MSI X99 AC Power Motherboard 8pin+4pin CPU Power?

Hello, I just opened my msi x99 ac and I see it has an 8pin and 4pin cpu power near the top, now that is like what my asus extreme 1150 had, however I only have 2 8pins from my 1200w corsair ax. However right next to the 4pin is a little something, so the 8pin wont work because there is no place for the extra 4pins to hang down. How did you guys wire this up? Because before I just use 2 8pins and the 4 extra pins hanged down the side, but it wont work with this mobo
Thanks

As far as I can guess, 4 pin is for OC. How do you connect it? I don't know. But I think it will work fine without this 4 pin.
Check the manual

Msi x99 ac power do you have to enable last pci slot ?

on the msi x99 ac power do you have to enable the last slot? do you have to do something special to get it working ? all the pci lane switches are on

Quote from: badboy2k on 24-September-14, 09:26:05
all 3 cannot be x16 as there are only 40 lanes there one is a x8!
if you have 4 cards it should split them on the x16 slots to x8,x8,x0,x16,x8! if your lower slot is not doing x 8 either you have a bad PCI-E slot or a bent pin in the socket!
Its not finding the 4th card at all, and it was before, and havent moved it around since. Would a bent pin come and go like that? How do i fix it?

MSI X99 SLI Plus - Blue Screen at Log In

After my $2000 computer died, I rebuilt using a new MSI x99 SLI plus motherboard, 5820k cpu, and ddr4 2600 for $1100.
It has been 18 days.
I was questioning the motherboard since the beginning since USB devices seemed to go in and out as if they were being plugged in in the middle of working, but I got around most of the problems by not allowing the PC to go into sleep mode.
This morning I wake up and go to check my email and the computer does a wake-up that is different. The bios screen comes up and then I see "resuming windows..." It gets to the log in screen and I enter my credentials. A few seconds later blue screen and reboot.
I try safe mode - log in, blue screen, reboot
I try system restore to a week ago - log in, blue screen, reboot
The store is not going to take any components back, they have a 15 day return policy and it has been 18 days. Nice!
I am not sure whether or not I can really say it is the motherboard. Maybe it is the GPU, who knows?
Anyone know of a way that I can get the details of that blue screen when I cannot even log into safe mode to look?
What kind of troubleshooting would you try?
I am ready to swallow a shotgun.

Quote from: badboy2k on 08-November-14, 06:39:33
a roll back may have fixed it but it just depends when it was last updated! - i mean when was the last time that image you where trying to roll back to last updated was it before your problem started?
Everything was working as of 4:00am Central Time Today (11/7/12).
Blue Screens after log in started as of 9:30am Central Time Today.
There has been no windows update between 4:00am and 9:30am today that I am aware of.
The rollback to restore point was to 11/4/14, which would go well beyond any update if one did occur, which it couldn't without my clicking the install updates button manually.
There was no new hardware installed and no new driver updates done between yesterday and today. I played a few games and went to bed :p
Quote from: badboy2k on 08-November-14, 06:39:33
a blue screen when windows trys to start is usually it running the drive in the wrong mode: enter your BIOS - go to settings - advanced - integrated Perifirals - SATA mode (see if that is in AHCI mode)
I'll double check the BIOS in a bit when I get home from work, but again, I don't see how the BIOS setting would change all by themselves, unless there was a power outage or surge. Neither of those occurred.
I think all signs are pointing to hardware failure. Either the motherboard, GPU, or RAM.
I'll do a memory test and if that doesn't shed light, a reinstall of Windows, if that doesn't fix it, I'm RMAing.

MSI X99S SLI Plus: Ethernet network disconnecting

I have an MSI X99S SLI Plus motherboard, and it works great except that my wired ethernet connection using the built in Intel adapter randomly disconnects. This is on Windows 8.1 x64.
I have downloaded the latest drivers from Intel for the I218-V adapter (which are newer than those on the MSI site), have tried four different ethernet cables, and have disabled all power saving options in the adapter properties. None of this works. I'm about to give up and either RMA the motherboard or buy a PCIe ethernet adapter, but I'd love to see if anyone has advice.
Here's the disconnect events in the event viewer:
Here's my driver version:
Thanks for your help!

