Acer Aspire x3900 i7-870 support

May be. I contacted the vendor hoping it sends another. I used mcextractor to check microcodes for my bios to ensure that I have the correct microcodes. I think the i7-870 is part of 20652 but says is not last. I don't know how to read the table below.

No, CPUID for i7-870 is 106E5
Current BIOS already has suitable microcode for it.

Thank you for your time. I’ll be back if I get a replacement.
