More CTD's with DDR5?

[altenae]

Anyone noticed more CTD's when going from DDR4 to DDR5 ?
Thanks 

 

[St Mawgan]

Not at all. 

[Nemo]

Nope. But if you upgraded to DDR5 you have a new MB too. So looking only at DDR5 vs DDR4 makes no sense imo.

[SierraDelta]

No, not at all.

Yes I know..
I am upgrading to the I7-13700K and a Z790 motherboard.
These motherboards can be bought in DDR4 or DDR5.

No, there shouldn't be.  If this happens it is probably just a problem with set-up (overstretching the RAM speed, refresh rate, or not enough voltage).

One common problem is buying two 16GB kits rated to a certain speed.  This has little chance of holding the speeds when lumped together as 32GB - believe me, I have been there it it was a world of pain until I figured it out!  Occasional windows blue screens and just some complete drop outs from MSFS within seconds.  16GB pack XMP profiles simply won't work on the full 32 GB unless you buy an actually combined 32GB kit rated for those speeds.  

Use Memtest86 in your Bios software and leave it for at least 20 minutes (about 4 cycles).  If you see red failure lines, you need to tweak the speeds down and make sure the RAM voltage is towards the top end.

For my Patriot DDR4 4400 kits, I had to go all the way down to 3800 in the end to get the whole 32GB stable.  At least I could lower the timings and voltage a both though! 
Dead stable now - no problems since, and confirmed by all green in Memtest86 after about an hour while I had some dinner!

So are you saying that this memory will not run on 6000 with XMP ?

At the moment I am running DDR4 3600 CL16 with XMP and the 3600 runs without any issues.

I've had CTDs when trying to use XMP with my 4000 rated DDR4 ram.  However,  my motherboard supports trying multiple settings in bios - I currently have mine clocked at 3867Mhz and have not had one crash since.  

Something to consider.

No!  That kit is great.  It is a full 32GB kit rated for that speed - all fine.  My point was some people try to use two separate 16 GB kits (four sticks) and it is very unlikely for them to work at their rated speed then when lumped together as 32GB.  This is a common problem and major cause of disappointment!

6000Mhz is only possible in optimal circumstances. Running the RAM at that speed is considered an overclock considering 12th gen Intel supports only 4800MT/s.
So while 6000Mhz might be possible be prepared to use more conservative settings since MSFS is quite unappreciative of overclocking.

I run everything at stock here. There seems little to be gained overclocking modern equipment and the pain is more than the gain (if any).  Going back a few years, you could overclock a lot by 20% or more in some cases, with the only problem being keeping your temperatures down.

XMP hasn't worked for me since the 90's.

I choose for a. Asus Rog Strix DDR4 version instead of DDR5 about a year ago.

Because of the 13900 cpu I had to turn down the 32Gn GSkill 4266 MHz cas 17/18/18/39 memory to 3200 MHz but I lowered cas to 13/14/14/32….

The 13900 series will work with DDR5 4800 MHz but the timings are so much higher than DDR4 that the complete set is slightly slower icw MSFS …..

Probably the right way to go Gerard.  DDR4 speeds above 3200 don't  really deliver much, with 3600 probably being the top speed of any value.  Diminishing returns after that.  Better to play with the latency timings then like you have - they do deliver benefits.  This has all been tested and proven by Linus, Jay, and Gamers Nexus etc.

You have good numbers there.  I am going to try to drive mine down a bit but it takes so much time to test in between each adjustment.

Just odered a new PC with Kingston Fury Beast 32gb (2x16GB Kit) 2 of for 64GB 5200MHz Non-ECC Ram Black heat spreader, so is the above comments goping to apply to my purchase?
