Ghz. I don't think that'd be causing the problem though.
Remove any OC, go to BIOS setup and load bios defaults.

MSI 790xt-g45 - BIOS not loading

Some time ago, a power surge occurred with no preventative measures. The computer was operational during the outage, and I did not unplug the computer. Upon powering on, there is no splash, beep, or anything of the sort. CPU fan is running, and all four APS LEDs are on.
Directly relevant specs are:
Hiper Type R Mk-II 680W power supply; attempted replacement with Silencer Mk II 750W power supply
MSI 790xt-g45 mobo
Is this borked beyond belief, or is there a chance that this may be recoverable?

Start by clearing the >>CMOS<< with the power cord disconnected.
Test with another stick of RAM.
Test with another CPU.
Test with another graphics card.
Disconnect the hard drive/s during testing.
Process of elimination really. By test each component in turn you'll hopefully find out what's wrong. May be worth taking the motherboard out of the case and running it bare bones on a piece of cardboard during testing.

MSI 790xt-g45 chipset driver

I bought a new 790xt-g45 mainboard,installed Xp Pro sp3,when i install the chipset driver a message appears saying-could not find driver for your hardware and os not supported.I'f downloaded the latest driver from msi and still receiving the same error mesage.When i use vista the chipset driver installs. Any one have a answer for me?

You used this driver? http://eu.msi.com/index.php?func=driverfile&dno=2427&i=1

High latency with MSI 790XT-G45 under W7

I have decided myself to go for W7 one one of my rigs.I ve got some genuine disks of 32 and 64 and loaded W7 for testing purposes .
As my intention is to use the 790XT-G45 (considering it more W7 suited than my Platinum beeing newer more CPU support) tryed both W7 versions , but there is a problem.
Using the DPC high latency tool i get like 100 us under any W7 version with this 790XT-G45.The same board is ok latency wise under XP ,it hovers around 10-20 us when you re not doing anything serious with it .I have to remind that on this board i ve also had some issues with the big mouse cursor thing that seems to be related to motherboard latencyes.
In the past i ve used the K9A2 Platinum with W7 64 RC with the same video card and sound card that i use now on the 790XT-G45 ,but the latency was always 10-20 us.In fact trying again the Platinum gives me under W7 like 10-20 us.
I ve tryed disableing onboards ,removing the Creative and updating to latest BIOS version but no joy.The latency also adds some drag to the system i mean W7 windows don t look to snappy like it feels on Platinum.
So is this board compatible to W7 for real ?
What is so different between the 2 boards ,does the 790X have bigger latencyes than the 790 FX from the Platinum.One of the issues is that even if i would choose the Platinum CPU upgrade path closes.
I repeat i ve tested both boards with default W7 drivers and with vendors drivers and same thing.
Any user with 790XT-G45 encountering this under W7 ?
At first glance it s not a very big issue ,but i m very sure this 100 us get s me while playing to more and i really hate input lag and static on my sound.
Any ideas ?

Hi Guys,
I agree with Sm3K3R that a 70+ microsecond increase in average DPC latency will have an undesirable affect on some apps (games, real-time streaming, etc.). I also believe that what is good for XP will almost certainly not be good for Windows 7. Too much of the architecture has changed. Better drivers may help going forward. To me, the bigger question is why this mobo takes so much longer to run these routines than the K9A2.
I do not have any serious problems with the apps I run. Some of them may run better with a shorter average DPC latency. I have no way to tell with what I currently have to work with. Other bottlenecks may be in play. I was just responding to Sm3K3R's request for feedback. My power option is set to high performance and my base configuration has 41 processes running, including Diskeeper real-time defragmenter, Avira Antivirus, Logitech SetPoint, Process Lasso's process governor, PeerBlocker, and TaskDock. It also includes the Microsoft search functions and the sidebar with 2 gadgets running. Most of these processes run as services. I thought it was the search, sidebar, or one or more of the non-Microsoft products causing my base 100+ average latency indicated by the DPC high latency tool, so I ran LatencyMon to find out.
I ran it several times for 2 to 5 minutes at a time, starting when the system was idle. The Nvidia display and NT Kernel & System drivers always topped the list, with latencies from 50 to 114 microseconds. The display driver's routine also ran much more often than any thing else, followed, about 60% less often, by the NT Kernel & System driver. Thus these 2 drivers contribute the most to my average DPC latency. The other products listed above most often had 0 or less than 15 microsecond DPC latencies. Once I saw this, I did not bother to check my game configuration which does not have the search, sidebar, and the non-Microsoft products listed above in it.
During a Google search of this issue, I read that someone reduced their average Windows 7 DPC latency by 50 microseconds by turning off the HPET timer. I tried this and it did not work for me.
Looking forward to the results of Sm3K3R's further testing and feedback from others.

