The overclocking blew out my power supply. My "silver" unit had an Antec Green 650W power supply. I ran to the store and they had a Corsair 800W and I got it working again.
was it easy enough to upgrade the PSU? I have 3 corsair 860w platinum arriving later this week It is easy ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Just remember to slide cut out cardboard to hold the screws in place. You can see photos of me using this on my power supply swap out that I had posted. Here is a before and after upgrade to a Corsair AX860i from the original Batch 1 Avalon power supply. https://bitcointalk.org/index.php?topic=156323.msg1910169#msg1910169Side by Side ComparisonTypical Batch 1 Avalon before upgrade, and an upgraded Batch 1 Avalon ![](https://ip.bitcointalk.org/?u=https%3A%2F%2Fi.imgur.com%2FUy4nITF.jpg&t=663&c=Nlvptju3zTLweg) Before After

I decided to remove the PSU from inside the case. The airflow improved resulting in lower temperature. ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) letting hot air out with decreased air presure may turn out to be better.

I am considering on getting the Corsair AX1200i in an attempt to push the system into the 400s. Because of its size I will have to keep it outside the case.

In the current heat wave where I am, my Avalon is pulling about 780 watts from the wall. I'd go with something bigger than 750 watts.

[timeout] => 33 [frequency] => 354
I think the timeout is to low. With 365 i had to change timeout to 36 to avoid restarts.
36 will be generating dupes. Check your rejects

My 2 avalons sitting at 355/352. Temps 35/41 and 35/39 --avalon-temp 40
With strombom firmware they run @365 86.9 GH after 20h
With strombom they run your fans at 100%. You can achieve the same fanspeed with my firmware by using --avalon-temp 0

Hi. I've uploaded a new firmware with the about-to-be-released cgminer 3.3.1 with 2 new features which I hope you'll like: http://ck.kolivas.org/apps/cgminer/avalon/20130626/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin--avalon-auto Adjust avalon overclock frequency dynamically for best hashrate --avalon-cutoff <arg> Set avalon overheat cut off temperature (default: 60) this is in addition to the existing options: --avalon-options <arg> Set avalon options baud:miners:asic:timeout:freq --avalon-temp <arg> Set avalon target temperature (default: 50) I flashed my Batch 2 with this and now I cant connect. What's the IP ?

It seems that only one of my Avalons benefits from the new automatic clock adjustment option. The other two decrease such that setting them at a set, higher point yields obviously better results - at least based on the "MHSav" reading.

testing ckolivas auto feature now -> very nice
ATX: Corsair AX860
speed Mhz power @wall @230V 300 595 Watt 310 610 320 630 330 650 341 670 seems to stop @ this frequency?
giving me additional 6-7 GHs
fans are heavily circulating from min to around 3400 rpm when i set target-temp to 48 degrees they are influencing power draw above values are taken @min speed high speed will draw about +15W
will try agin with default temp;)
donated 1BTC to ckolivas 7a398e9723d533dfc13d99ec44e040645704f939e037851a84cddc430dab0d00-000
rpm starts a min raises to over 3000rpm when target-temp is hit and then slowing down to min step by step seems not the optimal strategy - I think better raise fans slowly before target is hit
@ckolivas and if I'm allowed to express a wish: 40% fanspeed as min also will be fine for me;) or also configurable as knows from gpus..
great job!!! go on
