Need help translating Foxconn A79 A-S bios

[Markfw]

OK, so I just got another 940 BE, I was going to set this one up just like the other one. I went into the bios, and its like WTF ? Where is the multiplier ?

Any help is apprectiated.

What I want is 19x multi, up the vcore to 1.4, HTT=4, simple things, but I can;t find it anywhere !

Well, I think I figured out part of my problem. Even after a bios flash to the latest, it won't go over x13 multi, unless I say "auto". So I upped to fsb to 230, and its now 3450.

Great motherboard. Horrible bios...

agreed, as you can see by sig, I kept the MSI K9A2 as my primary board, with the 1.7 bios im finally aloud to use RAID + 1066 ram so it became the am2+ board i always wanted again without ACC features which are pretty useless on my 940BE

Wow, that is strange!

You have to change FID and DID under "AM2+ ratio adjust", leave DID on 0 and change FID to:
http://ocia.net/aimages/309_5_full.jpg
* DID = 1 would divide the resulting FID by 2
* I don't know if the bios accepts hexadecimal numbers, if not, then 0a in this graph would be equal to 10 in the bios and a 13x multiplier, 0b = 12 = 13.5x, etc.
* Some say the P07 bios has issues with cpu muliplier control, try P06 if P07 doesn't work

There's no direct voltage control, only a + box (first item under voltage settings).
If you type 1 in there you get 0.024 extra volts, 5 will net you 0.12 extra. These extra volts will get applied in any powerstate if you're using CnQ. 940 standard has 1.35v but this board overvolts to 1.375 by default. So to get 1.4 you need to just put 1 in the box.

Another (and imo better) option is to only set htt and northbridge clocks in bios, and let K10stat do the multiplier and voltage manipulation after boot. This way you can keep the P07 bios because P06 has other issues. Also keep in mind that K10stat doesn't take into account all voltage bios settings. 1.35v in the program corresponds to 1.375 real volts on the foxconn. If you put 1 in the + box in the bios, then 1.35v would correspond to 1.4 real volts on the board. If you put 1.3v in the program then you would get the actual 1.35v with aforementioned settings. Use cpu-z to keep an eye on it.

Remember that the northbridge multiplier (you can only change that one in the bios, no windows program) has the same system as the cpu multiplier but with a different scale!!
FID 6 equals 10x multi there, and every step up is a full multiplier step up (7 = 11x etc.). The 940 has a default NB-FID of 5.
Foxconn doesn't offer a DID part for the northbridge, it's fixed at 0. Foxconn also doesn't offer a CPU-NB voltage control but luckily K10stat provides that.

And leave ACC off on phenom 2

Another tip: try a cold boot when changing any of above mentioned settings. I learned the hard way that my PII920 (non-BE) its CPU-NB multiplier could only be changed on reboot, but any setting other than default would hard-lock before posting on cold-boot, necessitating a cmos clear every time. I'm assuming it's because the PII920 doesn't allow NB multi manipulation, but it could be the board as well.. (I should have gotten the PII940 )

Wow, an expert ! Exactly what I needed. But slow down a little. If I want to set the htt and nothbridge clocks for 3.7-40 end speed, what do I set them to ? and where is this k10stat program ? (I will try and google it)

Edit: I got the software, when I tried it the first time to set to multi 16, it rebooted. Then I played with the FID and DID and HTT, etc for over an hour, and no luck getting past 3375.

So now I am back to 235x stock (with some vcore bumps) and it seems OK. 240 for 3.6 was OK, but re-booted after 5 minutes. 235 was working all night.

i have the p45a-s and there's no doubt foxconn has the weirdest bios i've seen in a long time... i just wonder what their reasoning was for making it that way... cheaper programming? fits in smaller chip? there had to be some rationale for doing it that way...

sorry, lost track of thread
I would just put everything on default in the bios, load windows, run stability tests (occt memory and occt cpu or prime blend and prime small fft, each at least 30 mins) to make sure everything runs ultrastable.
Then change only the FID in K10stat (second tab, select P0, dropdownbox FID to new value, click apply, click ok -> run a shortcut with the commands "X:\...\K10STAT.exe" -loadprofile:1 -nowindow )
Run cpu stability test again (occt cpu or prime small fft) - check cpu-z while testing to see if k10stat applied everything OK. Increase volt in k10stat if test fails. Rince and repeat till you found your max/desired cpu clock.
If you do it the HTT way, other aspects of the system could be limiting your overclock - in my case, the memory caused a lot of errors.
