Will a 3.4 Prescott reach 4GHz+ ?

[Toff]

I ordered a 3.4 478 Extreme but sadly the box turned up empty! (my first e8ay problem in over 110 transactions )

As it seems almost impossible to get a plain 3.4 northwood (let alone an Extreme) - I'm wondering about a Prescott.

As previously mentioned, I'd love to reach 4GHz - will a 3.4GHz Prescott over-heat before it gets there?

My water rig is working well - my 3.0 northwood is running 3.7GHz (1.6v) and the temp is 34 idle, 37.5 under load.

Well that pee's on my bonfire

But of course you are right.. even without the latency issues, it'd be at least £150+ for a theoretical 300MHz raise! I guess I just got fixated on reaching 4 GHz!

I've got my Northwood 3.0 to around 3.7 by raising the voltage to 1.625v that means the FSB is around 255 (any further and it's unstable).

have I pretty much reached the limits of my processor, or are other people eeking more out of their 3.0 Northwoods?

Bundles.. that's amazing.. but I thought using a 5:4 ratio on the RAM wasn't as good as having a 1:1 (using suitably quick memory as AWPC suggested).

I thought raising the FSB (and core voltage - max 1.65v) gradually until the system proves unstable (then back-tracking until stable) was the best way to OC

Excuse my ignorance, should I drop the FSB back to standard and raise the multiplier instead?

Excuse my ignorance (again) but what does PI stand for please?

I settled for a 3.2 extreme edition. Without any OC'ing it beats my 3.0 OC'd northwood (3.7GHz) in the benchmark tests

So that's cool, probably due to the extra cache (and lack of errors going on?)

The extreme edition doesn't seem very happy to overclock though.. it'll only reaches 238 FSB and then it's unstable thereafter. Raising the voltage slightly doesnt seem to help at all.

Are extreme editions generally less friendly to overclock?

It has 2Mb catch dude, thats why it'll be tons faster

It should clock by a milestone being a Galantic core

What volts you pushing?

You set your ram to the slackest and hihest vdim and then clocked?

Oh and what bord too

Hi,

At the standard voltage (1.55v) it will run stably until 238FSB. I've tried pushing the voltage upto 1.625v but it's still unstable past anything over 238FSB (too chicken to raise the voltage any further! - the water cooling is working well, but I don't want to nuke the CPU with too much voltage!)

The ram is OCZ 4000, so it's actually running below-spec (500MHz native). Should I still slacken off the timings?

I'm loving overclocking - good job you guys are here to help

Sorry, ABIT IC7-MAX3

Ah this be why, it's the bord you using not the chip. Get hold of Drazic asap and he'll get the bord modded up for you as it needs so many doing...if you don't belive go look at Hypro's site via google mate.

Thanks Lee.. I've heared about these mods before. I can't get in touch with Drazic because he's been susspended from the board

Is there anybody else who can do the mods?