MSI 790XT-G45

I got a problem, I can't set the bios to more then 240 fsb without it going black and refuses to start.
The OC switch is off since I want to reach more then 20% OC with my AMD Phenom x4 9550 CPU
I cant get higher? Or can I change some setting to let go of the cap?
Got a good cooler so dont worry about that!

Windows 7 Ultimate 64-bit (6.1, Build 7601) Service Pack 1 (7601.win7sp1_gdr.110622-1506)
I recently updated Ram and Graphics card several months back. I began having random BSOD and have been trying to track down the issue.
First thing I did was update my PSU from 500W to the current 750W.
Second thing I did was to run a chkdsk. Then I ran Western Digital’s hardware check and the HDD came up fine.
I ran heat check programs to monitor heating issues all came up fine.
Next I pulled half the Ram and ran for several days with no issues. I assumed Ram was bad. Ran memtest 86 individually on all 4 sticks and they all tested fine.
Finally I ran Furmark to test the graphics cards and it stressed tested fine.
I made some queries on some tech forums and this is what I was told:
“Filling all the RAM slots on a Mobo can cause Voltage issues and that appears to be your problem.”
Is this true? Do I have 4 slots but can only use 2 of them? Every single time I put in 4 sticks I get persistent BSOD several times a day. The moment I pull 2 sticks it stabilizes. Is this an issue you can help with?

Hi seanchai,
You can do this. It is a lot of steps, but each one is simple and You Can Do This. :-)
I suggest you start with 2 sticks of RAM. If your system works with the 2 sticks and changed timings,
then install the other 2. Or you can install all 4 to save time and hope for the best.
When you first turn your computer on, hold down the "Delete" key. This gets you into the BIOS utility.
Once there, use your arrow key that points to the right, to move the selection highlight to "Cell Menu",
then press the "Entry" key to select it.
You should now see a lot of options related to your CPU and RAM. Use the arrow key that points down
to move the selection highlight to the "Advance DRAM Configuration" option, then press the "Entry" key to
select it. At the top of the options you now see should be "DRAM Timing Mode". This allows you to select
"DCT 0" to setup timings for your 2 A channel RAM slots, or "DCT 1" to setup timings for your 2 B
channel RAM slots, or "Both" to setup the same timings for all 4 of your RAM slots. Use the "Page Up"
or "Page Down" keys to cycle to the setting you want. I suggest you select "Both", if both your pairs of
RAM have the same timings.
Now the next 4 options correspond to the first 4 timing values in the Timing Table you posted earlier.
CAS# Latency = CAS Latency (CL), RAS# to CAS# = tRCD, RAS# Precharge = tRP, and tRAS= tRAS.
The tRC in the Timing Table is equal to tRC in the list of options. Use your arrow keys to move to the option
you want to change from "Auto" to the value in the Timing Table. Use the "Page Up" or Page Down" keys
to cycle to the value you want. I suggest you use the JEDEC #1 values at first, so that you do not have
to change the RAM voltage values. After you have selected all these values, press the "ESC" key to return
to the "Cell Menu" page of options.
Use your down arrow key to move to the "FSB/DRAM Ratio" option and use your "Page Up" or "Page Down"
key to change the ratio so that the value displayed below this option is as close to "666" as possible (double
the "333" value in the Timing Table). It may display "667", I do not remember.
Use your down arrow key to move to the "Auto Disable DRAM/PCI Frequency" option and use your "Page
Up" or Page Down" key to select "Disable". Then use your down arrow key to move to the "Spread Spectrum"
option and use your "Page Up" or "Page Down" key to select "Disable".
Now press to "F10" key to save all these changes". You will get a prompt basically asking if you are sure
you want to make these changes. Select "Yes" and your computer will reboot and try to use the changes.
If the changes you made are in an "acceptable range", the computer will start Windows, if not it will stay
on the boot up screen and tell you what you need to do to fix things.
Once back in Windows, run CPU-Z and check the memory tab to verify the changes you made are in effect.
Then run your stress test or whatever you did that resulted in a BSOD to see if it still occurs.
Standard RAM frequency, timing and voltages values are set by JEDEC. Non-standard values (EPP) are set
by each RAM vendor for their products. All motherboards are designed to automatically set RAM to the 'best'
JEDEC values the board can support. The JEDEC and EPP values (if any) are stored in a special chip (SPD)
on each stick of RAM. In some cases, if you want to use the RAM's EPP values you have to set them yourself.
Some boards can also be set to automatically use EPP values.
Unless you use the motherboard and RAM that AMD suggests for the CPU you have, you need to sometimes
make adjustments when you use 4 sticks. Sometimes you need to make adjustments even when you use
products suggested by AMD. Most people do not use 4 sticks or buy systems already setup, so vendors get
away with not fixing this problem for the average user who upgrades or setup stuff for themselves.

