1045T super energy efficient

post #1 of 17
Thread Starter 
Running a x6 1045T in a Asus M5A97 mobo. Since this is my virtualized file server, I'd like to make as energy efficient as possible. I was thinking about disabling 2 or 4 cores and undervolting. I know this is exactly the opposite what people are trying to do on OCN.

Anyway I was thinking instead of spending more money to buy a energy efficient CPU, I'll just dial this one down, you guys think that makes sense, and do you guys have any suggestions or guidelines on what kind of voltage the 1045T might need for 2 or 4 cores running?

You can dial it down. and if you end up needing more you have room to grow

Just give it a shot. Disable 4 cores and underclock it.
post #4 of 17
You won't get it down as low as a true low-power chip, but being as you already have the setup, I think it's worth doing what you propose.

According to Tom's, disabling more than 2 cores won't help to reduce idle power:
http://www.tomshardware.com/reviews/phenom-ii-x6-thuban-core-scaling,2652-10.html

Simply underclocking won't save you very much power... most of the power reduction will come from undervolting.

I suggest disabling just 2 cores, then as a quad, underclock down to where you want it, then undervolt down in steps until you find out how much voltage you actually need.

First of all, make sure it has a rubbish GPU, Set the clock to stock, under volt it a little, make sure Cool n Quiet is enabled and C1E, undervolt the CPU/NB a bit, set all voltages to stock, set memory voltage to stock.

Download K10STAT and set custom Cool n Quiet voltages and tada!!

Iv'e done it with mine, the lowest my computer has pulled from the wall is 86 Watts at idle, that was when my GPU was in Zerocore mode also.

If you underclock the CPU to something like 1.8~GHz, you can probably run around the 1.0v area. Disable 2 of the cores as well to help save a tiny bit of power, no need for a 6 core file server in home use. A slight underclock and undervolt to the NB core in the CPU will help a bit too, and if you loosen your RAM timings by maybe 1 step you may be able to undervolt the RAM a little bit too. With the C states active during idle it is possible that you *may* get the idle draw down below 75w. I just built two new computer that used Trinity processor (ya I know, entirely different CPU) and was able to get idle drain down to 30w for the entire system.

Got my quad core down to 1.2V a few weeks ago at 2GHz, ran fine and was perfectly stable, probably could of got it lower but didn't really try, was just curious to see how it would perform @2GHz and with an undervolt, considering it was coming from 3.6GHz I probably would of got it down from the 1.34-5+ down to 1.1V or something around there.

I suggest disabling 2 cores, underclocking to 2GHz or as EniGma said "1.8GHz".
After that commence the undervolting down to 0.1V below and keep reducing it and running a stability testing program until you are happy with the stability, power draw and performance!
Who knows, you may even be able to keep the six cores and just undervolt and underclock it but single threaded applications will probably take a massive hit unfortunately due to the low clockspeed but you'll only know if you give it a try!

Enjoy!

Have you got all Six cores running still?

I did yes, disabling 2 cores on my X6 barely made any difference, maybe about 2-4 watts less at idle but it pulled less at full load compare to having all 6 enabled though.

Disabling 2 won't help you much in idle, but it will help when your server / HTPC is running background checks (Anti-Virus for example)

If anyone needs any more help on making your X6 or X4 more energy efficient, post here or PM me thumb.gif
