  1. You also need a lot of MCHv if you want to run PL5 or higher with high speed/tight timings.. 1.6+ MCHv or cold is likely required.
  2. The difference in GTL on the same CPU but different mobo is what led me to think that its not so much about the CPU..obviously if its not happy it will crash, but the reason for tuning GTLv at all... is the mobo! While id agree that 'yes' you do want the lowest stable VTT..but that requirement is for the CPU directly, whereas GTLv is only used to "fix" the noise created through the VTT circuit and bring the driving signal back into spec. Lets face it.. 775skt wasnt 'the pinnacle' of engineering/design lol. If the board has 'dirty' power phases that introduce a lot of jitter into the electrical signaling, you get poor results. Its no coincidence that the best boards for OC [even then] have premium power components. 2x of my favorites for DDR2/775 are the Gigabyte DQ6-X48 and the Asus Maximus II Formula. **to answer your Q. #1. GTLv is 'made' at/in the CPU by augmenting the VTT. On premium boards, the VTTv will be a single power phase near the NB.. which also has its own power phase [2x mosfet]. Yes they like to be cool..no more than ~40c though as NB will typically cold bug. LN2 or DICE on the NB helps tremendously with memory OC. I would run 1.48v NB for 1300mhz CL5 with cold.. 1.38-1.42v NB for 1200mhz CL6 on air. #2: GTL#0/2 and GTL#1/3 are in reference to the channels used by each CPU core respectively
  3. All core can run 4850mhz CCX1/2 @ 1.42v.. single core boosts fine to +5.1ghz on each core so far. This is 1 of 11 CPU.. all are B2 and within ~150mhz clocks on AIO. IMC went to mobo limit @ ~4400mhz C15 Very good!!
  4. Gunning Transceiver Logic: is a driving strength for core IO.. its important function is to reduce jitter/noise in the circuit which will occur at different voltages and clock speeds. Its a function of the mobo into the CPU. When youre adjusting GTL.. you need to understand how to calculate the actual GTLv you are creating. Every time you adjust VTT.. you have to recalculate GTL, as the produced GTLv is a ratio of the set VTT. Some CPU you will only need to tweak GTLv for 1c to make CPU stable.. others more. If youre running wprime and see 1x core far behind or ahead of others.. pay attention to it. GTLv settings will bring all cores into sync or push them out. In regards to your VTT question - it varies from mobo type.. as some have worse VTT circuit/droop than others. For cold benching wolfdales.. I typically run 1.38v - 1.47v for VTT and set the GTL for what i need after that.
  5. still a ways to go before its a 3.2 WR.. but taking global 1sts was nice reward for the effort https://hwbot.org/submission/4918446_ https://hwbot.org/submission/4918449_
  6. ITX poop.. 1.8vdimm limited ..will have to rerun with +PLL 3800 tight & 4266 slop
  7. So.. we just allowing obvious 5031mhz now in the LCC.. or mods asleep on holiday? Last time i checked.. subbing a cheat got you ban from comp. My how the bots changed.
