Need adivce on Celeron Tualatin o/c

I know my stuff can do 150 fsb stable so I'll say that first. Here's the situation.
mobo= asus tusl2-c

I am either going to get a celeron 1.0A or 1.1A. From the overclockers CPU database, I saw the 1.1A maxed at around 138 fsb on average (1518mhz). I also saw that the 1.0A maxed at a little over 140fsb on average (1400mhz+). So which would end up being faster? Should I go with the 1.1 and lose FSB but gain MHZ or the other way around? I play games and stuff if it matters. Thanks
 
I can't tell you the answer for sure but...

I'd hazard a guess and say that FSB will play a more important role for you. Especially if you are using SDRAM you will need all of the bandwidth you can possibly get with that celeron in games. You may have a great video card and a fast CPU but you will likely be memory bandwidth limited in many games. I'd take a higher FSB and lower overall Mhz in most cases.

Though you may run into issues with your PCI peripherals at higher FSB speeds. If you want to stay as "in spec" as possible you will probably want to grab the 1.1A and aim for 133Mhz FSB.

All my components on my cusl2-c run fine at 150fsb. So would you say the 1.0A? You think that would be able to get higher fsb than the 1.1 in most cases? thanks
 
If there is a larger number of entries, then overclockers.com is fairly accurate if you use the average overclocked speed. The 1.1a only has 14 entries, be careful how you interperet the data. I have had two Celeron 1.0a's, both hit over 1400MHz at 1.675v. My guess is the 1.1a will hit 1450-1500MHz, 132-136MHz fsb. As gaidin123 said, the limiting factor is gonna be memory performance on socket 370. I would gladly give up to 70MHz or so in speed for an extra 5-10MHz in fsb speed that the 1.0a offers.
 
Yup, if your components are known to work at 150Mhz then I'd definitely go for the 1.0A. You will probably have a bit more flexibility in bus speed vs. Mhz with that one. The 1.1A will probably max out in clockspeed well below the 150 mark.

Question for Rogue1979
I am thinking of getting the celeron 1.0A and o/c it. Currently I have a P3-700 at 933 - Is it worth it? I can see both have 256K cache but is the additional instructions/speed on the Tulatin worth it. Using the ABIT ST6 and want to give it a last run before I retire it.
All just for the fun of it.
 
I would suggest that you buy the 1.1A and enjoy a FSB of about 140MHz's. With my system FSB speeds of over 140MHz means that I need to lower the AGP speed and the vcard overclock among other things (like corruption of the HD). It's not worth it to run your computer everyday at that high FSB speeds...
 
Wouldn't OCing a 1.1A Cely Tualy to 1.4 FSB give a 1.54 ghz CPU OC? That sounds pretty iffy since most of them seem to hit the wall at 1.5 ghz.

I'm planning on OCing a 1.0A to 1.4 FSB and that will give a 1.4 OC, safer I'd think to shoot for. Plus, that ensures a slightly better memory bandwidth.

Richarito, can you list the typical PCI speeds at corresponding FSB speeds? 1.33, 1.40 etc... up to 1.50 gzh FSB - a short table if you will? thanks.
 
PIII Tualies hit 150 much easier than Celly Tualies. I'm running a P-IIIS at 150mhz FSB as I type this, but your best bet would be the 1.1a. You should be able to hit 137+ easy with one of those, as long as you burn it in.
 
the CUSL2/TUSL2 family has problems with cold booting, doesn't it? the voltage applied at a cold boot isn't the voltage specified in the BIOS, so i have problems getting my Celeron 1.2 to boot at above FSB 127....i've yet to try the tweaked BIOS. is there a problem with cold booting with the newer Celeron A chips?
 
One of the other members here tested a P3 Coppermine 1GHZ@1330MHz and the Celeron 1.0a @1330MHz. Both were at a 133MHz fsb and he said the Tualatin core scored 12% better. So for your P3 700@933MHz you would gain 7MHz in memory bandwidth, 467MHz in speed and the extra oomph from the data prefetch, a considerable boost. You may even hit 145MHz fsb speed and 1450MHz cpu speed.

I really think that 138-140MHz via FSB is possible with the 1.1A Celeron. At FSB speeds of 133MHz and greater everyboard uses a 1/4 divider, so:

FSB: 133 140 145 150 155
PCI: 33 35 36 38 39
 
FSB is more important fo' sho. Memory bandwidth is mucho important for games.

Either one will give you a very powerful system tho.

I have a 1.0 @ 1.4, and it roxors. Beats XP 1600 soundly and keeps up with P4 2GHz in Sisoft sandra. Want to go to 150FSB (it boots at that speed) but i am a wuss.

Good chip (and so cheap too...)
 
on my old PIII I used to run constantly ay 150mhz on a 1ghz chip. Is there something wrong/really bad doing that? Everything was at default voltage.

Richardito,

Muchas Grasias! BTW, what does this Semper Fi mean that I see you quote and on bumper stickers? Is this a foreign language? What does it mean?

Semper Fi is short for "Semper Fidelis", which means 'always faithfull' in Latin. It is also "Siempre Fiel" in Spanish.
