overclocking tbird 1.4

[Rob Powell]

okay I'm so sorry for being so lame but I've spent about 2 hours searching for what I want and couldn't find anything on the site or forum....

okay so I am looking to start playing with overclocking, but not sure where to start. I know I need better cooling first, not a problem. But...


are there any tutorials on how to:
Do the bridges for a 1.4 t-bird
Explain about changing voltages
exactly what else I need to do to overclock

any help would be really appreciated :)

First of all WELCOME TO THE FORUMS

If you have the 266FSB version its already unlocked so u don't have to mess w/ the L1s. You can check the first line on ur core that starts w/ A1400.. if it last char is 'C' then u have the 266FSB of its 'B' u have a 200FSB. You should read the begginers guide on the front page to get started and if/when u have questions just ask.

Make a sig w/ ur hardware like mine or something like that.

wow a quick service, thankyou :)

I will do that and come back with questions I am sure :)

Basic spec for now (Im' at work so dont' have all the details)

Rig setup:
CPU: AMD T-Bird 1.4Ghz 266FSB
Cooler: TBA (needs upgrading)
Temps: 49C° @ idle with side of case off (Crashes with case side on)
MotherBoard: Epox 8K7A
Video card: ATI Radeon 64Mb VIVO DDR
Memory: 1x512Mb DDR Crucial w/ECC

okay just a couple of Q's for starters....

1. My system is running hot with my current (very poor standard) heat sink and fan. Are there any good products below £20-25 that would increase cooling without sounding like a 767 is taking off? (uk only)
2. I have the epox 8k7a. Do I just increase the FSB or the multiplier, or both?
3. If I increase the FSB speed, do I need to adjust my pci bus speed so my DDR ram still runs at 133? or is it best to overclock that also?
4. I hear the 133FSB doesn't get as good a result as the 100, what should I expect to get out of my 1.4Gig?
5. if my 133/266 chip is already unlocked, just to double check, what basically are the things I will change? The jumpers on the mobo with the FSB settings in the bios?
6. Where on earth does voltage come into it? I didn't see that in any of the guides

edit: 7. what is folding?

Take a look at the sig and this is a 1.4 t-bird with h20.:)

1. Have u got any case fans? Adding case fans, and increasing the air flow through your case can help. YSTech sell some high rpm fans which are reasonably quite you could try on top of your heat sink, about £15/20.

2. I'd start with your FSb first, as it is the easier of the 2 to change on your board. If you run Seti (http://setiathome.ssl.berkeley.edu/) or folding (http://folding.stanford.edu/download.html) then a higher FSb will help.

3. When you increase your FSB on that motherboard it increases your PCI and DDR anyway, no way off getting around that.

4. I've not heard any difference between the 133 and 100 chips, your should be about to get 1.5/1.6 from that chip on air cooling only.

5. Yes the FSb is in the bios and the multi is a jumper on the board.

6. Increasing the voltage to your chip and your memory can help to get a more stable overclock. The downside is increasing your voltage will increase the heat aswell.

7. see the links in 2.

Welcome to the Forums.

Good luck with your overclock. :D

Firstly, all the 266 chips over 1.2ghz are unlocked, the 200 chips are locked.

An increased FSB will give better memory benchmarks, this will help in memory intensive apps. Increasing the multiplyier makes the core of the chip go faster, this will give you better results in cpu intensive apps.

FSB, mutliplier and the Voltage are the main things to play with. You can also change the memory settings (cas, etc) aswell. The most important thing to keep an eye on is your tempatures.

The mix of multi and FSB is down to your and what your system can do. You might geta higher overclock using a higher mutli than FSB, if you have PCI/AGP cards that can not handle a high FSB.

Aim for 1.7, I got my 1.4@1.64 stable, with a 11 multi, thats on air. There have been a few people to get above 1.7 on air, but not many. If you get to 1.8 then well done to you. :)

Try different multi's and see what works best, go up one stage a time, test the overclock each stage (Use something like, prime95, seti, folding. sandra) check that your temps don't go to high.

A rough temp to stay under would be 50c.

Increase your voltage a little at a time and see if it helps to make the overclock stable.

Also updating your BIOS may help.

temp is 51.5 BEFORE overclocking LMFAO

okay, before i play with anything, I need to get a good heatsink and fan. Currently? Forget current, cheap and nasty.

from cclcomputers:

Global Win WBK38 High Performance Cooler £21.68
Global Win CAK38 Copper Heatsink & Fan £36.87

either of those good value or good sets? Or what would you reccommend from YSTech? I hear copper is best... okay I've upped my limit to £30 if it includes delivery LOL

[RED Hot Machine]

I've got a Glaciator II, they are about £39.98 pounds (shipping,vat incl), and it is nice and quite. (Got it from www.overclock.co.uk)

Take a look at the review on the front page, they have a list of the top hsf combos, how they compare and how noisey they are.

Both of those get good reviews.

Oh yeh, I did'nt mention that mine is a 266.
