QX6800 different TDP for same SPEC code - how do you tell the difference?

idata — Thu, 16 Sep 2010 00:12:38 GMT

If you look at this web page http://ark.intel.com/Product.aspx?id=30720 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 tell the difference on the TDP from just a photo of the chip? Any way to tell given a processor identifcation 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

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 http://www.intel.com/design/processor/datashts/316852.htm

Section 5, table 24

Thank you!

Thank you for your reply, tmsimmon.

After I posted I did find this http://www.intel.com/support/processors/sb/CS-028846.htm 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?

mailto:dave-yeager@columbus.rr.com dyeager: I posted this question to the processor forum but got no response:

Intel: Let me check. Thank you for waiting. The TPD information is not printed on the processor.

mailto:dave-yeager@columbus.rr.com 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.

mailto:dave-yeager@columbus.rr.com 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.

mailto:dave-yeager@columbus.rr.com 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.

Check the TDP in ARK using the SL Code... they all show 130 W.

The tool takes a day or two to refelect the edits. Datasheet is also correct.

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 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

TIM_S_Intel — Fri, 24 Sep 2010 15:20:47 GMT

Yes, it's disappointing to see these mistakes!

I did submit feedback to get this all corrected to match the datasheets... (Section 5, table 26)

When in doubt... the datasheet is where you go.

It took along time (I checked back every few months), but intel did correct the info to 130 watts, thus tmsimmon was correct and awarded full points.
