Hi guys, got a strange issue here.

Got an overclock going on the i7 950 upto 3.8Ghz.

The bios reports it at this speed, so does CPU-Z.

Unfortunately, Windows itself and Everest have different ideas.

Any idea what's going on here? Strange one.

Speedstep and Turbo are disabled btw.

Have you refreshed the rating in windows?

This kind of thing happens all the time. I've seen misreported clock speeds in Windows going back to the socket 370 days.

If CPU-Z is saying it's at the right speed go with that. Windows says my ancient core 2 duo system is running at 4.5ghz. CPU-Z and the bios say otherwise.

Yeah, that's the first thing I did actually.

It's like the x24 multi throws it off.

Happens to me all the time but for me it's usually CPU-Z that reports it wrong.

windows is wrong. If you doubt it, do some math... BCLK x multi = speed

Ok. Now I see why people hate the x24 multi. Prime95 run failed over night. lol Oh well.

always use odd multipliers.

Also, don't use prime95, use LinX.

I passed 20 runs in Linx.

Got a feeling what happened, was that the Anti-Virus started doing weird stuff whilst Prime95 was running.

do 200 with max memory.

Windows and Everest are wrong. MS is stupid enough to figure out overclocked speed and everest is garbage.

Will do that overnight I think.

CPUID is a fixed stamp Intel puts on every processor, it's a command that makes the CPU reveal it's STOCK, sold as model number and stock sold as clock speed. This is a FIXED function ID code, it never changes regardless of what you manually set the clocks to.

Sensor reads are what programs like CPUz and other programs that actually query the sensor, not the CPUs fixed function ID code. Some programs read sensors, others read CPUID. CPUID code is NOT to be confused with the program by the same name, that program does BOTH, reads the CPUID, then reads the sensor to confirm the CPUID.

Windows failure to read proper bus speeds is the cause for the clocks to be wrong at the end. Windows has always had that problem, something to do with CPUID itself causing the bug and it never being fixed.
