MSI Big Bang-XPower II SLI question

Hello. I have a MSI Big Bang-XPower II with two cards in SLI. The cards are cooled using AIO water cooling brackets which makes them take up three slots each instead of two. I would like to add a third card with the same cooling. The manual says that for 3-way sli I should use slots 1,3 and 5 or 7 as they are all PCIe 3. My processor doesn't do PCIe 3 so I leave it in PCIe 2 mode. My question is, could I set up the SLI configuration using slots 1, 4 and 7? Would it run at 16/8/8 in pcie 2? Or would the 4th slot not be usable for sli?
Thanks

No, that is not possible. PCI_E4 is a gen2 slot limited to x4. SLI is disabled once a slot used is at less than 8 lanes. Follow the Multi GPU support table on 1-21 of your manual.

MSI Big Bang Xpower II SLI slowness

Hello.
I just purchased the big bang xpower ii to change from Asus RIVE.
Had trouble with bios 2.5 (no sound) and reverted to 2.4.
In both bios, using a 4930k and a SLI of 780ti, I am seeing slowness in certain games like Crysis 3 in some scenes. In these scenes (for example in Crysis 3 where there are open fields or grass moving), the performance in sli is similar to use only one card...
This slowness was not in other x79 motherboards, like Asrock x79 Champion or Asus RIVE (I had both of them). I tried modifying latency in bios, but got worst as I had previously the shortest 32... I have gen3 activated too...
Anyone seeing slowness in sli using a 4930k???
Thanks in advance..

Don't expect amazing results for SLI configs in ANY condition.
I didn't perform all the GTX 7xx SLI benchmarks, but the results are similar with the GTX 6xx ones.
There is a 50% performances boost, but that's for rendering only!
In a complex 3D games (such as Crysis 3) there are many other things involved.
"Grass moving" and "open fields" are processor killer tasks.
Also, the CPU is performing all the physics tasks.
To conclude: in a complex 3D application, the CPU is responsible for 40-50% of the FPS value.
In other words, "Core i7 + GTX 650" gives better FPS value than "Celeron + GTX 780".
However, your config (i7 4930K + 2 x GTX780) should be more than enough for any current 3D game.
If you have "unexpected" FPS drops, double check the OS/drivers and the PSU.
With a messed up OS and/or a weak PSU don't expect great performances.

MSI Big Bang-XPower New Build Compatibility Questons

I am doing my first build, and do not see several components I have selected (some already purchased) for my new system in the MSI compatibility literature for the Motherboard. Can someone please advise if any of the below components will cause issues? I have done much research and believe I am OK, but would like to have confirmation before proceeding. As an FYI, I will be doing video editing with the new system:
1.) Motherboard: MSI Big Bang-XPower LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX Intel Motherboard (purchased)
2.) Video Card: MSI N470GTX Twin Frozr II GeForce GTX 470 (Fermi) 1280MB 320-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card (purchased)
3.) OS Drive: Western Digital VelociRaptor WD6000HLHX 600GB 10000 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive (purchased)
(I will also have four 1TB drives in raid "10" - 7200 RPM Western Digital SATA 3.0 Gb/s for data storage, working files, etc.) (to be purchased)
4.) CPU: Intel Core i7-950 Bloomfield 3.06GHz LGA 1366 130W Quad-Core Processor BX80601950 (purchased)
5.) Memory: This one I would like confirmation on but I believe it will work (I like that it is Cas Latency 7 and know I will pay a few more $ for this):
G.SKILL Trident+ Turbulence II 12GB (3 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL7T-12GBTDD
DDR3 1600 (PC3 12800) Timing 7-8-7-24 Cas Latency 7
Voltage: 1.65V
Multi-channel Kit: Triple Channel Kit
Timing: 7-8-7-24
Model #: F3-12800CL7T-12GBTDD
Item #: N82E16820231381
6.) OS: Windows 7 Ultimate (purchased)
7.) The other items are fairly straight forward.
Any feedback on the above will be greatly appreciated, especially the memory.

