Sorry i missed your reply. The 6366HEs would run extremely slowly. Pb0 power state on those is only 3.1 GHz. Since they are a production processor power states are locked down, and the only way to up the speed would be to increase the ref clock using OCNG on a supported SuperMicro server...
Hi, The reason i downcored this way (ie using "Compute Unit" is that i read specifically in section "2.4.3 Processor Cores and Downcoring" of the Family 15h BIOS and Kernel Developers Guide, that the disabled cores are CC6 power gated and shut off. It states:
"• Both cores of a compute unit...
Thanks :) It has been fun :) Albeit a bit of strange fun pushing these. The scary part of it being... wondering whether one of the 6 phase VRMs on this SuperMicro server board will go up in smoke or not :) I've got the SC748 fans blowing across the ones on the front for processor 2, but the...
i think my system is a bit short. i just did a Cinebench R15 run and the score came out to 1420cb. All 16 cores running at 4 GHz. Ref clock of 205. Temps were 43C on processor 2 and 39C on processor 1. Have not tried running it with all 32 cores yet since i actually do not know if all 32 cores...
interesting thread.
i just replaced the four of the Opteron 61xx ES chips (48 cores at 3.0 GHz) in my Quad Socket H8QGi-F with a set of Opteron 63xx ES chips (32 cores).
16 cores in a G34 package got rather toasty, so i ended up doing a "Compute Unit" downcore to 4 Piledriver cores per die (8...
it was possible to disable it on the previous gen multi cpu Istanbul setups (i ran a dual Opteron 8439SE a while back on a Tyan board). i currently run a SuperMicro H8QGi-F with 4 Opteron 61xx (which also uses HT-Assist/Probe Filter)... there is no way to disable it that i am aware of.
Its very interesting... going by the posts here... it certainly seems that i am not wrong. A lot of folks here are *still* stuck on Russian collusion even though the Mueller report came out and said that nobody in the campaign engaged in it. i think i'll come back to revisit this again in...
so its been some months... are you still laughing?

That is honestly impressive. The 3900X is almost at the level of my overclocked quad Opteron (48 K10 cores!) which scored 7459cb multi. Maybe its time for me to upgrade soon. Its amazing how much progress AMD has made.
i heard that the L3 in Phenom was more optimized for servers. If you check out the A8-3870K you can see that getting rid of the L3 didn't affect much. i also read a while ago that the L3 determined the upper bounds of write performance for Phenom. Someone correct me if i am wrong.
Actually latency is not too bad... between 64 and 70 ns for the threads running on the same die, and slightly higher if the threads are sharing data in main memory but are on different dies in the same socket. Yes its best if you not go off socket if you can... but even if you do its not so...
i found something rather interesting last night with my old rig.
It seems most of the cores on my K10 based Quad Opteron 6100 setup are capable of running 3.8 GHz. Some 3.9 GHz. 3.8 takes about 1.325v. i haven't tried 4.0 GHz yet with voltage beyond 1.35v due to heating issues.
At 3.9 GHz i...
My system is unusual (most folks do not run a server grade $800 motherboard with quad opterons for their personal desktop PC), but its most definitely not flaky... i've run it through hundreds of runs of Intel Burn Test with no issues (with it soaking up over 1000 watts through the wall socket...
