Thread Starter 
hi there
i have a club3d 660ti with 3570k on asrock z77 itx mobo
recently i was experiencing low scores in 3dmark11
here is what i wana show u

at stock clocks



at max overclocked so far



so any recommendations or any trubleshooting as why i am getting low score

here is stock unigine valley score



n here is when overclocked


another observation the scores in both benchmarks on stock n overclocked is almost same with a difference of just 10-100 points
n here is a screen shot of history of clocks n all


what could be the reason here

Throttling? Do you have power limit to the max? And does it have enough voltage?

In this new generation when you overclock it you need to increase power limit %(tdp) for having a stable core.frecuency and scores when you set power limit in msi afterburner it increases scores in benchs when you reached(before setting the power limit) the limit for your core

u mean to say increase it more than 100%

btw after ur idea of throtelling i was monitoring my core speed during these benchmarks n i saw that no matter what core speed i put in after burner the speed during benchmrks remain around 980-1020mhz so basicllay only the ram speed is affecting the over all performance not the core clocks
like when overclocked i put speed in after burner at 1100mhz for core ... but during benchmarks it stayed around 1020mhz max or lowered to 980mhz
so what can be that issue n how to resolve it
