Re: Strange SDRAM DIMM
The notches aren't wrong. - It's unbuffered.
.
So you are suggesting it's 'unbuffered-registered' RAM?

Re: Strange SDRAM DIMM
Huh... Schrodinger's RAM. Registered = buffered, so it's both buffered and unbuffered at the same time, until you turn it over or look closely at the keying...So you are suggesting it's 'unbuffered-registered' RAM?Comment

Re: Strange SDRAM DIMM
And that's exactly what I was making a jab at. I figured you were aware of the distinction, but U-235 apparently isn't.Yet after I showed the key is for Unbuffered U-235 still thinks it's Registered.Comment

Re: Strange SDRAM DIMM
I wasn't sure.
I never heard of Schrodinger's RAM.

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"... -
After my ASUS motherboard had random freezes and lockups, i found out that a defective dimm caused the issue, but after change the red indication led on the board keeps flashin with new dimm memory . Reset of the pushbuttion or reset of the cmos does nothing. After the damage one FET near the dimm gets very hot and also some smoke appeared of probably small smd resistors or ic probably. After replacement the FET still takes to much power and burns. When the regulator/ power ic close to the dimms UP1642P is removed the fet keeps cool so I decided to order this and replace it with a new one. But...10-18-2025, 05:51 AM -
I have here a Magnum IA.100 which belongs to my parents.
The unit powers on & when the relay kicks in, you get a pop from the speakers (this might sound weird but is usual behavior for this amp). However, you get nothing coming through it from any of the inputs & no pops and crackls from any of the controls.
Because of the sound from the speaker when the amp turns on I have assumed that the output section probably works but I could be wrong & I'm not sure how to test that side of things further.

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... -
