Old School Celeron 1.1A tualatin

[sparkY1000]

Just been playing around with my tualatin celeron 1.1A seen as its bleeding cold here I thought I might as well try and push it, its not exactly extreme but hey its still damn good fun!

http://valid.x86-secret.com/show_oc?id=165312

I managed to get 160MHz FSB or 1.76GHz but everytime i went to take a picture it rebooted lol! Im not sure If its the chip running out of juice as this is on stock voltage (1.5V) or the PCI bus speed being too high @40 MHz.
I am using an Intel D815EEA2 board which needless to say isnt great for overclocking so everything is done in windows using CPUFSB. I am using a very poor air cooler but with 12C ambient which helps even during pi runs it only reached 28C

Managed some superpi 1m action at 145MHz FSB (1.6GHz) This is a completely untweaked OS its for my general every day use, from what I can see on HWbot its the fastest pi1m by a celeron 1.1A by 5 seconds!



I will get some pics up shortly but at the mo i can barely feel my fingers its sooooo cold!
If anyone knows of a BSEL pin mod to trick the motherboard into giving the CPU 1.75V please post a linky or guide I am desperate to take this CPU higher I think 2GHz might be possible with a better board and more OC'ing options.

Nice old school!

[KennethChong]

Nice, I love seeing stuff like this.

BSEL manipulates FSB only. Although I get what you mean with a pinmod. If you goto intel's website and just pull up the datasheet, it'll show you all the pinouts and you can figure it out. Good luck with it. 40pci, yikes.

Here are some pictures enjoy

At about 9pm last night I decided to open my window and get my room as cold as possible, outside temp was 5C


Took the Spi1m but not by enough to make me happy!


Forgot to get a screeny of this but it was slightly faster than my run which took the record for certain


The heatsink that was on the chipset of my NF2 now resides on the chipset of the D815EEA2 with a little help from some thermal epoxy


Temperature in my room right next to the rig


And the best shot of them all (unfortunately forgot to take flash off but u can just make it out)

Sweet!

[Turrican]

good work, i love old skool

[Gebba]

nice oc !

does pentium3 have any good oc boards =/ ?

[sparkY1000]

I will try n push past 2GHz but I might need a better board, with more overclocking options.

@Turrican: What board did you use for your tualatin 1300 @2121MHz??

[jimwah]

Nice work breaking the 2-minute Pi on the celly This was an aim I had, but never quite managed it with my 1.1 tualatin. I need another half decent overclocking 370 board too, my last 370 rig got turned into an SDSL router

[ziddey]

were there any s370 boards that could lock pci? I remember there were a very few boards that had the 5 divider for 166fsb

Hmm i think ABIt is the word you are looking for.

sparkY1000:

I don't suppose you know the sSpec number do you (it should be either SL5VQ or SL5ZE)?

Or perhaps does anyone else know which of those two would/should overclock better? I realise that SL6xx would probably be better but I can't find any of those at the moment (in the UK).

[sparkY1000]

If i remember rightly its the SL5ZE

I checked HWbot this morn to see someone had already taken my super pi1m record, so with my limited knowledge of tweaking i set about making it faster



Thats a whole 10 seconds off my time!!

Old SKool owns, makes me wanna dust off the Infinity and 2600 M

@Turrican: What board did you use for your tualatin 1300 @2121MHz??

i've never had a tualatin at that speed

i think you mistook me, with this guys tualatin 1300 @ 2121
http://www.xtremesystems.org/forums/...d.php?t=123826

i only had a p4 1.6ghz willamette @ 2715

[buttercup]

If i remember rightly its the SL5ZE

Nice, thankyou

[sparkY1000]

@ Turrican: Ah that was it my apologies I thought it was you, thanks for the thread might give me ideas for a new motherboard
@ buttercup: no worries!! glad to help!

I also have some Athlon Xp-M old school power! It can do 2.7-2.8 on water and with phase should be capable of 3GHz!

I do love the old school but sometimes it becomes very apparent that its time to upgrade so not long and I will have an E4300 based rig

[oohms]

Try pinmodding for more voltage, and also try using the onboard video. Max fsb i have obtained with 815 chipset is 185 fsb on the asus CUSL

[sparkY1000]

Thats not a bad idea I will give it ago
I believe I have found the VID pin mod to increase voltage, now I just have to remove all PCI devices and hope my memory can take 160MHz+

[mup0]

I like it . It look like mine personal record





btw. at 1600Mhz i make 1MB Pi for 1min and 30sec...how much is your ram ?

[sparkY1000]

My RAM was at 3-2-2-5 I think it may do 2-2-2-5 but im not sure it will run at 145/150MHz with those timings, I have 2 sticks of 256Mb so I will try and isolate which is weaker and use the better one to go higher.
This board is extremely limited in overclocking and tweaking options (in fact there are none!) I noticed an Abit SA6-T on ebay if it stays cheap I will get it, hopefully it should be able to provide some more fun

What board were u using? I notice your PCI freq is locked?? How??
Thats a very nice overclock! almost 60%!

Hi sparky

I'm TASOS ... (the other guy on hwbot)

Very nice cpu you've got there.

Keep up the good work.

You say...your OS is not tweaked ?
Why is your allocated mem ... too low ?

[sparkY1000]

Hey TASOS,
Thats cool! It is a nice CPU but very board limited at the moment, what system are you running yours in?
Yeah I use this computer as my every day computer at the moment so the OS is completely standard, are you running with lots of tweaks?
