1.2 266 bus or 1.3 200 bus

[Brandon2000]

I am getting ready to build my next system. I do have my mind set on the Iwill kk266r board. But I have a problem right now, I can find the 1.2 266 bus and the 1.3 200 bus thunderbird for about the same price $260 for the retail box. I was going to get the 1.3 but some people suggested that the 1.2 266 will overclock better, any comments or suggestions will be greatly appreciated...

If they are the same price there is probably little difference....if you assume a 15% o/c as a safe bet then the 1.3 will run faster...I hear the 1.3 are AXIA chips which are good o/c when found on a 1 GHZ....but if the chip is rated at 1.2 or 1.3 there will probably be less head room for O/Cing...the 1.3 seem to be able to reach 1.6 from reports about 20% O/C... but remember O/Cing is the luck of the draw...some chips are great others are not as good...

I would go with the 1.3 and shoot for 1.55-1.6...the 1.2 may reach 1.5 but the 1.3 will probably get there....

This is my opinion

The memory I have is a stick of Micron's 256mb pc 133 cas 2 memory and a stick of Compuwiz's famouos pc133 infineon cas 3 memory. With these two chips, would the 1.3 200 mhz bus be a wiser choice because my memory most like won't go up to 150 or 160 like most people do with their 1.2 266 mhz bus chips?

from what I have seen of compuwiz1 ram they are very good chips and often do 150 fsb and even at cas222...but the ram maybe a limiting factor...

Mixing ram in some cases can limit your fsb speed if they will not both run at same speed and some types of ram are not happy together...although my experience ..I have symax 128 mg stick and infineon stick running fine together in a second system...

In either case if the chip is unlocked as I believe all 1.2 and 1.3 ghz chips are the fsb is not as important as you can make a multiplier adjustment...
Most say the highest fsb that can be used while reaching your desired speed will give best overall system performance...

for example 1400 10 x 140 is not as "fast" overall as 9.5 x 147....but in reality the difference I think is imperceivable...but that said I run my 1.2@1406 with a 148 fsb not 10 x 140....

Thanks for your input. Here are the rest of my components, can you give me some comments on the combination here:

2 ibm 45 GB ata100 drives
TDK Velocd 12x24x32 with burnproof
Geforce 2 gladiact card
I was going to use the onboard sound for the iwill kk266r board because I have hear problems with the sblive cards with them. Thanks again...

Go with the 1.3. You can always run the 1.3 with a 133 bus to get around 1.33 im sure will not be a problem. But at that point you are really hitting the cieling for headrom on the OCing, so its gonna be completely luck. However might as well as go for the higher rated cpu and run it on a 133 bus.

<< . I was going to get the 1.3 but some people suggested that the 1.2 266 will overclock better >>



dont ever lissen to those people again, they have no clue what they are talking about. it doesnt mater what the fsb of a t-bird is, you can change that either way on the motherboard with no porblems. as for how fast your ram can go, that doesnt realy mater either. each chip will have a maximim multiplier of 12.5 and even if your ram can only do 133 and not even a hair over you could still bring ehiter chip up to 1663mhz, assuming the chip can take that. the only diffrence between the 2 chips once you have them unlocked and in the motherboard will be that the 1.3 will do at least 1.3 and stable and for all you know the 1.2 may not go to even 1.25.

Snowman,
This would seem to be a wise point. So, basically, one would do just as well to buy a 200 FSB T-Bird, in that any 200 FSB T-Bird can go 266 FSB (without strain) with adjusted Mobo settings, such as on and with the I Will KK266 ?
Again, when buying a 266 FSB mobo, one then has the option or latitude of moving a 200 FSB T-bird to 266 FSB, just with the settings in the mobo ?
And this would be a separate function from the action of O/Cing it from, lets say 1 gig to 1.2 gig, or more ?
Thanks, Ken

for me i will get the 1.33 gig the price are cheaper than 1.3gig and it can overclock bester than 1.3gig

 

[Brandon2000]

If I had an option, I would definitely go for the 1.33 266 bus thunderbirds. But the only reason I am caught between the 1.2 and the 1.3 is because they are the retail box, and I would feel safer for a 3 year warranty. Thanks for everyone's input, I think I will go with a Iwill kk266r and a 1.3 200 bus thunderbirds, thanks again, you guys are always so helpful, keep up the good work

One other thing, will anandtech's article on 133a boards have a big effect with me? Would I be able to run it at 133 bus speed or do I need to unlock the processor? Hopefully it will come unlocked...

 

[kylebisme]

eaxtly, ill give you a breef rundown of whats going on and what you should do when you get the chip. the 1.3 200 bus runs at multiplier of 13 and a front-side-bus of 100 for 1300mhz total. however, this can easly be changed by unlocking the chip and useing the multiplier and front side bus settings on your kk266r. if you move the multiplier down to 9.5 and the fsb up to 133 you get 1264mhz total. then try 10x133 for 1333mhz, it will almost defenalty work at that. next go for 10.5x133 for 1397mhz, then 11x133 for 1463, if that works go for 11.5x133 for 1531mhz andd so on untell you can no longer keep the computer stable. you will most likely have to give it more voltage eventualy, but as long as you are cooling it well it is no problem to even max out the voltage on your motherboard.


yes the anandtech artical will have an effect on you though, read through it and see what it involves. you will almost deffently have to unlock the processor and may well have to cut a bridge or two. however neither is realy a big deal.

I AM CONFUSE ABOUT YOU (Brandon2000) ARE YOU A OVERCLOCKER??? IF YES THAN WHY GET STOCK HSF TO OVERCLOCK YOUR CPU??????????????????????????????????????

 

[Brandon2000]

Just trying to gather as much info as I can before I make the purchase, not trying to offend anyone. Of course I will try to run the chip to its max but I just want to get opinions first, thanks.

If you are really interested in getting the best shot at a high overclock, go to a computer show and hand pik a chip that is AXIA. I assume that all of the 1.3GHz chips are AXIA's but I am not 100% sure - if it's true you could just order one and not have to spend the time digging through CPU trays. Also, you should buy an OEM chip. No reason to pay retail if you are just going to void the warranty and replace the standard HSF with another one.

dont forget if you do get a 200mhz fsb and you do the pencil trick you will void the warranty. certainly sucks to buy something retail and blow that lengthy 3 year warranty
