My initial FSB overclock and a few queries
My initial FSB overclock and a few queries
Hey there, I just tried overclocking my CPU for the first time. Here are the settings I used:
FSB: 400 MHz
CPU ratio: 9.5
C1E support: off
Max CPU CPU value limit: off
PCI frequency: 100
DDR frequency: 801 MHz
CPU voltage: 1.30625
CPU margin: performance mode
The system runs smoothly with temperatures staying between 45-60°C during Prime95. The only issue I noticed is that in GTA V, the map runner lags when using this configuration—something I hadn’t experienced before I overclocked.
My questions are:
1. All voltage settings except CPU voltage appear to be set automatically. Does this pose a risk of damaging the hardware or reducing performance? I’ve heard that auto-settings can cause overvoltage and harm when overclocking. Is manually adjusting most voltages actually beneficial?
2. The guide suggests setting RAM ratio to 1:1 for DDR2. I couldn’t find that exact setting, but I did see an option to manually adjust RAM frequency. Does this function similarly by changing the speed?
3. Are there any other settings I should enable or adjust to boost performance further?
Specs:
Asus P5Q Se PLUS
Xeon X5460
4 x 2 GB 800 MHz DDR2 (unbranded RAM)
Nvidia 750 Ti FTW edition
Any advice would be really appreciated!
I don't like this kind of overclocking because it stresses many components without the ability to adjust them separately. Keep a close watch on your Northbridge temperatures—they'll be a bit higher than your CPU core temps in this situation.
-A 1:1 ratio means that if you configure your FSB at 800mhz, your RAM should also be set to 800mhz.
-Don't rely on auto voltages during overclocking. I wouldn't use them at all personally (motherboards usually provide more than necessary).
-Lower voltage leads to lower temperatures.
Determine the necessary manual voltage adjustments beyond core and coupling voltages. You can refer to standard guidelines or documentation for a general reference on configuration.
The sole additional factor to confirm is your RAM voltage. Many motherboards operate at such levels even during standard performance settings.