I have two follow-up items from the above (one power supply and one RAM):
1.) I Am between the following 2 power supplies:
- CORSAIR HX Series CMPSU-850HX 850W ATX12V 2.3 / EPS12V 2.91 80 PLUS SILVER Certified Modular Active PFC Power Supply ($169.99)
- CORSAIR Professional Series AX850 850W ATX12V v2.31 / EPS12V v2.92 80 PLUS GOLD Certified Modular Active PFC Power Supply ($194.99)
I am leaning toward the first one, I do not believe the second is worth $25 more - comments???
2.) I spent another few hours on RAM selection today. This is driving my crazy...
I spent time today with Intel concerning RAM for the Intel Core i7-950 Bloomfield - here is a cc of my log (they obviously have only one recommendation):
You are now chatting with 'Allan'
Allan: Hello. Thank you for using the Intel Customer Support chat service. We are glad to be of service. How can I help you today?
sldwaa: I just purchased in i7-950 Bloomfield and am in the process of purchasing the RAM. I have an MSI Big Bang X-Power MOBO and am running Windows 7 ultimate 64 bit. I have read many posts and Intel spec sheets and I understand Intel does not recommend anything other than 1066 / 1.5v VDIMM. Now for my question as I am new to purchasing ram and building PCs. Here are my questions:
1.) I am deciding between 1066 and 1600. The most posts recommend 1600. The obvious alternative is the Intel recommended 1066. I believe if I do not over clock, 1066 will be the ticket. If I buy the 1600, then I can only achieve this by over clocking - correct?
2.) If I buy 1600 and do not over clock, it will perform at 1066 without any negative effects - is this correct? This is assuming XMP is not enabled. I will not be a heavy over clocker, but want the capability just in case.
Allan: the processor supports DDR3-800/1066 at 1.5V
Allan: no other memory is supported... no matter if the board supports 1600 or even 2000mhz
Allan: I remind you that the memory controller is on the processor, this is not integrated on the board
sldwaa: Understood. Follow up question - If I purchase 1066 with the fastest CAS Latency I can find (possibly 7), can I over clock the 1066 (understanding the negative potential effects) or would I still need the 1600 to achieve any over clocking capability?
Allan: I am afraid I cannot answer that... I cannot comment anything about over clocking
Allan: you will need to search this information on Internet
sldwaa: OK - to summarize you only recommend 1066 at 1.5VDIMM. Anything else, I am on my own, including risks of overheating and instability = correct?
Allan: that is exactly correct
Allan: Intel recommends DDR3-800/1066 at 1.5V
That being said, I guess I am between 1066 with the lowest CAS Letency I can find at 3x4GB, or go with the 1600 (I researched and agree 3x4GB is better than 6x2GB). As intel is against the second, based on what I am reading, I am leaning toward 1066. If so, can I overclock the 1066 to something higher or is this the max speed? Help!

MSI Big Bang-XPower, Corsair AX1200W and 6-pin motherboard connector

Hello, I apologize if this has been answered but I didn't seem to find it on the forums. I have the Corsair AX1200 power supply and the MSI Big Bang-XPower motherboard. The board has two ATX 8-pin connectors. I know that the second one is only needed if you are doing serious overcloking. But I assume it's ok to plug both in whether or not I'm overclocking?? I see the AX1200 has two EPS/ATX 8-4 pin connectors so I am fine there.
My real question is that the mother board also has an ATX 6-pin connector for the graphics card. Firstly, is this needed since the graphics card has it's own power connector (I have the EVGA SuperClocked 015-P3-1582-AR GeForce GTX 580). The card needs a PCI-E 6 pin and an 8 pin connector. I see the AX1200 has six 6+2 pin connectors so I believe I'm fine there.
But for the motherboard connector, can i use one of the PCE-E 6+2 pin connectors (just 6 pins obviously), or is this not good sine the connector is not labeled as an ATX connector?
Thank you.

Hi,
Bumping this as it is the question I have. How does the motherboard access this power from the EPS? It is constantly available to the cpu? Would it not be better to plug in the 2x8 pin EPS anyway as it gives a greater redundancy?
I am sorry if this is a stupid question but I recently got flamed on a forum for carrying on about connecting the EPS cables up to my Corsair Ax850. The flamers carried on and on about how I would never need to use the EPS unless it was LN2 cooling.
I cannot see the harm in it but I would like to understand computer power supplies a bit more and how exactly they work. For example why do some vid cards have 6 pin and other 8 pin when it looks as if both plugs just have a 12 volt lead on one row and the other row a ground lead?
Anyhoo.
Happy first post to me.

MSI Big Bang XPower II X79 release date

Whats the release date for this motherboard to the UNITED STATES?
MSI Big Bang XPower II X79 LGA 2011

We don't know, we have nothing to do with MSI marketing. We are MSI product users the same as you helping each other with problems and have nothing to do directly with MSI. You would need to ask MSI. Question like that my typical answer is that you will know the release date after you see it for sale in the stores.

As a matter of fact if we knew the release dates of products like that we would post it in the forum to avoid those kind of questions all of the time.

