MSI Z87 GD-65 Issues

Hello,
Can someone please tell me if there's a compatibility issue with my components or what can cause the issues that i get from time to time (not allways). I've recently upgraded my system, actually i rebuilt it from scratch about 4 months ago and a few days after i put it together start noticing some "issues" like BOSD, many system freezes, my ram wasn't allways fully displayed (4gb out of 8) usually a restart would fix this one,when rebooting system sometimes i get D5 in the right corner of the screen and on mobo and just stops right there (this was also got fixed with 1 restart. At this point i'm assuming that either my mobo or my ram sticks. Any advice? These are my computer specs:
Board: MSI Z87 GD-65
Bios: V 1.6
VGA: EVGA GeForce GTX 780 SC w/ EVGA ACX Cooler 967 Mhz
PSU: Corsair CX750 80 Plus Bronze
CPU: Intel Core I7-4770K
MEM: Vengeance Pro 8GB (2x4GB) DDR3 DRAM 2133 MHz C11
HDD: Western Digital Black 2TB SATA3 7200RPM 64MB WD2003FZEX
COOLER: Corsair H100i
OC Genie: 4.00 Ghz (i've never overclocked my pc besides OC Genie)
Ram: 2133Mhz 1.5v
OS: Microsoft Windows 7 64 bit
Thank you.

D5 = No Space for Legacy Option ROM that points to some sort of problem with the graphics card! (try it in another computer and see if it makes that do the same)
also your symptoms of sometimes your RAM shows only half could be your RAM is faulty! (try each stick individually)

MSI Z87-G45 reboot issue

I build a gaming system based on a MSI Z87-G45 motherboard. Everyting is working fine with windows 8.1.
I can boot, shutdown, suspend, ... but i can't reboot. When I reboot, from os or from bios, my screens go to black and the fans continue spinning. The computer do not reboot. Never. I have to press the power button for 4s, and the once more in order to manualy reboot.
I'm running the 1.9 bios with stock settings. All my drivers are up-to-date (dowloaded from the product support page). I think that the problem is bios related since I can't reboot properly from it. Oh yes. I've got the A2 code.
I tried different settings like to set the wake options from os and so but it didn't work.
And I've got a RM750 psu and i'm not drawing so much power out of it.
Any ideas?

I had chosen to update the 1.9 bios with M-Flash but I hadn't chosen the bios+me option. Now i've done it and it works. No me driver reinstall needed.

MSI z87-G45 network issue

Howdy.
I've recently started using Powerline networking. Its pretty awesome, but every so often my connection drops. If i look at the powerline plug, all the lights are still on, but when i look at the network port none of the LEDs are on. Sometimes it comes back by itself, most of the time i either need to remove the cable and plug it in from the back of the NIC, or as i have a ssd its quicker to restart the computer. I'm using Killer e2200 Gigabit Ethernet Controller driver version 8.0.2.42 . I also tried the other method mentioned here about using killer cleaner and only installing the drivers but not the application package, but it happened then too.

Have you tried a different lan cable?
well it just happened there. I got it wrong though, the NIC leds were on, and it looked like it was recieving data, but windows said it was connected to an unidentified network. Next time it happens i'll see if i can test it with my partners laptop, and see if its the network, powerline or cable

MSI z87 g45 Boot up issues

So I built a computer for my sister and her husband and it has been having some boot up issues,Here are the computer parts:
wiindows 7 64bit
MSI Z87 G45 Gaming motherboard
INTEL CORE I-7 4770K 3.5GHZ
RADEON HD 5700 GPU
G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1866
kINGSTON 64 GB SSD ( spare part, not sure the numbers)
Sunbeam PSU-H680-REV-US 680W ATX 12V 2.0 Power Supply - OEM
Seagate Barracuda ST2000DM001 2TB 7200 RPM
ASUS Black 12X BD-ROM 16X DVD-ROM 48X CD-ROM SATA Internal Blu-ray Drive Model BC-12B1ST/BLK/B/AS
I've cleared both the HDD and SSD and now I'm looking to check the msi z87 g45 mobo, The computer starts up and sits on a2 for a while and then sometimes it fails to detect the SSD and says a0 and then I have to go back into the bios after I reset the computer again and maybe it detected the SSD and I can set it to boot from that again because it constantly changes the boot order, and sometimes it gives a blue screen when nearly into windows and then restarts, I had transferred some data from their old computer to this one and the data had virus's in it and I didnt know so I eventually found out and a day later and got rid of them all and the computer started behaving better but not fixed, faster mainly, I don't know if the virus may have altered some files so, I have a few more things to try, any help would be appreciated.
(Something I forgot to mention is that when I unplugg the HDD all the issues go away, the computer seems to work fine, But there are no issues with the hdd, ive tested it with seatools and I plugged it into my computer and restarted mant times as well as used my computer for a while and nothing, the HDD is fine, the start up on their computer sits on a2 for a long time when it isnt going to work and it only happens with the 2tb seagate HDD plugged in)

