Z77A-G43 XMP RAM Voltages

I have some Crucial Ballistix 1866 ram installed in my Z77A-G43 mobo and was wondering if the motherboard follow ALL the voltages listed in the XMP profile if XMP is enabled.
Per readings from AIDA64, the XMP profile states a memory voltage of 1.5v and memory controller voltage of 1.3v. If I enable XMP in the bios, does that mean the motherboard will adhere to these voltages? I have no problems with 1.5v memory as that is standard but the memory controller voltage of 1.3v is extremely high. Also, which voltage is the memory controller, is it VccI/O (Vtt) or VccSA (IMC) on a Ivy Bridge CPU?

It usually sets what it reads off the modules programming for DRAM V., timings, and Command Rate. Both I/O and SA are related to the memory operation. I can run RAM at 2800 with only I/O of 1.09v's and SA around 0.970v's, so 1.3v's is way higher than needed IMO.

Download the applicable Intel datasheet(s) for the CPU and chipset, and they will tell you everything you need to know. IMC? It stands for 'Integrated Memory Controller'.

Added: It makes it hard when we can't see a complete signature or listing of all the systems components and hardware. In this case, the CPU is not known, which makes a difference what the IMC natively supports.

MSI Z77A-G43 RAM Problems

Hi everybody,
I have some big problems with my new build:
Intel Celeron G1610
MSI Z77A-G43
2x4gb Corsair Vengeance LD low voltage 1600 mhz 1.35 v dual channel kit
Seasonic 620w PSU
Saphire 7850 2gb GDDRAM5
My system wont work with both ram sticks in. If I only use one of them (it doesn't matter which one) in whatever slot I want, I don't have any problems. However if I use both of them I get bsods or restarts very soon after windows finishes loading. I must also mention that it's almost impossible to install Windows with both Ram sticks in. I almost always get a bsod when the installer is expanding the windows files.
I must also mention that by default, my motherboard sets my ram to 1333 MHz and 1.5v even if the producer says that the ram should run at 1600 MHz and 1.35 v. If I set them to these values myself in the oc menu, they are reset to the default values again immediately after I get another crash.
I have the latest bios and drivers and I don't know what else to try: ( any ideas?
Thank you!

Hi flobelix and thank you very much for your response. I tried your solution and on the next powerup, my pc didn't crash at all and I ran a couple of games and memory intensive programs.
However, unfortunatelly, after I closed the PC for a while and restarted it again, the problems came back. The ram timings don't change anymore in BIOS but the system constantly restarts. I ran memtest for 6 hours last night with both sticks of ram in and it did not find any errors so I can't figure out what's wrong.
Here are a couple of crash dumps:

Since I'm desperate, I'm just gonna go ahead and reinstall windows again. During the last successful pc run (after I took your advice), I ran MSI live update and installed the rest of the utility software. Maybe this did something to my drivers.... I'm really reaching the end of my possibilities :(

Z77A-G43 PROBLEM WITH RAM

hello
I need help, I bought a MSI Z77A-G43 motherboard and a CPU INTEL I7-3770K, I installed everything but when I insert the memory (provided ALL WORKING AND TESTED) the pc does not start, and if I put a model KINGSTON kvr1333d3s8n9 / 2g pC starts, this in any slot of the motherboard if I put 2 equal does not start!.
If we insert the KVR1333D3N9/2G which also is certified in the manual does not start the PC.
I updated the BIOS to the latest version 2.8 but to no avail, the problem persists.
I realized, however, the BIOS reports as the DIMM1 and DIMM2 DIMM3 as DIMM4 and of course the DIMM3 as DIMM1 and DIMM4 as DIMM2.
Can anyone help me?
Thank you very much
Board: MSI Z77A-G43
Bios: Version 2.8
MEM: 2 kingston ddr3 1333 2gb KVR1333D3N9/2G
2 kingston ddr3 1333 2gb KVR1333D3S8N9/2G
Intel Core i7-3770K 3.5GHz (3.7GHz Turbo Boost) LGA 1155 95W

I realized, however, the BIOS reports as the DIMM1 and DIMM2 DIMM3 as DIMM4 and of course the DIMM3 as DIMM1 and DIMM4 as DIMM2.
This is because DIMMS 2 & 4 are the primary DIMMS. (The ones reported as 1 & 2)
So a matched set of Quote

This sounds like defective ram.

