P4T-E Multiplier??????

[Big Nuttz]

Ok after really reveiwing the jumper mode settings I have a question. The jumperless mode supports 100-133 fsb. What is the pci/agp divider on that? If you look at the picture I attached 100-133 fsb circled in red the pci/agp is way too high. Is that what your setting through the BIOS?

[cw823]

if you'll notice the 133mhz settings....one has everything set way too high, and the other has it just right.

From 100-close to 133mhz FSB, the dividers are 1/3 for PCI, and 2/3 for AGP. At 133 your mobo should (if not set manually) change the PCI divider to 1/4 (133/4 = 33), and the AGP divider to 1/2 (133/2 = 66). The object is to keep both settings as close as possible to 33mhz for PCI & 66mhz for AGP.

Most times anything from 100-124 is OK for most equip...anything above and you need to jump to 133 to take advantage of lower multipliers.

[Big Nuttz]

Thanks for the reply buddy. I was wondering but that totally makes sense.:D

[chop]

That makes sense. I was wondering if I was frying my other components when I was at 133fsb.

hi
how can i change on the asus board the divider for pci and agp?
is this possible via the bios settings and if yes how?
thanks

The only way to take advantage of the 1/4 multiplier w/ the P4T-E is to use the jumper mode, not the bios. If you are over clocking via the bios, you will not get the 1/4 divider and your PCI bus will be run way out of spec.

The P4T-E does not have built in dividers to the bios. Most everyone you see w/ a P4T-E overclocked really high is using the dip-switches to achieve the overclock. Hope this helps.


p.s. I have found it much easier to overclock through the switches. All you have to do is turn your system off, open the case and change the settings like the chart that was posted earlier in this thread.

Someone try the 3rd 133FSB setting and post what they get. I got 1600mhz@133FSB.

[chop]

Which 133fsb setting would you use?

[Big Nuttz]

I myself would use the Dip switch with 33.3 PCI and 66.6 AGP. Thats just me though. Mine at 142 is at 35.5 PCI and 71 AGP.

[chop]

When you change the FSB via jumper mode, does that have any effect on your voltage settings? Can you still change the voltage settings via the bios?

[MospeadasDark]

No it doesn't change the voltage. You'll have to do a Vidpin mod for more voltage under dipswitch mode.

[JudgeDredd]

Where'd you get that multiplier chart from?

[VaTechHokies]

I believe it's from the P4T manual. Asus didn't include the dip switch settings withe P4T-E, but they are the exact same as the older mobo

Page 20 of your P4T-E manual (not P4T) is the CPU Ratio Multiplier Table which I use, but for the FSB I use the P4T manual. Hope it helps...

[VaTechHokies]

The CPU multiplier dip switches don't do anything since Intel locks the chip. It doesn't matter what settings you have for the first four switches (which as bm1 pointed out) are in the P4T-E manual. The only settings that matter are in the P4T manuel.

I'm new this... What is a "Vidpin mod"?

Thanks,

Go to the Intel CPU's section of the forums and there is a 'sticky' at the top of the page by BatBoy outlining the Pentium 4 Northwood vid pin. Bascially, you short a couple of pins on the processor by placing a copper wire strand around them. Depending on which pins you 'wrap' the core voltage of the P4 can be set anywhere from 1.7 to 1.85 volts. This is an issue with the P4T-E because when you overclock via the jumpers, you can't change the vcore via the bios, so you have to do a vid pin mod to get a voltage your comp will run stable at. Hope this helps.

P.S. I would post a direct link to the sticky, but my browser is all messed up and I can't get the intel cpu page to display properly. I think the thread is called somthing like wire wrapping the northwood.

[MospeadasDark]

Here you go, there's a new one.

Thanks.

What about the vcore settings. Can it be changed after you do the mod? Meaning... If it mod it to 1.85 and it's too hot for air cooling, do I just go in the bios and set it lower?

What are the possibilities of getting a Asus P4T-E with a 2.4 northwood, air cooled with a Sunflower to 3 GHz?

