Rod, first I want to thank you. Your video on installing Windows 7 on the SM991 was instrumental for me to create a functional system!
I also appreciate your confirmation of the read/write values for the SM991 on a Z97 board. From my perspective, the system performance has been very satisfactory, but I would like the system to operate as its full potential. Since the cost is relatively low, I’ll buy an adapter and give it a try.
As for the source of BSODs, it could be a memory issue. The two occurrences that I actually saw were only on the monitors for a few seconds – the system rebooted itself before I could read it, but I did see “Memory” near the top. (I have never had a system automatically reboot itself after a BSOD and assume that it a BIOS setting. However, I have been unable to locate the option in the documentation or the menus!)
My previous system had two 4GB sticks of Corsair XMS3 memory. So, for the new system I purchased another two 8GB sticks of the same memory. I had to play with the configuration in order to get the system to boot. I ran the Windows memory diagnostic tool and everything seemed OK, but after a few weeks and several BSODs, I removed the older 8GB and ran with 16GB.
I haven’t had any BSOD since removing the memory. However, twice I have had chkdsk run during boot and it found files on the SM951 that were corrupted. CrystalDiskinfo now says the health is good, but several errors have appeared in the event log indicating that there may still some problems (or maybe problems with some services).
Thanks again for the assistance. I’ll purchase an adapter an let everyone know the results.
