Claymore 9 freeze

V9.0 has no stability issues! Your rigs do! Increase GPU voltage or lower clocks!

I'd recommend being very cautious when increasing voltage with V9, given the increased power use from spikes.

Same settings V8 vs V9 on my Fury Nitro (1140/550, -12mv), GPU CORE POWER:

V8: AVG 207W; MAX 274W

V9: AVG 210W; MAX 370W

Only a 3W difference in AVG, but a nearly 100W change in MAX. Big difference to begin with, and enormous in an multi-gpu setup.

(As it stands, undervolting to -96mv and reducing clock to 1110mhz saves me 40W on average V9 vs V8, but the MAX is higher in V9 even when significantly undervolting from V8 (283W vs 280W))

Try mining on pools that support low difficult,

You wont have your cards at full usage at once on high difficult shares,
since low dif you grab and found

You wont have that hardcore mining 100% at time

Ex:

High Dif - 3-5 minutes intensive mining for 1 share - so you have all of your Gpu Full of job for 3-5 minute unstopable

Low Dif  5-15 seconds quick mining for 1 share - Grab and Send, you wont have full usage 100% of time

It is just a theory but i think it is valid

 V9 has some MAJOR stability issues for at least some configurations.

 I tried lowering clocks on the 7870 test rig I DOCUMENTED my issues with during fairly extensive testing in the main CLaymore V9 thread - doing so made NO change even when I got the card down to about 200 Mhz UNDERclock on core and 300 on mem (afterburner limits for that card) the ONLY change was that the hashrates reported got lower than what I reported in that thread.

 I can't increase voltages as they're locked on that card (and they're at stock anyway).


 Same card was highly stable back in the days I used it on Scrypt mining, and for all the MooWrapper/Dnet work I did between it's Scrypt days and it's ETH/ZEC days - both of those drove that card a LOT harder than ETH or ZEC do (as measured by the MUCH HIGHER POWER DRAW and higher operating temp at higher fan settings in both cases).


 I've never played with the BIOS on that card in any way, so it's not a "bios issue".

Intensity 2 it is very stable for me on rig that are freezing

has v9 killed anyones card or rendered them temporarily (a few reboots) comatose?

are the spikes in power sync'd with the "donation" portion of the mining?

I'm running 6 cards (r9 380) with zalman 1250w platinum and other 3 cards ( r9 280x, 280 and 7950) with super flower 850w ( golden green)  with no problems.

None of my cards were killed.
