I have VDROP on E7500

Hello! I overclocked my intel e7500 to 3.8 GHZ, I had set the vcore voltage to 1.375 in the bios. then I opened the cpuz and it showed me a vcore voltage of 1.344 and 1.328 always changing. when I did an occt:cpu test it showed only 1.328 and did not change except of one time for a fraction of a second and then returned to a steady 1.328 in load. as well as I know this called a vdrop. My question is: is it dangerous for the cpu? should I return to a default clock and abort the OC? or ehat should I do?

My specs are:
E7500
GA-EP43-UD3L
Corsair 2X2 GB 800@830 MHZ
Seagate 500 gb
CM extreme power plus 600W
case: cm690

My voltage in the bios are:

vcore: 1.375
CPU termination: 1.3
CPU reference: 0.805 (stock)

(G)MCH: 1.3
ICH: 1.550 (stock)

DRAM: 2.00

thanks!