Z77A-GD65 - add more voltage to DDR RAM?

Greetings.
I'm trying to OC my ram from 1600Mhz to 1800Mhz. My ram runs at 1,5V 1600Mhz, and I want to add a little more voltage to the ram for stability. But in BIOS under the setting of Voltage for ram the setting is locked at "auto".
Which setting in BIOS must I change to unlock "DDR Ram Voltage" to raise it a bit?

Yes
Thank you very much

MSI Z77A-G43 - extreme memory profile problem

Hello everyone,
I’d really appreciate a piece of help here. I’ve bought the MSI motherboard MSI Z77A-G43 and currently I’m having problems with my memory (slots 1 and 3). My PC has following specs:
-   MSI Z77A-G43
-   Intel Core i5 2500K (not overclocked)
-   RAM Patriot 2x4GB DDR3 1600MHz CL9 (PGD38G1600ELK) G2 Series
Everything is set to default values and works fine. But when I enter the BIOS, I see that the memory is automatically set to 1333 MHz. The memory has the XPM. But when I set the XPM (agressive timing, 1600 MHz) support (no other changes) and reboot the PC, it doesn’t work (endless reboot looping). Is there any way how I can make the XPM modus work? The memory is OK (tried on other MBs, XPM without problems), the CPU too. I tried overclocking, with slightly increased voltage I can easily reach 4,8 GHz on CPU, basically everything else is fine. The PSU is also sufficient (700W, OCZ). I can too set the memory on 1600 MHz manually, but the timing isn’t that good.
It’s actually a failure I can live with, but since it’s a brand new PC, I’d like to get the best out of it.
Many thanks
V.K.

Sometimes manually setting them works when XMP refuses to.
I don't know what the XMP SPD profile for that memory is, and a screenshot of your SPD and memory tabs would help.
However try the following.
Disable XMP and reboot so they are back at 1333.
Manually set it to 1600 and ensure manual setting of the timings to 9.9.9.24 see if that works.
If not set your DRAM voltage to 1,575V and see if that works.
It may be that your memory requires 1,65V, in which case, that is what you have to set. You should be able to see that in CPU-Z SPD tab under the XMP profile column.

Z77A-G43 and latest bios, stable bios or beta bios?

I`m about to update my BIOS, Currently using ver 2.3, for my Z77A-G43, as official latest release on MSI website 2.8 version seems a bit outdated looking at BIOS versions released in here, what BIOS should I go with? Or would official 2.8 be the safest? Perhaps I would not go to the latest beta, I don't need that updated. I'm still on version 2.3 so I really need an update cuz lot's of fixes has been done.
I have been thinking ver E7758IMS.296 - it's second latest..
I don't need much CPU OC possibilities, I like to run it at stock + turbo, for 1 core, no PLL, no enhanced turbo, or what would be a good stock + turbo settings? I mainly need turbo for core 1 (and perhaps 2) as the game I play most is a 1-core game (well someone has said it a 1.5-core game).
SO what BIOS update should I get?
I'm mainly looking to squeeze some extra from my DDR3 (Kingston (KHX1600C9D3K2/8Gx) 2x4gb)). I'm going to try 1866, 2000?, 2133 and 2400 would be really nice! And going to squeeze some extra from GPU as well (Asus HD 7850 2GB) too.
Mainly looking for answer to BIOS here... But would be nice if someone would comment other too
EDIT: CPU = i5 3570K

Yes, I know about the RAM voltage issue, and will lock it to 1.5v.
Btw, I finally got BIOS flashed to 2.9!! M-Flash didn't recognize my USB stick, dunno why, last time when I flashed to 2.3 it worked fine. It just gave me message "Please plug in USB media and press enter to try again" - I tested every USB port.
So I used method found in this PDF article at MSI website "How to make a bootable flash disk and to flash BIOS".
I was also about to use the forum flash tool, but I've been suspecting it, has it ever failed? Broken a bios chip?
Right at the beginning I should of found out that XMP gives too much dramV to mems, and tweak it myself. XMP was giving dramV 1.65!! Should the XMP profile ( s ) to be updated for Ivy? XMP set my rams to 9-9-9-27 (CR: 1T) @ 1600mhz + 1.65V!! So I tweaked myself 9-9-9-24 (CR: 1T) and it's running fine with safe dramV.
I'm gonna keep the rams that way, I'm too tired to OC them now.. But time for GPU!

