FSB Strap on DFI LANPARTY UT NF680i LT SLI-T2R
To complete our portrait of DFI LANPARTY UT NF680i LT SLI-T2R mainboard we need to check out a few more things. The next test was used to determine at what frequency FSBP Strap on DFI LANPARTY UT NF680i LT SLI-T2R mainboard changes. We used Everest tool in the interval between 325MHz and 490MHz FSB with 12.5MHz increment (50MHz QDR).
Here are some comments to the chart above. At 462MHz FSB the mainboard booted the Windows but failed even a simple test like one-time memory speed measurement in Everest. At 450MHz and 437MHz the board wouldn’t even start. At 425MHz it passed the test and then showed a BSOD. As we already know it also failed to run stably at 412MHz FSB. In other words, DFI LANPARTY UT NF680i LT SLI-T2R is hardly operational at all in the FSB frequency interval between 400MHz and 475MHz. That is why it was just my luck when I attempted to “jump” over the FSB Hole right to 475MHz, no higher and no lower.
The chart shows very clearly that FSB Strap changes somewhere within this interval. And the performance drops so dramatically that even at 490MHz FSB we couldn’t hit the same result as at 425MHz FSB. During our tests the timings were locked at 5-5-5-15, but as we will see in the next part of our test session, even more aggressive timings of 4-4-4-12 won’t let us close the gap.
