Anyone had a chance to o/c the Northwood B's yet?

Hi. I was thinking of buying a P4 2.26GHZ Processor with the 533MHZ FSB. I wanted to know if anybody has had a chance to overclock these new Northwoods yet? Do they overclock as well as the earlier Northwoods like the 1.6A? What motherboard would you recommend? Also, what would work better for both performance and overclocking, PC1066 RDRAM or DDR400 RAM? I know many of you disagree on this, but I still can't decide which one to get. Thanks for the help.

PC1066 is better performing than DDR400 at stock speeds. It also cost less and should overclock further.

What's the frequency, Kenneth?

Agreed.

Here is my Northwood B <A HREF="http://fugger.netfirms.com/3122.jpg" target="_new">2.4Ghz @ over 3.1Ghz</A>

Abit TH7-II RAID and Samsung PC800-40

They overclock very nicely.

Is your RAM at full speed or 300?

<font color=blue>Hi mom!</font color=blue>

I have no experience with DDR400 or PC1066, but I would venture to say that since PC800 RDRAM was notoriously a bad overclock that PC1066 would likely be a bad overclock as well. RAMBUS doesn't have as good a track record as DDR when it comes to overclocking.

But again, I'm basing this assumption on the past performance of DDR and RDRAM, and I have no direct overclocking experience with DDR400 or PC1066 or the new PC800 that are certified to do PC1066.

Seriously fugger, that result is outstanding, you must use some pretty heavy cooling, VapoChill ?

Memory setting must be at 300 with that FSB and PC800 Samsung RDRAM, no doubt about that.

Please give some more details about the setup. I would never have expected what is essentially a factory overcloked 1.8A, running at 2.4B, would overclock that much further all the way up to FSB 173, no matter what kind of cooling is used.

I'm speechless.

Kilgore, Samsung PC800 hits PC1066 with no problem, I don't see how that's poor overclocking? I wouldn't expect PC1600 to hit PC2100 speeds at the same settings.

Copenhagen, FUGGER uses a refridgeration system from an old Cray. It cools the ambient temps down to a few degrees above freezing, I believe.

FB,

Like I said, I wasn't talking about the niche product of PC800 that can do PC1066. Read my post again.

Bum_Rush was asking how PC1066 and DDR400 was at overclocking. If you exclude niche products that came out in the last few months because of the lack of official standards, and instead look at DDR333 and PC800, then you can surmise that since PC800 was a bad overclock compared to DDR333 that DDR400 would likely be a better overclock than PC1066

Again, I am comparing past products of DDR333 with PC800 to draw conclusions on todays products of DDR400 and PC1066. This conclusion may be wrong. I don’t prefer DDR over RDRAM, so I’m not some zealot with a blind eye. I’m just giving my opinion based on experience in order to help someone out. So FB, cut me some slack, your all over me every single post I make.

Samsung RDRAM has been able to hit PC1066 for quite a while now, not just the last few months.

What RAM are you using for PC2700? Not every type can get much above a 166 bus.

I treat you the same as everyone else on this board, sorry if it seems otherwise.

Most pc1600, FROM ALL BRANDS, hits 2100 easily, its just like pc100 ram to 133, most pc1600 is downbinned, process refinements have made ram which bins @1600 very rare.

We now return you to your regularly scheduled debate.

May 28, 2002 10:29:09 PM

Yes, I agree. I meant PC1600 when it was new and the best RAM available. PC800 isn't downbinned (well, it might be starting, but it hasn't been this whole time). I don't think that most PC1600 was hitting PC2100 when it first came out.

My ram is at the 300Mhz divider.

I use <A HREF="http://www.lytron.com" target="_new">Carswell AC</A> + custom watercooling now. I recently adopted watercooling and taken it to the extreme.

Here is <A HREF="http://fugger.netfirms.com/woody.JPG" target="_new">my chiller</A> set at -17c

This is looking <A HREF="http://fugger.netfirms.com/installing.JPG" target="_new">inside the case</A>, there are no fans in my system now.

You can see my GF4 waterblock hanging, I was watching for condensation and checking temp with laser temp sensor. That block is silver plated copper.

My motherboard is holding me back at 170FSB, I have a few new prospects on the way.

My DRCG crap out at 155x4.

If you notice my voltages in the 3122Mhz pic, That is a tweaked Enermax 431 whisper quiet. That is how you want your "rails" to read under full load.

You are limited to what your mind can perceive.
May 28, 2002 11:12:21 PM

I can hit PC1400 speeds now with 400Mhz DRCG's.

It is not the ram holding me back, I hate to swap out motherboards as this one is perfect in every detail and it only tops out at 170FSB

If I may turn your attention to <A HREF="http://www.vr-zone.com" target="_new">here.</A> The new high score P4 was updated recently. those P4 2.4A's over 4Ghz on a 533 mobo.

That's impressive, but I hate screenshots of LN2 cooled that are barely stable enough to boot.

nice cooling. but no MCH cooling beside the passive HS?

That's damn impressive. Is it stable under full load?

May 29, 2002 4:52:57 AM

That is everything this motherboard could give it, maxed out at 170FSB with the 1.6a x2 and the 2.4B

I can hit 170FSB with 1.8 vcore, in that SS I was up to 2.02 vcore trying to push harder. The motherboard is holding me back.

Point me to where I can get PC1066 cheaper than DDR400 and I'll be a happy camper.

Gosh I'm such a nerd sometimes, but then again arn't we all. :smile:
May 29, 2002 8:20:07 PM

They probably will be equally priced, or maybe DDR400, a tad less. I am looking forward for DDRII with Dual Channel, that would one day rock!

Well gee, DDR really did drop in price the past couple weeks didn't it. I should check more often!

Then again, the price difference is around 50%, which sound's like a lot, until you look at it like this-it will raise your overall system performance at least 5%, whill adding about 5% to the total system price. An even payoff for toping off a highend system is still a good deal!

What's the frequency, Kenneth?
May 30, 2002 6:53:52 PM

FUGGER, I have some questions:

1. Do you have any idea of how high your 2.4B sample can OC with stock cooling ?

2. I know that you work with computers for a living, so I guess that you maybe have access to a number of different P4's. Is your current 2.4B "cherry-picked" among number of P4's, and if so, how is your impression of the OC'ability of the different versions ? (1.6A, 1.8A, 2.0A, 2.2A, 2.26B, 2.4A, 2.4B).

<i>/Copenhagen - Clockspeed will make the difference... in the end</i> :cool:
May 30, 2002 9:11:41 PM

I have setup a few 2.4B's with stock cooling and the average 2.8 ~ 2.9Ghz without mods @ 1.7 vcore.

My 2.4B is not hand picked, it was one of the first batches released from newegg.com

I have new motherboards arriving today and tomorrow.

The northwood B run at a lower vcore than the A at higher speeds = lower temps.

Northwood A = sub 3Ghz
Northwood B = 3+ Ghz
with good cooling on average so far

1.6A best bang for the buck on budget
2.26B is the new "300A"

Samsung updated RAMBUS roadmap, very nice stuff planned for RDR platform.
