[SOLVED] Z77 Mpower PCI LANE problem [MSI 7751]

hi peoples i'm a new here as new user of MSI motherboard, this is my first MSI motherboard, and i allready have a problem with it.
as the manual suggest, for a single gpu configuration i should use pci_e2 (page 1-19)
i've tried GTX 260 216sp no go , black screen no system post ,and pressed reset button like 10 time, didn't work, it worked once and never again, and gpu-z shows [PCI-E 16X2.0 @ X4.0]
i've tried AMD 3850x2 no go , black screen no system post
i've tried 9600GT no go , black screen no system post
i've tried 9500GT no go, black screen no system post
i've tried 9800GTX no go black screen no system post
then each of this vga shifted on pci_e5 and worked at the first system startup
is the mainboard faulty?!
PC SPECH :
i7 3770K @ stock speed
Mainboard : z77 mpower latest bios installed
Storage : SSD Crucial 64 Gb
PSU : enermax revo 85+ 1050w
Ram: corsair platinum 2400c9 2x4gb
Windows Xp 32bit
Windows 7 x64 [7601]
i may think this board is faulty isn't it?
the previous mainboard was an Asus Gene Z77 wich didn't give me any kind of problem, cpu ram and psu were the same and worked perfectly.
is there a way to fix this or i should send it back!?
thanks for the help.

Remove the board and make sure there are no extra stand off or screws shorting the case.
[cut]
just tried , no go at all ...

If you have tried all the applicable suggestions previously mentioned in this thread, try the newest Beta UEFI/BIOS found here;
>> Beta <<
wich one please? i see so many ...
edit: found. i'm trying now.
Quote from: Froggy Gremlin on 21-October-12, 12:13:35
Presume in GPU-Z it was reading 2.0 @ 8X? I think the suggestions are correct. This is a classic behavior of bent or damaged CPU socket pin(s). Could be a faulty PCI-E slot, errant standoff underneath the mainboard, or even a more rare faulty CPU. Uneven mounting or torque pressure of the CPU cooler could also cause this behavior.
what does it mean? should i still have to wait like one month or much more to get a new board since it arrived faulty?

[SOLVED] Z77 Mpower can't detect second graphic card

Hi everyone
I'm experiencing a problem with my Z77 Mpower.
It's not able to detect the second graphic card.
The complete configuration includes:
Z77 Mpower
i5 2500k
2*4Go G.skill 1866MHz
GTX680
8800GT
Crucial M4 256Go
Corsair AX750
The idea was recycling my old 8800GT as a dedicated physx card
Due to massive cooling the GTX680 will be installed on the second port
Both graphic cards works perfectly when installed alone and I also tested with a GTX570 and results are the same
When I install only one card, it works on 1st port at 16x or 2nd port at 8x,
but if there is 2 cards installed only the first works and bus-width is 8x according to CPU-Z, the second one is invisible in windows, GPU-Z or driver
I didn't tested the 3rd port because my sandy bridge has limited pcie lane
I tested it with bios 17.4 and beta H53, results are the same, I also tried with and without 6 pins power supply on the mainboard and the problem is still the same.
I tried this graphic cards configuration on a gigabyte z68 ud4 and same cpu, ram, vga and psu and it works perfectly.
Is there a bios setting to enable multi gpu ? (tried to enable igp multi screen without result)
Is it possible to have defective pcie port for multi gpu when all pcie ports works alone ?
I have another question about this motherboard
is it possible to have a dynamic vcore related to eist while overclocking ?
on the gigabyte z68 ud4 it's possible by setting vcore on normal and playing with load line calibration and offset
on the mpower this settings appears in bios but are not graduated the same way and I don't understand how they works.
Thanks for your help

Thanks for your help flobelix
I already tried and benched this physx configuration on my old gigabyte motherboard
in non physx games the 8x limitation barely don't affect the gtx680
in physx games the 8800gt isn't fully loaded and framerate is near the gtx680 alone with physx disabled.
this configuration gives physx graphical bonus without affecting framerate
the 120W limit of the MK13 may be for fanless use, I have 2 90mm fans attached directly on the heatsink and under furmark the card runs 20°C lower than stock cooling and is very silent
I also kept the stock molded metal plate that cool the power supply and ram under the MK13
But due to this cooling this card can't be installed on the first slot
on the gigabyte until you set the dedicated physx card in the driver both cards and all outputs on cards sends the same signal to screen (bios screen is also sent to all cards)
on my mpower only the first sends signal to screen, but i should be able to set (only for testing purpose) the 8800gt as main device and the gts680 as physx card
unfortunately it don't work because it looks like when a card is plugged on 1st port the mainboard disables the 2nd

Radeon 7950 wont work in primary Z77 Mpower PCI 3.0 Slot?! Help!

