4-pin CPU-PWR connector on x99s SLI Plus

I'm attempting to install a Kraken x-61 cooler into my Corsair 780T case and the MSI X99S SLI Plus mobo. One step says:
Connect the 3-pin power cable from the pump to the 4-pin CPU-PWR connector on the motherboard.
In the MSI x99S SLI Plus mobo and the manual (En-6) I can't find anything called CPU-PWR. The 3-pin power cable fits into the 4-pin CPUFAN1 connector, but I don't know if that's the correct connection. Could someone tell me where the CPU-PWR connector is on the MSI X99S SLI Plus motherboard?

it can be confusing to start with but you get used to it once you have done it a few times!
so yes connect it to the fan header for CPU as that line has a sense pin that will detect if your pump fails and will shut the computer off to prevent the CPU overheating to stop it breaking the processor! just take your time and anything your not sure of feel free to ask us!

Build question about the MOBO msi x99s sli Plus

I just started to build a new computer for the first time. I have two questions (at this point, anyway) which I hope someone can answer.
1. When I attached the mobo to my new case (Corsair 760T) with the screws that came with the case, I noticed the middle riser is not like the other preinstalled risers. It's more like a centering post. I watched tutorials that said as much, but what I'd like to know is: Does that center post just stay as is? Because unlike the other 8 risers, there's nothing for a screw to go into for the center post. The mobo seems to be positioned correctly, but I'd like to know if that center post just stays as is.
2. My other question has to do with installing my new Kraken X-61 cooler over the cpu. In several tutorials I've watched, it was stated to remove the back plate on the mobo behind the cpu and replace it with the plastic backplate that comes with the Kraken X61. cooler. But when I look at the backplate behind the cpu on the MSI X99S SLI Plus mobo, there isn't any bolts to remove. I also noticed that the plastic backplate that came with the Kraken X-61 when adjusted to its widest dimensions, lines up with the socket on the top side of the MOBO where the Kraken X-61 heatsink gets connected with thumb screws iinto the socket on the MOBO. Can I use the socket that's already on the MOBO? If no, how do I take off the back plate on the bottom of the MOBO?
Hopefully you will understand what I am asking.

Thanks for responding. I used the wrong term for the backplate in one sentence, calling it a bracket. I meant plastic backplate. But no matter, I got it installed. You gave me a lot of relief, because there is no step-by-step directions with parts from four different manufacturers, so for a first-time builder with practically no technical know-how, it's not easy to know what to do. Once done, I realized how simple it was, though. The bracket on the Kraken x61 was already set and attached to the pump. I just slipped it over the posts I installed for my socket type, and affixed it with the thumb screws.
Thanks again

2nd 8-pin CPU power connector on Big Bang XPower

I am currently using both 8-pin CPU power connectors and am wondering if it is really necessary with my current overclock. For all the BB XPower owners let me know your thoughts on this.

When doing early tests with the BB Xpwr, I only had a single 8 pin CPU connector ( PSU was single +12V Rail). Since it was not necessary but recommended, I purchase an 8 pin Y cord manufactured by Athena. It worked perfectly until I got a newer double cabled 8 pin PSU (Single +12V rail Corsair AX1200). I also supply power to the boards 6 Pin JPWR4. As Jack says, if the PSU has the connectors (or use the Athena), fill 'em up with power!

Random shutdowns X99S SLI Plus, ms-7885

Hello,
I'm trying to narrow down some random shutdowns. These seemed to be completely random and could happen with the computer idling. The computer just shutdowns and reboots. Nothing in the log, no BSOD. I have tried to trigger the problem by running CPU and GPU stresstests without success.
Until wither 3 came out. With witcher 3 the problem is 100% reproducible. Start witcher 3 => shutdown.
I can play other games for hours without any problems.
Can someone give a hint on how to find the problem?

Some updates...
Tried to run with only two memory sticks, no problem with that. Even if I switch one it works. But with three it crashes after I exit witcher 3. Wierd since I can play the game without problem.
Ran some memtests one only one stick in. Only got errors in the "hammer test" which I guess is ok.
Put all four memories in again and ran memtest over the night. It ran one pass and after that the comp shut down and rebooted.
Downclocked memory to 1333 and ran 4 passes memtest without any crash. Some hammer test errors only.
I'm now trying to run at 2200 and it seems fine. I can play witcher and exit without any crash.
Is it the memory or the MB? Or just a bad combo?

