What is the best Lga1200 cpu for this board? 8 cores max? I read that all proccessors to this board only handle 3200? I then must overclock to reach higher speed? Which is the best cpu for that? I now have G.SKILL Trident Z Royal Series (Intel XMP) DDR4 RAM 32GB (2x16GB) 4000MT/s CL18-22-22-42 1.40V Desktop Computer Memory UDIMM - Silver (F4-4000C18D-32GTRS).
 
Hello again. As for the CPU, the top of the range Lga 1200 compatible CPU is likely the Rocket Lake 11900K(f) which is an 8 core 16 thread CPU, the 11700K(f) is also an 8 core/16 thread CPU but with lower Turbo boost speeds. As for memory, XMP should work whatever the speeds.
 
i like the 10 core 10900k but that´s your choice if ya need more cores.

and this is from product page\everything over 3200mhz is overclock
2x DDR4 DIMM, dual PC4-44800U/DDR4-5600 (OC), max. 64GB (UDIMM)

this mainboard is made for overclocking with 2 dimm slots

Yeah, the only reason I went 11 series was for PCI-E 4.
 
never thought about that thx Tatty.
10900k 16 x pcie 3.0
11900k 20 x pcie 4.0
 
I only got a Intel Core i5 11400F @ 2.60GHz. Rocket Lake 14nm Technology. It only can take 3200 and the memorys 4000mhz. It may be dangerous for a unclock able processor to overclock? Maybe a little? It surprises me that this board cannot take more memory then 64 and no more then 8 cores, when it is a extreme overclocking board, but to be fair 64gb or 8 cores it is not little.

In regards to your memory, have you tried selecting memory Gear 2 in the Bios and then selecting xmp for the memory to see if that might work? It only supports 64 because it's a fairly specific overclocking board and having lots of memory don't tend to overclock so well. If you go i9 or i7 you will need some fairly beefy cooling, you may be better to just get a 11600K(f).

In terms of overclocking, you have a locked multiplier CPU but you can increase the BClock from 100mhz to 102.5 but it has to be less than 103 otherwise it will crash. Your CPU Turbo boosts to 4400mhz on a multiplier of 44 so that BClock increase would give you around 100Mhz extra on both the stock speed and Turbo boost.

Thanks for the information. I will look at gear 2. I guess that takes a little extra cooling to change from 100 to 102,5. Thanks again for the information. It is in value for me. I am new to this with overclocking. Does a raise to 102,5 increase cpu life time much?

Is there also much difference in proccessor functions between mine and i7 or i9? I guess that this board cannot have a Xeon?

Not really, that is considered very mild overclocking, if your CPU voltage is on auto then it may adjust slightly, check before and after, it shouldn't cause much of a heat increase but if it does and your cooler is not up to it then you could try a small negative offset for the voltage.

Just saw you had just edited your post ........................ Not sure about a Xeon but an i7 or i9 would be much faster in the K versions, higher base clock, much higher turbo speeds and more cores/threads, there is a reason why at release the core i9 was at least 3 times more expensive than your CPU :)
 
I will look into it. The most motherboards and cpu works like old computers so they turn off auto if it gets to much heat?

If set to auto the CPU will get what it thinks it needs, if your cpu temps get to Tjunction MAX then it will be thermally throttled but it's best to avoid that if possible, as I said, if it happens you can set a negative offset voltage in your Bios that basically forces the CPU to take a little less voltage than it thinks it needs because in some cases it thinks it needs more than it does.

In essence, if you were to stress test without the BClk increase to 102.5mhz and your temps are good, the BClk increase should not make a significant difference to temps, maybe up to 5 degrees roughly but you have to tweak and test.
 
I tried and got it to 2.66ghz with 3200mhz memory speed. I also believe i did set it to 102. The temps was OK. I bought a Noctua NH-D12L 120mm cooler in Aug. So the temps will be more OK now. I had a cheap Cooler master before.

I have ⚡ bolt 4 on this board. What can i use it for? To charge the phone or Chromebook?

This will explain it in far more detail than I could.

I changed back last time. But i tried again today. I changed BClk to 102,5 but it only shows 2.59ghz. Last time i got 2.66. It should be a unclock able cpu. Had i luck when i first tried?

I only got a Intel Core i5 11400F @ 2.60GHz. Rocket Lake 14nm Technology. It only can take 3200 and the memorys 4000mhz.

When i change to 102,5 it becomes 4202mhz and with 100 it becomes 4400mhz. It must be something wrong.

When i check bios with 102,5 it shows 2665mhz. In Windows 10 2.59ghz. But with 102,5 the Target Cpu gets 4202 and with 100 4400.

Firstly, it is the CPU's multiplier that is locked, not the BClock. Try 102 BClock and let me know what speed that gives you under load. Have you tried overclocking your memory? You should be able to on that board, there are loads of YouTube video's out there showing memory overclocks beyond 3200mhz on the 11400, have you tried the XMP profile? If that does not work, try manually dialling in 3600mhz in the Bios, initially leave timings on auto and make sure the voltage is set to ay least 1.35v and see how that goes, if it boots you can fine tweak later.

I will give it a try. I got the cpu to 2.66ghz at my first try last year with 102. I guess it was luck then? Now it do not seems to work anymore. Only 2.59ghz as standard in Windows 10. With boost 4.4. My cpu should handle 3200 memory speed at the most according to Intel.

That's the base spec that Intel guarantees but not what may be achievable with an overclock, for example ............... the Intel spec sheet for my 11900KF also says 3200Mhz, I can run my memory at 4500Mhz. Reminder that you may have to select Gear 2 mode in your Bios (motherboard may select automatically on boot) if you try running memory at XMP 4000Mhz.

Base clock does not really matter if you are getting max boost but if it does not boost beyond 4400Mhz then you may need to increase the power limit which should be doable, that should also be an option in your motherboard Bios. Your CPU is rated at 65w but you should be able to select upto 125w which with your new cooler should not be an issue.

More specifically the guaranteed-to-work speed is 3200CL22 @ 1.2V Vdimm, since that's the fastest DDR4 speed JEDEC supports.

Anything faster is technically overclocking and are not guaranteed or covered under warranty, including XMP modes. IMHO 3200C16 should be trivial, 3600C16 should still be pretty attainable, anything above is much harder to get stable results.

Always think of XMP modes as vendor-provided overclocking recommendations rather than something that will be 100% bulletproof (Hell even MS is saying how enabling XMP is major source of BSODs), because they are many factors at play like CPU/mobo/RAM/BIOS quality, temperatures and all sort of voltages when put together will put a practical limit to how fast your RAM can go.

Also I wouldn't bother with BCLK CPU overclocking, too little gains for the trouble.
 
The, Asrock motherboard is espcially built for overclocking so i guess it do not increase lifetime so much?
