There is a new Bios out for our board - F4a - however after flashing, my memory reported in Windows was DDR3-1333, even though the bios was set to 1600, and even when the system starts, it says MEMORY 1600Mhz.
CPU Speed & Voltages seemed to be all over the place... constantly changing, and never settling in.
I didn't experiment much, as I ended up going back to the F3 bios.
To the gent above me.....
I'm stable @ 4.3Ghz with Normal vCore, and an offset of -0.010.
That gives 1.320v (yes, it's high, but with no Load Line Calibration option, it's got to be high to compensate for vDroop!).
On Prime95 with all 4 cores 100%, vCore will drop to 1.284v, and that's plenty stable for 4.3Ghz.
Because of the -0.010 the 1.6Ghz vCore is .984v (very low), and CPU will idle @ about 24-26c.
Cores are between 30 and 37c respectively.
For 4.4, you can set your Offset to 0.005, or no adjustment at all.
Bios will be 1.330, and vDroop is 1.296 under 100% load.
This is not necessarily good... let me explain why......
@ 25% CPU usage, you are going to see readings of 4.4Ghz, and 1.33v, that's quite high for only 4.4Ghz.
@ 50% CPU usage, 4.4Ghz, and a slight vdroop to 1.32v
@ 75% CPU usage, 4.4Ghz, and another vdroop to 1.31v
Most CPU's never reach 100% on all 4 cores, unless we use stability programs... or folding. I didnt say all, I said most!!!
So for all intensive purposes, while 1.33v is stable, it's much to high for everyday use......
In a perfect world.
What we want is.
vCore @ 1.296v and for it to stay @ 1.296 for 4.4Ghz @ 100% load.
When idle it SHOULD drop to 1.0v, and 1.6Ghz....
I cannot find any combination of that happening on this board (and maybe it's simply NOT possible... period!)
What I don't understand is... why can't Load Line Calibration be used when the Vcore is set to NORMAL.
I'm convinced as well, that setting vCore to Auto, LLC has no effect.
Setting to LLC2 thru 10 results in the same outcome - usually a crash, because Auto doesn't set the right voltage for 100% CPU Load - vdroop kills it!
It may be FIXED in the F4a bios, but I never stayed on there long enough to test... Voltages were all over the place, and memory speed was incorrect.
