i just got my 2nd X58A - UD7 and have a strange ram issue that doesnt occur on my other UD7 machine.
I have got 6GB of corsair XMS3 1600 mhz ram TR3X6G1600C9 kit in both the UD7's. My earlier machine is completely problem free while this new UD7 i just got is giving me a headache
My new Gigabyte X58A - UD7 Ram shows only 4 GB out of 6 GB installed.
Only way to get it to show the full 6GB is to unpulg the power supply from the mains for 10 seconds and then reboot. After this it will show me the full 6GB until i shut down the computer.
BUT now if i start my computer without doing a complete power down from from the mains then i will only get 4GB again !!!
Unplug the mains and power back up and my 6GB is back..
This behavior is 100 % repeatable as is shown in my video ..
All my ram has passed memtest and 15 runs on LinX with full ram usage so i know the ram is fine. Besides i checked the ram in my other Gigabyte UD7 system and it works great there too . No memtest or LinX Errors so its not my Ram.
And i took out the ram from my earlier ( 1st ) UD7 machine and it does the same thing here.
Have tried to re-seat the cpu 3 times already and also tried the stock intel heatsink thinking that maybe my noctua NH-12 is putting too much pressure on the chip/socket. No change at all
My question is RMA time ? or is there something else ?
Sorry for the long read and thank you guys tons in advance !
Cheers and kind regards
