This is my setup :

Biostar TP35D2-A7
Intel E2140 1.6ghz (With stock cooling)
2 x 1gb Kingston PC6400 valueram
XFX 8600GT Fatal1ty (Factory overclocked)
Samsung 320gb HDD
Sony DVDRW
CoolMaster Extreme Plus 460w (Dual rail)

The max i can clock is 8 x 320mhz. And only at 8 x 305 that the system is stable without getting freeze on games. The only thing i changed on the bios is the frequency from 200mhz to 320mhz.

A google search tells me that i can bring it up to 2.8ghz(at least, with stock cooling). Can someone please guide me on what other changes should i make in the bios? Here's how it looks like :

"The only thing i changed on the bios is the frequency from 200mhz to 320mhz"

What about memory settings? PCI-e frequency? voltages? You *should* be able to get the CPU freq up to 400MHz & run the RAM in sync. 2.8GHz (7 x 400) or even 3.2GHz (8 x 400) is possible, if you know how to set things up. You have to set the Overclock Navigator to "manual overclock" then tweak the settings from there.

i have no idea what is the figure i should set for the memory, it's on auto now and i leave PCI-e frequency to its default value. how should i set both the setting? i've try upping the cpu voltage to 1.45v but it makes no difference, i still can't get it run at a higher frequency. so i revert back to its default value.

I read about the "CPU EIST" setting which when disabled, i can lower the multiplier and up the fsb? but before i try it, anyone know if there's any undesirable effect if i disable it? also, is the E2140's clock multiplier locked?

thanks

The memory is most likely overclocking along with the CPU so if you have the memory set to AUTO, that what's holding you back. Try it at 533MHz & make sure the PCI-e is at "Fixed 100". Temporarily lower the CPU Clock Ratio to 6x & set the CPU Clock to 333MHz. Leave all voltages at defaults. Save your settings, reboot & re-enter the BIOS. The CPU should now be running at 2.0GHz but more importantly, see what the memory frequency is listed at...with any luck, it *should* be 333MHz. If it is, raise the CPU Clock to 400MHz (leave all other settings as they are), save your settings & reboot. The CPU should now be running at 2.4GHz with the memory frequency at 400MHz. If that is correct, all you need to do now is raise the CPU Clock Ratio from 6x to 7x (for 2.8GHz) or 8x for (3.2GHz), however, this is the point where the CPU voltage may have to be increased. It's trial & error.

EIST = Enhanced Intel SpeedStep Technology. I don't know if your BIOS even has that setting as an option but if it does, it should be disabled.

Thanks jam. will try it out and back with outcome.

Nope. lowering the clock multiplier and raising clock speed did not work. Even at 6 x 333mhz, the system failed to boot, the screen was blank and i need to reset bios jumper back to default :-(

You apparently didn't change the RAM freq setting. When you raised the CPU freq to 333MHz, the RAM overclocked way too much & that's why your system wouldn't boot. You have to lower the RAM freq to 266MHz (DDR533).

EDIT: sorry, I just realized that the E2140 is an 800MHz FSB CPU. Set the RAM freq to 200MHz (DDR400)...that *should* give you the 1:1 ratio.
