Massman Posted January 21, 2010 Share Posted January 21, 2010 For those who do not know, I was at the MSI Elite OC Summit in Taipei this week to test and provide feedback to the MSI team. The actual overclocking was on the first day of the summit (on monday) from 11AM to 18PM. I was mostly testing out the Clarkdale overclockability on the Trinergy and then switched to LN2-ing the 5870 with 1h30 left to go. Anyway, here are the results ... sorry, no system pictures. I'm sure that many people will post a lot of pictures in the next couple of days. I was amazed that it was actually possible to run Wprime so close to 6G with this chip as initial LN2 tests lead to believe me that this chip was hardly capable of 6G. With only 1.7V and ~105°C this should actually be a pretty decent chip. I was always booting in windows at this frequency ... ran the 1024M just to complete the benchmark list. Had about 1h30 minutes when starting to prepare the system. Card went really high without doing any effort ... no tweaks, didn't check any scaling. The ref design suffers from serious OCP, tho, which kinda sucks. This was ran at 1.47V and ~ -100°C. Conclusive thoughts: I ran this exact combination at home a couple of weeks ago. Due to serious vcore/memory issues, that session lasted exactly 10 minutes, so I'm sure you're not surprised when I say that I was a bit skeptical when booting up the first time. Messing around in the bios a bit seemed to show the real power of the Trinergy and I'm liking it more and more. For reference, here are the three main issues when dealing with this mainboard: 1) You will have coldbug and coldbootbug! I had them at -90°C and -110°C. Clarkdale is scaling insanely with temperature, so MSI will have to figure this one out if it wants to see high frequencies on a lot of chips. 2) The memory dividers are, not surprisingly, a drama. On air cooling, the BCLK oc difference between 2:6 and 2:8 was 30MHz(!): with 2:6 I could boot into windows at 220MHz no problem, with 2:8 only at 190MHz. Maybe consult Gigabyte to fix this one? 3) For this specific bios, the upper vcore limitation was 1.7V. Above 1.7V, it looked like there were no actual bios settings (although bios said there was) and setting a higher vcore resulted in a non-bootable system. FYI: I was running bios 1.2B3. Also tested bios 1.2B4, but this one was worse, so quickly returned to the B3. Quote Link to comment Share on other sites More sharing options...
