OK another problem need to be fixed in feauture bios update from Gigabyte. It seems that after some mhz of cpu overclocking when you up the vcore the memory performance and in result the whole performance start to decrease! Some ppl mention why I have a lower score in 3dmarks in a higher frequency? Maybe they increase the vcore and the performance decrease very much as you will see...
In the next overclocked frequency I ONLY up the vcore, nothing else! See whats happening. I first notice this in memtest as I did some tests....
In this frequency after 1.525Vcore the decrease in performance begins....
First a memory sandra benchmark with 1.5125Vcore from bios(the scores in pi, 3dmarks, real applications also decrease but I will focus in mem sandra only)
then with 1.55Vcore
with 1.5875Vcore
and finally with 1.625Vcore
the memscore in memtest was :
1.5125V 2925m/s
1.55Vcore 2267m/s
1.5875V 1712m/s
1.625V 1298m/s (problems entering bios also I need to reset first)
Then I tried with a lower more safe overclocking @ 20x153 mhz
until 1,6Vcore 2656m/s
1,625V 1992m/s
1,675V 1258m/s
1,7V 1127m/s
As you can see this is a big performance hit, and Iam waiting somebody else with ds4/ds3/dq6 to confirm this.
As you can see the Vcore bug is not standard. It may come at bigs overclocked freq. as soon as 1.525 and in medium overclocking didnt show up until 1.6V.
Also I notice a small memory increase leaving pciE @ auto(not 100+ as some ppl mention) also keep the memory performance in normal(no fast or turbo). Thats all folks
