Hi there. This CPU has been carefully tested and benchmarked. It has a stability issue on Core 11, which must be adjusted in curve optimiser for the CPU to be stable. On my test board (Gigabyte b550) I found a +15 voltage curve adjustment on core 11 made the processor fully stable. I did not try any negative offsets on the other cores, further gains might be possible there. Please only buy this if you understand the above and are happy making those adjustments. I could not get it into windows without those settings. If you're willing to tinker a little though, this will work perfectly well. Any further questions, do ask. All the best Jon CPU only.
