T-Bird 1.4GHz OC

[tao52]

Since most mobo's have 12.5 as the highest multipier setting, and since i have a 1.4 Ghz t-brid rated for 266 mhz fsb with a former factory locked multipier at 10.5, and you can also buy for like $30 on pricewatch.com you can get a 1.4 tbird for the 100 mhz fsb which means it has a multiplier at 14x and if you run it at 133FSB then its already overclocked to 1862(14 x 133) then you can up the FSB even more, any idea what voltage settings it would need to run, and this would be done on a Gigabyte GA-7VTXH+ with a water cooled tower from Koolance.com.

First the Thunderbird 1.4 266s are factory unlocked whereas the 200s are not. This is true as far as I know. Secondly you most probably will not be able to achieve that 14 x 133 you state in your post. Sorry but FSB overclocking will overclock the whole system meaning that your whole system will be faster and as such is a better overclock rather than just upping the multiplier.

Edit: I almost forgot, Welcome to the forums:D

I once thought that also, not all chips will do 14x133. I beleive the 200mhz FSB chips do better than the 266 IMHO. Prepare for about 2.2 v-core to acheive those speeds.

I think i will stick with my 1.4 ghz (10.5x133) and see how fast it will go. I look forward to my first real OC experience

Get some good cooling and up the voltage. She will do a good 1.7.

I think you got it backwards. all I can say is mine is factory locked.
I have had some one wanting me to take pic of it but that is a lot of trouble to prove a point. don't see why the 200's past 1.2 would even come locked because in a board that is disgned to run them 13 is the highest ajustable multiplier. I notice in your sig you are using a 1.4. I would think you would know if it was locked or not so some must be and some not.

This is getting interesting. I have a KA266 with the latest bios flash and it has a 14.0 multiplier. As luck would have it I just ordered a 1.4 200 FSB chip. I currently run a 146 FSB without any problems. We will know in about two weeks if it will do 1862 (14x133 ) stable.

WOW this is the first thing about a pc to excite me since water cooling ! LOL

If you browse the CPU Database, you'll see that those speeds probably are possible, but I think air cooling would be out as an option. Water, Water w/ a Pelt orVapochill style units might make it do-able.

Water at 2.34v gets me 1.745 which is what I am running at now. It will post at 1920 however it locks down hard. Pelt cooling should push it over 1.8. Kind of mute as the xps are going over that now.

Sorry but I think that that you are wrong. If you set the FSB to 133 than your PCI will be at 33Mhz and the AGP at 66Mhz since the 4th divider will come in.

I had my 750Mhz Duron at 1Ghz with 133 FSB and the AGP & PCI at normal speeds.

Of course I would be betting on the cooler temp requiring less voltage. This in turn would reduce heat load. The present setup is water cooled only at 2.35v.
