Problem with your slot machine. Need assistance resolving the issue.
I recently received a gigabyte motherboard for my i7-3770, but two RAM slots aren’t functioning. I’ve tested various combinations, and only one pairing works (1+2 = yes, 1+3 = no, etc.). It seems the issue isn’t with the power supply.
I purchased three Gigabyte P67 boards and one Z77X board for two i5 2500K and two i7 2600K processors. Each was bought a few months apart. Initially, all had two 4GB RAM sticks, but when upgrading to 16GB only the latest two boards could fit four sticks, while the older ones required eight GB sticks. Firmware updates didn’t help much. I bought these in 2011 and upgraded them to 16GB in 2016, which ended their warranty period. I’ve faced similar problems with ASUS A8N-E boards (Socket 939 AMD) switching from four to eight GB, something I was familiar with back then. The ASUS P5N-Ds (Intel socket LGA 775) that replaced the AMD models also had issues, though I only upgraded two of the four I bought. Since 2016, I haven’t used more than four sticks in any of my boards (LGA 1151), but if half of them failed, I wouldn’t be surprised.
In theory each stick would function, but for full reliability you must use matching sticks. When searching online for your motherboard model, the manufacturer’s site appears in results—clicking it reveals details about compatible RAM sticks. For more comprehensive help, read the manual; it’s also available for download on the support section of each brand. To confirm compatibility, check the manufacturer’s QVL list (usually under support or download). The QVL shows which sticks they guarantee work with. If not listed, it doesn’t rule out use but also doesn’t confirm it.
Every stick functioned. The two computers requiring four sticks were acquired. The remaining two received 8GB sticks. The variations in three motherboards stemmed from their revision numbers. Back in my business days, I purchased numerous motherboards and RAM. The problematic ones are still with me, while the others are completely forgotten.
