Dear Forum,

  I wanted to share some little mod project I was kind of forced to do, in hoping this could be useful to someone... here is my story:

  I ordered a 2nd hand z620 for a little virtualization project. After I ordered a 2nd hand riser card for the 2nd CPU. Unfortunately, the riser card came without CPU heatsink. Given its specificity, I had to either find and order the specific riser card CPU, OoooR consider other options. Coincidentally I had seen a low-cost single-block 3rd party liquid cooling solution that according to reviews was outperforming most of the 2-block ones AND had the water pump outside (as opposed to having it in the very same heatsink, making it very slim... It could fit for almost the same price!

  Of course I wouldn't unbalance the system by having one CPU air and the second CPU water chilled, I had to take 2!

  The first problem was "where" and "how" to install (2) single block chillers. I would have been easier with a custom-made water chill solution, but the prize would have skyrocketed.

   Only at the back the pipes would reach. But there I would have to leave some space to put the cables. At the same time, some antivibration should be considered. I had some plastic wall-cable holder that could to the trick. Then I bought some screw bars (4mm to the case, 3mm to the fans)...

  I used the same holes existing in the case to put the screws and fix the bars.

The distance from the case allows me to plug all usb/network/etc cables at the back.

  I unmounted the rear fans and with a "dremel-like" tool, I cut a frame big enough for the heatsink heads at the top...

  I thought I could have saved the original plastic covers, but, as you can see, due to the stiffness of the pipes I had to chop with the dremel some otherwise now useless plastic parts...

  You can also notice I had to take out one of the rear fans (the upper one) for the external cabling and piping to enter the case.

  After some unrelated problems with QPI (see https://h30434.www3.hp.com/t5/Business-PCs-Workstations-and-Point-of-Sale-Systems/Since-upgrading-Z620-from-dual-E5-2630v2-to-dual-E5-2660v2/m-p/6267606#M18108)

   I started to have FUNwith FANS...

   The system is pretty picky if it misses a FAN (i.e. you have to press a key to boot everytime), so the objective was to use every fan connector in a way or another. This is the motherboard schema:

  Each Chiller came with (2) cables, (1) for their fan with a 4 pin standard, and (1) 3 pin for the pump. It is ok if the pumps work always at 100% as they are not that noisy... for the 4 pin:

  on the z620 motherboard the pinout for CPU1 (19) and CPU2 (20) is different...

  The "Tach1" is for the "sense" as it reads the fan RPMs and the "PWM" is for "Speed Control", so you have to connect the 1-4 pins in order, and you should be ok.

  I planned to plug the pumps with an adapter to the +12v and use CPU1(19) and CPU2(20) for the chiller fans. There is a "problem" however... The z620 expects "more" RPMs from the fans. The original HP fans are smaller and speedier (3600rpms as I checked with a fan control panel), so connecting the slower fans there led to fans at high speeds at all times!

  I wanted the system to speed up when hot using PWM, so this solution wouldn't work! However, the rear fans AND the original CPU1 fan are both 3600rpms!, so then I connected both to CPU1(19) and CPU2(20) using insertion board cables you can buy in an electronics shop:

For CPU1:

For CPU2:

  The 2 speedy fans (3600rpms) were now connected to CPU1 and CPU2 connectors, but I still needed to plug the chiller fans!

  The chiller fans are those 4pin connectors above, but I had a connector (24) that controlled the 2x rear fans!, unfortunately the connector is 6 pin, and I need 2x 4pins! so some cable hacking is needed.

P24 is a 6pin connector with the following layout

1 - GND

2 - +12V

3 - Tach1

4 - PWM1

5 - Tach2

6 - PWM2

So, for the 4pin 1st chiller fan we connect:

1 - (1-P24) GND

2 - (2-P24) +12V

3 - (3-P24) Tach1

4 - (4-P24) PWM1

For the 2nd chiller 4pin :

1 - (1-P24) GND

2 - (2-P24) +12V

3 - (5-P24) Tach2

4 - (6-P24) PWM2

  This ended the wiring and everything looked like this:

Hi Guys.

My Question is does this motherboard can handle the i7 3770K?

I'm on BIOS 2.05 I think if I remember (I'm at work).

Any comments?

