PC not booting with 2 sticks or ram

[Andrew 545268447]

So when I use 1 stick of 4 gb ram in ANY slot, the computer boots. When I put in 2 (Of the EXACT SAME ram that came from the same packet meant for dual channel) it sometimes didn't boot or did boot but when it did, the system didn't recognize it and it was only using 4 gbs when I checked on my computer. Can someone tell me what might be wrong? This is my computer build
CPU - Intel Core i5 4690k
Motherboard - ASUS z9-AR
Graphics Card - ASUS Geforce Gtx 750 Ti
Please help, I really need 8 gbs.

Try a CMOS CLEAR. It might just be some timing/frequency conflicts. This will resolve if that is the problem.

One of the sticks might be shot

None of the sticks are shot as I have tried both of them by themselves in every slot. Both worked 100% of the time except for slot 4

Can try loosening the CPU cooler a bit and snug back down, not overly tight, if it's unbalanced it can affect the CPU and it's MC (memory controller...also ensure all sticks are firmly seated, might check for bent/broken pins (CPU/socket).....could also try increasing DRAM and/or MC voltage (maybe + 0.05 or so)

Pins are intact. Cooler is not overly tight. Sticks are all firm. Only thing left is to increase DRAM/MC voltage. Ill try that later today. 2 questions, how do you increase the voltage and what is MC?

Haven't used that laptop, but if it allows it, then you would change through the BIOS and the MC is the Memory controller, if available prob marked as CPUVTT or something like that

Ok, Ill try that. Would i change the voltage for the MC and DRAM? Or just one or the other?

 

[Tradesman1]

Start with DRAM, up about + 0.06

 

[Andrew 545268447]

Ok, after DRAM, should I do the MC?

 

[Tradesman1]

If you can and if the DRAM doesn't work, take it up a little less maybe + 0.03

Ok, if this doesnt work, Im gonna buy another set of dual channel 8 gb ram. If that works, Im gonna return the set I currently have
