hi, I have the Asus CROSSHAIR IV FORMULA 890FX Socket AM3 8 Channel Audio ATX Motherboard and I am wondering whether I will be able to put 1866mhz ram in it and whether I can put either of these processors in it (8 core and 6 core)

These are the links to the peace's I want to put on the motherboard:

ram: http://www.scan.co.uk/products/8gb-(2x4gb)-corsair-ddr3-vengeance-jet-black-pc3-14900-(1866)-non-ecc-cas-9-10-9-27-xmp-150v?utm_source=google+shopping&utm_medium=google+shopping

8 core processor: http://www.overclockers.co.uk/showproduct.php?prodid=CP-311-AM&groupid=701&catid=6&subcat=

6 core processor: http://www.amazon.co.uk/dp/B004DALW5K/ref=asc_df_B004DALW5K4947549?smid=A3P5ROKL5A1OLE&tag=googlecouk06-21&linkCode=asn&creative=22206&creativeASIN=B004DALW5K

My PC currently has these specifications:

motherboard: Asus CROSSHAIR IV FORMULA 890FX Socket AM3 8 Channel Audio ATX Motherboard
graphics card: radeon HD 6870
ram: DDR3 8GB corsair 1333mhz 2x 4GB
CPU: AMD Black Edition - AMD Phenom II X4 3.4 GHz Processor
HDD:1TB

Will at least need a BIOS flash in order to recognise the cpu.
Personally I would go with the 6 core as the Bulldozer reviews have not been that flash and to be honest, if one were to go with the BD, one would be better to fully upgrade.
