squeezed some more out of my P-III 700

[batboy]

Ok, I gotta brag a little. The weather has been cool here lately. Today the ambient temp was 20 degrees, so I decided to make a maximum effort on this 700 chip. I get to change my signature again.

Got my sweet machine to purr at 1085 MHz by raising the FSB to 155 MHz and by bumping voltage up to 2.0, plus setting the RAM to CAS3. I was finally able to run the Unreal demo loop and benchmark with 3Dmark2000.

Next, I tried 157 FSB and was treated to the boot screen proudly showing 1100 MHz. When Windows started I got registry errors, I tried 2.05v and got it to run about 20 seconds before crashing.

Hmmm, I wonder if water cooling is the way to go. I decided that 2.0v was my limit with air cooling. I should be happy with what I have, but I can't help wonder how much is left in this combo and chip.

Well, a tweakers work is never done, eh?

Just checking out my new signature. Cool.

that kicks ass for a p3 700, my friends would only go to 966 and he had more cooling than you do.

hey man thats awesome, good to hear it.

I have mine running at 1050mhz 1.85v but will run at 1.75v just bumped it up just incase... as soon as I hit 157 my hard drive scrables as well, so I have to keep it below that till I get a better hard drive.

All I have for cooling is a pulled celly hs with my powerleap adapter fan over volted to 12v.. loud but cools like a bitch.
generaly around 32* every time I check.

I think if I went watter cooling and a new hard drive I might beable to hit 1200mhz.

Maybe you should try that aswell.

I have a p3 700E cCO Mayla chip, how about you?

The trouble is with a P-III 700 anything above 157 FSB, even with a 1/4 divider, causes the PCI bus to run too fast, then I have card and controller instability problems. So in my case, 1.1 gig is probably a more realistic maximum, especially since I'll probably need at least 2.1v just to even run at at that speed.

But, water cooling has been catching my attention. I have an extra car heater core and a new tranny cooler. Mainly just need the water block, pump, and tubing. Maybe a good "heat of the summer" project for later on. Also, I might keep my eyes open for a nice cheap cD0 P-III 800 to play with, maybe that would make 1.2 gig if watered down..

Congratulations, Batboy. That is a great overclock. :)

well.. for me, I decided to just sit where Im at. I think 1071 is enough for me to run all games solid. My Abit BE6-2 is pretty much maxing out in the northbridge department cauze the AGP is topped out at 2/3 ratio.
Im happy where Im at. :)

BatBoy, CONGRATS on the OvrClock!!!
i've got a pentium111 800EB and i have JUST squeezed a bit more outa my baby 2, the ONLY thing holding me back is my Nvidia TNT2 M64 32MB video card, other wise im sure that i could get more outa this mammy jammy. below is a link to my web site with a JPG of my WCPUID statistics.....also my recently finished and proudly done cooling MODS and case manicure (painted). =)

Hi batboy,
I have Abit sa6 (almost like yours sa6r), PIII 700 (100 Mhz FSB), Golden orb amd PC133 RAM.But I never get more than 128 fsb stable.I read that i815EP do not work with PIII(100 Mhz FSB) and PC133.
Can you help mi get better.

Anyone have any info regarding the new cd0 stepping pentium 3's?? I hear they use, FC-PGA2, but will still work on existing socket370 boards...... is that a true dat, or f**k dat? :)

[DocClock aka MadClocker]

First congrats, Batboy. but I would think if you could run at say 1050 cas2 your benchies would show a big difference. I use Mushkin rev2 and rev3, and am able to run at160cas2, but I don't have enough cooling for this chip..(air only).
Secondly I hate to tell u this, but the smallest DO will be 866, or 966,and up, and to answer the other question, I was reading a thread (thanks ED )on another forum, where a supposed intel tech said the fcpga2 is the same form factor, and most 815 boards should be able to handle fcpga2 with a bios upgrade.
look on the main page for "intel news" it says something about tualitin

ERRR!!!

