P4EE L3 Cache?

[bodhammer]

I have a P4EE 3.4Ghz Gallatin (http://processorfinder.intel.c...ils.aspx?sSpec=SL7CH) on an Epox EP-PCA3+ (875P) motherboard. Using CPU-Z 1.47, sometimes I see 1MB of L3 cache and sometimes I see 2MB. I have the core voltage on the motherboard set at 1.575 as per the VID on the web page above. I am able to run the chip steady up to about 3.6GHz with a Zalman CNPS7000A-Cu but I leave it at 3.5Ghz (207Mhz FSB). PAT is on 2GB memory at 2-3-3-5. I don't see any crashes in any benchmarks and everything is running steady.

CPU-Z shows core voltage at 1.568V

What could be causing the anomaly on the L3 Cache?

Thanks,
Bod

Lol, that is strange.

Seems more like a typo on Intel's site that CPUz somehow copied. No desktop/consumer-level Pentium 4 CPUs ever had a Level 3 cache; only L1 and L2.

No, the Galitin core P4 extreme edition DOES have L3 cache. As to the annomoly, not sure.

These do:

"Gallatin's 2MB of L3 cache is the primary difference between Gallatin and Northwood. This extra cache allows the processor to keep more data readily available and improves performance compared to a standard 3.4GHz Pentium 4. Cache, however, is expensive, making the P4 EE one of Intel's most expensive processors. "

I tried playing with the motherboard CPU Core voltage and I got it up above 1.6V but CPU-Z never reports a core voltage that changes from 1.568V so I backed it off.

Gallitin Pentium 4's Had 2MB of L3 cache.

They rebadged a Xeon into a Pentium 4 Emergency Edition.
