Msi z68a-g43(g3) sli

i read that it only has cfx support and not sli. i was wondering if there was a way to configure it to be able to use sli? perhaps a bios update of sorts. (im cheap and want to sli 2 gtx 550ti's)

SLI is not possible on this board. Nvidia doesn't allow SLI on boards not offering x8/x8 minimum for both slots used for the video cards. On Z68a-g43 (g3) it is X16/x4 so second slot is insufficient. The Nvidia driver does therefor not enable SLI and there is no way to enable it.

MSI Z68A-G43 (G3) motherboard

Can i put pcie x1 card to pcie x16 slot for msi Z68A-G43 (G3)?

PCI-E 16X33 slots are backward compatible with 1X devices, 'PROVIDED' the lanes are not all used up. In some cases, as a PCI-E 16X VGA for example is running at 16x, will be reduced to 8X when an add-in device is plugged into another available PCI-E 16X33 slot. Tests have proven a VGA running at 16X or 8X shows little to no significant performance loss.

MSI Z68a-g43 B2 post recomendation please

Hello,
as many others i also have B2 post problem after putting nvidia 650ti into PC
I realize its hybrid bios issue,and it requires updating bios to latest with GOP support.
BUT
There is a lot of complains about not being able to overclock intel 2500k after updating bios to 5.xx
As clearly my cpu is not Ivy ,but Sandy.And i need OC.
So,What is best solution here?
update to 5.2 bios and fix b2 post problem with eventual problem of not being able to overclock?
Does problem happens on all newer cards?Can OC be rectified?
Please Advise.
Thank you

Its G3
and i have chieftec 850W Nitro PSU
2xExcelleram Black Shark dual kit XMP there is no error on memory stress test of any kind
Now i am perfectly aware about what's causing the issue,and none of above is the cause
using E7750IMS.443 (clearly not 2.1 UEFI) so without GOP support mentioned below.
https://forum-en.msi.com/index.php?topic=155508.0
MSI Press Release info:
https://forum-en.msi.com/index.php?topic=162345.0
The NO POST (in fact, a hang on POST code B2) is caused by the Hybrid BIOS in the VGA card that has conflict/compatibility issue with older UEFI BIOS without GOP support.
GOP support has been introduced with UEFI 2.1 and is required by SecureBoot, thus Win8 compliance (not required by end users).
Now back to original question..
I also readed that people are heaving problems with OC-ing 2500k after updating to 5.2 bios.I cannot let that happen.
I will rather return gpu and choose another one if there are some range which are not affected.
because MSI states its for 660-670 x cards
While clearly i am trying to use 650 card
and other have had same problem with 780 nvidia..
So ..what to do?
How to choose gpu ,OR avoid problem with OC with 5.2 bios?
Board has no problems with older gpu's tested with 560ti and ati 4870
EDIT
I run into discussion about same OC issue with 5.2 bios
https://forum-en.msi.com/index.php?topic=167075.0
It seems that there is no definitive answer...
Trial and error ..
I cannot accept that,i need OC and i need working gpu..
upgrade to ivy is not an option...
what to do..

Z68A-G43(G3) boot failure message

I have an i7-2700K Sandybridge processor on a Z68A-G43(G3) motherboard with BIOS v 4.3. I am now having boot up error messages: "Warning!!! The previous overclocking had failed. Please enter Setup to configure your system."
I am not overclocking. I tried clearing CMOS and loading default values into the BIOS and it worked perfectly for a while, but the warning message is appearing again.
I have tested my RAM (8Gb) and it checks out OK and updated my PSU.
Any suggestions please? I see that there's a BIOS update to v 5 but that is for an Ivybridge processor while mine is Sandybridge.

I have been having a similar problem with my parts below:

So I have built 4 pcs, all with the above specs. All the motherboards serial numbers are sequential, meaning from the same production run. 3 of the 4 are set up the same, with raid 1 on the hard drives.
On 3 of the four PCs, off random boots (usually after being on for 2 days), a message will pop up in the startup, pre-bios, that says:
Overclocking has failed. Press F1 to boot, F2 to enter Bios setup.
They aren't overclocked. I measured the peak wattage and it hovers around the 200 range, well within the 550 power supply.
What I've done so far:
Updated Bios to newest revisions.
Contacted manufacturer. They said check the memory. Ran memtest86 for hours. No problems.
Also purchased new UPS backup with Voltage monitoring, etc.
RMA-ed two of the boards with the replacements having the same problem.
I've just stumbled onto this thread here: https://forum-en.msi.com/index.php?topic=159053.0
To try it, I've changed the DRAM Frequency from Auto to DDR3-1600MHz. This is where I currently am. Curious that it happens to the machines that are set up in raid 1, but not the non-raid machine.

