really? the hassel you get with a chiller on a wc loop you might as well just get a ss phase and really get good temps
To each their own! My outlook is if it can't be done on air, it don't need to be done!

Impossible boot with Z77A-GD55

Hello.
First of all,my english is very BAD,so i'm sorry for errors.
I have a PC with a Z77A-GD55 Motherboard.It worked great for 2 months,but now i can't boot my PC.
When i try to boot it,the case fans and the CPU fan spin,but after 10 seconds the boot process stop and 2-3 seconds later it restarts.I can't access windows and the Bios too.
Where is the problem?I was thinking to update my BIOS but i don't know how to do it without entering windows or the bios.
Please help me!
Thank you,and sorry for bad english!

Oh,ok.i Will try it tomorrow,here in Italy is night now
Where I am it's night too, same time to be exact .

Other ideas?
Take machine apart and try barebone as you already did (only PSU and Motherboard with Ram,CPU and CPU Cooler) outside of case on a non conductive surface (e.g. wood).

Question about Z77A-GD55 Overclocking

Hello there, i have just upgraded to 3570k now with MSI Z77A-GD55. So far the max overclock i got without going 90C is 4.4Ghz (with Thermalright Macho as the cooler) It is achieved with these settings:
1. VCore: 1.265V
2. VDroop Control: Auto
3. OCP Expander: Default
4. VRM Engine Speed: Auto
5. XMP: Enabled @ 1600Mhz
6. CPU Multiplier: Auto
7. Core1/2/3/4 Multiplier set at 44Ghz
8. Base clock: 10039 (to negate lower default base clock)
9. Long Period Maximum Wattage Maintained: 200W
10. Short Period Maximum Wattage Maintained: 250W
The questions are:
1. When i change VDroop Control to other than Auto., the voltage when loaded getting dragged lower compared when the item is left at Auto. On Auto i got 1.240@load and 1.256@Idle. When using 25%, i got 1.230@load and 1.248@idle. Stange.. so can anybody explain this part? Or the VRM speed should be increased to 1.5x?
2. Does this board support overclocking with Vcc set as Auto, i mean automatically increase the Voltage when needed?
3. What's the relation of Internal PLL Overvoltage with PLL voltage menu? I read that to achieve lower temperature in IVB, lower PLL will help; So in this case, what's the best setting for them?
4. Have been trying to OC to 4.5Ghz but the temp goes past 90c. Anybody have any idea or suggestion to improve the situation? The problem is i can't lower voltage to less than 1.3v for 4.5Ghz. Otherwise, some application will hang on the background while testing with IBT. Any trick to circumvent that? I'd like to keep C1E state enabled though (C1E level is set to Auto although i am free to tinker with shallower level like C2 only, but still i don't want the energy saver feature turned off). What i'm concerned with is the Vdroop doesn't work correctly so higher voltage is required for 4.5Ghz OC (which burns the temp obviously).
5. I have DDR3 RAM of Team brand set at 7-7-7-21@1600Mhz via XMP at 1.65v. The strange thing is the Command Rate is set at 2T. when i override it to 1T, the read performance goes down to 13GB/s instead of 19GB/s with 2T in AIDA cache and memory benchmark. What could be wrong?
6. In CPU Hardware Monitoring, it says that my CPU is only loaded @+-72Watt with those settings above. Is it bug in monitoring app or what?
My Specs:
1. 3570k
2. Z77A-GD55
3. 4GB Team DDR3 7-7-7-21 @1.65v
4. Geforce GTX 570 EVGA SC
5. Crucial SSD + RAID 1 @500GB
6. PSU Seasonic X750
That's all i suppose, please help me with some answer Thanks.

