CPU temp is pretty low, around 40C idle, dont think thats my issue.

Here's what I've set:

Mult: 19x
BCLK: 204MHz
Memory Freq: 1067 (2:8) = 1634MHz actual. Windows says on 6GB usable. 6x Mushkin 2GB 1600MHz 9-9-9-24-1T
Timings: 11-11-11-29-2T (want to tighten these up, currently the auto values)

CPU Vcore: 1.30V
VTT voltage: +50mV
QPI PLL: 1.350V
DIMM voltage: 1.625V

I have left everything else alone...

NB Temp at BIOS is 69-70C. CPU in BIOS is 27C, VREG 54C
From my experience i noticed that odd multipliers do not give any benefit to stability or even ability to reduce voltage. If you gonna run RAM on lower frequency anyway then just go for 186 MHz on BCLK ( you will need to mess with less voltages ). Either 186x21 or 22, you can also try keeping QPI PLL on AUTO, 1860 MHz on RAM with looser timings should be fine. Before overclocking core just make sure your RAM and uncore can pass Prime95, 6 hours preferably.

xxpenguinxx I tried messing with QPI PLL but it didn't help. This is also an engineering sample so it may have some quirks.

Just yesterday I switched it out for 48GB (6x8GB) Hynix 1866mhz ECC memory and I cannot get Windows or BIOS to see more than 16GB (meaning it's only seeing 2 sticks which is bizzare considering it recognised 4 sticks of the Dominators), all 6 sticks show up in CPU-Z with Triple Channel showing there.

I've tried bumping up PLL and QPI/DRAM to no avail, and even running everything absolutely stock with no OC on the CPU or memory with low memory speed (1000mhz) it stll only sees 16GB.


Any tips would be majorly appreciated.


Cheers!
Sometimes it just won't recognize your RAM if you install all six sticks in one time. Try to boot with only one stick installed in DIMM 1 slot (some motherboards start with DIMM 0). After booting into Windows, shut down the computer and put another stick in DIMM 3 (Dual-channel). Boot it up, and make sure the OS recognizes 2 sticks properly, otherwise give the pins a good wipe. Then put another stick in DIMM 5 (Tripple-channel), boot it up, and see if the OS recognizes all three sticks. And DIMM 2, DIMM 4, DIMM 6, just one stick at a time, one channel at a time, and reboot each time you add a stick.

Either too tight timings or too high frequency might cause this issue, i noticed QPI PLL voltage usually fixes it ( paired with proper RAM voltage as well ).

nofearek9 are all the ram sticks the same ?
are they 2R8?

Make sure all sticks are working, test each stick individually in the main RAM slot, first or rather second slot on x58 boards. If all sticks are working, try triple channel 3 slots, see if it shows up properly. If yes then add one stick and reboot, see if it shows up. The issues that you might be having, dead RAM slots, board being weird and not properly supported ( BIOS update might help ), badly seated RAM.

PotatoVonEpicus Relating overclocking i highly suggest getting RAM and uncore stable first, don't gonna expand on this too much here. Use specific BCLK which you will want for the core clock, then reduce multi and stress test uncore and RAM knowing that core is stable, then overclock core itself. Don't be surprised if core is wanting high voltage, especially if you buy used and abused CPU. Can suggest 186 BCLK ( as most boards will be able to run that ), keeping highest RAM multiplier which is 10 for x56xx Xeons, lower RAM frequencies require less uncore frequency as well ( to benefit the most from high RAM frequency you would want high uncore as well, for maximum bandwidth ), so just stay around 3200 to 3400 MHz. 186x22 = 4092, which is sweetspot for me, temps / TDP and performance wise ( running 217x19 BCLK for higher RAM frequency here, but its more of a hassle to get timings low enough to benefit from frequency ).
