1: (Need to check this)
==============================================================================================
2: 90MHz 80Mhz
==============================================================================================
3: RU
==============================================================================================
4: Globalwin Fop32/38 Heatsinks with the fans off my Xeon wind tunnels (60mm 6000RPM ish) and a 486 fan on the chipset. The room was cold as the window was open, and the bios showed the temps to be 26degC, May look at water cooling if it was the cold room which helped make it post at this speed.
Intel P3 heatsinks and fans, but might go back to the above setup soon.
==============================================================================================
5: (Need to check this as well)
==============================================================================================
6: EC10
==============================================================================================
7: Windows 2000 Pro. I don’t know if it will boot into windows yet as it corrupted the install at a lower fsb when the PCI bus speed didn’t agree with the controller. I think it was when it was at 40 or 42 ish, but it booted to the same point it would boot to at standard speed... I'll cross my fingers and hope it works better tonight. after reinstalling.
Mandrake 10

It also posted at 91 and 92fsb but crashed when detecting the drives, I would up the voltage a little more but I’m at the current max (2.3V) but I’ve read some where on here that this can be increased, Ill have to go find that next. (Not sure on trying higher voltage what is the highest people have gone?)

2 years ago these chips would only just post at 600, so I’m not sure if its because it has so little hardware in compared to what it had in back then or if its just that the chips have been burnt in more.

Another thing I noticed, as soon as I went over 600Mhz, the bios still showed it as 600Mhz until I hit 650Mhz then it stayed at that from then on, is there any way to fix this?

Only other thing I have to say is wahoo! As I wasn’t expecting to get them this high.

hahah

i've not had mine abover 600mhz myself

i keep them at 585mhz atm

they seem to run really good

Update.
I have made amendments to the above post.

Will still post at the stupid speeds easily, but can’t get it to boot into an OS at any speed over 600 as the harddrive controler doesn't like it.

Tonight I shall try running it off a cd at the higher speeds.

They were running at 600 most of last night, and I hope they are still running now as I left the machine running boinc.

I have also changed the heatsinks to the Stock ones off some P3 chips as the other ones were too noisy, but now things are a little hot, the temps are about 50 ish

change controller card. I use promise ATA133TX2 atm and it would perform just suberb at 91MHz FSB, which is 45.5 for PCI.

if you wanna hit high with your jackpot celerons...

watercooling with good blocks and system in general and you will be 650MHz+
TEC with 2x226W or even mentioned 2x274W - 5x5cm - you will be high into 800MHz+ and that is true cause with only 2x127W you should hit into 700-750MHz.

At that speed for the north not becoming the bottleneck, I would suggest TEC+water for the BXie.

Just remember to insulate well also the back of the board, if you decide hitting the jack.

for the voltage, me myself tried at 2.45V, though I could not get more due to cheap PSU and maybe also due to voltage regulators not being able to suplly enough current at that voltage and above. there is a software jack, but it does not work everytime you do it, you have to power off completely, even from the plug after you do it and it is not after everytime... but it is doable. I would prefer now a hardware hack. I think you should change voltage regulators if you wanna anything into 2.6V+

If you go that high with voltage... that would ONLY be safe with TECs+water and powerful TECs...

I am attaching the program for the voltage, but changing to jpg. when downloaded, just rename to .zip and that's all

I am attaching here few screenshots form the times before, when i had problems with cheap 250W PSU on 3.3V line on BP6, then I have spliced manually ATX cables with the other 200W ATX and got the result you will se here. also I was able to boot at 2.45V

what's going on here? I got distracted by the wallpaper

looks like you used a uni366 sometimes and dual366 others. did you try with lower voltage. i learned from kuun's various posts that 1.8 is usable sometimes even with overclocking.
my own tests it looks like when a chip needs higher voltage(then 2.0) for stability the chip is very near its limits and for each .1v gives diminished speed gains. im running a uni366@506 at 1.9v. unstable at 550 even at 2.1v.
what do you think?
btw, in my opinion, a system doesn't get credit for "running" at any speed unless it can boot to the OS and you can at least play a simple game.

High voltage would be good for him if he goes TECway - it would help to reach that sweet limit safely.

In my opinion when you start raisng the voltage that is not the chip on its limit, but the chip on its limit with current coling system

yes you start getting diminishing returns. I was able to be 24/7 stable (and that is the only credit speedfor me) at 366@550 at 1.9V and 366@574 2.1V. Anything above is not stable with those celies with air. was able to bot at 610Mhz but that was in chilly winter with window open and nothing more.

Cheers!

um if you were 24/7 then who is 24seven

...im so confused...
HAHAHAHA

btw, kool pics.

24seven,
your opening post is great and well organized.
