View Full Version : The worst tualatin ever
Okay, I bought 1.3GHz Celeron Tualatin and the powerleap adapter rev.2.0. I'm using these on my Asus P2B. The processor won't be stable with 112FSB. I've tried the voltage up to 1.7, but still not stable. I have two 64meg PC100 DIMMs and one 128meg DIMM. I know the memory can handle it, because I've run those memory at 133MHz stable.
edit: After writing this post, I launched mIRC. Boom! It locked up. I was using 103FSB with 1.5volt. Something's not right because I ran my system with the 103FSB 1.5volt last night several hours of Prime95 torture test and it seemed to be stable. Could it be some other part in my system that is holding me back?

Yeah Breezs,
seems that the 1.3 T-Cel is real weak in overclocking. Mine a q205a01-0164 CELERON SL5JZ is a bad one too. It gets real hot 46°C. at 1.5v and its not too stable even at 105 :( . The 1200 is way better upto now. I might try it later, right now running at 1488 with 1.2 T-Cel.

With a 13x multiplier, the Tualatin Celeron is basically reaching its limits with the core. If you think the 1.3 Celeron is bad, just think how much worse the 1.4 could be.
The highest default clock speed Tualatin Celeron you should've gotten should've been the 1.2.
I must say though however, it looks like the chips you guys have are probably worse than other 1.3 T-Cel's I've heard about.

I've started to suspect my power supply to be one that's holding my tually back. I have a Macase 250W power supply. Volts are ok: +5V = 4,90 +3.3V = 3.45 +12V = 12.05, but because of the adapter, I can't see Vcore. That could be jumping up'n'down and could make it unstable. I can maybe borrow my fathers 300W HEC for testing if the power supply is the one to blame. I'm getting a new case soon, probably some Enlight with 300W Enlight PSU. I'll report more on Saturday or Sunday, because I'm not on my computer right now (visiting my cousin).
BTW, I would've get 1.1 or 1.2 model if my mobos bios would support those models (I know the new bios corrects this, but the time I ordered my parts I wasn't aware of the new bios).
bearulez: As you have only 200W PSU, I think you may have the same problem as I have.

DOh, the powerleap adapters have been known to only supply the chip with 1.3v~1.35v!
Yeah also 250w is not enough to push a 1600MHz CPU.
I have a 1.4GHz PIII-s tualatin and it will do 1780MHz on 1.75v.

I think that only applies to the first revision of the powerleap adapters. I have revision 2.0 which has jumpers to adjust voltage. It's adjustable from 1.0 volts to 1.8 volts.
...and my 1.3A run default v-core 1560/boxed cooler and 1599/water.
the powerleap or/and ram holding your back.
your motherboard is at fault(p2b) - not the cpu.

yes, i agree, i believe that it is the P2B at fault or the Powerleap...all other 1.3s i have heard of have at least hit 1.6GHZ...
It's not the mobos fault as I have run this mobo at 133MHz FSB stable. I still think it's the power supply.

the p2bs have been known not to play nice with tualatins...

Mine is running nice at 1.46.
@Breeze did you run it at 100FSB for a while and stress it to see if also there it's not stable all the time?
I Have same values 250V and Rev 1.02.
Finally, you may consider returning; i sent one back half year ago cause powerleap not tested p2b's that time. Via normal post not expensive UPS; money back worked well. And just order another one (give a new address:-)

test test 1234 ...
OK, now I'm 110% sure that the processor isn't the one to blame. I just tried 133MHz FSB (1733MHz) with 1.7 volts. It loaded to windows, but when I started PiFast, it hanged. I'm using the retail cooler with silicon grease. Hell, this seems to be one good overclocker. I should probably get some better cooling to get it stable.
This morning I set the fsb straight to 133MHz and It ran PiFast without crashing. I shut the computer down normally and there were no hangups this time.

PiFast time is a bit slow I think, because I got about 67 sec with 112 FSB CAS 2-2-2. This time I had to use CAS 3-3-3 because I have two PC-100 dimms in use.
This seems to be one of the best tualatins ever :D

Breez, did you do it with a different psu? , how come it worked out now ! That sounds like there s a real potential here. I better order a 350W psu today!!! :)

Nope, it's the same PSU. This mobo was originally my brothers and he said that it always had some problems with 112 FSB. 133FSB has worked fine on a Pentium2 350 running at 3x133=400MHz.
Now I'm running 1733MHz (1.7volts) with Alpha PEP66 and some Sunon fan. It's not stable as Prime95 torture test crashes and sometimes IE crashes. I think I should up the voltage to 1.75. That means more heat but what the hell, this cooler is designed for those really hot AMD Thunderbirds.
Now I put an 250Watt Enlight PSU in and it's more stable I think. But it's still not stable at 1.75volts. 3DMark crashes to desktop at the end of the first test or after loading the second test. 112FSB isn't stable with this PSU either. The volts seem to be very good with this Enlight. +5V = 4.95 +3.3V = 3.45 +12V = 12.20.
I will be checking local computer stores for a new case and psu tomorrow. It's funny that this damn big Alpha PEP66 won't fit in this case because the PSU is in front of the processor.

Ok OK OK... thanx for usefull info. Do You think I can try it as well?Mean 1.3 Tualatin to my P2B board (I have rev. 1.10 with new voltage regulator), but not with Powerleap adaptor, 'cos I have modified ASUS S370DL adaptor.... any sugestions?

I think you should try 1.1 or 1.2 (you need the new bios 1014 beta3) because getting 133MHz with 1.3 is very unlikely unless the cpu is a good overclocker (as I do have). 1.2 @ 1.6 would be nice, but thats not a 100% sure overclock either. It depends on are you going to use retail heatsink or better cooling. If retail heatsink, then I would advice getting 1.1 because that should be pretty easy to get to 133MHz FSB. But beware, no-one has tested the 1.1 model with the newest bios, but it should work with it.

Get rid of that Macase!! I couldn't get my cel1.2's to run stable@1.6 with same Macase 250W. (well they ran with winter air, but that's not good:) Just go and buy >300W some quality PSU... check the ratings b4 buying though

Ok, when they released 1014 beta 3 bios? I didn't even noticed...
Is, the P2B bios bug really fixed???
And did they add Tualatins with new stepping?

Today I ordered an Enlight 7246 case that comes with Enlight 300Watt PSU. They said I will be getting it tomorrow. Enlight PSUs are pretty good quality. I already tried the Enlight 250W and it was much more stable, but not enough. I think the 300W version will do the job.
majales: Yeah, a new bios was released few days ago. I'm using the bios right now. I don't know if they have added the new TB1 stepping, but check this thread out: http://forum.oc-forums.com/vb/showthread.php?s=&threadid=111544