MSI 870-G45 - something odd is going on with MSI

Ok, this is convoluted but bear with me.
I bought the MSI 870-G45 (MS-7599 v2.x) motherboard from Newegg. Newegg listed the chipset as the AMD 870. However, when I received the motherboard, the manual states that the chipset is actually the RX 780 (a.k.a. AMD 770 a chip from 2007/08!), I checked in CPU-Z and confirmed this. I built a rig with this motherboard on 8/15/2010.
I have been having all sorts of issues. These include memory errors when running memtest86+ or HCI memtest.
Today I come on to the MSI website to do some research on the motherboard and I see that the MSI 870-G45 is now listed as a "NEW" product and the chipset is now the AMD 870, as I originally thought. In fact, MSI has two versions of the 870-G45, depending on what link you visit. See the two links below:
http://www.msi.com/index.php?func=prodmbspec&maincat_no=1&cat2_no=&cat3_no=&prod_no=2070
http://us.msi.com/index.php?func=prodmbspec&maincat_no=1&cat2_no=171&cat3_no=&prod_no=2019#menu
The version I ended up with is the one in the first link.
Now, I have the AMD Athlon II X4 635. The product info page at AMD states that the voltages should be between .85v and 1.25v. ( http://products.amd.com/en-gb/DesktopCPUDetail.aspx?id=625 ) However, even though the BIOS of this motherboard (the version with the 770 chipset, which is the one I got) supports this CPU, the "Auto" CPU voltage setting sets the voltage at ~1.35v - above the specs specified by AMD! Wondering if this might also be a cause of the difficulties I am having, I lowered it to 1.12. Running some more tests to see if this has improved stability.
So, two versions of one motherboard, with confusing numbering and Auto voltage that exceeds the specs from the CPU manufacturer. What the heck is going on?
Another issue is that the manual states on page 2-6 (21 on the PDF) states that to be in dual channel mode, I need to put my two DIMM cards in the slots DIMM1 and DIMM2. However, further down the page under the heading "Important", it states:
In Dual-Channel mode, make sure that you install memory modules of the same type
and density in different channel DIMM slots.
This seems to be contradictory, but it is probably just me. Does it mean I install the two DIMMs in DIMM1 and DIMM2 or DIMM1 and DIMM3?

Thank you both for your input. I mistakenly thought this was run by MSI. Feel stupid. But since you were so kind to respond, I'll post my full system specs as you suggested:
AMD Athlon II X4 635 CPU
MSI 870-G45 AM3 Motherboard
G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (F3-12800CL9D-4GBNQ)
GIGABYTE 1GB GeForce GTX 460
SAMSUNG Spinpoint F3 HD103SJ 1TB 7200 RPM
ASUS DRW-24B1ST SATA 24X DVD Burner
OCZ ModXStream Pro OCZ600MXSP 600W ( +3.3V@25A, +5V@25A, +12V1@25A, +12V2@25A, [email protected], [email protected] )
OS: Windows 7 Ultimate 64-bit.
Also just discovered that there are two versions of my CPU (C2 and C3 revisions). Perhaps that is where some of the confusion regarding voltages lie. Again, feel stupid.
Issues in a nutshell:
Computer ran fine for about 10 days. Then booted up a game and got crazy artifacts everywhere. Windows 7 also showed some artifacts when I went back to desktop. OS never crashed though. Windows has never crashed. Because of this, I suspected that my GPU went bad. Ran OCCT GPU test, Furmark and ATI tool and have artifacts on all three. Artifacts appear immediately upon starting test, so I don't think it is temperature related. Temp of GPU is under 40 C idle and highest under load is 77 C, which falls in line with what I read in reviews for card.
Now, before RMAing by video card with Newegg, I decided to download memtest86+ and run it. Just a hunch. I got an error on the first pass in test 2. However, I continued to run the test and saw no more errors. Ran the test again overnight for hours and could not recreate error. Thinking I may have gotten a false positive, I ran HCI Memtest (this one runs in Windows) and ran it for a few hours. That reported multiple errors as well. Now I am trying to run the test with one DIMM at a time to see if I can isolate which stick it is.
So I guess my questions are:
* What are the chances that I got a bad GPU and bad RAM from Newegg? Anything is possible but I thought that getting two lemons was unlikely, and when I then saw the discrepancies in the motherboard info on MSIs website I started to wonder.
* Could bad DRAM have any effect on GPU - as in displaying artifacts. Or would this strictly be a GPU issue?
* A member at another forum warned against leaving voltage settings in BIOS at Auto. This is what led me to look up the specs at AMDs website. What do you think about this recommendation.
Sorry if I came off a little harsh, I thought I was addressing MSI the company and was a bit miffed by two different versions of a board and with the fact that newegg was improperly stating the specs.
I appreciate any help you can give.

