Asus GTX 1050 TI phoenix issues

[Devin Tremper]

Hello everyone, i have been working with 3 different 1050 TI that i bought off eBay cheap for repair practice. all 3 now have the same issue and i can't seem to pinpoint the issue. 2 of the cards (one being the phoenix and the other being an evga ssc 1050 ti) would take forever to post, would then get my monitor backlight to come on but that was it. went to reddit to see what people thought and everyone kinda said Vram issues. so i went a replaced all 4 Vram chips and same problem. and I'm new to repair so i hadn't checked for shorts on the board. and there is a short on the top right VRM on the front of the card (the circled thing in the pic) would anyone have an idea on where i could go from here to hunt down what is shorted?



(sorry for poor picture quality)

Hi buddy! According to the picture you took and the area you circled, that is the power supply coil for vram. Did you measure it to see if the internal resistance is below 30 ohms? If it is shorted to 0 ohms, the entire ram set is likely shortened. You did not specify whether the ram you replaced was new or taken from another card! If you want to be clear, you should remove all the vram and measure again.

Thanks for the reply, sorry for not being specific but the Vram that i replaced were new chips i bought of aliexpress (only place i was able to find the right ones) and i did the resistance test and it is shorted 0ohm to ground. ill pull the chips maybe 1 by 1 and see which or if all are the issue. if i remove all the chips and its still 0 ohm what should my next step be? and if the issue was just shorted beads of solder ill reball the chips and try again or replace the chips if the chips are bad.

If you have stripped all the vram and the impedance is 0 ohm, it's best to throw it away because your gpu has a problem. Normally, if the gpu is healthy, remove the ram and it should be above 100 ohm. After installing the entire vram, the internal resistance drops to 40-48 ohm, which proves that the communication part to the ram is quite strong. If it's from 20 to 35 ohm, it's still acceptable. Usually, an aging gpu will have such internal resistance. For DDR5 only, DDR6 is not certain because it hasn't happened much.