If reading the Intel datasheet correctly, native supported RAM selection should be DDR3 1333 or 1600 (11 11 11) that is 1.50v. based (+ or - 0.075v's tolerance). RAM that is rated to run at 1.6v. or 1.65v. doesn't appear to be well suited for this platform's CPU IMC. There are offerings now showing up with speeds of at least up to 2133 @ 1.50v's with most likely even more to be developed and released.
VDroop is a voltage tweaking feature. Use it to lower the voltage too much and the system might not boot.
It is what it is. Each CPU will have it's own minimum voltage it needs to work at a given clock. That is what VDroop is for. Find the point at which it won't boot or remain stable anymore using the lowest possible VCore.
>> Ivy Review <<
Reading your suggestion and knowing that my RAM is set to run at 2T Command Rate, i tried to lower it to 1.575 and 99% stable, but crashed while doing IBT the 4th loop, so bump it up a little bit more to 1.6v.. Going to try it with IBT now love that tight latency of my module so no RAM upgrade come to mind so far.
About vdroop, so are you saying that this vDroop control is to give the CPU more vDroop? weird to have a board that not pushing better LLC but giving you more vDroop on change

Nvidia 650x2gig fails in MSI Z77A gd55: need NVidia drop-back card.

Gents:
Running UBUNTU 12.04 under:
Xeon 1240.v2
MSI Z77A gd55 : BIOS V1.2
2x8 gig Crucial ram
320 gig SATA
"ULTRA" 650W PS @ 60 amps on 12 volt rail
Auria 27" 2560x1440 monitor
My legacy gtx9400 vidcard will push the monitor, but my new purpose-bought EVGA 650x2gig fails to generate **any** response (no signal) in the monitor. An EVGA tek said it looked to him like a mobo BIOS/vidcard incompatibility. He advised flashing BIOS; I am very **risk adverse** and never flash BIOS. So assuming the problem is BIOS clashing with vidcard, then I need a downmarket/older vidcard. What is a good -- older -- midmarket Nvidia vidcard ( AMD Linux drivers inferior ) that the V1.2 MSI BIOS can handle?

Thanks for your interest & comments ... I am stumbling about and know it.
Believe me: the NVIDIA chip EVGA _650 vidcard fails totally in my system. So you say I need BIOS V1.5 to run my 1240.v2 ... and I am **not competent** to risk that/any BIOS flash. That's tuff-titty for me tho I get no error messages from my system. Casual *nix benchmarks are respectable. Unless you consider the NVIDIA-650 vidcard failure an "error message". Very well ... I must work around that issue and not arrogantly try to do what I cannot do. I **can** buy ( for less than $150) & install an NVIDIA_550 vidcard ; if I think it will work. That's my question ... given that a legacy GTX_9400 works and the EVGA_650 fails, what likelihood that a last generation NV_550 vidcard works?
Or .. are you telling me that the early BIOS versions for the GD_55 are well&truly a mess and **nothing** may be trusted to work with them. I still will not risk a BIOS flash, but will climb down the vidcard ladder until some legacy part above the GTX_9400 works! Thanks again for your post and info.

Using your current cpu requires at least bios version 1.5: http://www.msi.com/product/mb/Z77A-GD55.html#/?div=CPUSupport as you have been told before. You may run into problems although it might look ok now.

I don't know what a NV_550 should be but your GTX650 should work fine with a current bios.

Overclocking z77a gd55

hi have simple question but i dont see anywhere about that
i want to know if i have to turn off the oc genie button to overclock a little bit more
thanks

Onboard audio dead on MSI Z77A-GD55

I think my onboard audio on my MSI Z77A-GD55 has broke no matter what it just says not plugged in i've tried a reinstalling drivers, cmos reset and a fresh install of windows but it still says not plugged in.
Digital output seems to be working tho.
Doe's it sound like its dead to you guys and should i RMA the board?
The nvidia hdmi audio works fine its just not plugged in on the pic.

