Ok, i have been overclocking for some time, incorrectly it would seem, i have a new GTX 680 (Evga) and a 1090T CPU.

My overclock seems to give me LESS performance, so im thinking there is a bottle neck somewhere and i cant seem to find it.

i set my multiplier to 20.5 for a 4.1Ghz overclock, and keep my GPU at its base clock, and run firestrike scoring around 5100...

When everything is at its stock clocks i scored in the 6200's

My system specs are

Sabertooth 990fx
AMD 1090T BE
GTX 680 Boost
12G gskill 1333 RAM
OCZ vertex plus
1TB WD black
GS800 Corsair PSU
CPU is being cooled with a Corsair H60

Any information you may need to give me a hand here i will Quickly supply!

Thank you!!!!

the CPU temps stay around 43c when running prime for 4 hours at 4.1

i did not overclock the CPU/NB frequency, is there a sweet spot for a 4.1Ghz OC on the NB Frequency? i think the last time i did i went to 26 or 2800

Either your board is throttling down the processor (power starvation or VRM overheat), or your overclock is unstable.

I would go for the second.

Set the processor to 3.8GHz, CPU/NB voltage to 1.3V, and the NB to around 2800MHz. Don't forget to keep the HT down to as close to 2GHz as possible.

As for CPU voltage, 1.4V should be plenty for it to be stable at 3.8GHz.

If it improves scores with that, your issue was the overclock itself.

Those guidelines are a base reference that any Thuban processor can meet

By the way, at 4.1GHz with an H60 your processor should be running on the mid-high 50s. 43ºC is simply impossible, that's why I deduce it is throttling due to some factor.

i have set the "auto OC" function, that takes my CPU to 3.8, ill tweak the NB myself since it does not, and ill will get back to you!

TY for the help!

Same CPU as you, getting 7.2k physics.

quite a significant overclock though, I was getting around 6.5k at 4ghz, so something is definitely wrong with your overclock.

Run OCCT as it logs clock speed, or run HWinfo64 while running prime, it will log clock speeds, to check if its throttling down.

On the Thubans, ive found it doesn't like Prime95, as much as OCCT, as some overclocks I've had will run OCCT but not prime95, just my experience..
Plus I like the voltage and temp monitoring in the sensors section also, good little progie
