Lasse(@lasse_ai):How much performance do you actually lose when capping a DGX Spark and where are the sweet spots? As a follow-up to a previous post I decided to test it using my 2 x Sparks and likely the best model and quant currently available @MiaAI_lab's Deepseek V4.1 1017 EXL3. Depending on your preference the sweet spots are 2200 MHz for close to original performance or 1900 MHz if you seriously want to reduce Temperatures and power consumption. Anything below 1900 MHz and the Sparks start fighting with themselves.
