ok thank you both i wil try it today. i have one more problem. i installed an i5 - 11600k with a raijintek CPU Cooler Leto Pro RGB and in bios when asked i choosed tower cooler. When i run any benchmark (cinebench or prime95) the cpu temp hit 100 and i am stopping the test. Should i check if screws of cooler is tight enough or change the bios setting to box cooler? I saw that this setting affect the cpu voltage.
Yeah, the Rocket Lake CPUs get seriously hot, due to the increased power consumption. Did you use thermal paste according to the instructions? I tend to put a vertical line of thermal paste over the CPU, that always leads to a good spread. All the screws need to be fully screwed in. If you didn't tighten them all the way, you did it wrong. They have a size so that the cooler applies exactly the correct pressure onto the CPU when they're all fully tightened.
So, first order of the day, tighten all the screws until the end. Second, update the BIOS, really important.
This can drastically reduce power consumption under load, by reducing the added VCore that MSI likes to apply to be stable under all circumstances with all CPUs. Using this option, you can reduce the additional voltage if it's not needed for your particular CPU, and you do this by stability-testing lower settings. Most CPUs do not need the added VCore from MSI and run just as stable with a lower "CPU Lite Load" setting. This way, i saved 55W of pure CPU power consumption under full AVX load, which reduced temps by 20-30°C. This is a tremendous result. See above thread for further details.
There's a chance it's installed correctly, but your statements about tightening the screws suggest to me that you maybe haven't tightened them all the way. This would be definitely wrong. They are machined so that you can't overtighten them, but for the right pressure, you need to tighten them until you can't anymore. Also, you need a decent amount of heatpaste between CPU and cooler base.
For the rest (BIOS update, CPU Lite Load setting) see above.
Oh, so you have an older graphics card that didn't come with a GOP (Graphics Output Protocol driver). Before GOP, they used to use VBIOS (Video BIOS), because Windows 7 was not compatible with GOP. To get rid of that message, you might have to set the BIOS to CSM, but then you have a problem when you want to boot from an M.2 NVME SSD, because i think that only works in UEFI mode. So it's best to just ignore the message if you can still boot fine in UEFI mode.
ok so with tower setting for cooler and your guide about lite load i tested the modes with cinebench r23
mode 9 (auto) - 10642 score - max temp 91
mode 5 - 10623 score - max temp 86
mode 3 - 10564 score - max temp 81 (preferred mode)
i couldn't go lower , the pc was freezing.
about GOP before the update i could enter bios with uefi with no problem, do you mean that in latest bios they change the support of older graphics cards?
Nice. Did you test CPU Lite Load mode 3 with Linpack Xtreme, like i said in the thread i linked? It has to say PASS there. If the PC is freezing, it could already be unstable at mode 4 without you knowing.
Also, once you find a Linpack-stable setting, i would go one level higher again, so you have a bit of headroom. For example, when mode 3 is confirmed stable, i would set mode 4. This way, you're not right at the edge of stability.
About the GOP message, either you had some different setting before, or they changed something in the BIOS, can't say from here.
