[OLD SCHOOL]pentium mmx166@420 mhz and tualatin 1300@ 2388 mhz ln2

**ruggero** · 03-23-2009, 12:43 PM

Hi boys,

my first bench with ln2 and with my dewar homemade(50€).

The dewar

The cpu,pentium ultra mega super core mmx166

And the score,no cpu-z because the p5a have more problems with pci;cold bug around -140°

http://www.youtube.com/watch?v=NUuS2...layer_embedded

Another two little score

Cuv266 and mendocino 300@733mhz 2,4volt -120°

http://valid.canardpc.com/show_oc.php?id=531602

tusl2-c and celeron 1300@2388mhz

-190°,no mod(there is a mod for the vcore?)

PS:next week,superpi with pentium mmx sub 7s

Very thank's to abo for the setfsb cuv266

sick retro clocking lol. But your dewar is going to haunt me until my dying days man.....creepy. Reminds me of the dude behind the dumpster in the movie Mulholland Drive

awesome!!!
sub 7 minutes? LOLOLOL

congrats!

**[XC] Oj101** · 03-23-2009, 01:00 PM

That is sersiously cool! I didn't know the P1 had so much in it. I thought my P200 (66*3) at 300MHz 24/7 on stock cooling was extreme :p

**FlanK3r** · 03-23-2009, 02:04 PM

can u try some benchmarks? Nice temp

and nice clock.

**cdawall** · 03-23-2009, 02:44 PM

you made my day a little better lol pics of the custom pot?

**sparkY1000** · 03-24-2009, 08:57 AM

Fantastic achievement with the Tualatin! There most definetly is a Vcore mod for the CUV266 as I have it on mine at home think the reg allows upto 3.5V Vcore but I wouldn't like to try it. Im away at the moment so I haven't got any other details but the mod is definetly possible!

What hard drive are you using wtih 46MHz PCI frequency? Or are you using a 64bit PCI IDE card?

Cant wait to see you pi1m time for the 1300! Congrats again!

this is the first section with ln2,for me is a good result don't broken anythink.

Next time I will try superpi 1M with the mmx

Thank's but is not a fantastic score,is a wr for a celeron 1300 but more is possible.

With 2 volt and a tb1 I think a shoot@2550mhz is possible.

My friend stalker170 have the tb1,but where is the mod for vcore of tusl2-c?

I search for vmod of my tusl2c,not cuv266,my cuv266 is perfect(201 fsb

).

47 of pci is not a problem,look this picture
60 mhz of pci western digital 8 gb

PS:where is the vmod for tusl2c?

help me boys

**bartx** · 03-24-2009, 12:04 PM

I had this board some time ago - vcore controller is on 95% located between socket and top edge of board. Check the markings and find datasheet of this part in google (I haven't found any schematics for vmod on this board). Then look for fb pin, check resistance between this pin and ground and try to find place, where you can solder wire. Paste pics in good res in this topic, I'll try to find it also

And finally - nice results

**Morais** · 03-24-2009, 12:20 PM

Nice results, remember my old coppermine celeron.
Here it is, socket 370 pin mod

Not for this board - 1,8V is maximum, more only with vmod, I've tested that pinmod also

**tiborrr** · 03-24-2009, 12:54 PM

Ruggero, you rock, i just love this kind of overclocking! Congrats!

**wittekakker** · 03-24-2009, 12:59 PM

Sure P1 can boot 400MHz with LN2, though it's the boards that limit the oc, call yourself a champ if you get anything over 350MHz working in windows

PS: I think there is a tusl2c vmod out there, or maybe I'm confused with cucl2c?

what you used to cool the cpu

**sparkY1000** · 03-24-2009, 11:55 PM

Ah my apologies I see now in your OP (d'oh)
That is a fantastic FSB out of your CUV266 mine falls over every time around 166-167MHz FSB, not sure if its my hard drive flaking out or the board not being up to it, any ideas? Have you tried modifying the socket to accept Tualatin core so you dont need TUSL2-C?

I think at home I have Celeron 1000 (possibly ES), 2-3x 1100, 1-2x 1200, 1300 tB1 & 2x 1400 tB1, just need time to play with them all

Good luck with the mods, would like to see what you can get out of a PIII-S 1.4! I am sure sub 60s pi1m is possible with Tualatin

**[XC] Oj101** · 03-25-2009, 12:18 AM

I want pictures of the rigs

My cyv266 shoot at 201 fsb(very thank's to abo

)no mod and all stock cooling

http://valid.canardpc.com/show_oc.php?id=521629

this is a photo of my tusl2-c,the microchip is ISL 6524cb P0127ADT3

I think for tualatin tusl2-c with vmod is the best,for this i search for a mod

PS:I have a pentium III-s 1.4

I search for only a celeron 1400 tb1.

PS2:there is a mainboard with chipset apollo pro133a over 200fsb?

**saaya** · 03-25-2009, 02:04 AM

hahahah awesome! i always loved pushing old hardware to the max

amazing bang for the bug and its all about fun anyways since its so slow and crappy ^^

nice!

the dewar... lol... wtf???

**ilkkahy** · 03-25-2009, 02:22 AM

Back in the day i had pentium mmx 166mhz and i gotta say 166@420mhz is just crasy... Good stuff

**[XC] gomeler** · 03-25-2009, 10:43 AM

is that dewar some sort of drum coated in insulation?! Hilariously dangerous

**Odium** · 03-25-2009, 11:01 AM

Simply amazing!

**ruggero** · 03-25-2009, 11:08 AM

photo of my dewar with 50€

**vservera** · 03-25-2009, 11:47 AM

nice work m8 !

**sparkY1000** · 03-25-2009, 12:41 PM

Very interesting Dewar, you are a brave man!

I am going to try a different hard drive with my CUV266 and see if I can get any further, failing that I may have to track down a TUSL2-C to see if I can give you and Stalker170 some competition
