Hi,

I've been experiencing some issues with my RAM. Enabling XMP seems to cause problems, and I keep failing Test 8 with Memtest86. However, when I run Memtest86 without XMP enabled, it passes successfully. I conducted individual tests with a single stick in slots A2 and B2 with XMP enabled. Stick 1 passed in both A2 and B2, while Stick 2 passed in A2 but failed in B2. I reran the tests several times and obtained the same results. Initially, I suspected an issue with the B2 slot on my motherboard, but since Stick 1 passed in B2, that seems unlikely.

System Details:

Motherboard: Asus ROG STRIX Z790-E GAMING WIFI 2 (BIOS Version 1202)

Case: Corsair 7000D Airflow

PSU: Corsair RM1000x

CPU: Intel i9-13900K

GPU: GIGABYTE 4070 Ti Super

RAM: Corsair Vengeance 32GB

Storage: Samsung 990 Pro 2 TB

I'm at a loss about what to do next. I'm considering an RMA for the RAM, but I'm not sure if anyone else has encountered similar issues. The RAM kit I have is Corsair Vengeance 32GB (SN CMH32GX5M2E6000C36), and I have checked my motherboard QVL, and it shows it as listed.

If you're correct with BIOS revision 1202 the current version is 2202 which is around 8 revisions newer, probably worth flashing that before returning anything and doing some further testing. Early BIOS revisions are often unstable and QVLs typically relate to the latest BIOS revision for the motherboard. If it was just a typo and you're already on 2202 feel free to ignore this :)

What Ixion said, and assuming you are only using 2 DDR5 ram modules, in A1 & B2 as outlined in the manual... once you have updated to latest bios, you "should" be more stable. I had similar issues as well... mine mainly were down to me not reading things right, and had 4 modules, and tried to enable XMPII which caused me all sorts of issues!

Double check the specs of the exact model of ram, and compare the timings to what your bios XMPII timings, voltages etc are!

I also tried to set my  Memory Controller Voltage to1.35 which seemed to work at first but then I was unstable again.

Your RAM is rated for 6000 at CL40 at 1.35v. Since it's unstable at these specs, you'll need to go for ~ 1.375 volts. Just make sure to stay under 1.4v.

Ok are you saying to try to set my Memory Controller Voltage to 1.375 volts and see if that works? If that is the case I will try running Memtest86 again since that is the best way for me to make sure my RAM is stable.

A lot of Intel 13th and 14th Gen CPUs are currently having stability issues which is why Intel had to add that Baseline settings. It could well be that your CPU is causing the trouble and the memory kit and the board may be fine. Hard to say.

Still, you can try increasing these voltages slightly:

  • Dram VDD voltage

  • Dram VDDQ voltage

  • CPU System Agent voltage

  • IVR Transmitter VDDQ voltage

  • Memory Controller voltage

You don't want to go too overboard though.

Looks like Asus just released a new BIOS to throttle back the automatic overclock of 13th/14th gen processors which was causing reported stability problems (1301) I can only think I got linked to the wrong motherboard before!

Interesting that your spd speed rating on the DIMMS is Cas 40, I guess that's a different XMP profile or lower voltage. If you're still struggling with stability you could try using the SPD ratings rather than the XMP and back things off a little, you probably won't notice the difference as the clock speed makes a lot more difference than the latency.

Hey, So Memtest86 passed runs 1 and 2 but failed runs 3 and 4, indicating it's still unstable with BIOS version 1301. I also reverted to version 1201 because 1301 caused my CPU multipliers to fluctuate erratically, jumping from 55 to 8 on cores 1-9 and from 43 to 8 on cores 10-24. This erratic behavior seemed unusual and might be related to the Intel default settings. After reverting to version 1201, this issue stopped.


I might just keep my RAM at the baseline 4800 MHz for now and wait for any new BIOS updates that might fix the issue, or I might consider buying new RAM. When I had XMP enabled, I didn't notice a significant difference between 4800 MHz and 6000 MHz, especially since I usually game at 60 FPS in 1440p, so I'm not sure how much 6000 MHz would benefit me.

