Overclocking the RX 470

[CornBreadMan]

Oh boy, this is a weird card to overclock. Usually you would increase the voltage right? Wrong lol, it seems like with the Polaris cards in general, under volting is better. Look at Reddit. I'm using Firestrike for my tests.

i5 4590
16GB DDR3 1600
AsRock H97 Pro4
EVGA Supernova 650W 80+ Gold
Sapphire 4GB RX 470

I'm using WattMan.

Oh, keep in mind my Physics score is always around 6600, no there is nothing bottlenecking that, look at Physics scores for my CPU on google lol. Always around 6600.

So at stock clocks and voltages (1260 core @1.150V, 7000 memory @1.000V, mine is factory overclocked)
I get a Overall score of 9117, Graphics score of 11786, combined score of 4197.

The best score i've gotten that I can actually replicate is 9476 Overall, 12480 Graphics, 4425 combined. And that was at 1360 core @1.120, 1750 memory @ .97. Can I go higher with my core? Yes, but my score gets lower. I can get up to 1380 without increasing the voltage past its stock setting.

And no, CPU never overheats, GPU never goes past 73, I don't even have an aggressive fan curve on it either, its on auto. And wattage wise, according to GPUZ, the highest i've seen it get up to is 152 watts.

Can somebody better then me help me with this?

Okay, did 1350 @1.115, memory 1750 @.98 and got a Overall of 9519, Graphics of 12414, Combined of 4439. Weird card.

When AMD started calling the 7xx series R9 2xx cards, they started very aggressively clocking the cards "in the box"... as a result, overclocking once out of the box, was very limited. The R9 3xx AIB cards were limited to 6 - 8%.... The AIB 480s, best I have seen other than the MSI card was Asus 6%.

The Asus 470 managed a 12% fps increase...topping out with core clock of 1360 MHz and memory clock of 1910 MHz

SOunds like you may have hit the lottery with the chip you received in your card😉 The settings they programmed in may be higher (voltage wise) than you need, have come across some cards like that

 

[CornBreadMan]

I guess they clock them high out of the box to keep them on par with Nvidia?

 

[Tradesman1]

They try 😉 nVidia cards are often OCed by the manufacturers of the cards also...AMD is and has been a bit behind nVidia in GPUs for awhile now just as they are with being behind Intel (again for some time now)...Where nVidia moves ahead, AMD tends to to continue to recycle their old tech and push it further, add more DRAM, and gimmicky things. The biggie with them now is Zen and hopefully it will be a nice jump, but not counting on it

I don't find it wierd that you can get better after raisin clocks and lowering voltage. Sounds exactly like a cpu OC to me. You get cpus/gpus with voltages set high, just to cover any actual chips needs without diving into every single chip made. I think it's entirely possible that your upgraded clocks with factory voltage could be driving the VRM's too hard and the card is throttling back a small amount, lowering the voltage would be setting them free to full power.

Wow, somebody messed up the voltages. I don't know if its software or hardware, but somebody messed up.
I basically copied this guy: https://www.reddit.com/r/Amd/comments/4qtuu5/rx_480_undervolt_oc_1340mhz/
I'm at 1350 @1.1V, tried 1.09V like he did but then green flashes appeared. Then its 1825 memory at the same voltage as him. I could probably go higher, but nah, too much work. Got 9557 in Firestrike, 12597 Graphics, 4473 combined.

My MSI gaming x rx 470 4gb is running 1400mhz @ 1175 volts and 1900mhz on the memory at 1000 volts on wattman completly stable and never going over 66 C° while the fans max out at 70% my asic score is 91.2%. I could probably push it further but why bother when im happy with what i have.

Could you upload a pic of your wattman config?
