Foxconn Black Ops X48 OC Guide
I have had the board for a while and thought I would share some of the basic settings on OCing this board. This was using the G17 bios and I am not sure if it will be the retail bios but it should be pretty close. First picture is of the standard bios page.
I recommend you go into Advanced Chipset Features and disable the System Bios Cacheable.
Under Integrated Peripherals I disable anything that I will not be using. In this case it’s the floppy drive controller, serial port, and IrDA device.
I also go into the onboard device control under Integrated Peripherals and disable the HD audio, 1394, and both Ethernet ports.
Here is the basic system monitor screen where you can set fan speeds and monitor temperatures and voltages.
Here is the bottom half of the screen. Note the voltages are reported wrong because this is an ES board running retail bios.
Next we go into the Quantum bios this is where the overclocking starts.
In the CPU Features the frequency unlimit is for the Extreme CPUs with unlocked multipliers. The cold bug boot fix should be left disabled unless you are sub zero. If you enable this on air or water and for some reason your CPU over heats the board will not shut down.
Phase change/dry ice/LN2:
In order to change the memory timings we need to change the Overclock Phase Select to Manual O.C. Then we can go into the memory timings.
These are just some basic ram settings you can try
The following are the timings I am running on my ram at 1800MHz 2.2v and a few have run up to almost 2000MHz with similar settings.
Here is the Voltage control. You see the CPU voltage goes up to 1.6v but there is also the voltage multiplier.
This allows for up to 2.4V!!!!!! to your CPU. Voltages were tested in the labs rock stable at 2.2v for the vcore. However that kind of voltage will kill your CPU. Make sure you use the vdroop option as well to remove the vdroop.
Here are the rest of the voltages I use for a 24/7 system. If you are going to be running that voltage on the NB, I highly recommend you use the supplied fan or water cooling.
Here we have the FSB, Multiplier, and Memory speed options. I found with a quad core around 450FSB is the max. The dual cores go a lot higher unfortunately I haven’t had a chance to test.
For me the 1:4 333 Strap ram divider worked best. Also make sure you enable Overclock recovery incase the Overclock fails.
The board allows you to store your overclocking settings with OC gear. It also shows what bios you are storing it to because this board has dual bioses in case one gets messed up.
Since clockgen hasn’t been updated you can use SetFSB with this board. Here is the following PLL to use. ICS9LPRS509HGLF
Feel free to ask any questions.
Special thanks go to Peter and the Quantum Force Scholars as well as Gautam for the ram settings. I will also be posting a guide on insulation and prepping the board for sub zero action.
