 |
|
So I just discovered today that my server uses a LGA771 socket. I bought it for $93 a couple years ago. It has two Intel Xeon E5430s. The Xeon E5430 uses LGA771, just like the Jayhawk I bought.
Can a server run with one CPU? And if so, can I put the Jayhawk in my server?

| One CPU is fine. Jayhawk will fit, but it may not work due to BIOS detection and microcode issues. Also the design is power hungry and may damage your motherboard. |

I'll risk it. It's not like I ruined a $500 server  . Thanks for the info by the way!
Anyways, what will happen if the Jayhawk is just a thermal test vehicle? Will my server even boot up?
I'll be able to tell you guys the results before this weekend if the thermal paste I ordered from Amazon arrives on or before Friday. |

| If it's just a thermal test, I don't think it will boot, since its not an actual CPU. |

I like that way of thinking!   |

Me too! Experimentation is the only way we learn! |

Well I got to test my Dell PowerEdge 1950 with the Jayhawk. I believe the Jayhawk is a thermal sample.
I got an "intrusion error" at first when I plugged in my server. When I fired it up, the server ran for 1 second, then stopped suddenly, giving me an "E122C CPU" error.
Also my server works just fine after the testing. I put both E5430s back in.
Also, I put the Jayhawk in both CPU slots.

| E122C is a power error. The board has decided not to fire up the CPU as it's determined that it can't supply the chip's power requirements. |

Myth: Not busted
How many watts do I need to run a Jayhawk? My gaming computer has a 750 watt PSU. I don't know what wattage my server's PSUs are. |

Did you tell the BIOS that you were running as single processor? You would need to use the first CPU socket. That error is when testing CPU power fails. It may just be that it doesn't recognise the CPU, or it could be a dead or duff die.

I have to tell BIOS that? That may be the problem. I don't remember how to access BIOS. I think it was during startup where you have to press F# to access BIOS. I'm planning on testing it again later this week when more thermal paste arrives.
So I have to go into BIOS, then go where to change the CPU settings? And should I change settings with both E5430s installed or just one? |

| It's not about the PSU wattage, it's about what the board's regulators can deliver. Also, even if your board's regulators could deliver enough power, the board may not let that happen. The board is testing the input resistance of the CPUs power supply lines. It is failing the CPU for not being within the expected range for the chip the board was designed for. That usually happens when the chip is a dud (ie short circuit). That might be the case here, or possibly the resistance is just lower that expected. Jayhawk/Tejas was rumoured to require about 50% more power than Prescott. |

Crap. Is there anything else I could do to see if there's even a chance of running the processor? Changing BIOS settings? Could this failure also be due to the possibility that the processor is a thermal test vehicle? |

I don't think that it being a thermal test vehicle is what's making the difference here. The easiest way to make a chip create as much heat as the genuine article is to have it draw the same power.
Maybe there's a BIOS or jumper option to disable the second socket to make more power available for the first socket, or possibly to disable some of these tests entirely, but that's unlikely. It seems your board is trying to do you a favour by not letting you destroy it lol.
That said, if you have the option, you might want to try manually specifying the CPU speed and voltage to the lowest the board will do. Less voltage = less current = less power drawn. It probably won't help, but you might get lucky. |

You can also try to see if it will boot with one of the known good processors, without changing BIOS settings?
On the "Thermal Test Vehicle" note - isn't a Thermal Test Vehicle just a resistor, consuming as much power as a real chip? i.e. - would the server even be able to report an error if it was a TTV? |
