Do the other Northwoods O/C as well as the 1.6A ?

[Guest]

I've been reading a lot of posts from people that say they have gotten their PIV 1.6A Processors to run stable at 2.4GHZ. Does anybody know if the other Northwood processors can be overclocked just as well, such as the 1.8A, 2.0A, and 2.2A? If so, that means a 2.2A should be able to get close to 3.0 GHZ, right? Thanks for the help.

No, they don't. The higher clocked the Northwood the less percentage you'll get extra out of it from overclocking. I doubt a 2.2GHz will go over 2.6 or 2.7GHz on stock cooling.

Yes, they clock as well and some better.

The current 2.4B is reaching 3.2Ghz on air cooling.

I have seen many 1.8a that breach 3ghz

1.6A is the most bang for the buck for overclocking and budget systems.

first page is mostly LN2 and dry ice cooling. but you will get a good idea what each P4 level is capable of.

Don't get me wrong, the P4 is an excellent overclocker, but overclocks this high are possible with convential air cooling. That site shows the maximum overclocks not the average.

Here's a more accurate database of overclockign speeds. <A HREF="http://overclockers.cssftware.com/cpudb/index.cfm" target="_new">Link</A>

The 2.2GHz P4 reachs over 2.8GHz so a faster P4 may just reach 3GHz or so, but it's not very likely.

I have found the higher grade of CPU does clock higher on average.

Its all a crap shoot on how high any given CPU will overclock. So Cooling is the final factor.

You will not overclock worth a damn without good cooling.

[FUGGER]

Even the link you posted shows increases on each grade of CPU.

1.6a= 2856
1.8a= 3113
2.0a= 3200
2.2a= 3675

But this does not mean you will reach these speeds.

All are good overclocking if your are going on 1.6A you need a very good mobo because you must go a very high FSB around 133 to 166.So forget RDRAM or you can find some Pc1066.

[AMD_Man]

Why are you looking at the maximum? The average number is more reasonable for stock cooling.

Forget RDRAM? YOu could always drop to the PC600 mutliplier and run PC800 at "996" with the bus speed at 166, giving you roughly DDR400 performance.

What's the frequency, Kenneth?

true i have forget the 3X multiplier.

But still wait for a mobo with 600 clock generator.

Max overclock shows the consistant increase in speed grades, not flat lining at 2.8Ghz

I use "quotation marks" to indicate when something is a speed by name only and not a true frequency.

No, they don't. The higher clocked the Northwood the less percentage you'll get extra out of it from overclocking. I doubt a 2.2GHz will go over 2.6 or 2.7GHz on stock cooling.

well lets see, you've got uncertainty part, the doubt part and now all you need is some fear.

way ta' go AMD_man!

He posted a link. Fugger posted a link. They seem to be having a healthy debate. Anything you'd like to add to it?

AMDMeltdown, what are you implying? I agree with Fugger!

I disagree with you on that. A single CPU that gets extroardinarily high could skew the results. Average overclock is a much better comparison. Granted, you have the idiots skewing the results down, but I still think it's more accurate than taking the max.

No matter how crude the data is, each speed grade reaches A higher speed on average.

True, there are some exceptional overclocking chips and people use LN2 but the data at overclockers.com supports my statement.

Now look at vr-zone.com's P4 database, it shows the P4 1.6a above several other speed grades. These are somewhat unrealistic overclocks for the casual overclocker to reach.

Final factor is the luck of the draw.