MSI Big Bang-XPower quesiton on connectors

I have the MSI Big Bang-XPower and have a few questions that I couldn't answer by looking in the manual or searching the internet.
1. What is the TPM connector/module exactly used for?
2. What is the jspI1 connector for? It's not listed in the manual.
3. The JFP1 cnonector has 2 pins for POWER LED and the JFP2 connector has 1 pin labeled POWER LED. Should the case power LED be hooked to JFP1? What is the POWER LED on JFP2 for?
Thank you very much.

Google still works. TPM: http://en.wikipedia.org/wiki/Trusted_Platform_Module
JSPI1: http://www.google.com/search?q=jspi1&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a
JFP1/JFP2: You would connect power LED to JFP1 if LED doesn't light up connected one way just reverse the wires and it will work, nothing will be damaged no matter which way they are connected. I'm not sure anymore what it's for on JFP2 except that some cases have different plugs for such things.

MSI Big Bang-XPower powers off then powers on to boot to OS

Not sure if this issue has been addressed on the forum yet. I purchased a new MSI Big Bang-XPower motherboard this past week ,with Intel Core i7-990X as the cpu. I'm using SILVERSTONE SST-ST1200-G Evolution 1200W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS GOLD as the power supply and Kingston HyperX 12GB (3 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) for memory. This is in a Lian Li X-1000 chassis.
I built the system completely and loaded the OS (win7). I noticed during the updates, when the system would need to reboot. The system powers down, then it would power back up, then power would cut off and the system would restart and load right to the OS. I finished the updates and loaded other needed software. This problem continued during the whole time, when ever I needed to reboot. I was even able to load my games and played one. No over clocking needed.
I started my trouble shooting process,
flashed the bios from v1.4 to v1.6 - no changed
changed the bios settings to boot something(can't remember) default - no change
So I started eliminating anything connected to the motherboard. - no change
I'm down to the motherboard, cpu, ps and one 4gb stick of memory - no change
It did not matter if the system was cold or hot, still the same problem. The mb LED would go to A1 every time and almost start running again before it shut down on it's own. Powers back up and boots to the OS.
I'm at a stand still, on what's causing this problem. I'm sure it's not the memory, because I have pulled this memory from a working system and no problems. Plus, if is compatible with this MSI board. So either it's a bad mb, cpu or ps. All three of these parts are brand new and I still can return them for exchange.
Anyone have any ideas or suggestions ?

In BIOS Power Management, or Green Power, I forget which, disable EuP 2013, that should cure it. If it doesn't cure it, it has been a known odd behavior trait of Intel systems for years. Also, disable Spread Spectrum in the Cell Menu.
Anytime a setting has been changed, driver update reboots etc., it is not uncommon to also experience the double boot behavior. This is normal as the settings are being applied & restarting itself again.
I've seen this behavior before in the factory with Intel systems. The dual boot behavior usually was a component failure. Which I suspected and turned out to be my problem with this MSI MB. I tried disabling EuP 2013 and spread spectrum, which did not fix the problem for me. Contacting MSI tech support on the phone, was irritating and sub-par but I was finally able to RMA the MB through the online request . Since receiving the new MB and installation. No problems with the board and actually have clocked the chit outta of the board. Thanks for your reply and help.

MSI big bang xpower ii memory problems

Hello! I wasn't sure where to post this question, so If it is in a wrong subforum please forgive and transfer it to the correct one.
Story is, I have msi big bang xpower ii motherboard, runnig 3930k, c1 cpu. I have two memory sets, both tested extensively, 1) gskill ripjaws 2133 32gb 4x8 (one matched set), 9/11/10/28 1.65v and 2) gskill ripjaws 1600 16gb 4x4gb 9/9/9/24 1.5v, also one matched set.
I updated bios to 1.2 (i think that's the latest official one).
Problem is, in 2133 mode, i can only post with 1 stick. With set 1) in 1600 mode I can post with 2 sticks (any slots as shown in manual). With set 2) in 1600 mode, I an post with 3 sticks (also any slots as shown in manual). That's it. Any other configuration (for example quad channel or 8 sticks) will not post, I get error 67.
I tried manual mode as well as XMP. It seems in XMP mode i don't even get to error 67, it just keeps rebooting and rebooting, rebooting on error code 19.
Does anyone run this 2133 set at 4x4gb ? If so could you please possibly give me your OC settings? I tweaked vccsa, pll and dram voltage, but no luck.
Thanks in advance.

