Z620 upgrade to E5-2640 V2 CPU?

Regarding your mention about the IME firmware upgrade..... that actually is done from the command line interface on even the original motherboard, and it has nothing to do with changing firmware in a fashion that gives one a different boot block date.  I wrote up a How-to on that.... the process is a bit fiddly, and some of the posts about that in this forum have said it can't be done, but it is meant to be done if one wants, and I've personally done it.  I don't use those IME upgrades.... I'm running in the legacy mode of BIOS, but I just wanted to see if I could do it, and you can see the version number you upgraded to from within BIOS easily.  HP has had a mess in its listing of the IME firmware versus software upgrading in its drivers update site for a long time.  Changes of names, versions, where they put the different parts, wrong placement of the SoftPaqs, etc.  It is unnecessarily confusing.

PCIe generation 1, 2, 3 issues:  In the xw6400 all PCIe slots were Generation 1.  In the xw6600 only the two video PCIe x16 slots are PCI Generation 2 (and all other PCIe slots  in the xw 6600 are Gen1).  There is a HP comparison PDF you can find discussing the differences between the Z600 and the Z620, and that has info on which slots are Generation 3... in the Z620 only.  In the Technical and Service manual there also is a block chart that shows the chipset and details the slots regarding this issue.  It should be pretty easy to find in the HP Z620 brochures.  I doubt you'd see much of a difference from a PCIe gen 2 to a PCIe gen 3 card, all other factors remaining constant.  The best bang will come from a "version 2" motherboard transplant into your original Z620 and a nice Ivy Bridge processor upgrade.  Agree on the memory.

WIth regard to the Management Engine firmware - as you said it doesn't get updated when doing a bios flash using the standard HP method, however the ME firmware code actually resides in the bios image in the ME region  and is thus a componenet of the HP bios file. As such if we take the latest v3.91 bios file from HP and burn it to a flash chip we get both the v8 ME firmware and the 2013 boot block date. 

Z620 owners - can you tell me the exact details of the bios chip in the Z620?

With regard to the PCIe 3 speed on the Z620, if you are using an Nvidia card and a Sandy Bridge CPU (v1) make sure that you apply Nvidia's patch to unlock the PCIe 3 speed, since without this it is by default restricted to PCIe 2.

Hello SDH

And Large mercy to  you this answer.

I seņs thus comforted. I am not at all specialist and I am a little randomly seeking on Internet of the solutions.

I fell in love with HP series Z, last November I bought one Z800 (nine,never used, never connected, 460 €) to pour my daughter, I have make some improvements, it functions perfectly.

In this moment, I buy one Z620 (375 €) makes it is equiped with one E5-1607 V2 (no 1605 désolate), and my project is to put the extension of motherboard for a 2nd processor (147 €) and of installation my 2x E5-2640 V1 (Paid 65 € 2 the, new ones)

Made thank you thank you grant Your assistance  !!!

I am already in way  to negotiate a Z840, But it's dared to be with length and complicated because I convey do not have gross june reprocesses and I can not expensive payer….

With very soon

Best regards

......Excuse me to  my average English.......

Bonjour à tous 

et désolé de vous parler en français mais mon anglais est franchement déplorable.

Alors, pour mon Z620, reçu avec un E5-1607 et 8go de RAM. J'ai donc trouvé une carte d'extension pour un deuxième processeur, et j'ai installé les 2 E5-2640 que j'avais en stock, et poussé jusqu'à 24go de DDR3 10600R (j'attends 24 de plus). Windows 10 sur Samsung SSD 128. Ca tourne franchement très très bien.

14 secondes pour ouvrir Windows ! Et surprise, je joue a des jeux de 2014/2015 type Tomb Rider, Shadow of Mordor, etc. tous détails fond avec la ...... quadro K600 en place !!! Je souhaitais investir dans une 680 4gb à petit prix ou une 1050TI, mais je me dis que pour le moment je suis bien et pas cher avec la petite quadro (mieux qu'une FX 3800 que j'avais en stock et que j'ai essayé).

Voila, Je nai pas encore reçu le ventilateur de CPU pour mon Z800, il doit être sur un bateau ....., je n'ai donc pas encore pu tester si je pouvais mixer un X5650 et un X5670 sur la même carte mère. A suivre

Bonne année à tous et à bientôt