I'm looking at this http://h10032.www1.hp.com/ctg/Manual/c03612798 and the highest one is the i7 3770

Thanks!

No errors in the eventlog.

No Problems in built-in hardware tests.

No Minidump.

System is running on Windows 10, 64 Bit.

Searching for reasons why the workstation randomly freezes, any suggestions?

I am using Hp z600, has 2 processor xeon x5675, I recently realized wich only one cpu is working. Since a couple of months I upgrade to W10x64 (on W7 everyting was working  fine).

Right now:

- BIOS recognize 2 cpu and all the theads are enabled

- DeviceManager show 24 processors

- Windows task manager show only 1 soket, 6 cores

- Graphic software I'm using show only 6 cores

I already try to:

- unmount and switch the cpu

- change the motherboard and update the BIOS to the last version

When I changed the motherboard w10 just ask me to restart from a previus point, so I don't have format again.

Can be really Windows?

Next step I'll try to format again. Thank you in advance if someone have a good idea!

Is there another part number for the - HP 606020-001 Hard Driver for the G7 Server Dl380

Hi Everybody , im having the same error , 942-Memory Training error - Dimm 3 CPU0 :

I replaced 4  other memorys ( Ram ) , Cleasr cmos and nothing happend . I tryied to replace CPU from socket 1 to scoket 0 and the error now is appiring in Dimm 3 CPU1 . 

I replaced the Cpu 1 with another CPU E5-2620 like the other cpu , error persist again . 

i dont know what to do more !!! 

Hello community !

As we all love our workstations , I have a rather big issue with my Z600.

Because I was curious if I can set my second GPU to compute , I set the option and restarted the machine. 

Problem is it didn`t boot anymore (of course).

I tried clearing the CMOS with the buttoon , and that led me to the BootBlock Emergency Recovery Mode.

It requested a new BIOS to be flashed , so I got a bunch of CD`s (USB didn`t work whatsoever) and tried to flash. 

All of the images flashed , but the issue is the following : 

1.It says I should remove the power cord , wait 5 seconds and then reboot it. Can`t I just use the power button ? Am I doing it right by following the exact inbstructions appearing on screen ?)

2. When I manage to boot it again , fans go wild for a few seconds and then to normal. Power illumination goes from blue to black and then RED starts blinking 8 times. After this I am again into the BootBlock Emergency Recovery Mode , doing the same as step 1.

Any suggestions how can I fix this without going to an HP Certified Service center (I probably won`t have the money to pay the service , as it is out of warranty)

Looking forward to replies , this is kind of urgent

Thank you in advance !

I'm reinstalling Windows 10 from scratch on an HP Z820 and I've been unable to find the driver for the device identified as PCI Serial Port in Device Manager.  I tried running and manually installing sp74499.exe from Paul_Tikkanen's ‎09-08-2017 11:52 AM post in this thread, but when I did, it said it could not find the device for this driver.

The Hardware IDs listed for the device are 

PCI\VEN_8086&DEV_1D3D&SUBSYS_158B103C&REV_05
PCI\VEN_8086&DEV_1D3D&SUBSYS_158B103C
PCI\VEN_8086&DEV_1D3D&CC_070002
PCI\VEN_8086&DEV_1D3D&CC_0700

Anyone know where to get the correct driver?

Fellow HPians,

In March, when preparing  z620_2 (Xeon E5-1680 v2 8C@4.3GHz/  z420 liquid cooling / 64GB / Quadro P2000 / HP Z Turbo Drive 256GB + Intel 730) to add music production to it's 3D CAD and graphic design duties, I updated the BIOS from v.3.91 to v.3.92, which was only a few weeks old at the time.  This was done using the .EXE in Windows as I've done  many times before on the five HP z-series I've had.

During the upgrade, the progress bar showed the 3.91 BIOS saved and 3.92 flashed successfully. However, quite soon the screen went black and after a pause, the fans began spinning up and I shut the system down on the power switch.

Looking in the user manual, there was a crisis recovery jumper mentioned for the z820, but not for the z420 or z620.  Assuming the motherboard had been ruined, I bought a replacement and - stupidly in retrospect-installed 3.92.

The system ran, except that the Quadro P2000 that had tested in Passmark Performance Test as high as 9030 in 3D, was now testing as low as 7646 and the 2D that had been 874 was reduced to 549. 

