It arrived and is working. The default XMP overclock profile locks all all cores to 4Ghz and is working with no crashes for the hour I had it applied, but on prime95 some cores almost hit 100 degrees Celsius. If I find the willpower to go through some guides I'll see if I can get an overclock with sub 1.2 voltage (the xmp had it at 1.24v), because by default it's base 3Ghz, with turbo to 4Ghz on one core while the rest max out at 3.5Ghz and the memory is 2133mhz instead of the intended 2666mhz for the kit I have.
Wonder if there is a second hand kit with some faster speeds on ebay...
On a separate note it seems that if you are sending something in/from Pakistan via mail you need to attach a copy of your ID. Wonder if they had issues with bombs in the mail so they started requiring it.
