Memory heat Issue?

[JamesJB]

Hi I brought Corsair Vengeance RGB Pro 64GB  on Aug 27, 2020.

Had 2 of the sticks die on me and have 2 remaining.

 

I'm not sure why but depending what games I play the memory will hit 93c.,everything else temp wise is fine.

According to my motherboard's Live Dash OLED it reports the memory is 93c.  The Motherboard I have is;

Asus Motherboard

I am just scared that one of these days something might happen  😞

I might just buy this come July Corsair Vengeance RGB Pro 64GB (2x32GB) in case the memory I have at the moment might be going bad like the other 2 I had.

My system btw is;

--(My System)--
Windows 11 Pro
Asus TUF Gaming VG27AQ 27” Monitor
Intel i7-10700K 5.1 ghz
NZXT Kraken Z63 280mm AIO Cooler
Corsair Vengeance RGB Pro 64GB 4 sticks of 16gig
MSI Gaming GeForce RTX 2080 Super 8gig
ASUS ROG Maximus XII Extreme Z490 Motherboard
EVGA Supernova 850 T2, 80+ Titanium 850W
NZXT H710i ATX Mid Tower PC Gaming Case

--(VR)--
HTC Vive Cosmos Elite
Oculus Quest 2

I could use the help if possible,I mean if it can be fixed then I won't need to buy new memory.

Thank you in advance for any possible help.

Could really use some help on this please  😞

usually memory temperature is very dependent on the internal case temperature and to an extent, on RGB lighting.

If yours reach 93°C, it could be caused by bad airflow in the case. your AIO and GPU have their own fans so it may not be obvious by looking at them, but components being cooled passively may be toasty hot.

You could look at motherboard temperature sensors like the VRM, PCH temperature, or the M.2 drives if you have some. temperatures in the 40-50° range would be typical.

Also some lighting schemes tend to warm up the RAM, namely white lighting. I often saw a 15-20°C increase when using white lighting on ram sticks. But still, that doesn't account for the excess 50° you are seeing.

Maybe detail a bit how many fans you have, where the AIO is mounted (front or top), how the fans airflow is set up (intake, exhaust), and obviously, check your dust filters. If the front one is clogged, you'll have problems!

3 fans in the Front 1 in the back,the front are sucking in air the back is sucking out.

The RGB I have is Red.

I have 2 M.2 Drives.

The AIO is on the Top sucking air in. That has 2 fans,No RGB on that.

This is my Setup minus 2 sticks of ram had 2 die on me 😞

No dust build up,I clean it out like once a month.

Looks like ill have to buy new memory 😞 

Hopefully that fixes the problem.

[LeDoyen]

Without knowing the internal case temperature when gaming, and maybe the ram voltage, it's difficult to say anything. I don't see why DDR4 would reach that temperature without a toasty case or ridiculous voltages applied to them.

I agree and think you need to make sure the environmental conditions are fully understood before making another purchase. Even if the heat spreader was improperly assembled, it is highly unlikely both modules are affected in the same way and wind up the same extreme high temp. Blowing warm air off the radiator may add to baseline temp and then if the gpu waste heat can’t be evacuated fast enough it may get quite warm in there. However, I’ve never seen anyone report 90C+ ddr4 temps without running RAM tests at extreme voltage and passive cooling only. 
 

M2 drives are also fairly heat sensitive and will rise with interior case temp. What do you see on those?

90C on ram is bad. I have never seen ram that high unless it was being benchmarked and ran hard in an air tight case. DDR4-3200 should be around 35-65 on average. 

You mentioned you have your AIO up top sucking in. That would mean all the hot CPU rad air would be blowing over your ram. I would change the AIO to push the air OUT of the case. 

Or move the AIO to the front.

While idle both M.2 sit around 48c and 49c

Not sure while gaming.

I don't do any Ram tests at extreme voltage. When I built the system I just used XMP.

 

Check the links above on how the case is if possible.

I do notice it does get warm in there while gaming on some games.

I thought about having the air being sucked out through the AIO but wouldn't that suck the warm air through the rad and make the CPU temp go high?  Just curious.

When I first built the system i was going to put the AIO in the front but it wouldn't reach 😞 also it would of been in the way of the Graphics card.

I didn't mess with voltages I just enabled XMP.

