Are there any x470 motherboards that will support a Ryzen7 5700G CPU without a BIOS update? I know most of them will with a BIOS update but I do not have an older CPU to use and they do not have BIOS flashback like many x570 models, at least that I've seen. Will a x470 work at all with a 5700G? I could download the BIOS on another computer and the use it to flash the memory with only limited functionality from the CPU. The 5700G does not support PCIe 4 so I do not need it. The 470's are quite capable of fulfilling my needs and PCIe 3 is plenty fast.
Many thanks,
Len

Many B450 and B550 boards have 6 SATA ports. When you populate the 5th and 6th port, however, it will probably use the PCIe lanes used from something else...usually a PCIe slot, sometimes a secondary M.2. That will probably also happen on an X470 board, although you might still be left with one more open slot.

In both cases you have to pay close attention to the asterisks in the storage and PCIe expansion ports sections of the spec sheets. They can be a bear to decode sometimes.

some motherboard can do bios update without cpu

List of (B350, B450, X370, and X470) motherboards with USB BIOS Flashback

I made a list of (B350, B450, X370, and X470) motherboards with USB BIOS Flashback This feature allows your to update the BIOS ***without*** a processor, memory, or video card. USB BIOS Flashback comes in handy if you are, for example, going to use 3rd gen Ryzen and the motherboard doesn't...

Maybe some MBs made quite recently but seller should know. It has limited PCIe lane because of it's IGPU.

Thanks a lot for the list. However none of the 470 boards have any video out ports (DVI, HDMI) which I need for a 5700G. I would need to buy a video card which I want to avoid right now with the prices sky high.
It looks like I may have to wait a while till or get a 570 board.
Thanks for the help though,
Len

Mine has a display port and HDMI, easily convertible to DVI and even VGA.

Btw, great MB.

Thanks and it does look like a great MB, but I don't see BIOS flashback so I wouldn't be able to use a 5000G without flashing the BIOS which I can't do without buying an older CPU.
BTY, I know HDMI is easily convertible to DVI and VGA I already have adapters I've done that with and vice versa. I have two HDMI TV/monitors and would need to convert the Displayport to HDMI or DVI. I have a passive adapter but I think I would need an active to do that. Do you know if the MB would support a passive adapter? The active adapters are very expensive and ASUS doesn't mention anything about that.
Thanks for the help,

Why do you need X470? They're really only useful when there's a unique requirement for more PCIe lanes.

B450 boards are plentiful, come with BIOS Flashback and as well video output ports for APU's. B450 Tomahawk MAX is a great choice in particular. Or B450m Mortar MAX: it's an mATX board but it has a second M.2 socket that supports PCIe gen 2 NVME's with 4 full lanes.

They're not that expensive. I will get one just to have the tool even if I don't need it. It say it works with most 24/25 series EEPROM SOP8 chips. Does that include most motherboards?

Thanks a lot for the info,

They are very common in this application. Just look at your chip for markings, look for something like "25Cxx or 24Cxx" marking. It's tiny, use bright light and magnifier.

SOP-8 refers to chip package form factor: 8 pins, small outline plastic. Or maybe parallel...or planar, can't remember, meaning leads in two rows, preformed for planar (leads flattened on the same plane as the bottom surface of the chip body) surface mount.
