Hi. I am plannin to buy Intel Core Ultra 285K and rtx 5090. But dont know about ram. 32GB DDR5 should be enough or buy 48GB DDR5? Thx
 
There few things easier to upgrade than RAM (for desktop) and there is an outside change that 32-64, etc... stick get cheaper, not a big need to overthink, specially not months in advance, how well 2x24 will work on a new chipset-mem controller, etc... we do not know, how much cheaper 2x24 will be than 2x32 at the moment of purchase to even start to consider them and so on...

2x32 are so much more common (volume leading to cheaper) that the price difference was not worth considering in my last build.

Seem more possible to be worth it now:
https://pcpartpicker.com/products/m...t=price&page=1&S=6000,8400&F=6000000,10228435

But still $178 for 2x24 vs $205 for similar 2x32 6400 CL-32 stick kit, $27 for the 16 extra gig...

would probably end up on the specific deals on kits that day or if you want to go 7000mhz+

so take 2x32 or 2x24?
 
I don't know about the latest gear but historically, the more RAM you have, the hard it is to run at higher speeds and my harder, I mean you need more/better power and cooling.

I'm thinking fast 48 or 64 for my gaming system - 128 is for people who do boring things

Wait.

This is going to be one of the worst releases in recent memory to buy ram ahead of time. It looks like there are going to be CAMM2 boards and CUDIMM support for Arrow Lake. I have no idea what will be best, and it may very well depend on memory size. CUDIMM sounds like it may clock the highest, but I'm not sure it'll be able to beat CAMM2 if you have more than one DIMM per channel or one rank (so more than 48GB) and it sounds like it may run at higher voltage. Sizes are also fuzzy except for regular UDIMMs. No clue on CUDIMMs, CAMM2 supposedly goes up to 128, and with regular UDIMMs you should be able to go up to 4x48GB for 192GB. At any rate I'm not buying anything until I get more info. On that note, I'm definitely not buying ram before I decide between a Ryzen 9 9950X and Core Ultra 9 285k.

If you really, really must jump the gun and buy something before the CPUs are even announced... 2x24GB DDR5-9600 CUDIMMs.

@hu76 Intel says the Ultra 9 285K is slower at gaming than the 14900K.

80 less watt than a 14900k in gaming would put it in 14600k-12700k- 5950x territory I think (90w):

I am not sure if it is what Intel is saying, they always have for each release a showing in efficacy gain, by telling at what wattage does the new generation need to use to match the previous one, but could be (would be a bit strange to make a giant slide being proud of it), they had slide like that showing a 12900k matching a 11900k using only 65 watt.... but they always showed the +30-40% at same power as well, so maybe, otherwise they would not show it beating barely the 9950x.
 
why on Earth would you want 48GB of RAM for?...do you think that's going to make a difference in gaming?...you always go to extremes with your hardware building

for more future, but 32gb ram will be ok?
 
32GB is fine. 48+ is wasteful for a gaming machine today but decide if it's worth the extra $. Knowing you're probably good on RAM until the machine is obsolete is worth something. 64 GB will last until DDR6 and new platforms are knocking on the door.

Yea but financially you should probably go cheaper. Won't be worth having the best gaming pc if you live in a crap hole and need another job.

you're buying a smaller house so you can buy a better PC?...sounds backwards to me
 
how many "houses" have you "bought and sold" this year? iirc this would be the third?