which storage drive holds the boot files the SSD or the HDD? the ATA mode of the BIOS needs to remain in the same mode it was when Windows was deployed to the storage drive. next the only way a BIOS settings will change with out user input is if the Li cell battery is going dead/the BIOS is getting reset frequently. sounds like you're about at square one, I'd format the Seagate 2TB HDD, install windows onto that either in RAID or AHCI mode whichever your preference, you can use the 64GB SSD as caching later if you use RAID mode, if AHCI the 64GB could be spare. I don't understand the SSD as boot drive method, it doesn't make sense the solid state storage is volatile meaning it degrades over time, the HDD isn't and the performance gain isn't going to change the way you use your PC. AHCI has it's advantages it's up to you. Following those steps is the only way you're going to keep the computer booting on a regular basis. You shouldn't need to manually configure which storage drive to initialize/boot from first, the BIOS automatically goes through your devices to find boot files then boots from the first one with boot files, it won't even try to boot from a device without boot files, because it can't. Just to reiterate the BSOD you speak of sounds similar to the ATA mode changing to something other than what it was when Windows was deployed to the device.

MSI Z87 Mpower MAX Internet Issue

Hello guys!
About a week ago Ive got the MSI z87 Mpower MAX for my new build.
However, I had some stranges issues with my internet rooter. He restart almost every hour, aleatory!!!!! Only with this pc (I have another one and it works fine)
So, I changed the rooter for a brand new one, and the same problem persist, only with the mpower max... Its not always, but 7-10 times in day my rooter restart if its plugged on my mobo.
Idk where start to solve this...
Im using the Windows 8 Pro version, with Avira Internet Security.
Can anyone help me? :(

I deleted your double post. Don't try again with multiple topics on your issue: >>Please read and comply with the Forum Rules.<<
Also it is obviously impossible to help you with just the board model and the info that you have an "issue"... Add full specs and proper description of the issue: Follow >>Posting Guide<<

New MSI Z87 G45 Build Stuttering Issues

So few days ago i finally built my new rig:
Specs:
Intel 4670K
MSI Z87 G45
MSI 760 GAMING OC
G.Skill Ripjaws X 8GB 1600 CL9
Seasonic G 550
Samsung Evo 250
WD RED 2TB
So i noticed that i get micro stutter when playing HD videos or youtube videos. Same stutter applies on some HTML5 effects and desktop also..
There is no stutter present when gaming but i do get kind of "slowmo" feel even when my FPS is high enough 60+ (or i'm just picky or somethin...)
I tried everything from installing drivers,, reinstalling OS, Using HDD as OS drive then used Oboard GPU and still the same issue.
Does anyone know what could be the problem? could mobo be damaged? memory? or cpu?
I even did tons of benchmarks and everythine is stable and fine and shows no ERRORS.
I also updated the bios to the latest version (1.5)
Does anyone have any clue what might be going on?
I think few monhts i found someone who had similar problem and fixed this but cant find it anymore...

Are you able to post screen shots of the memory and spd tabs of CPUZ?
Is the ram installed into DIMMS 2 & 4? (2nd and furthest from the CPU)
Have you tried a full Cmos Clear? >>Clear CMOS Guide<<

MSI Z87 GD 65 bios issue

I have a 4770k and an msi z87 gd 65 motherboard which came with the latest bios version.Today, I tried overclocking my 4770k with bios A (the one with blue led), hit F6 , the pc restarted but there was no display on the screen, the fan on the cpu, gpu and the case fans were spinning and the debug led showed the code A2.Tried restarting the pc a few times, still no display, only the code A2 written on the bottom right of the screen.I flipped the multi_bios switch to bios B (the green led one) and started my pc.My pc booted into windows 8 without any issues.How do I recover my bios A, as I want to try all the tweaking and tuning in that bios and keep the bios B at default settings(thank God for the dual bios that my pc started).Any help would be much appreciated.

