RGH another fix for slim erratic boot times

Hi to all
Just like to share my findings with everyone. After doing a couple of slims and phats I finally came across two stubborn slims - a 4GB dating may 2011 (lets call it s1) and a 250GB dating august 2010 (lets call it s2).
- s1 took something from 4 to 9 coolrunner cycles to boot and sometimes it didn't boot at all (average was 7 cycles)
- s2 took 1 cycle (instant boot) to no boot at all (average was 5 cycles)

I tweaked the wire length and shape (coil, S shape, etc), tried changing the switch from slim to phat, flashed coolrunner with xecuter xsvf and maximus. No progress were to be seen and cutting down the blue wire was just making things worse. Then I read in this forum someone stating that he coiled the wire around the x-clamp (big kudos to you). I tried it and for both console the result is astonishingly good:

xecuter xsvf, switch in slim mode and original size for supplied xecuter blue wire:

- s1 takes 1 cycle to 6 cycles (average 2 cycles).
- s2 takes 1 cycle to 5 cycles (average 3 cycles).
both glitched ALWAYS!

I didn't take a photo of any of them but I leave you guys with a sketch of the wiring below (attention - photoshop skillz level 300 :D)



notes: coils are marked red. keep your wires away from them as much as you can!
- first of all, route the yellow wire as far as you can from the coil like the drawing suggests
- as for the blue wire, and since I used original size, I couldn't wrap around 2 times, so I passed it below the x-clamp as the image is showing and the used the alternative hole to guide it to the upper side of the board. The drawing shows the blue lines quite far apart for illustration purposes - please tighten them up around the x-clamp as this will also avoid the coils near by.

Hope this helps everyone and once again kudos to the guy who tried it first and shared a hint in one of the coolrunner threads.

Hope to read your experiences with this method.

peace

very nice, will try this at home if I run into any problems with my slim tonight.

edit: looks like you fed the blue wire through a different hole that normal (I thought the yellow + blue went through the same hole?)

that is correct. the alternative hole is right next to the chip (southbridge i guess??) near the suggested coolrunner pcb placement

another success using this method. this slim is amazing: 5 out of 6 boots are near instant. no more than two cycles to be seen in this one.

any1 had success using this method or am I only lucky one?

I tried this on a slim that was booting slow for me, sadly it didn't make any difference. I ended up having the best boot times with a coiled up wire and the switch on phat on that one.

Mine booted about 10 times last night (doing installs etc) and all were less than 10 seconds using this method (with full wire length).

I just used the trinity.xsvf as well

how this for odd, I have tried your method above, boots in around 10 seconds most of the time, tested outside of metal chasis, as soon as I put in back in chasis and try again it glitches but immediatley get a red light, and no output to screen.

Nothing is touching / shorting etc, blue cable is also intact........for the life of me I have no idea, I then went back to original placement of the blue wire and it works perfectly in and out of case!

Just because it worked on one console doesn't mean it will work on all of them. It still might work for some but each console will be different from the others.

I would never figure out Slims, I just packed one back in the box and it glitches on both Phat/Slim position and even more odd it glitches faster when the switch is set to Phat instead of Slim.

I am working on a slim now, have tried the wiring as shown in pic but sadly still taking anything from 25secs - 1min to not botting at all :(

I am about to try some other wirings and I'll post back.

Edit

I now have it booting from 10secs to 30secs which is better.

Does it make a difference to boot times where the cpu_rst is? I have had to solder it to the alt location under the heatsink as I lifted the pad like an idiot!

tried this on a slim today. first had the coil at 50cm which gave slow glitch times and eratic also occasionaly quit glitching on the CR. snaked the 50cm wire, same as coiled. wrapped it as per the op's method, same slow glitches maybe less eratic though. trimmed 1 cm from the cpu rst making it 49cm, coiled it, same slow glitch. snaked it again, same slow. wrapped it on the xclamps, 5-10 second boots 9 out of 10 times and one 30 second boot, 0 fails. :) nice find mate, may not work on every onsole but definatly worth a try. thats got to be worth some rep :)