As the Z Turbo Drive Windows installation was high mileage and the configuration of a new UEFI Windows 7 installation was proving elusive without buying a new copy of Windows, a Samsung 860 Evo 500GB was installed with Windows 7 from the orignal HP recovery disks, plus all the software reloaded.

The results from the P2000 were improved a bit- 8038, 8126, and etc., but the the 2D remained very poor.

The P2000 was exchanged at PNY for a new one who were very good about it, but the results were only very slightly better. TO run while the P2000 was away, I decided to give GTX a try and bought an MSI GTX 1070 Gaming X- which is on the edge of not fitting in the case- and while this had quite good in 3D- 11350, the 2D was also terrible for that GPU on a system tunning at 4.3GHz - 579.

Meanwhile, having learned that the z620 has a crisis recovery jumper, I was successful on the first try using the .bin file on a FAT32 USB but- most stupidly of all, recovered the orignal motherboard to 3.92.

Susprise! the performance was the same. At the same time, hearing rumors about performance issues with 3.92, I decided to reflash z620_2 to 3.91.  However,  five attempts, from Windows in Safe Mode and from USB, in the first 3 tries had an "unrecoverable error" that was "unknown" and in Safe Mode the flash was shown as sucessful, yet restarting revealed that the BIOS remained v. 3.92. Of course, the graphic results were the same. The subsequent two attempts to revert to 3.91 produced the same result.

I decided to try the P2000 in one of the 3.91 (z420_1 and z420_3) systems and upgraded z420_3 from a Xeon E5-1607 V2 (4C@3.0) to E5-1620 V2 (4V@3.7/3.9) / 16GB /changed the GTX 660Ti to the Quadro P2000 / Samsung 860 Evo 500GB + Intel  and the results were revealing:

Remember that the 860 Evo was straight from z620_2.  The 8419 3D and , especially 755 2D were more like it, considering that is comparing the results on 3.9GHz to 4.3GHz.

Subsequently, I checked Passmark results for the P2000 and was surprised to see that the 2D results vary so considerably. The top 2D mark is 1354 on i7-7700K @ 5GHz, but the shock is the bottom mark of 133 on a Dell Precision T5820 / Xeon W-2133 3.6/3.8 - a currently available system, a Threadripper 1950X @ 4.1GHz = 267, and HP z440 E5-1630 v4 @ 3.7/4.0GHz:  682- not terrible, but not up to z420_3's E5-1620 v2 of 2013.  A very interesting result was an i7-7820X 8C@3.6/4.5GHz/ 64GB/ Samsung 960 Pro M.2 and the P2000 results are 2D=634 and 3D=7944. That is also not as good as z420_3 with an E5-1620 v2.  Of course, the HP 3.92 BIOS can not be at fault in the non HP systems, but:

Q1: What is going on?

As the two z620 motherboards using 3.92 have the same results, whereas the 3.91 results were proportionally similar to the original z620_2 @ 4.3GHz with 3.91, I'm convinced that 3.92 is at fault.  This may have some relationship to Spectre/Meltdown considerations.

A straight question for HP:

Q2: Can BIOS V. 3.92 be reverted to V. 3.91 or NOT?

I had purchased HP Workstation with OS Win 7 Pro 64 bits. Also purchased ASUS GEFORCE GTX 1080 GPU. Once installed the GPU to mother board and power on, GPU is not starting. GPU got 2 power socket (1 with 6 pin and other with 8 pin) but I have only 1 PCI power cable which I connected to 8 pin socket.

Hi

Got Hp Z1 workstation g1

No post, black screen fans spinning, nothing at all

ITs the xenon with quadro 4000 gpu

i have tried everything clear the bios, reset the memory and gpu with no luck

have someone any idea?

Product Number: G6F30AA#AB4

t620/W8/4C/16GF/4GR/W/TC

Spare Number: 768245-001

BID = 14WWFTCM603#SAB4#DAB4

I had a t620 with a failed hard drive. Had this same one replaced for the 3rd time in a year with the same issue.

This time the replacement comes (after waiting 4 weeks - no stock in New Zealand and maybe Australia?), I boot it up and find Windows is not activated. Plug in ethernet, does not activate automatically.

