Question Should I trust Changxin Technologies RAM?

[SteveGrabowski]

I want to upgrade my system to 32GB of DDR4-3200 and since I can't even run my 2x8GB 18-22-22-42 G.Skill Ripjaws DDR4-3600 at 16-18-18-38 DDR4-3200 was thinking of just picking up a 16-18-18-38 2x16GB DDR4-3200 kit. Probably better to do that than to put the strain of four DIMMs on my i5-12400F's memory controller (which was incapable of running the 18-22-22-42 DDR4-3600 XMP profile on my current G.Skill Ripjaws RAM so I have to run it 17-20-20-40 DDR4-3200). Always thought all this RAM was made by Samsung, Hynix, or Micron but reading reviews of a Silicon Power DDR4-3200 kit I was looking at I see sometimes the chips in it from Changxin Technologies who I have never heard of. Figure that's why the RAM is $59 for 2x16GB. Though the reviews say sometimes they'll get Samsung, Hynix, etc. I can get the same clock and timings in kits from G.Skill and Corsair for $10 more. Are those more likely to be Samsung, Hynix, or Micron? Should I steer clear of a kit known to sometimes have Changxin Technologies chips or am I ok with their chips?

Interesting. I did not know that Silicon Power DDR4 DIMMs used (effectively, third-party / non-major-brand) chips on their DIMMs. That might explain why they end up somewhat a few dollars cheaper.

Given how cheap DDR4 is overall, even for name brands, is risking another Chinese brand for another $2 worth it?

That said, you can get Team Group Vulcan Z DDR4-3200 CL16 2x16GB kit for $61.99 after promo @ Newegg right now, and I've bought some quantity of Silicon Power DIMMs, and never had much of a problem with them either, although I never opened the heat-spreader to see if the chips were Chinese and not Samsung/Micron/Hynix.

And there's always GSKill Ripjaws V for like $69.99.

ChangXin Memory Technologies (CXMT) is Ramping up Chinese DRAM Using Qimonda IP

Looks like they're using modified micron 19nm designs for their ddr4, so they're a few years behind. Probably won't be great for overclocking.

I ran Kingston DDR4-3200 CL16 successfully with XMP on my friend's i5-12400 with H610 chipset. 2nd XMP profile gave him DDR4-3000@CL15 which along with HT off, gave him his best single threaded Geekbench 5 score.

Don't cheap out on RAM.

Ended up paying the $10 extra for some Corsair Vengeance and it turned out to have Samsung chips and is passing my stress tests at the 16-18-18-38 DDR4-3200 XMP profile so I'm happy.

Corsair Vengeance is pretty solid. Itl probably run at tighter timings with a bit more juice.

I'm a bit of a gSkill fanboy but there you go...