Z77A-G43 - DRAM banks 1&2 acting up.

Hey, guys. Thanks in advance for your time. I know it gets busy around here.
I am putting together a new system for the wife, and have an odd little issue. The DRAM banks 1 & 2 cause a pre-POST boot-loop when either are used. Banks 3&4 work perfectly. When a stick is in bank 1 or 2, the computer will power on, the fans spin, no video output, then it shuts itself down (regardless of what banks 3 & 4 hold). Repeats a few seconds later. All the usual trouble shooting has gone down. BIOS is all out-of-box default. All the components are brand new, but regardless were systematically replaced/removed one by one to narrow it down to these 2 ram banks. Needless to say, the RAM is fine - tested in two different computers. The memory banks are clean, new, with no visible dirt or damage. It's just odd.
Code: [Select]
1 2 3 4 <- Bank # ... X = used ... O = empty
X X X X = FAIL
X O O O = FAIL
O X O O = FAIL
X X O O = FAIL
O O X X = OK
O O X O = OK
O O O X = OK
The RAM in use is Kingston HyperX DDR3 1600MHz PC3 12800 4 GB (4 identical sticks = 16gb total) (KHX1600C9D3K2/8GX ). With RAM in memory banks 3 & 4, BIOS tones it down to 1333 from 1600, but that's the least of my worries. BIOS shows the timing as 9/9/9/24 and the voltage around 1.45 (can't remember exactly) even when it's increased to 1.65 (as suggested by the sticky). I also tried going 1 stick at a time but it started acting up as soon as I put anything in bank 3 or 4. There's just a lot of BIOS options that I simply don't know what they do.
I realize you guys have seen a lot of issues and was curious if you wouldn't mind lending a hand? I know my way around a computer, but certainly don't have the specialty knowledge particular to these pieces of hardware that you guys do. Any help is very appreciated. Please let me know if there's any information I can provide. I am dumping anything I think could be remotely relevant in this message. I really hope it's not a faulty board. Between disassembly and shipping, that would be an awful hassle.
Here's what I'm working with:
MSI Z77A-G43 (BIOS v2.2B2)
Kingston HyperX DDR3 1600MHz PC3 12800 4 GB (4 identical sticks = 16gb total) (KHX1600C9D3K2/8GX )
Intel Core i5-2500 3.3ghz
Nvidia GeForce GTX 550 Ti 2gb
PSU: Cooler Master GX 750W (RS750-ACAAE3-US)
A-Data 120 GB SATAIII Sandforce SSD (AS510S3-120GM-C)
Western Digital Caviar Green 2 TB HD (WD20EARX)
Case: Cooler Master HAF 922 (RC-922M-KKN1-GP)
No OS has been installed. I didn't want to get too involved until I knew the hardware was staying put.
Thank you again for your time.

I think the potential explanations for your problems are only a few. We can, I think, exclude a memory compatibility problem, since the sticks work fine in other slots.
In my oppinion, what we are looking at is one of the following things:
1. A problem with the memory controller (which is inside the processor) = defective CPU
2. A pin-contact problem between the CPU's contact pads and the board's socket pins causing certain memory slots to be improperly connected to the CPU's memory interface
3. A short-circuit problem, blocking the functionality of the memory slots (test the board outside the case on a non-conducting surface)
4. Defective memory slots or a problem in the underlying circuits = defective board
At your suggestion, I have made a couple of attempts to reseat the CPU (regarding #2). I realize that was a long shot, and not surprised to see no difference. I just wish I had another LGA 1155 CPU to swap out and test #1. I'm going to continue to brainstorm this for a few days before putting in a RMA request.

Hello i got a problem where my usb plug always stopped working for no reason
when i boot my PC , everything is fine and about 15-30 (sometimes more than 1 hour)
everything is stopped (Mouse , Keyboard , USB Microphone) BUT the Monitor and the Speaker works fine and it is still working
this is really annoying for me when i playing a game and my mouse got stuck and i have to restart my PC
and also i have an electricity problem in my house the voltage is unstable so i have to use stabilizer
is my motherboard affected by the electricity or what? idk i'm really really new at thing like this and do i need to change my PSU / Stabilizer
Thank you

