2nd 8-pin CPU power connector on Big Bang XPower

I am currently using both 8-pin CPU power connectors and am wondering if it is really necessary with my current overclock. For all the BB XPower owners let me know your thoughts on this.

When doing early tests with the BB Xpwr, I only had a single 8 pin CPU connector ( PSU was single +12V Rail). Since it was not necessary but recommended, I purchase an 8 pin Y cord manufactured by Athena. It worked perfectly until I got a newer double cabled 8 pin PSU (Single +12V rail Corsair AX1200). I also supply power to the boards 6 Pin JPWR4. As Jack says, if the PSU has the connectors (or use the Athena), fill 'em up with power!

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.

4-pin CPU-PWR connector on x99s SLI Plus

I'm attempting to install a Kraken x-61 cooler into my Corsair 780T case and the MSI X99S SLI Plus mobo. One step says:
Connect the 3-pin power cable from the pump to the 4-pin CPU-PWR connector on the motherboard.
In the MSI x99S SLI Plus mobo and the manual (En-6) I can't find anything called CPU-PWR. The 3-pin power cable fits into the 4-pin CPUFAN1 connector, but I don't know if that's the correct connection. Could someone tell me where the CPU-PWR connector is on the MSI X99S SLI Plus motherboard?

it can be confusing to start with but you get used to it once you have done it a few times!
so yes connect it to the fan header for CPU as that line has a sense pin that will detect if your pump fails and will shut the computer off to prevent the CPU overheating to stop it breaking the processor! just take your time and anything your not sure of feel free to ask us!

Information on Sun Ultra 5/10 PSU regarding 6-pin AUX power connector

I've been messing around and reviving my old Ultra 5 and Ultra 10 machines. I've been considering upgrading the ATX power supply to something more modern, quiet, and 80Plus. From the hardware documentation, I have already confirmed that the 20-pin ATX main power connector is exactly as specified for ATX v1.3. So, any modern ATX PSU with a 20-pin or 20+4-pin main power connector should suffice in that area. However, on the Ultra 10, the 6-pin AUX power is also used. I'm guessing this is probably to power the UPA graphics stuff (Creator3D/Elite3D/etc.) since the Ultra 5 has the connector on the motherboard but the PSU doesn't supply any power to that 6-pin.
Looking at the 6-pin connector, it is orange-orange-orange-black-black-black. Typically, on PC hardware, this 6-pin is red-orange-orange-black-black-black. Does this mean Sun used a slighty different 6-pin AUX? I.e., instead of 2x 3.3V + 1x 5V line, does Sun use 3x 3.3V lines? I suppose I can just measure it, but it would be nice to have a 2nd opinion just so when I do measure it, I have some confirmation of what i'm seeing from someone else.
As FYI for anyone else, the U5 with a 10K RPM SCSI disk and 'glm' based SCSI controller draws only 60-65W, while the U10 with Elite3D draws almost 130W!!!! I'm hoping i can find an appropriately spec'd modern PSU since the power requirements on these things are so low!

four of the eight connector receptacles are blocked with a removable piece of plastic. Why is this?
You can safely remove the cap and use the additional four pins, if your power supply has a proper connector. Four of the eight pins are covered to avoid confusion with PSUs that only have a 4-pin connector.

Problem 2: PSU-mainboard compatibility
The Enermaxx LIBERTY DXX 620 SLI (ELT620AWT-00) is listed in the MSI PSU compatibility list. It does not have a -5V-rail either. You should be fine.

Problem 3: PCIe power connector
Use one of the 6-pin connectors of your PSU. That way you can make sure that the power load is balanced. Those adaptors are usually for PSU that do not provide 6-pin PCIe-plugs.

