It doesn't start with two RAM modules, yet it works with just one?
It doesn't start with two RAM modules, yet it works with just one?
Hello! I'm setting up a SFF machine with the components you mentioned. I encountered an unusual problem: the system refuses to boot with 16GB of RAM, even though both the CPU and motherboard support it. I upgraded from the Core i5-4670 to the Core i7-4790K, but the issue persists. I tried using two 4GB RAM sticks in two slots, but it still only boots with one stick. Could this be due to the RAM brand or something else? Have others faced similar issues? Any advice would be greatly appreciated!
Does this apply only to the particular slot, or can either DIMM function in either of them? If it’s tied to a specific slot, it probably means your CPU or motherboard lacks a usable memory channel. If both slots work separately with their own DIMMs, it’s more likely a BIOS-related problem, considering Biostar’s past issues.
Consider replacing the old CPU and test with the previous model to confirm the problem. If the issue resolves, it's likely the 4790K has a faulty memory controller. Also inspect the socket for bent pins, which might be affecting one channel.
It seems the dust was just a small amount, so it probably didn’t affect performance. Cleaning the contacts helped restore full functionality. That’s a good sign!
It seems like something might have triggered the problem. If it's extremely small, I’d assume it was likely harmless, but definitely achievable to cause it. I’d perform a memory stress test just to confirm everything functions correctly. However, if both drives are installed and it boots successfully, you’ve probably identified the root cause.
Thank you very much for your assistance! Your support today was invaluable. Your effort will definitely be remembered!
