Hi everyone.

I built a new Photo / Video editing machine just before christmas.
I had a few issues to start with but once setup everything has been running fine.

About a week ago I had a series of BSODs and when I checked
One of my ram modules had failed.
I have since got a replacement under warranty but I am now having stability
issues with all four ram modules installed.

With All four modules installed I cannot get the system to run stable and shows errors with prime95 and on test 7 of memtest86, It does this even at base spd settings.

If I only have 2 sticks installed the system is stable with xmp enabled and there are no errors with either memtest86 or prime95.

I have tried upping the voltage from 1.5v all the way to 1.65v and it still fails.
All voltages are set and timings set correct.

Has anyone had issues like this or can anyone shed some light on the problem.

For information the system spec is as follows:

Gigabyte GA-Z87X-UD3H rev 1.0 BIOS F8
Intel I7 4770K CPU
32GB RAM - 4x8GB Corsair Vengence Pro 1866 C9 (two kits)
Corsair H100 Cooler
Be Quiet 850W Power Supply
Gainward Phantom Geforce 770GTX 4GB
500GB Samsung 840 SSD
2x WD Black 1TB Sata Drives (Raid 0)

I am really at a loss now so any help would be great

Thanks in advance

Thanks for the reply.

I have tried increasing the following and nothing has worked.

vcore - increased to 1.249
CPU System Agent - increased to + 0.15
CPU IO Analog and Digital - Both increased to +0.15
LLC - Set to Turbo
 
Tried with xmp, voltages and timings set to auto = no go.
without xmp at 1866 and voltages + timings set to auto = no go
without xmp at 1866 and voltages + timings set to manual (9|10|9|27)
without xmp at 1600 and voltages + timings set to manual (9|10|9|27)= no go
without xmp at 1333 and voltages + timings set to manual (9|10|9|27)= no go
without xmp at 1333 and voltages + timings set to auto = no go

At all of the above settings I can boot into windows.
I either get a BSOD or prime95 will fail within about 10 seconds using blend.
memtest86 also shows errors on test 7

Yes I am running the latest BIOS

tested both kits one by one in memtest? you could have a faulty stick somewhere

Hi had tested them using the windows test and found nothing and tested using what is now passmark memtest86 and found nothing.

However, Last night and this morning I used memtest86+ (The open source version).

I ran a test on the new RMA'd modules for 8 hours without a glitch.
This morning I ran the same test on my other 2 modules and got a number of errors.

It looks like I have another faulty module, which I will be getting RMA'd tomorrow. Its interesting that neither the windows tester or the new Passmark version of memtest86 did not find any errors unless all four stick are installed but the new open source branched version of the original memtest86 has.

I will get some replacement modules and see how things go.

Thanks again for all the help and I will update once I have the new ram modules.