The CPU temp while idle sits at 28c when gaming and depending on the game it will go as high at 40 to 50c

The GPU temp depending on game and graphics settings will go up to like 65 -81c

Ok guys I have the AIO fans pulling air out of the case towards the radiator now and I moved the ram to DIMM 1 and DIMM 3.

The temp in the PC don't seem warm any more and the memory seems to stay around 40c or a little higher but no where near 93c anymore.

Another thing I noticed when I put X4 Foundations to Ultra settings the GPU doesn't go up to 80 - 81c now,it seems to top off at about 71 - 74c.

I still may get new ram though cause I had 64gig ram and I only have 32gig now.  I did hear reports that Starfield might need 32gig on the high end.

[LeDoyen]

try to get 2x32 gb if you must. There's no benefit on 10th gen going with 4 sticks, and it's way easier to cool than having 4 RGB sticks slapped against each other.

So apparently your ram was cooked between the GPU heat and AIO heat dumped onto it and the back fan wasn't getting rid of it fast enough..

Y'oull probably see that your main NVME drive just above the GPU is also running a lot cooler. These throttle above 70°C so i imagine it must have been running slow for a while!

Well done! 

[JamesJB]

I did have to change the ram back to DIMM 2 and DIMM 4 cause for some strange reason everything seemed unstable and Diablo 4 kept stuttering and crashing  😞

I do plan to get 2 32gig sticks instead of 4 16gig sticks.

[JamesJB]

Btw the 2 NVME drives seem to lose a few degrees on idle not gaming the are around 40c and  43c now.

[LeDoyen]

usually, from the cpu looking to the right you have to leave one slot empty, one stick, one empty and one stick. your motherboard manual will tell you what slots to use for 2 sticks. 99.9% of the time it's those two.

Oh I understand. Some people told me to install the memory furthest from the CPU others tell me closest to the cpu  like DIMM 0 and DIMM 3 or others told me DIMM 2 and DIMM 4,not sure why for that a little confusing.

For some reason now if I put it in DIMM  0 and DIMM 3 the system becomes unstable not sure why but if I put them in DIMM 2 and 4 everything seems fine,weird.  Now if I have 4 sticks of ram the system doesn't become unstable.

Don't understand why the system would become unstable if I put the ram in DIMM 0 and 3,other PC's I had never did that.

1 + 3 is wrong for nearly every motherboard out there.  Most have very specific arrangements for the exact number of modules you are using.  It's almost always slot 2 + 4 for any 4 slot, right of the CPU board.  Motherboard trace functionality is beyond me, but an easy way to think of it is priority slots.  If you put something in 1/3, it is also expecting something to be in 2/4 for signal routing purposes.  Often you can't even boot in 1/3.

here, from your mobo's manual :

In practice, any combination should work, mostly without XMP, and sometimes in single channel instead of dual.. so at slow speed.

with only two sticks, you must use the slots indicated in the manual. these are the two that will allow the highest frequency, while staying in dual channel mode.

For most motherboards it's A2 + B2.

A1 + B1 may work, but will be unstable (more signal noise).

any other combination is single channel (A1+A2, or B1+B2), so you basically slash in half your memory bandwidth and often can't enable XMP without crashing.

Oh ok thank you now I know why stuff kept crashing when I had the sticks in A1 and B1.  And the system being unstable.

Sorry I know its been a while but need to report on something.

Now instead of the Ram warming up like crazy the CPU is doing it,it will go up to like 65 - 66c while gaming it used to only go up to like 45 - 50c.

I am gonna be getting a new bigger case which is this;

CORSAIR iCUE 7000X RGB Full-Tower

and a new AIO

Corsair iCUE H150i Elite LCD XT

 

I have also noticed since I changed the AIO to sucking air out that one of the fans on the AIO look like its spinning slower than the other,maybe one is about to go? I hope not 😞

My current AIO is this one;

NZXT Kraken Z63 280mm

 

One more question based on memory I'm thinking about getting this memory next month,want to go back to having 64gig ram;

Corsair Vengeance RGB PRO 64GB (2x32GB) DDR4 3600 (PC4-28800) C18

will I see any difference in performance with the faster memory? also as you can see its CL18 and the current memory is CL16 will there be a performance hit cause of it being CL18?

Corsair Vengeance RGB Pro 64GB (4x16GB) DDR4 3200 (PC4-25600) C16

Only have 32gig since 2 died on me 😞

 

Thank you again for any help.
