Z620 - CPU performance is slow

HP Recommended
Z620
Microsoft Windows 10 (64-bit)

Looking for help with my HP Z620 workstation. The CPU performance seems lacking

 

Running CPU UserBenchmark test in bottom 5% of tests across users with same CPU
Also, Lightroom CPU intensive tasks (Preview generation, Export to JPG images)
consistently runs slower than my laptop (i7 2670 QM mobile chip) for CPU heavy tasks (GPU is working great)

 

HP Z620 workstation
Windows 10 Home
Dual intel E5 2670 CPUs
96GB of ECC DDR3 clocked @ 1333 MHz
BIOS settings:
  power mgmt - Turbo mode
  multi processor - enabled
  Active Processor cores - All
  Hyper threading - enabled

 

Windows power mode - High performance

 

Accoording to the HP Advisor program, all the fans are running

 

CPU temp never gets above 60 degrees

 

As comarison:

My laptop CPU temp - reaches into the range of 60 - 67 degrees

 

Any suggestions?

Windows 10 msconfig.com seems a little buggie,

 

https://www.youtube.com/watch?v=luGZC-5DeQA

 

In Boot tab, advanced options - (per video) it was only allowing selection of 2 cores, not the 16 cores that Device Manager showed. It seems that the solution is to select '1' in # of processors, Save, Reboot, then running MSCONFIG again all 16 cores appeared as an option. Selected 16 & saved, rebooted again. After that all 16 cores showed in Task Manager, benchmark went up to over 13,000.

 

FIXED!

Hi,

 

Why are you quoting your laptop temps as a comparison?  It makes no sense.

 

The Intel E5 2670 was first launched in 2012 and some versions are in "end of life" status.  Modern Intel i7 processors depending on the tasks will be superior compared to the the early version of the E5 2670 XEON.

 

If the GPU in your work station doesn't handle video correctly then the processors will be used for off loading tasks.

 

There are different versions of the Intel E5 2670 and yours could be at the bottom of the barrel compared to the v3.

 

You should be able to use Windows 10 performance monitor to ensure that all processors and threads are correctly working.

 

Depending on the installed dimms, the  1,333 version in your workstation might not be the load reduction dimms.

HI PaulZ620,

 

Can you  upload or list your passmark results for comparison?(and what version of Passmark you are running?). [EDIT - Sorry just realised you are using CPU Userbenchmark but you could try Passmark to see how that compares]

 

I noticed you are running only1333MHz Dimms which is a little unusual since even the E5-2670 V.1 processors support 1600MHz Dimms. This will of course influence the Passmark results.

 

FYI, for comparison here's my Z620 results when I ran with 2x 2670 (v1) CPU's and 64GB 1600MHz Dimms. P.S. I actually have 1866MHz Dimms installed but they run at 1600MHz - limited since I only have the v1 CPU installed. The xeon v2 processors run at 1866MHz so was just planning ahead fo future upgrade(s).

 

PassMark 27-10-2016.JPG

 

In case the above image doesn't load my 2x E5-2670 reults are;

 

PassMark V8:

 

Score 4713, CPU 19665, 2D 602, 3D 4606, MEM 2062, DISK 12464

 

PassMark V9:

 

Score 4450, CPU 18879, 2D 574, 3D 4758, MEM 1817, DISK 12934

 

Initial build; 2x E5-2670 v1, 64GB 1866MHz (8x 8GB), Quadro K4200, Tesla M2090, additional Syba 2x SATAIII PCIe card, Samsung 256GB SM951 M.2 (AHCI) PCIe boot drive, SanDisk Ultra II 480GB SSD, 4TB and 2 TB HDD

 

Current set-up; As above but with 1x E5-2690 v1 (one of the 2690 CPU's I bought was DOA so still looking for a second 2690).

 

HP Z620 - Liquid Cooled E5-1680v2 @4.7GHz / 64GB Hynix PC3-14900R 1866MHz / GTX1080Ti FE 11GB / Quadro P2000 5GB / Samsung 256GB PCIe M.2 256GB AHCI / Passmark 9.0 Rating = 7147 / CPU 17461 / 2D 1019 / 3D 14464 / Mem 3153 / Disk 15451 / Single Threaded 2551

Thanks Brian

 

here's my benchmark - I can't see your image, it just shows a place holder. Its way under the rating listed on Passmark, trying to figure out why its so slow, just got the system.  What # did you get?

@Brian1965

 

HP documentation does indicate 1333 mhz dimms but it also indicated that 1333 mhz load reduction dimms were shipped in later releases.  Not having the better dimms could be a reason for the lower performance.  Perhaps the "memory mark" would show that difference.

Hi Big_Dave,

 

I was only trying to indicate that the E5-2670 (v1) CPU's supports 1600MHz memory (as well as 1066, 1366 & 1600MHz).

 

http://h20331.www2.hp.com/hpsub/downloads/z620_memory_configurations.pdf

 

The faster the RAM installed, the better will be the overall system performance.

@PaulZ620

 

While your solution is probable it would most likely never be a Windows bug. I have never encountered a Windows processor checked bug with updating W10 on multiple platforms.  While your fix may have solved the issue it's not likely to occur.

 

As indicated by the video, the number of processors is unchecked by default.
