You want to get those sticks hot..
not what I asked. I need to know if I move in the right direction, so is 500% better than 7% in terms of stability or is both equally unstable?
To me they both useless thats why you need to test "LONGER" Even 5,000% or 6400% i will scratch my oced and see again.

Well if you get errors at 7%, you need to increase VDIMM or IO/SA. If you get errors at 500%, heat is more likely the cause.

Thats the problem you get a hit at 800% then you think is ok. Then do same settings as before and get hit at 7% thats why you have to make sure those sticks get hot. Cpu aint stable, sticks not hot enough.. A vdroop somewhere,somehow etc etc..

The trick is long period of time testing.

What are you? Have you tried the 2R 4400 16-16-2T? We are, and it turned out to be at 4666 17-17-2T 1R. Used 3200 14-14 XMP modules, settings 4400 16-16-34-2T 1.55V + 10900K 5300/5100 + Z490 MEG UNIFY

Thats cool, what board i mean what io/sa and cooling used? :rollseyes: nah i don't care for that..



at this point really looking the last 20pages back this topic has become a top 10 3dmark type of topic....


But, Specially...
wheres the hci run?

If you got a bsod notch back or raise voltage be careful if you dont want to reinstall os... Are you sure you doing this tests on stock or a well stable overclock? You overclocking memory what worked before it can be different now.. Remember that.. That error in particular mostly memory

Remember: There is no stable, just degree of stable

You can get memory stable memory in very cold environment for hours, but the same "stable" can get very unstable if the environment is just a few degrees warmer.

So if someone is posting HCI "stable", the best is to show all the variables. Ambient temp, watercooled ram, water cooled cpu, water temp etc...

Stable in given environment

As I have said many times: RAM stability is not about duration or percentage, but temperature!
You can pass days of stress test and crash in few minutes in gaming if your sticks get hotter because of the GPU.

My advice to test stability:

1) first check your settings by doing a rapid testing of timings/frequency by booting to Linux USB (search GAST) about 5 minutes should be enough, just to avoid to kill your Windows by mistake

2) slow your case fans, boot to Windows, use your GPU to heat up your RAM sticks in background and do your stress test while monitoring your RAM temp, the first errors will appear when memory cells loose their electric signal quality because of the heat.
That will be your maximum safe temp before risking memory corruption.

3) adjust your settings if you're not happy with the result and try again

Keep some safety room max stable temperature for daily usage

Default XMP should be stable until about 60°c on PCB (85°c in ICs from JEDEC standard)



Edit: fix bad chars from smartphone

My sticks can be watercooled fyi.. But i dont have them like that xD..
Ambient is way over 90F the other day was almost 100f..

Stick to the topic rules or open new one something like top 10 aida64 mem benchies... XD

This is a stress testing topic..
