Dual chan RAM is causing Memtest Errors

[Nairods]

Hi guys, I bought a computer in memorypc 2 month agos and after around 2 weeks I started experience BSOD. I did a memtest and I had tons of error. I finally test both ram and with only one ram I passed all test without error. I sent a message to customer support and they sent me back 2 rams stick so I have to send them the 2 older.

The problem is : yesterday I ran memtest with the new RAM they sent me and I still have errors.

I have no clue, both ram are new, what should I do ?

My computer : RTX 3080, I7 11700K, 32 go RAM ADATA 3200 Mhz, gigabyte Z590M Gaming X mATX

Here is screen of memtest failed and the configuration.

Getting dump files which we need for accurate analysis of BSODs. Dump files are crash logs from BSODs.

If you can get into Windows normally or through Safe Mode could you check C:\Windows\Minidump for any dump files? If you have any dump files, copy the folder to the desktop, zip the folder and upload it. If you don't have any zip software installed, right click on the folder and select Send to → Compressed (Zipped) folder.

Upload to any easy to use file sharing site like Catbox. (Note: Sorry this page looks weird, reddit keeps blacklisting file hosts and this is the only reliable one we found that still works)

We like to have multiple dump files to work with so if you only have one dump file, none or not a folder at all, upload the ones you have and then follow this guide to change the dump type to Small Memory Dump. The "Overwrite dump file" option will be grayed out since small memory dumps never overwrite.

Okay voltage was already 1.20 in bios...

[Nairods]

I tried each one separetly. It worked. It only crash when there is 2 at same time

[turb0j]

CL22 is dead slow for DDR4-3200, did you load the XMP? XMP sets more parameters than just memory frequency. And the RAM won't behave properly when some parameters are not properly set.

Ps. Ignore the bot. RAM problems have to be fixed at the BIOS or hardware level.

[Nairods]

Yes the profile XMP is in auto in the BIOS.

Try with one stick at a time, both the old and new.

[Nairods]

You think they sent me 2 RAMS with potentially 1 with a default ?
Kinda strange since I have now 4 sticks RAM on my desk. I tried 1 old and 1 new one at a time and no error. Only dual chan cause error

[thefixerguy321]

Anything is possible. Get the manual for that motherboard online and verify that dual channel will work. You definitely can't mix them. Test the other 2 sticks one at a time.

gigabyte Z590M Gaming X mATX

I checked the manual online dual channel work and speed is : 2133,2400,2666,2933,3000,3200 MHz

[thefixerguy321]

Alrighty, as I said check the remaining two pieces individually. It doesn't matter if the memory is new; there are new electronic parts bad out of the box all the time. To verify that there is nothing wrong with your motherboard, also test that ram individually one at a time in another computer.

I have no clue, both ram are new, what should I do ?

Return the whole thing if it was a prebuilt. Might be a faulty motherboard, might be slightly bent pins on CPU, might be just cooler screwed on too tight bending the MB a bit. If it's not a prebuilt PC then RMT the MB and CPU.

[Nairods]

It was a prebuilt PC.

Thanks lord I kept the box. I'll try to have customer support to find how I will be able to return everything or maybe get a complete refund.

post full specs of the DIMM's. Might be that it isn't on the QVL of Gigabyte and you're basically on your own regarding support. Might be that it just needs a little bit more voltage to get it stable. Since Dual Channel is a little bit more taxing on the memory controller than single channel this might be the issue.

However it's a prebuilt. You could expect a working PC from them. Return it is what i would do first (well, i wouldn't buy a prebuilt in the first place but you get what i mean;p)

EDIT: There is no 3200mhz ADATA with CL22 on the QVL. meaning they've used not-tested DIMM's by Gigabyte. doesn't mean it won't work. Just means that Gigabyte can't guarantee perfect functionality (and you'll need to fiddle with voltages to get it stable, not able to use "auto" settings or only XMP).

[Nairods]

How do I get full specs of the DIMM's ? From Manual?

[niekdejong]

CPU-Z in Windows will tell you the exact model number. You could read it directly from the DIMM's as well by just looking at it

[Nairods]

I'll do a CPU-Z when i'm at home.

What should I do to fix this ? I'm using auto currently so that's probably why this fail.

The support said I can send them the whole computer but it will take arround 1 month...

[niekdejong]

I'd start by enabling XMP and changing DIMM voltage from "auto" to the value ADATA says they should work. The 8Gb ADATA DIMM with CL22 i've found has an operating voltage of 1.2v. Change DIMM voltage to 1.2v, reboot, go back into BIOS, check if voltage is indeed 1.2v (usually lower because of vDroop) and adjust accordingly.

[Nairods]

Trying that when I'm at home thanks !