I bought an MSI Z77 Mpower motherboard with I7 3770K and HIS Radeon 7950 ICEq Boost Edition 3gb back in January.
Ever since I built the computer it WILL NOT boot up with the GPU card in the first/primary PCI 3.0 slot of the motherboard, it just startsup with a black screen, no bios, post or anything. Just a black screen with the fans going.
This card will boot up perfectly fine in the middle PCIe slot. But it runs slower in this slot, at PCIe x2 3.0.
I had the card RMA'd at the time and it came back as fine, and it works in my brothers computer too.
It just WILL not work in the first PCIe slot on the Z77 Mpower.
My much older Radeon 4850 works perfectly fine in the primary/first PCIe slot, and computer boots and works as normal.
So it seems to be a Z77 mpower - HD 7950 incompatibility?
Can anyone advise on this because its doing my head in?!
BIOS is flashed to the latest version as of yesterday and still no joy.
Many thanks
Chris

I'd love to swap to Z77-Mpower, but it doesn't have any PCI slot needed for my M-Audio sound card ;-)
I forgot to mention when we've been checking hardware: if I were you, I'd swap HIS 7950 to another 7950 (Asus, MSI, preferably Sapphire, whatsoever) to check compatibility instead of selling out motherboard. It's great piece of hardware, so I'd blame graphic card first than motherboard - for incompatibility. HIS is one of the cheapest vendors (not the cheapest, like VTX3D for example), so maybe it was a reason.
It's a proof that M-Power works with other 7950s:

Z77 Mpower+ GTX 295 problems.

Hi all
I have an Z77 mpower motherboard with Avexir MPower Series 8GB (2x4GB) DDR3 PC3-19200C10 2400MHz Dual Channel Kit and a i5 3570k.
When the mobo is at deafults in the bios then all is ok..not one problem.
but if I do a small OC [email protected] using turbo and use the XMP on the ram
Then most times it gets to windows the I get a black screen and my monitor says "No video input"
Now on my 295 dual pcb I have a blue light(for power)and a green light that comes on when I am connected to a screen.
What I have noticed is that for some reason the mobo will switch off the screen side of my 295(the green light is now out)
and some times when it gets to the windows logon screen it turns off the power light!
At the MSI mpower page it says that a GTX 295 with the firmware of 62.00.6C.00.01/02 has been tested
my firmware is 62.00.45.00.02(P0657-7000) not the same so?
I have tried my 295 in another i5 mobo(gigabyte) and all is ok, my power supply is a Silverstone 650W SLI.
Any help would be good
Thank you for your time.

There is another user with this exact error. Best to contact MSI, I'll send them an email and see if there is a known issue.
Please let me know which ME version is installed. Check in UEFI bios for this.
Thanks
>>How to contact MSI.<<
Edit: Try this version as well:
http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=22092&keyword=management+engine&lang=eng
I also recommended to the other user to remove control center then do a registry search for it and delete any left over keys and files. Then re-install see if it helps.
Thanks xmad
I will uninstall control centre in a bit and do as you say.
I have told MSI support but all they say is they can't replicate the problem and they never heard about it.
The ME driver is installed this "please replace the ME version" will it cause any other problems other than control panel?
because I can live with out it. I will look at my ME version when my 480s come tomoz.
As I am hooked to my monitor using the built in graphics and it don't like my monitor lol.
Thanks again...Hello MSI support..please pay these guys or give them some great freebies..thank you

Z77 Mpower + 2500k OC Problem with voltage

win 7 64bit pro
2500k @ 4.6
z77 m power
2x8gb kingston red 1600
2xgtx 780 ref
i recently changed to this board from a z68x-ud3h-b3. But im having a problem where i can't make the voltage drop on idle. I currenly have my cvore set to 1.35 max load during IBT or gaming is 1.344 and degree's are fine. I have C1ST enabled and some of the other power saving features disabled as well as the Hybrid power Offset @ 100%. Is there a option on this board to make it drop to 0.9xx on idle ?? thanks in advance !
PS : is there a way to manually set the dram voltage ? it's currently set to auto but when i try to type in 1.5 or 1.6 it just goes back to auto ?

