F**ked up Jasper / fans are a little crazy too

[Oggy]

Bought this xbox from someone knowing the boot times were a little erratic in the hope of developing a better knowledge of issues surrounding peoples poor glitch times ....

I've tried numerous wiring methods over the last few weeks, also added caps and resistors, using shielded wire, grounded the shielding ....

No pics of soldering but its captured somewhat in the video.

This is pretty much the best it's been

Not really sure where to proceed next. 50ohm made no difference.

Also, anyone have any idea why the fans get so fcuking insane come 4m30 (It wasn't hot at all) as most would have found, phats seem to ramp up the fan speed every failed reset.

I've had a bad image cos my fans to rev up crazy, wrote back the original nand and was silent, i then used multi builder and built a new image and it was quite

Quite what ?

 

[Teajunkie]

Oggy sounds odd but how does it boot if you stand it on it's side?

 

[nofeloniesyet]

Quite what ?

the fans were quite mental?

 

[GSIBOY]

Typo, was quiet what did you use to create the image

I actually tried it on previous wiring setups but not this one so I'll try shortly

Oddly, when I done my first key retrievals, I had to hold the mobo on it's side to get it to glitch as having it flat on the floor wouldnt work.

I have had the same.
Dont know why but on it's side i had a falcon that would boot in 10 seconds and under yet on it's bottom it wouldnt boot at all.

Tried different wiring positions and different cables etc.

As far as the fan speed goes have you tried pulling off the heat sinks and changing the thermal paste?

 

[Oggy]

On it's side is just as inconsistent.

Had the same issue with two Jaspers. The first glitched it's life out, did not boot even on stock after it.
The second jasper got re-wired and a new image was written to it, still works perfectly.

I have no idea what and why caused it, but pretty annoying.

Used J-Runner, 360 Multi-Builder and also Xebuild directly.

No, because it ramps up to that speed after extensive 'failed' resets.

Yeah, no sh*t. I've rewired this a few times, new cables sets, shielded cable.... Grounded shielding.

I tried 47nf & 470pf on cpu_rst (like in xb0xgurus original rewiring for jasper fixes) - 10 / 20ohms on cpu_rst. Now 4 CoolRunners.

I wish I could know it's boot times on rgh2, if only for comparison - before updating

If you leave the fans that way there is no air movement on the heat sinks it's going to start overheating, you need to have the shroud on there to get some air movement

 

[Oggy]

It does the same fully assembled...

It ramps up every failed reset, like I said.

That's what I was thinking as well. The fans aren't doing anything without the shroud. Remember they pull air over the heatsinks, they don't blow air on them. By 3-4 mins you are overheating and the console is throwing the fans into high speed.

In your video it's overheating which may be why it starts booting more often, try a reflow on the GPU and CPU and replace the thermal paste

 

[Oggy]

I guess you both ignored that I said that it wasn't hot at all after 4.5 mins.

Its not overheating. It done it for the guy when he first got it too.

If the fans do nothing, why is it not 2rrod? I'm sure with fans disconnected it would.....

Sure assembled provides better airflow, that doesn't mean that this isn't sufficient for testing glitch times.

All that aside no one has offered a reason why its either first pulse or never.

This is random it is not temperature relative to success

Ok, this is a crazy idea... but it's an idea.

How are the pins in the USB ports? The reason I ask is because my own Jasper sometimes doesn't like to boot if I've left the controller plugged in to charge and is literally doing exactly the same as what you describe and show in the video. If I unplug the controller, turn the console off and back on, it then boots firs glitch.

So yeah... like I said, crazy idea but I'm wondering if there could be a problem on the USB ports, or something is pulling too much power...

 

[Oggy]

I'll check when home, although shorted pins in USB usually stop it powering at all.

Thanks

Yeah, they do... I'm just wondering if there's a connection issue that might make the 360 think there's something plugged in... if that makes any sense at all.