Quick question on 8-pin ATX Power Connectors

First, I am very VERY new at building systems. I was building a Athlon 3800+ X2 system with a MSI RD480 Neo2-FI motherboard and ran into a 8-pin ATX Power connector. Unfortunately, the 450 Watt PSU that came with my Antec Sonata II does not have that plug. The Computer Renassaince guy told me to just plug the 4-pin into the mobo and it would work (personally, I think he is nuts). Question, is he right? If not do I have to buy a new PSU or can I use some type of adapter?
Again, realize I am very new at this. Thanks in advance.

You mean that there is a 8 pin connector on the mainboard is for cpu power supply and your own power supply doesn't have such a relevant
connector. If in that case, then the guy who told you to use the 4 pin connector is right, most of the time, it would work. You don't need to buy another power supply. Please firstly have a try.

Computer won't power up if the 2x2 CPU POWER connector is plugged in

Yesterday I assembled this computer and it was working great. Played games on it and everything.
MSI K9a2 CF, ATHLON 5000+, LC POWER 550W, RADEON 3850 256MB, 2x1G SUPER TALENT 800MHZ RAM.
3 hours ago I went to the store and left 2x PRIME95 torture test running just to check for stability. After 2hours I got home only to find out the the computer has been shut down but the KEYBOARD still had a light on the NUMLOCK led.
So then I unplugged the PSU from power and started up again. But the PC only started for half a second and then the power went off.
So I pulled everything out of the board only to find out that if the CPU POWER 2x2 connector is in the board then it will not power up. Then I also took out the cpu and try to power up without the CPU and with the CPU POWER 2x2 connector in and it also doesn't power up.
Conclusion:
If the 2x2 CPU power connector is in the MB regardless if the CPU is in or not then the computer will not power on. But if the 2x2 CPU power connector is absent then the computer powers up. But that don't do me any good since without that connector the CPU can't function.
I also tried hooking it up to another PSU but it does no good. The MB, CPU, GPU, RAM, HDDS are only 2days old.
Also it couldn't have overheated since the temperatures never went higher than 50C during full load thx to Scythe Ninja Revision B cooler and also there is no smell or any indication that something could be burned. The temps were checked with BIOS as with MSI probe.
My question is is the MB the problem?? So I would know which part to send back for warranty

Do you use system stock parameters?(No OC)
Check CPU cooling system.
List PSU details(Look over PSU sticker for them)
Everything was at stock speed there was even no tweaking involved.
CPU cooling system was working great. Under load the max temperatures it had gotten was 50C. And also the CASE was opened so there was no chance of overheating. And also when I started PRIME95 I opened the window and closed the radiators which means the room temperature was about 15C celsium only.
LC POWER 550w 140MM fan.

It is probably the board right? I must know this quick to RMA it

HPE-210f, one 4-pin ATX power connector support USB card ?

For my Pavilion Elite HPE-210f, Product # BK169AA#ABA, HP support, Motherboard Specifications, H-RS880-uATX (Aloe), shows my PC as offering "one 4-pin ATX power connector."
Does that "ATX power connector" meet the requirement for a "5V 4 pin connector" to power a USB 3.0, 4-port, PCI-E Express Card that I wish to install? With no free PCI Express x16 slot, I can't mount a GigaBit Ethernet card, so the USB 3 card seems helpful, apparently faster anyway, for connecting to the SS-USB port on my Gigabit switch.
How do we decode/understand the P-codes (ergo, P3, P5, I think I recall) on the power connectors on cables from the power supply?
Also, the PC board specs promise "Three PCI-Express x1 (Gen 2.0)," and "One PCI Express x1 minicard socket (Gen 2.0)." I cannot identify the minicard socket, but I do see three identical PCI-Express x1slots, with only one occupied, so the slot requirement looks fulfilled.
Power cable OK? Comments, advice? Thanks!

No, the 4-pin ATX power connector is for the motherboard. If you have a link to the USB card, send it. Some use a 4 pin peripheral (molex) , some use a 15 pin Sata power lead.
I am sending this link. It explains all the various connectors of the typical PSU.

