Hello,
I have been yesterday reading a lot here in tomshardware but also in the G.Skill forum, and I tried many failed combinations.
Hardware
I am a bit crazy about the 1866 Mhz. I have this computer:
Status
Tests
I have tried multiple configurations:
I am just trying to increase the memory speed, not the CPU speed, but if it were necessary I would do it.
I have read tons of posts of different threads and forums.
Voltage
I have to say that by default I get only DRAM 1.488V, and the only way to get DRAM 1.5V in the MIT STATUS of the Gigabyte is by setting the DRAM to 1.515V, but leaving the XMP disabled and setting the speed to just 1333Mhz. If I tried in the next reboot to increase the speed to 1600 or 1866 after being sure that the current DRAM voltage is 1.5V, it fails and it is resetted to 1.488V and the speed goes down to 1333Mhz.
Other tests
I did some tests to be sure it works correctly under other combinations:
Dual Channel A combining three different pairs: it always get 16GiB at 1866Mhz with XMP Profile 1 (I did not try Profile 2 but It would work the same).
So, apparently the cards are OK.
Thank you in advance!

Hardware
I am a bit crazy about the 1866 Mhz. I have this computer:
- CPU AMD FX 8350 8 cores @ 3.2Ghz
- Motherboard Gigabyte 990FXA-UD3 R5 (latest BIOS F2)
- Memory G.Skill (4x8GB) DDR3 1866 Mhz 32GXM (so, 2 dual channel) Timings 9-10-9-28
Status
BCLK 200.90 Mhz
CPU Freq 3214.00 Mhz
Memory Freq 1339.88Mhz
Memory Size 32768MB
CPU Temp 20ºC
VCore 1.284V
Dram Volt 1.488V
CPU Vcore 1.27500V
Dynamic Vcore (DVID) + 0.00000V
NB core 1.17500V
Dynamic NB Core (NB DVID) +0.00000V
DRAM Voltage 1.5V (although in the other part it, in the status it says the real is 1.488V)
DRAM Termination 0.750V
HT Link Voltage 1.200V
NB/PCIe/PLL Voltage 1.800V
CPU PLL Voltage 2.500V
NB Voltage 1.100V
Vcore Loadline Calibration +100%
Tests
I have tried multiple configurations:
- XMP Profile 1
- XMP Profile 2
- manually setting 1866Mhz
- also trying 1600Mhz
- increasing the NB Voltage to 1.2 and even 1.25
- increasing the DRAM voltage to 1.515, 1.55 and even 1.6
- setting manually 1.5V
- setting manually the timings that are by default detected correctly
- mixing previous combinations like: XMP Profile 1 + NB Voltage to 1.2, XMP Disabled + Manually 1600Mhz + DRAM voltage to 1.515, etc
I am just trying to increase the memory speed, not the CPU speed, but if it were necessary I would do it.
