Has anyone test it a chip with blister to reball, and put it back on the board??Comment

Re: Blister on Geforce 8800 GS CHIP ?
How did it get blistered?
If it was popcorned due to reflow/reball attempt you can safely say its deadComment

Re: Blister on Geforce 8800 GS CHIP ?
No, don't see it but if that is conductive silver paste then clean it off around those tiny SMD parts.Comment

Re: Blister on Geforce 8800 GS CHIP ?
Measure across the SMD capacitors on the top of the chip. If any of those read <2 ohms (short) then the chip is dead. This is only valid with dedicated GPUs btw, things like northbridges sometimes have unused sections shorted out on the board, but if you measure the chip after you lift it from the board, it is no longer shorted.
I have had several blistered chips that still worked. But most of them do not.A working TV? How boring!Originally posted by PeteS in CAComment

Re: Blister on Geforce 8800 GS CHIP ?
I have not seen thermal paste which is conductive electrically. The surroundings looks like the chip has been reflowed, so probably it has died once again...Comment

Is a G92-700-A2 changeable (aquivalent) with a G92-150-A2 or G92-720-A2?Comment
-
Re: Blister on Geforce 8800 GS CHIP ?
Both should work. I haven't done many G92 swaps myself but i've done plenty of G86. Even upgrading the G86-703-A2 (8400M G, 8 SP) to G86-731-A2 (8400M GS, 16 SP), or replacing G86-630-A2 with the older G86-620-A2 because that's what i had on hand. All of them worked. Also in the case of the 8400M G -> 8400M GS upgrade, the driver actually picked up the extra shaders and made the laptop faster.Last edited by Th3_uN1Qu3; 05-11-2015, 06:10 PM.A working TV?

Re: Blister on Geforce 8800 GS CHIP ?
You need to replace the GPU. If i'm not mistaken, that series of Imacs is known for running very hot.A working TV? How boring!Originally posted by PeteS in CAComment

Re: Blister on Geforce 8800 GS CHIP ?
Hi,
Normally I'm not one for buying chips off eBay. But having order 10+ G86-631-A2 with a date code of 2013+ from them, they are the genuine date chip. I've never had a duff one yet.
Delivery was about 1-2weeks

This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
Common SPI bios chip programming Questions and Answers
----------------------------------------------------------
Q: I have a bios request,i can`t post my backup as i can`t read from the chip.
A: If you can`t read from it how do you expect to write to it ?.
Q: Why is my bios chip unreadable ?.
A: The programmer is faulty or has a worn or broken zif socket.
The USB cable is frayed,connector pins worn or some other physical damage.
Not enough amperage or voltage to power the programmer properly.

Long story short:
- dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
- gave the computer to his son a couple years later
- son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
- too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
(seems like the story was not that short)
He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8... -
Hello, anyone here have updated ezp2023+ chip database in .dat file format.

Thanks for any help. The board version is DAZAARMB6E0 REV: E. The bios chip is winbond 25Q64JVSIQ1736. W25Q64JV is not available in AsProgrammer -- only BV CV FV or FW_1.8c. The chip won't interface with asProgrammer and a CH341A. When I have this chip on the board, the laptop will not post but when I plug it in to power, the blue LED lights up, also the orange when the battery is connected. When I push the power on button, keyboard backlight turns on and the fan starts briefely then turns off. But I can't do anything to program this bios chip so I bought another one.
