Which mobo for celeron 1.2 ?

[maxleo]

Hi

I have an 'old' Asus P2B which i wanted upgrade to celi 1.2 until yesterday with powerleap (http://www.powerleap.com/Products/iP3T.htm), but now seems off. not to be compatible.. :-(

Now i look for new mobo for the 1.2 celi, if possible good to overclock to 1.5 without cooling spec. fan etc. How is Asus TUV 4X? (TUSL2 has just 512Memory)

Thanks all for you input!

I think Abit's ST6 and VH6T should do the job for you. You will have to do a 'wire' trick to get the default voltages higher. There's no way to get to 1.5ghz without extra voltage and a decent cooler.

Dude do a search. I use the ST6 and it is a great board. There are some others out there though I am sceptical of. I think the BD133u with the new bios would be decent but others here will tell you to stay away from it too. I say the St6 cause it has been for me and many others a very stable board. We have a discussion going aboutthe TUSL2 and possible problems it has. Before we figure out them for sure best not order it. The ST6 will do all you need plus it has beeter OC'n needs like a 1/4 divider under 133fsb.

I recently mated a 1.2 GHz Taulatin Celeron to an Abit ST6. With the core voltage set at 1.600 Volts, the chip runs completely stable with a FSB of 125 MHz (1.5 GHz internal). Both Seti and the 3dMark software appear to run without problems.

I did find the that the integrated audio noticeably distorts with a 112 MHz FSB. At 120 MHz the audio crashes and is not functional. I solved the problem by disabling the internal audio via the BIOS and using a Creative Labs Live sound card instead.

The ST6 was shipped (last week) without the latest bios. It must be flashed with the latest BIOS for it to properly recognize the Taulatin CPU. It will light off with the older BIOS but it thinks a 300 MHz chip is being used.

At 1.2 GHz/1.475 volts the chip runs at 110 degrees F. At 1.5 GHz/1.600 Volts it runs at 120 degrees F (Temps peak at 129). You must specify to the software monitoring the hardware (e.g. hMonitor) that the CPU temp sensor is a "PII Diode" and not a thermistor. If the wrong sensor is specified you will see erroneous temps about 163 degrees F. BTW, I did not remove the IHS and have no real plan to do so (at least not in the near future).

One other thing about the ST6. I have a full compliment of cards (modem, sound, scsci, video capture, NIC, and graphics). In the past it was always a nightmare from hell getting the cards in the right PCI slots so they would all peacefully share the limited available IRQs. With the ST6 I simply plugged the cards in in the order I reached for them and everything functioned perfectly. I do not know if the ST6 is to be thanked for this excellent managment of IRQs or if Windows XP is the hero. Maybe it is the combination of both. In any case the ST6 was the easiest Mobo to install of all that I have previously used.

Pinky, I do not agree that the "wire trick" is necessary for 1.5 GHz. Please see my post above. I did replace the Intel HS/Fan with a somewhat more robust Alpha unit. However, I am running at the unmodified mobo max of 1.600 volts without any indication of instability.

In probably 75% of the cases you will not need vcores above 1.6v to hit what you did. Are you are still running the dividers at 1/3? I did the saem thing anyway cause the sb live is a better card than the onboard ac97 stuff they have. Works great if you disable the sound in the bios and add your own card. I noticed the problem happening when my fsb was around 150MHz and PCIU was around 38MHz. Chances are though you may be able to get them to work and clock higher if you use your 1/4 dividers but you may not either. Without really good cooling I would not try anything higher than 1.8v max.

Hey rhox I just checked your temps and I think that is one of your your problems with clocking higher. You want to stay around 40 deg. C with this chip as has been my experience after two of them. It seems you have a decent enough of a chip that you shouldn't need to remove the IHS to hit 1600MHz but you do need a better cooler. Anything around or above 50 deg. C is way too much and a increase in room temp could be enough to crash your system.

thank you all; i feel very stupid as so many board and chips are now around. One more such stupid question: does ddr make sense with this celeron? So no need to look at ddr-boards (f.i. asus TUA266, CUV266)? Did i see rigth this abit st6 has max. 512mb? then would tend to the mentionend h6t as i use linux which likes memory rsp. uses it as cache. Thanks again, &cheers max

Nah, IMO. You won't see performance gains unless you manage to hit some insane FSB speeds.

You're right about the 512 MByte limitation (not the fault of the ST6, it's a limitation of Intel's Solano chipset). You can get more than that with a SiS or VIA chipset board. There are plenty of boards around with a VIA chipset, the only one I know with the very promising SiS chipset is made by ECS. Very cheap and fast board, but from what I've read it's super picky WRT to DDR RAM, and ECS' BIOS programming has been only so so in the past (ever tried to get a SCSI HAB working in a K7S5A? :( ).

