Bought a socket 478 3.4GHz Intel SL7CH from ebay and the CPUID V1.53 program says that there is no L3 cache. I was expecting 2MB. Should I put the 3.2GHz with 1MB of L2 cache back in or leave the faster one with only 512KB of L2 cache in?

I should add that my Intel D865GLC motherboard is listed as compatible with the 2MB L3 processors that Intel produced. The chipsets and BIOS are all the latest available. I'll have to check it on the other two 865 boards I have running to see if it is a motherboard issue instead of a lame processor.

Does CPUID show it as SL7CH with Gallatin core? my SL7CH shows the L3 cache in CPUID as well as it showing up in the BIOS. The BIOS gives me the option to enable/disable it... so maybe check there as well and make sure its enabled. good luck.

The L3 cache should show up in CPU-Z unless the CPU is defective or the BIOS is somehow set to disable the L3 cache. I have the Xeon version of the 3.2 Gallatin (SL7AE) and the 2 MB of L3 cache showed up immediately after I installed the CPUs in my board. I'd check the BIOS first and then suspect the CPU. I wouldn't be terribly surprised if the CPU is a dud since it is an Extreme Edition CPU bought off eBay and may be counterfeit/misrepresented (such as a normal 3.4 GHz P4C being sold as a 3.4 EE) or has been abused by some overclocker in the past.

Does your chip look like this?
