Hit the FSB/volt wall on my E2140?

[°TheMadDutchDude°]

Hey guys, as you know I have an E2140 and I love to push as far as I can though I can't seem to get it to boot up at anything past 440FSB or 1.5875v.

When I try to boot up at 1.6v it just refuses to POST, if I try to boot up at 441FSB.. it refuses to POST!

Do you have any ideas what might be the problem? I have tried upping my VTT to 1.45v.. doesn't help. I am running an MSI P35 Neo2-FR motherboard if that gives you any ideas.

I have the suspicion that I have problems because I have a 4pin 12v connector.. not having the ability to shove power in to the CPU when it is needed, does this sound like a familiar problem to you?

Thank you guys!

Voltage Settings

You need to lower that VTT voltage, this would not help the OC at this stage, since 440Mhz is not that high. You should Increase the SB I/O Power to at least 1.6V (i'd recommend 1.7 (not 1.8), but 1.6 will do more than enough). I have an MSI P35 Platinum & I am able to reach a FSB on my Q6600 of 1700Mhz (425 * 4) with SB I/O Power @ 1.5. If I want to run it @ 450, i'll have to increase only the SB I/O Power to 1.6V. Try it, you'll then even reach higher clocks. Oh, yes, remember to (not in all cases) increase CPU voltage, to whatever you want to OC & also remember to step down the multiplier of your CPU, in some cases. Like for me, to reach FSB 1800Mhz, i had to decrease the multiplier to 8x (3600Mhz). Remember, if you increase the FSB only (but the stepping down the multiplier), no voltage adjustments for the CPU is needed, only for the Chipset, like the SB I/O Power. But, if you are Increasing the FSB & leaving the multiplier on 8x / 9x, then both CPU & SB I/O Power adjustments are needed. Go try this.

Thanks, but I know it is the CPU limiting me, I've had my NB and SB at 1.45 and 1.8v and it did nothing for me.

Also, I've tried it in another motherboard with higher volts through both and it wouldn't clock past 440 either.

Most E21x0's have a lower FSB wall. You're currently walled by the chip and you're actually having a good chip.

The best I've seen on a E21x0 is 450FSB. Most tend to get nasty around 400-415, some can't even hit 400.

You can up your voltages all you want but breaking through a wall probably won't happen.
