How to solve the problem with the number of processor cores?

Question

Iron

Good afternoon!
I recently assembled a system on socket 1156, on a Xeon X3440 and with an ASUS P7H55-M motherboard. The mother, which is a pity, came from China without radiators on the power circuits, which is sad, but most likely it does not matter.
After checking the performance in the CPU Queen, I realized that something was wrong somewhere - the CPU scored 21000 points, and judging by the tests, it should be about 28000. For
some reason, suspicions immediately fell on the number of cores. With the help of msconfig, I found out that yes, only 2 cores are working. I set 4 (here is the first question - should I set the number of threads or the cores themselves?)
Rebooted. The test result is about 22000, which is probably an error.
After making sure that Windows itself sees everything correctly, I went to the BIOS.
Here in the "Enabled Cores" item, I noticed that you can set only 3 options - "All", "1" and "2". The second question is, is it supposed to be like this?
PS if anything, I have Windows 7, 32bit (upgrade to 64bit).

Answer 1

In general, I write what I did and how it worked.
Firstly, I checked the msconfig file, where, as it turned out, it seems like you need to uncheck the "Number of processors" box.
Secondly, I played around with the BIOS settings, in the CPU Configuration tab. Rebooting Hyper Threading helped me. The "Enabled Cores" parameter, apparently, did not mean the number of cores itself, but something else, because when all 8 threads started working, the maximum parameter still remained 2. Perhaps loading the recommended parameters will help you.
I did not update the BIOS, but as Ezhyg advised, it's worth a try just in case

Answer 2

This motherboard does not support this processor.

The only thing I can advise is to change the motherboard and select a new one with support for your processor.

Answer 3

All those who say that the mother does not have the support of the mother, etc. etc. - Go smoke materiel, please.
Through a long search for a bug, due to which only 1 core was loaded, the following was found out. Owners of ASUS motherboards SHOULD disable jmicron! This controller conflicts with the video card and because of this, friezes, lags, etc. begin.
