If you're getting some performance issues, I would make sure that your ram is infact stable (linpack, ycruncher, superpi, p95, testmem5) . Memory instability presents itself in strange ways. Also, before you go on your venture, just know that benefit from bringing CAS latency 30 will have nearly imperceptible impact on performance unless you are running benchmarks (from where you're at with BZ settings). For example, you probably already went from high 50's GBps read/copy to mid to high 60's GBps and dropped latency from 70's ms to low 60s or high 50 ms. It will also potentially require a voltage increase or drop in frequency. DDR5 greatly benefits from secondary and tertiary timing tuning along with frequency, followed by infinity fabric. Instead of focusing on primary timings, I would see if you can push your kit to 6200 or 6400 mt/s, if you can't get 6400 or 6200, see how much you can push IF. That being said, from reading your post, and this is not meant as as insult, it appears you are very inexperienced when I comes to RAM tuning. Unless you are serious about learning at least some aspects of memory timings and interaction, I would just stick to BZ timings and move on with your life. You can quickly go down a rabbit hole for very little gain beyond what you currently have.

Unless you're looking for something like a Strix or the Liquid Suprim from MSI, all 4090s perform virtually the same. Some will have higher power limits, but the gains aren't really worth the power/heat increase. Buy the one with the best warranty unless you're taking the cooler off to put a waterblock on it.

Didn't even know this was an issue, at least in DCS.... I guess ignorance is bliss.

Its a P3 Kill-A-Watt. Can't remember where I bought it, probably Newegg or Amazon, but it's been close to 15 years. The benchmark is a Cyberpunk built in benchmark that runs same amount of time for each run, couldn't tell you the length right now as I'm at work. Off top of my head its like 1-2 min long.

Just got the UPS hooked up and running the same Cyberpunk 2077 Overdrive benchmark it was pretty much locked at 486w output (similar to what the smart plug reported) with one momentary peak to 513W. It appears Kill-o-Watt is the outlier.

Posted for awareness and hasn't been personally tested. I'm on a 4090.

AMD released new drivers that supposed to address VR performance. https://www.amd.com/en/support/kb/release-notes/rn-rad-win-23-10-01-41-vlk-extn

I thought it was an APC-branded UPS, however, it's actually a "CyberPower 1500VA / 900Watts True Sine Wave Uninterruptible Power Supply (UPS)". It's just going to have the Synology NAS, Unifi Dream Machine SE and two switches on it. We don't typically lose power for long but recently with the weather, have had frequent quick outages and the NAS hasn't been happy about it.

I have an APS battery backup UPS coming Thursday for my server room but I'll hook it up to my PC and see what it reads. I'm not sure how accurate the sengled plug is, but the Kill-a-watt was, and from a quick Google, still is a popular measuring tool and folks report as accurate but there's no telling if it went off at some point of its 15 years of sitting in a drawer. Unfortunately until the UPS gets here I have no other way to measure, but the readings have been surprising if nothing else... Especially the disparity between the killawatt and the smart plug.

PSU is an MSI MPG A1000G, so I don't think it's the issue. I'd be more inclined to think that the 15 year old kilowatt P3 may be the issue. Unfortunately I don't have another way to measure other then in-windows reporting and napkin math. Edit: so I just thought of something and grabbed one of the smart plugs that records power use/draw I had on my 3D printer. Cyberpunk 2077 RT overdrive benchmark indicates 463-480w draw at the wall. No idea how accurate these are (sengled smart plug), but it's a heck of a spread from the killawat P3.

To be clear, the 880-917w (Cyberpunk 2077 RT Ultra) was from the wall while benching (built in benchmark). Same bench in RT Overdrive was pulling 940-947w. DCS Marianas F18 free-flight in VR was pulling 610-642w. Diablo 4 in-game, pulling 520-560w-ish. If all you're doing is DCS, you have headroom. But some things may be more demanding. I'm actually surprised CyberPunk 2077 RT overdrive pulled that much power....makes me think I should have gone with a 1200w+ PSU instead of a 1000W lol. @some1 Do you by chance have Cyberpunk 2077 and could run the built in benchmark to see if your power-draw spikes?

Just the tower and anything that's plugged into it.

917w at the wall plug on the kill-a-watt while benching. Thats with everything in the signature + EK-D5 pump, 6x140mm fans, 3X Nvme SSDs.
