MSI Z97 G45 Ethernet random disconnections

Hi,
Roughly 2 weeks ago, a built a new PC for myself, and I have had Ethernet issues ever since. The build in itself is pretty standard, and I use an MSI Z97 G45 motherboard to support the thing.
My problem is that I get disconnected randomly while I'm using the Internet (and maybe when I'm not, but I haven't noticed it). I haven't seen any pattern that could explain the problem, I'm not heavily using the network (at most a Mumble connection + EVE Online for instance), and it has happened when I was only browsing the Internet.
I have tried uninstalling the driver and installing the latest one, or the same but with the "driver only" option, and it still happens.
I must say it is quite frustrating, so i anyone happens to have any options. I have read that it could come from the Killer Network suite but I have uninstalled it and the Qualcomm thing does not appear in my installed programs anymore, so there's that.
Thanks for your time

I'm using a PLC going straight to the wall, and out the wall to my router. I have used several computer on this connection and I have never had a single issue.
You are right about your second point, I'm only assuming it, but the indicator on the PLC stays green even when the connection disappears and rebooting the computer solves the problem every time, so I figured it comes from the machine itself

Difficult overclocking i7-4770k on an MSI Z97-G45

Hi,
I have tried some very modest overclocks with my machine, but it does not seem to like it very much at all (random reboots etc).
I posted in the sticky thread about the G-SKILL RAM, and tried some suggested timings (DDR3-1333 9-9-9-24 @ 1.50V), but I still had problems (random reboot happened a day or so later).
I am now back to complete defaults for everything, which seems to be the only configuration that has not yet crashed. I'm quite new to OCing, so can anyone point me in the right direction for troubleshooting this?
For reference, my hardware is as follows:
- MSI Z97-G45 (BIOS is the default that was installed when I bought it ~July).
- 4 x 8 GB G.Skill Ares DDR3 1866
- i7-4770K
- Zotac 4GB 770 GTX
Thanks!

My suggestion is update to the latest BIOS since it's improved RAM compatibility.
And see this compatibility report for OC memory, but crucial only tho..

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 Z97-G45 Smart fan control Bios v2.0 vs Bios v2.3

Hello
I have an MSI Z97-G45 Gaming motherboard in my new setup with 4ghz i7 4790k and 16gb of ram and so on that i bought a few weeks ago. At first the motherboard had v2.0 Bios and everything worked just fine but as i like maximum compatability and other fixes i upgraded the bios to the latest one v2.3.
In my setup i use the bios smart fan control for both system and CPU fan, i set it at a curve where the fans instantly will rise the fan speed when doing tests like Prime95 and Aida64. When doing the tests the fan rised from idle 800rpm to neded fanspeed for the correct cooling for my CPU and reached maximum 1500rpm in a matter of seconds to keep the CPU cool. This worked perfectly with Bios v2.0 but after i upgraded the bios to v2.3 the smart fan control changed fanspeed extremely slowly, it took almost 50sec for the fan to speed up from 800rpm to 1500rpm when stressing the CPU at 100%. When i stoped the stress test the fans slowed down to idle 800rpm very fast with bios v2.0 but with bios 2.3 i took a looong time to slow down to idle speed again from 1500rpm.
Because of the slow changing fanspeed in bios v2.3 i downgraded to v2.0 again and then my fans works just as i want them to do.
What is the reason for this problem/change in bios v2.3 and will this be fixed in future versions? Is this a known problem with newest bios?
When people will buy this MB and it has v2.3 from factory the smart fan control will not work properly and buyers will not know how good it can acctually be. I think the Smart fan control in v2.0 is super great

