Z77A-G43 USB troubles.

Hi there,
This week I did a build for one of my clients for wich I used a Z77A-G43 board and I'm having trouble with most of it's USB ports. Planned for the build was an Asus P8Z77 WS board for this workstation, but since my supplier couldn't deliver on time I was forced to pick another, the Z77A-G43 was recommended to me by my supplier and after reading a lot of positive reviews I gained enough faith to just go for it. Unfortunatly, I have ran into trouble with the board... :( Just my luck!
The USB 2.0 ports on the back function fine, but the headers on the mainboard and de 3.0 ports (on the back as well as on the 3.0 header) give me alot of headache.
The problem was noticed first when I tried installing the OS with a USB stick. First the install failed almost imediatly, telling me it couldn't find the medium. I thought it probably had to do that the install of the OS didn't have drivers for the USB 3.0, so I tried the USB 2.0 port on the front of the case (connected to header on the mainboard). This time the PC wouldn't even POST normal, no errors either.... it just hang there. I'm also unable to enter setup with a USB stick in one of the ports connected to a header on the mainboard. If I plug the same stick into the back, the system POSTs fine, can enter setup, and installed the OS this way. All is fine, as long as I don´t connect mass storage media to the USB headers on the mainboard.
When the OS was installed, I could connect a drive to the front headers and Windows will recognise the drive. I´m even able to read from and write to the drive. However, if I leave the drive in and reboot the PC, I have to take out the USB stick to be able to post (same thing if I leave a SD card in the reader by the way). Switching off legacy USB support in the bios lets me POST with storage media connected to the USB header, but if I restart windows with mass storage connected to the headers, it won´t recognise the drive once it´s booted.
This also happens with the card reader that´s connected to one of the headers. If I disconnect the cardreader and plug it back in with windows running, it finds the cardreader and I can acces my SD cards. If I restart the PC, it posts as long as legacy USB support is turned off (with it on it hangs at the POST), but as soon as windows is loaded, the cardreader isn't recognized and it doesn´t see the cards untill pysicaly I reconnect the cardreader. The bluetooth part of the cardreader is recognized just fine though, and also the webcam connected to a front USB port will start just fine on every boot. Just don´t expect a USB memory stick or the cardreader´s mass storage functions to work.
Is this a known bug with the BIOS at the moment? Or is this a case of defective hardware and do I need to RMA the board?
Things I did so far to help it;
Installed latest drivers
Updated the BIOS to version 2.7 (including the Intel ME) at that point I realized the connection between the problems in windows and the post / bios setup problems with the front USB headers and mass storage.
System specs:
Case: Fractal Design Define R3
PSU: BeQuiet Pure Power L7 (530 watt)
Mainboard: MSI Z77A-G43
CPU: Intel i5 3470 Ivy bridge
Cooler: Gelid Tranquillo rev2
RAM: Crucial Ballistix 8GB PC3-12800 (1600 MHz, CAS8, Non-ECC, 2 sticks)
SSD: Samsung 830 128Gb
HDD: WD Caviar blue 1TB (7200rpm)
Optical: Asus DRW-24B5ST DVD ReWriter
Cardreader: Akasa AK-ICR11 all in one cardreader with bluetooth
OS: Windows 7 Professional
Hope someone can shed some light on this...
Thanks in advance,
Michiel
PS:
I'm sorry for my bad English, it's not my native language and am not used to having to write in it.

I'm not keen on trying to flash beta versions of a bios onto the board, if I'd brick it it would be my own risk. I can compensate for power outages by putting the system behind a UPS, wich I always do, but I can´t compensate for bugs present in a prerelease. It´s just a risk I´m not willing to take, especialy if the problem isn´t one that more boards of the same type have.
If it's not a known issue I think I'll RMA the board... I mean, if other boards of the same type are not bothered by it, by all means, they (my supplier) can send me another one that´s not plagued with these gremlins.
Mainboard has been run on a testbed outside of the case already with one DDR3 2GB stick (Kingston valueram), same result. I will check the CPU pins, but to be honest, I would be VERRY surprised if one of the pins would be off.
Thanks for your help so far, but I think this will be one for my supplier to take back. Hope I have more luck with the board they send back. Is the Z77A-G43 generaly a reliable board? Or would it be wise to request another board? I can't afford to having to tell my customer that the board I got back also failed... It will already miss it's deadline because of this, so I realy need to have a solution asap

