OK, info (for what it's worth) to ALL interested parties-

Did the mod early this A.M. Mine is different than the article, here's what I did:

1. Make SURE you pull your BIOS battery!

2. This mod is best done with the board pulled out of your case.

3. Yank the proc, HSF, etc.

4. Use a pocket knife or razor to slice a small "trench" between the 2 pinholes. I would advise temporarily wrapping a hunk of wire LIGHTLY around the 2 pins, then flip the proc & orientate it over the socket so you KNOW which holes you're going to do the surgery on.

Me, being the idiot I am, cut the wrong holes. TWICE!

5. Use a safety pin CAREFULLY to reopen the holes. Don't push down until you hit bottom, all you want to do is open the holes SLIGHTLY larger than stock.

6. Use a jeweler's or really small, extended needle nose pliers or forceps to hold, bend & cut the wire. It needs to be a horseshoe or "U" shape, and it WILL be EXTREMELY small.

7. The wire shouldn't much thicker than coarse human hair.

8. Use forceps or needlenose tweezers to drop it into the socket. You can use whatever it takes to press & seat it.

9. Use a HIGH POWER magnifying glass to ensure it's seated & won't touch ANY other pins.

10. Reseat your proc. Be CAREFUL, if it won't seat using normal pressure, you need to open the pinholes more or your wire is too long & not flush with the holes.

11. I would NOT recommend using the stock HSF after this mod. I changed out to the AVC Sunflower: http://www.overclockers.com/articles523/
Compared to the retail HSF, it's louder than hell & irritating as hell. It will be the price you pay for this mod.

12. Boot up, reset all your BIOS tweaks, check your temps & vCore in BIOS. Mine runs 1.68V after the mod. On first boot it defaulted to 1.85V, so you NEED to drop it IMMEDIATELY!

13. My temps are 31'C idle in BIOS. The Abit TH7 II at the same vCore was running 46'C in BIOS, using the same proc & HSF.

14. Unless you have an EXTREMELY sweet chip & monster cooling, this is NO guarantee to hit 133+FSB. What it DID do is eliminate the "cold boot" issue on my proc since it believes it's default vCore is now 1.70V.

15. vCore options go WAAAY up to 1.85V+. If you have the balls & cooling, go for it. I don't.

Benchies to follow, I ended up having to re-Ghost because my SCSI drives puked at 130+FSB.

Good luck to all who try this...

Why don't you try using the Intel stock fan? I know I read somewhere about someone doing it, I just can't remember where.

I know I've asked you this a few times before, but..

With the latest BIOS, does the P4T-E have a 1/4 PCI divider at 133MHz?

Phalanx-

I just don't feel the stock HSF has enough capacity at the new voltages when the proc is run hard at warm temps. It might, but I would rather be safe than sorry.

It's actually much quieter with my case cover back on. Still considerably noiser than stock, but livable...

I don't know if it will go 1/4 at 133. When I get more time & a spare proc I'll try it. I can't risk these drives & this rig has to pull it's share of daily work, more so because that f*cking dually has been puking...

Gotta figure a rock solid 25% OC, air cooled, first stepping at +10% vCore over stock ain't bad. The bonus is ALL my SCSI devices are hanging tough at these speeds, & the RAID array is REALLY, REALLY fast running so far out of spec.

:)

Understood.

"I don't know if it will go 1/4 at 133. When I get more time & a spare proc I'll try it. I can't risk these drives & this rig has to pull it's share of daily work, more so because that f*cking dually has been puking..."

Fair enough. I'll check with AsusUK over at AsusBoards (it's been down for a little while, no?). Sorry about the dually, what's wrong with it, BTW?

"Gotta figure a rock solid 25% OC, air cooled, first stepping at +10% vCore over stock ain't bad."

That's not bad at all. Can't wait for the next stepping(s). :)

"The bonus is ALL my SCSI devices are hanging tough at these speeds, & the RAID array is REALLY, REALLY fast running so far out of spec."

Heh, lucky you.

Temps are running about where they did using the stock HSF before mod, so I think it was a wise move on the AVC.

Dunno what the hell is wrong, don't really care enough about it: http://forums.delphiforums.com/maxcommport/messages?msg=119828.20

ATTO & HD Tach both went up a hair, it's pulling almost 104MB/sec sustained in HD Tach & 103MB/sec writes/120+MB/sec reads in ATTO.

