I bought the gigabyte RX 5700 gaming OC variant with a single 8pin and I feel like something isn’t right about its power consumption and voltage behavior. It manages to draw around 220-230 watts at 860mv actual voltage (in HWiNFO) while staying at 1800mhz. I also had to modify SPPT to allow a 50% power limit increase, and 1800@860 is the best result I got with a reasonable enough power draw.
Reaching the stock 1750mhz target clock is impossible with stock 20% limit (204W max), at the same 840~860mv with 204W limit it hovers around 1650mhz under intense load. From all that, I don’t understand how people are running 5700s flashed with XT bios at 1v+ and XT clocks of 1900-2000mhz, because with how ridiculous the power draw of my card is at 850mv, it will probably suck up 300W+ to run 2ghz and/or 1V+. Did I get really unlucky or is this normal behavior for Gigabyte’s 5700 variant? FYI it doesn’t even remotely overheat, hotspot and VRAM are at 80C at 230W sustained. I also can’t really complain about anything else with this card, has none of the common RDNA1 problems, just the VRAM idle clock bug but it’s manageable.
Setup is a little unconventional but it should be good, it ran an OCed Vega 56 with no problems. (Machinist X99 mobo, Xeon E5-1660V4 + 16GB DDR4, MSI A650BN PSU)
