A while ago I tested my ram using Aida64 Memory test and got these results :
Font Electronic device Technology Screenshot Multimedia


Now a few months later I did the same test and got this result :
Font Screenshot Electronic device Software Multimedia


What changes have been made, I updated the bios from F12K to F12, one of my RAM sticks is lost it's RBG lighting , my RAM is as follows : G Skill F4-3600C17-16GTZR x 4 16gb B Die Samsung modules. I have been thinking of removing the dull stick and going 32GB instead of 64GB, might even improve my RAM overclock which is a measly 3466 Mhz. I am really stumped as to what happened to my ram, Could it be a Windows update? I have Secure boot enabled . TPM enabled via a TPM external module, I have HVCI enabled. I am trying to give you guys as much information available. Is it time to invest in a new set of 4x16GB of RAM, I really would not cause I've spent so much on this build already. Any suggestions is welcome. Thanks guys.

Can you do this test on safe mode please?

Maybe there is a lot services running on background or some apps/services/drivers impacting the latency
I did it in safe mode, had to reinsert the bitlocker key after I was done , nonetheless I got good results on safe mode, what should be. So It is something software related. Dang it.

Lower Uncore (Ring or NB) clock will have some effect.

Background processes will have some effect.

Your RTL is good, but maybe your IOL are high?
What is an IOL ?

Side question: I TPM and bitlocker enabled and how would that effect me reinstalling windows ? Would it be straight up USB mount and install from USB Tumb Drive or would the bitlocker get in the way ?

I noticed something big today, I was messing around in my bios and I turned on VT*d and then I ran the Aida64 memory benchmark and it was very low, in the 35000Mbs write, read and copy, which leads me to believe it has something to do with virtualization settings I applied some time over the past few months, only which is the question. For instance I can't change the settings in device security -> Core Isolation -> Memory Integrity ( it's greyed out ) I can't change it on or off, it's currently set to ON. And Firmware Protection is set to OFF, also greyed out and can't be changed. Not sure if it has anything to do with anything.

Turning on Core-isolation or memory integrity will definitely reduced overall system performance. There are plenty of tests that shows performance impact from having those settings enabled.
Yes I know but the problem is I can't turn off Core Isolation -> Memory integrity , it's greyed out and says only an administrator can make the changes, I am the administrator so there is that. So that's it, thats the solution to my problem, the Core Isolation -> Memory Integrity turned on, and I can't turn it off because it says Only an Administrator can turn it off, I am the administrator thus the problem, I am stuck.

If your RAM is fine in Safe Mode, it just means that ordinary PC use has congested the OS and background programs are pulling down performance.
Not much you can do besides optimizing your PC, or doing a reset. Disable startup programs, uninstall junk.
I have a feeling that Core Isolation -> Memory integrity is the cause of my issue, if I could get it to turn off my ram speed would go back to normal.

Turned it off lol. I think the performance penalty is intrinsic.
If you need the added security for a few things you can dual boot and encrypt the OS drive with core isolation/memory integrity enabled
Easier said then done, ever time I turn it off, and reboot, it turns itself right back on. I can't turn the ######## thing off.

I don't know how many times I can tell you guys, I can't get Core Isolation/Memory Integrity to turn OFF, when I turn it off, it asks for my password and then it says I have to reboot to apply the change, well when I reboot, and I go into Core Isolation/Memory Integrity it's still ON, no matter how many times I try to turn it OFF. And for the BIOS, I have looked through the entire thing looking for anything that resembles VT-X, I only have the 1 option of VT-D which is DISABLED. So I am stuck in a never ending loop. I have tried registry editing , policy editing to no avail. I think my computer just doesn't like me very much :confused:
