TRINITY CR4 XL Tuning Advice

Hello Everyone.

I'd done a few CR Rev C Phat's in the past.

This is my first CR4 XL on a Slim (Trinity).


Everything went smoothly. Although it took me a while to remember all of the steps in reading / flashing the nand etc.

Anyhow, I'm getting anywhere between 1 and 10 glitches to boot.



  • Trinity QSB V3 Board
  • Nand-X
  • CR4 XL
  • Dip switch settings 3,4
  • Postbit jumpers - Default
  • Type of CPU_RST Cable Used (Default/Pro Cable/IPEX) - TX Pro Cable
  • Any QSB jumper/switch settings - No
  • Any caps installed - No
  • Any special Cb's used (Falcon CB on Zephyr etc) - No
  • Screenshots of RATER if used - No


My main question is, what is the procedure for tuning the CR4?? I've looked around the forum and googled but am not finding any good advice on how you get your best settings.

It seems like there should be a sticky for this. Something like "How to get started tuning your CR4 XL".

I'm afraid to do much because I don't want to damage anything.

Here are some specific questions:

Is there a list somewhere of how these switches work?
How to know when you find your center timing?
How to know if a cap should be used?
Do the caps have polarity?
Should I use the POSTBIT Jumper?

Please don't tell me that I am just supposed to randomly experiment with all of these things. ;)


Sorry for all of the noob questions. I'm handy with a soldering iron, etc. but I'm no electrical engineer.

That is how we learned to tune by experimenting and reading what others have done to get a fast glitching console
Most of us would use RATER for the tuning
It is almost impossible to hurt the Any TX glitch chip as long as you dont burn or pull pads on the chip
Team Xecuter found the center of the base timing already its the default setting
Try the 10 cap first see if your boot gets faster

Thanks for the quick reply stucknvegas.

I will experiment with your suggestion and some of the settings I've seen on the forum here.

Unfortunately I don't have the rater so I will only be able to do so much I suppose.

Would you say that at this point I would leave the DIPs on 3 and 4 and just experiment with the Caps?

Yes start there//// HDD installed DVD drive installed and WIFI card as well
When testing the boot times record your results manually
After the console boots let it run 30 seconds- After you shut down 120 seconds cool down retest minimum 10 times

everyone as done exactly what is says in the tut , as above try different dips and jumper setting then if you are not happy try caps , I usually get good boot times with jumper default and dips with no caps on a trinity

Thanks for replying guys but I think I found the info I was looking for.

This is for the CR3 and a Corona but it has this part about tuning that I think might be helpful. Can you guys tell me if this info is different in any way for the CR4 or for a Trinity?

1. Add a ceramic cap to C10 with 1 DIP on (note a 1 cap per DIP cannot be higher than 50pf - anything higher will absorb the pulse)



2. So start with a 10pf cap and test. Then 22pf then 30pf then 47pf
3. You should now be getting a score of > 8.5
4. Sometimes you may need to tweak even further than just 1 DIP and use a combo. So for example if you found DIP 3 and DIP 4 to be the same you can try 3.5. We achieve this be setting DIP 2 & 3 on with a large ceramic cap to delay and absorb the pulse (so 2 DIPS and a large cap equals 1.5 pulse time)
5. So to achieve 3.5 set DIPS 2 & 3 on and test with caps 68pf, 82pf and 100pf.
