偶的7720 也是 3200 进不去 windows。把旧的 2400 也一起装下去就能用了。 iieeann 发表于 2021-2-5 17:09
问题是在 3200。其实找多一条 2400 或者 2666 32gb 来把 3200 的频率拉下来就行了。

是啊,但是找不到其他单条32G的,所以干脆退了,重新买2666的,省心了。我在想,是不是3200都这样。 我a 发表于 2021-2-4 17:41
换成三星 2666,32G*2,完美支持,BIOS显示频率2667
恭喜,可以安心等ddr5了,以及雷电4和USB4
我那个旧电脑是我换17寸之后打算给老妈当上网本用了,感觉chrome再吃内存64G上网也够了 and250 发表于 2021-2-9 07:24

哈哈,非常感谢~~~
我最近也打算换,网上搜了下,是说低CAS延迟的内存支持不好
There are a number of reports of difficulties figuring out compatible RAM (regardless of SODIMM capacity) for the Dell XPS 15 9550 (as well as 9570). The pattern that seems to emerge is that these systems don't like RAM with low CAS Latency. The odds of being compatible seems to increase with at least a certain minimum CAS Latency (CL) timing for a given speed. The following is likely ok with the 9550:
2133 MHz - CL 15 or greater
2400 MHz - CL 17 or greater
2666 MHz - CL 19 or greater
