Smile Cas Latency & Timing

I have 2x4gb DDR3 GSkill Ares Ram and I want to upgrade to 16gb total. I found my RAM I previously bought and noticed another almost identical set for the same price. I went and compared these two and the only difference was in the CAS Latency and Timing. They look like this:

Current RAM:
CAS Latency- 9
Timing- 9-9-9

Other Ram:
CAS Latency- 8
Timing- 8-8-8

I know the 8 means faster Latency and Timing (which is better), but I don't know if adding the faster Latency RAM with my current RAM will make a performance difference. Any thoughts?

Performance no. Instability possibly.

Mixing memory can be a real hit or miss. The newer memory may run at the slower speeds and give you no trouble.. but its a crapshoot.

Go to your BIOS, unlink the ram and change the timings from 8 to 9 on the faster ram (so yes, basically you're down clocking your ram), this should help for stability issues

run everything the same buy manually setting it in the bios. I would definitely try to run everything at the faster setting before dropping it down. Memtest on a small crappy usb stick to test before destroying your windows install.

running this over night will be enough.