Hello i got a problem where my usb plug always stopped working for no reason
when i boot my PC , everything is fine and about 15-30 (sometimes more than 1 hour)
everything is stopped (Mouse , Keyboard , USB Microphone) BUT the Monitor and the Speaker works fine and it is still working
this is really annoying for me when i playing a game and my mouse got stuck and i have to restart my PC
and also i have an electricity problem in my house the voltage is unstable so i have to use stabilizer
is my motherboard affected by the electricity or what? idk i'm really really new at thing like this and do i need to change my PSU / Stabilizer
Thank you

Could you provide more details about the PSU? Wattage rating and the amp rating on the +12V rail(s). Also, what is the current BIOS version? Why 6GB RAM? Are you using 3 sticks? If so, that is known to be counterproductive and has shown performance hits in that configuration in benchtests. Use just 2 RAM sticks in dual channel placed in the proper DIMM slots.
PSU : 600W , +12v1 , 10.35A (Pic below if you want to see it clearly)
BIOS : American Megatrends Inc. V2.12, 11/1/2013
why 6GB? back then i could only buy 6gb because i don't have enough money lol
and i really really need it because it was urgent and i dont use 3 sticks only 2 sticks

Z77A-G43 USB problem

I am new owner of Z77A-G43, cooperating with i5-3570K, 2x4 GB Kingston, just internal GPU in procesor. I have small problem with USB connectors in back of the mainboard. If i connect 1 USB device to USB2 port, i can switch the PC on without any problems. If i connect 3 USB2 devices (webcam, Wireless Keyboard+Mouse senzor, TV Tuner), then if i switch PC on, nothing happend. The PC just dos not start up. I have to disconnect 2 USB devoices, i can keep connected 1 device at max. Or i can connect rest of 2 devices to USB3 ports on mainboard. Then i can switch the PC on with all of 3 USB devices connected. I do not understand this problem. I can live with it, 2 devices in USB3 + 1 device in USB2, but it looks really strange. Should i claim it or?

try to change USB compatible mode in BIOS
don't forget to test speed after that

Z77A-G43 USB port issue

Hello,
I have had this board for a little over a year now and a few months ago the USB ports randomly stopped working. My screensaver would come on and I can't shut down my computer by means of keyboard or mouse and I need to use the power button. What is wrong with it?
Thanks

Z77A-G43 - DRAM banks 1&2 acting up.

Hey, guys. Thanks in advance for your time. I know it gets busy around here.
I am putting together a new system for the wife, and have an odd little issue. The DRAM banks 1 & 2 cause a pre-POST boot-loop when either are used. Banks 3&4 work perfectly. When a stick is in bank 1 or 2, the computer will power on, the fans spin, no video output, then it shuts itself down (regardless of what banks 3 & 4 hold). Repeats a few seconds later. All the usual trouble shooting has gone down. BIOS is all out-of-box default. All the components are brand new, but regardless were systematically replaced/removed one by one to narrow it down to these 2 ram banks. Needless to say, the RAM is fine - tested in two different computers. The memory banks are clean, new, with no visible dirt or damage. It's just odd.
Code: [Select]
1 2 3 4 <- Bank # ... X = used ... O = empty
X X X X = FAIL
X O O O = FAIL
O X O O = FAIL
X X O O = FAIL
O O X X = OK
O O X O = OK
O O O X = OK
The RAM in use is Kingston HyperX DDR3 1600MHz PC3 12800 4 GB (4 identical sticks = 16gb total) (KHX1600C9D3K2/8GX ). With RAM in memory banks 3 & 4, BIOS tones it down to 1333 from 1600, but that's the least of my worries. BIOS shows the timing as 9/9/9/24 and the voltage around 1.45 (can't remember exactly) even when it's increased to 1.65 (as suggested by the sticky). I also tried going 1 stick at a time but it started acting up as soon as I put anything in bank 3 or 4. There's just a lot of BIOS options that I simply don't know what they do.
I realize you guys have seen a lot of issues and was curious if you wouldn't mind lending a hand? I know my way around a computer, but certainly don't have the specialty knowledge particular to these pieces of hardware that you guys do. Any help is very appreciated. Please let me know if there's any information I can provide. I am dumping anything I think could be remotely relevant in this message. I really hope it's not a faulty board. Between disassembly and shipping, that would be an awful hassle.
Here's what I'm working with:
MSI Z77A-G43 (BIOS v2.2B2)
Kingston HyperX DDR3 1600MHz PC3 12800 4 GB (4 identical sticks = 16gb total) (KHX1600C9D3K2/8GX )
Intel Core i5-2500 3.3ghz
Nvidia GeForce GTX 550 Ti 2gb
PSU: Cooler Master GX 750W (RS750-ACAAE3-US)
A-Data 120 GB SATAIII Sandforce SSD (AS510S3-120GM-C)
Western Digital Caviar Green 2 TB HD (WD20EARX)
Case: Cooler Master HAF 922 (RC-922M-KKN1-GP)
No OS has been installed. I didn't want to get too involved until I knew the hardware was staying put.
Thank you again for your time.

