After about five years, I believe I finally stopped one of the two CPUs in my PC due to excessive overclocking. It was running at 40% overclock with an X5680 chipset, and the Vcore reached 1.55v until it failed. I suspect the issue was related to the IMC, even though I thought RAM was fine a week ago. Today it’s getting worse—can’t boot with stock clocks or even with good RAM. When I disabled one CPU and enabled the other, it worked perfectly. It seems the problem might be with the CPU itself, especially since the swap of RAM resolved the issue last week.
If you suspect the VRM, consider exchanging the chips' sockets. It might look like a CPU at first glance.
I might not be able to do it tomorrow. I’m also ordering another CPU because $12 seems reasonable. However, I’m curious if a few capacitors might have failed and the voltage is now very unstable, which could cause issues since capacitors help smooth things out. I don’t know if replacing the CPU or swapping sockets would be easier—maybe testing first would help.
It remains quite improbable, since Intel incorporates significant voltage tolerance into CPU specifications. It would be extremely rare for a CPU to fail to boot under such conditions, especially if the board was well-made and had decent voltage regulation initially. A reduction in maximum clock speed by 200-300MHz is feasible, but causing the system to not start at all is unlikely.
It runs smoothly without any posting or login issues, but it crashes right when loading an operating system. Even USB drives cause an instant reboot. It's a high-end board with an EVGA SR-2, packed with billions of VRM stages—still, the value keeps rising and that recent sale for $1G is pretty wild.
That's quite the setup. It sounds like you're experimenting with different components and trying to figure out what's causing performance issues. You're considering swapping parts to see if the problem lies with the hardware or the software. It seems you're weighing options carefully, especially since you mentioned the SR2 chips are rare. The idea of testing a different CPU and seeing if the issue is with the chip makes sense. You're also thinking about balancing cooling solutions and performance expectations for your current setup. It's a bit of a trial-and-error process, but you're doing it thoughtfully.
If you're seeing 1700MHz per core on RAM with triple channel, it's a bit unusual given your stable clock of 187-188MHz and the multipliers you've set. Your current setup uses 10x for RAM, but boosting to 1.58V or 1.53V might affect stability. Check your Vcore values and ensure they're within safe ranges. Adjustments could be needed to maintain consistent performance.
I used QPI/VTT at 1.4x for many years without issues. 1.55–1.58 feels a bit too steep; it should be reserved for bench work.
