ddr 5 is a problem... level 1 tech

[thrasher_565]

video 1 top 16:00 talks about desktop ram mostly talking about the server mb and gskills ram with no heat spreaders. 

video2 bottom talks all about ddr5 and how it works as well as other things. hence the title...

 

ya i use to scream at people for cooling but with lower power cpus i let off a bit...but now i should start screaming again. air flow is needed.

 

so many pc problems these days... play wack a mole

Care to expand on what the claim is without requiring people to watch the video?

I watched one of them abit and in the video he points out how DDR5 memory sticks, running at high speeds, cramped togheter in a case with bad airflow will cause them to overheat and give memory error problems and instability, bluescreens.

 

He points out design flaws in some sticks where important components can easily get overheated. 

 

He's also giving some thoughts that in nearby future if ram will get any faster and generating even more heat perhaps they'll need more error correction like ECC sticks have.

 

When it comes to overheating most new people tend to think the CPU and the GPU are the main suspects, and disregard that it might be the memory overheating.

 

I didn't watch both of the videos, only one of them abit.

thought long time ago when ddr5 came out they ran hot but i think people forgot about it.

water cooling it is hard because most have glued on heat spreaders and you pay more with ram with out one. 

 

has to do with the chip on top middle getting hot and was put at the top for better air flow. using some shroud works better with ram with no heat spreader. a small fan blow at it seems to help the problem.

 

didn't really go in to details how much cooling one need in the case. so really more questions then answers  

 

but i mean you live in a place that hot or summer time and might see problems. 

 

its kinda like the nvme over heating and gpus dumping its heat at it. 

 

4 sticks of ram also cause more heat then 2 sticks kinda a problem being avoided. 

 

also is it for the really fast ram or ram oced who knows... 

 

oh he dose say desktop need more testing as he deals mostly with server stuff.

DDR5 is supposed to throttle if it overheats, but this is broken on some ASUS Threadripper motherboards so there is concern it may be other boards too.

 

Also desktop DDR5 doesn't necessarily have the same protections so it may be a good idea to ensure the RAM has good airflow as it may be a lot of people thinking their RAM is faulty is actually it overheating, as DDR5 runs a lot hotter than DDR4, not least because of its on-board voltage regulator.  So much so that RAM without a heatsink but good airflow is less likely to have problems than RAM with a heatsink and poorer airflow.

It is long known that at higher temperatures silicon can become less stable. Product specification on operating conditions include that, so in normal use, that margin is accounted for. High in-spec temperatures are not a problem.

 

Moving it onto ram, the question then is, at what temps could that start to become a problem? I just started hwinfo64 and will do some routine gaming shortly, since my system hasn't been on long and is probably still warming up. The ram reports "SPD Hub Temperature" and has a yes/no on "PMIC High Temperature". I do have 2 sticks in a 4 slot board, so there is little space between them. I have a FE GPU so the exhaust of the blow-through fan does put heated air into the ram area.

 

I couldn't find a written spec for my ram's operating temperature. The SPD reports "Temperature Limit 55.0 degC (high limit), 85.0 degC (critical limit)". This can be found if you save the full report from CPU-Z. Search for "SPD" and look around there.

 

Edit:

I did some light gaming. These games are capped at 60 fps so don't push the system that hard. Peak temp recorded 38.2C, peak power 4.25W.

8 minutes of Prime95 Large: Peak temp recorded 54.2C, peak power 6.25W. Temps might not have topped out yet as they were gradually rising over time.
