How does the Newest Version of the P4 2.66GHz overclock?

Overclocker456 · Nov 17, 2002

Back in September I bought a P4 2.66GHz CPU and my 2.26GHz chip overclocked high than it.. My 2.66GHz couldn't even do 2900MHz... I'm curious to see how the newer pack dates are doing.. I haven't seen any new threads on them in a while..

Nobody probably cares about them anymore? .. the recent 1.8's are the best bang for the buck now!

You must be taking about the new C1 stepping 1.8A.. and they're not out yet.. only the OEM's are... we can't buy them...

I'm eyeing a 2.66 myself. Looks like a good starting point for solid medium-fsb (133-155Mhz) overclocks at good core speed.

No I'm not, this is my B0 1.8 that I got yesterday!

with 3:4 mem ratio too! waiting for C1's is good, but can you wait?

My 2.66 gets me 3.0Ghz with only 1.57v actual, idling around 41C. I had it up to 3.2Ghz using 1.72v actual (higher than I like).

2.66 @ 3.0GHZ on 1.575Vcore with RAM at 3:4. Idling at 29C right now (about 77F in here). Gets to 47/48C under Prime95 load.

That is definatly a amazing overlock.. What voltage are you using ???

Would there be any difference between a 2.6 and a 1.8 @ 2.6?

1.6v .. the interesting thing is, it's on default vcore @ 166fsb (3ghz) and a whole .1v for another 4fsb lol .. I'm trying to make her stable @ 3.2 as we speak.. needs more burn in I assume.

- 2.6 @ 2.6 = 100fsb
- 1.8 @ 2.6 = 145fsb

So yes, better memory bandwidth

.. *ANY* 1.8 with SL68Q packing date late Sept+ will do 150fsb with an ease.. That's a given 2.7ghz just like that..

Thanks pacino, very helpful.
