OCability of the 1.1A Cely Tualy, newer ones better?

[techwanabe]

I've read alot of folks talk about how the newer 1.0A Cely Tualy CPUs can OC even better than before... many reporting 1.33 ghz with stock voltage too!

With that in mind, I'm wondering if the newer 1.1A Cely Tualy's are also giving better results... I think initially the thinking was that it wasn't as likely to reach FSB133 as the 1.0A was... Has that thinking changed? Do the newer 1.1A's OC better and allow FSB133 or FSB140 readily?

I have not seen a 1.0a or a 1.1a that didn't hit 133fsb. On the other hand I am 1/3 with the cel-t 1.2GHz hitting 133fsb but they were both malays.

It seems that the glass ceiling for 1.0 and 1.1 chips is around 1.5-1.6GHz's. This is the max using the volt mod. The 1.3 may be able to hit higher speeds, like the 1.8GHz's some claim to have reached. But I haven't seen any good evidence.

the beauty of the 1.0A is that aside from the very high probability of hitting 1.33, they usually go beyond 1.4. the 815 chipset (which most people run with these things) is pretty hamstrung in the memory bandwidth department so the higher the bus speeds the better.

a rig w/ a 1.0A at 1.46 (146fsb) is going to be a good bit faster than the 1.1A at 133 (1.46), just need good pc133 that can do cas 2 at the high bus speeds.

Just picked up a pair, a 1.0A and a 1.1A to try out. Got an Asus SIS 630 board, limited o/c options. I can hit 120fsb without any vcore mods on both. What mobo are people running? I bought the Asus for a base for a surfer for mother-in-law, so it fills the bill quite nicely with on board everything. Just thought I would play with the combo to see what it'll do...

I'm using an ABIT VH6T mobo myself. Just do the wire trip and pump 1.8v to that CPU and it'll really scream! Mine does all the way to 1.53GHz.

I'm probably going to go with the ABIT ST6 mobo... Oldfart concurs that is should be a good OC mobo for the Cely 1.0A. His logic is the same - better to run the 1.0A at a higher FSB to help make up for the bandwidth disadvantage, than run the 1.1A up to the same CPU speed. My only concern is I want to use the existing memory I have and I'm not sure what it will do FSB wise:

1 - 128 stick PC133 Micron 7.5 ns
2 x 128 sticks PC133 Kinston Value RAM 7.5 ns

you are definitely rolling the dice w/ 3 sticks like that, although if the kingston has infineon chips it should do well. you shall see.

With those sticks of RAM, you should be able to do 150mhz FSB barrier on a C1.0A. Try upping the FSB with all of your RAM sticks. If it gets flakey, try in different arrangement of placing the RAM sticks or try em in fewer sticks i.e. 1 stick or 2. Play with RAM sticks till you get the best result in OC. Have fun.
