Hello, I have these G.skill 2x8gb sticks with default xmp profile 3600mhz at 1.35v 17-18-18-38 Earlier with my 7700k, I couldn't overclock these to even 3800mhz. But now since I upgraded my system with i9 10850k and Asus Z590-E, I can get the ram to 4266 mhz at 1.45v. Here are the stable clocks and voltages- 3600mhz @ 1.35v 4000mhz @ 1.40v 4266mhz @ 1.45v So, my question is, is it safe to run these sticks at 1.45v 24/7. I have run bunch of stability test including aida64, prime 95 and even real world testing in games. and haven't had a crash or bsod, yet. These sticks have Samsung B die.
Yes, Samsung B-die are fine to run 24/7 up to 1.50 V (used in some 4600 XMP kits) as long as your case has decent airflow. Can you post a screenshot of your timings at 4266 MHz with ASRock Timing Configurator? Could you also please post a screenshot of your bandwidth using AIDA64 Cache and Memory benchmark?
24/7 1.5v shouls be fine, althought i had issues with it.. I had one kit of F4-4000C15Q-32GTZR when i built my new pc. Was running default XMP on my Z490 Asus XII Formula. RAM was on both QVL Lists. Died on me after barely half a year. Performance was degrading and BSODs happened from once a month up to daily. Happened to me twice already that G.Skill Kits died on default XMP on supported Mainboards. Just a heads up.
Sorry for the late reply. I couldn't get the Asrock timing configurator to work on an ASUS motherboard but here are the results for cache and memory benchmark for both 3600mhz and 4266 mhz.
Thanks for those screenies, nice bandwidth and latency at 4266. I would really like to see your timings, can you please try Asus MemTweakit and take some screenshots of of the tabs with Timings #1 and Timings #4? I am going to try for 4266 MHz on my Z370 and 9900KS this weekend and would really appreciate the screenshots to make a comparison.
