I have recently upgraded my Motherboard and am now looking at RAM. I have an ASRock N68C-GS4FX Motherboard and a AMD Phenom II X4 940 Processor. I have used the CrucialPC system scan application, and in the memory window it does suggest upgrading to DDR3 RAM (as it would fit in the Motherboard), but I was under the impression that my Processor would not work with DDR3 RAM.

That motherboard supports both AM2(+) and AM3(+) socket CPU's, hence the confusion. AM2 CPU's will only work with DDR2 RAM. AM3 CPU's, on the other hand, are backwards compatible and will work with DDR2 or DDR3 RAM. Thanks @sunk818 for the clarification.
The AMD Phenom II X4 940 is an AM2+ socket so it will NOT support DDR3 RAM. This is because you have a hybrid motherboard.

Manual seems to state AM3 is backward compatible with DDR2: http://download.asrock.com/manual/N68C-GS%20FX.pdf
Ah yes, I will update that. – MC10 – 2015-08-05T17:01:26.100

The AM2+ Phenom 2 x4 940 does not support DDR3. Only the AM3 version Phenom 2s support both DDR2 and DDR3, because they have dual memory controllers built-in.

2Yes; You have two DD2 slots and two DDR3 slots per the manual. – Ramhound – 2015-08-04T11:13:37.620
2If the CPU is AM2+ it cannot run DDR3 RAM. Only AM3 socket CPU's will run DDR3 RAM. – MC10 – 2015-08-04T11:15:28.933
4I linked to the manual for a reason. Why is this question getting upvoted consider it shows zero research effort? – Ramhound – 2015-08-04T11:26:07.807
It may not be as easy to find the information regarding the sockets and supported RAM types. The motherboard is confusing as it is a hybrid motherboard. I upvoted simply to remove the negative but now it has risen. – MC10 – 2015-08-04T11:33:54.007
11@Ramhound Your comment "Yes; You have two DDR2 slots and two DDR3 slots..." is misleading as the answer is no. The manual does answer the question at the very bottom of page 17, "DDR3 memory module is only supported by installing AM3/AM3+ CPU." but it's easy to miss that. – Luna – 2015-08-04T11:35:10.053
@MC10: Why do you upvote on your opinion on the downvotes, and not your opinion on the question? – phresnel – 2015-08-04T11:57:58.923
@nallar - I disagree that my comment is misleading though. – Ramhound – 2015-08-04T12:08:10.830
15@Ramhound: Your comment is misleading. Saying "Yes" when the answer is "No" is the definition of misleading. – qasdfdsaq – 2015-08-04T12:46:52.957
1@Will It seems the CPU is a dependency whether you can use DDR3 memory. You should edit your post to include what CPU you intend to use so the best answer can be given. – Sun – 2015-08-05T16:04:16.333
1@Braiam Your edit removes crucial information - the answers depend on what processor is used, and you removed it. Please roll it back. – Luna – 2015-08-06T10:34:14.570
@mokubai if you are going to revert the edit, don't leave it as crappy as it was originally! – Braiam – 2015-08-06T22:17:56.933
@nallar sorry, it wasn't intended. I knew that the graphics card wasn't related, but I somehow removed the cpu information along with it. – Braiam – 2015-08-06T22:19:15.610
