HP DX2300 45nm CPU unlock

[DeathBringer]

Have you any Pentium E5x00 or Celeron E3x00?
Do you know any motherboard based on 946GZ with official support of 45-nm CPU?

I just pulled a Pentium E5300 (SLGTL) from my scrap bin. Just tested it to be good. I do not know of any 946gz boards that support a 45nm cpu. I do have a Intel DQ45CB board that supports 45nm and 65nm cpus, but not Pentium D or Pentium 4 cpus. Kinda thinking it would be easier to have a newer board support older cpus.

Try to boot with it on this motherboard.

I just tried and it does not work. No bios beep codes or display. Only gets a little bit warmer than room temp.

So BIOS patch will not help.

To xsparexstewx:
Are you checked this patched bios ?

I have an e6700 from another system's upgrade

SamirD, can you test modified bios. Update with Bootblock for pass of Wolfdale cpu core.

Good  day! I test this bios, computer start  correctly, but  cache size  in bios is 0kb.  I  test E5300 and E7500 CPU.
UPD. E7500  working at  1600 MHz.

Hi, I flashed the modified bios from this post and board successfully started with C2D E7500 and also with Pentium E6500, but there is one problem - the frequency multiplier is stuck at x6 value, which causes the CPU not working at full speed. Is there any way to fix the multiplier at the bios level? I attach the CPU-Z txt report if it helps somehow.
