3820 overclocked to 4.825 doesnt really downclock when idle

I cant seem to get my 3820 to downclock significantly when idle. In the attached screenshot, it goes down to 3800 for a split second but most of the time its around 4.6/4.7 even at 1-2% load.

Any ideas how I can get it lower? I'm sure my old 3770k @ 4.5@ downlocked to lower than 2GHz at idle?

Thanks.

I'm sure you need to offset the cpu voltage mate, takes a while cause you need to do it a step at a time to get it correct, but if my memory serves me right that's what ya need to do so that the voltage will drop and also the cpu speed when running on idle, read up on it and you will see if I am correct or maybe someone else will be able to confirm this or not ?

I have a 3700K and an ASUS board.;)
 
Ah, good point. I can't figure out how to do the offset voltage on this board. It's a bit of a weird bios to setup compared to other boards. Anything stick out in the screen shots?

just go through them cpu voltage options in the bios mate, one is bound to bring up offset options I think, its hard to say because its different mobo from mines, know what I mean ?

I would imagine that it has got the option to do that though, I might be wrong though, not sure about MSi boards, the last MSi board I had was a good board but a total nightmare when clocking, but yours looks as though it has a lot of options there, mines was one from yearsssssssssss ago.

AFAIK power saving features don't work when using the 1.25 strap, I don't think your system should be going down to 3800 though?
 
Well after days of having a good fiddle with it, youre absolutely right that normal power saving doesnt occur when using a strap. It is downclocking but nowhere near where it would be if it was just a straight multiplier clock.

Also, this MSI board doesnt have a CPU voltage offset! Its an X79A-GD45 (8D). Kinda odd but its mentioned on their forums.

Settled with a clock of 37x127=4.7GHz. Going to leave it at that and start playing some games now.
 
It shouldn't be downclocking to 3800 at all, are you sure it's not throttling? unless it's just a glitch with whatever program you're using to monitor the clockspeed.
 
Yes, its definately downclocking. Its under water so its not throttling. Would have liked to be able to automatically reduce the volts to save some watts but doesnt look like its possible with this board.

Speedstep will normally go down to 1.6ghz or so, with 1.25 if it worked it would probably be 16x125=2000mhz. I'm not sure why yours is dropping into the 3ghz range... if I was you I'd make sure you haven't hit some sort of power or VRM overheat limit where the motherboard is throttling the CPU down.
 
Its not throttling. If I run Prime then it stays at 4699 MHz all the time. I'm pretty sure the not downclocking all the way is down to this MSI motherboard. As soon as you set a manual voltage, it affects the power saving settings. Weird but its mentioned on the MSI forums.

Anywho, its doing what I want (to a degree) so I'm happish with it downclocking a little although if anyone knows how to get some power savings with a MSI X79A GD45 (8D) when idle, please let me know.
 
That's strange then, does your voltage go down at all? the cpu downclocking to 3ghz is not much of a power saving. How far does it go down if you run with 1.00 strap?