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 Power won't post (d4 debug) (again!)

Specifications:
MSI Big Bang XPower Mainboard
Rosewill 1100W Bronze Edition
GeForce 465 Fermi
Corsair Dominator DDR3 1886 6 x 2GB RAM
Intel i7-930 processr
Issue: System powers up for about 30 seconds, the debug indicator gets to d4 (indicating problem initializing the memory per the handbook) and doesn't post. System will remain running however (different from another guy on the forum having a nearly identical problem.)
I've tried rearranging the RAM. If I put a stick in the first blue slot the debug reads E8. I've tried using various single sticks in the first black slot closest to the CPU (all produce D4). I've checked the CPU socket pins to make sure they aren't bent, and I've tried reseating the CPU. I've checked that both 8-pin 12Vs are connected and secure as well as the 24-pin connection. I've tried using three sticks of ram at once in the black slots with no success either. In another thread user HU16E verified on Corsair's webpage that this RAM should be working with this board.
Finally, in another thread a user with an identical processor, mobo, and RAM (only difference on the ram being he has 1600 and mine is 18XX, I think 1886) demonstrates the same exact problem. Our video cards and PSUs differ.
Looking for the next step in determining a likely culprit. It seems odd to me that this set of corsair ram might be incompatible, but that's my current hypothesis because it seems even stranger to me that another user would be having the same problem. The chance of both of us getting faulty motherboards, faulty processors, or a full set of faulty ram seems remote.
Edit: Also did a benchtop test with just the PSU/CPU/CPU Fan/1 Stick of ram in the first black slot, D4 error.

Quote
but if you think its worthwhile to check using the stock heatsink I'm more then willing to give it a shot.
Yes, please give that a try. Use just one stick in the primary black DIMM 1 slot.
Quote
With the one sided clasp for the ram I was very liberal about pushing it down into the slot and applying a fair bit of force to make sure it sat correctly.
I found it to be rather tricky too.
Quote
If its a BIOS problem can I fix this without having a 'working' stick of RAM?
Unfortunately, no. If your board is a version 1.1, it should have a current enough bios to at least allow it to fire up with your RAM. Do any of your friends have a DDR3 rig to test your RAM in to make sure all the sticks are good?
Quote
The odds of getting two bad boards (and the other user getting a bad board and having the same problem too) seems really remote to me, but I haven't built enough PCs to say that with any confidance. What do you think?
If they are from the same manufacturing batch....... hmmm! Possible.
Added: One of the forum users, Aaron, had 4 bad boards in a row. X58 Pro-E I believe they were. Same batch. MSI needs to know right away if a certain batch is having these problems. Have you got a ticket in with them yet explaining your difficulties?

MSI Big Bang-XPower II More MB RAM than the CPU can handle...

I understand reading in a few forum post :" By making more memory available to the system more data can be cached in RAM, so there will be less hard drive activity, and less swapping to memory so your system will perform better." But what happen when motherboard for a desktop that supports( and had install) more RAM than the processor can handle?(aka:processor Max Memory Size).
Please comment in this configuration.as I 'm looking for a MB than offer me the more SATA6 connection i found a few available using LGA2011 socket (MSI Big Bang-XPower II LGA 2011 Intel X79 SATA 6GB/s USB 3.0 XL ATX Intel Motherboard with UEFI BIOS) than support 128GB. As I understand the processor Intel® Core™ i7-3930K Processor only work with 64GB.
Is there any advantage to have a MB that hold a bigger RAM capacity than the CPU? If so, how can this be translate using in a program like Adobe After Effects, RAM preview? thank

