Aurora R7 - 2933Mhz HyperX memory option?

Forgot to say: have a Dell 2933 if you're looking for one.

You have the correct number.

Did you set up an OC User Profile and specify XMP1 under Memory?   This is not explained in the docs.

I'll say more if you wish.

How much? :-)

For those who don't know, DIMM slots tend to come in matched sets, the lock tabs are usually two different colors, seen above as black & white. Dual channel is achieved in the photo by placing the DIIMMs in matching slots, here, paired in the white slots. Note: these appear to be factory installed, but just because we see them in the white slots does not mean that is the proper slot; generally, when one memory stick is used it normally goes in slot 1 - on the mthrbrd you can almost always see printed text that explains which slot is which - the next 'rule' would generally be to place the 2nd stick in slot 3 & achieve dual-channel. Slot I tends to be the outermost slot; regardless, dual-channel happens in white or black, quad happens when all four are in there, research more online if you get bored

CPU-Z may be able to tell u if you're in dual-mode, see my screen shot

My friend has 8700k, new Cine-Bench R15 CPU score is 1725 (I screen grabbed the prior 1713) how close is yours?

he's almost at a stable 5.3, stable meaning works long enough to do all popular benchmark suites, won't be long now

Problem here is that the service manual (pgs 76 and 19) says the opposite: for two DIMM's, use sockets 1 and 2.  Which is what I'm doing now.  Can we resolve this?

The manual is wrong, I read the manual thought it was odd and tested 1,2 & 1,3, & 2,4.  The memory performance using geek bench drops in half when using 1,2.  The other two combinations seem to be equivalent.

OK, I believe you.  But the memtest I tried seemed good.  I'll try switching.

Assume that CPU-Z tries to be perfect but isn't 100% right, but you can try to use it to check. If a newer version pops out next month for download as a revision, it may have updates etc that clear up errors 'now' in the version you have etc

So. I used qualifying statements like normally or generally, where 9 times out of 10, you match with the color of the tabs (black-on-black / white-on-white), that's why they're different colors, lol. Others prefer to go by their owner's manual & hope it isn't an error in printing. If the PDF is in error above then it is (the same Dimm1/2 is stated in the R6 manual), I'm prone to take their Guide at face value though, or otherwise would, except we see Ryan notices a performance hit from going by the manual. Next we consult what the factory did, and as you saw they're using white/white or 2/4. Technically, the data can move at the speed of light faster in Dimm1 than Dimm2, which is why the rule of thumb is to go with the 1st Dimm slot & pair with the matching slots tab color

Ryan said it in one sentence, bench in 1/2, then try 1/3 or 2/4 > I suspect if 1/2 is 'wrong', CPU-Z would say single channel mode, but it may not. The proof is in the benchmark pudding to break the tie between the factory look, Ryan & the manual > Report back

The picture in the manual is where I think the misunderstandings are originating.  The labels in this photo do not agree with the labels silk-screened onto the motherboard.  Look for yourself.  Those are, going from left (near the CPU) to right, 3,1,4,2.  I tend to trust these. Therefore page 76 is giving you what appears to be the wrong information, but if you follow the table, you are actually doing the right thing - two sets of errors cancelling out.  Could the tech writers get any more screwed up?  By following the table to use what the photo calls 1 and 2, I was actually using 3 and 1.  Which explains why my memtest speed was good. hooboy!

 Show & Tell: let's see a dang picture of your G.Diddy stuff, is it red / grey / blu, what

I got the Black / Red Kit

I enabled XMP through the BIOS settings (not AW OC app).  I would enable XMP1 (only option) - it seemed to ignore it and come up 2133Mhz.  I also tried XMP + OC1 & OC2 preset profiles.  It would either still fall back to 2133Mhz OR would not post (flash orange).

Are you doing all of this through the OC app?  Does it work on cold boot?

Garthman, may I suggest returning the BIOS setting you changed to default and using the OC page to set up a profile with 4.6 GHz cpu speed and memory as XMP1.  This should verify OK.  What memory speed shows?

The Ripjaws appear solid.  But in my 5 GHz profile, I did have to adjust the cpu voltage slightly upward after changing memory to get a cold boot without BSOD.  Note my previous message about the service manual errors.  the correct two sockets should be those to the left, closest to the cpu.   

On another note, I looked at the R7 cooling.  No name is visible on the cooler head, but I see the cpu and main fans are 140mm, so I think a binned and de-lidded cpu (post-warranty) should not require a bigger cooler to give max speed unless one wants to go exotic.
