Solved G.skill ram in new z97x build barfs up errors in memtest86+ v5.01

[RyougaLolakie]

What's more important than what G.Skill advises is what the motherboard manual says. A single module in a channel will not run in dual channel mode. If the other channel has two modules, it's capable of dual channel mode but that doesn't mean it will run in dual channel mode. The extra module could slow access to the entire memory package. Some motherboards (BIOS) allow it but assign the extra module to System Reserved Memory or run all the modules in single channel mode. Some just flat error-out or even won't boot. It's never been advisable to have an open slot in a channel but your manual should describe if and where the extra module should be placed.

I didn't catch that you had three modules before. Windows looks at all installed memory as a single block. The modules are NOT accessed sequentially so data could be spread over the beginning of the block as well as the end of the block. (Or anywhere in between.) Having part of the block running dual channel mode and part in single channel mode used to cause all sorts of problems but I'm not familiar with the newer hardware. That's where your MB manual is your best friend.

Gotcha! Thanks for the clarification, carwiz.

Quite a few bad reviews on that board
ASRock Fatal1ty Z97X Killer LGA 1150 Intel Z97 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard - Newegg.com

Which exact set of ram did you buy
G.Skill Ripjaws X 32GB - Newegg.com

It was f3-12800cl10s8gbxl x 4 so it makes a total of 32gb ram so I guess it was in bulk oem.

As for the update, I finally found the faulty ram stick when I took out all 3 sticks of ram, I put the bad ram in the first and second slot and comfirmed to be faulty since it spews errors imediately. All the other ram sticks are fine in both 1 - 3 and 2 - 4 slots. Really thank you guys for the help.