I go into Windows Activation and find the message: This product key doesn't work. You might need to get in touch with the store or company you brought Windows from, or you can buy a new key from Microsoft.

No thanks MS I should already have a licence with this TC.

Notice the the product key is showing *****-FVR83.

After repeated attempts it does not work.

I use ProduKey to get the BIOS OEM Key. Paste this into the product key area. Get the same message.

Thinking this is an image problem I use ThinUpdate and download the latest image (WES8-64 Image 14WWFTHM601 Sept 2017) dated 30/3/18.

Re-imaged thin client. Get exactly the same result. No activation.

Called HP and logged an issue with the replacement. They eventually log in and see the issue.

They spend 30 minutes trying to check the BIOS key which they confirm is correct. They try to activate with the key and get the same issue I am getting.

They say it's a software issue and to re-image the thin client. I did this a 2nd and 3rd time, same issue.

Eventually get another replacement sent to me. It has the same problem!

While dealing with this I get another identical t620 W8 TC from a different customer with a failed hard drive and log a warranty case.

Get the replacement. Same issue again right out of the box! It will not activate.

This time the issue is escalated, the person went over re-imaging the TCs, activating the keys etc.

I find that 2 of the TCs do no even have BIOS OEM keys - or at least ones that ProduKey cannot find.

I notice the the product key is showing *****-FVR83 on all repacements I have recieved. This must be part of the image.

The person on the phone says it must be a bad unit and he will get it replaced. They assure me the next ones will not have the same problem.

In the mean time I decide to try earlier images via ThinUpdate. There were ones from 2015 and 2016 listed.

The re-imaging process works as usual but the TCs will not boot with either of these images, say no boot device detected.

I try 2 different thin clients and 3 different USB drives, same issues.

I get the 4th replacement from the courier. Plug it in. Can you guess what happens next?

SAME ISSUE, WINDOWS WON'T ACTIVATE.

I have wasted hours on this troubleshooting and on the phone with HP.

I have waited days, weeks for replacements and I have gotten nowhere. HP tell me no one else has reported this issue.

I cannot belive this - this must be a bad batch of t620s I am in the middle of OR their image is screwed.

Can anyone assist with this or give advice on where to go next?

When Windows updated to 1709 and then 1803, my nvidia graphics card no longer worked properly.  I lost my multple displays and my grahics and monitor drivers defaulted to generic.  Before upgrading the grahics card, I need to know if the motherboard will support the change, or if the OS is just too much for the hardware.  As Windows 10 worked fine with the card until the fall creator update, I am not sure where the conflict trly is.  If it will take a newer graphics card, any suggestions on what might be compatible?   (it's a PCI)

Thank you

I bought the Z620 used, about a year ago, for CAD work and folding (F@H).  After folding for approximately 6 months on the CPUs, the system locked up, black screen, fans screaming (i assumed a thermal overload protection mode or similar).

It took me a few days to figure out the issue, but the second CPU riser seems to be the culprit ... specifically the black power input plug.  

The system has been running fine for the last 6-8 motnhs without he 2nd CPU riser card installed.

The input plug, from both sides (cable harness side and CPU riser side) are both melted.  I would like to get this problem resolved but i dont want to fry another input plug / CPU riser board.  

I am unsure if the only problem with the riser card is the input power plug or if something in the card has caused the plug to melt.

Without having another sytem to plug the card into, how can I start tracking down the root cause of this problem?  

hello... please help me...

My PC using  core i5 - 6500 and i upgraded CPU to core i7 - 7700..

and i can't start my PC (use core i7 -7700)

please help...

Hello,

when I am using SecureBoot and UEFI, my computer cannot be restarted or shutdown. If I try to restart the computer, it goes into a kind of suspend mode. For switching it off correctly, the power button must be held down for a long time.

Only if I switch off the SecureBoot in the BIOS the computer behaves normally.

I am using Windows 10 (64bit) 1607 LTSB.

The BIOS Version is: 00.02.71 Rev.A

Best regards

Hi
I have a HP Compaq 6200 Pro (XL506AV) computer with I3-2100 processor, I bought a new i5-3475s processor, but it doesn't start, beeps 5 times and nothing else happens.
What it means and how do I turn on the computer with a new processor.
