Correct Overclock for RX 470/570?

Radeon Crimson
RX 470/570 with Themartake 650 Smart Bronce
RX 470/580 with Sentey Stell Nitro Power 550 White
(are 2 PCS)


Hello, i have 2 RX 470 and 2 RX 570. and i want OC this cards (the amount in USD is awesome superior, about 30% per card). But... the wires of my powersuply come hotter, and the temperature of cards is very higher.

For example:

Without OC:
1700 memory clock and 0.6 USD, Temp: 69%

With OC:
2200 Memory clock and 1 USD, Temp 89%

The real problem isnt the temp, becouse i can put a external fan. But the energy consumition will be higher

Also, i dont want kill my powersuply.

Finally, i want know a correct and good Overclocking config for this, for:

High Money, High temperature, Normal energy consumition in month

Currently, i am thus:

Very high diference to earned money, but extreme consumition energy and xtreme high temperature and maybe FATAL use of my cards.


So, what can i do for this? I am sure of touch only the memory clock

Turn the power down on your overclock.  15% or so, there will be a sweet spot ratio of power draw per hash on damn near every individual card if you really want to dial it in.

I've never gotten a 470 or 570 to run stable (i.e. weeks) at 2200 memory clock...I dont think I've ever gotten one to run at 2200 without immediately crashing the GPU driver.  I have most of mine around 1950.  I probably lost the silicon lottery on all of them.

Turn down the core clock on ethash...1100 or so, less if they stay stable. 

On the PSU: Dont run it at > 80%.  For the PCIE cables, Dont run more than 280 watts on a single wire (470/570 should stay under 140 watts easily on ethash or CN).  Avoid pushing any of those limits. 

Dont run more than one riser per SATA wire.

Hey, the "hot wires" alone is a very bad sign of extremely high current running through those wires.
You might wanna manage the PSU cables just like Harai Goshi said, or else, it will burn (literally).

Very high diference to earned money, but extreme consumition energy and xtreme high temperature and maybe FATAL use of my cards.

Extra heat is common for overclocking since you're feeding the cards more power than usual but...
It's not that "FATAL" for your GPUs as long as your cooling system is at best, if it's stable: it's good; but also...
You've mentioned that the temps are too high, so you might needed a better cooling solution to lessen the strain to your GPUs if you want to push OC~ing.

For which algo? Which driver version your are using? Temp is no problem if you lower the voltage, then power consumption is no problem too. They are so many descriptions put there, please use search or google.

For downvolt I use WattTool.
Voltage can be lowered to 0.9V
It is approximately, each GPU is individual.

You should write exact model of your gpus (manufacturer, ram provider of your gpus like hynix, samsung, etc), algo you are mining... Optimal overclock settings are different for algo/gpu
