i have this Zotac 2080Ti 11GB which shows completelly bad memory D0 and D1. Lines of artefacts on screen. I change IC to new, but it shows the same error. There must be something bad on that channel. i try to measure resistances and voltages, but no luck. Card have not good cooler so maybe ball under GPU

Re: Zotac RTX2080Ti 11g - bad memory channel, after change still the same
Sounds like a bad memory controller in the core. Unfortunately I am afraid you will either have to scrap the card or change the core. -

what to check? i dont want to reball gpu just for funAttached FilesComment

Anyone run memory speed tests with an old X58-based triple channel 1st gen or any other >2 channel board? The one I have is a Gigabyte I think.
Anyway I had four 4GB DDR3-1333 modules in the 6 memory slots and got around 11GB/sec memory speeds assuming that it went dual channel since it didn't have enough modules for triple channel. Now I stuck in two more 4GB modules, but they are DDR3-1600. I'm still getting 11GB/sec speeds according to memtest86...
Just wondering, anyone do memory speed analysis on these triple (and higher) channel memory boards? Are there any... -
Hi friends
I have reverse engineered this tester, schematic is attached and is complete except for capacitor values. These testers annoyingly have no model number but they are the ones you find on the first page of just about any website if you type in "18650 4-channel tester". There is also a 2-channel variant and a newer 8-channel variant. They are very cheap (about £15) and can measure voltage, current, internal resistance and capacity. They have a multicolour display for all these statistics. They also have terminal blocks so that if you want to use a breakout board... -
Hi guys I have a VLP1500 amplifier here - one channels works fine and the other channel distorts even at low volume settings
Protection and Clip LED are off
There is something wrong with the BIAS voltages around T16 and T18 (in particular) on the bad channel
I tested all diodes and transistors in this area in circuit with diode mode - both channels seem identical. Same in resistance mode across all the resistors here.
The output DC voltages on pin1 and pin8 of the 5532D dual op amp at the input of each amplifier module are the same, and the audio... -
Hi Guys
I have a customer who has two Hitachi TVs in his bar, one is the model in the thread title and the other is a larger screen but has the same setup menu
He also has an LG TV, so three screens in the bar
I installed three Satlink ST-6503 DVB-T Modulators
This model https://www.aliexpress.com/item/32916553905.html
These connect to three satellite receivers via HDMI cables and then connect to a 4 way RF Amp that connects to the TVs on aerial cable. There is no incoming terrestrial antenna. I set the channel ID on the modulators to... -
Hi guys,
I need a help with my Marantz pm6005. It started to have weaker the right channel a few months ago, than it got back to normal and now it has lost sound completely on the right channel. At the final stage it was loosing the channel for a while and than it returned. After it has disappeared completely I could forced it back by unplugging the source form CD (which I normally use) to phone and back. It would then work for a few minutes and died again. Now it is possible power up and all function works normally (apart the right channel ) on all inputs, except the phone both channel...01-30-2023, 12:11 PM
