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 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 Before After

I decided to remove the PSU from inside the case. The airflow improved resulting in lower temperature. 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

Can you make a binary only to test with up to 5% HW rate? I don't get it cross compiled... ...can not find curses.h or ...../mips-openwrt-linux-uclibc/bin/ld: cannot find -lcurl

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
