Hi,

Recently I upgraded the ram in my PC and went from 8GB to 16GB (4 x 4GB modules). The ram is running in dual channel, however literally from the first start up the PC has been running a lot slower. The ram modules are all the same speeds and same brand/models - Corsair Vengeance CMZ8GX3M2A1600C9. I noticed that CPU-Z says its running at 800Mhz for some reason. Any help as to why its running slower would be appreciated and my full specs are below.

Also just wondering, what do you guys value my PC at in £'s please.

Motherboard - MSI Z77A-G43
CPU - Intel i5 3470 3.2Ghz
Power supply unit - Corsair TX750 V2
Graphics card - (Currently onboard but will be upgrading to GTX 770 or Radeon R9 390 very soon)
Ram - 16GB Corsair Vengeance performance
Hard drive - 320GB Sata HDD

Also just wondering, what do you guys value my PC at in £'s please.