Z68A-G43 (G3) Crossfire

Im having a problem..
Im running at Crossfire setup, and GPU-Z and HWiNFO64 reports that 1st GPU, connected to PCI-E 3.0 x16 port, runs at PCI-E 1.1 x16 and 2nd GPU, connected to PCI-E 2.0 x16 port, runs at PCI-E 1.1 x4..
Cant get them to work at PCI-e 2.0 at any settings, as i have understood that this MB should be able to run 1st GPU at 2.0 x16 and 2nd GPU at 2.0 x4..
Everything else works like a charm, but that PCI-e mode problem was there before i flashed my HD6850 with HD6870 Bios, so that didnt affect it.
Both GPUs support PCI-E 2.0 x16!
OS: Win 7 Ultimate 64bit
Case: BitFenix Merc Alpha
MB: MSI Z68A-G43 (G3) BIOS upgraded to 5.2
CPU: Intel 2500K 3.3GHz OC to 4.5GHz
CPU cooler: Antec H2O 620 with Arctic Silver 5 paste
CPU Fans: SilenX Effizio Blue Led x2 as push/pull
GPU: Sapphire HD6870 1Gb CF with HD6850 OC 900/1050 by flashing with 6870 bios
RAM: Corsair DDR3-1333 unbuffered 4*4Gb=16Gb
PSU: Corsair GS800 800W
HDD: Corsair Force GT 120Gb SSD Sata3 HDD as primary, Samsung Sata2 500Gb as storage + USB3.0 500Gb HDD as 2nd storage
If someone knows why its on 1.1 and not on 2.0 and knows how to fix it, i wish you could share ur info.

In GPUz look when they are under a load.
Many boards will "clock down" the PCIe lanes when the extra bandwidth is not required. For instance running a benchmark they will be at 3.0 then drop to 2.0 or something at idle. In your case, 2.0 being the max, it wouldn't surprise me if they or the slave card alone dropped to 1.0 at idle.
If your after a little more reading...not a huge difference between the 3 iterations of PCIe.

Does the MSI Z68-G43 G3 support 8/8 PCIe 2.0 lanes (for SLI/CF)

Hello,
The MSI webpage states
Quote
• 1 PCI Express gen3 x16 slot, 1 PCI Express gen2 x16 slot
• 2 PCI Express gen2 x1 slots
• 3 PCI slots, support 3.3V/ 5V PCI bus Interface
for the MSI Z68-G43 G3. It doesn't say whether the board can run the 16 PCIE 2.0 Lanes in 8/8 configuration. My current (Gigabyte P67A-D3-B3) board can only do 16/4, so I am considerung moving to this board for Crossfire. Does anyone know if 8/8 2.0 is possible with this board and a Sandy Bridge CPU?
Regards
chris

Quote from: RemusM on 27-September-14, 04:52:45
SLI is not possible on this board.
The PCI-E 2.0 slot is equipped with only 4 lanes.
http://www.msi.com/product/mb/Z68AG43_G3.html#hero-specification
PCI-E Gen : Gen3 (1x16), Gen2 (1x4)
Thanks for the help, Remus!
I am now looking to get a Z77A-GD55 instead. It is specified as PCI-E Gen : Gen3 (16, 16), Gen2(4) so it should be fine (Sandy Bridge only reduces it to Gen2 (16, 16) instead of Gen3 (16, 16), right?).
They are somewhat hard to find, though, unlike the Z68A-GD65-G3 with Gen3 (16/0, 8/8) and Z68A-GD80-G3 with Gen3 (16/0, 8/8), Gen2 (1x4) . So I'll see what I can get.