Club was my cell phone auto correcting.
Was intending to say cpuv and cpu multiplier.
long duration power limit 4096 My z77 = 255
Long duration maintained(s) 1 My z77=2
Short duration power limit 4096 My z77 =255
I set my turbo multiplier to 45 x
Quote
Also do u mean the core ratio limit for turbo multipliers and set them manually too 46 if I want a 4.6 clock and leave multiplier and voltage on auto and I have set then droop to 75%
Yes, although 46x was not stable on mine. Most users report being able to reach 45x w/ all power savings enabled, 46x would require 100% vdroop and most likely disabling some power savings features.

Z77 Mpower Black Screen Problem - Debug Led UpsideDown

Hi guys! from some days I have a problem with the motherboard. I bought new in November 2013. now the PC crashes giving me black screen during game sessions, during work session and sometimes even when IBM in the bios and the PC do not responding to commands. memtest does not detect problems with the ram. the video card works at very low temperatures being liquid cooled, as the CPU. I can not check the code on the debug panel because I realized just now that one of them was soldered upsidedown :( it pass all the benchmark, from 3dmark to ibt, unigine valley and heaven
what should I do??
here is a photo with the debug led POST2 soldered upside down. it show me symbols like the Pipboy of a Predator
my config
i5 3570k
4x2GB corsair vengeance 1600
2x7950 dualx
samsung 840 120GB
caviar black 1TB
caviar green 3TB
win 8 64bit pro

msi support told me that I can do rma. but he told me that surely receive a mainboard refurbished in change of mine and not new. total disappointment

Z77 Mpower USB2 issue under Win8.1 only

Hi,
I dont know where to ask this anymore, no-one answers so i think it can be bios issue of msi z77 mpower motherboard,
The problem is that the frontal usb2 port does not work, the device is not appearing in device manager and disk managment sections.
The only way to make it work is to plug in the device before turning on the PC, so windows will run it normally.
This happens only on windows 8.1, I have already tried to reinstall it but nothing is changed... can anybody tell me whats going on and how to fix it

All of my USB3 ports are working fine and never had any kind of problem, as i said, the only way to make USB2 work is to plugin device before PC turn on, so my Mouse and Keyboard which are attached to the backside USB2 ports will always work.
Here is the full spec.
Board: MSI Z77 Mpower
Bios: Version 17.12
VGA: MSI GTX680 Lighting
PSU: PC Power and Cooling Silencer MkII 750W
CPU: Intel Core i7-3770K
MEM: Gskill RipjawsZ 2400MHz 2x4gb F3-2400C10D-8GZH
HDD: WD Caviar Black 1TB

Z77 mpower BOSD when using XMP Corsair Vengeance CMZ8GX3M2X1600C8B

Dear everyone.
Just like you I have joint MSI community by buying an Z77 Mpower . The Board has great quality and look, i Happy with it until i have some BSOD recently .
Here my rig:
CPU: I7-3770K.
Main: MSI Z77 Mpower (Bios H30 on MSI Website)
SSD: OCZ Vertex 4 128 GB (OS)
HDD: 2 SG500GB Raid 0, 2 TG WD Green
VGA: Asus GTX 560Ti Top DCII
PSU: Cooler Master Silent Pro 700w
Ram: Vengeance — 2x4GB (CMZ8GX3M2X1600C8B) (at slot 2 and 4)
When i install OS and other apps there have no problem but when i using XMP profile to have my ram work at 1600MHz and set Dram voltage to 1.502, i had BOSD every 20m . What the problems here? Can anyone help me how to set these ram at 1600.
When i check with memtest86+ every thing fine with dual ram, i run it for 10 pass without errors. Then i check 1 stick at slot 2 it's show CAS 6-6-6-20 even i have set XMP profile at bios, is it OK? But then it still had 10 pass without errors.
I check again with slot 4, 1, 3 every thing show 9-9-9-24 when at memtest.
I have try everything but it seem only work with default setup (1333MHz). I wonder if this Ram, Main or PSU error.
Sorry for my english.

Your XMP profile will set timing automatically.
Let me know if my solution worked.
Sorry i mistake in memory it must be CMZ8GX3M2A1600C9 code however i have set bios at spec 9-9-9-24 BUT IT keep on BSOD ...
I'm tired now , what is the correct setup to have 1600Mhz. I test both stick by memtest86+ all pass without any error.

