I just might not ever use another DFI board again. After spending days overclocking testing for stability and making sure I had the perfect settings my DFI Lanparty UT P35-T2R decided it wasn’t going to work at all. I began getting continuous reboot cycles and when I finally would boot was constantly get bios errors or have the board not recognize my mouse or keyboard. (PS2 or USB) Not only that the constant boot cycles at times more than 30 in a row corrupted my hard drive. Is it a Bios problem? Is there an incompatibility with the Yorkfield chip? Right now your guess is as good as mine, I even tried my Q6600 again and still no dice. By the way I’m still waiting to hear back from DFI tech support after leaving about 10 messages on their “No one is available, well call you back if you leave your name and number” machine.
Luckily I was able to get a decent overclock before all this happened, that was 3.825 Ghz, FSB at 425 x 9 and DDR2 9200 Ram timings of 5-5-4-12 with 333/1066 for the divider. Other settings including voltages were CPU at 1.3500V, NB 1.37V, RAM 2.23V, Thermal management; disabled and C1; disabled.
By now you have read the results with this overclock, and can see that even with an overclock of just 800MHZ the performance increases tremendously not just in one benchmark application but all.
I would have hoped to at least have the screenshot of the overclock with CPU-Z but even on another system my data in not accessible. So when I get back the DFI motherboards from RMA or get another board that supports the Yorkfield processor, I will go ahead and update this page with not only a screenshot but possibly an even higher overclock. Thank you for your understanding.