More Memory doe's not make it faster as its Volatile Memory (more RAM but it has to be run at much slower speeds) that is very short term and is just a buffer for active Programs and files it Caches there while its active but in no way improves system speed (as it has to be clocked slower to allow the IMC on the CPU to cope with it)! more memory just allows more Active Large programs and files open at the same time and huge amount of ram will only really be of benefit for things like Video Editing, photo editing and 3D rendering as those take alot of ram to allow all the computations that the CPU does to be held for quick access but only when they are active!
having more RAM then your CPU can Handel is a VERY BAD IDEA as it will just refuse to even post or in very rare cases damage the CPU's IMC leading to a dead CPU!
why MSI have done that is for possible later 2011 CPU's that may allow the 128GB of RAM limit to be used but currently they do not exist currently as X79 is a more professional grade Platform that will probably be around for years to come (may be used for many upgrade cycles and may eventually have a cpu that can use 128GB or ram) and who knows what will happen with Intel CPU's in that time frame! (more of a possible forward compatibility thing as its a very high end platform)
as for after effects it uses RAM for holding Render Files so in theory more ram will just allow it to render Larger files that are more complex without hitting the Available Ram ceiling that your computer has but it will not render any faster as a result it just gives it more headroom to work in!
so overall more ram = more Active space available & no increase in speed (actually maybe a drop in speed as it needs to run slower causing LAG/Latency) so it all depends what is important to you here to whether more ram is of any benefit or just a hindrance but that is down to your own use case scenario!

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 did not post - Debug LED Code #67

I need HELP...!
I have a problem my board did not post , did not start and i have the DEBUG LED CODE # 67 displayed.
There is my build

Ultra LSP-750 Power Supply
Cooler Master HAF X EATX Tower Case
When I put the power on, the power supply activated fans and drives spin, all the LEDs on the motherboard light up but nothing appears on the screen.
No video signal at all and the computer stop and restrart every 15 seconds. When these reset occurs there is no beep on the speaker , nothing at all, no flashing screen either, nothing.
The DEBUG LED display a sequence of flashing numbers 19 - 60 - 19- 60 - 67 and stop showing still the number # 67 for about ten seconds and then he reset again.
I carefully followed the instruction manual for the installation, I installed the memory modules in slots 1 3 5 7, i put my video card in slot PCI-E2. all the power wire are connected correctly 1 x 24 pins ATX, 2 x 8 pins ATX, 1 X 6 pins , all the wire from the front panel are correctly connected to the m-connector in JFP1 & 2.
Did i forget something, I don’t know what the debug led code # 67 exactly mean and what i have to do to fix-it
Someone has an idea what is wrong or have any suggestion to solve this issue.
Thank's all for your help.

I followed some advice to remove the memory modules and this is actually caused by the use of memory but you will see I still have a curious bug.
I referred to the instructions manual to the letter for the choice of DIMM SLOT to put the memory module in single, double, triple and quad channels.
If I install 1 memory module in the DIMM SLOT 1 to operate in single channel, everything is normal and the motherboard POST normally and show the SETUP SCREEN.
If I install 2 memory modules in DIMM SLOT 1 & 3 to run in dual channel, everything is normal and the motherboard POST normally and show the SETUP SCREEN.
If I install three memory modules in DIMM SLOT 1 - 3 - 5 to run in triple channel, everything is normal and the motherboard POST normally and show the SETUP SCREEN.
As soon as I install four DIMMs modules mémoiredans SLOT 1 - 3 - 5 - 7 to run in quad channel, the motherboard freezes and does NOT POST and show code 67 on the debug led and has reset itself every 20 seconds.
I tried all my RAM modules alternately in both single channel and everything works normally.
I did the same thing in rotation for both dual and triple channel and everything is still normal with all fourth memory modules individually.
As soon as I put a fourth memory module it freezes and displays the code 67 or L9 dependent side as you look.
So my bug is my motherboard MSI Big Bang Xpower II do not want to work in quad channel.
Do you have any idea where I should look for, is a setting in the BIOS , I have flashed the bios to the latest version V1.5
I included the screenshot of the BIOS to see if you can notice something wrong.
Thank you

Seeking help with Big Bang XPower board, please.

