Yeah Achim I want him to make the source code available or just edit it himself to add MSR values.

PSU: Picking it up tomorrow. Would be good if you had one to compare if we both pull different currents/watts for the same volts/settings.

CnQ: If I change values whilst having CnQ enabled (through Windows+BIOS), CnQ doesn't fully kick in until I disable it within Windows and then enable it again. Loses me 3-5W AC idling.

As you know, I've found I'm still stable at lowish volts for 204x13x9x9x2.66, 94W AC idling now writing this and having at least 11 other apps open. Still at the same volts you can see in my 3DMark06 run I posted in the MSI thread. It's been running for over 35 hours now at this setting, many reboots etc, but hardly any downtime. I'll move it up slowly, testing all CPU/IMC/HT/RAM for instability is a bit of a long winded hassle.

Well, found the WinRing0 library (http://openlibsys.org/manual/), should not be too difficult to write such an app with that lib.

Just ordered one, p-tune looks promising. Hope i can run the monitoring stuff on a different pc (assuming it connects via usb or similar).

I think this is normal behaviour, if the p-state changes the register get's copied to c0010070. Here it was enough to generate some load start/stop prime95 to force the switch.

Must say i'm ok with 2.6GHz at 1,3375V (1,325V just froze). Max i got stable for more that 4hrs is 2.63GHz(~1,39375V). 2.64GHz freezes after ~half an hour with volts up to 1,45V, which is too much for me to run 24/7.
Can not get my idle consumption below 105W AC.

Visual C++ Express makes his way to my laptop atm. Already installed it on my phenom system and was able to build the OpenLibSys DLL. Samples require MFC so i can't build em with the express edition.
Never wrote a windows app in c++, gonna skim over a few tutorials first. Should not be too difficult.

Hehe, excellent find. It makes it look so easy Need to remove a ")" from the end of that link to make it functional.

Not sure what you mean, but if you mean the PSU is used and monitoring one system while you're logged on another and seeing the metrics with the software, then I'm not sure.

Yep. But in my case, total P-State change didn't occur even if it was copied to c0010070 and c0010065 and c0010062 set to P1 unless I enabled and disabled CnQ again.

Wow, things are a little different but my volts are lower so that's why. I had to increase volts to get more stability but no need to increase IMC/NB/HT/RAM volts yet. I'm at this since around 12 hours now for stability:



One notch less in volts (1.264) would fail on core3 after 30 mins while other carried on past 4 hours smallFFT.

CnQ Power: Idle 93W AC
No CnQ Power: Idle 105W AC

It's getting better with optimizations, pretty weird.

Yea I don't like clogging my drives up with big software etc, not even got word/etc installed on these. Only the basics. IMO writing C++ is boring but that's not the worst bit, deassembling them is the biggest pain.

BTW, Sapphire board I may skip testing. I'm too short of time and got the Abit 770 and GBT 780G as well to test yet.

It is easy to use if you are familar with c no cryptic c++ inside.
THX link fixed.

Ah ok, that makes a difference. Noticed here that without phenom drivers installed only the multi changes and the vid stays.

1,3375 CPU VID froze in the morning exactly as i powered on the monitor and tried to move the mouse. 1,35V froze after a few minutes, had it stable at that voltage for 10hrs already. Restored my save 2.5GHz settings (higher nb and chipset voltages and mem in 800 mode).
p-state tweaking does not help in stability here, maybe if i also touch idd stuff. But it saves ~30W AC here, lot more than on your system. Also the system is still pretty snappy at 800MHz for normal tasks

Hope i can port that stuff to msys or cygwin once i'm finished.

No big deal, with that PSu we can use the exact same testing setup's, so no need to do everything twice.
Those 780G boards are only listed at a few sites but not jet at stock here. Hope I can get the J&W RS780UVD or something similar with side port memory.
