X58 Pro Won't See 4GB Memory Module

[capt3450]

  I have the X58 Pro with i7 965, run Win 7 64 bits, most of my appl. are video editing and rendering. it worked fine with 2GB module (Corsair) but I just bought 6 pieces of 4GB DDR3 (Micron technology). Slapped in => no boot. have tried zapped with all latest BIOS up to 8.6 (8.7 is worst). I must remove at least 1 4GB module and replace a 2Gb then CPU will boot but bios report total number of RAM = total number of 2Gg module but ignores all the 4Gb pieces, so Window took this number as total system memory.. Funny part is: MSI overclock tool reads a 4Gb module and thought it's 2 Gb (meanwhile CPUID recognized these 4Gb module). My guess is max 24Gb memory for X58 pro just a marketing gimmick from MSI since they though no one will buy this board and put 24 Gb memory in it. Month ago I've tried mix with 8 and 2 Gb pieces, it won't boot at all.
  I post here to see if anyone have an idea of what's going on with this main board and 4Gb module.  For other just don't go out and pay a fortune for 4Gb then get very disappoint result.

post a link to ram showing its exact spec

only one i found was eec server ram

Well, the problem with that guess is, that it ignores the fact that the memory controller is actually part of the Core i7 processor and has therefore not directly anything to do with the board or the chipset.  So basically, if you suspect a marketing gimmick, you should probably canalize such guesses directly to Intel and their processor specifications.

OK, furthermore:

The resolution of your screenshot is not high enough to be able to really read most of the numbers.  Please make a better one.

Well, mixing different memory modules is not a good idea in the first place.  It causes problems on many system configurations and should be avoided at all costs. It also doesn't help to get to the root of your actual problem:

but I just bought 6 pieces of 4GB DDR3 (Micron technology). Slapped in => no boot.

What happens if you use only one or two of your 4GB modules?

Can you provide a link to the product site for your memory sticks and/or tell us the exact model number?

What BIOS Settings were you working with (Base Clock Speed, Memory Multiplier, DRAM Voltage, timings)?

------------------------------

There are numerous explanations for your problems that need to be checked systematically in order to get to the root of the problems.  The most crucial points are:

- Are all memory slots working properly and if not, is that because one or more are broken or because there is some sort of short circuit issue that can be avoided if the board is taken out of the case and tested on a non-conducting surface?

- Are all memory modules working properly?

- Is this a CMOS mess that could be solved by a CMOS Clear? >>Clear CMOS Guide<<

- Is the a CPU issue (faulty memory controller)?

- Is the CPU (or its contact pads) in proper contact with the pins of the board's socket?  In case you happen to have a FOXCONN Socket, please check the CPU's contact pads for imprints of the socket pins.

Read my post again. Won't boot if one or all 4Gb module(s) in there. must mix at least one 2GB.

-BTW I have this CPU/system for over six months and only worked with 2Gb module
-Brand new module, and yes it works on my computer at my work (I think they used Asus P6 MB).
-I cleared CMOS zillion times not counting the 6 times while install the new BIOS. I load optimzing BIOS, I don't OC, that's why I paid a big buck$ for i7 975
-You don't see it yet. we have about couple hundred i7 system (mostly IBM, HP and Cisco) at my work have 2,4, 8 and 16 Gb module they all worked fine...it doesn't mean I going to complain about my X58 pro (since it cheaper than one of my 4Gb module) but it's decent MB for the price.. What I hate is now I have to build another PC can take at least 24Gb for my personal work.

Now is a question for you: Do you have or try with 4Gb module in this MB before? if you have and let me know which branch?

I have and it does not say what happens if you use only one or two 4GB modules. 

I must remove at least 1 4GB module and replace a 2Gb then CPU will boot but bios report total number of RAM = total number of 2Gg module but ignores all the 4Gb pieces, so Window took this number as total system memory.. .

-Brand new module, and yes it works on my computer at my work (I think they used Asus P6 MB).

= different CPU & memory controller.  This does not tell us anything about these things:

- Is this a CMOS mess that could be solved by a CMOS Clear?

- Is the a CPU issue (faulty memory controller)?

- Is the CPU (or its contact pads) in proper contact with the pins of the board's socket?  In case you happen to have a FOXCONN Socket, please check the CPU's contact pads for imprints of the socket pins.

That also does not tell us anything about this:

What BIOS Settings were you working with (Base Clock Speed, Memory Multiplier, DRAM Voltage, timings)?

I don't have this mainboard and I am not planning to buy one either.