I think the potential explanations for your problems are only a few. We can, I think, exclude a memory compatibility problem, since the sticks work fine in other slots.
In my oppinion, what we are looking at is one of the following things:
1. A problem with the memory controller (which is inside the processor) = defective CPU
2. A pin-contact problem between the CPU's contact pads and the board's socket pins causing certain memory slots to be improperly connected to the CPU's memory interface
3. A short-circuit problem, blocking the functionality of the memory slots (test the board outside the case on a non-conducting surface)
4. Defective memory slots or a problem in the underlying circuits = defective board
At your suggestion, I have made a couple of attempts to reseat the CPU (regarding #2). I realize that was a long shot, and not surprised to see no difference. I just wish I had another LGA 1155 CPU to swap out and test #1. I'm going to continue to brainstorm this for a few days before putting in a RMA request.

Z77A-G43 "B4" error code - Logitech G500 Mouse

Whenever I boot up or restart, the bios hangs at a "B4" error code. Some research shows that it's a USB error. Whenever I unplug the mouse, it starts fine.
My BIOS version is 2.40
Any help would be appreciated.

Also several release notes in the full release and beta bios of gaming mouse / keyboard compatibility fixes.

MSI Z77A-G43 RAM Problems

Hi everybody,
I have some big problems with my new build:
Intel Celeron G1610
MSI Z77A-G43
2x4gb Corsair Vengeance LD low voltage 1600 mhz 1.35 v dual channel kit
Seasonic 620w PSU
Saphire 7850 2gb GDDRAM5
My system wont work with both ram sticks in. If I only use one of them (it doesn't matter which one) in whatever slot I want, I don't have any problems. However if I use both of them I get bsods or restarts very soon after windows finishes loading. I must also mention that it's almost impossible to install Windows with both Ram sticks in. I almost always get a bsod when the installer is expanding the windows files.
I must also mention that by default, my motherboard sets my ram to 1333 MHz and 1.5v even if the producer says that the ram should run at 1600 MHz and 1.35 v. If I set them to these values myself in the oc menu, they are reset to the default values again immediately after I get another crash.
I have the latest bios and drivers and I don't know what else to try: ( any ideas?
Thank you!

Hi flobelix and thank you very much for your response. I tried your solution and on the next powerup, my pc didn't crash at all and I ran a couple of games and memory intensive programs.
However, unfortunatelly, after I closed the PC for a while and restarted it again, the problems came back. The ram timings don't change anymore in BIOS but the system constantly restarts. I ran memtest for 6 hours last night with both sticks of ram in and it did not find any errors so I can't figure out what's wrong.

Since I'm desperate, I'm just gonna go ahead and reinstall windows again. During the last successful pc run (after I took your advice), I ran MSI live update and installed the rest of the utility software. Maybe this did something to my drivers.... I'm really reaching the end of my possibilities :(

