Question Strange problem when reducing clock speed on GTX560M
Question Strange problem when reducing clock speed on GTX560M
I'm using NvidiaInspector to downclock the card because the memory is failing and everything crashes at stock speeds.
The default memory frequency is 1250 MHZ.
The strange behavior is that when I set the memory speed in the two most performance-focused power modes to about 1050mhz, nvinspector shows a current memory speed of 1103MHZ (a value that still causes artifacts).
If I lower it further to around 1000Mhz or less, nvinspector reports a memory speed of 324MHZ (the third power mode setting), which makes everything much slower.
Why these numbers? Does the card have built-in memory speed modes? Shouldn't it show something closer to 1000MHZ or 1050MHZ as the current speed?
I'm not sure if I explained clearly enough, and I'll add pictures if needed.
Thanks in advance.
