    Dunno about more OC, but IIRC, ASUS Mobos let you disable onboard graphics.

      Reaching more than 2Ghz stable in a 5150 is more than possible as show in this review http://goo.gl/UPtPaF with same motherboard, CPU ratio Auto and 2133 memory.

        Change the SATA controller to IDE mode, the FM sockets have always had a "bug" that prevented overclocking beyond ~105 MHz bclk with the SATA controller in AHCI mode.

        AMD has probably reused the controller setup from the FM sockets on AM1 resulting in the same "bug".

          ...and how about bump up the NB frequency ?

          I just did it in a A6-5400K that was running RAM at 2133MHz but NB was still at 1600MHz and was bumped to 2000MHz, a lot of perofrmance increase.

            Somehow i ALWAYS use IDE mode in SATA...guess this is one more reason to continue to do so

            BTW, i know that some MoBos had problems in the past with more than 105-107MHz base clock and Sub-D VGA....do you know if that setting SATa to IDE indirectly solves also that problem, or , if using VGA connector continues to limit to 105-107MHz base clock ?

              Unfortunately I do not own an AM1 setup, but a guy on OCN managed to OC his, and I'm sure the images earlier in this thread is from the very same guy.

              You can read about it here: http://www.overclock.net/t/1483429/amd-kabini-owners

                How to overclock over 105 MHz on AM1 platform.

                Why did all CPUs get at a maximum of 105 MHz? Coincidence? No!

                There is a solution!

                The 105 Mhz limit is caused by the sata controllers on the motherboard. In fact, it is the AHCI mod that limits the the speed. This has also been an issue on AMD FM2/FM2+ boards.

                The only thing you need to do is to change the SATA mod from AHCI to IDE.

                I got the exact same issue, as my Athlon 5350's fbs was capping at 105. I tried to change my hard drive, reinstall windows, but nothing worked.

                Then, I changed my SATA mod to IDE, and also had to reinstall windows because IDE drivers were not installed and I could not boot.

                Now, here is my specs:

                Core speed: 2667.30 Mhz \\\ FSB speed : 127.00 Mhz \\\ Core voltage: 1.464v \\\ Core multiplier: x21.0 \\\ Max temps on prime95: 65C

                I hope you guys find this useful.

                  Overclocking The AMD AM1 Athlon Sempron APUs

                  the link does not work, also is there any way to pin mod it or something?

                    No pin mod

                    I am very far away from being an engineer, but I'm pretty sure there is no way to pin mod an AM1 APU because it happens to be a SOC.
                    Therefore, the northbridge is located on the APU itself as is the PLL. The PLL, or phase locked loop, is the chip responsible for producing the FSB frequency (often 100.00MHz) that drives all components of the motherboard.

                    So, because the cpu doesn't need to use the socket to communicate to the PLL, I'd say it is impossible to change the FSB using pin mod.

                      That does work for Windows, but not work for Linux Of course you can overclock it for Linux but if you not using SATA drives, USB2 or USB3 drives should work.

                        But yeah, it is also fine if you want to have situation like "oh my... this Linux shit does not even work!!! "