It won't boot in quad channel even in 1333. Manual says, if you number slots A B C D | E F G H, quad channel is A _ C _ | _ F _ H . It will not post in this configuration. Neither of my two sets (even 2133 running in 1600 or 1333). However, A B C D | _ _ _ _ will post in 1600! I tried this out of curiosity and this is technically an invalid configuration? It's not even mentioned in the manual. It also seems to me the system will never post if I have something in slot G.
I also must add both of my kits are tested, additionally my asus rive can run quad set in 2133 just fine.
I set 1.5v kit at 1.5, then tried 1.520. For 1.65v kit, i tried 1.5, 1.520 and 1.65 and next one I don't remember i think 1.68. I tried vccsa (system agent) 1.15 - 1.30, also, why is PLL so high on this board? I am seeing ~ 1.77 (I did set it at 1.8 later).
Also what are the modes 1-7? Where can I find more information about those?
Should I RMA this board? I can probably get it replaced within a day or two.
I also must note, I have the worst luck ever with lga 2011 boards. It took me 3 tries to get normal rive, and now this. Sigh.

MSI BIG BANG Xpower II boot issue - LED code 9A

Hello all,
I am facing to issue after BIOS update from 2.6 to 2.7. After update was machine working properly. But after one crash of OS cant boot at all. Crash was probably caused by overloading GPUs but there were no issue with cards and this board during 3 weeks of 100% GPU and CPU load. No video (connected only one GPU card), no Numlock key/led is working (this is good test if PC is reacting even no picture).
Board: MSI BIG BANG XPOWER II
Bios: Version 2.7
VGA: 4x AMD SAPPHIRE Radeon R9 290x
PSU: Silverstone 1500W (gold)
CPU: Intel Core i7-4930K 3.4GHz (3.9GHz Turbo Boost) LGA 2011
MEM: 1x Kingston 8GB DDR3 1600MHz CL10 HyperX blu Edition
HDD: WD Blue 256gb 5400
COOLER: NOCTUA NH-D14
OC: 3.9GHz
OS: Windows 8.1 64bit Professional
Tried
- switch BIOS from A to B also C (with small switch).
- cleared Cmos with onboard button.
- removed Battery for a while
System start booting and stuck always on 9a LED code.
From manual it looks like it is USB, SATA initialisation phase.
I think CPU or Mem should be fine.
Anyone who met this issue or any sollution?
I am thinking to replace this board under warranty.
Thanks for any info..

Hi Froggy,
Thanks for reply.
But I have tried disconnected all USB devices and got same LED code. If this happend because of some USB configuration in BIOS why reset of CMOS did not help?
It very well could be setting(s) in the BIOS, but I am not qualified to be of much assistance when Win 8/8.1 is involved.

MSI Big Bang xPower II PCI-e 3.0 Problem

Hey Guys
I´ve got a big problem with my Big Bang Xpower II Mainboard. Although i´ve got at PCI-e compatible (Gigabybte GTX760 OC) which is placed in PCI-e Slot 1 and PCI-e Gen 3 activated my Board doesn´t activate PCI-e 3. I´ve already tried to install the UEFI on several ways but nothing helped.
My specs:
Mainboard: MSI Big Bang xPower II
CPU: Intel I7 4820k

Soundcard: Creative Soundblaster Z
RAM: Crucial Ballistix Tactical 16GB 1866MHz
sry if there are Mistakes my english is not so good because im from Germany and and im still a student
thanks for your help

Aha, but how windows changes will affect BIOS PCI-e version reading?
etc: this one which you said:

You can see the PCI-e Version activated before the Xpower BIOS Screen shows off (the where it show all data about the ASMedai chip ...
or this still shows 2.0 during bios post screen?

MSI Big Bang XPower II - Corsair H60 Water cooling issue

So I am using a Corsair H60 water cooling on my MSI Big Bang XPower II mainboard. I have followed the correct instructions on installation but every time I turn the computer on once it its 31 it shuts down. Everything seems to be working correctly except the cooling. There are no instructions that really relate well to installation for this water cooling to this mother board so I have tried placing the pump power and the fan power on various different inputs. I have the pump just on a sys power fan and the 120mm fan blowing through the coils on the back of the machine connected to the CPU 1 head fan (as instructed in their videos). I am not 100% sure the pump is working but I know that the fan is working and the hardware overview shows it recognizes the fan.
anyone have some ideas to try to see if I can get this to work? I am also wondering if it is a faulty pump or something but it seems to be working.

Quote from: seth.eckert
I have the pump just on a sys power fan
The pump is not working. The 3-pin connector for a fan header is just for reading out pump speed. You need to power it with the molex connector.

