I have a low battery flag on the post test coming up. I already ordered the chips they have the battery built inside them. I got new chips and n ew sockets. question is, what chip reader to get the memory from the old and write to the new? the new sram is maxim ds1230ab, someone out there has been thru this before and I would like to keep this old scope working. its like a family member had it since it was new.

Re: help with 2430a tek scope
The mcumall GQ-4X that I have would read that.
Not saying I recommend that programmer specifically though.
There are probably many that can read such a Dallas chip..."The one who says it cannot be done should never interrupt the one who is doing it." -
Re: help with 2430a tek scope
thanks, I have looked at it and also the new 866-II. the reason I lean toward the 866 is it is totally usb and also has windows 10 software. my old win 7 laptop died last week and either one or the other will be here soon.Comment

i have seen arduino's used to read/write those rams.Comment

Re: help with 2430a tek scope
ok, I got it running and passing all self tests now. I have dallas 1230ab's in it now 2015 date code. I have been told that fram will also work so I socketed the ram, saved the files and will try it once the chips get here. I wasn't the easiest thing I ever tackled but it isn't real bad either as long as you do one at a time.Comment

I'm looking to upgrade several 8GB 820-00850 boards to 16GB or 32GB for personal use. I am curious what the best practice and process is for sourcing new replacement chips, and what vendor(s) you guys prefer? Another question is, how do I find compatible chips and their corresponding part/model numbers? For example, in the 820-00850 schematic, the DDR chip U2600 model listed (EDFB232A1MA) corresponds to 1x32GB chip. Of course, I would need 4x8GB chips to replace the 4x2GB chips currently on the board. How do I find compatible 8GB chips? Is it as simple as searching "BGA178 8GB 2133"... -
Hi,
I asking for help on some new WSON8 256MB chips. Please share your experience. I faced error on some new chips on read, erase, write with different programmers. These new chips are not exist in any programmers database. (GD25B256D, XM25RH256, W25Q256JV so on.)
I'm using RT809F V.5.0, EZP2023 Pro, CH341A Green
For the exact experience with GD25B256DYIG is RT809F erase the chip under 33sec. This kind of 256MB chip normal erase time is 70-120sec so I think not all the partitions are erased. If I do blank check or reread the buffer says FFFFFF but when I write the correct... -
Hello dear badcappers!
The title pretty much says it all - do you, please, know if there's any way to troubleshoot which of the integrated RAM chips (LPDDR5X in this case) is faulty?
Backstory:
After replacing the 4 onboard (soldered) memory chips on a RoG Ally (4x4 GB to 4x8 GB) it got stuck on the RoG logo. I assume one of the chips is either not soldered properly or faulty. However after reflowing and replacing bunch of them I am still stuck at the same place.
If there is a way to narrow down which memory module is faulty it would make my life much... -
Hello again! (People are likely going to get tired of seeing posts from me lol)
I'd like to try and compile a list of known bad AMD/ATI Chipsets and graphics processors.
While I do not possess the knowledge of some of the brilliant minds on this forum, I can at least mention a few chips I've encountered as being troublesome.
1. ATI 216-0752001 (RS880M/RX280M) found inside 2 HP laptops, one I've since deemed screwed, and swapped the board to an intel one, the other HP seems to be less hateful and runs fine.
2. ATI Mobility Radeon X1600 and the... -
Just archiving everything related to bumpgate since most stuff has disappeared from Google. Maybe people will finally take the time to read some of it and stop shouting "reflow gpu" at every occasion but rather try to understand what the real issue is…
Interesting parts about the failure analysis are "Why Nvidia's chips are defective" and "Why Nvidia's duff chips are due to shoddy engineering"
May complete this post at a later date with more details.
Basically issue is a combination of thermal dissipation of the chip with hotspot,...