Ol'Man, thanks for your thoughts on the temps. I did not mention that these temps are with a case interior temp of about 90 degrees F (32 C). I am measuring the temperature directly at the intake of the fan on the CPU cooler. I am curious what you feel a reasonable case temp is.

I am using both forced and induced draft on the case. I could probably lower the temp more with higher capacity fans but I also want to minimize the background noise of the fans.

You also may be right that an increase in room temp could crash the system. I live in Florida and run the A/C most of the time but set it back when we leave the house. I did have a crash a few days ago with an elevated ambient but it might have also been due to an unrelated problem I resolved.

I am thinking you are going to start seeing more of those crashes if you don't find a way to get your temps down. Heat kills this chip guarenteed as with any chip.

[kaikara]

never say never. I just got two systems here at work with 1.2 celerons in them with stock cooling. Both will do 1.5ghz with no voltage mods or extra cooling. From what i see the temps are in the 40's but a slightly higher end heatsink will fix that.

Actually one will boot at 133mhz FSB - 12 x 133 = 1.6ghz. It crashes on entry into windows though. I would assume with a slightly higher voltage and better cooler 1.6 or higher may be possible. If it was my own i would take it higher but I don't want screw too much with something that is not mine.

oh at 1.5ghz i loaded XP and did entire setup. Did some Sisoft benching. It was rock solid - no crashes. For a fraction of the price that thing smacks around the 1.6ghz P4 and rivals a 1.8 or 2.0 ghz p4.

Are ALL Celeron 1.2Gigs Tualatin Core?
I found one online, but it says 'Celeron II - Copermine Core 1.2GHz' in the decription... Just wanna make sure I don't get the wrong one...
Thanks
John

[maxleo]

@kaikara which mobos?.. thanks! ..and does 'stock cooling' mean standard celi-added-cooler? max

[kaikara]

It has the ASUS TUSL2-C with the Intel 815EP chipset. Doesn't look like much of an overclockers board though. No voltage adjustment for the chip that i saw although i didn't look very hard as I didn't want to up the core voltage anyways.

As for the HSF - just the one that comes with the retail chip. Not very heavy duty.

From what it says on Intels site all 1.2ghz celerons are the .13 micron process Tualatin core. I couldn't find anything that said they made a 1.2ghz celeron under the old .18 process.

thanks, i think too 1.5 is enough and what you say, solid without work and think too price-performance is very ok. who knows, maybe there is chance for maybe 1.8 celi in future for another 100 bugs... who knows.:rolleyes:

Just hopefully you don't buy the TUSL2 right now until we all know for sure if they have problems.

I would definatly look at the ST6 it is cheaper and I have heard no complaints about this board except one couldn't get his USB mouse to quit flashing when in use or something which could have been something else. I have a USb mouse running through a PS3 adapter and it is fine.

You can get the ST6 alot of places for around $90 and the quality is high. For the price it has on board sound too but it seems at certain fsb's it will not work so best to disable it and use a different sound card if you are in those FSB ranges. You can disable it in the bios;)

Yeah at 1.6v you could even hit 1600MHz if you get a OEM chip made in the PHILLIPINES. I would check on that though before you buy that it is made in the phillipines.

@ol'man nono, as i would like more than 500 mb ram for my linux. Noone experience with asus tuv4x? (http://www.asus.com.tw/Products/Motherboard/tualatin/tuv4x/index.html)
mmm... maybe h6t yes! But first let's come weekend. Wish you good day & thanks a lot all once more max

[ol' man]

Yeah I think the VH6-T is just like the ST6 but via chipset and it can allow 1.5GB of ram. That would be alrigth I think. Not keen on via but if you have had good luck with via then so be it;)

I'm not having any problems, I think it was a good call (of a fellow senior member that recommended it for me months ago when we first got wind of the tualatins coming).

[maxleo]

what about this one?

-"Shuttle"
- FSB in 1Mhz steps 66-166 mhz..

http://www.spacewalker.com/german/faq/av18.htm

I have no idea; but why not just try..:-)

[batboy]

I'd go with either of the Abit boards mentioned (ST6 or VH6-T), best Tualatin boards for the price, no doubt about it.

The reason I recomend the ABIT boards is because I have had good luck with all three ABIT boards I have had. I didn;t have good luck with the TUSL2.

[maxleo]

Thanks for the recomm., thats why i ask actually yes. Just unfort. my pc-shop does not have abit (nor many shops here in suisse). If poss. i wanna buy all together also celi + ram, support then is easier if problems. -
this 'shuttle' by the way is very cheap, 129SFr = around 85$, onboard sound, and the 'ES'-Version has 1Hz stepping up to 166.

Thanks all of you Max