MSI X99 SLI Plus - Won't Post

I've got:
Motherboard: MSI X99 SLI Plus
Processor: Intel Core i7-5820K
Memory: G.Skill Ripjaws Series 16GB (4 x 4GB) DDR4-2400
Power Supply: EVGA 850W 80+ Gold Certified Fully-Modular ATX
It's a new build and I can't get it to post. When I try to turn it on, a red LED located next to the 24 pin ATX power connector comes on and will not go off until I cut the power at the Power Supply. I can't find anything online concerning the red LED. Is it some overvoltage protection? An issue with the memory? I'm at a loss trying to diagnose this. Please see the images below:

Hello.
I'm having the exact same issue.
My computer was running with no issues for over 1 month and today when i tried to start it this exact issue happened.
The lights on the rest of the motherboard are working (CMOS, Power, OC Genie) but it won't post.
I have tried to reset the CMOS, re-seated and tried various configurations for the RAM, tried both BIOS and OC Genie on and off and the issue remains.
Could this be a PSU issue? If so, would the remaining lights work?
Anyone else had this issue and how did you fix it?
Thank you in advance!

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.

MSI X99 Sli Plus can't boot Quad Channel

Hello,
some days ago i bought my new x99 Sli Plus.
I installed everything, right now it's running with a 5820k and 2x4 Gskill 2400 Mhz ddr4.
The main problem is that the system can boot only with 2x4 Block in the DIMM 1 and DIMM 5 position.
If i try to use all my DDR4 modules ( actually 4x4) the system wont boot.
I put in triple channel (3x4GB ) in DIMM 1-3-5 and in quad channel (4x4GB) in DIMM 1-3-5-7
No Signal and no boot image.
I've tried some Corsair DDR4 running at 2666.
Same problem.
It only boots in dual channel on DIMM1 and 5.
that's how i insert the modules.
Thanks for the reply.

Hi,
Is my understanding towards your post correct: your system boots only in Dual Channel, but also only when using slots 1&5?
Try each slot individually with only 1 RAM stick.
Check around the CPU socket and RAM DIMMs looking for any colour changes, smell, scratches or anything like that. If you find nothing, then my last suggestion is you check the CPU socket looking for bent pins (make sure to use magnifying glass and bright light).
As additional,possible, solution:
There was someone with pretty similar issue. From my understanding, what they did is that for every time they've inserted a SINGLE stick, they went to BIOS settings, saved and shut down to insert another one (saved just to make sure BIOS/motherboard recognised the RAM stick inserted).
So my suggestion for now is:
Go to BIOS as with 2 sticks.
Manually change timings to: 15-15-15-35, 1.2V (check box of the RAM to make sure what they are, but according to GSkill that's timings used for 2400MHz DDR4)
Save and Shut Down.
Insert 1 stick (to appropriate slot). Try to boot.
If boots, go into BIOS, check that timings remained unchanged, save and shut down. Do the same for 4th stick.
If you find nothing, and nothing works, I suggest you contact the seller.

X99 SLI plus and Quad Channel issues

Hey guys. I just managed to get some time to throw together my new rig, and am experiencing a very frustrating problem.
I bought the ms9 x99 SLI plus, 4x4 gigs of G.Skill ripjaws 2666 ram, and a 5820k.
I initially put it all together, and it wouldn't post. After a process of elimination I discovered it would post with 12gb of RAM in slots 1,5, and 7. But as soon as I add one to 3, it's hooped. It also won't boot with 1,3,5, or 1,3. It will boot with 1,7, just 1, just 7 etc.
I've browsed the forum and found that this problem with these exact parts has arisen in the past, but I couldn't find a definitive answer. I also took a look at the CPU socket and didn't see any bent pins.
I installed windows fine, it runs fine, installed drivers etc (and its hella fast), but I do need that additional RAM for work. I'm planning on updating the BIOS tonight, and I tried clearing the CMOS early on.
Also I know its not the RAM as it boots with each stick by themselves. It seems to be a Quad channel issue, or a DIMM3 issue.
Any information is greatly appreciated. It's a super sexy board and I'd hate to have to dismantle, send it back, etc. I'm going to Hawaii in a week and was hoping to have all this working.
Thanks in advance!

Unfortunately you will have to. There is no magic and this is obviously hardware issue, whether it's the board or CPU.
Start with inspecting CPU socket pins. You will need a magnifying glass or you can take clear macro pictures of the socket.
Best do it on a bench outside the case, any non-conductive surface will do, wood table, cardboard etc. don't use antistatic bag.
Be very careful when mounting/unmounting the CPU, do not touch socket pins and CPU contacts with your fingers.

