HP z620 Bios Flash - Help Boot Recovery Mode

[DGroves]

based on your boot description,  YOU ARE NOT IN RECOVERY  MODE

you system in not even getting to the bios recovery state

your ram:  BALLISTIX 4GB ddr3 - 1600 UDIMM 1.5v is incorrect the RAM MUST BE "ECC", your ram is not ecc

http://www.crucial.com/usa/en/bls4g3d1609ds1s00

the above is why the system will not even get to the pre bios stage!!!

remove all non ecc ram, and make sure any installed ram is "ECC" ram, and is in the proper slots

Do they all need to be the same style as in all 8gb or 4gb sticks of the same brand identical copys, or may I mix and match different ddr3 12800 dimm ecc?

I can only have RDIMM ddr3 in this machine?

please read the previous message whhere i took the time to post the link to the HP memory docs for your system

it covers memory types, placement and how many sticks needed for one/two cpu systems

and note" RDIMM is a diffrent memory module NOT TO BE CONFUSED WITH DDR TYPE MEMORY

you need 3 sticks for one cpu so guess how many you need for two cpu's (hint read the hp memory doc!!)

[ryanmu]

Okay,  someone said on a forum somewhere about 16gb rdimm ddr3 stricks being possible.

[DGroves]

why will you not read and follow the HP directions on memory?

your refusal to do so is what causes you to post links such as this:

https://www.ebay.com/itm/202273731708

that link is for NON ECC ram, and will not work!!!

 again, RAM MUST BE "ECC" type............

Registered "ECC" ram is also supported and required for larger memory configurations

you want to pay 800.00 Us dollars for six 16GB registered ecc ram? be my guest

plus some 8gb stick here and there

[ryanmu]

So I booted up with 6- 4gb sticks; 1-8gb stick, and a 16gb( for fun)  plus I have 3 more 8gb.  It works case closed Thank you.

I have the same problem:

After plugging in power the system starts with a blue led in the power button, fans low but after about 30 seconds all fans go to maximum. No beep, no output on monitor, no response to keyboard or anything else, usb-key with the J61_0394.BIN file in its root, usb-drive led never flashes.

System hardware has not changed, ran fine before.

I tried removing or disconecting as much hardware as possible, no hdd's, no usb devices, removed all extra cards (except graphics card), swapped memory, ...  only thing left is without graphics card or exchange CPU.

I got into this mess after a bsod "driver_irql_not_less_or_equal" while flashing the bios from within Windows 10.

So I am pretty sure my bios is trashed, so hoped to get it working again with the bootblock recovery.

No matter if I change the jumper to recovery (1-2) or normal (2-3) I get the same behaviour.

Any thoughts ?

As maybe you know I also bricked of my Z620. 

Hardware: I only start with one CPU (0), one memory stick (Slot 1) and with USB stick DOS bios 3.91. 

Bootup: Recovery jumper 1-2. 

First start Beebs 8

Second start 8 beeps

Third Bios startup and then it hangs. The flash starts but it never progresses more then 0 %

Any ideas? Really need some help on this one.
