EVGA Classified + 920 DO - goes 5GHz+ Wprime 1024!!!

[Raja@ASUS]

I have one 920 here that won't go over 210 even on this board. So the CPU plays the majority role. That being said, over 230 bclk needs the board to co-operate. Higher QPI bus frequencies are very demanding of optimal signal layout etc, which is typically where EVGA and DFI do a lot of extra work and it is beginning to show now.

This 920 has incredibly low leakage, it draws only 140w at 4.6GHz with 1.438Vid (we checked with a clamp meter) when cold (-85). Conversely, it needs lots of drive current when at ambient so hits very high temps at low VID (not to be confused with gate leakage). Intel must have found a way to increase substrate density which really helps when you go cold.

Not sure how many chips are out there like this as many have not started to bench them yet, or are using boards lie the REII which has high BCLK issues anyway.

oh i see

interestingly enough the CPUs that i;ve tried so far on Gigabyte UD5 have all come do a dead stop at 221MHz QPI basically.....everything benchable up to that point and then a restart when you try to go a hint better

i might try a new Extreme board they are sending with a D0 chip and see if things have changed i guess as last time i tested anything i7 at home, dinosaurs were still roaming the planet