MSI Z97-G45 Gaming VS MSI Z97 Gaming 5

Hello there!
As I received much of good help on these forums already, here comes my next help request. I will have to decide which motherboard should I buy soon (upgrading to Intel Core i7 4790K), I have done some research and found out that these two models I mentioned in the thread subject would be of my main interest. I am, however, a bit uninformed, as I could not find any test of MSI Z97-G45 Gaming. I have a few questions about those two.
First of all, Z97-G45 has a fast boot in official specification on MSI Global and Gaming 5 does not say anything about it. Does it mean that Gaming 5 boots long? How I should understand that?
I think Z97-G45 looks better, that red dragon is really fancy, however Gaming 5 laminate looks more black, which makes it also atractive to me.
All that I really need to know is, which one of these will perform better for CPU overclocking? Is there any difference at all? The price is really simillar. I also see that G45 does not contain an M.2 and neither of them got Sata Express. Could anyone explain if Sata Express or M.2 are really worth having them right now? Will M.2 improve my current SSD speeds? And Sata Express will improve my HDD speed? Or how does it work? Will it only boost up drives that are particularly made to work with those connectors?
Thanks in advance!

All modern mainboards support fastboot as it is a Windows8 feature.

Z97 Gaming 5 is the more modern board. It offers more ram speed dividers. M.2 is pretty much standard for Z97 boards so G45 is more an option for those still willing to use slower msata devices. Of course M.2 is only any use for you if you are using a PCI-Express based (!) M.2 SSD. If you buy such an M.2 SSD (e.g. Plextor M6E) then it will speed up data transfer a lot as SATA 6GB/s limits latest generation SSDs already. M.2 on Z97 boards being PCI-Express based is running directly through PCIe lanes to the CPU while throughput of SATA is limited by the SATA interface. SATA Express being a similar technology is not supported by both boards but devices are also not available really.

MSI Z97 G45 Motherboard (CPU / RAM PROBLEM)

Hey guys! I recently built my first PC and need some help! I'll list my setup before elaborating.
Case = NZXT H440 Black/Red
MOBO = MSI Z97 G45
CPU = i7 4790k
RAM = TridentX 2400 (16GB)
PSU = Corsair AX 760 Platinum
GPU = MSI GTX 970
SSD = Samsung Pro 850
Okay so basically after I finished the build and fired it up everything worked GREAT! But, I realized the DRAM was only running at 1333 mhz by default. I did a little research and read that you're suppose to enable XMP Profile 1 on this MSI MOBO in order to achieve the 2400 mhz this memory offers - so that's what I did! However, this caused the CPU to overheat! Apparently XMP overclocks the CPU as well? Bad! I'm on stock cooling. It took me forever to figure out that it was the XMP that was causing the overheating too.
How can I achieve 2400 mhz WITHOUT overclocking the CPU and frying my PC? Why do I have to overclock at all? The ram is sold as 2400 and suppose to be compatible with my motherboard, processor, etc.
Please help!

Memory speed is down to how your computers CPU's Memory controller handles the higher frequancy and if the CPU sees that the IMC is suddenly loosing a hold it will boost up the Voltage on the IMC (More voltage = More Heat) its a total shot in the dark that any CPU can use above its listed memory speed without needing more voltage to be stable!
your CPU's IMC will be overtaxed by running at 2400 so the voltage is increased to use that as the speed is at 150% what the IMC was rated at (1333/1600Mhz)
for your 4790k
Memory Specifications
Max Memory Size (dependent on memory type)    32 GB
Memory Types    DDR3 1333/1600
Max # of Memory Channels    2
Max Memory Bandwidth    25.6 GB/s
ECC Memory Supported ‡ No
if i was you its always a good idea to get a aftermarket cooler as the intel stock ones are very poor and are just barely enougth so the best thing to do is get a better one (e.g. a Coolermaster Hyper 212) that has a higher cooling capacity for not that much money!
that ram is putting 150% its design load on the IMC so it will be generating more heat then it was meant for so you need better cooling if your running those high OC memory sticks!
So what happens if I turn up the frequency to 2400 mhz without using the XMP profiles? Will the CPU still overclock? I know the memory needs more voltage at higher frequency, but what about CPU? Sorry I'm new to all this it's a lot to take in.

