Triple channel memory

[Pedro_The_Swift]

My backup Pc has an INTEL board, DX58SO, this runs triple channel memory,, but the MB has 4 slots,,
and the manual has this statement,,

"Intel? Desktop Board DX58SO has four 240-pin DDR3 DIMM sockets arranged in three channels (A, B, and C). Channel A shares two sockets (DIMM 0 and DIMM 1) and Channels B and C have one socket each."
and this off the website--



Four 240-pin Double Dataa Rate 3 (DDR3) SDRAM Dual Inline Memory Module (DIMM) connectors with gold-plated contacts arranged in two channels
1600 /1333/1066 MHz DDR3 SDRAM Memory Modules
Three independent memory channels with interleaved mode support



ATM filling 4 slots with the same brand and speed equals beeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeep on startup, filling 3 is good.

NOW I seem to have 4 spare sticks of DD3 1600 ram not doing anything--

should/can this board use all 4 sockets?

First thing to test would be to insert one RAM module at a time on each slot.
So start with the first, boot up hopefully works.
On and on for each slot until you can confirm each RAM slot and RAM module works.

Can be tedious, but "been there done that" and wouldn't want to be 'ya!

I had a quick peek, and apparently some folks have reported problems installing 4x4Gb modules on this board too.

One quoted fix is to try installing the RAM in this sequence:

Install 1 each module in the first(black) and 2nd slot(blue next to black) slot.
Boot up. get to BIOS and then power down.
Then install your next module into slot #4(not the next in line).
So that will leave a gap between #2 and #4.
Boot it, into BIOS and then power down again.
Check BIOS to make sure all ram is accounted for too.
Then install last module into the vacant #3 slot.
Hopefully this will get it going.

That's about the only info I could find on it, other than it's not a board that like 4Gb RAM modules.
Manual states 2Gb modules should be used, and to get 16Gb RAM, PCI add on cards should be used! :confused:

Anyhow, due to the major stuff around of checking each RAM if allows POST, the second method would be quicker.

must be the weather for it..

my pc is a gigabyte based 1366 with 6 slots for a total of 24g

it has been giving me ram problems for a while

last week it suddenly decided it wanted long service leave...

after much ado it is now running again but only with 12g

i have another cheaper gigabyte 1366 board here i was slowly building up as a backup for the accounts machine. been stable for weeks..

till last week...

it now only runs 12g as well but i had to get 2g x six sticks i used in the right order to get the mother to do anything other than fast beep like it was a power issue.

/life is such fun...

next time the big box plays up i will be looking for a laptop with 2 hdd and an ips screen

kills productivity big time when it plays up...

no amount of switching will make this thing boot with 4GB sticks,,,
Threw out the psu and motherboard yesterday...
sigh,,