Yep, I tried rolling back the driver, as well as lots of other things:
* Updating router firmware
* Changing from auto negotiation to full duplex 1 Gig
* Changing from auto mode to slave mode
* Trying yet another ethernet cable
* Lots of other suggestions from other forums...
Nothing worked. I am going to RMA the motherboard.

MSI X99S Gaming 7 and debug code 67

Hi,
I have MSI X99S Gaming 7 motherboard, Crucial 2x8GB 2133 DDR4, MSI GTX970 Gaming 4G, Corsair RM650, i7-5820k setup.
When I am trying to boot the machine it always stops and the debug led shows code 67. I have tried to take everything out, reseated processor and to boot with just the minimum set of components. Result is always the same code 67.
I am running out of ideas. Do you have any hints or should I just return the mobo and processor?
Best Regards,
juha

So are you going to RMA the board or just use it with 2 sticks? Thats means you are not planning on using it in quad channel, would be a waste.
Anyways if I were you I would definatly RMA it asap. This error 67 problem people are having seems to be widespread. MSI really need to look into this.
As has been said previously, contact MSI. Should they look into it? Yes, but the moderators here are not MSI employees, and while we can bring issues to their attention, we cannot make them look into problems.
So if you have this problem, please contact MSI directly: >>How to contact MSI.<<

How to update my MSI X99S Gaming 7 Bios without loose my raid settings

Hi all,
I've got a MSI X99S Gaming 7 Motherboard.
Last time I used MSI Live Update and I performed BIOS update I lost totally my raid settings ( O.S. HardDisk C is build on my raid 1) and I had to reinstall all from 0. Now MSI Live Update notified me a new BIOS version available, is there a way to perform it without lost my C Drive one more time?
Thanks in advance for your help.

Quote from: JLio01 on 03-March-15, 09:17:09
The only settings should do is after BIOS updating, go the BIOS Settings--Advanced--Integrated Peripherals--SATA Mode switch to [RAID Mode], and everything should be fine.
Yes exactly, that's usually and typically which has to be done.
But with some note there are an exceptions from this:
in the past there was some BIOSes due bugs which caused RAID array lost issue after flashing,
assume raid was re-enabled after the update,
but RAID array was lost(didn't recognize the settings) and didn't show and unable to rebuild..
so its always good to have a backup of important data just in case..
don't trust too much to technology

No USB power from MSI X99S Plus and no Vision from GPU.

Dear Forum,
I have build a new PC with a MSI x99S plus motherboard but when I start it up the fans start turning but I get no vision and even weirder there is no power coming out of the usb ports. I have checked every connection, I disconnected everything that was not nessesary and even tried to start up without harddrives connected. Still only the fans start turning and some leds light up but no vision and still no power to the USB ports
I have used the following components:
MSI x99S plus motherboard
MSI 3G gaming GTX 780 GPU
Seasonic G650 PSU (650 watt)
Corsair Venguance LPX DDR4 4GBx4 ram
Corsair H105 Hydro Series CPU cooler
Intel I7-5820K CPU
128 GB samsung SSD (for booting)
2 TB WD Hard drive
WD DVD Drive
Ill hope someone regonises the problem.
Also this is the first forum topic I have ever started so if I am doing something wrong please give some tips!

No I had not tried to boot it with one memory stick and well it starts up now! Many Thanks! Do you have any idea what would cause the PC not to boot with 4 ram sticks in them? What I am gonna do now is boot it with one memory stick more at the time too see if one is broken.
Many thanks!!
I am happy now
can be many things:
* defective memory stick
* defective memory slot
* incorrect memory parameters: too high memory freq., too tight timings, too low voltage, too tight command rate to handle 4 large memory stick
* not fully compatible memory sticks with current BIOS version
* could be bent-ed pins(s) on the CPU/mobo