MSI Z97-G45 Sound Issue

I bought a MSI Z97-G45 two weeks ago, everything is working fine except for the sound. The problem is when I plug my 3.5mm jack into the motherboard it does give sound, but a very low volume. When you turn the volume up it starts making a crackling noise. I have to turn my speakers up all the way to the maximum (normally this would blow them up). The windows volume slider is on maximum so that isn't the issue.
When I plug my speakers in the front of the case everything is working as normal, it's only when I plug them into the back of the motherboard.
I've updated the drivers and even unplugged all my USB devices to see if the problem went away.
Any advice on what this could be?

MSI Z97-G45 GAMING Sata controller performance

Hello
I have an question about the Intel Z97 Express Chipset Sata 6gb controller on my MSI Z97-G45 GAMING motherboard.
Is there any difference between the sata ports performance that can make different results when testing the hard drives. I have an Seagate 3Tb HDD and an WD RE 3Tb HDD and the Segate seems faster. When testing the drives with the manufacturers test suites Seagate takes about 1min to test and WD takes 2min to test and in HD Tune Pro Segate shows a faster speed and a more even curve.
Could this big difference between the harddrives be affected with which sata port that is being used or are the all the same?
Thanx
Niklas

Im quite sure my sata cables in my new computer says 6gb on it but im not 100 sure. Im using Asus black Sata cables with black/white connector and the Sata cable included with the motherboard. So there should not be any problem.
From reading this test it seems there no difference between 6gb and 3gb cables as long as they are high quality cables from known manufacturers. I only own Asus red 3gb cables in my old computer and black/white Asus 6gb cables and the ones included with the modtherboard in my new computer.

MSI Z97-G45 Gaming MOBO DIMM issue

So, I have what seems to be a rather common issue I've heard as I continue to research more about the issue, and I'm hoping that it's not my board... but chances are it is my board. My (relevant) specs are as follows:
CPU: Intel I5-4690k
Heatsink: Cool Master Evo Hyper 212
GPU: Radeon HD 6970
Memory: 2 x 4GB DDR3-2133mhz G.Skill Ripjaws X
Storage: Samsung 840 EVO 500gb SSD
So, when I first cracked open my new MOBO box and got a look at this beauty a few days ago I was overjoyed, but quickly became dismayed. At first I thought the pins were bent where the processor mounts, but that isn't the issue here. The issue is that whenever I stick my RAM into the third and fourth socket it literally does not boot up. I can turn it on, the fans go, power turns on and lights flash... except there's no picture on my monitor, the light to my keyboard doesn't boot up, and then it restarts itself before turning back on and resuming... again without any sound, picture, or keyboard use. I stick 1 RAM stick into the third or fourth slot, just one and no others, and it won't boot to the bios or OS, but if it's in the first and second slot then it runs no problem. Except for the first time I received a windows error - my screen went blue and pixelated as I was playing Skyrim for a split second before it rebooted. The error it gave was ProblemEventName: BlueScreen LocaleID:1033...
A quick google search will show that it's listed under a ram issue. So, I was hoping that it was ONLY my ram and decided to switch it out for 2 x 4g 2000 kingston ram from another system in my home. First and second slot no problem, yet if it goes into the third or fourth slot then same as before; no boot to BIOS or OS. I can't believe that two sets of RAM are faulty as I have the kingston's dual channeled in another system that has been running quite well for over two years now. I'm hoping anyone else has had this issue and solved it, because I really, REALLY, don't want to RMA my motherboard, but as far as I can tell I received a defective board and am going to need a new one from MSI. Can anyone help me out or just confirm what I think I already know to be true? Thanks in advance for the help!

Yeah... sadly that's my conclusion as well, but I thought to get a second (and third) opinion just in case my own diagnostics were lacking. Part of me wants to just leave the problem, but I know it won't go away. Looks like I'll be RMA'ing my board - here's to hoping it doesn't take longer than two weeks to get another one back! I was really digging the BIOS interface and the better performance, too :( .

Can my MSI Z97 G45 Motherboard fit in an AEROCOOL DS200 case?