MSi z87-gd65 OC Genie and RAM frequency issues

Hey all,
I just built a new computer (my first build), and am quite glad with the capabilities of the machine. However, whenever I try to turn on OC Genie or bump up my ram speed to 2400 MHz(I believe this is the native speed, but the motherboard puts it down to 1333MHz) the system fails to boot, and sometimes hangs in a rebooting cycle. Eventually, the motherboard gives an error on the screen saying that the changes made have failed and was restored to default settings, and to press f1 or f2.
I admit I am a complete novice at overclocking, and probably do not know what I did wrong. I've updated the bios, cleared cmos, and tried both bios A and B, but have got the same results. I was hoping I could get some help on this forum and learn new workarounds! Any help is greatly appreciated.
My Build:
i7-4770k @ stock frequency

Hey man, thanks for replying. The first thing I tried, before overclocking, was to enable XMP from the UFEI. When i enabled it, the board would show that memory was OC'd to 2400MHz and bumped up to 1.65 voltage. This is all shown prior to rebooting. When I would reboot the computer however, the system would fail to boot and I would get the same error saying all "overclocking failed, reset to default settings". I believe that my ram is the cause for my inability to overclock. I found out that motherboard is not compatible with it at extreme speeds. The max speed I can get out of my ram is 2133MHz with no problem whatsoever in rebooting. This is without changing the voltage of the ram( keeping it at 1.5v) . If I change the ram voltage, I'm pretty sure it would fail to boot.
Yeah good luck with OCing and please let me know if you find anything useful. I'm afraid that this forum does not have much to offer, so you may want to try some other forums.
Jms and Xfx are right. By default mine booted to at 1600mhz. I enabled XMP and it brought it to the rated speed of 2133mhz. I'm not trying to overclock my ram further than the rated speed. Pointless to me, considering I'm coming from a rig that had ddr2 with 800mhz. As you can see in my pic, the one with blue LEDs is the 7.5 year old build. Still going strong. Anyhow, if you do overclock, make sure you disable the XMP. That way you can eliminate another possible instability issue. I'm a member of a few forums, and I was suprised to see these forums not respond very well. For the guys who did respond, I thank you! You may also want to check out overclock.net There's are plenty of people there and "clubs" you can be a part of. I'm finding a lot of useful information there. Most people won't get mad about noob questions unless you do like me and ask the same ones in multiple threads lol! Hop on over there and check it out. My name there is Scotty Mac.

MSI Z87 G41 PC MATE GRAPHICS CARD ISSUE

Hey gus,
Yesterday I put together a new build, however I can only get integrated video to output to the monitor and not my discrete GPU. I have updated the bios to 1.4 from 1.2, made sure the GPU in question works (by trying on another machine) tried different cables etc etc. When I go into the BIOS I see there are two options for PEG and IGD modes. Default is PEG which is what it should be set to I would think. If anyone knows a fix for this issue please help! Thanks!
MOBO: MSI Z87 G41 PC MATE
PSU: THERMALTAKE 600 WATT
CPU; i5-4670K
GPU: GTX 560

>>Use the MSI HQ Forum USB flasher<<
Use option 1 pointed directly at the attached archive or run the bat file from pure dos.
This is bios 1.4
Make sure this is your board prior to flash: http://www.msi.com/product/mb/Z87-G41-PC-Mate.html#/?div=Driver&os=Win8.1 64
You will need to re-install the ME drivers after the flash.

MSI Z87 GD65 Gaming and msata speed issue...