Problem with starting msi z77 Mpower

Hello
i 've just bought a Cooler Master Silent Pro Gold 800W
and a mobo msi z77 mpower(today)
i have this problem
i have tested the psu with 2 different mobo (the msi stated before and a asus p8z77 v pro) and in both cases the psu fan runs for few seconds and the it stops.i have tried it with and without cpu , with and without case fans , i have the same problem it turns the fans for few seconds and then it stops as if dose not have enough power.
tested the psu with the paper clip test and it works , but when i put the 24 pin connectors and the 8 pin connectors on the motherboard it dosen't. Maybe i do something wrong ?
I've speak with tech support from cooler master and it seems it's not the psu
honestly i don't know what eles to try /do
can you help me?
thank you in advance

To go a step farther, when the board is outside of the case, you should have a monitor connected to the onboard graphics or a discrete card, 1 stick of RAM in the primary DIMM slot, and CPU with it's cooler for initial startup. Be sure to test on a non conductive surface of unprinted plain cardboard or an untreated wood surface.

MSI Z77 MPower sound problem

I have MSI Z77 MPower and i have problem with sound. When i play audio i have feeling that sound automatically volume up and volume down. When i uninstall THX i have feeling that is everything OK but sound is not loud like before.I try on THX turn off smart volume and cristalyzer but problem is still here. Can you help me.

I had the same issue with an early version of THX, have you downloaded the newest version from the website?
>>MSI Downloads<<
Update all of your drivers and re-test. In my case I just un-installed THX until the next version came out and it's fine now.

BCLK STUCK!!! BIOS 17.6 Problem with Prefetcher???MSI Z77 Mpower

BIOS 17.6 added the new CPU features.
I think the new BIOS CPU features of "Hardware Prefetcher" item and "Adjacent Cache Line Prefetch" options are part of the problem. When I disable hardware prefetcher my memory performance shoots way down. BUGGY!!!!

Msi z77 mpower sli and areca raid controller

Hello, i own an Msi z77 mpower and i have recently upgraded to an SLI config (dual GTX680's)
The problem is since then i can't get my hardware raid card (Areca arc-1212, with latest bios) to work, it bleeps but i don't get the raid info screen or menu.
I've put both the graphic cards in the top two pcie 16x slots (PCI_E2 and PCI_E5) and my Areca in the bottom one (PCI_E7)
As far as i understand i should be able to run 3 pcie cards at 8x/4x/4x right?
The only slot where the Areca works is the PCI_E5 slot, and i can't put a GTX680 in the PCI_E7 slot because of spacing.
I'm also running a Xonar sound card in one of the pcie 1x slots (PCI_E4)
Running with a Intel I7 3770k and 4x4gb of ram and Windows 7 x64.
I'm running the latest beta bios.
Please help!

Quote from: jhroom on 28-February-13, 07:39:35
Thanks for the fast reply!
But what use does the 3th slot have then?
Also a 4x gen3 slot has the same bandwith as a 8x gen2 slot right?
I feel a bit mislead, knowing this i would have chose a different board.
Other boards will have the same problem. The CPU has 16 lanes to divide and Nvidia demands 8/8 for SLI. That leaves no lanes left for the third slot.
Using CrossFire should leave you 8/4/4 as AMD doesn't demand 8/8 for CrossFire.
You'll need the use the slots using the lanes coming from the PCH if you want to use additional PCI-e devices.
The X79 platform might suite your needs better. That has 32 lanes to divide from the CPU + the ones from the PCH.

MSI Z77 MPOWER ATX rebboting over and over.

Hi guys! i really hope u can help me.. i recently bought a new computer and yesterday i built it together. Everything looks fine and seems good. THOUGH!! when iam starting it up it constatly restarts after like 5 seconds? I unplugged the GPU which i putted in PCi-E slot 2 to make more room in the barebone. After i unplugged it seems to boot up normally? Anyone have any suggests? these are the components iam using:
MSI Z77 MPOWER ATX
Intel Core i5 3550 3,3Ghz (Ivy Bridge)
Corsair 16GB (4x4096MB) CL9 1600Mhz VENGEANCE

What happens when you put the vga in the top PCIE slot?
Are the 6 / 8 pin connectors hooked up to the vga securely?
The 2x 4pin cpu connectors (JPWR)
Do you have another vga to test the pcie slots/ another computer to test the vga?
Inspecting the pins would be a good idea as well as that is a common cause for pcie lane failure.
Also, sometime the default bios for some boards don't work with the 660 vga's try the beta:
