Order Of checks I recommend.
1. Check your shortcut for -smp tag
2. Check your cpu usage for 100%
3. Go to HFM and check your details/How many CPU WU you have done.
4. Check your passkey
5 Check your Overclock for stability WITH HT ON!
If none of these fix your issue your answers to the above should give us enough info to get to the bottom of it for you.
Just so you know the difference between a i5 750 (4 cores, 4 threads) clocked at 4.0GHZ and a i7 875k (4 cores, 8 threads) is at least 10,000ppd with -bigadv on the 875k