Hi,
So I'm running the MSI Z87 GD65 Gaming with a 128GB SanDisk msata. Now it all works perfectly; no BSOD or crashes, but what I have noticed is that sometimes when the PC boots and I look in Intel Rapid Storage Technology, the msata on port 5 is running at 3Gb/s not 6Gb/s: I verified the speed loss using AS SSD benchmark. Reboot and it's back to 6Gb/s and back to full speed.
Anyone else seen this or have an idea of a solution?
Thanks

Quote from: JLio01 on 06-March-15, 14:21:58
How often can you notice the problem? You mentioned AS SSD Benchmark has speed loss, what's the result of speed test then?
I notice it a couple of times a day minimum

MSI z87 G43 OC GENIE ISSUE/Bios UPDATE

Hi Everyone, This is my First time posting to the forums.
Here Are my System Specs Before I post the question
Motherboard: msi z87 g43
CPU: intel core i7 4770k (haswell)
RAM: Corsair Vengeance Ram ddr3 clocked at 1333mhz, 16gb, using 4 4gb sticks.
GPU: evga gtx 770 nvidia
PSU: Bronze certified psu at around 850 watt.
CPU COOLER: is a standard corsair single radiator water cooler
QUESTION/PROBLEM:
Ive had this computer built for about a year (basically right when the gtx 770 released). I have no problems with the device and it works perfectly. The motherboard however is where my problems starts to arise. I tried my hand at overclocking but ended up with a blue screen after some stress testing and just set my values back to default. But since then I really havent tried anything new with it. However, I noticed OC genie and I thought hey maybe Ill try this out for a chance. So I boot up and go into the bios set up (all values are default) and press the oc genie.As soon as the screen flashed back up I get a black screen and can not post. The only way to actaully fix this is to reset my CMOS which luckily I know how to do. But the black screen displayed also had a number letter combo at the bottom. It displayed 9C at the bottom in white. But when I get a successfull boot into the bios right beofre the bios logo I get a black screen with A2. But the A2 appears in every boot. Now heres where things get funky. I have a logitech Camera I use primarily for skype. When I have the device plugged in before the computer is booted. When I try to boot I get the black screen with the 9C, but when I unplug and reboot, I get the A2 and I get into my OS.
Now I tried overclocking again at 46 multiplyer with a 1.2v but When I did I get text saying its not successfull and resets my bios info, (which is cool considering oc genie didnt do this it just corrupts my CMOS).
So you must all be asking what version of the bios I have and the answer is 1.0....
Now I know there is a 1.9 and even a 1.A version which came out this year in 2014
The problem with this however is I know the dangers of flashing my bios and it can really screw up my mobo as in brick the darn thing. But from what I read, Live update form msi does not work and I shouldnt use it. But Is flashing the bios via the bios set up where there is a section specifically for flashing safe to do? With the oc genie not working im scared to try flashing my bios via the bios setup if that makes any sense
To wrap it up, is it a problem with my mobo, do I need to update my bios to fix it? If yes then what is the safest way of doing it since ive never done a bios update before (but i get the concept put the up date on a FAT 32 load it from it in the bios set up option let it do its thing and boom ) .

The method above does NOT apply to your board. Either use MFlash (bios + ME option) or use the below:
>>Use the MSI HQ Forum USB flasher<<
A.) Download the attached archive (E7816IMS_1A0.rar.rar) and place it on your desktop. Do not decompress.
B.) Download and install the Forum flash tool.
C.) Insert your FAT32 formatted usb stick.
D.) Make sure that all win 8 options are disabled. (Fast Boot etc) Also make sure the legacy USB is enabled.
E.) Start the forum flash tool and select option 1. Then point the tool at the compressed archive we downloaded earlier. Then to your USB Flash Drive.
F.) Boot to the USB
G.) Now follow the directions and let the tool flash
H.) After flashing reinstall ME drivers in Windows: http://download.msi.com/dvr_exe/intel_amt90_mb.zip

MSI Z87-G45 Gaming, sound from USB mouse?

Hi!
I have some issue from my new computer, see spec below.
For the information I have a MSI Z87-G45 motherboard.
I have some sound that occurs sometimes (specially during the first 2-5 minutes) when i move the mouse around.
It occurs as well sometimes when I been using the computer for a while, basically random just more frequently at the start-up.
It's hard to know from where the sound occurs, could be PSU but today I read something on another forum about the motherboard I'm using:
- Higher sound quality using USB, thanks to special adapted current power.
So i wounder if this can be the case? Is that the reason why i get this noise from inside the computer?
Is there some way to disabled this "feature" in BIOS?
Greetings

The sound sounds like the old mechanics hdd kinda.
It comes inside the computer, not the speakers.
My feelings is that it can be the PSU as well, just wanted to check this first, since it most often comes when i move my mouse.

