In Reply to: RE: 840 MHz... ;-) posted by Bertel on June 15, 2009 at 12:09:52
Lower CPU frequency allows for lowering CPU VID. In my setup, I have VID @ 0.73750V (one notch lower than before). At this level, CPU temperature (at max load) as measured in BIOS is 35°C and through RealTemp its 46°C/45°C (core 0/core 1).
No, sorry, I have to correct my yesterday's post - a cold boot (system was off overnight) is still not possible with VID values below 0.76875, even with CPU Host frequency now at 140 MHz.
When doing a cold boot before, the system as kind of "standard procedure" always had failed to come up at 900MHz so BIOS always reverted CPU Host Clock Control to "Disabled", System Memory Multiplier to "Auto" and DRAM Timing Selectable to "Auto", which I then always reset to "Enabled", "2.00" and "Manual". A warm reboot was always possible without that procedure if the system hadn't been idle too long (~5-10mins).
So it really seems I can't get any lower than 0,76875V. I would have loved to do so though, since every notch or two down brought what I considered still another (although small) improvement in relaxed audio reproduction with a tad more transparency and less distortion.
Or did I miss something?
