(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.
