[Request] Adding 7th Gen CPU support to Fujitsu D3430-A1
#1
Hi, I purchased a FUJITSU ESPRIMO D556/E85 a long time ago.

It currently has an Intel® Celeron® CPU G3900 (Spec code SR2HV) installed and I have a spare i5-7500t (Spec code SR337) that i would like to put inside.

Thing is, the FUJITSU ESPRIMO D556/E85 motherboard (D3430-A1) only supports 6th gen while is conterpart FUJITSU ESPRIMO D556/2/E85 motherboard (D3430-U) supports 7th gen (cf: https://cdn.cnetcontent.com/d1/1e/d11e89...ddf840.pdf)

They both run the same chipset but have two different motheboard model.

Mine (D3430) has a BIOS update that you can find here:
https://support.ts.fujitsu.com/IndexDown...53DD334A7E

while the one supporting 7th gen(D3430-U) has a BIOS update that you can find here:
https://support.ts.fujitsu.com/IndexDown...A1569244B6

While i tried putting my i5-7500t in the slot, it would not boot. The cpu would just get hot but nothing would show on screen.

I was tempted to try and update by D3430 with the D3430-U BIOS update but my knowledge in BIOS is really weak and I would prefer not to brick my Motherboard without anyone's advice.

What would you suggest ?

Regards,

Just truncate D3430-U1.UPD to 8192 KB and flash by a hardware programmer.

Am I supposed to flash the truncated .upd file ? I was thinking about using a ch341a.

Desired CPU compatibilty from (microcode donor): FUJITSU ESPRIMO D556/2/E85+ (MoBo model D3430-Ux, Latest BIOS from manufacturer) can run 7th gen. Intel processors

My (slightly older model) PC: FUJITSU ESPRIMO D556/E85+ (MoBo model D3430-Ax, Latest BIOS from manufacturer) can not run 7th gen. besides running same H110 chipset and similar MoBo.

Hi guys,
I fell into some issues with the Fujitsu Esprimo D556/E85+ (MoBo: A3430-A14 GS 2). It runs an Intel G4400 CPU (6th gen.) without issues. I`ve seen online same PCs running 7th gen. processors (as it`s got an H110 chipset, I thought it would be plausible), so I bought an i3-7100. Unfortunately it doesn`t start. So I went to the Fujitsu CPU compatibility list, and bought another CPU, an i5-6500. Doesn`t run either. After some research I found some guys running into similar problems have modded the original Fujitsu BIOS with upgraded microcoede for gen.7 processors, unfortunately I haven`t found ready-to-flash file, so I ask you kindly to help me with that matter. Maybe you have that BIOS ROM-file ready to post here, or maybe you can guide me through the modding process.


CPU compatibility list for both MoBos.

Post a screenshot of Mainboard tab of CPU-Z.

Check it with other motherboard.

*I need few days for doing that, after checking back and forth with all these CPUs unfortunately I run out of thermal paste (I like to use good/proven one, like the Noctua NT-H1). Ordered fresh one today, but expected delivery is on the 4.10.2023 (would come on 2.10. normally, but that day I took off, and that is because 3.10. is independence day in Germany). So can't do the screenshot now.

*Only have this Fujitsu D556 and another mobo for 4th gen. Intels, so no possibility to check at this moment. I will ask some friends if someone else runs on LGA1151. Also, the seller assured me he tested the processor before shipping. 


Meantime I also tried your suggested solution from another post on same BIOS, but I failed (yes, I bought this "CH341A pro" J-Tag only for that purpose, I am struggeling with these CPUs for some time now....). (Thats the reason why the thermal paste went gone too, haha.)
Not sure if I should post the detailed results here in this thread, or should answer in the other thread. I am not very familiar with posting on any forums (somehow barely needed that tool in the past), sorry about that.

Thank you for your support that far anyway!  Heart

Itried but I think I made wrong file size.
I used CH341A Pro. The chip on the MoBo was W25R64JVSSIQ. I did not find same chip in Neoprogrammer repository, so I chosse a close one. Dont have the trunc.exe file in Windows10 Pro, nor does this software work when I copy it on my HDD. So I used another method: fsutil.exe. After truncating I was able to programm the EEPROM with this *.UPD file, but after the flash the BIOS went dead (no problem as I got the contact pliers, and I made backup, and I have another 2 PC with same configuration...)
I think I truncated to 9000000 or something....my bad Smile
I will try to correct in few days when I am back at home.
Once again, I appretiate your help, DeathBringer!

After examining all these CPUs, I run out of thermal paste (I use the Noctua NT-H1). It takes a few days. Ordered a new one today, but it won't arrive until 4.10.2023 (we took off on 2.10. since 3.10. is German independence day). We can't screenshot currently.  space bar clicker
