Upgrade Z820 with a second CPU

HP Recommended
Z820
Microsoft Windows 7 (64-bit)

Hi,

 

I have a Z820 with the following parts:

 

Motherboard:

System board (motherboard) assembly - Supports 2S/DDR3 1333 MHz memory (Patsberg) - For Windows 8 Professional

708610-601

  

CPU:

Intel Xeon Eight-Core E5-2640 v2 64-bit processor - 2.0 GHz (Ivy Bridge Romley-EP, 20MB Level-3 cache size, Intel QPI Speed 6.4 GT/s, 95 W TDP (Thermal Design Power), Socket 2011/LGA2011)

733617-001

 

Heat Sink:

636164-001

 

6x RAM:

Hynix 8GB (1 x 8GB) DDR3 PC3-14900 1866MHz

 

So my plan is to buy a second "Xeon Eight-Core E5-2640 v2 64-bit processor - 2.0 GHz" and double the RAM. 

 

I can't find a manual of the motherboard...

 

What do I have to consider?

BIOS setting? Jumper on Mainboard? Power supply Watt? 

 

Thanks for any information!

 

best regards,
Fredrik

you might want to try google using keywords "HP z820 service manual"

 

also, the z820 has two diffrent heatsinks the stock one for low power cpu's and the optional 130 watt cooler for the high performance cpu's  since your cpu is 95 watt either will do, but if possible look for the 133 watt one

 

also the cooling shroud has a space for the second cpu cooling fan. if your shroud lacks this look at the sec link

 

the case also has a slot for a second cooling fan

Thanks a lot for your help!

 

I found a lot of manuals, FAQs and technical support stuff. But no single one about "how to install a second cpu". But let's see. I will buy the cpu, the suggested heat sink and identical RAM and put it all into my Z820. 

I hope that it will work. And otherwise I hope it will give me some peep-signals 🙂
