Aw, Nuts!

Ordered a memory upgrade for my PC and it arrived Saturday. And then all my games started crashing. Sometimes to desktop, sometimes a hard reboot crash. I asked the PC maker for memory that my laptop motherboard would support, but I am wondering if that actually happened. My old RAM was 2667 MHz, new RAM is 3000 MHz. Don't know if the new RAM needs a different voltage to be stable. And I found out that my BIOS setup doesn't allow me to modify that, anyway... waiting for the company to get back with me for tech support and hoping they can either get the new RAM to work when I play me some games or get an RMA set up so I can get new RAM that will work.

Meh.

Hi Dean,
Do you have all the detail about your laptop, the old RAM and the new RAM?

RAM has timings, I'll need to look up again what they mean as it's been about 15 years since and I've forgotten. I am wondering if the faster speed RAM needs slightly relaxed timings to suit (or the new RAM needs different timings and your system is using timings for the old RAM?). You can get current timings from CPU-Z tool. The old and new RAM should state what timings are required. Here's a cpu-z showing the RAM timings

Also I forgot to ask - are you mixing DIMMs of different type? Because (you probably have figured this out if so) you'll need to suit the slower DIMM in the set in terms of speed/timings.

I got the CPU-Z to do troubleshooting, can concur it's an awesome app to have handy!

Not mixing DIMMs, both sets are two of the same, and the newer set has more clocks than the current set. I'm debating about trying to flash the BIOS with a version that allows me to set clocks, speed, and voltage... may just wait for the support to get back to me.