Try XMP with a single DIMM, then swap and try with the other DIMM, if both those pass tests, try the other two DIMM sockets on the motherboard for dual channel. If that still fails, try putting them into slots next to each other so they run in single channel and test.  That's a fast way to check if it's a DIMM, socket or motherboard.

So I have tried that before. When I had a single ram in A2 it passed with both but within B2 with a single ram, ram stick 1 was passing but ram stick 2 was failing.

There's no reason you shouldn't be able to run that board at 6000MT/s unless you've got a particularly terrible IMC on the CPU. Increase the VDD and VDDQ on the mem to 1.4 manually and see what happens

I tried that and it didn't work

Go 1.45 (it's safe, don't worry)

 

If not then I'd say your CPU's IMC is just ###### and can't support the faster than JEDEC speeds. If the RAM works at the stock 4800 then I doubt it's that. If you can get a hold of someone else's sticks to test that might be a good idea. Or go single stick and see what happens, that should be kinder on the IMC as well

Ya I have ran Memtest86 with XMP off with base 4800 it passes all 4 runs. When I set the Memory Controller to 1.35v and DRAM VDD/VDDQ 1.4V  Memtest86 will pass runs 1-2 but fail runs 3-4. Also to note it fails mainly on Test 8 ( random number sequence)

Also I did Test running single ram with XMP on

If one was passing and the other failing then yeah, sounds like possibly a dodgy stick. Just RMA it and get another kit, hopefully no issues with that one!

I have a open ticket right now with Corsair and I think I might just RMA the ram and see if it was Stick two that was the issue. But Like I said Stick 2 Passed in A2 but failed in B2 which was super odd lol.

    • Newegg offers insane combo deal on Amazon Prime Day 2026 that beats Steam Machine

      By sphbecker · Posted

      Sadly "beats Steam Machine" isn't much of a brag.
    • An oversimplified explanations of Passkeys

