Hi,
I have a RTX 2070, all memory are brand new. However channel A (A1 and A0) doesn't works, there is error on all bit with MATS. Do you know if there is a specific voltage to check ? vmem is at 1.35v but I don't know how to check other "specific" voltage. I believe the issue is a non working voltage because it's only making error on channel A, traces were mint.
Thanks for your help


Привет,
У меня RTX 2070, вся память новая. Однако канал А (А1 и А0) не работает, ошибка по всем битам с MATS. Знаете ли вы, есть ли определенное напряжение для проверки? vmem составляет 1,35 В, но я не знаю, как проверить другое «конкретное» напряжение. Я считаю, что проблема в нерабочем напряжении, потому что ошибка возникает только на канале А, следы были исправны.
Спасибо за вашу помощь

Who is the manufacturer of this board? Please post images in very good quality of both sides.

It's an HP model, it have the same PCB as the 2060/2070 FE card, let alone the 8 pins power connector.
Only memory bank A0 and A1 are failling on all their bit while the memory is brand new (Samsung), this might be the IMC but I don't believe so.

Why did you bake up this GPU without a diagnosis? You may already have killed it. Why do you use so bad rosin flux? Baking a chip is a very bad idea when you don't have idea what happened.
You need to remove the GPU, remove both memories, ring traces, test GPU balls in a diode mode. A lot of work.

There is no secondary/reference voltage on GDDR6 that can make an entire channel not working ? The result was the same before reflowing the core.

I have the same exact issue on a 2070 laptop.
Mats shows errors on A0, bits A001 and A017, errors are 00000002 only.
Checked data lanes all good.
Next step I will reflow, if it doesn't work I will reball.
Testing data lanes with multimeter doesn't help most of the times.
