Some examples of working with Nick and my wx 4150 mxm card (note in xserve3,1).
example of the loop to check ioreg (without fan speeds since mxm has no fans)
Code:
$ while sleep 2; do ioreg -l |grep \"PerformanceStatistics\" | cut -d '{' -f 2 | tr '|' ',' | tr -d '}' | tr ',' '\n'|grep 'Temp\|Clock'; done|paste - - -
"Core Clock(MHz)"=1016 "Memory Clock(MHz)"=300 "Temperature(C)"=63
"Core Clock(MHz)"=964 "Memory Clock(MHz)"=1500 "Temperature(C)"=63
"Core Clock(MHz)"=998 "Memory Clock(MHz)"=1500 "Temperature(C)"=63
"Core Clock(MHz)"=1025 "Memory Clock(MHz)"=1500 "Temperature(C)"=63
"Core Clock(MHz)"=1008 "Memory Clock(MHz)"=1500 "Temperature(C)"=63
Tried a few of his roms, some of which resulted in GPU clock being stuck at 214MHz (original rom idle speed was 300MHz) but Memory was able to hit 1750MHz (vs previous cap of 1500MHz) this of course killed metal bench back to 4k from nearly 14k.
Found windows compute numbers for the WX 4150 ... seems they have OpenCL around 15k-17k, so getting 13k/14k seems like a decent number considering 2x PCIe bus and a slow E5520 2.2Ghz CPU
Based on all of that i'd believe that it may get truly stuck at 300MHz depending on what was tweaked / not loaded properly.
Thanks!