      By +Warwagon · Posted

      Passkeys: Think of them like a broken heart necklace. Imagine one of those heart necklaces that breaks into two matching pieces. One person keeps one half, and the other person keeps the other half. With passkeys, the website has one half, and you have the other half. If the website gets hacked and someone steals its half, that stolen piece is useless by itself. It cannot unlock your account without your matching half. This particular heart necklace is one of a kind, there is only one in existence. Your half of the necklace has to be stored somewhere. It might be stored on your phone, tablet, computer, security key, or a password manager that can sync it between all your devices. A security key is a small physical device that you keep with you, kind of like a house key, car key, or flash drive. I would not usually recommend a security key as the first option for the average person. For most people, it is easier to use their phone, computer, or a password manager that can sync passkeys between their devices. A security key is more like a spare key you keep in a safe place, just in case you lose access to your other devices or your password manager. Some security keys plug into your computer. Some plug into your phone or tablet. Some get tapped against your device. The idea is simple: a security key can hold another passkey for the same website. Think of it like creating a second one-of-a-kind heart necklace for the same account. One necklace could be paired with your password manager, while another necklace could be paired with your security key. That means the website has more than one matching half on file. One half matches the passkey in your password manager. Another half matches the passkey stored on your security key. So, if you lose access to your phone, computer, or password manager, you would still be able to log in using the passkey stored on your security key. Think of it like keeping an extra special necklace piece on a tiny keychain, stored somewhere safe. The website still has the matching half for that security key, but your half is safely stored inside the little key. A passkey does not automatically exist on every device you own. It lives wherever you save it. If your half is stored on one device, then that device is the one that has the matching piece. For example, if you create the passkey on your Windows computer and it is only saved to that computer, your iPhone does not automatically have that same half. If you create it on your iPhone and it only stays on that iPhone, your Android phone does not automatically have it either. That is where password managers come in. A password manager can act like a protected jewelry box for your passkeys. Instead of your half of the necklace being locked to only one device, the password manager can securely sync that half to your other approved devices. For example, Apple Passwords and iCloud Keychain can sync passkeys between your Apple devices. Google Password Manager can sync passkeys with your Google account. But password managers such as 1Password and Bitwarden can sync passkeys between everything, your phones, tablets and computers. Now, you might ask: “What happens if I lose access to the device that has my passkey?” That depends on where your passkey was saved and what recovery options the website gives you. If your passkey was synced through a password manager, you may be able to sign in from another device that has access to that same password manager. For example, if your passkey is saved in iCloud Keychain, Google Password Manager, 1Password, or Bitwarden, another approved device may still have access to it. If your passkey was saved only on one phone, computer, or security key, and you lose that device, then you may not have your half of the necklace anymore. In that case, you would usually need to use the website’s backup login or account recovery options. A lot of websites that support passkeys still let you fall back to your regular password. So if you lose access to your passkey, the site may still let you log in with your password, a code sent to your email, a text message, a recovery code, or some other account recovery process. That is convenient, but it is also important to understand: if the website still allows password login, then your password still matters. Passkeys are safer than passwords, but if your account still has a password as a backup, you should still use a strong, unique password and turn on two-factor authentication if the website offers it. This is why it is a good idea to have more than one safe way back into important accounts. For example, you might keep your passkey in a syncing password manager, add a second trusted device, save recovery codes somewhere safe, or set up a backup security key. A passkey is very secure, but just like a real key, you need a backup plan in case you lose access to it. Now, you might ask: “What stops a hacker from copying my half of the necklace?” That’s the important part: your half is protected. It is not something you type in, and it is not something the website gets to keep. Think of your half as being locked inside a tiny safe on your phone, computer, security key, or password manager. That safe only opens when you approve it with your fingerprint, face, PIN, or device password. When you log in, the website does not need to see your half. It only needs proof that your half matches its half. Your actual half is not handed over to the website. This is different from a password. With a password, you type the secret into the website. If you type it into a fake website, the hacker now has it. With a passkey, you are not typing your secret into the website. Your device is proving you have the matching half without giving the half away. That also helps protect you from fake websites. If someone makes a fake login page that looks like the real site, your device can tell it is not the real match. It will not use your passkey there. Now, could someone use your passkey if they stole your device, got into your password manager, or somehow unlocked the safe that holds your half? Yes, that is why your device password, PIN, fingerprint, face unlock, and password manager security still matter. But a hacker cannot just steal your passkey from the website or trick you into typing it into a fake page like they can with a password. That is why passkeys are safer than passwords. The two matching pieces have to come together, like two lovebirds who were once separated and are finally reunited.

      I heard from a lot of people that driver support for the latest games when RDNA first came out (Radeon 5000 series) was pretty bad, but if you didn't buy the card on day one, or were not trying to play the latest titles, then you were isolated from that issue. Other than that, it's been good and only getting better.
    • Meta launches new AI glasses in 26 styles and Muse Spark multimodal capabilties

      By pradeepviswav · Posted

      Meta launches new AI glasses in 26 styles and Muse Spark multimodal capabilties by Pradeep Viswanathan Meta today announced a new line of Meta Glasses in partnership with EssilorLuxottica. The new AI glasses build on the company’s existing smart glasses portfolio, which is sold under the Ray-Ban Meta and Oakley Meta brands. The new Meta Glasses start at just $299, are compatible with prescription lenses, and will be available in 26 styles across different colors, lenses, and frames. At launch, Meta Glasses will be available in three frame styles. The Meta Adventurer features a clean rectangular design and comes in Standard and Large sizes. The Meta Fury is a bolder frame for users who want a stronger look. Meta Glasses by Kylie is a slim oval frame designed in collaboration with Kylie Jenner. Similar to existing Meta AI Glasses, the new Meta Glasses include a dedicated action button that can be used to quickly access Meta AI or launch a favorite feature. They also feature open-ear speakers for calls, music, and more. Meta has also included a multi-mic array with wind noise reduction for calls and messaging. Users can capture photos and videos hands-free using voice commands. Meta claims more than eight hours of battery life, while the portable charging case can provide up to 40 additional hours.
