Here is a hwinfo64 & cpu-z snapshot for the suspicious chip: http://img02.taobaocdn.com/imgextra/i2/895640489/T2EVNvXupXXXXXXXXX_!!895640489.jpg It shows that the QDF code is QD77/QE83, with a max turbo multiplier of 57x (!), and the codename is Ivy Bridge-EP (-EP means this is a 2p...

Xeon E5-2600 v2 is comming soon. I found a CPU-z snapshot on internet: http://img03.taobaocdn.com/imgextra/i3/1084404919/T26aUiXmJXXXXXXXXX_!!1084404919.png Looks not bad, core speed=2.0GHz, 12c 24t, stepping=2, boost speed is unknown. Has anyone got such an E5 v2 cpu and folded with it?

The IPMI on H8QGL is incompatible with OCNG BIOS, H8QGL boards with OCNG BIOS would fail to post if IPMI is enabled, so it usually needs to disable IPMI by jumper (JPB1) before using the OCNG BIOS. But I like IPMI remote control functions as well, so I'm looking for if there is any method could...

As is well known that AMD Opteron 6200 series processor could support 4P at most. But look at this picture: http://news.mydrivers.com/img/20121101/s_d81015b7ef21474c99f44a158910d20f.jpg This is the motherboard used in Cray XK7, and we can see there are 8 Opteron 6200 CPUs! Is it an 8P...

Hi all. If you are running Opteron 6200s with '-psmax 1', I'd like to suggest you give a try to decrease the vcore of the chips, thus a lot of power might be saved. The default vcore setting is usually too high. For example, it's as high as 1.1250V for my Opteron 6272, but I find...

As we know, most E5 Xeon's multiplier is locked and unable to overclock. However, recently I have heard a rumor that the Q19D chip is probabaly unlocked, which is a E5-2648 chip @1.6GHz, 8C 16T, A1 stepping. Any one could confirm this? Thanks in advance!

Sorry for copy the title format from fastgeek just for fun. ;) Recently, I was also doing some performance tests on a 4P E5-4650. The best score I got is a min tpf of 6m50s for 8102, with a correspoding PPD of 972k. Seems not bad, however, still unable to reach the 1M PPD. Does anyone have...

As far as I see, thekraken's CPU affinity algorithm is basically to bind the N-th FAH thread on the N-th logical CPU in order. This method works pretty fine and looks like is the optimal binding order for AMD Opteron, however, is it also optimal for intel Xeon? I find a thread where a...

Has anyone noticed the fact that lots of CPU time used by the FAH is running in systime mode and probably just be wasted? Let's take a look at a typical result of top while FAH is running (on a 12C24T dual Xeon E5645): top - 14:07:51 up 19 days, 23:49, 3 users, load average: 22.45...

I read https://docs.google.com/spreadsheet/ccc?key=0Aspl6-RkaxtFdHdTdUdmUjhWalpXWVZ2S2xvejBDcHc and find there is a record for an overclocked 2P 6274 rig by Brainbug ([email protected], 64GB, TPF=17m41s for P8101 and 29m30s for P6904). These scores are wonderful! I tried to search more info about it...

Hi all, I don't know whether it was posted here before, recently I find that TurionPowerControl can improve Opteron 6200's performance significantly. All we need to do is running the cmd: TurionPowerControl -psmax 1 I have made a test on a 4p Opteron 6272 box, and detailed results are...
