Hello all. First post here and it's about our favorite Tbred. I currently have a Tbred 2100 and I want to overclock the living bejesus out of it. I know connecting the last L3 opens all multpliers 12.5 and below. My question though, is how do you get the higher multipliers? Or am I totally off base in thinking there are higher multipliers besides 13.5?

Welcome to the forums! I think the goal is to have a LOW multiplyer setting and a high FSB setting. My multiplyer is at 11.5 and I don't think you can do anything past 13.5, I think I've seen some 14s and 15s, but low multiplyers are good and high fsb is good.

Much appreciated. The reason why I ask is b/c I want to see if I can determine the highest frequency my CPU will operate at. And then, I'd use a lower multiplier with higher FSB to achieve that maximum speed.

As for method of overclocking, should I max out my FSB at the default multiplier and then drop the multiplier? Or should I max out the FSB, increase the Vcore and THEN drop the multiplier? When the multiplier is lowerd, should I also lower the Vcore? Any help would be much appreciated.

I'm not sure where multi's are at nowadays, but I'll give you my procedure on dialing in a chip:

I start off making sure the unlock is good by setting fsb low and checking all the multis; then I up the multi with 100mhz fsb and see how high it can go stable- use some fsb if you run out of multipliers.
Step two: drop to a low multi and increase fsb until it won't boot- then back off until its stable.
Now you know two things: how fast the chip can go, and how high you can jack the bus speed. Find the best compromise. leaning towards as high a bus as possible.

I start off with voltages and memory timing at defaults, then once the oc is set I'll start tweaking voltage and ram for a bit more.

Gotta bench at every setting at this point to really know for sure what settings will get the best results so it takes a long time- I put a week or two into really doing it right with a new system.

And when I have everything figured out I do a clean os install, since by now it should be pretty trashed

So when you're testing the multipliers at 100MHz and when maxing out the FSB, you're not adjusting voltage at all? You only start playing with voltage when you begin the actual process of overclocking? Or are you adjusting it as necessary at all times?

Well, you dont want to change everything at once. mess with the multiplyers first. see what you cant do without messing with fsb. If you want a high multiplyer setting then bump it up alittle everytime. If it becomes unstable, then put it back at the last stable setting. If you want low multiplyers, which is good, set it pretty low. go to FSB and start bumping that up slowly. Do everything in baby steps. I cant tell you about volt mods, becuase I dont know about them, but what i understand, you MIGHT get a few more mhz out of your system if you bump up ur volt. Main key is baby steps.

I don't touch voltage or ram until I have ramped both multi and fsb up separately to their max.

That way I have a real good starting point to work from.
Then I start the fine tweaking to get every last bit out of the system- memory first, followed by upping voltages as needed.
