  1. Negative temps are extreme normally. I do not insist on moving to different league, I don't really care. The score is nice)
  2. High vpll moves up the fsbwall on 65nm cpus, low vpll is said to move coldbug down with 45nm cpus. Important note is 45nm cpus will die extremely fast if moving over 1.7-1.8v.
  3. Okay, here is the story on vpll mod for REX: 1. vpll is controlled with AS324 above PCI-E x1 slot. AS324's non-inverting input is controlled by DAC and we need to disconnect this DAC from pin 5 of AS324 and set the voltage on this pin manually. I had issues trying to lift the leg of AS324 and broke it so I had to completely remove AS324 and replace it with LM324 (same as AS324): 2. Before soldering LM324 back I have lifted up the 5th pin of this IC (the picture also indicates how to connect multiturn trimpot to lifted pin of LM324/AS324): 3. 1st and 3rd pins of trimpot should be connected to 3.3v and ground respectfully, middle pin should be connected to lifted pin of LM324: 4. The result is you can set any voltage you want in 0-3.2 range for pll, turning the trimpot: Tips: 1. You can use any trimpot however I recommend using >1kOhm. It acts as resistor divider that allows setting voltage on the middle pin in the range from ground to 3.3v (or 12v if you connect your trimpot to 12v). 2. I recommend that you use 65nm cpu - in case something goes wrong (wrong point of trimpot connect or disconnected wire etc) the maximum of 3.3v will go to cpu pll which is still safe for some time for 65nm cpus. Or, to be maximum safe, use no processor at all and check the pll voltage with motherboard started on the back side of motherboard here: 3. To be on a safe side and get 1.65-1.7v on initial startup I recommend that you set trimpot in the middle (so for 1kOhm resistance between left pin of trimpot and middle pin should be 0.5kOhm, for 10kOhm trimpot - 5kOhm etc).
  4. I have issues with my REX not posting after testing SS on nb (probably mositure somewhere under socket/nb) so cannot be 100% sure. Should complete the vpll mod later today if I fix an issue. vpll transistor is on the back side of the motherboard and I was not able to track the IC that controls the gate of this transistor. I think there may be two options - to control the gate with external resistor divider (this mod will allow switching back to normal mode) or trying to tie the gate to ground with resistor (but this will depend on PWM IC if it will stand it).
  5. It is. s478 cpu with adaptor for lga775 board
  6. for reference clock stage would it be fine if I use s775 mobo with adaptor?
  7. I can confirm cold on nb helps and wolfdales are bclk-dependant on temperature. With cpu@186W tec and nb @ss I can now boot to windows with 650fsb and high memory multies - however tec is not enough to make me run any tests (anyway, it was not able to boot windows with water cooling only @650fsb). Actually, cpu requires 1.75 vtt and gtl tweaking to go that high with water/tec. Maybe that is cpu that sucks but this wolfdale really scales with cold in terms of fsb in my test.
  8. Not really. I was looking for a bios that allows good overclockability of cedarmills and flashed 0206 as it is known to be amongst the best one for it (however didn't check if it helps with 65nm netburst). Performance is in line with 1301 if you set everything manually (and yet I need to work on baredit).
  9. I think perftune to low priority will help you George. Can you track if PL indeed amends the priority of p95-bench.exe - it should state it in the log. I don't bench modern platforms anymore but I think it is either you doing something wrong or the OS build which is not that much affected with this bug.
  10. I demonstrated this "tweak" at AOOC qualifier to der8auer a year ago. Thought this was fixed(( http://forum.hwbot.org/showpost.php?p=328647&postcount=73
  11. I also have performance issue in xtu with g550jk and this processor(
  12. Anyone knows if E8xxx are fsb limited with air? I have put my single stage on NB (-28C load) and cannot jump over 630fsb (630*6) with cpu cooled by all-in-1 water cooling at any strap/setting (before, I was able to push it to 660fsb with 1:1 cooled by ss). CPU itself is capable at least 4400-4600 at this cooling. Also, it seems like I should use single sided memory to go high memory clocks over 600 mhz fsb.
  13. I guess GPUZ won't detect nvstrap so that can be easily faked into GF2.
  14. I would create a reputation system for reporting. User with good repatation may report, user with bad rep may not. Reputation votes for user are available to mods only. So after reporting 10 good subs user is banned from report functionality.
