Can't overclock my AMD X4 Phenom 940 with M57SLI-S4

post #1 of 6
Thread Starter 
The problem lies within the Cool N' Quiet I think. Any changes I make to any of the settings overclocking or underclocking will disable Cool N Quiet (as it should) and as a result my computer fails to boot into Windows. It POSTS just fine but I get a black screen with a small white rectangle in the upper left hand corner when any changes are made to my CPU (even simply disabling Cool N Quiet in the BIOS).

I am using the latest BIOS the FHm. I am aware that this is a newer processor on what is now considered a well aged board (though the CPU is a few years old now too) but it is still a heck of a good rig for everything I want to do, I am not trying to get a whole lot of OC done with this CPU, maybe from the stock 3.0 Ghz to a stable 3.5Ghz. Everywhere I look people seem to be able to get higher speeds with stock cooling and I have a Xigmatec aftermarket heatsink that I just installed on mine so 3.5 Ghz doesn't seem too hard. Also, this processor is the Black Edition so I know that it has unlocked multipliers and OCing with it should be fairly simple, so really my only problem is this Cool N Quiet nonsense.

After a bit more research, a Gigabyte forum moderator said:
"Sadly, on these older mobo's the BIOS chip is only 4MB and there is only so much information these chips can hold. With each addition of the BIOS, where support for new CPU's and other hardware has been added, it becomes inevitable that some features have to be removed. Quite often these are the features that are considered "extras" such as core unlocking (on newer boards) and overclocking which are normally used by very few users."

So basically this MOBO won't support overclocking this processor because the memory for overclocking this processor isn't in the memory of the chip.

Is there any way to change this, around this? BIOS modding?

As far as I can interpret that email response they say that when they introduced the support for newer CPUs they have removed optional features like overclocking.

There are two options really:
*use an older BIOS version that doesn't have support for example for AM3 Phenom II X6 processors; or just use the first BIOS that had support for the 940
*use a full-software method of OCing. While most Windows OCing utilities are junk the latest AMD CPUs have a soft called K10Stats that has all the OC options you need. My PhII 940 can reach 3.7GHz easily or an OC to 3.2GHz while undervolted from 1.35V to 1.25V, this vouches that the soft works. There could be some hiccups with mobo compatibility, but hopefully all will be ok.

*EDIT: I've just taken a peek at the Gigabyte site for your board. Apparently the motherboard has 3 different revisions and NONE supports the Phenom II 940. It does work for you, but the lack of OCing options may be explained that the motherboard doesn't "know" the CPU. In this case K10Stats may be your best bet. I also looked a bit at the motherboard specs, it can have problems with 125W+ CPUs - if you decide to OC take care of the MOSFET cooling (the area between the I/O shield and the CPU).

Yeah, I was looking at software overclocking. I tried EasyTuner but I couldn't adjust the multiplier and any Freq. adjustments just caused my system to lock up.

I will give this K10Stats a shot and let you know.

Thanks for the help dragosmp.

I have no clue what this is, lol. I will look into this because I did see that there was a bit of a potential problem with the 125W CPU

Am I right to think that with K10Stat I just need to adjust the FID (which seems to be the multiplier) for the P0 state?

EDIT: After setting the FID to 20 (to get 3.6 ghz) and clicking apply my system crashed. Maybe it was too high? This utility seems to control the different C&Q states which will be good as I can't disable C&Q ever.

EDIT2: http://www.gigabyte.com/support-down....aspx?pid=2539 This is the page for my board revision, it does list the processor I am running as being supported under the AM2+ category.

Here is a shot of my CPU-Z:

Well damn. I even got a BSOD when I was at 3.2ghz at 1.25Volts using K10Stat.

I guess no OC for this guy.

This board does NOT support the Phenom II x4 940. This is due to the Am2 base design and extremely limited 3 phase VRM setup. There is NO support for Phenom II 125W processors. You need to stop trying to overclock because you will likely fry this board when doing so; plus the older nVidia chipset not so suitable for Phenom II quad overclocking. It's not supported to begin with. Get a new board.
