Would changing ddr 6000 to 7200 would change much ?
What CPU?
If an intel CPU? Yes. You will notice more consistant FPS aka less drops in World content, Raids and Major City Hubs
7800x3d so might not be as worth
Then absolutely not. 6000mhz runs at a 1:1 latency ratio. On a 7800x3D you are capped at 6000mhz to keep 1:1. Going to 7200mhz would be 1:2 and it would tank your performance. Ram speed means very little on the x3D chips. Why? The Large L3 cache significantly reduces the need for frequent memory access. Basically it acts as a dedicated RAM buffer reducing the need for data transfers from system memory.
One of best selling points about any X3D cpu is you can enable Expo at 1:1 and you are done. If you want an Easy Time just enable Expo and set your ratio to 1:1. To do so manually in your Bios Enable Expo II, then set FCLK 2000mhz and set UCLK=MEMCLK in your bios in the Ram Timings section. Thats 1:1

FYI I was on the 7950x3D and moved to the 9950x3D. I saw next to 0 difference in wow FYI. Just slightly better 1% lows
So being on the 7800x3D yourself. CPU wise you are pretty much on the best you can get. So if you are looking for more performance only thing you could possibly do is either a GPU upgrade or MANUALLY set your ram to 1:1 in your Bios like I explained above (this can matter quite a bit even on the 7800x3D) The reason for this is that your guaranteed your bios will will never run it at 1:2

check out techspots latest article " Is DDR5-8000 Worth It? The Ryzen AM5 Test" as it reiterates much of what you have been saying
So there you have it – as expected, when CPU-limited, DDR5 memory can improve the performance of AMD’s latest generation Zen 5 processors. However, based on what we’ve seen here, Zen 5 doesn’t appear to be as memory-sensitive as previous generations of Ryzen processors.
For example, the new CL26 memory provided at most a 9% uplift over the CL30 memory used in our Zen 5 evaluations. That’s a notable improvement, but in most cases, the gains were in the 4 – 5% range. DDR5-8000 was up to 12% faster, but overall, there was very little performance difference between DDR5-6000 CL26 and DDR5-8000 CL38.
I have and keep in mind they are discussing 8000mhz in that article not 7200mhz. The main issue here is X3D CPUs vs non V-cache CPUs. They both react differently to RAM
I’ve done extensive memory test on Zen 5 CPUs. Bottom line is the X3D CPUs do not really benefit from faster memory in gaming. Workstation tasks are a whole nother conversation
There was almost no difference whatsoever in gaming on any X3D CPU I have tested. 3% at best and that was at 7800mhz. However on a CPU such as 9700x, 9900x or 9950x faster memory is definitely worth it and there was a pretty decent uplift. As much as 15% in some scenarios.
With that said you have to go over 7400mhz to overcome the drawback of the 1:2 ratio. All of this is why I stand by my original statement I made to the OP
It seems their article reflects a similar analysis
they also state " when CPU-limited" which would happen more often in their test with the 9700x as opposed to something like the 9800X3D which they also state "Many of you are probably curious about the 9800X3D, but we didn’t include that CPU in this testing – it would have added a lot more work, and we already know it’s not particularly sensitive to memory performance. This was most recently demonstrated with the 9950X3D, so DDR5 performance is more relevant to the non-3D chips."
Basically a lot of what you have been saying the past few months on the X3D side and even on non-3D the results are more marginal and dependent on being CPU limited.

You always seem to be like a great PSU expert so I got a question for you.
I took my Seasonic PSU out to clean it had it sitting on the table and my dog saw squirrel outside when charging for the door bumped table and knocked it off. Needless to say it broke 
So my question for you is since I obviously have to buy a new one. Seasonic Vertex GX1200 or Corsair RM1000x? Personally I have always used Seasonic since I have never had one fail me. However you are always such a good expert on power supplies I figured I’d ask your opinion before I pulled the trigger. Hopefully with the new one I will never be as stupid as I was with the new one 
Im guessing the Seasonic Vertex GX1200 over the Corsair RM1000x maybe a more solid option especially if I ever wind up upgrading to a 5090? However I’d like to hear your opinion nonetheless. PS> price is not really a factor they are within $10 of each other.