X99 SLI PLUS VT-d

Hi,
Was wondering if anyone knows if the X99S SLI PLUS motherboard and its BIOS supports VT-d?
Thanks

Hi,
Newest motherboards support pretty much everything, as long as the CPU allows for it. So check spec of the CPU you want to buy and it should tell you whats supported.
Though for 2011-3 I guess its supported even with cheapest CPU available for it

MSI x99 SLI Plus Unstable

I just finished building my new PC with the following specs:
MSI x99 SLI Plus
I7-5820K
16GB Corsair LPX 2666-15 Ram
Evga GTX 980 SC
Evga G2 SN 850W
I have been experiencing system instability. I updated the bios to the latest 1.3 firmware. XMP Profile 1 enabled.
My PC randomly freezes unable to recognize keyboard or mouse inputs. I must hard reset at which time it reboots normally.
I ran Memtest86+ & it returned 8 errors during the first pass on test 6. Memtest86+ would also freeze during testing. I subsequently ran Windows Memory Test for 10 passes with no errors or freezes. I ran Memtest86 with all 12 logical cores in parallel for 25 passes with no errors or freezes. I reran Memtest86+ and have not been able to replicate the errors or freezing.
Today the PC froze & rebooted on its own. It was as if the power was being tripped as it would die turn on die turn on and then finally booted to a blank screen. The strangest part was that the on-board motherboard reset wouldn't work. I pressed the switch and nothing happened. I was able to reset the PC via the front panel switch. When the PC rebooted it displayed an error message about an overclock instability. I HAVE NEVER OVERCLOCKED the CPU! The only change to the bios was enabling XMP. The problem is very random and intermittent. Is it the Motherboard or RAM?

I upgraded my PC a month ago with this bundle
http://www.overclockers.co.uk/showproduct.php?prodid=BU-023-OG&groupid=2833&catid=2512
which has the same MB/CPU combo and have been experiencing similar problems regarding stability. I've updated the BIOS to 1.3 and have run the Windows memory test without error.
I've tried several OC methods - the Overclockers UK setting, OC Genie and my own modest OC which involved just changing the CPU ratio to 38.
The Overclockers OC has never run successfully while the other two seem to run for one session OK but when I switch off then restart I get the 'Overclock instability' message.
It seems to run OK at the default setting though booting up can sometimes be problematic with it freezing intermittently at the MSI Logo page or at the Windows screen just before the animated logo starts.
Resetting then either solves the problem or produces the Windows error screen and selecting 'Start Windows normally' solves the problem.
BIOS B which I have never updated seems to run without issue.
I'm reaching the conclusion that this MB is inherently unstable at anything other than default settings.

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 X99 SLI PLUS Memory Issue

Guys,
When I try to do Quad Channel DDR4, the system will not post. Currently, I have an 8GB Sticks in Slot 1, 3, 5. When I place a stick into slot 7, the system won't post. If I remove one from 3 or 1, it will post. Currently able to use 24GB/32GB. I opened a support case and they told me to re-seat my CPU and check my power supply... not impressed. I see BIOS .162 floating around the forum not sure if that would help.
Also to note, I have moved the DIMMs around to different sockets, I had one that showed up in socket 3 as 4GB, swapped socket 5 and 3, both now show 8GB.

It's on the compatibility list, may not be compatibility problem...
http://www.msi.com/support/mb/X99S-SLI-PLUS.html#support-mem
Try clear CMOS, if it still have problem...
You can also try to flash to BIOS 1.62 to see if help or not.
Are you able to try on another motherboard, or borrow another DDR4 to test if defect mem-slots?
I have taken the following steps:
1. Upgrade BIOS to 1.5
2. Reset BIOS to Default State
3. Reset CMOS
4. Moved the DIMMs to different slots, including the one I cannot place in the system since it won't post with a 4th DIMM.
As noted, for some time, I was not able to get more than 20GB to show up in the BIOS, only after re-seating and moving DIMMs around was it finally able to see 3 x 8GB sticks. Are you able to give me the errata for the 162 BIOS as well as the "Fix/Change" list I'm all for giving it a shot, just want to know what I'm getting into.

MSI X99S SLI PLUS - What a Nightmare!!

