Guys

Got my E6400 overclocked to 3.7Ghz using 463 fsb (iirc).

My IP35 boots and reports the processor as 3700mhz, however almost every application I use including cpuz/intel processor ID app all say it is running at the stock 2.3Ghz?

I know that the chip will throttle back, and have seen it sit around 2.7 before and crank up to 3.7 on full use.. it just seems like whatever I do in the bios doesn't matter, windows wants me running at stock speed.

please help, I hope I'm not being dumb!!

Yeah I'll go try turn it off just now, but throttling will not reduce it back to stock speeds though. IIRC its 63% default in my bios, which would take me to 2.33ghz when overclocked too 3.7 not back to stock 2.13. CPU-Z reports CPU at 1596.2mhz as I write this so thats throttling kicking in on stock speed.

So clearly somewhere between bios and windows I'm losing my overclock :( I'll take a video of the computer starting to show I'm not talking crap.
 
But I don't want too! :( Took me ages to run the chip in and eventially get it up to 3.7 from 3.6. Its worked fine for about 6 months like that too.

I will go test to see if it works, report back in a min.
 
When the computer posts, the abit bios displays my e6400 running at 3.7ghz. Windows and every other program under the sun shows clock speed at stock 2.13ghz.

Just dropped it down to 450fsb for 3.6Ghz, same problem again POST reports 3.6hz windows reports 2.13ghz.

wtf :confused:

faulty motherboard? chip finally fed up?

Edit:

450fsb x 8 = 3.6Ghz
Core V = 1.485v
DDR2 = 1.9v
North B = 1.37v

System is E4600 on Abit IP35 with 4Gb DDR2-667 and 8800 512 GTS. CPU temp stable around 47c.

I can't really do that as no matter what I put into the BIOS clock speed wise windows just reports 2.13.

I've went down - 3.7 > 3.6 > 3.5 > 3.4 > 3.3 > 3.2ghz one after the other and its still reporting 2.13ghz with cpu-z running prime.

I'm away to try below 3ghz
 
Ran tests with intel burn test, sandra and some others. all result in what appears to be stock performance and same times. re-loaded safe default in bios and started again to no avail.

wierd thing is windows 7 rc7200 32bit recognises the 3.7ghz in the system panel but cpu-z reports stock speed? :rolleyes:

I give in! :(