If I were you, I'd start out with lesser voltages and work my way up. I have a 2.0A at 2.72 (136 FSB) w/ 1.8v vcore. I suspect that I might even be able to get away w/ a vcore of 1.7, but I am not going to risk the wire wrap I did, as my temps are fine. What model of the 2.4 did you get? The 100 FSB or the 133 FSB? I would say either way your chances of getting 3 ghz are pretty good, as it is only a little overclock. I suspect it would be easier to reach 3.0 ghz with a 100 FSB chip because most current hardware can get up to 133 w/o any problems, its just getting past there.

As far as your question about lowering the vcore once you raise it to 1.85...I don't think you'll be able to lower it through the bios because the mobo thinks the default voltage of the processor would be 1.85. I haven't tried this either though.


Good luck in your quest for 3.0!

Thanks, I've tried getting higher than 2688 but just get a black screen and I have to power it off. I'm sure it's my agp/pci speeds but going by the chart, at 125 (where I want to be) the AGP is 83.3 and PCI is 41.7. The second 133 looks the best but I probably don't have the voltage to go there.

What model of the 2.4 did you get?
It is a 100 FSB chip.

[Link2000]

Also, where are you getting the jumper settings? Are there more than the ones pictured above?

He posted all the jumper settings for the P4T-E. I am using the 136 FSB setting which puts my pci at 34 and my agp at 68. I would try the 133 settings first though because they put your pci and agp almost exactly in spec. Keep me informed on how high you get that thing. Good luck.

p.s. You made the right choice in getting the 100 FSB chip. You should be able to get that chip flying. The 133 chips will be overclockable in a few weeks w/ the new ram, but as of right now, I haven't seen the new 133's overclocked all that much.

[Link2000]

Thanks for everyone's help. I'm doing the vcore pin mod tonight using the conductive ink. I'll let you know tomorrow how it went.

Link2000

[Link2000]

Well, I did it! It works... Well at least the pin mod works. I now have a 1.85 Vcore with an idle temp of 38C. But I still can't O/C it any higher than 115 fsb. I tried all of the 133s and just about everything inbetween. I just get the "high - low - high - low - high - low" beep codes. Not sure what that means but I have to hold down the power button to shut it down.

Please help?!

Link-
Can you list all the specs to your computer? i.e. power supply, ram (manufacturer, size, # of devices), video card, etc. It would help a little bit if we knew the specs of the system.

As far as the high low bios beeps....I am reading up on it right now in the Asus manual. I had the same thing happen to me yesterday afternoon when I bumped up my FSB to 150 and dropped the FSB multiplier to 3X. If I find anything I'll be sure to let you know.

VaTechHokies

[VaTechHokies]

Well, I just got done reading the Asus manual about bios error codes. It didn't help too much. I know what kind of beeps you are talking about, but I've attached a pic from the manual which only shows 4 different beeping codes.

If someone can step in and offer a bit of advice I'm sure link would appreciate it. Sorry I can't be of more help link :(

[Link2000]

Thanks, I'm calling Asus today to ask them about the beep codes and I'll let you know.

My specs are:

Asus P4T-E
Intel P4 2.4 100 Northwood
AVC Sunflower air cooler
Antec 650 case with 350w + 3 80mm 40cfm case fans
Corsair PC800 RDRAM
Nvidia GeForce 3 Ti500
Audigy sound card
Intel Pro100+ Server NIC
3 80GB Harddrives
Plextor 12/10/32a writer

Thanks,

Ok, just got off the phone with Asus. They said that the beep code means one of three things: Temp to hot (not the problem), voltage too low or voltage too high. I don't think the voltage could be too high at the 133 fsb because I run with the same vcore at 115 fsb. So, does this mean that the 133 fsb needs a vcore higher than 1.85?

hi!

i tried out the dip setting with using 133 mhz fsb and everythings fine, except some sporadic booting problems i got two times a week. windows says that it can't load some drivers because of a corrupt file on the disc. as soon as i take the fsb back to 100 mhz it works without problems and without any change to the files itself!

does anyone else has this problem and maybe solved it?

here's my rig:

p4t-e
p1.6a
2 x 256 MB Samsung RIMM
matrox g550
maxtor 80 gb