Quote from: Bernhard on 31-October-12, 22:22:06
Which are you using ? front panel or I/O ?
Did you connect the front case panel ? If so, have you ensured that you used the HD one ? Disconnect the front panel audio for now to check if a short may be causing this problem.
I've tried that and all audio output are doing it once it randomly said the speakers were plugged in, but even tho windows was showing it was playing sound my speakers and my headphones that both 100% work didn't play anything

Z77a-gd55 problem

So I just bought a new system.
Z77a-gd55
8gb DDR 1600mhz corsair vengeance
corsair tx650m psu
I7 2600k CPU
Had my system running, on the second day I left downloading a patch for a game. When I returned my computer was off and now won't boot. 90% of the time the led 1 light flashes and the fans spin then the system turns off . The other 10% it stays on but with the dmos alert and led 1 on and it won't shut back down. I have tried clearing cmos and am currently running bare bones tried each ram slot individually with both sticks of ram. Also I had not tried to OC.

Only insert one RAM module in the slot closest to the CPU.
Disconnect the HDD and only leave your DVD connected.
Then do a full CMOS clear with power cord removed.
Also remove the CMOS battery for 10 mins or so. Recheck all your power connectors.
If you have a GPU card, which you didn't state, remove that as well and only use the onboard graphics.
Test with another known working PSU.

Msi z77a-gd55 xmp missing after add ram

hi
i have msi z77a-gd55
at start i have 2 stick of ram of kingston khx1600c9d3 and i have the option to set xmp mode
but now i install two other stick of ram the same ram buy from kingston
i have done a clear cmos
and the computer boot without problem
but in the msi bios the xmp option desappear and i don't know why
my bios is up to date
anyone have an idea

I know this is not a new tread.but i have the same proublem with my MB msiZ77A i put in 2 sticks of
kingston 8meg each at 2133mhz.and mb, is only showing 1333.at the top of screen.I went down the
screen and Changed the Freq from 1333 to 2133 and clicked Save and shut off the computer. I re booted
and went back to look and at the top of the screen it still says ddr Freq is 1333. but when you scroll down
you can see that the new Freq of 2133 is their.
Shouldnt the bios see that i changed the speed?and also show the NEW speed of 2133.
tks

Z77A-GD55 and Intel Xeon E3-1230V2?

Hello everyone
my Holiday Project is a reconfiguration of my AMD System to a Intel Platform.
The Mainboard for this will be the Z77A-GD55.
My Problem is
i cant find on the CPU Compatibility List (Sorry, you are not allowed to post external links.) the E3-1230V2
I would like to order but only if I can be sure that the components fit.
best regards
MuMMeL

Any specific reason you prefer the Xeon over the i5 or i7 Ivy?
The only real difference is, you will need a discrete GPU card if you opt for the Xeon and you can use memory with ECC.
Here are the current supported CPUs http://www.msi.com/product/mb/Z77A-GD55.html#/?div=CPUSupport

Z77A-GD55 How to enable PCI slots

Insert the video card in a PCI slot does not see. Does not even appear in the device manager. I'm sure my video card works. How can I fix it?
Main Board: Z77A-GD55
Bios Version:
Video Card: GigaByte HD5970
PSU: Xigmatec 700W +80 Centauro series
12v rail Rating of listed PSU:
CPU: i5 3570k
Memory: 2x4gb
SSD/ HDD: 1tb wd black
CPU COOLER: stock fan
Raid Card:
Sound Card:
Any Additional hardware plugged into your system:
OC: No
Operating System: Windows 8 Pro 64 bit

I would suggest removing the CPU and inspecting the mainboard's socket with a bright light and magnifying glass. I am betting you will find some bent cpu pins.
If both card you tested in this board are 7xxx AMD cards, you might want to try flashing the bios first.

Z77A-GD55 XMP option doesnt exist

As showen in the topic the option to setup the XMP profile is not available!
to my Rig:
CPU: i5-3450 (Ivy Bridge-DT)
Mobo: Z77A-GD55
Ram: Kingston 9905403-478.A00LF 4GB x2
Graka: MSI R9 270oc
The bios, CPU-z and Aida64 said that the max takt rate is 1333/667 but there are 1833 sticks
so what should i do
Previos i had the Corsair Dominator 9-9-9-24 1600/800 there was a max shown of 533 not the 800
i know from othere threads in the internet that my ram mobo and cpu are able to setup XMP
what did I wrong are there a option that unlocks the real performance ?

