I have this 64GB kit:
http://www.newegg.ca/Product/Product.aspx?Item=N82E16820233331CORSAIR Vengeance 64GB (8 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 Desktop Memory Model CMZ64GX3M8A1600C9
I've had this motherboard+ram for about 1 year now and always had issues with booting. I've tried various firmware and currently running the latest one.
I am using XMP settings @ 1.5v but I've also tried 1.55v and 1.575v on the ram.
On the first cold boot I always get "Overclocking Failed" even running at stock. By restarting, going into bios, Saving + Exiting it boots to Windows fine.
When in Windows OCCT and Prime95 run stable with my overclock. When I put my computer to sleep and wake it up the CPU multiplier is reset. I am using Windows 8.1 and I've tried toggling C states but it keeps resetting my multiplier.
I am running 620hx power supply which is now 7 years old. I've just ordered a new AX860i so I'll see if that makes any difference.
So I have two issues:
- Overclocking Failed at stock (Only first boot)
- CPU Multiplier resetting at stock.
My Specs:
- 3930k @ 4.4Ghz 1.3675v
- CORSAIR Vengeance 64GB @ 1.5v
- Gigabyte GeForce GTX 780 Ti OC
Any ideas on what I can do? Could it be my PSU?
Thanks.
