Most Favorable Review

Must be minimally tweaked to (decrease heat, power consumption & throttling ) at same stock speed

SAPPHIRE Radeon RX Vega 64 8GB HBM2 PCI Express 3.0 CrossFireX Support Video Card 21275-03-20G
SAPPHIRE Radeon RX Vega 64 8GB HBM2 PCI Express 3.0 CrossFireX Support Video Card 21275-03-20G

Pros: - Powerfull GPU at 1440p gaming. I get 60-90 fps on multiple recent highly GPU intensive games at max settings. - Amazing Sapphire build quality with my old and new GPUs, never needed once to contact support in 5 years. - Great GPU management utility (Radeon Wattman) controlling clock speeds, voltage, temps, fan speed and monitoring GPU performance. - AMD drivers has gotten immensely better in stability and in frequency in the past 2 years. - Blower design is great for crossfire setups - Overclocking HBM memory speed will result in a noticable performance boost, just as overclocking frequency.

Cons: - Minimal tweaking is required from the user to run the card at the same stock speeds but less power consumption, heat & throttling. - On stock, it has high voltage, runs hot & throttles without minimal adjustments. - On stock, the card is power hungry. - On Stock, its max fan speed without minimal adjustment is 2400rpm & its target temperature for the fans is 75C. - 3rd party apps for voltage, clocks & fan speeds conflicts with Radeon Wattman & cause issues.

Overall Review: **READ ONLINE ABOUT UNDERVOLTING** I've only adjusted the Voltage control. Same stock clock speeds but now with lower power consumption + better cooling + less thermal throttling + increased performance gains. Had this GPU for about a year and a half. I bought a 2nd one recently for crossfire. Here are my Wattman settings: (GPU) State 6: - Frequency: 1537mhz (stock) - Voltage Control: 950mV (adjusted from auto) State 7: - Frequency: 1632mhz (stock) - Voltage Control: 1000mV (adjusted from auto) (HBM MEMORY) State 3: - Frequency: 945mhz (stock - can be bumped to 990mhz easy without issues) - Voltage control: 950mV (adjusted from auto) (FAN) - Manual (Min 400, Target Max 3200) (TEMPERATURE) - Max 80c (this is your max requested temp before the card will start throttling big) - Target 70c (this is when your max requested fan speed kicks in) - Power limit +50%
