Polaris Bios Editing ( RX5xx / RX4xx ) - Page 151

A little mod to the stock cooler


+50% Power - 1350Mhz@1131mv - 3000Rpm Fan - 75°C in TW3. Little to no throttling
post #1502 of 3400
Nice cooler mod. I've tried this and the fan just spits air in all directions. Amazing your temps are low. Maybe it likes it like that?

Anyway, just wanted to let anyone know I finally figured out how to set the fan so it actually keeps the card cooler.

These settings keeps the RX 460 at 63C constantly, about 39-44% fan speed. It's quiet/ cool/ faster/ and more stable than the standard profile.

Max Temp. : 88C
Shutdown Temp. : 88C
Hotspot Temp. : 88C

Temp. Hysteresis : 16 (It appears to dislike 0, so I set 16 so it's more gradual and less noticeable to the ear)
Min Temp. : 34C (Begins to spin earlier)
Med Temp : 54C (Closer to Min & High)
High Temp : 64C (For this card, this is an ideal number/ keeping in mind real VRM temperature)
Max Temp : 88C
Min PWM : 20%
Med PWM : 67% (Keep Med/ High Same Value Less Or More)
High PWM : 67% (Keep Med/ High Same Value Less Or More)
Max PWM : 88% (100% is too noisy for this card XFX DD)
Max RPM : 3333 (Less than default 3800)
Sensitivity : 3333 (Less than default 4836)
Acoustic Limit : 0 (0 so it actually cools the card)

Anyone that has experience with the RX 470 Strix, has the 6-pin PCI-e power been a problem with increasing clocks/voltage? This card is notorious for throttling, with the 60c thermal limit from the factory. I can't help but wonder if that is simply a roundabout protection mechanism to prevent the card from drawing past the PCI-e power specs? Most all other 470's have 8-pin power, and have no incessant throttling behavior.

So, assuming one edits the BIOS for higher thermals and increased power, is it all for naught due to the technical 150w power draw cap? Is the 470 Strix just best to undervolt and set at 1200 MHz max and call it a day?

True, with 8 pin PCI-e I'd have no problem increasing the power limit. Looking at reviews of the 8 pin 470's, they pull far more than the 120w AMD states as the reference for the 470, and a bit more than the 150w that the Asus Strix 470 would theoretically max out at. The Strix itself is bumping right up against the 150w PCI-SIG spec, so it seems Asus should have gone 8 pin as well. Best hope for the Strix looks to be in obtaining one with high ASIC, undervolting, pushing thermal/power limit up, and pushing clocks as high as vcore will allow.

maybe i can run my 480 on 1050@1300 stable drops my temps quite a bit at lower fan speeds.

I have seen reference 480s clocked at 1500mhz. Probably in the 230-250w territory. I don't think the 6 pin is a big limitation.

Impressive speeds for the voltage. Got a deal for a Strix 470 that I couldn't resist, so will be exploring clocks and BIOS over next few days.

Official PCI-SIG specs state 16x slot delivers 75w, 6-pin delivers 75w, so a total of 150w. 8 pin is 150w, so hoping you're right that the 6 pin won't be a hindrance.



On separate note, what driver version delivers best performance with these cards?

I looked back at the OP and do not see anything about BIOS's that are saved as 256kb from ATIFlash. Can these be used by Polaris BIOS Editor and then successfully flashed?

Ah, it does work.

256kb bios

hi all, new here! I got the gigabyte rx470 gaming g1 4gb (hynix) a while ago, and would like to run the card at lower voltages.. does anyone here have any luck with it? thanks!
