20 it is then, 20x200 - 4 GHz - RAM divider 8 - 1600 MHz. Just use stock timings and stress test with Prime95, while using lower core multiplier so you can be sure that core is stable. With uncore you probably gonna want to stay at 3200 MHz.

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.

SYNCHRON1C Thanks guys, turns out 2 of the 6 sticks were faulty, which was somehow preventing some of the other fully functional sticks from being recognised in Windows (bit strange). Ended up just sticking 3x8GB sticks in triple channel which is enough for this system.


Only cleaned them using the pencil eraser method so might try getting some contact cleaner or doing the old steel wool trick on the faulty modules to see if I can get them working.


Cheers!

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

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

I was running 16GB (4x4GB) Corsair Dominator Platinum 1866mhz fine for years with my X5675 OC'd to 4.2ghz.

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?
