Upgrade from i5-8400 to i9-9900k for po5-610 (Predator Orion 5000)

Hello everyone, my desktop is Orion 5000 po5-610. Based on the specs provided by Acer's website it uses a z370 chip set. I'm planning to upgrade my CPU from i5 8400 to i9 9900k.
Has anyone successfully upgraded your CPU system from gen8 to gen9 CPU (doesn't need to be exactly i9 9900k), based on my research gen 8 and gen9 use the same socket and my MB is z370 which is the highest level of chipset. So I think the hardware requirements are not to worry about, the most important problem is bios and chipset. Does all z370 chipset by default support both gen8 and gen9 CPUs or does it need to update the bios version to be able to run gen9 cpu? if the problem is bios I can get the latest bios version for it because all I can see on Acer's site is only one bios version but the description is all about supporting the newer Windows versions, not mentioning anything about updates to support higher cpu gen. Thank you!

This topic has been covered on this forum before, see “What CPU is compatible with the Predator orion 3000?” topic as this relates to your desktop cpu.

Thanks but my system is much older than the one mentioned in that post, they tried to upgrade the same CPU gen (12th to 12th) while I was trying to upgrade my 8th-gen CPU to 9th gen. I'm pretty new to desktops, I mostly used laptops before but I have read through some posts on other forums and they said some newer cpu gen will be compatible with older chipsets and sockets (in my case is i9 9th, and z370) but the older MB and chipset will need a bios updates in order to work with later released cpu.

Oh, I think you attached the wrong post but I did find the post you talked about.

I read through that post, and at the end, there was a user who confirmed that they could upgrade from i5 8400 to 9th gen the difference is they did the latest bios update version which is R01-C0 released in 2020 for model po3-600 but my model is p05-610 and on acer web site there is only one and latest bios version is R01-A release about 2019 and the description did not mention anything about the update to support 9th gen cpu. Is there any way I can contact acer for the bios updates file?

Yes, sorry my mistake, silly me🙃as that is the post I intended to give you a link to, as yes that post with the i5-8400 that he upgraded it to an i9, so I understand the situation with the bios, as its a different model.

The rule with Acer is that they list every update for bios as is and for about 1.5 years max, and once they have finished with all their updates for a specific model, especially bios updates and gpu firmware updates for mainly laptops, they don't update anything more on that model, so there is NO bios update for an i9 cpu for the PO5-610, there is no use phoning Acer up. Because oif the DDR5 memory Acer has updated many bios versions to accommodate new DDR5 ram also.

The only thing that you can do is either change the board for a better and more modem board or sell your PO5-610 desktop and upgrade to a new PO5-650 desktop that comes with an Intel Z790 chipset board and options for either the i7-13700KF cpu or the top of the range has the i9-13900KF cpu, RTX 4090 24GB GDDR6 and Acer has upgraded its ram to DDR5-5600MHz from its oem DDR5 4400 MHz / XMP 6600MHz, which seems like a real decent gaming/editing desktop, so look at this desktop.

Ah, that's sad. Is there any chance that the latest and only bios for my model were meant for Gen 9 support?

I just looked closely at the po3-600 bios list, there is one version that specifically describes support for Coffee Lake CPU which is the gen9th CPU. The release date is pretty close to the date of the po5 version, I think there are different models between po5 and po3 so the names and numbers of versions are not really important. I just don't know why they didn't describe the same for po5-610.
The interesting thing I found is there is another version of PO5-610 which was sold with intel 9th CPU different between my models and that 9th model is just the last four letters and the model before that was the same which is PO5-610, as I know the model which has the same prefix are pretty the same to each other on major components, the last four letters on each model will define some minor difference of the specs. One more thing is the 8th gen and 9th gen use the same model name and receive drivers from the same website so I think they must have similar main components to use the same driver for example 10th gen model will have different names and the the sites to download driver (po5-615). What do you think? Is there any way that I can confirm this or contact acer for information without wasting money for 9th Gen CPU:v

Nope, the 9th gen CPUs take a 9th gen chipset, the 8th gen take an 8th gen chipset. You can't mix them…

I think you misunderstood something. Because a generation of chipsets usually supports more than one generation of CPU, as long as they have the same socket. Intel also lists the processors that support by z370 chipset here:https://www.intel.com/content/www/us/en/products/sku/125903/intel-z370-chipset/compatible.htmlError I am pretty sure that the z370 chipset will support 9th gen cpu but for older chipset and motherboard they will need bios updates to support newer cpu but I cannot find the bios updates on acer website which indicates that updates for 9th gen cpu. So I'm asking about whether will i need to update bios to install my Gen 9 CPU or if is it already 9th gen supported out of the box, I also found some variants of my model which is po5-610 sold with pre-installed gen 9th CPU. https://www.amazon.ae/Acer-Predator-Orion-PO5-610-Gaming/dp/B07TFPPZJN
