Too much time to turn on display

[Yasin3321]

I had a hp z400 with w3520 processor. I wanted to upgrade my processor so I bought w3680 and it's working fine but takes 5 to 7 minutes to turn system display on ( showing hp logo and bios options). I tried putting back my old processor and it's turning on display in 3 to 4 seconds. My bios is latest 3.61. what could be the problem.

W3680

Hp z400

Hi Yasin3321,

My bad!

Should have checked your Workstation specs.

Figured you had done this.

Processor support per HP is:

• Intel Xeon W3503, 2.40 GHz, 4 MB cache, 1066 memory, 4.8GT/s QPI, Dual-Core
• Intel Xeon W3505, 2.53 GHz, 4 MB cache, 1066 memory, 4.8GT/s QPI, Dual-Core
• Intel Xeon W3520, 2.66 GHz, 8 MB cache, 1066 memory, 4.8GT/s QPI, Quad-Core, HT, Turbo
• Intel Xeon W3540, 2.93 GHz, 8 MB cache, 1066 memory, 4.8GT/s QPI, Quad-Core, HT, Turbo
• Intel Xeon W3570, 3.20 GHz, 8 MB cache, 1333 memory, 6.4GT/s, Quad-Core, HT, Turbo

You can confirm at this (Link). HP is not officially supporting a W3680 on this motherboard.

No BIOS update for this. HP does not support Windows 10 on your product.

Sorry.

• I have seen it and it does support this processor.
• I think their new bios is having trouble with this processor so they updated their web page because a week back I saw it on the same web page it was listed there w3690.
• And I have taken this processor from my near market and It was running on a hp z400 the only difference was i had bios 3.61 and his computer had 3.20
• Same year both were manufactured. I know if anyhow I can downgrade my bios it will work normally.
• If there is way to downgrade bios please let me know.
• Thanks for ur help . 
• U can download the hp z400 manual from the link given above.

Hp sells it's z400 with w3680 and w 3690.

I have taken this processor from a working hp z400. He bought that from hp.

The problem is that he still has default bios 3.20 which came with system accidentally I updated my bios to 3.61. it's the problem of bios. Is there any way to downgrade my bios to default 3.20. our systems are manufactured in same year. But I bought it for a bit low price so I had 4 core processor and he had 6 core processor. 

Hp updated their web link because I do remember 6 core processors were listed their. Before their bios update. 

Please let me know if there is any way I can flash default bios 3.20 . 

I can guarantee it that my problem is gonna be fixed.

Thanks , regards

Hi,

You're very welcome.

Sorry, I can't find BIOS version 3.20 using any HP supported operating system.

Have you talked to HP Support about this problem?

I flashed my old bios through USB.

It corrupted my bios . Then I downloaded latest bios from hp website and flashed bios through USB . 

Now my system starts in 2 to 3 seconds.

BTW thanks
