Re: How to downgrade 3770 to 3770s.

Re: Underclock

Prime95 is for stress testing. In sandy bridge every CPU ratio(multiplier x 100= CPU frequency) has certain factory voltage (SVID) associated with it and for number of cores activated. It adjusts CPU multiplier depending how much work needs to be done. But you don't need to know that, just enter the...

Re: Underclock

The CPU Voltage drops with the Ratio. The lower you set the CPU ratio in the bios, the lower is the voltage. For example Dual-Core Sandy bridge has CPU package power consumption of 25 watts @ 2.5Ghz 1.05V under Prime95 Load. Passive cooling should be possible in some cases, assuming it will never re...

That will likely refer to the fact that you can adjust the multiplier DOWNWARDS in the BIOS. There is a lot of cut and past and ambiguity in manuals at times so better to rely on the hands on reports. That doesn't make sense since the manual states the multiplier depends on CPU used.

Yes of course, it is in fact the end, and it is the checksum:o
Mine stays to 20% upto 60C, then ramps up, to reach 72C and 50%
I guess there could be set less than 80%, for different ramp, whatever logic works.

875K is likely the last of the 1156, no 32nm down the road, just big hot chips based on 3 year old 45nm process. As for 1155 it will support maybe even 22nm in 2011-2012, just before DDR4 changes the socket in 2012. By the time of 22nm, the old 45 will be full stop, so is the 1156.

During summer, 86F room temperature the VX450 starts to ramp up the FAN rpm at 150W AC / 125W DC power as opposed to 300W AC at 66F.

I guess it doesn't get that hot at your location though.

VX450 can even handle 44A wich is crazy, efficiency suffers. That is why they labelled it 450W instead of 550.
