Hi guys,
Specs as follows: 2.8GHz T9600 Duo, 8GB DDR2-800, Quadro NVS 160M, 160GB 7200RPM, A29 BIOS
Basically the issue is that after 10 or 15 useage the CPU bus and multi drastically throttles down as low as 400MHz - temps only need to be in the 60s to do this so it completely needless. GPU temp is 75-85C which seems quite hot with fan on 100% but showing as 0RPM (is it passive?)
There was a documented issue with this back in 2009 which seemed to be related to the integrated Intel Graphics chip and was supposedly fixed with a BIOS update.
However, for mine it worked perfectly for over a year - happily folding away 16+ hours a day on some occasions with no throttling, but over the last month or so it has been getting steadily worse. My first though was dust, so I took the back off and blasted out a few grains but it was pretty clean overall so I don't think that's the issue. I have tried manually setting fan speed to 100% constantly but only buys me a few minutes or so.
There is a lot of material out there with people complaining but none that I can find that solves it (BIOS was fixed circa A19 so I don't think it's that). I was hoping some of you guys may have come across a fix for this or could offer me some pointers.
Thanks in advance!
