Dual Channel RAM Help

[JohnSmith13]

I recently bought a Thinkpad E595 that came with a SK Hynix 8GB 2666 MHz RAM stick. Because the E595 uses the integrated AMD Radeon Vega 10 GPU, I got an extra RAM stick for the increased performance from a dual channel setup in case I ever want to use the computer for some gaming. I added a Crucial 8GB 2666 MHz RAM stick that was advertised to have the same latency, voltage, etc. In CPU-Z, though (screenshots below), it looks like the timings of the two sticks are a bit different, but the computer is using the Crucial timings. While the computer seems to recognize this as a dual channel setup, the "asynch." status under FSB:DRAM and the DRAM frequency has me worried. Are there going to be any stability issues? Will there be any notable performance differences compared to, say, a matched Crucial RAM dual channel set? Thanks in advance.

are you having stability issues

is the ram performing badly

Get an up to date CPU-Z first

No and no. However, if there are any potential problems or a noticeable performance gap that might occur, I'm still within the refund window.

Re-attached screenshots with up-to-date CPU-Z below. Other than DRAM frequency, numbers are the same as before.

so it's running 1866MHz CL17, which is much worse than JEDEC speeds. does DRAM frequency go back up if you use the single 8GB stick from the factory only?

No, IIRC using the factory RAM also had a DRAM frequency of 933 MHz. I suspect this might be a quirk of the motherboard. According to another thread on the Lenovo forum, when idle, the DRAM's supposed to be 933 MHz (or 400 MHz when idle on battery power, which would account for the first set of screenshots). It's only when the system is under load that the DRAM goes up to the maximum of 1200 MHz.

then you should put load to it and see what it runs at with two sticks
