E74 On a Demo Kit
Today I was offered a demo kit for $800 (hopefully can lower that price...), but it has E74, and what I need to know is, is if E74 on a dev is easy to fix, or if it would probably vary if you don't have the kit in front of you to take a look.
I would probably be able to take a guess if I had knowledge about E74 on a retail 360, but unfortunately, I myself have never gotten the E74, so I know little about it - which brings me to my next question.
Having little knowledge on how to repair E74 on a retail Xbox 360, would it be recommended to just go ahead and take a shot at repairing it, or just try to find a different dev that isn't RRoD.
Thanks in advanced,
E74 is a video error.
It is either a bad video cable (easy fix) or a bad encoder chip (HANA/ANA). It is also possible that the GPU is causing the error, but not as likely.
At $800 it's nowhere near worth your time. Not when you can easily find working kits for $1000.
That's what I was saying, which is why I want to try to to see if I can get it cheaper. If not, I'll keep looking.
For now, I'll rule the GPU out, but how easy are the encoder chips to replace?
Someone mentioned at xboxhacker.net that E74 happens when the fast "on die" RAM in the GPU cannot be initialized properly. Even thought the GPU is running (you get video) the kernel won't continue booting the system.
I believe bad solder joints under the GPU might be the cause of your problem.
E74 is neither a bad encoder nor a bad video cable. It's as serious as the usuall RROD errors (010x memory init errors), just that it happens later. I've seen consoles toggling between RROD and E-74.
Seriously, don't buy that kit, unless you want to do a RROD repair.
That's what I thought, but hoped it wouldn't be so :/
Thanks for the advice.
Now, to find a demo in my budget range.
