BSOD ahcix64s.sys

Hey everyone, I am having an issue that is driving me crazy! I am trying to write this as basic as possible, but with enough detail hopefully.

This is a newer build that has never been right it seems.

Drives Configuration:
1 - SATA 256GB SSD (BOOT DRIVE) C:

3- 4TB HDD (RAID 5 DATA DRIVES) E:
OS:
Windows 10 ProCPU:FX 8320E Black Edition
Motherboard:
GA-970A-UD3P Rev 2.0
Memory:
CORSAIR XMS3 8GB (2 x 4GB)
Graphics Card(s):
GIGABYTE GV-N75TOC-2GI


The issue I am having is while copying data from C: to E: it will BSOD and give error ahcix64s.sys.
Files have to over a GB it seems to cause this issue. Any smaller files are fine. The same thing happens if I try to download large files to the E drive.

All drivers are "up to date" Bios is flashed to latest revision. The storage controller for the RAID is on 3.8.1540.11 which is from 2013. I can not seem to find any updated versions of this.

Any advice would be great!

Your RAID controller driver is outdated, however there aren't driver updates provided by Gigabyte.
Try to update your BIOS, an update has been released a few days ago.

Code:

0: kd> lmvm ahcix64s
start             end                 module name

What have you tried exactly?

Could it be a bad board?

You need to provide more information if you would want me to answer that properly. Right now I can't say anything as I've suggested 1 thing which wouldn't lead to a bad board.
