Does a 13700F processor support DDR5 6000 CL36 ram?

[05032-Mendicant-Bias]

I'm choosing parts for a new build. I found contraddicting information online regarding what exactly does an F part locks.

F locks the multiplier, which prevents CPU core frequency overclocking. K parts have unlocked multiplier.

I can't find information about memory overclocking (I use the XMP profile):

• 13700F : The ark page for the 13700F shows 5600[MT/s] as the limit.
• 13700K: The ark page for the 13700K also shows 5600[MT/s] as the limit! But this part can run DDR5 faster, either through XMP profiles or through manual tuning of the timings
• Chipset should have no effect on memory speed, the difference between Z790 and H770 should be mostly PCI-E connectivity
• Motherboard quality affects maximum speed a lot because of the traces. E.g. This Z790 MOBO claims up to DDR5 7600 MT/s speed
• Options available through the bios also affect what you can change

Since I don't overclock, I would like to avoid a Z790 MOBO with an overbuilt VRM and go to a cheaper H77 MOBO.

 

Question:

1) Does the 13700F support DDR5 faster than 5600 through XPM profiles?

2) Do H770 motherboards support XMP profiles?

Yes but it will legally be called as overclocking and technically you voided your warranty if you do so. Even if XMP didnt pop out, you can just manually enter XMP speed with locked/+.05 extra on your RAM voltage. Just keep your mouth shut during RMA and youll be fine.

Yep. Intel completely backed out on their kerjiggery to lock out RAM overclocking from all but Z board, but i would still go for B series chipset not only for guaranteed access, but also improved VRM and more overall connectivity.

They went 2/3 of the way with backing out of there kerjiggery. The Hx10 boards still do not support memory overclocking. Only 500 series+ Bx60 and Hx70 boards allow you to set a RAM speed above the official CPU supported speed. (That and, obviously, Z series boards, but Z series boards have always allowed memory overclocking)

 

Also, with locked CPUs, you aren't allowed to change the Gear to Gear 1 after reaching a certain memory speed, which means that you are limited to effectively DDR4-3466. I forget what the DDR5 equivalent is, but you'll lose performance by dropping to Gear 2 after that.

The "supported" ram speed thing seems quite common. I think it is best to look at it as manufacturer support, distinct from silicon support. Manufacturer support is what Intel (or AMD) will back you up if you have problems running standards compliant ram at that speed. That specifically excludes XMP and similarly I'd expect EXPO to be affected also. Silicon support is what it can really do, but the ultimate limit is down to design and luck.

 

Keep in mind the difference in support is not unique to Intel. Later AMD AM4 CPUs officially support to 3200, which is the number you'll find in their official documentation, yet they even say 3600 is the sweet spot for enthusiasts pushing further, but if you have problems at 3600, they're not going to help you at all.
