Brilliant! works A1 and passes all checks with intel software etc. Had to remove the sellers sticker off top of cpu and use isopropanol to take it off completely before use (a real pain), but once removed and cleaned and thermal grease applied before attaching heatsink, was perfect. A+++++
The i5 4690k has reached 4.5ghz and has been sitting stable so far, it's doing well for its age and is performing excellently. The product arrived on time and without any problems.
Have it sitting 4.5 at 1.29v at 67 average cooled with a coolermaster hyper 212 evo. Granted, I never let the cooler fan go above 1250 rpm.