Msi Z87-GD65 Booting Failure With eSATA Drives

Hi Folks,
Before I go down the (probably ill-fated) Customer Service path I thought I'd address the forum here on a little problem I'm having with my Z87-GD65.
IN essence, if I have a hard drive connected to my eSATA port the PC won't boot. I'm using an ICYDOCK 4 bay external enclosure (MB561US-4SB if interested). If the drive itself is on but the HD trays are ejected then it boots. If any of the drives are secured then it'll hang at a post-BIOS/pre-Windows screen where all I get is a blinking cursor for about 30 seconds and then it disappears to a plain black screen. If the device is powered off then it boots.
I've checked the BIOS with one of the HDs running and it doesn't appear within my boot list - in fact, except for one selection in the bios allowing me to disable eSATA there really isn't much I can do there.
I've upgraded my BIOS to 1.30 from 1.00 and the process seems to move a bit further - now I get the oh-so-pretty ugly Windows logo and that's all.
When I do actually boot the PC with the ICYDOCK off then I'm able to get into Windows normally, and turn on the ICYDOCK. After a few seconds all 4 hard drives report in and everything's fine.
I've been using this ICYDOCK for about a year and a half, with 2 other motherboards (neither were an MSI) and i7 cores, and neither of them caused me any issues. I remember that neither of those boards had the port multiplier eSATA capability so I had to buy a controller card with that capability. I could probably dig that up and see if the problem remains.
In case you're wondering, if it helps, I built a Msi Z87-GD65/4770 i7 - based PC with 2 internal 2TB Hard Drives, and 16gb RAM. I already mentioned the ICYDOCK. I used LiveUpdate to install all the latest drivers & BIOS before uninstalling it.
I build & repair PCs for a living so I'm pretty familiar with what's going on with the system. I figure that there must be something happening between the BIOS and Windows "handoff" of the ICYDOCK, but I'm damned if I can figure out just what.

More information please. PSU, OS being used, etc..
Live Update is best uninstalled. Flash UEFI/BIOS the safer way;

Z87-G65 power issue with usb(port reset failed)

All,
I'm having an issue with my motherboard and wanted to see if anyone had suggestions. In windows 8.1 if I have my webcam or external hard drive plugged in USB. I get this error the the USB device is not recognized and the port reset failed(code 43). I noticed when I turn on the PC and it's booting the light on the webcam and hard drive flash like it's not drawing enough power to stay on. The boot sticks at 9c on the screen and I have to reset. When windows boots they turn off. Since it's before windows boots I think this is either a MB issue or a power supply issue. I have a corsair 750 watt power supply so plenty of power. Any ideas?

MSI Z87 G45 GAMING erratic BSOD/freeze @ 2300, stable @1600. Can't solve.

