Patriot RAM kits - potential incompatibility with Intel 800-series (Z890, B860 etc.)

[citay]

A few people have reported on this forum that their Intel 800-series-based board wouldn't boot with their Patriot RAM kit. Since that seemed odd to me, I did some further research, and soon found other reports of the same issue, even with different motherboard brands like ASUS and Gigabyte. There seem to be some Patriot DDR5 kits, particularly 32 GB kits of 2x 16 GB, that simply do not want to work whatsoever with an 800-series platform like a Z890 board for example.

People have even gone so far as to replace their board and their CPU, but as long as they kept the same Patriot RAM kit, it just wouldn't boot. Once they have used a RAM kit from a different brand, it booted right up.

Since the other thread where we are discussing this has a rather vague title, I thought I'd make a new thread, where people can reply if they encountered the same problem.

Here are some cases of these I could find after some short research:
MSI PRO B860-P WIFI, BIOS does not load (MSI Forum)
MAG Z890 TOMAHAWK WIFI (MSI Forum, two cases)
ASUS Rog Strix Z-890-A no POST after VRAM QLED (ASUS forum, two cases)
New Build Help - Won't Post Z890 Eagle Wifi7 (r/gigabyte, several cases)
Z890 EAGLE WiFi 7: not posting - RAM compatibility? (r/gigabyte, several cases)
Z890-P PRO New build DRAM light Problem (reddit)
Also several similar threads on German forums.

This message from a reddit thread was the closest to come to an explanation:

Later, this thread made it likely that the problems are caused by DDR5 modules using 1Gx8 density ICs (memory chips), which are not supported by this platform. Apparently, Patriot had or has several RAM kits using these kinds of memory ICs, therefore they won't work on 800-series / Core Ultra.

It would seem that there is no solution other than to replace the kit with a completely different one, unless Patriot support can provide a better solution.

Everyone that was/is affected by this (maybe apart from the cases already listed), please reply here. I hope this can then be easily found by other users and they don't have to spend time and money doing unnecessary troubleshooting. As mentioned, I've seen at least one user replace their board and their CPU over this (which is never a good idea, blindly replacing parts, one or all of them might end up being a complete waste of time and resources). But if we look at the reports, the only thing that makes the system work is to replace the RAM kit with one from a different brand.

Thank you so much for starting this thread and consolidating all these cases. It’s a huge relief to know I’m not alone, but also frustrating to see how widespread this is.
I specifically chose the MSI MAG Z890 TOMAHAWK WIFI because the official support page explicitly lists Patriot 6400MT/s kits as compatible with the Intel Core Ultra Series 2 (Arrow Lake). Relying on that official information, I purchased the Patriot Viper Venom (PVV532G640C32K), only to be met with constant Code 55 and E0 errors across three different boards.
I really hope Patriot acknowledges this firmware/SPD defect and provides a real solution soon. Users shouldn't have to spend weeks troubleshooting or blindly replacing parts when we followed the official compatibility lists.
I’ll be returning this kit and switching brands as suggested. Thanks again for the help! https://www.msi.com/Motherboard/MAG-Z890-TOMAHAWK-WIFI/support#mem

Thank you also for more information in this thread: https://forum-en.msi.com/index.php?...0-with-core-ultra-7-265k.417061/#post-2366339

I've seen this mentioned before, but now it's more official. I have therefore also updated the first post in here.

 

[Paupardo815ca02e9]

I want to provide an important update regarding my previous troubleshooting. I have just tested the system with a Corsair DDR5 kit, and it booted instantly without any issues.

• The motherboard recognized the Corsair modules immediately at 4800 MT/s.
• The Error Code 55 only appears when the Patriot Viper modules are installed, even after trying manual voltages of 1.300V and Slow Training.
• This confirms that the CPU (Ultra 7 265K) and the Motherboard (Z890 Tomahawk) are functioning correctly.
• The issue is a definitive compatibility conflict between the current BIOS version (1AA0) and the Patriot memory kit.

I'm not aware of this limitation.
Yes, the 8Gbit chips were used in the first DDR5 modules (8GB single-side and 16GB double-side) and they don't exist in the production line of anyone for a few years.
But that does not mean the Intel 800 chipsets and the Core Ultra CPUs are not able to recognize them.

