So how hot is too hot?
I'm running my batch 1 and batch 2 units at 350MHz now. B1 seems to have settled on 47c for temp3, where B2 is at 52c now. Ambient temperature here is somewhat high (28c).
I have to place my unit right at the mouth of AC vent to make sure temp3 < 50C. In SW USA, top floor

If anyone is interested in power consumption of the different clocks: 300: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fcontent.wuala.com%2Fcontents%2Febereon%2FShared%2Fbitcoin%2Favalon%2Fstromverbrauch_300MH.JPG&t=665&c=-VR-YoRpNnXrGw) 325: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fcontent.wuala.com%2Fcontents%2Febereon%2FShared%2Fbitcoin%2Favalon%2Fstromverbrauch_325MH.JPG&t=665&c=ZqrT8QXqMunn3Q) 350: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fcontent.wuala.com%2Fcontents%2Febereon%2FShared%2Fbitcoin%2Favalon%2Fstromverbrauch_350MH.JPG&t=665&c=mr_yF7XZPR7UvQ) 375: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fcontent.wuala.com%2Fcontents%2Febereon%2FShared%2Fbitcoin%2Favalon%2Fstromverbrauch_375MH.JPG&t=665&c=NkbH6IBm0pFmfw) I think this is very acurate ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) greets, ebereon

ebereon, Great post about power!
What about hash rate at 375? I am afraid to test it and as reported there is no big increase performance

Is the measured consumption for 3 or 4 module Avalon? And what should be the recommended PSU wattage for 350 Mhz and 4 modules?

Thanks! As you can see, I had it running only 1 minute. It had 180HW errors and ~15 shares. The hashrate was ~76GH... very bad and not healty. Is the measured consumption for 3 or 4 module Avalon? And what should be the recommended PSU wattage for 350 Mhz and 4 modules?
This is for 3 module avalon batch#2 black (stock 750W PSU). Just calculate the Wattage for 3 module to 1 and you know what it will be for 4 module ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

There is 14% reserve, so that should be OK. But it depends on quality of PSU.

I think 750W is output power of the PSU. Should be ~900W@Wall. At the moment I calculate 720W@Wall with ~80% effiziency = 576W PSU output. Thats fine I think.

I haven't realized you measured it on the PSU input. My mistake.

The power consumption depends a lot on ambient temperature. My stock PSU consumes 850W at night and 950W during the day. Upgraded to the Seasonic X-650 Gold 750W, and day power consumption reduced to 870W. All at 350MHz. http://www.newegg.com/Product/Product.aspx?Item=N82E16817151087

I am interested as well. These look like they can reach 4000rpm max. Will buy a couple in case one fails.