And I cant run my 800E any higher then 1008 without loosing stability! And my cpu temps are 9c @ idle and 20c @ full load. I wish I would have gotten a socket 370 board and cpu or a PIII 700 instead. Maybe I should buy a PIII 700 and see what happens.

anyone want to buy a slot 1 PIII 800E (cbo)? (i did't think so)

By the way awesome overclock man!

Ok, another update. This morning I opened up all the house windows and got ambient temp (room temperature) down to 18 degrees C. Next, I left the computer sides off and pointed an AC fan directly at the innards. Then I tried 157 FSB again using 2.1 volts (I have the CPU VID pins wired). Now I can get it to boot and start Windows, yippee. I almost climaxed looking at the 1.1 gig Sandra CPU benchmark. Unfortunately, it really isn't stable at all and won't do any 3D games or 3Dmark2000 benchmarking without crashing back to the desktop. Voltage is way higher than I like, temps are borderline hot, and the PCI bus speed is running in hyperdrive. I think for all practical purposes, I slammed up against "the overclocking wall". It doesn't matter, I'm very pleased with the results. I just knew there was a little extra left in this exceptional P-III 700 processor.

QC, there are several things that you can try and tweak to improve performance on your machine. I'm constantly trying different cooling mods and tweaking stuff. The SA6 is a good stable board and really you should make it to 133 FSB with that P-III 700 chip for at least 933 MHz. First thing I see holding you back is cooling. The Golden Orb is about at it's cooling limit and probably should be the first thing to be replaced. You'll also need to add at least one 80mm front case intake fan and another rear exhaust fan. All the wires and flat cables in the case should be rerouted, taped, or tucked up out of the way for better air circulation (free cooling mod that really works). If you haven't put a 40mm fan onto your motherboard's northbridge "greenie" heatsink, then try that too. A recycled 486 CPU fan works perfect if you find the right size screws. The other thing is RAM memory settings. Try using the Soft Menu settings of (4:3:1) when you're trying different FSB speeds. This runs your RAM at a 3/4 divider, so if your memory can't run at full speed and is holding you back, you should have success now. In my case, my PC-150 RAM would not run above 153 FSB unless I used the CAS3 timing setting. Lots of things to try and do. That SA6 and P-III 700 combo is just waiting for you to give it some nice lovin'. Caress and sweet talk that system. Buy it some cooling trinkets, spend some quality time together, show your computer that you really do care. She will put out for you, you just have to romance her a little.

Aeon, what I've hearing is that the P-III cD0 stepping will work on existing chipsets, but the new P-III Tualatin 0.13 micron CPU will not.

Good deal, Batboy!!

I just got an air conditioner for the window in my computer room. The way our apartment is designed, there's not much air circulation thru this room, ...we could have the AC on in the living and bedrooms and it's still about 15-25 degrees (F) hotter in the PC room.

Can't wait for the first day the wife works, and I don't...hehehehe gonna shut the door to the PC room, crank up the AC, and get the ambiant temp down to like 50 degrees F.....see if I can get that last 8 MHz of FSB that way....lol

I'll take a screenshot if it makes it....1002 here I come!

Oh gawd help me! Now I have visions of peltiers and water cooling running through my head. I just read the front page article about supercooling the motherboard chipset. Initial results seem very favorable for extreme FSB speeds in the 160-170 MHz range. I can see it now, Batboy's supercooled computer running three separate TECs and water blocks on the CPU, GPU, and northbridge chip. Hoses running everywhere, a separate power supply for the peltiers and water pump. All just to reach 1.1 gig stable, which is actually only a few MHz more than I can already do with air cooling. Is this overclocking addiction a money sucking sickness or what???

I already have a new GF3 video card in the budget for the next pay check. But, now I'm looking out the front window at my poor car that needs front tires. Water cooling for the computer or a pair of new sporty tires for the ol' Grand Prix. Hmmmm. I hate it when reality gets in the way of my dreaming. Guess I'd better get the tires for the car (sigh). The computer is working ok without supercooling, but the car don't drive so good with flat tires. Maybe I need a wealthy wife. Any lonely rich widows or financially secure babes reading this forum post right now that happen to be looking for a computer geek guy?

[[OC]_SR20DE]

use the couple of spare tires, heehee~ then you can buy GF3 card now! =))
