There's got to be a setting the bios conflicting the issue as I know a few in my head something about setting manually/enabled/disabled is mutli, c1e, timings, vt-d, bumping vcore/qpi voltages, c-states but that as far as I know

I thought similar, I set everything to default and deleted my OC profiles for the 920 just in case, basically everything auto or a mix of enabled. The majority of things in my OC profiles were disabled to run strong and lean. Still no post, then downclocked the RAM again to 1333, nada.

I want to give this CPU the benefit of the doubt before I say it's dead, pray. FWIW these are the CPU config settings I loaded initially (from my OC profile), and then set to system defaults (all enabled across the board now):

C1E Support: Disabled
Hardware Prefetcher: Enabled
Adjacent Cache Line Prefetch: Enabled
Ordering: Modern
Intel® Virtualization Tech: Disabled
CPU TM Function: Disabled
Execute Disable Bit: Disabled
Intel (R) HT Technology: Enabled
Active Processor Cores: All
A20M: Disabled
Intel (R) SpeedStep (TM) Tech: Disabled
Intel (R) C-STATE Tech: Disabled

EDIT
Well bless amazon for refunding and letting me keep the CPU, now I hunt for an x5670/50, going to cut my losses on the crossflashing. I feel this x5675 works on the right board. Sucks none of you guys are up here in the North with me, would gladly swap versus rolling the dice online.

you can use up to 40c/80t

What model is that board?

That Cinebench performance is not to shabby given the age of that system. 36GB of RAM though? Is that 9GB per CPU? Or is it all unified?

 

[Biolante]

its unified, but there were some compatibility issues because not all memories are identical. I had to figure out what population works at all. its a bit complicated
the IPC isn't great, that was all Netburst had to offer. A short time after release the system was already obsolete.

+ I believe that those are very power-hungry right?

True, but still, for netburst that performance isn't bad. It's actually a little impressive.

+ I believe that those are very power-hungry right?

Oh yes. NetBurst was very power hungry.

Netburst architecture was designed to get very large clock rates at the expensive of heat — and performance. ... One of the major reasons that Netburst was so terrible was branch prediction

rightfully so. had my electricity meter on it but can't remember the exact numbers, found it reasonable efficient if you compare it with a single cpu Netburst system

 

[lexluthermiester]

Netburst architecture was designed to get very large clock rates at the expensive of heat — and performance. ... One of the major reasons that Netburst was so terrible was branch prediction

To be fair, the Netburst design was an answer to a problem for the time. It was actually a brilliant design if you look at how it worked in detail. While it was an excellent solution for some compute tasks, it just turned out to be the wrong solution for many others. Intel tried to predict the direction software development was going to go and built an architecture aimed in that direction. Thing went a different direction and by then Intel was already invested. Thus came the Core architecture and the very serious leap forward it provided. Intel took a chance and learned from that misprediction.

Boiling liquid is also essentially how heatpipes and general refrigeration work.

Being playing with the setup lately as I'm dropping the voltages bit by bit at the minute vcore 1.264v (bios 1.27500v) QPI/DRAM Core Volt 1.26250v. As I trying to get the lowest voltage while keeping the 4.25ghz. As I'm using the daily usage to stress out the system like pcsx2 in software mode and encoding videos

Damn that cool to see

That's Nice is it 24/7 stable on that speed?

Holy voltage Batman!! 5ghz though!

That's Nice is it 24/7 stable on that speed?

I'd be surprised if it was. That CPU would not last long on voltage that high...

Aye....that's why I am asking.....

 

[Edwired]

I wonder what the temps are like

Those were in the screenshot above.

Only spotted it there wondering is it cooled by water or air

It's on water........

 

[Edwired]

Jeez nice temps. I don't know if I want to go with custom loop in my set up since the temp on the cpu never went pass 60c most of the time it bouncing about between 45c to 54c depending on what I'm doing on the computer most of the time it below 40c depending on the room temp and the weather

Added another fan for the nortnbridge it a blower style from an old nvidia 9500 gt with abit of cardboard and tape to make it blow air directly onto the heatsink. It works great
