Hey Everyone! Sorry For me being a newbie here but I have an Odd problem. I installed identical 4 sticks of Patriot Viper 4GB 1600 RAM on my ASRock Z77 Pro 4 mobo. I can see the RAM in the UEFI "System Browser" but only A2 and B2 are recognizing the RAM as even being "installed" So It reads as I have 8156MB RAM while I should have 16384MB RAM. Any other info can be provided if it is releveant to the solution!
Ivy Bridge Intel i5 3570K 4.0GHz
Patriot Viper 16GB 1600Mhz RAM ( I hope soon!)
ASRock Z77 Pro4
Finally Resolved. I took it to my local microcenter and they replaced the motherboard for me. The Motherboard had a short on the RAM slots. Thanks for ALL the help Tom's Hardware. Geez. I couldn't have done it without the help of these so generous members.