Z77A-G43 Issue - Bios not working

Dear Forum,
I have a quite strange issue with my brand new system.
Specs first:
MSi Z77A-G43 BIOS 2.2/2.3, i5 3570K, Win7 Professional 64 bit
G.Skill Value Series 8GB DDR3-1333 Kit
be quiet! Straight Power E9 580 Watt CM
Gigabyte GeForce GTX560 Ti
OCZ Vertex 120GB SSD
Western Digital Caviar Blue 500GB
LG GH24NS70
Problem description:
All parts are brand new. Machine was assembled (antistatic wristband used), Display connected to PCIE-Nvidia gfx card.
Display showed post codes (99, A2) in low resolution and got stuck with a blinking cursor in the top left corner.
After some cable checking I switched to the built-in gfx (from CPU) and the machine booted into bios (v.2.2) after showing the MSI logo.
Whenever I tried to change or even view the bios settings, the machine froze and had to be hard reset.
I installed Win7 without a flaw and updated the bios to 2.3 using Live Update. No errors.
Now whenever I trie to access the bios (hitting DEL) the bios image (blueish) pops up for a short moment and the machine reboots. Nothing else I can do there. It still booted though into windows.
I did the CMOS-reset which showed the initial "settings have been reset, hit F1 for setup or F2 to continue" message but when hitting F1 it again flashed the bios image for a microsecond and rebooted.
Windows still booted normally, when starting Click Bios II application it showed the loading screen but nothing happened. So I decided to reflash 2.3 Bios.
--> Nothing changed
I then flashed the Bios down to 2.2 using the MSIHQ-Flash utility (awesome tool) which lead to the same effect as before:
I could access the bios but could not change any settings, the machine froze. The click-Bios application started though.
Now I have two questions:
1) What's the matter with the board/bios? I can still return the mainboard to the vendor but would rather like to see this issue fixed
2) Any ideas with the non-running PCIE-graphics card? Could this be related to the mainboard/bios as well? PSU has 580W and all cables were connected properly.
Thanks for any input that might help..

Wouldn't even bother trying anymore with v2.2 since it needs v2.3 to fully support the CPU you have. Recommend to stay with v2.3 since it updates the Management Engine. Going to v2.2 may be causing a chip corruption of some kind.
Not sure what kind or brand of keyboard is involved here, but try with a generic USB one. I had to enable F-Lock on my keyboard to make it go to the UEFI/BIOS using the Delete key. Test with one RAM stick only in the primary dimm slot. Depending on the manual revision, that is either DIMM1 or DIMM2. Update to v2.3, remove the PSU power cord, remove the battery for awhile, clear CMOS and reset, and test again.
I did use another keyboard, I did a CMOS reset, I have only one module in DIMM2 as stated in the manual. I guess I went through all usual troubleshouting steps. some things in my system don't like each others.
what I did not do so far is comparing the serial of the old and new mainboard. will do that tonight - I srsly hope they didn't send the faulty one again..

Z77A-G43 No Signal Output is this right?

Hi All
I have a problem with a Z77A-G43 motherboard it has BOIS version V1 only and i need to update to version 2.3 to support my i5 Ivy bridge set CPU a have a few questions.
Q1. My question is this with my Ivy CPU installed should the motherboard turn on and allow me to access the BOIS so I can flash by USB/CD? or will the motherboard not allow me to enter the BOIS.
Q2. With no signal output will burning the BOIS file and flashing tool to a CD and booting the system will this auto flash the BOIS when i turn on the motherboard?
Q3. Is there a list of Supported CPU's for the Version v1 BOIS for this board so I can install an older CPU that is supported so i can flash the BOIS?
Hope someone can help here Thx.

Z77a-G43 dual channeling problem

Hello, I know some other people also had similar issues, but I couldn't find a solution.
I was trying to see if the components were working before installing everything in the case, and I have a problem with my mobo Z77a-G43.
If I plug my two piece ram(G.Skill Ripjaws 2x4gb DDR3 2133) into slots 1-3 or 2-4, the mobo does not POST and enters to an infinite reboot process.
However if I plug just one ram into slot 2, everything works great. I checked each piece of my ram, and they work alone in slot 2. So I guess the ram is fine. Also if I plug just one ram to slot 4, it doesn't work. I hope this problem can be solved with some tweaking of bios.
I also checked the pins under my cpu and they look fine.
Thank you for your help.

There have been allot of "memory compatibility improvements" in the bios releases. If your computer is perfectly stable with a single stick.
>>Use the MSI HQ Forum USB flasher<<
Flash to the attached bios using option 1 and point at the entire compressed archive then to your flash drive.
Make sure this is your board:http://www.msi.com/product/mb/Z77A-G43.html#/?div=BIOS
The attached archive will flash your bios to version 2.7 and the ME8.1 1318 firmware extension.
I would suggest running memtest first (included with the tool) if any errors or stability issues, do not flash and proceed to try other memory.

