Bad eBay luck or a planned hit from PSU?
The CX750 is a solid and dependable power source. It might be worth testing another one just to confirm, but I’m not sure it’s the issue.
i began doubting the PSU if there had been enough GPU failures, especially with RAM and board issues. So i switched it to something better quality like an RM850X or similar used models. It’s probably just bad luck since i’ve got four already, except for the Tundra 700W which failed due to a broken board. It seems the board is the real culprit here. These are all lesser-known PSUs (Dazumba, Tundra, ZumaX), but they’re not great overall. There’s a CWT but it’s more of a Corsair OEM for the P5Q Pro—likely dead Southbridge. It should be fixable if you replace the Southbridge, but honestly these boards are poor compared to Ep45 ones. Most of them don’t handle overclocking well, even with premium sticks like the 1066C6. It’s not worth it unless you upgrade to a top-tier board like a high-end 2GB stick or a premium BWT2G. Micron D9 based is best for stability, or OEM micron sticks marked “HP” sometimes. The best DDR2 ICs are limited, but for max speed you could try 775 or higher-end ASUS boards. For now, it’s average around 4.2-4.3, but with a QX ID this might jump to 4.5 or more if the board isn’t binned. I’ll stick around if I find a solid high-end board or learn more about voltage tuning.
