Can I overclock GTX 680?
Can I overclock GTX 680?
The GTX 680 Classified is first and foremost an overclocking card, and while EVGA ships it with a decent factory overclock it’s the end-user overclock that is going to make the GTX 680 Classified stand apart from the crowd.
Can you overclock a GTX 660?
In its rawest form, GTX 660 will have two things going against it for overclocking. Memory overclocking is as volatile as ever, with a 400MHz spread between our best and worst cards. Again with the use of the reference PCB (and the same Samsung RAM), memory overclocking is entirely the luck of the draw.
Is overclocking the GeForce GTX 680 worth the risk?
We just reviewed the GeForce GTX 680. And though we briefly touched to topic of overclocking in our reference article there’s still one bit missing; extended tweaking performance. Overclocking never comes without risk, but it sure as heck is interesting to see how far you can take a card.
Is 6-pin power supply enough for a GTX 680?
The GTX 680 has a lower TDP than monsters like GTX 480 or 580, so 6-pin is usually enough for most overclocking conditions, even on water or subzero. The memory VRM is similar to one used since GTX 480, two phase with discrete FETs.
How much should I overclock my GPU and memory?
In the first stage you overclock your GPU, in the second the memory. Once you get artifacts or a lockup, back down 25 to 50 MHz and typically that is your stable result in it’s highest threshold — under the condition that the room temperature is the same (yes heat and surrounding heat have an influence on your overclock).
How many phases of VRM does the GTX 680 support?
The main VRM is made to support 5 phases, but final reference boards were de-featured to 4 phases, which is enough for air cooling. The GTX 680 also uses input power sensing circuitry to calculate input power and adjust it’s speed and voltage to meet the desired performance and power limits.
