Hello, I have a separate post about my CPU (7920X) But I also had questions about my ram as well. I have an ASUS X299 Stirx E motherboard with a Core i9 7920X CPU. My ram is 32GB (4) 8GB sticks of Corsair Vengance 3200Mhz RGB DDR 4 Kit. The XMP profile timings are 16-18-18-36 @ 1.35v to run at 3200 Mhz. I have been able to run my ram at 3600 Mhz using the timings of 18-19-19-38 @ 1.36v, these are the timings of Corsair's 3600 Mhz Vengance kit. Is this safe to do long term? I ran Aida 64's memory tests/benchmarks, as well as Real Bench and Mem test, everything checks out just fine, as well as just normally using my PC for a couple of 8 hour work days. Am I going to really get any real benefit doing this vs. the possible, if any, damage it may cause? Honestly I've tried it because I wanted to see if I could run 3600 Mhz ram without having to drop $250 or whatever it costs to buy it right now. Keep it mind that eventually (Maybe within a year or so) I want to upgrade to a 64 GB kit anyway and I plan on getting a 3600, if not 3800 or 4000 Mhz kit.

Cool, So I'm good for a few years or so? Eventually this ram will be moved to my wife's PC in year or so, I still would want it to work at it's rated speed. Do you think I'm going to gain any benefit from 3600 Mhz, gaming or application wise?

Safe but kinda useless, don't expect that 3600mhz to be faster than your 3200mhz config. With memory, performance is measured in latency. There are plenty of 3600mhz kits that are just as slow as 3200mhz kits. Because of timings.

However if you can get to 3600mhz with the same timings at 3200mhz, then that'll be quicker.

I haven't tried that yet, I'm going to now though. I had to bump the voltage from 1.35v to 1.36v to get it to be stable, I'll keep that on and just drop those timings down. I'll remember this when shopping for my next ram kits. If you have some time and some knowledge about it, I have a post about my 7920X if you have any thoughts about what I'm doing there, it's a voltage/longevity question. https://forums.tomshardware.com/threads/static-or-auto-adaptive-voltage-for-7920x.3509613/ Thanks for your help.

So, best answer. Tried the 3600 Mhz on the lower timings and... no go. However it works just fine with 3466 Mhz at the 3200 timings with the 1.35v too, so slight performance gain, as far as I can tell it's stable, I'm done testing for now so only time with regular usage will tell.
