How are VRAM errors on GPU servers repaired?

GPU VRAM errors fall into two kinds: correctable ECC errors (usually transient interference — logged and ignorable) and uncorrectable ECC errors (possible VRAM chip hardware faults or GPU core issues). The latter requires repair. ZhongLianDa runs a professional GPU repair team with BGA rework stations and VRAM chip stock, fixing common issues such as cold solder joints and failed memory chips. Repaired units pass a 24-hour stress test before return and carry a 3-month warranty.
