FSB

[kg988]

Hey,

What would be a safe overclock for my computer? I just need a little boost to stop mild jumpiness when gaming (crysis with max settings and resolution). I dont really want to jepordize stability or reliability. I have heard a great way to get a jump in performance is to overclock the FSB.

Here are my specs:

AMD Phenom II X4 955
Sapphire 4890 1gb (already overlocked GPU of 790 mhz and memory at 900mhz)
G skill ddr3 4gb
MOBO is a gigabyte GA-MA790GPT-UD3H


So what would be the best FSB speed to give my system a boost? Easytune 6 claims my current speed is 200 mhz...but i have also heard to change it through the BIOS, not easytune. Also, the specs of my mobo say the FSB is 2600 mhz, so i dont know why it says 200mhz....

Anyways, any information would be helpful. T

Thank you.

the reference clock of your system is 200mhz. the hypertransport (HT) frequency is 2600mhz. If you're going to change anything for sure do it in the bios. just bump the multiplier up one to 17 and you will have 3.4ghz. that should be stable on stock voltage. you should be able to raise the multiplier to 18 for 3.6 ghz on stock voltage with good cooling.
