I own a P6T Deluxe with an i7-920. PSU is RM650x. RAM is Kingston Blu (KHX1600C9D3B1/4G), all RAM works separately. A2 slot doesn’t show up but CPU-Z sees it. BIOS is latest, I cleaned the board with alcohol and gently brushed DIMMs. Using only A1 and A3 slots fixed it, though BSOD appears when using A2. All 3 sticks in all slots work fine except stress tests. It runs smoothly for Cinebench or Heaven but fails under Prime stress. Maybe a stuck DIMM? No signs of damage. Any tips? Thanks!
It should be possible to repair if you spot a bent pin on the LGA socket. It’s an older model, but everything else is still from its original release—about 12 years old now. You got it for free as well (except RAM and PSU), so it isn’t a major loss. My goal is to get it working again, especially to pass it on to my sister who wants to start gaming. The CPU is running at 3.8GHz and the GPU is an HD7870, which should handle entry-level games well.
I'm wondering if this hardware was just recently purchased. How do you confirm it functioned correctly beforehand? It probably doesn't matter much. The RAM modules should be placed in A2, A4, and A6 slots. If they're arranged differently, Windows won't recognize them. Do you know the voltage requirement for that RAM? It should be under 1.65 volts to avoid issues. Edit: I mistakenly entered the DIMM slot IDs. You should use A2, A4, and A6—just the orange slots.
I didn't consider checking for bent pins on the LGA. I received the motherboard with the CPU already in place, so I needed to inspect it. It's unclear why I overlooked this step. I just mentioned A1, A2, and A3 probably because those positions are familiar to me from the layout "A1, B1, A2, B2" or similar. Yes, they fit correctly. I think I lack prior experience confirming proper functionality before making adjustments. I got it from a friend who had it in his garage. So any damage is definitely a concern. However, I haven't noticed any corrosion, even under magnification, and everything seems clean—new thermal pads included. I haven't experimented with voltage or timing settings on the RAM yet, as I wanted to ensure compatibility before tweaking. But I'm confident the RAM slots are correct. To be honest, building computers is more of a passion project for me. I probably have significant gaps in my understanding. Thanks for your support and advice!
I haven't used that system since 2010; I don't recall much. I just looked up the RAM specs—it's a 1.7V model. It could be the issue, or maybe the motherboard is damaged.
Sure thing! I'll definitely give it a shot. Thanks a lot for your feedback—I really value your input! I might tweak this post in about 10 to 15 minutes if you're interested.
