Hi, the G.Skill site lists G.Skill F3-1866C10Q-32GSR as baing compatible with Maximus VI hero.
This is not the case.
SPECS:
Asus Maximus VI Hero __BIOS.v0903__SouthBridge.v05/C2
32GB (G.Skill F3-1866C10Q-32GSR) 1866HMz (PC-14900) CL10-11-10.30 1.5V (4 sticks x 8GB kit)
Intel i7-4770 (non K version)
Antec TP-550 (fully haswell compatible)
VITALS:
Total power usage is about 50W.
CPU temp 30deg C
Mobo temp 28 deg C
USAGE:
-I am only using cpu, mobo, 32GB ram, and onboard video. (no boot device attached.. no hdd)
-Also using usb keyboard and mice.
-Mobo is on the cardboard box that it came with.
-I am not trying to overclock... just trying to get good stable system before placing new parts in chasis!
WHAT I HAVE DONE:
-I have updated the BIOS. Went fine. Did a battery out and pin BIOS reset. Reset all to defaults (AUTO).
-8pin and main power cable connected.
PROBLEM:
-I am using the red start button on the mobo to start the mobo since it is not in a case.
-It boots fine.
-I see my ram is running at 1333Mhz... so I set XMP to profile 1.
The mobo at this point detects the ram as 1866HMz 10-11-10.30 1.5V - 1.25V
(This seems mostly right except I don't know what the 1.25V is for...??? this is 1.5V ram....)
Is this an issue?
-Then I choose save and reboot option.
The funny thing is it reboots into EUFI bios very fast. All seems OK.
But at this point there is not way to exit or shut down system. Exit option in BIOS just kicks me back into bios!
So I press the red start button. I only hold it for 1 sec. This shuts down the system.
-Then I press red start button again. This is where starnge stuff happens.
The mobo struggles to start. It enters what i call a boot loop. It tries to boot but after 2 secods or so it shuts down. Then tries again and after 2 seconds shuts down. This cylce repeats about 5 times. Then it sucessfully boots into BIOS. I see that RAM settings in BIOS did not get clocked down from XMP. What I don't get is if it can boot after 5 tries, why doesn't it boot after the 1st try? Why does it allways need like 5 tries?
Interesting observation is that in the boot loop, when it fails, if i look at Q led next to power plug... it always gets no further than DRAM. After a few tries it does get past it and then I have a good boot.
So I thought it was the dram. So here are a few observations about that:
-The DRAM works 100% in an AMD FXA mobo.
-When it does BOOT (it always does boot after about 5 or so tries) I can boot into Memtest and run RAM for many passes at XMP settings with zero errors.
-I tried 1866Mhz at 1.6v ... no difference.
-I tried 1600Mhz at 1.5v ... no difference.
-I tried 1600Mhz at 1.6v ... no difference.
-I tried all of the above frequencies and dram voltages with XMP latancies + 1 to each... no difference.
-I tired AUTO which is 1333Mhz... works perfect (boots always on first try).
-I tired 2 stick of RAM in red slots at XMP spec...works perfect (boots always on first try).
-I tired 2 stick of RAM in black slots at XMP spec...works perfect (boots always on first try).
-Any combo of two sticks in any paired slot works ar XMP spec.
The problem is that 4 sticks only works at 1333Mhz... on a cold boot.
If I let it boot loop 5 or 6 loops it will also boot with 4 sticks at XMP spec and mem tests do not fail.
This is not the case.
