I belive there were two revisions one green and black with blue pcie,  one gray and black? So It might make a diferance which revision you have.
 

 

 

you should be fine with 24gb that is 6x4gb modules i run 24gb mushkin ram at 1800mhz. im sure there are plenty of people who run 24gb on x58 boards. The reason it states 12gb cause at the time there was no 4gb ram around. I know a person on this forums successfully ran 48gb on this chipset (not overclocked though).
Good luck

I have the X58 FTW3 and recently upgraded to 24gb, runs flawlessly at 4.2ghz on an i7 920. Should work fine on your board too.

There weren't any difference between AR and TR products, as well as the Black/Grey color scheme boards were the same as the previous, just due to the overwhelming response we got from the looks of the X58 LE (E757) that we released the next run with a similar color scheme.  That being said initially I believe we stated 12gb as there were no other low voltage DIMMs out there.  Within a few months of release (exact time frame slips my mind as it was a few years ago) the support was updated to 24gb.  Now there were BIOS updates necessary for that, but all of our X58 line will support 6x4 memory config. 
There have been some who have managed to stabilize 48gb, but the IMC was never meant for it, from the 920 C0 to the 990x they are all officially 24gb procs.  Procs all had IMC's and at some level, it really is luck of the draw, sometimes you get a weak memory controller, my personal 930 has a weak memory controller, I have had to volt it to run 12gb.....
Also, in regards to Vengeance, I have seen that before as well, that in many cases all the stability issue with it was resolved by changing the voltage to 1.65, obviously that is not set in stone as how to run it, but I have seen that fix oddities before.
 
In the end 24gb will likely work fine, might not be able to clock it as well as you like, and latency will also likely increase, especially if it takes you 2 kits of ram to make your 24gb.  48gb is hit and miss no matter how you slice it, and is not officially supported.

I am running 24gb (3x8gb) Corsair Dominator Platinum 1866 @ 1.5v 9-10-9 on a e762 mobo
 
Very solid

make sure you are running the 64 bit windows, you may need a bump in Vtt +150 should do it; command rate T2, 9,9,9,24

Great, thank you for the help, guys. I should have it in by Friday and will update as to how it went.  Thanks!

if you use a xeon chip (which has a much higher max ram support in its IMC) will the board support more?

Hi all,

sorry for hijacking this tread. I also have x58 sli board with 3x2gb ram.

My question would be will 2x8 gb work on this board?

I would like to buy 2x8 now as I will change board in the next 6 to 12 months.

thx in advance

if you run only two dimms then you will be in dual channel instead of tripple channel mode

I am only interested in how will this affect games. (2ch vs 3ch).
 
Primary reason for me buying more mem is Skyrim. Right now game works great but in about an hour of playing mem usage goes to 90% and it starts to affect performance.

Hi to all.
 
I have a X58 SLI Motherboard EVGA Classified3.
 
with an i7 990x at 3.46GHz
 
I have 12GB of triple channel memory (Corsair Dominator CMP 12GX3M3A1600C9) and would like to install 24GB.
 
Any one know if is possible?
 
THANKS!
 
(sorry for my poor english)

Maximum memory does not mean maximum performance. There is a sweet spot. I have found that 12 gigs is it on  my x58 980x at 4.5ghz. The more memory you put in the slower the timings and actual speed. I can achieve 7 8 7 20 2000 with 6 gigs. 12 gigs I get 8 8 8 24 1866. 24 I get 10 9 9 27 1600. You might use more virtual memory with less ram but it ends being faster in the long run especially if you have a fast ssd.
