222101 - Drove home and returned delivering c22 to Fry's Service Department.
222102 -
222103 - On arrival in Service Department, Ken was at another location in the
222104 - store. Fernando called him. He said that Ken's workload suddenly
222105 - increased. He will call later today, when he can do the work on c22.

2229 -
222901 - Ken called. He needs password to access the desktop.
222902 -
222903 - Ken has examined the BIOS and reports only 5 degree c difference
222904 - between processor #1 and 2.

222907 - ..

2233 -
223301 - Arrived at Fry's. Ken was busy helping a customer at the Service
223302 - counter.
223304 - ..
223305 - He motioned to check c22 setup on a workbench.
223307 - ..
223308 - The BIOS was on the screen, and showed only 5 degree difference
223309 - between the 2 processors. This conflicts with the record, of 20
223310 - degrees differential reported in the letter to Warner at Intel
223311 - submitted on 160329 1902, ref SDS 36 X69T, and citing snapshots of
223312 - the BIOS taken yesterday on 160329...
223313 -
223314 -
223315 -
223316 -
223318 - ..
223319 - After Ken finished with the customer, assisted him accessing c22 OS.
223321 - ..
223322 - We opened Windows 10 Enterprise on c22 dual boot system.
223324 - ..
223325 - Initially, Core Temp does not show 20 degree difference between cores
223326 - for processor #1 and 2; rather Core Temp showed only a 10 degree
223327 - difference like the BIOS, per above. ref SDS 0 AC5M
223329 - ..
223330 - Ran Intel IPDT test. As with prior tests, c22 passed the first test
223331 - with temperature 62 degrees below max. Astonishingly, Core Temp
223332 - showed all cores on processor #2 did not exceed 80, whereas all the
223333 - prior tests showed all cores > 90 and many reached 100 degrees. Since
223334 - temperatures on this test here at Fry's did not exceed 80, the fans
223335 - did not increase speed, and so there was no vibration problem today
223336 - during system testing.
223338 - ..
223339 - Congratulated Ken on successful repair of c22 without lifting a
223340 - finger.
223342 - ..
223343 - We ran 2 more tests, with the same result.
223345 - ..
223346 - Ran Passmark Performance test, and got same result.
223348 - ..
223349 - This seeming miracle of 10 degree drop in processor #2 temperature
223350 - aligns with erratic IPDT tests showing c22 easily "Passed" with both
223351 - processors 62 degrees below max, and other tests failed, demonstrating
223352 - a 62 degree swing.
223354 - ..
223355 - Ken feels results today, align with erratic c22 processor #2
223356 - temperatures > 90 degrees and up to 100 degrees, which is 10 degrees
223357 - above maximum 90 degrees for E5-2690v3 processor; yet, Intel Processor
223358 - Diagnostic Tool (IPDT) testing reports both processors passed by 60
223359 - degrees below max...
223361 - ..
223362 - This record seems conflicting and indicates c22 may be performing out
223363 - of spec...

223370 - Intel Processor Diagnostic Tool tests
223371 - 1 cor Max 100, 8 cores > 90, IPDT reports 12 degrees below max (78)

223373 -

223405 - letter on 160324 1118. ref SDS 34 Q94Y
223407 - ..
223408 - Accordingly, left c22 at Fry's. At this time there is no evident
223409 - solution to fix high temperatures on processor #2, to bring them into
223410 - alignment with processor #1 temperatures < 50 when all 12 cores are
223411 - run at 100%.