Hi All,
I would welcome some advice. I am about 4 months into a new machine build:
* MSI Z87 G45 GAMING motherboard
* i7-4770K Haswell 3.5 GHz & aftermarket heatpipe cooler
* 4 x 4Gb G.Skill SNIPER DDR3-2133 PC3-1700 (F3-17000CL11D-8GBSR)
* GeForce GTX 650 Ti w/ 2 Gb Video RAM
* Samsung 840 Pro 256 Gb SSD
* Thermaltake 700W Toughpower
* Win 7 Pro 64-bit SP1
The system seems to run fine at the default 1600 MHz RAM speed, however if I implement either of the X.M.P. profiles (which kick the memory speed up to the RAM's advertised speed of 2133 MHz), the system will occasionally (every 8 to 48 hours) freeze or BSOD. The BSOD stop codes are inconsistent in number (0x00, 0x41, 0x1E, 0xC4) and driver. When the system freezes, there is no consistent behavior. I am not doing any other overclocking besides using the X.M.P. profile in the memory.
RAM timing on the 2133 X.M.P. profile is: 11-11-11-30.
I have updated the BIOS to 1.5, including the ME, and updated all drivers in the system. All irrelevant hardware and drivers are disabled. Also I have done the following:
* MemTest+ 5.01 for over 30 hours, all 4 sticks in. No errors.
* Intel BurnTest on 'Very High', 10 passes, no errors
* Prime95 for over day with 90 C CPU temps constantly being hit. No errors.
* Unigine Valley Benchmark for 30 minutes; no issues
I increased V_DRAM from 1.60V (from the XMP profile) to 1.65V, and I also added +0.10V offset to increase the CPU I/O ANALOG , CPU I/O DIGITAL and SYSTEM AGENT voltages. Didn't seem to help. All other CPU voltages are default from [auto].
I rolled the memory speed back to the default 1600 MHz, and the system seems stable as a rock.
I don't really need to have the memory run at 2133 MHz, but it irks me that the system is not stable with the rated components, and I'm befuddled why the stress tests seem to pass just fine, then the system will randomly hang with arguably a far less demanding load than the stress tests.
Note that I have not yet:
* reset the CMOS when changing to X.M.P. Perhaps I should?
* reseated the graphics card or CPU. The latter will require R/R of the thermal grease, which I will do if needed, but it's a pain. Since the system is stable at 1600 MHz, I assumed that all basic systems are working as they should.
* Tried to work my way up in memory speed step by stem from 1600 to 2133 to see where things fall apart.
* Tested the video memory
I suspect main system memory, despite the clean bill of health from MemTest, and based on many of the comments to others with similar problems from the veterans on this board. I don't want to push the CPU voltages too much above the default/auto values, for fear of damage and reduced lifetime.
Also, the power supply is a nice unit from an older high-end gaming rig. It is rated at 700W. The PS does probably have over 30,000 hours on it (24/7 use for 3-4 years), however. Strange that it would work at 1600 MHz fine, and with only slightly more power load at 2133. I suppose stranger things have happened.
I've read the suggestions to run only 2 sticks, rather than 4, but I can't justify dropping $140 on new memory (I don't really need the extra speed benefit, it's more curiosity and just not knowing at this point).
Anyway, perhaps more seasoned souls than I can share their thoughts. The system is perfectly usable at 1600, but I'd really like to know where the lockups are stemming from. Troubleshooting is maddening because of the inconsistency in the long times before failure and lack of repeatability to reproduce the issue.
Thanks in advance for your time.
-Paul

Thank you both for the prompt replies. I'm learning a lot.
Turns out I also found this from G.SKILL in going over reviews of the memory modules I have. Another user had a similar configuration as mine and was having similar problems. G.SKILL replied:
Quote
We are sorry to hear you were unable to get two kits working in the same system. It is not guaranteed two kits can operate at the rated specifications since they were not pre-matched, tested, and guaranteed at factory. With multi-channel motherboards, perfectly matching memory is necessary to achieve high frequency. This is why we must offer high capacity 32GB, 64GB kits, otherwise we can just sell one module at a time and have you purchase as many as you need. Unfortunately, memory does not work that way. If you purchase a 16GB kit rated at DDR3-2133, you should have absolutely no issues. For any further questions or concerns, please feel free to contact us directly for assistance.
Thank you
GSKILL SUPPORT
Not knowing any better, I simply purchased two "kits" of 2x4 GB each and installed them. Perhaps worse, if the modules were matched, I may well have mixed them up so the matched modules don't even sit in the same channels 1/3 or 2/4. G.SKILL seems to have a pretty responsive board, so I'll ask them what they suggest.
Also in the end, I really just want a stable machine. This is a basically an office/engineering machine. My initial thinking was that if the system was unstable at 2133 then there is something wrong with it that needs to be fixed. It sounds instead like getting to 2133 is not guaranteed, and is much more of an art than simply throwing the modules in and powering up the system.
I'm perfectly happy at 1600 knowing the system is stable. Indeed realizing now that 2133 requires overclocking, I may well have backed off to 1600 even if everything had worked just fine at 2300, just to trade extra stability for the (small) performance improvement that I would likely never notice anyway.
I'll put together a post for the G.SKILL forums, and if I get anything useful I'll post what I learn here for completeness.
Thanks again for the fast and informative replies. It's much appreciated.
Best,
-Paul