Just want to know if it would be possible. if any body knows that would be great. thank you.

that case supports Motherboards: ATX/Micro ATX / Mini ITX
and the motherboard is a ATX form factor so YES it is supported in the case and would fit just fine

Z97-G45 Gaming boot loop issue

Hey everyone,
My new build seems to be giving me problems. I put everything together, imaged my SSD and everything seemed to be working fine at first. I had games running and was getting excellent performance with everything on stock settings. Then I started to sync my Plex media server with all it's contents and my computer froze. The keyboard/mouse were non-responsive so frustratingly I reset the computer manually.
Now my computer fans will boot up and then immediately turn back off.
So far I've:
-Disconnected everything except my CPU/RAM and PSU -- I got the same boot loop response
-Initially, I was able to get the system to the BIOS by changing the configuration of the RAM. Now that no longer works. It would require me to change the RAM multiple times, and the system by random chance would sometimes boot to the BIOS. It would freeze if I tried to get into the OS.
-I just exchanged the PSU with a known working component. (Both 750W)
-I reseated the CPU and ensured I had a proper connection between the heat sink and CPU
There doesn't seem to be any physical degradation of the motherboard.
Here's the specs:
MSI Z97-G45 Gaming Motherboard BIOS v2.0
Intel Core i7-4770k processor
Corsair H70 CPU heat sink
16GB Crucial Ballistix Tactical (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600(I've tried both w/ XMP on and off when I can get the system to boot)
Nvidia Gefore GTX 750 TI Graphics Card (also tried onboard DVI connections)
Corsair HX750W (tried also my Thermaltake 750W)
Zowie Mechanical Keyboard
Zowie optical mouse
Windows 7 Ultimate Edition 64-Bit
1x 250GB Western Digital Black
1x 1TB Western Digital Black
1x 120GB Corsair Force 3 SSD (Broken in my attempts to plug/unplug it and the terminals snapped -- SOOOO frustrated at that. I have the 1TB Western Digital imaged with the same OS now.)
Hopefully you guys have an idea to try before I RMA it...

It's used to clear the CMOS, so no, it should not have a jumper on it. Most use a flat tip screwdriver to short it to clear CMOS, or the clear CMOS button at the I/O plate if one is provided there.

Z97 g45, graphics problem

Hi there.
I'm trying a new build with:
MOBO: MSI z97 g45
CPU: Intel i7-4790
RAM: 16 GB ram (corsair vengeance CL9 1333 MHz) 4x4
edit: additional info:
COOLER: Intel stock cooler
PSU: Corsair VX550W
BIOS: 7821v23
My system continues to crash and instantly reboot after some random time.
At some point I found out that shouldn't I perform any significative task, it would never crash (like letting windows on with only task manager open).
After I load up some programs in windows, it crashes.
I'm 100% sure it is related to Intel graphics HD 4600, because after I increased the amount of dedicated memory (from 64MB to 1024MB), I could perform a lot more tasks before crash. Finally, I tried using a video card and the system worked perfectly.
I have installed all drivers through the CD and I also downloaded the latest intel graphics driver through MSI website (those downloaded directly from intel won't work), but the issue persists..
I'm really confused

Quote from: RemusM on 09-September-14, 21:29:25
First of all, that's NOT your video memory.
That's the reserved system memory for GPU tasks.
128-256 MB is more than enough in most of the cases.
Secondly, you cannot increase the amount of dedicated video memory.
For your CPU (embedded HD 4600) that limit is 1.7GB and is controlled by the GPU at runtime (depending on the graphics demand).
So I guess I was just changing the upper limit of the memory, otherwise, what's the exact use of that option in bios ("Integrated graphics reserved memory")?
Anyways, for the graphics card I'm thinking about a gtx 770 or 780.
I checked power calculators online and they all say the system will consume under 450W, my choice is between Corsair CX500M or CX600M, since they are both quite less expensive than 750 and should be enough.
So.. are these two's 8 pin power supply compatible with the cpu?
edit: Wait, I just saw your link. That RM sounds good, I'll check it out.
