How can I overclock my system?

[ky0t0]

Hello, i have never made overclock before, i would want to try it now with my new rig :)

My system is:
Gigabyte GA-EP45-UD3P (bios F5)
Corsair Dominator PC8500 (2x2Gb)
Intel Core2Duo E8500
Powercolor HD4870 1Gb PCS+
Thermalright 120 Ultra Extreme
Corsair TX-750W
Samsung 750Gb 32Mb 7.200rpm
Coolermaster CM690

How can i setup my bios to get a decent overclock with my system??? (i would like to get about 4Ghz for a 24/7 use of the pc)

Thanks in advance :)

Re: How can I overclock my system?

U can use the same settings as i do, only lower your memory multiplier to 2.0 in stead of 2.4.
And your processor being of better quality than mine you should be able to reach it with lower voltage.

Re: How can I overclock my system?

thanks for the reply.

my only concern is that our motherboards are not the same...

Re: How can I overclock my system?

If your motherboard doesn't like 500 fsb, try a lower fsb with a higer multiplier, like 470 x 8.5 or 444 x 9 or even 421 x 9.5
The highest fsb should give you the fastest system tho, at even processor speeds

Re: How can I overclock my system?

ok, i'll try that, but can you put a list of the bios settings like i see in all other posts... that is really helpfull :P

i'm more than a newbie in overclock, i can call my self a noob :( that is why i am so worryed about OCing my rig... i think you understand that

Let us know how your testing goes

Re: How can I overclock my system?

hi there, sorry i couldn't try to overclock my computer before, but i did not have the time to try it but today i was looking at my bios settings, and i can't find the Driving Strength Profiles, where is that?? i was trying the settings you have given me lsdmeasap.

Thanks in advance

Re: How can I overclock my system?

is side ... advancetiming controll under the ram ... then you see chanell A ,B ... the 4 line at bottom .... then go into chanel A driving setting .... top one is where you can set it ..... also do that for B

[Lsdmeasap]

Re: How can I overclock my system?

Right as said above, you will find it here >>>



Set so both are the same
