Pointless for gaming

"The question may be, is this literally the fastest memory you can get? At retail, absolutely. In terms of raw MHz, it is. Practically speaking though, unless you’re already getting the absolute best in every other part of your system there’s no reason to spend such a huge amount on memory.

Corsair told us in their testing that actually the lower end Ryzen 3000 processors may have more success with memory stability, due to only having one chiplet, which puts less stress on the internal fabric. Higher core chips with two chiplets may have more issues due to overall heat and stress. It also comes down to the integrated memory controller on the chips: some are strong, some are weak, and it's a silicon lottery. There might be a day where memory vendors have to sell pre-binned CPUs with their high-end memory in order to ensure peak performance.

With this kit, Corsair is sending a clear message. The company wants us to know that their custom 8-layer PCB internal screening process and anodised aluminium heat spreaders are capable of producing memory that hits the highest speeds on the market. This is a team effort helped by AMD’s processors and MSI’s motherboards, but it’s undeniably very impressive. It's just a shame that AMD doesn't have a big APU to pair with it, as that's where I think we would see the biggest improvement in performance."

Who would spend that kind of money on memory to pair it with a system running an APU?! Am I alone here thinking that is dumb?
Would have to agree at $1200. That’s a nice 2080TI. I think the author meant for purely testing purposes.

This stuff will fall in price although I doubt it’ll be super common. We’re already heading for DDR5.
 
18-26-26-46 latency. Yikes.

I'd rather spend (a lot less) money on DDR4-3200 to 3666 with 14 to 16 latency.
Going by the CAS latency access time on 5000 MT/s with 18 CAS is 7.2 ns. 3200 MT/s with 14 CAS is 8.75 ns. 3666 MT/s with 16 CAS is 8.73 ns. Of course, you're starting to look at a severe increase in cost for not much return above a certain speed and latency.

In this particular case, I believe the decrease in infinity fabric speed (for 5000mhz) is a primary argument for 3200/3600 cl14 having perhaps better latencies on Ryzen 3000

Also, here is a video of a similar gigabyte kit @5000mhz. In the video, Derbauer pits it against such kits and I believe the 3200/3600 cl14 kits do indeed edge out the 5000mhz kit in terms of ryzen latencies. (His video shows the 5000mhz kit @ 18-28-28 has an aida64 memory latency of 75.7ns)

Responding to your edit:
Keep in mind that if you're running AIDA64 on an every day Windows install the latency is affected by all the shit running in the background.

Yep...this RAM makes zero financial sense for a gaming PC that needs as much GPU power more than anything else.

True and CPU frequency too which makes it hard for apple to apple comparisons.

On another note, I think an interesting use case for such fast DDR4 would be if it were in quad channel on a threadripper setup. That would be some insane read write bandwidth. Wouldn't do much if any good for games though.

Eh?
They mean single chiplet stuff like 3600-3800... not APUs lol.
 
Its cool to see this but....

A cas 14 3600mhz will stil rape this overpriced junk.

Let me quote what is in the OP's post.
"It's just a shame that AMD doesn't have a big APU to pair with it, as that's where I think we would see the biggest improvement in performance"

What the HECK did YOU read?!

I don't know about them, but I took that to mean a APU with the GPU side bigger than any of the existing retail models and maybe some HBM or GDDR6. An all out 125w+ APU with gaming/rendering performance equivalent to a mid-tier GPU will come some day.
 
Just came from Newegg to check out the price

Also includes that cool looking cooler ... all for just $939.00 :confused::eek::ROFLMAO:

CORSAIR Vengeance LPX 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 5000 (PC4-50000) Desktop Memory Model CMK16GX4M2Z5000C18

I took it to mean you will see the greatest benefit from this memory when using an APU because the additional bandwidth would actually matter. Of course that's just an academic exercise because the money is still better spent elsewhere.
 
I do miss the old GTX line. GTX2 was my first experience in extreme high end ram. Still have some GTX4 sticks here somewhere.
 
When I bought the DDR 1 corsair sticks with the leds on it, though that was super exclusive....I am disappoint