MSI Big Bang XPower II - Firewire and PCI issues

Hi all,
yesterday i recieved my new MSI Big Bang XPower II and got some really strange issues:
First of all ill let you know my hardware:
MSI Big Bang XPower II (BIOS v1.4) new
Intel I7 Extreme 3960X new
G.SKILL 64GB RAM Kit 1600 new
Palit NVIDIA GTX 680 - 4096 near new
3 x RME Soundcards used but okay
7 x WD 2TB SATA where 3 are OS Systems and 4 are Storage used but okay
Be Quiet Dark Power 1200W new
1 Problem:
There is absolutely no Firewire available. I tested the onboard connection (which is at the backplate) and i also tested the extension connection with a additional firewire slot. Also it seems that wether Windows nor Linux is recognizing the firewire at all. The strange thing is that i recieved this new board after i send the first one back to my reseller with exactly the same problem!!! I also take a look into the BIOS if there is any option i need to activate but as far as i see there is nothing to set for 1394?
2 Problem:
As you can read above i use my GTX680 and all 3 RME Soundcards each with one PCI Slot. But some of the slots are not working fine. If i, for example mount my GTX680 to Slot 1 and want to mount my first RME Souncard to slot 4 (2 and 3 are covered under my GTX680) its not working. If i try it in slot 6 for example, the soundcard works fine.
BUT:
The slot 4 is not damaged cause if i set my GTX680 to slot 8 and retry my RME Cards in slot 4 its working...
Never had that before!
I connected the 24pin ATX and both 8pin connectors (the 4pin additional connector for the graphics is not used).
Would be nice if someone guiding me through the dark

With so many components and shared resources, you are gambling with IORQs and I/O addressing space.
Mmmhmm i dont thought about getting interrupts, MSI is offering the board with that configration/features and if there is one user out who try to use the board near to the fullest it should of course work or not?!

I read some comments and i see this MOBO don't support my Processor on the original version of the BIOS crap I have I7 4820K ;/
I bought new chip with the newest Version of the BIOS i swap it with the CHIP Original installed I Clear the CMOS and press multi BIOS button then i plug in my PSU
NOTHING monitor is still on stand by i check with 3 Video cards all are working with my sec PC no issues
i don't know what to do that's sec MOBO first one was faulty and after switching it on one of the chips just spark MSI swap it for new one and that one is not working to :(
any ideas someone know what i do wrong ?
the Chip i buy with the BIOS can be faulty to but how i can check it i guess I cant ;/
then how i can flash BIOS when i even cant get the MOBO boot ? and i will not buy older CPU to start the MOBO that will be just insane and i don't have any one who can barrow me one for 5 min ;/

HELLO
Again ME I think its a warning for a lot of you
Finely MSI contacted me and i get my RAM nr I spend 40£ to send the motherboard to MSI in Netherland yee i was happy someone will deal with the problem I have and they will update my BIOS to make sure my CPU will be compatible with the Mobo.
Today I receive my MOBO back I was really happy i connect all and i get in SHock nothing the same issue no Video output Monitor stays black just like was before the debug panel is off nothing running
i check and the serial nr of the MOBO is different what mean its total new Mobo and probably coz i cant get it running its same old BIOS i spend 40£ probably to swap new Motherboard for New Motherboard but not to fix the issue and the issue was simple i need version of bios 2.3 or higher to make it work with my CPU I7-4820K
now I don't know what to do the shop where I buy the Mobo dont want to help me and when i ask for my money back they seid its after the 30 days period and i cant get refund i just wasted 284£ all in for nothing a big black garbage what taking only space in my room now with MSI LOGO ON IT
In MSI eyes People don't buy new rigs they just upgrade stuff
it should be like that
I was should have old PC with I7-3930K and then i decide to buy new processor that how MSI Think (Why to buy 3820k or 3930k when u can get 4820 or 4930k for allmost the same price ? )
but my mistake was i buy new processor and new Motherboard and cant get it run because in that NEW MOBO is 1.2 Ver of BIOS and without having old CPU u cant update :(

Remove the graphics card, leave 1 RAM stick inside and test outside of the case. Clearing CMOS might be worth a try together with this too. >>Clear CMOS Guide<<
Also you seem to mix RAM, unless you stated these to say you've tested both kits?
If still no go, take the CPU out and have a look if you can find any bent pins on the CPU socket.

   - Memory = 7.4
   - Graphics = 5.9
   - Gaming graphics = 4.9
   - Primary hard disk = 6.2
System is very laggy through the Menus and installs take ages to complete. Task Manager does not show massive CPU utilisation or disk I/O. Have not done anything to the BIOS whatsoever. So far, my elderly notebook performs better :(
Ideas, anyone?
