der8auer Posted June 10, 2012 Share Posted June 10, 2012 I benched a lot with GIGABYTE UD3H and Sniper 3 in the last weeks and I keep getting a CBB between -60 and -80°C. If the system freezes the debug LED always shows 15 which is the code for memory detection. Even if I straight hit the reset button after the freeze the system does not reboot. After few seconds it just shuts down and I have to warm up to the said -80 to -60 °C. Any ideas how to solve this issue? I'm wasting a lot of LN2 with cooling down the whole pot and cpu all the time. BIOS (boot) settings: 107 BCLK 50 CPU-Multi 1:11 Memory (1177 MHz, 7-11-7-26 1T) Voltages: 1.8 vCPU 1,225 VTT 1,225 IMC 1,8 vPLL 1,815 vDIMM Quote Link to comment Share on other sites More sharing options...
Christian Ney Posted June 10, 2012 Share Posted June 10, 2012 (edited) Using UD5H, never had this, BIOS F8c CBB was same one I had using the MVG when I clr cmos, if I dont clear cmos then with 106mhz and 1.8vcore no CBB nor CB at all, only have CBB when I clear cmos and it was at -144/-150 on both UD5H and MVG Edited June 10, 2012 by Christian Ney Quote Link to comment Share on other sites More sharing options...
der8auer Posted June 10, 2012 Author Share Posted June 10, 2012 It's pretty strange becasue also other members of PCGHX Team have the same issue but different CPUs. Sometimes the UD3H seems to boot without any CBB and few minutes later it has a CBB at -80°C. Crazzzy85 had the same issue and changed to MVG and no CBB there. So it's not a CPU issue.

Christian Ney Posted June 10, 2012 Share Posted June 10, 2012 German boards are harder to cool No had this issue but had other issues though, tried to warm the memory slots ? Quote Link to comment Share on other sites More sharing options...
splmann Posted June 10, 2012 Share Posted June 10, 2012 Also no problem with UD3H when i at bclk 105 ! Quote Link to comment Share on other sites More sharing options...

Will try that Also no problem with UD3H when i at bclk 105 ! Which BIOS did you use? I tried S2, S4, F8g Quote Link to comment Share on other sites More sharing options...

der8auer Posted June 10, 2012 Author Share Posted June 10, 2012 About how much? Quote Link to comment Share on other sites More sharing options...
Massman Posted June 11, 2012 Share Posted June 11, 2012 PLL voltage can move up/down CB, but doesn't affect CBB that much as far as I know. Maybe a component on the board getting too cold? Quote Link to comment Share on other sites More sharing options...
der8auer Posted June 11, 2012 Author Share Posted June 11, 2012 I will try heating up the board while benching. Good idea. Quote Link to comment Share on other sites More sharing options...
der8auer Posted June 11, 2012 Author Share Posted June 11, 2012 Crazzzy85 tested the same CPU on UD3H and on M5G. No CBB on M5G but CBB at -80 on the UD3H. Same settings. So it must be a board related issue. Quote Link to comment Share on other sites More sharing options...
sin0822 Posted June 11, 2012 Share Posted June 11, 2012 hey on your GB board, when you fail at very cold temp, just press power button as rapidly as you can possibly more than 1 time, like tap tap tap lol. also BCLK=CBB and CB helper, only like 103mhz is needed. Also i tend not to use the benching BIOSes, but it shouldn't make much difference. I think Sniper3 has better CBB behavior than UD3H, which i think is worse than UD5H. depends on the benching tho, E1>E0 for better CBB behavior.
