Question about SuperMicro X7DAE Motherboard

1 Answer

I have XEON Core Duo processors with Dynatron heatsink fans attached. One of my CPUs is running about 8-10 degrees hotter than the other one and if I let it idle they both heat up until the alarm sounds at 75C. CPU1 runs the hottest and CPU2 runs about the same as the system temp - 8 degrees under CPU1. I have reseated the heat sink to the processors several times, switched fans and swapped the processors and the result is always the same - CPU1 alarms out at 75C with CPU2 and system about 8-10 degrees cooler than CPU1

Hello try to download the manual here:

http://www.supermicro.com/products/motherboard/xeon1333/5000x/x7dae.cfm

The fault could be a wrong setting in the bios chipset or cpu option.
Maybe one of the cpu has a wrong mhz setting ( overclocking )
This will make the system unstable.
75 degrees celcius is too hot even for a intel cpu.
Try to reset the bios to factory settings.
And look also for an bios upgrade.

WARNING!
Please do not download / upgrade the BIOS/Firmware UNLESS your system has a BIOS/firmware-related issue. Flashing the wrong BIOS/firmware can cause irreparable damage to the system.

Remember to add new cooling paste, not much, when removing the cooling element and fan.

Good luck

"In 2002 Intel released a 130nm version of Xeon branded CPU, codenamed "Prestonia". It supported Intel's new Hyper-Threading technology, and had 512KB L2 cache. This was based on the "Northwood" Pentium 4 core."

Meaning it is a Single-Core processor.

What is the main difference between a dual core CPU, and a Core2 Duo CPU ?


A dual core processor has two cores (essentially, two CPUs on one chip). Core2Duo is a specific dual-core processor design. Thus, all Core2Duo CPUs are dual-core CPUs, but not all Intel dual-core CPUs are Core2Duo designs.

Essentially all current Intel consumer dual-core CPUs today are Core2Duo designs. They have different names, but vary mostly in terms of their FSB speed (mostly, how quickly data can be transferred to/from RAM) and in the amount of cache memory in the CPU (cache memory is a relatively small amount of high-speed memory on the CPU chip that stores frequently-used data and instructions; it can improve performance 4-15% or so, depending on the amount).Best Regards, Luis.

All fans are working properly. System still comes on stays on for approx 2 mins and turns off.


CPU is overheating - the heatsink may be loose or no thermal paste.
Take heatsink off and have a look.
Go into BIOS and view hardware readings - watch CPU temp to see if it risees.

Heatsink for Dell Precision T5400


Actually what you need is a Heatsink & Fan for a Intel "Xeon" Processor. I believe some of these came with dual core and quad core CPU's. So make sure as to EXACTLY what type processor you have and look for a heatsink for that.

Or, you can call Dell directly and purchase it from them. Dell sometimes uses Fan tunnels in there machines, instead of directly mounting the fan on the CPU.

I hope this info helps, please rate my solution. Have a great day!

the better the cooling you can add to the processor the cooler and better your cpu will be. the 140mm fan is a case fan, yes?
you will need to upgrade your cpu fan and heatsink.

CPUs on 45nm core are overall cooler than their predecessors on Core micro-architecture. However, the temperature different under 100% workload makes only 4-5 degrees. The thing is that Wolfdale processor core is smaller and features higher transistor density within a semiconductor die, which makes it a little harder for the heat flow to dissipate properly. That is why Wolfdale and Conroe heat up almost identically in idle mode. As for the relatively low temperature of AMD Athlon 64 X2 6400+, with twice as high TDP as that of Core 2 Duo actually, it can be explained by the not very best location of the on-die thermal sensor that is situated quite far from the hottest spots of the processor’s semiconductor die.

Upgrading the cpu and heat sink and fan


Hi,
All the factory fitted CPUs are having such heat sinks as previously u were having.
Check on the backside there will be small plastic covers where screws fit these could be removed by screw driver but u can purchase that heat sink or can use previous heatsink as well if it is working.
