Am I allowed to put AntMiner S7's frequency on 1000 at good temperature ?

[sam-j]

Hot summer is near and I need to turn on the airconditioner exactly in front of the antminer, So the airconditioner could cool down the antminer and drop it's tempeture and take it to about 50C(frequncy is on defulat, 700, batch9).

With this tempetrue (50C) Am I allowed to put the frequncy on 1000 ? Is there any risk of hardware damage ?

Is that worth the electricity if you already need an airconditioner to cool it down?

[sam-j]

We need airconditioner to cool down ourselves air tempeture comes near 60C here. airconditioner need to be on 24/7 or we will burn in this hell

Quite apart from the cost side of things I do not think you will ba able to run an S7 successfully  at 1000MHz?

Will also depend on which Batch you have? Assuming it is one of the later 135 Chip systems I think the very highest you might go to is 900MHz and you would need to monitor the Temperatures carefully and would  probably be taking close to 2KW at the wall.

okay  here is what you do.

run ac right into the intake

make sure the fan that blows the air outward is not restricted. So make sure the exhaust is vented out of the room.


Step one

set freq to 700 fan to 70% make sure the psu has 12.5 volts not 12.0 volts


Step 2 fire it up
run it for an hour
check temps  should be 50c or less
check fan speed  should be 4200 to 4600
check errors       should be 0.0025 or less

step 3 jump freq to 725   fan to 70% make sure psu has 12.5 volts not 12.0 volts

step 4
run it for an hour
check temps should be 55c or less
check fan speed should 4200 to 4600
check errors should be 0.0030 or less


keep that pattern of increase.

when temps reach 62c stop
if temps stay under 62 c  and errors get to  0.200 stop

a fan setting of 100% is not necessary   top rpms are about  4200 to 4600
you will get them at 70 to 75% fan setting

I have never seen an s-7 get past freq 800   so good luck at doing better then that

Start by learning some basic electronics. It is dangerous if you don't exactly know what you are doing.
