The DH61DL motherboard says after a certain BIOS revision that it will work with Ivy Bridge processors. All of the ones we have are using the latest BIOS (version 120, the latest from Intel's site). If I put an i3-3220 in one of these motherboards with DDR3-1600 RAM will the board use the memory at the faster speed or will it still limit it to DDR3-1333 speeds?
Thank you for joining the Desktop Boards community.
The memory should work at the speed of 1600, this based on the fact that the processor and the motherboard support this type of memory.

I've put 1600mhz memory in several of these boards with Sandy Bridge processors, and all tests show that the RAM gets reduced down to 1333mhz. Memtest86+ shows it running that speed and so does CPU-Z.
Here's a CPU-Z report log of a DH61DL mobo with an i3-2100 CPU in it and some Hynix DDR3-1600 RAM. It says Memory Frequency is 665mhz, whereas if it runs full speed it should say 800mhz.:

Looking at the specifications in the previous post it does say "1600 O.C.", so it looks like it should. Guess it will be trial and error.
If you have the memory configured for automatic in the BIOS and it end up not running the highest XMP profile, then the BIOS discovered that the combination of processor, board and memory could not sustain the settings in this profile. In this case, yes, it is going to back off to the default (1333). Any one of these entities may be responsible for this issue, but I rather doubt it is the processor. In this case, I would consider it likely that the same thing will happen with the 3rd generation processor - but it is true that the 3rd generation processors handled 1600 slightly better than 2nd generation, so you never know. Nothing you can do but try it and find out. Worst that will happen is it will stay at the same speed. Either way, this would still represent a performance upgrade...
I went into the BIOS and found the settings to override the memory speed. It shows default already as set to 1600, but it's showing Active still at 1333. I tried going into "Memory Overrides" section and forced the speed to 1600, then rebooted and it still only shows it running at 1333. Memtest86+ also confirms this.
So it is capable of running 1600, but the Sandy Bridge CPU won't let it use it since it doesn't support it.
No, most Sandy Bridge processors supports 1600 just fine. Intel just doesn't officially claim that it supports it (and states that, technically, it is considered overclocking to run memory beyond 1333). I have multiple PCs with Sandy Bridge processors that are running at 1600 without issue.
In your case, if the default is to run at 1600 but you find that it is running at only 1333, this is an indication that the BIOS caught that this system -- this combination of board, processor and DIMMs -- cannot support 1600. You could insert a different set of DIMMs and see it work at 1600 just fine.
We had another system whose motherboard died that had an i3-3220 CPU in it. So I took the processor and tried it on a DH61DL with a DDR3-1600 Hynix memory stick. It shows running at 1600 speed just fine.
At least we have some upgradability on these boards.
