Which Intel CPU not affect by recent issue

(1/2) > >>

Wilson__:
With BIOS updated to microcode version 0x12B, is it now safe to buy Intel Core i5-14500 because it is not on the issue list.

With a maximum turbo of only 5.0 GHz I doubt there was ever any problem with i5-14500 in the first place.

I think the problems only started somewhere north of 5.5 GHz -- and limiting the maximum boost to around that prevented damage if you hadn't already damaged your chip.

Wilson__:
Is the issue triggered by high CPU heating?

I shall be buying new CPU from well-known seller.  For 'preventive view', may be I can set fan speed curve to ramp up fan speed at lower temperature to keep CPU cooler than 60 to 70 Celsius?

exe:
I think the original issue was with overvoltage and overstress of internal circuitry. So, temperature won't help with that. May be the opposite, the cooler the CPU, the faster it may decide to work)

No, it's not the temperature. Running them at up to 100 C is no problem at all.

The problem is that the voltage settings for the highest turbo speeds were set incorrectly from the factory, and were causing something like sparks or burnout at the microscopic level.

There are lower voltages that are safe but are still sufficient for those highest clock speeds, and updated chips use those voltages.