Could you provide more details about the PSU? Wattage rating and the amp rating on the +12V rail(s). Also, what is the current BIOS version? Why 6GB RAM? Are you using 3 sticks? If so, that is known to be counterproductive and has shown performance hits in that configuration in benchtests. Use just 2 RAM sticks in dual channel placed in the proper DIMM slots.
PSU : 600W , +12v1 , 10.35A (Pic below if you want to see it clearly)
BIOS : American Megatrends Inc. V2.12, 11/1/2013
why 6GB? back then i could only buy 6gb because i don't have enough money lol
and i really really need it because it was urgent and i dont use 3 sticks only 2 sticks

MSI Z77A-G43 DRAM underclocking

hello guys, for some reason my DRAM on my MSI Z77A-G43 board underclocks itself.
i went into my bios and set it to run at 1600 mHz but when i use CPU-Z to check my actual DRAM speed it is only at 800 mHz.
so here is my questions, how does this happen and how can i fix it?
link for my current settings:

if not already done, update your bios to the latest.
then after that, go to bios, disable x.m.p., set (relating ram) everything auto, but select 1600 mhz for your ram, and then remember to LINK the timings if u have 2 or more ram sticks, now set the timings, 9-9-9-20 (or 22, or 24), and u should be fine.
x.m.p. is crap, 1) it feeds too much voltage 2) it sets the worst timings.

Z77a g43 boot issues

We'll start with specs
z77a-g43 motherboard
560 gforce video card
kingwin mach 1 psu
wd caviar black 1tb hdd
kingston 4gb ddr3 ram x2
razer mouse and keyboard
and then I don't remember the exact cpu but it's an i7 @ 3.4
I having issues with the system booting. Every so often when it gets turned off it would get hung up on an A2 error during post and a restart or two would fix the issue, but it is no longer doing the trick. Reading around a little bit I tried unplugging just about everything in an attempt to just get it to boot. Having just the cpu, psu, ram, and mobo going I get an A0 error. Plugging the hdd back in I get a B4 error and with the keyboard added in I get the A2 error. After removing and reinserting a stick of ram it actually booted to windows. I cannot recreate this though so I am thinking it was a fluke. I tried plugging the gpu back in to get an A2 error and then the mouse to get a B4 error.
I checked the cpu for signs of damage to see none, and I've flashed the cmos. When it hangs on one of these errors during post I can press tab and it will say that it is entering setup but then never does. I have never updated the bios so it is still sitting at the default.
I've read a few posts talking about various compatibilty issues that can arise with an un-updated bios, but it has been running fine for just around a year. This only happens from a cold start and is the worst case of the issue to date. Any advice would be appreciated.

With both sticks in I was getting A2 and with each individually plugged in I get the same error. Intermittently I will see the B4. Clearing cmos let's me into the bios, but if I haven't just cleared it, entering the bios just hangs forever. Bios is showing all 8 gigs of memory being read with system temps fine. Voltages all looked fine too. Attempting to save changes and reboot will leave me with a black screen. Discarding changes will get me to Windows. Also bios reminded me that my cpu is the i7-2600k if that helps.

Z77A-G43 Memory Timings Messed Up

I'm having trouble with the memory on my computer, and eventually after some searching, I found out that the timings are off (11-11-11-28 instead of 9-9-9-24). I don't know how to change the timings, and I've looked around on the internet for a while and I haven't found anything on manually setting the timings. The XMP is set to 9-9-9-24, but when I enable it and reboot, nothing has changed, and it still fails MemTest86. If someone could tell me how to change them, that would be great. Thanks.
Edit: Sorry, I completely forgot, here are the specs:

Try with just 1 stick of ram then the other, see if one stick is defective.
If you are able to enter bios, load optimzed defaults first.

and I'm sure there are more than 4 that are compatible?
There are, I usually just stick with Corsair or Mushkin because they have always worked for me.

Z77A-G43 drivers from MSI website not working

Hi, I've just built a new computer on a Z77A-G43, running Windows 7 Ultimate 64-bit.
Specs:
i5-3570K
8GBs of Corsair RAM
MSI 7850
120GB Intel 330 SSD - system
1TB WD Green - secondary
Instead of installing drivers from the supplied CD (except for ethernet drivers), I went to the MSI product page for my mobo for newer drivers. All goes well, except that I can't install the last driver I want - the Intel VGA driver for the GMA HD 4000 that's in my CPU. I read the readme, so I don't think I'm doing anything wrong. When I launch Setup.exe all I get is this error: "This computer does not meet the minimum requirements for installing the software." Running as admin doesn't change anything.
I'm thinking it must be the wrong driver. I looked through Intel's site, but would like to get a tested option here from MSI. I read some other forums of people having similar problems, some can't even boot after installing. I don't want to get into that situation. Could MSI please update the drivers page with the correct drivers? This driver isn't on the mobo CD anyway, so it's the only way to get it from you guys.
Btw, I also noticed the same problem with the Intel Rapid Start driver and I haven't tested the Intel Smart Connect driver. I'm not going to use either one of these, but it's worth noting.
Edit:
Found the VGA driver on the CD, but same result. Through the autorun MSI interface the VGA driver button in the Drivers menu is unclickable.