MSI X99 SLI Plus won't power up

Hi, here is what I got:
Motherboard: MSI X99 SLI Plus
Processor: Intel Core i7-5820K
Memory: G.SKILL Ripjaws 4 series 64GB (8 x 8GB) 288-Pin DDR4 SDRAM DDR4 2800
Power Supply: CORSAIR RM Series RM1000 1000W ATX12V v2.31
GPU: ZOTAC ZT-90101-10P GeForce GTX 970 4GB 256-Bit DDR5
The symptom detail is this:
1.If I power on (either through power button on case or MB) for the first time, only the fan that connected to PSU directly will spin for half of second. And then it stop and system is total slient.
2.After that if no matter how many time I push the power button nothing happen.
3.If I clear the CMOS and try power up, then step 1 happen.
4.The only thing that lit-up in MB is the built-in power button
Here is what my system look like
So far I have try to switch out different GPU and switch around the RAM stick but still does nothing. Any suggest will be very helpful tome. Thank you.

Take it all out the case and inspect the board for any visual defects.
Place it on non-conductive surface (wood, cardboard, NOT antistatic bags) and test with one stick of RAM (try different odd numbered slots) and VGA card. Make sure all power connecters are well connected.
Next step, test with another PSU if you have one.
Check CPU socket for bent pins, either with magnifying glass or you can take clear macro photos with good light and inspect them.
Best not to install anything in the case until you made sure it's working, at least the main pats (CPU RAM VGA) and main hard drive, it's nearly no overhead and saves a lot of time when turns out bad.

According to the manual, error code 67 is "Late CPU Initialization"
What is the serial number of your motherboard? What CPU are you using with it?

MSI X99S Gaming 7 Won't Boot

Hi -
I just recently purchased an X99S motherboard. I put it all together, and all was fine for about 24 hours. I updated the BIOS and then started running a defrag and left the machine on while I went to work. When I got home, the machine was off. It's not responding to the power button the board or on my case. If I turn the power off on my PSU and turn it back on and hit the power switch, I get a split second flash of lights and then nothing. I initially thought that it was my power supply so I bought a new one. I got that installed and same thing. One thing to note is that the MSI LED up by the 24 pin connector is on red. I've already tried the secondary BIOS and I have removed all of the memory except the DIMM in Slot 7. I haven't yet tried to remove the board from the case yet and tried it on a non conductive surface. I just wanted to get some thoughts on that debug LED that is currently on. I believe the motherboard has just died, but wanted to run it by someone first.
Here are my specs:
Board: MSI X99S Gaming 7
Bios: Version 14.7
VGA: MSI GTX980 Gaming
PSU: EVGA 1000 Watt G2
CPU: Intel Core i7-5930K 3.5GHz
MEM: Corsair Vengeance 2666 4x4gb CMK16GX4M4A2666C16
HDD: PNY 256GB SSD
COOLER: Corsair CWCH60 Water Cooler
OC: None
OS: Windows 8.1 64bit

Take it out of the case, place on non conductive surface (wooden table, motherboard box) and run it then. Also try with single RAM stick in every RAM slot.
Try clearing CMOS >>Clear CMOS Guide<<
Also make sure all power connectors are properly fitted in.
What way did you update the BIOS? Also was it successful?

New PC on MSI X99S Mpower frezzes

Hi,
My brand new PC assembled on MSI X99S Mpower board is randomly freezing very often. Sometimes 5 minutes after start and sometimes after few hours. Even when CPU is not in stress (only internet browser launched). It's freezing when it's overclocked and on default settings. I've tried to remove one RAM memory and replace to another but it's still freezing. I am really confused because I can't figure it out what is the source of a problem.
My setup:
MSI X99S Mpower
i-7 5820K
Crucial ballistix sport 2x8gb
BeQuiet dark rock pro 3
BeQuiet PURE POWER L8 | 530W CM
boot SSD Kingston 120gb (M.2)
Graphic MSI Geforce GT790
Windows 8.1 64bit
Bios M.6

Quote from: JLio01 on 22-May-15, 09:09:35
What's your graphic card? I googled it but didn't get GT790? And what graphic driver you use?
Sorry my mistake it's MSI Nvidia GT730
Quote from: darkhawk on 22-May-15, 05:12:45
Do you have a different video card to see if that really is the problem?
Unfortunatelly I don't have ony other graphic but will ask today some guys at work
