G.SKILL Announces New Ripjaws S5 Series Low-Profile Performance DDR5 Memory

[londiste]

I don't think there's a standard for low-profile but people will use LP DDR and LP-DDR, more often the manufacturer will add is as a suffix rather than a prefix, eg DDR4-3200 LP

Low profile is somewhere around 31-34mm and very low profile is 18-19mm. The standards for those are primarily for server space.

Doesn't it depend on how much airflow, how much heat from the other parts, the voltage? it's not as simple as that

It does. but getting ambient high enough to cause problems with DDR4 chips at 1.35V or lower is easier said than done

Unless you have something blowing very hot air onto the DIMMs, that's unlikely. They're their own PCB, so thermal transfer from the motherboard will be minimal; air off of most heatsinks isn't likely to exceed 50 degrees (typically less). The main source of heat will always be the heat the component itself generates, as nothing else has a direct thermal pathway, and even warm air will still cool a component as long as it's cooler than the component itself - it will just cool it less. The only DDR4 I've heard of being thermally sensitive is high clocked, high voltage Samsung B-die, which apparently doesn't like exceeding 50°C, but even that takes some doing.

don't underestimate people using high TDP cpu's with shitty coolers (or even stock coolers) and all glass cases with lots of RGB and no air intake.

anyway, what are heatsinks

Well, in that case you have worse problems than hot RAM. And besides, are you claiming that these same people run high memory overclocks?

Question: The last picture shows a non-linear pin-layout; (same as can be seen on the VLP pictures posted by #6. I assume that that is an error? (since the first 4 pictures is linear? (or maybe they are showing that it can be used for different standards.

What do you mean by linear? That the bottom edge is flat vs. has a slight curve to part of it? All DDR5 (and DDR4) is shaped that way, it's a part of the standard. The reason why some of the pictures look like this isn't the case is simply that the curve is very subtle and is hard to see from some angles. But it's there.

Hmm true; I think the black pcb on the black back made it look linear.

I have to say, those are the best-looking RAM modules I have seen in a long time. Well done G.Skill.

I have to agree. The minimalist design looks quite pleasing.

It's laughable how standard size RAM is lablelled as low-profile now because the consumer market has been infested with stupid, bolt-on cosmetic vajazzle and twinkly lights.

This is IMO how all RAM should be - unlit so it draws no additional power from your CPU and the normal height that RAM without heatsinks is - like server RAM and OEM RAM.

An extended heat spreader on consumer RAM is like a gigantic rear spoiler on your grandma's Corolla.

That explains all the RGBLED rubbish infecting RAM modules too; Can't have a gigantic rear spoiler on granma's Corolla without neon underlighting, a glittery paint job and spinners too.

I'm really digging the new design style in G.Skill's DDR5 lineup. Very sleek.
