1151v1 fits 6th and 7th gen chipsets (100 and 200 series). 1151v2 works with 8th and 9th gen (300 series). Yes, both have been modified—some CPUs need pin modifications—but if I were you, I’d opt for the i5-6500 and go with an i3-8100 instead of dealing with mods.
Upgrade should be considered for the new CPU. Verify your motherboard’s BIOS list—it should show the correct CPU model. Past issues with older CPUs like the i7 2600K remind me of similar problems when adding new BIOS updates; ensure compatibility before proceeding.
Thanks for the feedback. It looks like you have some tasks ahead.
This LGA 1151 model comes in two variants—one for the 100 and 200 chipset line, another for the 300 and 400 series. They don’t work together at all. Originally, Intel intended to support both generations, but they were eventually canceled. In certain upgraded boards with heavy modifications, you might find compatibility between the 8th and 9th generation and the 100/200 series. Generally, the 100/200 are considered 6th and 7th generation while the 300/400 are 8th and 9th generation.
V1 and V2 refer to the two distinct versions of LGA 1151 used by Intel. The company recently released CPUs from the 6th through 9th generation on the same socket, altering the pin configuration slightly to prevent compatibility between older and newer chips. While some 8th and 9th generation processors can run on 6th and 7th generation boards after modifications—such as connecting pins or installing a custom BIOS—it remains risky and unreliable. The alternative methods don't work consistently, especially on certain 9th generation systems.
