The Truth About X clamp mods/ repairguides

What is an " X Clamp Mod" and does it work?

First the X clamp mod kit / guide ,
Are all variations on a theme ,which are to
Remove the X clamp , replace with screws and washer
to force the G.P.U. down to the board and then intentionally
over heat the G.P.U. only.

This will probably get your box working . But the P.C. board
is under stress and starting to warp away form the G.P.U.
After some time, heating/cooling cycles the connections
under the G.P.U. will fail again and now that the P.C. board
has a permanent warp in it and will prove difficult to straighten.

E 74

e74 or rrod error means that there is an hardware issue.
What you need to do is a very simple and cheap repair.
look on ebay for x clamp repair kits, these are just a few bucks and most sellers include a good guide in how to do the mod/fix.
what causes the rrod or e74 error is the X shape clamp on the underside or the mother board bending and mis-shaping causing the ball soldering on the gpu/cpu slightly melting and forming hairline cracks in the solder.
The x-clamp kit will apply more pressure to the gpu/cpu and a little trick of disconnecting the fans and turning on the xbox and allowing it to overheat will re melt the solder ball joints to fill the hairline cracks.
Depending on which chip is the issue you may also need a 2000 watt heat gun instead of using the over heating method (the gpu chip).
Replacing the heat pads on the heat sink with thermal paste which comes with the kit will keep the gpu/cpu cooler and you wont have this issue again.
Please make sure you buy the kit which comes with heat treated nylon washers as the steel spring washes fail!.
The repair takes around 1-2 hours
I hope this helps in fixing you xbox.

360 hasn been played an shuts off after 5 min of play with two

The cpu and gpu quickly gets hot if you have faulty fans and or the heatsink pads have disintrigated,
Try using a vaccum cleaner to remove any dust from the vents.
Listen and check for fans running and lastly you may need to do the x clamp repair mod.

If fans are running and all vents are clean and your warranty has expired on the console (check with microsoft), then go to ebay and look for x clamp repair kit and purchase the kit it should come with steel washers, heat treated nylon washers, screws and thermal paste. Make sure the seller also includes a guide on how to do the repair. These mods are pretty cheap BUT INVOLVES OPENING YOUR CONSOLE SO BE CAREFUL AND WILL VOID ANY WARRANTY.

You are having hardware failure. Try opening the unot and performing the X-Clamp mod to the GPU and CPU.. Depending on the severity of the problem you may need to reflow the board before performing the X-clamp mod.
