View Full Version : Is Northwood All Bark and No Bite???

I'm just wondering, because I've heard so much about how the new 0.13 micron core "ought" to overclock unbelievably...blah, blah.... Unfortunately, I haven't seen any good overclocks with it. I've only seen about 10%-15% overclocks. Not very impressive in my opinion.
I'm just wondering, because I'll be building my next system in about 2 months, and had planned on a Northwood, but now I'm not so sure. Does anyone know of some successful overclocks to the 2.4-2.6 GHz range? (without LiN or other extreme cooling?)
I'm sure it is still a locked multiplier/bus issue with the Intel chips, the core will go very high but the components are crapping out... unlocked versions are hitting the 3.0GHZ range from what I've read.

What about either of:
1) "Settling" for a 133FSB which brings the 1.6 to 2128 and the 1.8 to 2394 and keeps your PCI/AGP in spec with a 1/4 divider.
OR
2) Using one of these new motherboards that can keep the PCI/AGP asycnhronously in-spec no matter what you do with the FSB and OC to the moon (as far as RAM/CPU will allow).

Does Rambus and Intel motherboards allow for a 133 with a 1/4 divider?? I understood that in order to run 133 you'd still be using a 1/3 divider (since Rambus defaults at 100x4 channels).
You probably know more than me, but if you're right, those examples are probably the way to go ;)
Northwood is a very good overclocker here check this out and this is air cooled to northwood (http://www.vr-zone.com/reviews/Intel/P4-Northwood/page4.htm)

now that's what I'm talking about! 2600+MHz rules!!!

until we see official 133bus northwood mobos, the bottleneck in ocing is the components....

crazy japs reach 3.5, i think thats not bad for oc'ing

Damn finnish (http://www.muropaketti.com/artikkelit/cpu/northwood2200/ln2/index.phtml) got one to 3.63 (stable), 3.67 post :p

Do you guys/gals see anything in the near future that will bring down the price of the 2.2?
I'm ready to pull the trigger, but don't want to waste money if there is an expected price cut, that I know nothing about.... :eek:

I'm betting the 2.4 or 2.5 will be out in a few months, and maybe a 2.7 by the end of the year.
Kool_aid, traditionally Intel does price reductions on a quarterly basis. The next announced price cuts are due at the end of the month. Often there is about a week lag while the retailers reduce their prices to reflect this, so you might consider waiting until at least earlier February to see how much the Northwood prices go down during this quarterly price cut. Like was mentioned, as soon as the faster Northwood CPUs are introduced, the 2.0 and 2.2 gig units will really fall in price too.

You probably know more than me, but if you're right, those examples are probably the way to go ;) Yes every board I've seen, whether i850, 860, 845, Via, SiS, etc - they all had a 1/4 divider at 133. The i850 boards I have used allow fixing the pci/agp bus speed to default regardless of FSB speed which is very nice. And the northwood does overclock quite well. I have yet to see a review where 2.6 was not reached.
Hmm about the overclocking to 3.6gig.
THAT IS ABSOLUTELY NUTS,
Cooled with liquid nitrogen and -196 Celius!
Whoa :)
The DDR chipset motherboards are looking good as I believe TC has the Asus board, and the same ram as to their rig.

So which of the current Northwood's is going to be best for OC to 133 FSB? WIth Samsung PC800 RDRAM will you actually be running the RAM at 533 or will you have to change the multiplier to get 399 Mhz to keep it in spec?
Merlin you can't change the multiplier on Intel systems.
And yes the memory will be overclocked to 533.
By the way on the pictures of the Northwood clocked to 3.6.
Where is the IDE cables to the hard drive?

I would say the 2GHz part with some good cooling would be the best bet. Might need a board with better than average core voltage offerings such as the Epox 4SDA. I should have my 2.2 piece next week and I'm going to use a swiftech mcx478 with it. I'll post my luck with it. You can change the memory speed to run 400 at 133, but I haven't come across any good quality rdram that wasn't capable of 533.
I've heard lots of great success stories using Samsung PC800 RDRAM, so that's what I just got delivered today. Not sure I would trust generic RDRAM though. Later on this spring, they will officially introduce PC1066 RDRAM. Now that should kick hinny for overclocking.
Well TC, you just ordered the 2.2 Northie and I'm sending out a money order tomorrow for a 2.0a, so we'll soon see how real life overclocking of these puppies works out. I sure hope they live up to all the hype. While I'll be mighty pleased with at least 2.5 gig, I'm secretly hoping for 135 FSB (2.7 gig).

Back when I had an engineering sample to play with I experimented with the ram. I was able to get Samsung up to 133 with cool conditions. Those were also the first sticks of rdram I bought. The yields have only gotten better since then. You might want to look back at this article:

Lets plan on comparing our two parts and let everybody know how much if any overclocking difference there is between the two speed grades.

Well I'll put my money on it that you'll be able to hit at least 2.5 gig. As for 2.7, I think your a guru at this sport and you'll be able to get it to that speed sometime soon but we'll see what you can get for now. Where you buying your 2.0a from? Ebay?

I'm buying my new 2.0 gig Northwood from a fellow forum member. I'm not sure if he has any more left. Hey TC, have you decided which CPU cooler you're going to be using yet? Also, didn't you have some info about VID pin wrapping the P-4 for a bit more voltage? If so, PM me, please. Yes, let's compare notes with our Northie projects. Good luck to both of us.
I have an Antec case with four 80mm cooling fans. I'll be using a Swifty MCX478 cooler with AS-II. The RAM is four 128 meg modules, but I'm going to make my initial overclocking attempts just using 2 sticks. I'm also planning on doing some mobo cooling mods (fan on northbridge sink and adding a sink to the clock generator chip). This should be a lot of fun.
I ordered the mcx478 also, and of course I will use ASII as well. I'll put this in a lian-li case. It doesn't have the best ventilation, but it's quiet. I'm in the middle of deciding what mobo to use. I want to get an Epox 4SDA, but they're not out yet. That would help with the voltage. The wire wrap trick is about as bad as unlocking an XP with the 478 pin chip. It wasn't too bad with the 423. I would assume the vid pin assignments are the same, but I have not looked at the new white papers.
