Xecuter 2.6CElite - 2 XBoxes Fragging - Perfect Solder - Bad chips?

[Scalito]

Hello all, this is my first post here, glad to see people willing to help.

I recieved two Xecuter 2.6CE Lite chips. I've went through the process of installing them on two 1.6 boxes (roommate's and friends) and have read and re-read everything I can on this issue.

After checking and re-checking everything, I have no clue where I am at. The best thing I can think of is that either I got bad chips or that they didn't include Flashbios on them.

I have used a multimeter to check every connection on the LPC rebuild (one with the PCB and one with just wires, both check out fine). All wires check out great for connections, checked everything three times. With the chip disabled, both xboxes load default bios with no problems. Once enabled, they both frag. Both refuse to load Flashbios.

I have taken some pictures of both mod jobs to help show that every point is soldered correctly and have been checked by a mulitimeter to show connections are fine..

Two XBoxes - One PCB, One rebuild

Any ideas guys? I really appreciate the input

I know it seems obvious, but these are both 1.6 xbox's right? Video chip has the xbox symbol on it? (oh and should you really be working on a motherboard sitting on a towell? Try some anti static material if you can get your hands on it.)


Use your multimeter and test the voltage on each pin. I'm sure it hasn't hurt anything, but you don't need to jump pins 9 and 15 on the rebuild either. I know the pcb does, but it works fine without (nearly all the time ) and saves you some wire and 2 solder points.

Ah yeah, the 9 and 15 connection jumpers were just for the hell of it. The pcb had them, so we thought we'd try it out.

The towel is for pics by the pc

Both boxes are 1.6's - both chips have the Xbox Xyclope chip and identical layout.

I can't test the voltage as my friend with the mutlimeter took off earlier. We did however test each connection over and over for connections, and he had it set to detect so and so amount of resistance. Somethign like that, he's the one with the hardware know how

Ugh, honestly, I can't help but think they are just bad chips. We've done everything five times here, lol. I got them from Divineo.com, btw.

It would be a rare find to get 2 dead chips on one shipment. Very unlucky indeed, but there is always that possibility. If you can check the voltage rather than resistance it will tell you more. The resistance tells you if you have continuity, nothing more. (often thats enough) but, if you test voltage you can be sure.

 

[Scalito]

Yeah, very unlucky indeed. I think that possibly the chips just don't have the Flashbios on them, since they seem to operate (switch on/off at least).

I will see if I can get the multimeter back again tomarrow and do some voltage testing. Like you said, I would think that continuity would be the major thing here, but never know I guess. Any idea what a good reading would be?

Any other ideas? lol, sorry man, but this is just strange :/

They differ, refer to this picture

And some people get upset when we say this, but the vast majority of issues in frag cases is soldering problems. The next biggest reason is a bad flash, but you haven't flashed yet, so stick with the soldering problem.

Yeah, that's what i've been reading.
Thing is, i had a third year electronics student doing the work. he had good equipment, and all the lines tested out so I don't think it is a solder problem. We did quite a bit of testing and redoing the points, that is why I have one w/ PCB and one without.

I guess it could possibly be voltage, I'll be testing that out tomarrow..thanks again for the input
