Memory errors TUF GAMING B650-PLUS WIFI BIOS 1636

Level 8

processor Ryzen 7600x

so i i'm facing some memory errors, at first tried to get a another memory thats on the compability list a MEM DDR5 16GB 5200MHZ KINGSTON FURY BEAST KF552C40BB-16, i had before a MEM DDR5 32GB 6000MHZ CORSAIR (2X16GB) VENGEANCE RGB CMH32GX5M2E6000C36.

and it didnt worked, it would crash or not boot giving the red light,  the 2x16 memories not on the list would perform better even working for a while and then eventualy crash, so i tried different slots and so until i thought yeah lets puts every 3 memories on it and lets see what happens and its by far the most stable, for 2 days it worked perfectly, but then it crashed today 2 times, too soon to be happy, the system would not boot then after a while it got back, crashed after a while, got back and did not crash.

so idk what to do to stop those crashes, i've read someone on guru3d changed memory controller, and solved the problem but idk which option he did,  idk if that would solve the problem

tried clearing cmos and all etc

Did you buy those sticks individually? Disable EXPO, and see if the behaviour is replicable.

13900KS / 8000 CAS36 / ROG APEX Z790 / ROG TUF RTX 4090

this one was bought as a kit

this one is just a single memory i bought

forgot to say that expo is disabled the 3 memories seems to run at 48000mhz

I think you bought the wrong one, this one is for Intel support. For AMD EXPO Support at Kingston, there must be an E in the designation after the BB.

You have this: (

But need this one: (

AMD Ryzen 9 7950X3D | ROG CROSSHAIR X670E EXTREME | ASUS TUF Gaming GeForce RTX 4090 OC | G.Skill F5-6000J3040G32GX2-TZ5N | WD Black SN850X | PHANTEKS Glacier One 360 T30 Gen2 | LG OLED42C27LA | Phanteks NV7 | Seasonic PRIME-TX-1300

sigh... you are right, but would that cause memory errors if i'm not using expo?

sorry by the late reply, i checked the compatibility list available by asus, all memories the kit (2x16 corsair CMH32GX5M2E6000C36.) and the single memory (1x16 kingston KF552C40BB-16) are in the compatibility list.
The corsair memories while have frequency of 6000mhz, ryzen 7600x should run it with expo, i tried and its very unstable, with expo disabled it runs at 4800mhz with less unstability but still bad.
The kingston memory runs at 5200 mhz while there's no expo support it should work fine, by the compatibility list.
Using 3 memories while more stable its not optimal and sometimes would run in a vicious cycle of crashes and reset.
I feel conflicted to buy more/other memories in the compatibility list and have the same behaviour, i guess i should wait and pray for bios update.

Hi. with 7700x and kingston fury beast memory.  Only with the last BIOS I had no BSOD or ram error with memtest and EXPO 6000 or 5600 enabled (with 0.05 overvolt), but playing Forza Horizon 5 I had a lot of crashes. Falling back to 4800 everything is fine. Today I replaced the MB with a MSI MAG x670e tomahawk. Last BIOS, no error ingame with EXPO 6000. The strange thing is, ok that external temperature are a little lower now, but CPU temperature are 15-20° lower. Also When I played at 8.00 AM and it was fresh, CPU temp where always around 82-85. Now maximum was 72. The AiO is the same and also the thermal paste (replaced after 3 months) was putted at the same way

i updated to the new bios updated released yesterday 1654, but results are about the same over here. Did tests with with each memory, in dual and all 3. I think the update did not change stuff in regards to memory stability.

Level 8

For me, the latest bios 1654 is the by far most unstable version. System won't even launch on every stetting. With or without Expo, BSOD, Win koading-errors, system restore, etc... Even bios will crash. Have to go back to 1616. Install, works like charm.
