Hi all, just bench my cpu and bad surprise on 3dmark11 with P test. Only 8800 points with stock frequencies (3,8 cpu boost) other results for this cpu show often 10000 or over...and with oc 4.5ghz i have only 9800 points.
I'm using windows 8.1 with asus z87i pro mini itx motherboard.
I try cinebench r11.5 résultat is 8,03 with stock frequencies.
My chipset Intel driver are the latest and be fore tests my cpu usage is less than 1%.
Any ideas about low score with 3dmark11 ?
Thank´s for your help

But my result is below 9200 only 8800 3dmark physics score and with cinebench R11.5 result is only 8.03 with stock clock (turbo enable). All bench show à result around 8.15. I don.t understand why i have still poor result...