Z77A-G43 Bios Update for Windows 8

Hi,
I am building a pc with the Z77A-G43 and will be running windows 8. Will i be required to update the bios and should i do this before installing the operating system or after?
Thanks

Update the bios first.
Then format the Drive using diskpart to GPT, finally install from USB in UEFI mode.
You can use the forum flash tool for all of this:

If you hit Shift +f5 at the selection screen to enter dos then proceed with formatting the ssd or hdd to GPT.

Z77a-g43 and power save mode

All parts are new.
ASUS gf gtx 560 ti dcII top, corsair 8 gb memory, intel core i5-3570K, 3,4GHZ soc 1155, corsair 600w, msi Z77A-G43 Intel Z77 1155 ATX
Everything was running just fine for one hour. Loaded windows 7 /64 and some servicepack. Then suddenly I got the "power save mode". I´ve tried a different graphic-card with the same result. Took out the bios battery but that didnt hlp. Then tried another corsair 600w but no... The comp. starts, but with a black screen. No usb is working. Tried the blue vga on the motherboard but still a black screen. No beep.
So, what to do? Buy a nother mb?

Here are some other ideas:
1.) repeat the process with a single stick of ram try each stick / try different dimms to see 1 stick is fault or a dimm is faulty.
2.) Remove and re-seat the cpu, while the cpu is out, check the pins for damage.
3.) Remove the mobo from the case and check for foreign objects shorting it out, while it is out, build the computer on a non-conductive surface with 1 stick of ram, cpu, cooler and psu and test.
Pay careful attention to extra stand offs under the motherboard.

Z77A-G43 MS-7758 not able to WoL

So i have been trying all day to get my Z77A-G43 MS-7758 motherboard to Wake on LAN. I have followed every single step there is to follow and i even get the Magic Packet fine when using the WakeOnLan monitor.
However here is where the problems start to occur. As soon as i turn off my computer it does not work. These are the settings in the BIOS:
Wake on LAN is set to: BIOS
Wake by PCI and PCI-Express: Enabled
Wake by USB: Enabled
EuP 2013: Disabled
I have tried fiddling around with the network card settings in windows as well. But i am actually not really sure if these settings can actually affect the Network card when the computer is not in windows. Also when i try to disable of the setting called: Allow the computer to turn off this device to save power in the network card properties, it just enables itself as soon as i click OK.
EDIT: Also the green light on the lan port turns off, not sure if it's supposed to with WoL enabled.
Is there any help to get here? Any suggestions as to what i may try or am i forever doomed?
Sincerely Synit

see https://forum-en.msi.com/faq/article/wake-on-lan
Thanks for the quick response, i did follow that guide and found out that the option: Only allow a magic packet to wake the computer needed to be disabled. And that fixed it temporarily.
However i have ran into a new problem. Each time i start the computer that setting resets back to default and i cannot get it to stay off for some reason. Do you have a solution for this as well?
Thanks again sincerely Synit

Z77A-G43 Memory Timings Messed Up

I'm having trouble with the memory on my computer, and eventually after some searching, I found out that the timings are off (11-11-11-28 instead of 9-9-9-24). I don't know how to change the timings, and I've looked around on the internet for a while and I haven't found anything on manually setting the timings. The XMP is set to 9-9-9-24, but when I enable it and reboot, nothing has changed, and it still fails MemTest86. If someone could tell me how to change them, that would be great. Thanks.
Edit: Sorry, I completely forgot, here are the specs:
Intel i5 3570k @ 3.4 Ghz (no overclock)
Z77A-G43 BIOS v2.4
G Skill Ripjaws X DDR3 1600 Mhz, 8 GB, 2 sticks
Powercolor Radeon HD 7850, 2 GB
OCZ Agility 3, 120 GB, SSD
Windows 7 Home Premium
OCZ ModXStream Pro 700W, 25A

Try with just 1 stick of ram then the other, see if one stick is defective.
If you are able to enter bios, load optimzed defaults first.

and I'm sure there are more than 4 that are compatible?
There are, I usually just stick with Corsair or Mushkin because they have always worked for me.