PCIE 3.0 test with MSI Z68A-GD80 G3 :)

The Z68A-GD80 G3 is MSI’s first motherboard with PCIE 3.0 connectivity. Currently there are no PCIE 3 devices available yet but later on we can test its performance by using a PCIE SSD. Aside from this, the board has also a new UEFI Bios named “Click Bios II” which for me is way better than the previous version.
Before we take a closer look on the board, let’s check out the package first.
Box design is a bit the same as the GD80 B3 version before. Once you open it up, all main features of the said board are enumerated
Extreme Power Design, Military Class II Components (SFC, Hi-C Caps, Multi Bios), 3 PCIEx16 Slots, Super Charger and OC Genie II
For the bundled accessories, you have the same old story – Manual, Software Disc, four SATA cables, two Molex to SATA power connectors & SLI Bridge. Then for some extras - PCI USB 3.0 two ports bracket, guide headers for faster and easy connectivity and lastly voltage check points.
Next, the “Mainboard”. By physically looking at it and by comparing it side by side against the Z68A-GD80 B3 motherboard. You won’t find any difference except for the PCIE X16 locks. It has also the same black and blue color theme, two vrm heatsinks connected by a flat heatpipe and V-Check points.
Moving closer to the board you have 8 Power Pins to power up the processor, 2 PCI slots, 2 PCIE x1 slots for devices such as TV Tuners or Audio Cards. 2 PCIE Gen3 & 1 PCIE Gen2 x16 Slots. With one VC connected at the top most slot, speed will be @ x16. If both top and middle are used, it will be @ x8/x8. Lastly, by using the 3rd PCIEx16 Gen2 slot. You have x8/x8/x4. It would also disable certain onboard devices such as eSATA Port, Sata 7, one onboard front USB 3.0, two PCI Slots and firewire. So if possible avoid using the last VC slot.
At the top most PCIE x1 area. You will find a 6-pin power connector. This will provide more juice/power for multi-GPU setups.
Next, at the bottom part of the board. You have the Easy Buttons (Power and Reset) and the popular one button “OC Genie”. The red colored USB header is for the Super Charger while the blue is a regular USB 3.0. For the SATA Connectors you have a total of 7. 4 regular SATA 3GB/s, 2 SATA 6GB/s controlled by Intel chipset and another SATA 6GB/s by Marvell.
Wrapping things up, we have now the IO terminal ports. Starting from the left we have combo PS2 port and SPDIF Optical Out. Clear CMOS Button, e-SATA port running under Marvell, 2 USB 2.0 and Firewire ports controlled by Via. Moving across, 2 Gigabit Lan by Realtek 8111E, 2 USB 2.0 and 2 USB 3.0 run under NEC D720200 controller. Next, we have DVI and HDMI output connections and 6 analog audio ports by Realtek ALC892.
Once you are into the bios, you will find the new and improved Click Bios. Nice and professional looking, faster navigation and easier to use.
To test the performance of the new PCIE Gen3 technology, we will be using this Photofast PCIE SSD device http://www.photofast.tw/comboproducts.asp?pid=1.
We will be connecting the PCIE SSD device on the GD80’s Gen3 and Gen2 slots and compare the results using the disk benchmark software ATTO. I ran the benchmark 9 times for the two set of tests.
System Configuration as follows:
Processor: Intel Core i7 2600K at default stock speed
Memory: Kingston HyperX Genesis Grey 2x2GB DDR3 2133MHz
SSD: OCZ Vertex 2
Motherboard: MSI Z68A-GD80 G3
Softwares: CPU-Z 1.58, Windows 7 Ultimate 64 Bit with SP1, Latest Atto Software 1.47 I think.
First test, Photofast running on Gen2 (third VC slot). One screenshot from the 9 tests made
Second, using the Gen 3 connectivity. One screenshot from the 9 tests made
Below is the summary of all the tests done on the board with the Photofast SSD PCIE.
That’s probably it. More forum posts to come 

Did you have your previous board's BIOS set to AHCI or IDE ? You need to set this BIOS the same.
Firstly only insert one RAM module in the slot closest to the CPU. Remove the rest. Then do full CMOS clear >>Clear CMOS Guide<< also remove the MB battery.
What BIOS do you currently have ? The initial BIOS releases were plagued by CPU throttling which have been fixed in the cyrrent beta BIOS releases.