HD Tach: http://photos.yahoo.com/bc/hyperfish1/vwp?.dir=/Hyperfish+P4+Northwood+Project/Hyperfish+P4+Northwood+Project&.dnm=HD-Tach-125FSB.gif&.src=ph&.view=t&.hires=t

ATTO: http://photos.yahoo.com/bc/hyperfish1/vwp?.dir=/Hyperfish+P4+Northwood+Project/Hyperfish+P4+Northwood+Project&.dnm=ATTO-125FSB.gif&.src=ph&.view=t&.hires=t

I think the spikes in HD Tach are error correction & temp calibration. Seagate says they have some sort of temp calibration in the X15 36LP firmware the cycles every few seconds that will cause the spikes...

I have someone asking me to build a new PC for them, and chances are it won't be an nForce PC, as much as I like it. As much as I've pushed the Sunflower, I've noticed that the Swiftech MCX478 used 80mm fans and performs quite well. Plus, I can customize the fan choice for his needs/wants. I may spend (his) extra dough on this. We'll see.

As for your dually, what do you have planned for it? Strip it and sell it? Or just keep it as is?

"Seagate says they have some sort of temp calibration in the X15 36LP firmware the cycles every few seconds that will cause the spikes..."

Well, isn't that interesting?

Dunno on the Swiftech Phalanx, I haven't used one on a P4 application.
One BIG difference on the AVC or probably any copperbottom HS vs. the stock one is how quickly it returns to idle temps after the load is pulled off of it.

Yup, it will probably be outta here within a couple of weeks.

Mmm, everything we've already discussed. As sweet as this proc might be, it takes a TREMENDOUS amount of vCore to get a 2.0A or better to 133+FSB. (Max of 1.85V in BIOS after mod)

RDRAM made it at 4X, my voltage regulator fluctuates so much the vCore actually runs almost .50V LESS than whatever is set in BIOS.

Pretty obvious at this point if mine needs that much juice to run it ain't worth it, at least to me. The good news is all 4 sticks of RDRAM had no prob running 4X.

If I get a chance later tonight/tomorrow I'm gonna try a slightly different approach to it...

BTW, here's some pics-

The socket & pinholes I cut: http://photos.yahoo.com/bc/hyperfish1/vwp?.dir=/P4+Wire+Trick&.dnm=S478+pinholes.jpg&.src=ph&.view=t&.hires=t

(Pic is of my TH7 II, the holes would be the same regardless of board)

What?! You don't mean .05V less, do you? Which type of power supply are you using? Enermax?

"RDRAM made it at 4X.. The good news is all 4 sticks of RDRAM had no prob running 4X."

Cool. What speed do you intend on sticking with? How stable was 133MHz?

*grin* I've been following this thread (and the other P4 OCing ones), and I have to say "Congrats" to you Hyper on a successful OC and mod. I used to solder engineering change wires onto the backs of northbridge chipsets for IBM, and I know first hand how small the parts you're dealing with can be.

Good job... damn good job.

This is the type of stuff that got me interested in hardcore PC use(abuse??) to start with, and I wish I saw more of it in the mags I subscribe to.

Raven -

Gaaaah, typo.

BIOS set at 1.85V, "real" = 1.78V - 1.81V.

125FSb is where it's happiest. About the same heat output as stock, BIOS set at 1.725V, "real" = 1.65V - 1.68V, all SCSI devices are happy, etc.

Anything more requires a massive bump in vCore, would probably run at 130FSB but my SCSI devices would have a sh*t fit. It's just nice to know the pin trick actually worked, at least it's ready to rock & roll if I run into a sweeter chip...

How much more heat was produced with this mod, do you really need the louder fan for this to be OC'ed this far? What is the furthest you would go on a stock HSF.

Side not, what is the best mobo for the 1.8 willy being OC'ed?

WK-

Temps went up about 2'C - 4'C, depending on intake air temp. The reason I changed out from stock to the AVC Sunflower was to keep that temp increase as minimal as possible, also in anticipation of upcoming suummer temps.

The stock HSF would work unless you have a proc that needs a big vCore bump. I wouldn't/didn't run it because my proc is running beyond the vCore my MOBO offered before the mod.

"...Side not, what is the best mobo for the 1.8 willy being OC'ed?..."

Whole lotta choices, just depends on what YOU want. DDR = whoknowswhat, there's tons of options. RDRAM = P4T-E or the Abit TH7 II.

thanks, my brother has the 1,8 from a AliewWare rig, so he has the RDRAM already. It runs great just has the INTEL mobo and there is 0 (zero) oc options here, you cant even take advatage of the lower ram latency, these setting are not there. So uless some one makes a hacked bios fot it, we need a new mobo. Asus is my first choice so will prompt for the P4T. Thanks.

another side note, I am now using the 1012twkb2 Bios from X86 and it is doing real well , thanks for showing them to me! :)

His bios wont load the Zip 100 drive as the drive letter "B", so on latest reformat, I put old bios back than reflashed to tweaked bios when thru.
