Somebody was asking here a couple days ago wether Sapphire was a reputable brand. All I can say is hell yeah.

After playing around with undervolting for maximum efficiency I wanted to see how far I could push my card. Here's my findings:

• Model: Sapphire Nitro RX Vega 64 (11275-03-40G, Samsung HBM2)
• BIOS used (240W stock power limit, original BIOS here)
• Settings used (stable!)

Results:

• Clocks: around 1700Mhz (1685-1711)
• Temps: max 71°C@2000rpm Fans ( 33% from stock)
• Power draw: max 336W
• 3DMark Firestrike: 20013

Now there are 5 results on the site with the same CPU (2600x) and single GPU that have higher overall scores, but thats due to better CPU performance in the physics test (higher max boost [How'd you do that?!] or all-core overclocks. My pure graphics score is 100 points higher than the best result there.

Has anyone been able to push a Vega 64 on air any further? Whats you settings?