Hi There...
I have purchased the board X99S SLI PLUS.
But since day one, has been a real nightmare to work with it...
I have a 5820k CPU and 32GB 8x4gb GSkill DDR4 2400mhz black.
I have flashed both bios to 1.20, to try to improve my situation to no avail...
I still have random boot problems, where the boot process stops on the "B4" reference on the lower corner right...
That happens when i do some restart on the OS for exemple...
Some times it hangs there and don´t go anywhere, other times it goes to the bios screen and do the POST.
When it hangs i have to press reset to restart the system and at that time it posts normally.
The other issues, are allready inside the bios....
Sometimes the bios hangs from nothing... like when i want to the Sensor monitors, or when i apply the settings...
Last time i think the bios went corrupt, because when i pressed reset the power light and hdd don´t light anymore and there is no action on the POST...
Have to switch to the Green BIOS, to get the system up again...
This is a very bad bios product, and i don´t really understand why theses products don´t have a better quality control.
Now i have a NON FUNCTION BIOS on the blue side, and a problematic bios on the green side.
Also... There is some memory problems on Windows 8.1, because i have allready have some random BSOD (more when i activate the XMS option).
Also there is some kind of problem with Samsung SSD Rapid Option and this board, because i also get some BSOD refering the Rapid process.
To reference, my system is NOT OVERCLOCKED, the cpu are at default and so is the memories...
What can be done?
- To recover the corrupted and failed blue side bios
- To resolve the hangouts on boot sequence that stops at "B4"
- To resolve the random lockups inside the bios (THAT corrupts the damm BIOS)
- To improve reliability of this Board...
So far im not impressed with this product... I was expecting far more from MSI, after i have a good experience with my latest Z77 Gamming board.
I really need help here because i do need my system to work...
Best Regards,
Paulo Eduardo
PS: Sorry for my english, but that is not my native language...

Hi LPC
Would you happen to have anything connected to SATA port 5 or 6?
I cant get my motherboard to recognize HDDs in those two ports. 1-4 and 7-8 works fine. Just not 5-6.
Just wanna figure out if my board is defect or if this is a general issue.

Overclocking X99S SLI PLUS with XP941

Hello everyone. I'm trying to overclock my CPU and RAM.
My setup is as follow :
X99S SLI PLUS (latest bios 1.6)
5820K
Gskill F4-3000C15Q-16GRR
Samsung XP941 as boot drive
As long as I don't touch the BCLK everything's fine. I can achieve without effort 4.2 Ghz on the core and 3.7 Ghz on the ring.
But Then, my DDR4 is stuck at 2666 Mhz.
As soon as I try to level up the BCLK (even by 1Mhz), the board boots and CPU and RAM are OK but the XP941 isn't seen by the board anymore. It's very strange ! I don't get the link between the 2 : why is the BCLK affecting the PCIe or Sata system ?
So, in these conditions, I cannot achieve the 3000 Mhz possible on my RAM (which would require a 125 Mhz BCLK). It's kinda disappointing.
Is any of you experimenting the same phenomenon ? How can you explain ? Is there a solution ?

OK. So I tried again and took some snapshots.
First, I found a bug with this new 1.6 version of the Bios. Hope it won't crash ... My HDD are not recognized anymore !!
Then I tried to play with the settings. You will see below what the bios gives me as possibilities. Wether I enable or not the XMP profile or select the 200 Mhz or 266 Mhz reference clock, I cannot set the memory to 3000 Mhz !
So to summarize :
I cannot raise the BCLK of the CPU or my M.2 SSD is not recognized anymore and my OS won't load
I cannot set my memory setting to 3000 Mhz whatever setting I'm trying
I found a bug in the new bios version in the list of Harddrives connected to the board
Not a happy week so far ...
DDR4 options with 200 Ref clock (same with XMP enabled) :
DDR4 options with 266 ref clock (same with XMP enabled) :

GTX 980 Classified (also have a 740 for testing)
4x4 gig DDR4 2400 (Installed in 1-3-5-7) G.Skill Ripjaw
EVGA NEX 750 G Modular power supply
NZXT Kraken X61 cpu cooler
EVOS 250gig SSD
WD 1b HDD and an HP Optical drive
Hook everything up, and no signal to monitor whatsoever. Have tried unhooking EVERYTHING except bare minimums and still nothing. Does same thing on 2 different cards. Any help?

Hi
Try >>Clear CMOS Guide<< with power cord removed
Also try with single RAM stick and outside of the case, on non conductive surface like wooden table or motherboard box.