Dont know what graphic cards to get for 790xt-g45

Hey everyone. Im new around here and had a question. I have a computer with a 790xt-g45 motherboad was was going to upgrade my graphics card. I wanted to get 2 1gb cards but cant deside if i want to go with ATI or Nivida. I have a Nivida card now but I read online that this board is crossfire ready. Is it SLI ready too or is that just what MSI recomends? Any advice or info would help. Thanks!

Thats kinda what I got from everything I have read. If its says crossfire ready and nothing about nivida slr then its only ATI crossfire. Just wanted to make sure before I pick out a nivida card, order 2 then find out the board will only work with ATI crossfire and return and order something else. Thanks for the info!

790xt-g45

Ok I bought a 790xt-g45 board a while ago and I've been using a AMD Athlon 64 X2 6400+ BE for a while and I want to upgrade I bought this boarding reading on newegg and the box that it supports AM3 sockets. When I go to the support page it doesn't list any AM3 sockets, do anyone have any insight as to what AM3 cpu's work with this board?

Hi,
Follow Mike's advise. I got my 790XT-G45 last June and have been using it with my P2X4 945 every since with 0 problems. This is a 4-core AM3 processor and I have been running at stock speed (3GHz) with Cool 'n Quiet or with a 20% (3.6GHz) overclock without Cool 'n Quiet (needed a 0.05v CPU power boost for stability). I'm using a Cooler Master Hyper N520 CPU cooler, which does a good job keeping my processor core temperatures down while running the cooler fan at half speed (very quiet).
Except for the number and control of system fan headers, I am very happy with this mobo (the BIOS-based CPU cooler support is great). I solved my system fans (front, side, and back) issue with a NZXT Sentry-2 fan controller (5 3-pin headers with independent temperature sensor-based controls for each one - highly recommended).
I have also been using the 2.5 BIOS since it came out, last August (sorry Mike, couldn't resist trying it). Sm3K3R, what DRAM settings and possible USB issues are you referring to in the 2.5 BIOS? My DRAM has a standard CL5 mode (1.8v) and an enhanced CL4 mode (1.9v). I'm able to setup up either one in the BIOS. I also have not had any problems with my USB devices (multifunction printer, keyboard & mouse, camera, and MP3 player). Don't know if it matters, but I also keep my mobo and device drivers and OS updates at their latest versions.

Msi 970a-g45 won't enter setup

I just put together a brand new system. Components are as follows:
MSI 970A-G45 mobo
AMD FX 4100 3.6Ghz
GeForce GTX 550-Ti video card
(2) 2GB DDR3 1600 memory
When I first put this system together, I set my 3 hard drives as a raid 5 and then proceeded to install windows. First it told me I needed a dvdrom driver which I thought was funny because that's what the windows disk was running in. I restarted several times and I got a boot failure and when I restarted it again one of my harddrives disappeared. After unplugging and replugging several times I finally got them all to show up again but then it wouldn't let me back into bios. It froze several times at the entering setup screen. I tried resetting cmos and no results. I pulled the memory down to one stick and got into bios again but it hasn't reset anything other than the date. Windows 7 boot disk still won't run and I don't know what else to do with it. I have used this disk to recently set up 4 other computers and have eventually gotten all the other bugs worked out. What else can I do to insure that this will work?

