Overclocking the i5-460M CPU on the ASUS U36JC
NOTE: I take no responsibility for any damage(s) on your laptop due to this article. This guide is simply for reference only.
The process of overclocking the i5-460M on the ASUS u36JC is fairly simple. All you need is SetFSB (ver. 2.3.165.130 or greater, non-shareware). To acquire the non-shareware version, you now need to purchase the activation key (¥800 ≈ $9.60 USD). Once you've acquired the full version of SetFSB, you will then be able to use the overclocking feature.
1. Open SetFSB and select "ASUS G73JH" and click on the "Get FSB" button (the U36JC uses the same clock generator as the G73JH).
2. On the first slider, the default setting should be set at 140/760. Move the slider to 170/760 and click on Set FSB. This should overclock your CPU from 2.8GHz to 3.21GHz.
You can overclock the CPU up to 3.42GHz before your ram starts limiting your FSB and cause errors. However, I wouldn't suggest anyone overclocking beyond 3.21GHz since the heat sink in the U36JC isn't even capable of handling default clock speeds at load for long periods of time. 99 degrees Celsius is the temperature where your CPU starts throttling back and this temperature is easily reach during load at the stock 2.8GHz. Overclocks from 3.20GHz to 3.42GHz will all hit 99C during load and throttle back a few hundred MHzs until your CPU is cooled back down to a temperature in the mid 80s Celsius - then CPU will kick back to full power and the process repeats itself to prevent overheating. Note that the CPU stress tests that I perform is with Prime95. This stress test takes the CPU to its limits. Most non-benchmarking software will rarely utilize the CPU as extreme as Prime95 so for the majority of U36JC owners, it shouldn't be an issue. If heat is one of your major concerns, you can also easily perform the opposite and underclock your CPU if desired. Below is a list of various FSB settings and their corresponding CPU speed:
FSB (MHz) ....CPU (GHz)
170...............3.21
175...............3.28
180...............3.35
181...............3.36
182...............3.38
183...............3.39
184...............3.40
185...............3.42
186......Ram limitation/crash
Automating SetFSB and Overclock at Startup
These steps are almost identical to the ones I posted for the UL30VT/UL80VT/UL50VT overclocking thread. Please follow the steps carefully unless you are familiar with the SetFSB program.
1. Create a folder in any location and label it "SetFSB". I'd recommend putting this folder in a location where it won't be seen, such as your program files folder. Unzip the SetFSB file you downloaded and place its contents into the new folder you have just created.
2. Create a shortcut for the SetFSB .exe file and place your it in your startup folder (C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup)
3. Right click on the SetFSB shortcut and select properties. Under the Shortcut tab, add " -w04 -s154 -cg[ASUS G73JH]" (without quotes) to the end of the Target. Your Target should look like this: "C:\Program Files (x86)\SetFSB\setfsb.exe" -w04 -s154 -cg[ASUS G73JH]
What this added string does is it finds your clock generator, overclocks your Bus speed & FSB frequencies so your CPU is set to 3.22GHz, and closes the program after it's done.
Similarily, you can also create a FSB shortcut to reset your CPU frequency by adding -w04 -s133 -cg[ASUS G73JH] to the end of the Target in a new SetFSB .exe shortcut. Note that once you restart your laptop, your SetFSB settings will also be reseted back to your stock CPU speed.
Last note:
-w04 signifies a 4 second delay before any setting is changed. You can change this to w-01 if you want to decrease the delay time to 1 second.
-s154 is the FSB frequency which sets the slider to 171
-s133 is the FSB frequency which sets the slider to 139
-cg is the clock generator setting