In any case, here is the current Micron DDR5 production line.
You can admire the first native DDR5-7200 chips.
DDR5-7200 native means 7200MT/s at 1.1V with CL58.

I'm the second case from this topic: ASUS Rog Strix Z-890-A no POST after VRAM QLED
I wonder if anyone succesfully got any replacement from Patriot. I cannot return my sticks to the store as they were bought in the beginning of the Nov at 1/3 of the current price.

My PVV532G640C32K kit is 16GB double-side.

Let's see, maybe there's another part to this story, like the SPD programming that was also first speculated about. But the fact remains, some of these Patriot kits are causing problems for a bunch of people with Core Ultra. We may or may not have the final explanation for it, but we can already get the word out there, so other people don't replace their board and CPU in vain, for example.

DDR5-7200 at 1.1V is crazy, but CL58 is also crazy high. That's similar latency to DDR5-6000 CL48.

We ordered a notebook for my friend with a Core Ultra 7 155H, I was surprised about the RAM, it has 16GB LPDDR5X-7467, soldered onto the board.

Please also post in the ASUS forum, maybe link this thread, so people understand there is not much to do right now, other than to replace the kit with a different one. Whatever they try about the board or CPU has a low chance of resolving it, from all we know so far.

More than likely, here it's about wrong SPD info (Patriot's fault) or Intel buggy firmware.
This issue is present on any motherboard, so it cannot be MSI, ASUS and Gigabyte fault.

The latest Low Power DDR5 chips run easy above 8000MT/s.
But these new native 7200 chips with 1.40V can reach 10,000MT/s !!!

Soy el segundo caso de este tema: ASUS Rog Strix Z-890-A sin POST después de VRAM QLED
Me pregunto si alguien consiguió algún reemplazo de Patriot. No puedo devolver mis palos a la tienda porque los compré a principios de noviembre a un tercio del precio actual.

Mi kit PVV532G640C32K es de 16 GB de doble cara.

Gracias por la información sobre el problema de compatibilidad con la serie Intel 800. He elegido la segunda opción: un servicio de reemplazo RMA del fabricante .

 

[Paupardo815ca02e9]

Hi everyone, I wanted to provide an update on my situation. Patriot eventually reached out to me and sent a new kit of Viper Elite 5 Ultra memory. I’m happy to report that these are fully compatible with the Z890 and are working perfectly.
Although the process took a bit of time due to the current situation, it was replaced at no cost to me. I’m really pleased with their response and glad they provided a genuine solution to the issue.

English please?

edit: Thanks for editing it to English. Sounds like a good ending.

we all cant figure it out so its not our fault....Right....
yet you have direct contact with intel and patriot. so get to work

ok . and msi can still likely see this. shills for msi is getting old. another msi blunder taking forever to get fixed.

shill excuses for msi is getting old.

I was just stating facts. I am not making excuses. You were barking up the wrong tree. Now you are already up to personal attack. This was the first one that I pulled you up about but had not yet articulated:

so get to work

I haven't looked the forum policy of this board but typically they frown upon personal attacks.

Lol saying there are shills in here is a personal attack? Good one. If I said the sky was blue you probably would be offended and take it personally. notice i said shills with an s

Non taken. But you were replying to me and it was directed at me as a personal attack. I was not defending MSI I was simply explaining the goal and scope of this forum.

Diverting attention.

notice i said shills with an s

You wrote shill and not shills:

shill excuses for msi

This seems just another way of diverting attention. When you initially replied to me you wrote shill. Now all of a sudden you say you wrote shills with an s. What are you trying to say here? You wrote plural where you actually wrote singular? That is not correct. Is there a different way of spelling shill? I have no clue what you are trying to say here. Explain it to me?

All I see is a lot of noise trying to divert attention. From what actually?

have you ever once was or is?

Bandit- if Patriot replaced the memory and the system works. Why do you want to blame MSI? Seems like an issue with the memory.

 

[citay]

This is not some MSI issue they are taking their sweet time to solve, it's a platform-wide issue with certain RAM kits. This should've been clear right from the first post.
