DFI UT X58-T3EH8 continued - Part 2

[Sam_oslo]

oh by the way, anyone tested the board using prime in ultra high bclk level but QPI Fast Link enabled? please help...I wonder if I hit a bclk wall on my board or my chip...very hard to get to 228 bclk with QPI enabled...

I have not tested any ultra high BCLK, but tried to find the highest 24/7 stable BCLK and i hope it can give some indications/help on max-BCLK. I found @4.01GHZ (211x19) 1.15v to be the sweet-spot for low-volt, and @4.2GHZ(210x20) 1.23v to be the best stable OC on my air-cooling in summer-time.

My w3520 + DFI runs rock solid with almost no tweaks up to BCLK212 with 19x, and up to BCLK210 with 20x. I haven't tested the 21x fully and won't know how stable it is, but it seams to be prime-stable up to BCLK210 with almost no tweaks (VVT:1.23v, NB Core.1.13v, the rest on stock/default).

I have also tried to Prime up to 221BCLK @4.2GHZ(19x221) too, but these will usually end up in BSOD after 10-12 minutes, and seams to need more voltages/teaks to run stable over BCLK212.

I have had several prime-stable run at @4.1GHZ(216x19), but it won't pass memtest/LinX without extended voltages/tweaks which makes it seams to be related to IMC/RAM-limitations on my setup.

I have had some fun-shots at @4.62GHZ(220x21) too, but never tied to push it further to find the ultra high BCLK (no volt-shock for my hot low-volt babe yet).

All my tests are done with QPI Fast Link enabled,
RAM 6x
Uncore 16x
QPI 18x