Use as few components as possible when installing Windows: No doubles or extras or other unnecessary things. Add the unnecessary things afterwards.

MSI Z97-G45 Gaming can not POST or enter BIOS but has display

Hi
First post here and sadly a technical one. I just bought the following hardware:
- MSI Z97-G45 GAMING MoBo (no idea on BIOS since I cannot enter it at all)
- Intel Core i5 4690K s1150
- 16GB (2x8GB) Patriot Viper 3 Black Mamba 1600MHz CL9 DDR3 Dual/Quad Channel Kit [PV316G160C9K]
- Corsair CX750M PSU
and installed the hardware with the following old hardware that I am carrying over:
- 2 X Hitachi 1TB Sata HDD
- 2 X GTX 275 SLI
To begin with, my existing drives were setup as RAID 0 and has a installed Windows 7 64-bit on there already. I unregistered the Product key before taking it all apart with the idea of registering it again once the new hardware was all together.
So basically, when I received all the new parts yesterday and put them all in. Upon powering on, I see the MSI Dragon logo fullscreen with the option to press DEL or F11. I let it continue without pressing any key to see how it goes. After the dergaon logo, all I get is "Missing Operating System" at the top which did not really worry me and I assumed it would be realted to the Raid not setup (right?)
So I rebooted the PC and decided to press DEL to enter BIOS. However, every time I want to enter the BIOS the screen turns black! The display is still functional though from what I can tell (the display does not lose signal).
Following that, I reset the CMOS from behind by pressing the button with a pen tip. Starting the PC again now gives me a display of all my hardware that it detected (correct CPU, Correct amount of ram, correct HDD etc...). It also gives me two options... F1 to Enter setup or F2 to Continue. Pressing F1 displays the text "Entering Setup..." at the bottom but again it fails to enter the BIOS (it freezes on the above screen - does not turn black this time) and choosing F2 to Continue freezes as well.
I have tried to boot up with the following changes:
- No GPU and use on board VGA only
- One stick of ram in multiple slots
- No HDDs connected at all
- I've checked the CPU to make sure no bent pins
- Reconnected the PSU cables into the motherboard
I should also mention that when I test it on the bare minimum (CPU, PSU, 1 stick of ram) I get A9 in the lower corner before the dragon logo appears.
Right now I am out of ideas and any suggestions would be helpful or at least some insight in what problems I described may indicate. Thanks!

Can you post your board's serial number. This contains the manufacture date. From that one could deduce the BIOS version on that board.
As for the windows installation from your previous system, you would be very lucky if you were able to boot with that. Perhaps force safe mode if and when you are able to boot, and then try installing the new drivers. The problem is that with the old drivers still in the boot menu, you are probably heading down a slippery slope trying to re-use it. A clean installation would be advised.
Whatever is on the HDD now should however not prevent you from getting into the BIOS.
The fact that your CPU is recognised by its make doesn't mean that its supported. The CPU ID is probably read by the BIOS, but the microcode of the CPU may be missing in the BIOS support. I am trying to think of possible reasons here, and these are just some of my current ideas as to why you may not be able to get into the BIOS.
Have you tried your MB outside the case yet, i.e. on a non conductive surface, i.e. wood or cardboard to eliminate any chances of a potential short?
Also, you may want to check your CPU seating again and carefully inspect the CPU socket pins to ensure that none were bent or are not making proper contact
Yep here is the serial number: 601-7821-050B1405415963
Yeah I didn't really expect to have too much luck with the original windows 7 installation but I had no choice since my last computer failed to power on (faulty PSU I suspected).
However, as you also mentioned, I do not think it would prevent me from reaching the BIOS setup.
Hopefully the above serial can make some sense for you but I do recall some sort of date after a CMOS reset at the top... I think it was 21 April or May 2014 or so. This was next to the following: E7821IMS v2.0.
Once I get home, I will try a few things like you suggested but trying to get as much info as I can before I get home so I have a few things to try.
Thanks again!
EDIT - as a side note, I also contacted the Online Retailer I got it from and the first response from them was that the DEBUG "A9" code meant it was the RAM not fully inserted. That is another thing I have to be 100% sure of but I am fairly sure it was fully clicked in on both sides... but you never know!

MSI 790XT-G45 headless possible?