I assume both are the 3.1 version if not I would say go for the latest one and you already stated price is equal otherwise I would then say go for the cheaper one. Both are excellent so #1 there is no wrong choice, it’s like a Honda Accord vs Toyota camry.
Seasonic is in-house made full bridge topogoly vs the corsair designed CWT built half bridge (they use full in the 1200w) kind of an enhanced CSZ platform. Primary caps for both come from Nippon, secondary side both Nippon & Rubycon. Switches & Mosfets all come from the usual top of the line guys (Toshiba & Infenion).
Basically all the parties know what they are doing when it comes to design, parts, manufacturing process including QA & QC. warranty is 10years for both and both brands live up to their warranty in my experience. Some people may have a bad experience with one or the other but from my decades long experience with them I’ve had no issues and they are easier to work with compared to other brands.
So where can we split hairs? Fans? Seasonic uses the go to Hunag Hua FDB fan while Corsair uses their in house designed NR140HP FDB. Both should easily outlast the warranty. Corsair fan is slightly better in noise in the mid range but neither is considered loud.
Cable length varies per cable as they trade longer length depending on the exact cable.
Voltage regulation is excellent for both.
Hold up time? Corsair easily passes ATX 3.0 (3.1 is lower than 3.0 which kind of sucks) while Seasonic is even slightly better than the Corsair.
Efficiency? Corsair RM1000x did platinum while the Seasonic almost hit it, does it @ 230v.
Also in all fairness, all my PSU have come from either Delta, Seasonic or CWT and virtually all from the latter two. Be it from Antec, PC power & cooling, Corsair, Seasonic, zalman, etc., and my current two PSU are Corsair (CWT built) and Seasonic.
For me? I hate noise so less is always better for me. The RMx is a hair better and the Corsair/CWT QA & QC is top of the line as is Corsair’s front end of the business. Seasonic is no slouch in either.
For you? 9950X3D & RTX 5090, gaming wise power draw would be around 500-575w. Both PSU will easily handle spikes. Efficiency? Both would be excellent and equal, fan noise is a win for Corsair but the unit will be hotter due to the fan spinning at far less RPM. Seasonic has always been slightly aggressive on fan speed. That said, you are a Seasonic guy. Go with the Seasonic and I know you would like the extra 200w of head room.
Underdog Pick Super Flower Leadex Gold ATX 3.1 (does platinum and pushes the “Platinum Pro” in performance)
Very Informative post as usual. I loved all that info
Seasonic is ATX 3.0 in the US sadly. They will not have the ATX 3.1 till Q4 of this year. The Corsair RM1000x is at 3.1. But its 200w Less? the headroom is nice and I want a PSU that will last me years to come. Problem I have with the RM1000x is the way we are going with PC parts? If I want something slightly future proof the 1200w may make more sense. Even if 1000w is fine now. I may need the 1200w later. You follow?
As a side note the only other corsair I could look at similar in price is the RMe Series RM1200e. This is also ATX 3.1 and the exact same price as the Seasonic Vertex GX1200. I did really love my Season Vertex 1200w though. Even though it was ATX 3.0.
Only a 1000w a smart buy atm? Opinion? 
I completely get what you are saying but some things to keep in mind
- both PSU are ATX 3.X so the 12v will handle spikes up to 200% along with better voltage regulation than prior ATX versions. Poor OCP would be a bigger problem in your situation (neither PSU has that issue) than lack of power,
- these PSU are 50c rated quality units designed to handle full load 24/7 for their warranty. Running at 60% on a 1000w unit is a nice jog to them.
fine unit but cost cutting was done to it as not to compete with the RMx. Capable to handle your needs but for you, I think you want higher performance.
Like I said, you like Seasonic. Get the Seasonic. Just realize if that 3.1 is coming in Q4, it’s yet to hit the water and they will most likely delay shipping. You can play around a little bit on product cost to lower tariffs but it’s far easier on something like a chip as opposed to a PSU.
at this time? Yes. It is capable and if you swapped out one of the PSU for the other you would not know the difference? No, unless you were running completely silent PC. I also have my doubts on the supply chain, we are playing around with product cost but we luckily imported most of our stuff already. Our import company has lot of shipments on hold right now from many other customers.
Oh I cant wait for that. I need it now. Im buying it within the next 48hrs.
So its Corsair RM1000x ATX 3.1 or Seasonic Vertex GX1200 ATX 3.0 If your advice is still just to get the Seasonic? I will do that. I wont consider the Corsair RME series for reason you mentioned above.
on a modular unit the real difference between ATX 3.0 and 3.1 is the pin out on the PCB. For a fully native cable unit or one using the dual 8-pin, the ATX 3.0 unit immediately meets ATX 3.1. So the difference on that Seasonic is the PCB header. Just make sure the 12VHHPWR cable is properly seated and you are fine.

I had not looked into ATX 3.0 vs 3.1 yet. Mainly because I didnt expect to be replacing my PSU already If the difference its just the PCB connector thats not biggie at all.
Pulled the trigger on the Seasonic Vertex GX-1200. Thanks

12V-2x6 connector is different in pin lengths. So on the GPU 12V-2x6 side if it senses open pins it will not draw power as a protection feature. If pins are engaged it sends an all clear message. ATX 3.1 has this feature for safety (to avoid the whole melted cable) while ATX 3.0 uses the older pin out and doesn’t hence why I said just make sure the cables are fully seated.
basically, because a few people half assed the cable connection from the PSU to the GPU and some melted this new ATX3.1 feature will prevent the GPU from drawing power until that cable is fully seated. It’s nice but not a deal breaker. Anyone is better off with a quality ATX 3.0 PSU than a mediocre ATX 3.1.
Push the the cable into the GPU until you hear the click and it’s a non issue. Use the cables that came with your PSU (even the same brand/oem PSU can use a different pin out on the header) and don’t use after market cables unless they specifically come from the brand/oem for your specific PSU.
The 12VHPWR & 12V-2Ă—6 plug side have not changed. Same cable on that end.
*edit also hold up time was dropped from 17ms to 12ms at full load. Intel changed the wording at 80% from “required” to “recommended” but stayed at 17ms.
This should be common sense but sadly its not.
This right here is what I was unsure of ATX 3.0 to 3.1.
PS> I canceled my Amazon Order of the Seasonic Vertex GX-1200. Mine was the Seasonic Vertex PX-1200 which was Platinum rated. I got it on sale for the price of the GX.
Well Guess what! A buddy advised me to Call Seasonic CS and see if they would RMA it. He said “dude the worst they could say is no. But if they RMA it anyway? You come out ahead. Worth a try.” So I took his advice and called Seasonic anyway clearly expecting a No. I called Seasonic CS and honestly explained to the rep what happened. The rep said ouch thats saddening knowing its one of our highest quality units too. The Rep then asked “is there any scuffing or physical damage to the unit at all?” I said no. Explained it fell off the table and landed on carpet. Not a scuff or mark on it. It just wont power on at anymore.
The Rep Said “So what you are saying is the unit just won’t power on anymore and there is no sign of physical damage? In that case I could probably Approve an RMA for you. Would you like to start that Process?” Guess who just got RMAd Just after getting off the phone I got an email saying my RMA was Approved. Best Customer Service I have seen in a LONG time