KHX1866C9D3/4G i have 2 in use
so what can i try ?
Edit//
I tryed 800/1600 and the board dont change the actual ddram rate it does not do what i set what the is going i changend the slots anyways 1,2|1,3|2,4 no differenc just 1,2 is no dual channel

[Z77A-GD55] any beta releases?

Any reason you need a Beta ? Best to open a ticket with MSI technical and ask them if there are any new BIOS versions that could solve your problem.
Would a mod please move this and the previous post to a new thread "Z77A-GD55 BETA BIOS".

Z77A-GD55 is mine bad? - Solved

I've just set assembled a new Z77A-GD55 with the following:
Intel Core i5-2400 Sandy Bridge with stock cooler
2 x G.SKILL Ripjaws X Series 4GB DDR3 1600 in sockets 1 & 3
Rosewill Stallion Series RD450-2-SB 450W ATX V2.2 Power Supply connected to JPWR1 & JPWR2
USB keyboard
USB mouse
DVI monitor plugged in to onboard video
I don't have a case yet but I figured I could test the system on the bench. However, with everything connected up, I press the onboard power button and all that happens is:
Power button lights green
DrMOS_ALARM & LED1 flash briefly
The CPU fan starts and then stops
Is it me or is something badly wrong (or both) ???

Not necessarily. What does the manual show? It may dimm2 (black) being the primary. I will need to download and have a look in the pdf manual to confirm.
Added: Yup! DIMM2 is the primary. Another good reason to not load up the board full of RAM sticks is if one is bad, it makes it an added pain to try and find the bad one. Especially with mainboards that have 8 dimm slots.

Z77A-GD55 not booting(boot loop)

hey ...
I got hold of a z77a-GD55 mobo where the previous owner did not know if this motherboard was working or not.
I have installed an i5 2300 CPU and 4gb ram on two sticks.
when I press the start button its turns on and runs for about 5 seconds and simply turns off and on again in a loop.No picture on screen.
All the phase leds turns on.
I have tried all ram slots with one stick of RAM, reset the bios, taken out the cpu and reseated it with new thermalpaste and with / without gpu.
I have only run this motherboard on a cardboard box.
Can anyone help me here?

This sounds like the BIOS was corrupted due to a bad flash. The boot block is probably bad too. I've had this happen when trying to use the M-Flash function.
Download all of the different versions of the BIOS for your motherboard from the MSI main site. Place all of the BIOS ROM files in a FAT32 formatted USB stick in the root directory. Insert USB stick, hold down home key, and power on while holding down the home key. Watch USB activity on the flash drive. If the light on the USB flash drive blinks a lot, then it is loading your BIOS.
If that doesn't fix it, go to a computer shop and have them program your BIOS using an in-circuit SPI programmer. You can buy a cheap one from China/Hong Kong if you feel like doing it yourself.
Good luck.

MSI Z77A - GD55 mother board. Does not start.

Hi
My completely new computer does not start. It's completely dead. (worked fine yesterday)
There is a power button / lamp on the mother board, it blinks continually when power is connected. Nothing at all happens when I press the computers power button or the power button on the mother board.
Is this a problem with the mother board or could it be the power supply that has failed?
thanks for any help at all

My system:
Cool Master HAF X Big Tower
MSI Z77A - GD55 Socket 1155
XFX ProSeries Core Edition 550W PSU
Intel LGA1155 Core i7 - 3770
Corsair Cooling Hydro H60 CPU cooler
Corsair XMS3 1600MHz 16GB Vengance CL9
Gainward GeForce GTX670 2GB GDDR5 PCI-E
Samsung SSD 830 Series 256GB BK SATA3.0
I have yet not tested to do any changes on the hardware. I have only tested switching power cable. (not sure why it would help, but I tried it anyway)
