Celeron 1.0a or 1.1a for overclocking?

I am planing on buying one of these processors but I'm stuck on which one to get. I only want to overclock to 133mhz fsb, so with that in mind, what are the chances a 1.1a would hit 133mhz FSB at 1443mhz?. Seeing as how the 1.1a costs 2 dollars more than the 1.0a, its a kinna tuff decision. Would I be better off with the 1.0a for 133mhz fsb, or would I most likely be able to hit 133mhz fsb with the 1.1a?
 
Check out the overclockers database. I have not heard of any recent 1.0 or 1.1 that did not do 133. Faced with the same decision I opted for the 1.1. There are those that prefer the 1.0 at a higher FSB to increase the relatively poor memory bandwidth but if you just want to "reclock" the CPU to 133 as you say to avoid o'erclocking the IDE/PCI/AGP and possibly having to buy PC150 RAM to reach equivalent frequencies then the 1.1 is definitely the way to go and it still has some room for a modest overclock if you want.
 
Sweet, I had a feeling the 1.1a was my best bet, but I dont want to get stuck at 100mhz fsb so I figured I would greatly decrease the chance of that happening if I went with the 1.0a. Took a look at the overclockers fourm, they call the 1.Xa celly "the best 1.5ghz chip on the market" 😀.
 
I've got my 1.0a running a rock solid 1450mhz @ Cas2-2-2-5-7 on an Asus TUSL2-C mb. It posts at 1500 but won't boot up WinXP. I'm limited to 1.675 vcore in bios, and I'm positive I could go higher if I did a voltage mod wire trick. Versus my previous P3 1ghz@1125, my 3DMark2001SE scores (Radeon 8500) jumped from 6770 to 8790. I'm very pleased with this setup.
 
I would go with the 1.0a if your board has fsb settings in between 133 and 150MHz. Simply for the fact that the 1.0a will hit at least 10 x 140, which will give your memory bandwidth a nice boost which is really needed with socket 370. If you only have a 133MHz fsb setting, go with the 1.1a, but make sure you know how to do the pin/vid wire trick.
 
but make sure you know how to do the pin/vid wire trick.

What in the world is that?, I was planing on picking up the MSI 694T (Tulitin mobo) to go along with it. I just want 133mhz fsb, dont need anything faster. I really dont like running the FSB any faster than 133, stability is key for me. I also dont want to buy any extra cooling, will the 1.1a cellerie run fine with the retail Intel HSF at 133mhz fsb?. If not then I'll go with the 1.0a at 1333, I want to keep the system VERY quite and cool as well.
 
I'm still not sure, I need help :^(. I only want to use a retail HSF so I need to know how far these things go using just the retail HSF. Someones gotta know!
 
i just bought a 1.0A. It's good enough to me to reach guaranteed 1.33G.

From what I read don't get TUSL-2. Get ABIT ST6.
 
Never heard of the Abit board, why should I get that over the MSI?, something awsomely awsome about it or something?. If someone could comment on the max clockspeed with the retail HSF that would be great.
 
Yes, the ABIT ST6 is the best. You can read about the pin mod at overclockers. Generally, voltage adjustment via BIOS has been limited to .125V above default which in this case is 1.475. Doing a pin mod (shorting certain CPU pins) allows forcing a higher base voltage from which adjustment can then be made via the BIOS. The most common mod results in a default of 1.675V. However, it will not be necessary for 133MHz, especially with the ST6 who's latest BIOS now allows a higher increase .2V above default. My 1.1 required 1.525V @ 133. I am sure the Intel supplied HSF is more than adequate. I did not use it myself because I have a better one sans fan.
 
Isn't the 815EP limited to 512 megs of ram though?, I think I may buy the ST6 but seeing as how I want to use it as an FTP server when I retire it, that limit may hold me back a bit.
 
The Abit board seems to have a cas latency memory issue. The people over at the overclockers forum said it asks you to change the cas mem setting to 3 at start-up at 133mhz FSB. What exactly makes the ST6 better than any of the others Auric?
 
I was wary of the 512MB limit also but as this was planned to be a shorter term solution for me until better P4 boards were out I still preferred to get the Intel chipset rather than the VIA with higher memory capacity because the latter is generally considered not as good. If you must have it though the ABIT VH6T is still a good overclocking board and cheaper too. The ST6 is generally considered best because among the i815EP boards it has the maximum configurability. The higher priced ASUS limits the dividers at certain points. As for the ST6 CAS latency thing, it only suggests the setting on the boot screen without making changes, pausing or requiring any interaction. I do not know if it does this whenever the FSB is set to 133 or only when the memory is not rated at the settings it is run at. For instance my memory is rated at PC133 CAS3 but I run it at CAS222 5/7 so I do see it at 133 but not 100 with the same settings. Perhaps if PC133 CAS2 RAM (or better) was used it would not display? What is your take on this from what you read at overclockers? In any case, it is not really an issue.
 
I hear it happens regaurdless of the mem you use and 133. If its cas2 ram you still get a pop-up of some sort asking you to change it to 3. I am also buying this as a temp system till the right time to buy a P4 system pops up. This is why I dont want to spend the extra cash on the ST6. VIA based Intel boards have always worked very well for me. Thanks for all the input, I decided to order the 1.1a and the 649T, I'll post an update of how the combo overclocks.
