Left pane, second box down, "PowerPlay" there will be a value for "Max Memory Freq. (MHz)" and whatever value you have in there is the absolute maximum the card will accept.

Question for you iSuX (just cos I think you might have the answer).

I've modded bioses with Polaris 1.6.7 and the One Click Timing Patch, etc. but I have noticed on the 570s that the max freq is 2250, with straps going up to 2000. However, when I try to OC above 2000 it just crashes. Anything 2000 and under runs fine.

So, my question, do I need to be adding extra timings above 2000 to allow it to OC above 2000?

I also see in the memory portion, there are freq and voltages up to 1750 mhz, but nothing above. Should I be adding in more freq/voltage pairs as well? Or is all of this unnecessary?

Hi jeremyismer

...

Happy mining everyone.

Thanks iSuX, I'll have a play when I get a chance. Everything is stable, but I know I should be able to get more out of these cards. But of all the OC tutorials, none mention extra straps. But I know there are bunch of other variables to work on as well (PSU, motherboard (that's a whole other question), mem types)

Hey jeremyismer
TBH, I would not waste time on MB, system ram, or even PSU. (in terms if variables, there is nothing to tune, and little to gain, (assuming you have a stable rig right now)
The key point with PSU is, they are a big portion of your asset cost, so ensuring they run at optimal efficiency vs number of GPU is a quick and easy calculation, that's it, there is nothing else to tune there, no more variables to consider, (other than maintenance and mtbf)

The BIGGEST variable, (loss of income) that I see, is simply this windows update, driver updates, or people's actions, resulting in taking rigs off line.
If you let MS do that, and even if you don't have followup issues, costing more down time, or a nightmare trying to work out what changed, broke etc, but it all adds up to down time.

Latest windows updates, sigh, here we go again, some people are seeing rigs down for hours, only to then limp along for days afterwards, many poor people are still trying to debug their rigs update issues.

Even 3 hours of down time, that is time you NEVER get back. (mining time = money)

Tuning for hash rate increases, now THAT is worth it, even worth the down time, because those small gains will accumulate over time, offset the losses, and increases profit accumulation. (assumes you're mining operations are longer term, (some years).
(more so, if you strategically ensured you have the same make model GPUs, as you can rollout your gains to each one with minimal effort and downtime)

So, imho, the ONLY thing you should focus on is maximising hash rate, to find the optimum power consumption efficiency.

Anything else, anything costing you down time, is time your investment is making no money, in fact it's costing you money to do nothing.

This is more an economics situation than a tech one, assuming you want to earn from it.

Anyway, hope it goes well mate, offer to look at your BIOS remains open.
Cheers
