Experiencing problems with dual-channel RAM setup.
Experiencing problems with dual-channel RAM setup.
Hey there. I see you're dealing with a RAM problem on your new PC setup. It sounds like you're trying to run two 8GB DDR3 1600 modules at once, but the system won't boot until only one is used. With the H81 motherboard and your i7-4790 CPU, this could be related to how the motherboard handles memory slots or compatibility settings. Have you checked if the RAM sticks are properly seated in the correct slots? Also, make sure your BIOS is set up to support dual-channel or that the slots are configured for two modules. If you're still having trouble, reaching out to the manufacturer's support might help. Let me know what you find!
Are you referring to a boot-up that shows a black screen with fans spinning and no display? Could you provide the model numbers of the sticks? It seems you're using the latest BIOS. Have you inspected the pins on the board and the pads on the CPU for any signs of damage? What type of cooler mount are you using?
It might be due to a faulty RAM stick or a damaged RAM slot. Another likely reason is a bent or broken pin in the CPU socket. You can test each stick individually in both slots to determine if it's the issue first. If one works in one slot but not the other, it suggests a problem with the board's RAM slot itself. If it's a slot, inspect the CPU socket for missing, broken, or misaligned pins. Also, note that when you refer to "Off Brand," which manufacturer built the board?
Hey, it seems the system will start with a black screen while fans spin, no TV or any external devices connected. The stick model you have is F3-12800CL10D-16GBXL from G.Skill. I thought my BIOS was current and looked online to confirm, but wasn’t sure how to update it. I verified the CPU pads on the board and everything appears intact—no bent pins, pad damage, or extra thermal paste. The cooler uses an LGA 1700 mount. My stock Intel fan is a standard one with a blue ring and no illumination. Let me know if this helps. Appreciate your response.
Hey there, I gave those techniques a shot but will definitely explore some of the ones you suggested too. I verified whether each stick fit into the slots and everything seems to function properly. It looks like the CPU might not support dual-channel RAM, even though it's a 4-core chipset. Also, the motherboard didn’t have any branding on the box—just a generic "Motherboard" label. I bought it from Amazon and based on my research, it seems to be a generic Chinese H81 board. Thanks for your assistance with this problem.
Interesting setup... The quad-core processor doesn't change how dual-channel RAM works. It seems the issue might lie with the board itself. I'm going to review my previous advice and proceed carefully, especially when handling the pins. Having a good light source and a magnifying glass would be really helpful for checking.
CPU-Z and/or hwinfo offer additional details. They often reuse chipset information, occasionally even for different generations than the motherboard.