Hi Guys,
I'm a noob to upgrading computers and am hoping somebody can help me. I have never overclocked anything before or changed BIOS settings. However I just installed the Big Bang XPower Board, into my old Dell XPS 730x and added an Intel 980X chip running Win 7 64bit. I have read about the BIOS settings on the MSI site but I am still not sure about some things. I have listed my hardware below and am trying to figure out how to get the best performance out of my system. I would like to know what other BIOS settings to change to get the most out of my 980X CPU and RAM without completely stressing my system. I want to utilize this board and the components but I also don’t want it running at max non stop... so somewhere in the middle. I’m in the USA if that matters as well. If anybody could guide me as to what I what I should change in the BIOS for this id really appreciate it. Here is what my system consists of:
5 HARD DRIVES:
(1) SATA II WD 3gb Hard Drive @ 1.5TB
(2) OCZ SATA II SSD drives @120GB: http://www.newegg.com/Product/Product.aspx?Item=N82E16820227543
(2) Hitachi 6gb SATA III drives @2TB: http://www.newegg.com/Product/Product.aspx?Item=N82E16822145473
3 DVD/CD/BLUERAY DRIVES:
1 SATA DVD DRIVE
1 SATA BlueRay Drive
1 SATA CD Drive
(So 8 SATA Devices Total)
24GIGs of this ram: http://www.newegg.com/Product/Product.aspx?Item=N82E16820145321
1 NVida Geforce GTX 470
1 Soundblaster X-Fi Titanum Card
I have all my hard drives on the SATA II ports as suggested by a forum member. I have my Blurray on a SATA II port as well, and my other two disk drives on the SATA III ports.
I do have the system up and running, its just not that fast, and I expected with this setup for it to be BLAZING. Hence why Im looking to you guys. I currently have the BIOS set to “failsafe” mode, b/c if I don’t when I turn the system on, it runs for 5 seconds, then reboots, the comes back on and loads windows... that seems odd… yet it doesn’t do it in failsafe mode or if the Genie button is pushed.
I also don’t want a RAID setup, just each drive acting alone. Yet, the Maxell software still runs before Windows starts. Is there a way to stop that since Im not using raid?
Any info, advice, or a point in the right direction would be greatly appreciated.
Best!

Hi guys,
Ok, so Im not really making any progress with this. I havent done anything with the memory yet b/c I trying to solve the booting issue first. Here is what I have tried, but nothing worked:
Set BIOS to optimal settings which causes booting issue (turns on, then instantly turns off, then boots win 7 successfully). I shut down and restarted 2 times, but both time I still had the booting issues.
I disabled EuP 2013, and still had the booting issues.
I disabled EuP 2013 and Spread Spectrum, but still had the booting issues.
So I reloaded failsafe settings and it was fine.
STARTING OVER I loaded optimal settings again, and disabled everything in the CPU Features menu except for Hyperthreading, Execute Bit Support and Intel Virtualization Technology. This also did not solve the booting issues.
I added the disabling of EuP 2013 to the above, and still had the booting issues.
Then I added the disabling of the Spread Spectrum to the above, but still had the booting issues.
So now I am back to the failsafe settings. Could this be a hardware problem, or not since it works in failsafe mode.
I also wanted to point out I only added they extra 3 stick of memory a week after I started having this problem. So while there are 6 sticks of memory in now, I have had this booting issue since the first time I booted the new mobo, and for a week of only have 3 memory sticks.
So any idea what I should do now? It just seems odd that failsafe works, and turning OC Genie on to max it out works, but nothing in the middle.
I look forward to hearing back from you guys.
Best,
moxy
P.s. Dilburt you asked about the power supply im using previosuly. Heres the info i got: "The Dell 1000 watt power suplly 12 volt rails are rated at 18 amps each. That's why only 2 x 6 pin PCIE power connectors vs the 8 pin PCIE connectors."

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.
