im still learning how ram works any help would be appreciated this is the ram i am getting Hyper X Savage ddr3 2400mhz CL11 DIMM XMP Memory Module i just wanna know if i should use 2x8gb + 2x4gb or 3x8gb sticks thanks :cool:
 
Looks like (from Kingston configurator) the system supports up to 8GB modules, with either 1Gbit or 2Gbit memory (not sure if you'd need a bios update for the latter, perhaps not given the date of release). They're supposed to be installed in threes, so you should go 3x8, which according to Intel ark is the highest number your CPU supports. Intel ark also says the CPU supports 800, 1066 or 1333, so it sounds like you're going for a pretty hefty overclock there, are you sure that'll work? :o
 
Couple of notes:

If you are still using an older OS, especially something like Windows 7 home, you might find the OS limits to only 16GB available.

Though the official limits might state a certain amount of memory as max you might find that more actually works or vice-versa the memory controller might struggle with higher amounts of RAM without hand tuning - so running memtest86 or similar is recommended. (For example I recently upgraded an older laptop which stated 16GB max in the manual and on the Intel documentation but takes 32GB fine).

I dunno about that generation, but I'm using a not much newer Xeon - 1650 V2 rated for 1866 and the thing is nuts - the RAM tapped out before the CPU did at 2800MHz - unlike the 4820K I had in before which struggled with 2400MHz, though could do 2666 with looser timings and hit a wall there.

For those generations of CPUs the best balance of performance often came at 2133MHz with tighter timings anyhow, which you can manually do with 2400MHz RAM - speeds above that were only beneficial really for certain tasks like multi-GPU gaming for some reason which liked lots of RAM bandwidth.

i was using 3x4gb 2000mhz XMS 3 corsair ram with no problem in the past im currently using 24gb of 1600mhz ram i accidently bought lower mhz ram then i was using like an idiot i have the XMS 2000mhz ram still i could easily buy one more 4gb stick and use that i just thought i'd get better fps with 2400mhz ram as i saw someone doing benchmarks with different mhz ram and there was like a 10-15fps different with faster mhz ram https://www.youtube.com/watch?v=rj5sJARtEV0&ab_channel=TestingGames
 
Xeons on x58 dont need ecc ram, the memory multiplier on my x5670 was locked to a max of 10 so you had to raise the bclk from 133 to overclock the ram higher than 1333, i know the cpu multi is unlocked on the w3690 is the memory multi as well? other wise you'd have to hit bclk of 240 to get that ram speed.
 
ASUs made a of lot different boards under the PT6 moniker and mileage will vary between boards and CPU’s.

I managed to a get a PT6 Deluxe v1 SAS running stable with 48gb of Samsung Green. Full 48gb recognised on Win 8.1 pro. Was a bit of faff, swapping CPU’s, clearing CMOS, changing memory settings, adding memory one stick at a time and swapping slots.

my board is the p6t standard edition

im using win 10 im currently using 3x8gb sticks but its only 1600mhz i thought ram worked better when it was in channels i thought 2x8gb plus 2x4gb would run faster but is that not the case?