I finally got around to installing the VGA drivers for the GMA HD 4000. You don't even need to unplug your discrete card (PEG), in BIOS just switch to initiate IGP and make sure you have an HDMI/DVI/DSUB plugged in to the monitor and scanning for input. If you go to the Windows device manager, you'll see the system is detecting a new graphics adapter. You can proceed with the installation of the drivers as they will now detect the IGP. Then one restart and you're done. Btw, after restarting, if you have your discrete card connected and monitor also plugged in, the video input may fall back to it, so don't panic if you hear the Windows start up sound and see a black screen.
Unfortunately the G43 does not come with any support for Lucid Logix Virtu software, so that was my mistake, when I said I see it all in the BIOS earlier. In the BIOS, all you can do is switch between which graphics adapter you want to initiate and some memory size settings when multi-monitor is enabled in IGP mode. There aren't any d-Mode or i-Mode settings.
Btw, how can I mark this as solved?

MSI Z77A-G43-memory problem

Hello
I bought lately new cpu,mb and memory. When i turned it on it was still rebooting after few seconds after start. So i treid to put just one memory in slot. It worked but only if memory is in bank 3 or 4. In 1,2 computer is still rebooting. Also it works with two memory modules, but putted in 3,4 slots only. And just in single channel. I saw that many people have the same problem and shop service wrote them that it works like that. First You put memory in slots 3,4 and then in 1,2. It is strange for me. I don't have two another memory modules to check if this is true and I want to that it works in dual channel, not single. So, is this true or mb is broken?

Hello. I have the same problem, except, I use 4 Dimms in 4 slots on my MSI board. I installed speaker on MB to see if there are any beep sounds during the booting, but all seems ok. The problem is the PC keeps still rebooting after about 5 sec. from the start. There aren´t any visual information on screen, since the start is so short. I tried to install dimms in 2nd and 4th slot first. Then to 1st and 3rd. In both cases the problem was still the same. When I put all rams in all 4 slots, the result is the same (restart for ethernity). The only way that goes is the PC runs with only 1 dimm in either 1st or 2nd slot. I tested all the memory modules and all of them work fine. I even tried this on a differennt mainboard from ASUS P8Z77-V LX. Now I tested it on MSI Z77A-G43. Both mainboards are new. There is a very slim change that both of them would be defective. Before I got MSI MB, I ran couple of days on the ASUS MB and everything was perfect, so I don´t think that CPU is defective. I even ran a few benchmarks on it. But I still don´t understand why can´t I run the system with all 16 GB of RAM instead of 4 GB in one slot. Please help me.

MSI Z77A-G43 UEFI Overvolt+Intel Exteme Tuner Overvolt combo

Hey all,
I just wanted to run past you an experiment I did and I think worked.
I currently overclock my i5-3570k with an every day overclock of 4.4 at no offset voltage and a benchmark overclock of 4.7 at +.14V - however my benchmark overclock isnt exactly stable.
I noticed in Exteme Intel Tuning Utility There's a slider there for additional mV turbo voltage. I'm multiplier overclocking for my benchmark overclock with no power saving features and my voltage tops out at around 1.34V but when I add additional mV on Intel Extreme Tuner it goes to 1.38V. It also made me pass my 3dmark at 4.7 which is hit-or-miss but now worked every single time and also passed IBT.
Could this truly be modifying my input voltage on the CPU beyond the motherboard's limited offset mV overclocking?
Is this super dangerous and should I never do it again?

also obligatory 3dmark link

1.400v's on the CPU is the industry recommended limit for an everyday machine, so whatever way it gets there shouldn't make any difference.

If not doing a 'Turbo' OC, I don't see the connection with mV turbo setting. If raising the mV on the Intel utility raises the voltage to the CPU, and it is confirmed, then it must work as you have described.