Z68A-GD65-G3 SLI black screen lock ups

Let me start off by saying I have tried everything and I motivate everyone to prove me wrong and provide me with a solution to this issue.
System spex:
MSI z68A GD65 G3
2600k
Corsair XMS3 1600 16GB
Corsair AX1200
2 - EVGA GTX 580 3GB SLI
Running beta bios: E7681IMS.N49 from -> https://forum-en.msi.com/index.php?topic=151148.msg1144560#msg1144560
I have tried almost every BIOS under the sun, including "standard bios" ie flash back to factory BIOS
So here is the issue:
In order to run SLi I have to be at completely stock settings, if I even up the multiplier to x35 on my CPU I black screen as soon as I bench/game on the cards. If I bench only the CPU (prime95) it is fine and no issues. but again as soon as I loud up something graphics wise the screen goes black and locks up.
It isn't the cards either, each card has been tested on its own and in different PCs in SLi.
It is like the motherboard cant handle the power??????
Someone else has to be overclocking and running two power house cards like this without issues? right? what did they do different? what settings? am I missing something?
Or do I need to contact MSI and get a RMA in process.
Before adding the extra card I had my CPU @ 4.7Ghz and when I would bench it I would take it to 5Ghz+ without a issue... solid, never had a BSOD. but this extra card just kills the systems.
Again everything set to stock and the system runs great I can game on it for hours without issues.
Thanks
Nick

Quote from: Bernhard on 30-December-11, 00:22:38
I am not running your PSU down, don't get me wrong. You have the best PSU by general consensus. All I am suggesting is to check it in another system under similar OC conditions with approx the same specs.
It does fine with SLI non OC, yet when you add the extra load of OC, and that can be an additonal 50 to 100W, then the PC becomes problematic.
It could be something else, but one has to start eliminating potential culprits.
Edit: Did you install Virtu ? If so, have you tried deleting it again for a test ?
Oh I understand completely and thank you for your suggestion and time, it helps me to believe that it could be my PSU even more, I am borrowing a PSU from a friend and a PSU tester from work and tonight will get a chance to do some full testing on the PSU.
If that tests out ok I will pull my PSU out and RMA it. hopefully Corsair will have a quick turn around.
Virtu isn't installed, I will double check but it was disabled in BIOS, but i have reset my BIOS so many times I will make sure it still is.
I will report back with my findings.

Z68A-G43 No Core Voltage setting?

Hi all
Well my mobo was crashing all the time with my Q6600 @ 3.4ghz so I went ahead and got a Z68A-G43, i5 2500k and 8gb of 1600mhz G-Skill Ripjawx ram.
I've noticed though....the BIOS has no setting to change core voltage, neither does MSI Control Centre or Click Bios in Windows. So...does this board have no setting for to change it I ask? I mean it may be low down in the range but £75 is a bit tall for budget board is it not? I've got a rock solid 4.5ghz overclock..I can't boot into Windows with 4.6ghz but if I use control centre I can get it solid in Windows at 4.6ghz @ an auto voltage of 1.386v (I mean I've literally thrown everything at it and its not choked).
It would be nice to try and push for 4.7ghz if I could just give it a bit of Vcore myself! Cheers

Quote

A solid OC of 4,5GHz on the budget Z68 offering ? Mere mortals would be over the moon to boast with such an OC, what is it, 30% ? It's always that tiny bit extra we all want, and when we have it, sometimes we don't know what to do with it.
Most of us run our boards around that OC to maintain the full power saving feature. Sandy Bridge has this unwanted side effect, whenever you manually set the VCore, it will remain there, no matter what, even in idle.
But you are welcome to check with MSI technical if it's even possible to introduce this via a BIOS change in the future. I doubt it. >>How to contact MSI.<<
Believe me, the 2500K above 4,6GHz generates mostly heat and the gain in performance becomes insignificant.

Z68A-G43 2500K throttling

Having the same problem that a lot of users seems to experience with this board. MY 2500K at a 4.5GHz overclock keeps throttling down to 4.3GHz when under heavy load, such as Prime95. I'm running the 4.1 BIOS version but have heard of the beta version of 4.2 fixing this issue?

The latest BETA UEFI Release for the G3 version of the Z68A-G43 should fix the ratio drop issue:
