These extreme processors (QX6800) should all be 130W TDP, sent a message to get this corrected.
Check the datasheet on http://www.intel.com/design/processor/datashts/316852.htm
Section 5, table 24
Thank you for your reply, tmsimmon.
After I posted I did find this http://www.intel.com/support/processors/sb/CS-028846.htm :
What's the difference between Max TDP and Stepping TDP?
For processors, the TDP will sometimes vary depending on the stepping of the processor. The Max TDP is the highest TDP value of all the steppings. Stepping TDP is the TDP for that particular stepping of the processor.
Tsimmon, unless you work(ed) for Intel, I will likely go with the reply I got from intel via chat (slightly edited):
Intel: Hello. Thank you for using the Intel Customer Support chat service. We are glad to be of service. How can I help you today?
dyeager: I posted this question to the processor forum but got no response:
If you look at this web page http://ark.intel.com/Product.aspx?id=30720 and choose this heading: ************* ORDERING AND SPEC INFORMATION Retired & Discontinued Boxed Intel® Core™2 Extreme Processor QX6800 (8M Cache, 2.93 GHz, 1066 MHz FSB) LGA775 Socket Step Step TDP Ordering Code SPEC Code Halogen Free VT-x LGA775 G0 100 Watts BX80562QX6800 SLACP No Yes LGA775 B3 130 Watts BX80562QX6800 SL9UK No Yes LGA775 B3 100 Watts BX8056QX6800 SL9UK No Yes Intel® Core™2 Extreme Processor QX6800 (8M Cache, 2.93 GHz, 1066 MHz FSB) LGA775, Tray Socket Step Step TDP Ordering Code SPEC Code Halogen Free VT-x LGA775 G0 130 Watts HH80562XH0778M SLACP No Yes LGA775 B3 130 Watts HH80562PH0778M SL9UK No Yes **************** You will notice that the TDP for SPEC code SLACP has a thermal of 100 watts if boxed, 130 if trayed. Any way that you can tell the difference on the TDP from just a photo of the chip? Any way to tell given a processor identification utility ( ie, is the TDP info readable inside the chip without a SPEC code lookup table?) Otherwise, what is the TDP of any QX6800 if you do not overclock? (I presume headroom is added to the TDP for overclocking) Thanks
Intel: Let me check. Thank you for waiting. The TPD information is not printed on the processor.
dyeager: Any codes that would indicated whether it was trayed or retail?
Intel: No, since the retail boxed units come on a retail boxed, we can only determine that by the FPO batch number.
dyeager: Any utility that will tell you/confirm what the TDP is of that particular chip? ie 100 or 130?
Intel: We do offer the Intel(R) processor Identification utility, however this software won't tell you the TPD information, you may get is using a 3rd party application.
dyeager: OK, then the last option. Is there TDP headroom built in to these extreme processors assuming that they will be overclocked. i.e.: would a Qx6800 with a TDP of 130 actually only use 100 in a system that does not support overclocking?
Intel: I am afraid not, there is no TPD headroom.
dyeager: The 100 TDP show on the above webpage for the retail boxed processor is correct, right? I mean it is not a typo, right? Thanks.
Intel: That is correct
dyeager: I will make certain that I get a box. Thanks for your time.
Intel: Thank you for using chat. We value your suggestions and would appreciate it if you would take a moment to complete our survey. The survey will appear when you click "Close'' to close the chat window. Have a nice day.
P.S.: After a few days of no replies, I will give out points. Thanks for your help.
I will give it a week to see if the stepping TDP changes from 100 to 130 on the Ordering/Sspecs/Steppings page of http://ark.intel.com/Product.aspx?id=30720. The maximum TDP for the QX6800 was and is 130. Thanks for your help.
If you are correct, then QX6700 may also need to be changed
