Really interesting. I have 4 in my office with the window cracked, super cold in there. With the core voltage a .819 I'm able to run them stable at 832. <.5% errors. I have not touched the memory voltage.
Increasing the speed certainly ups the error rate. Is anything under <2% really optimal? I want to see it at close to 0 as possible, maybe that is silly, I feel satisfied at<.5%. I start to worry over 1%.
My tinkering has been minimal, but as an example if I go to a speed of 852 error rate is ~1.2%, and increasing voltage does not seem to help, maybe it just creates more heat, or my increase is too much?
Not trying to be greedy, 4.7mhz is pretty good, but I was hoping to get to 5mhz, so I'm curious how you guys nudged your speeds up.
What are your voltages?
Impressive....are you running at max frequency? Do you have core voltage maxed out as well?
No way he's running max clocks AND maxed voltage...regulator would definitely blow up or shut down due to over-current protection. Definitely don't recommend running these at max clock, but running one of these at max clock this stable is impressive...8 all one the same hub...thats crazy!
Hey, @jstephanop,
you made this awesome stuff! I am running 6 mlds at 924Hz (plus 5 at 824Mhz) all on the same hub,
with the pots tweaked down as per your instructions, my HW rate is a little higher, at .9% and my hashrate it a bit lower, at 5.3Mhz/unit, instead of just over 5.4Mh/s as with @dem0nlord. Been running stable without restarts for weeks now. I got (borrowed) an IR temp meter, the 824Mhz MLDs I am running without stockfan and they are at ca 44degC, the 924Mhz I am running with stockfan, and they are about the same.
