MemtestCL 测试失败是否需要退回我的卡？

Question

我只是 RMA 了我的 Asus 280x DirectCU II 卡，因为它不会输出视频。

RMA 给我寄回了这张卡，它在运行 BF4 时有一些小瑕疵，所以我怀疑 GDDR5 RAM 坏了。这是测试，但我没有什么可以比较的。我不确定这些错误是否确实证明我应该退回这张卡。

MemtestCL 结果：

更新：使用较新版本的 MemtestCL 后进行测试

在https://github.com/ihaque/memtestCL（下载 zip 已经在里面编译了 .exe 不需要编译）

我确信您看到的错误是错误的。

“随机块”测试看起来有缺陷。考虑到随机块测试失败的严重程度，我预计至少其他一些测试也会失败。然而所有其他测试都出色地通过了。

如果 RMA 一张实际上完好无损的卡，那将是一种耻辱。

更新

查看此论坛帖子，该帖子与塔希提岛的随机块错误有关 - 与您的问题完全相同：

该问题似乎是 memtestCL.exe 中的错误...

Windows 版本似乎也受到影响：

我的两台 6850 在 Win7 x64 上进行的相同测试都失败了...

我不知道你正在运行什么版本的 MemtestCL，但考虑到它的维护量很少，我会在 MemtestCL 出现故障时投入大量资金，并且你的卡实际上完全没问题。
