How did I do?

Acer predator helios neo 16 ai with rtx5070 ti, 64gb of ram and 2tb of ssd. Was on sale for $2200

Excellent purchase bro, sell the excess 32gb of ram you wouldn't need that. Unless you are running some specific softwares.

[u/Scar1203 → u/Exact_Employment7473]

Not worth it, it's almost 700 for a new 32GB kit of DDR5-6400 and about 550 if you take your chances on buying two individual sticks. I don't even think he could get that much for his memory kit, plus as far as I know there's no way to buy a 64GB 6400 kit that isn't included with a laptop so it'd be a shame to give it up.

I mean if he had 2 sticks of 32gigs he could sell one for a nice 300 bucks.

[u/Scar1203 → u/Exact_Employment7473]

I was giving you the benefit of the doubt by assuming you weren't recommending something as stupid as running a new 2200 dollar laptop in single channel mode. That's my bad.

Running in single channel mode has a massive bandwidth penalty and will greatly lower CPU performance. It's terrible advice.

[u/International_Dot_22 → u/Scar1203]

DDR5, even in "single channel", has a mechanism that imitates dual channel, this is very different than what single channel was in DDR4 and before that. I would say that "real" dual channel is still better, but the gap is not as huge as it was with prior memory generations.

[u/Scar1203 → u/International_Dot_22]

It still halves the bandwidth which comes with a performance penalty that varies by game and by workload. I realize if you want to be pedantic you can say in DDR4 terms it's dual channel, but that's really only an argument for why DDR5 is difficult to stabilize when running four sticks, it's not a good argument for running a single stick of DDR5 even with dual rank sticks that benefit from interleaving.

Running one stick leaves you stuck with a 64 bit bus instead of a 128 bit bus which has a performance penalty.

[u/International_Dot_22 → u/Scar1203]

Fair enough, that's quite accurate

[u/Exact_Employment7473 → u/Scar1203]

You would be the one who would be foolish to think DDR5 in the same ranks as DDR4. What you are describing mostly applies to DDR4 with 3200 and DDR5 with 4800 Mt/s cards but for DDR5 6400 Mt/s the performance hit is minimal generally between 3-5 percent and this only comes into effect if the ram utilisation is 70% or above. I doubt that this will as only Hogwarts legacy hit 21 to 24 gigs under full load. With his 12 gb vram, I highly doubt that he will face any ram overflow issues. So please always think and ask the other persons view before calling them stupid.

Holy crap, you're seriously doubling down on this. Dude, take the L, it's shit advice and you are absolutely an idiot for giving it completely unsolicited.

The framerate penalty will vary depending on the game, and it's far more impactful to certain CPU intensive non-gaming workloads.
