Core/Memory Clock Power Consumption

post #1 of 8
Thread Starter 
So I've got a reference GTX 780 that over clocks quite well.

The memory clock stably runs at 7GHz and can go much higher. The core clock runs at 1.22 GHz and could go higher but keeps running into the 107% power constraint and throttles down.

If I lower my memory clock, would it "free up" more power for the core clock to run at higher clock speeds for longer?

Thanks.

Can you increase the power limit?

It's been increased to the maximum that NVIDIA allows - 106%.

Reduce the vcore and voltage and would stop throttling.

Otherwise in nvidia forum there is a guy which says that can edit your bios and increase the limit for the power limit(tdp) bar

Temperatures don't appear to be the cause for throttling - it tops out at around 72C. Besides, lowering the voltages results in instability.

If I didn't want to go the BIOS route, would lowering the memory clocks help out with overall power consumption?

Thanks.

Memory if you didnt modify its voltage then You should downclock the gpu and the vcore.memory doesnt use that much energy as the core/gpu


Ad throttling is also presebt for a Low/limited TDP(which can be changed through the power limit)so having a bigger power limit should fix the throttling

Did NVIDIA specifically pick those power limits to prevent damage to the power regulatory circuits? Would there be any harm in increasing power as long as it remained cool enough?

Well mayne if it`s a reference design would lack of enough vrm to hold a higher TDP.but if the card is non reference could have a bit more power phases.
But come on always brands put limits to be in their "safe zone"


I would ask on the 780gtx thread
