AMD A10 7370K
Corsair Vengeance 4x8Gb memory DIMMs (straight off of ASUS' QVL) --- DDR3-1833

Win10Prox64

BIOS only recognizes half of the installed RAM.

MEM-OK checks (one DIMM at a time come back OK)

So, I have a MB with 32Gb of RAM, BIOS and Win10 claim 16Gb....

Any wisdom out there?

No cards, just AMD and memory on board. Never seen anything like this...

Thank you very much for your help. I appreciate it very much.

I have the "next to latest BIOS". A BIOS update was published last week. I have CROSSBLADE RANGER BIOS 1501 (11/11/2015)

DRAM Model# CMY16GX3M2A1866C9 (2x8Gb)=16Gb. I have 4 sticks @ 8Gb each for a total of 32Gb. BTW, that's Corsair Vengeance Pro Series. Had the DLd QVL with me at the retailer... LOL. Everything i could tell from that list vs. the package matched completely...

NO OC on APU.

Only thing "foreign" on the MB is memory. No graphics cars or ANY periphials...

I was getting a lot of BSODs with the original BIOS. 1502 all but eliminated that..

WIn10x64Pro has all updates per MS...

Couple of possibles, one is the DRAM just doesn't want to all play together (never a good idea to mix sets (even of the same exact model) no guarantees they will play together, more on this in my Fiction article - items 2 and 6, here:

http://www.tomshardware.com/reviews/ddr-dram-myths,4155.html

You can try raising the DRAM voltage + 0.05 and raise the CPU/NB voltage to 1.25 (it feeds your memory controller).

Another possible problem could be the CPU cooler is too tight in a corner or side throwing the MC off, can try loosening it and then snug down screw tight and try

fair enough. I'll get in there and see if I can up the voltages a bit, as you suggest.

The screws you are referring to--- those that hold the heat sink bracket to the MB? I seem to recall that those are 4 Phillips head, I believe.

Would you be willing to give me a little more detail about what setting(s) in the BIOS I am looking to change. I have found what I believe to be the correct ones.

Sorry, at this point, I am very shy about doing anything. This crossblade ranger has been BEYOND a nightmare for me. I am on MB#3 in 5 days.

Had 2 Rangers go nuts after BIOS updates, had to replace both, ASUS support told me to exchange the last 2. Now, can't see all the memory.

The other thing I notice in the BIOS is that what ever memory it IS finding, it is defaulting to 1333hz. Not sure if this is valuable info, or not.

Could this just be that ASUS just doesn't have their Win10x64 "stuff" together yet? I mean, my machine IS usable. It is seeing 16Gb (of 32),--- trying to take the minor victories here, for now.

The Ranger support site has a SMALL FRACTION of utilities and BIOS updates for Win10x64 than for, say, Win8.1x64. Seems like they are still chasing themselves with 10.

COuld this be ironed out over time with BIOS updates?

I must admit, my regard for ASUS is beginning to wane a bit.

Memory for A10-7870K is DDR3-2133MHz.

Your hardware is multiple sets of memory. Mixing together multiple sets of memory is not guaranteed to work because it often causes compatibility problems.

Vengeance Pro Series — 32GB (4 x 8GB) DDR3 DRAM 2133MHz C11 Memory Kit (CMY32GX3M4A2133C11)
This is a 32GB set.
http://www.corsair.com/en-us/vengeance-pro-series-32gb-4-x-8gb-ddr3-dram-2133mhz-c11-memory-kit-cmy32gx3m4a2133c11

If you look at the tech specs for this memory. You will see SPD ratings:
SPD Latency 9-9-9-24
SPD Speed 1333MHz
SPD Voltage 1.5V

Serial presence detect (SPD) is a standardized way to automatically access information about a computer memory module. That is what the memory runs at until the user sets the BIOS options manually or enables a XMP profile (eXtreme Memory Profile). XMP settings will enable the memory to run at its rated specifications.
• DDR3 2133
• Timing 11-11-11-27
• Cas Latency 11
• Voltage 1.5V

BIOS setting for memory: (PAGE 3-8 of manual)

You can use DOCP Dram OverClock Profile which will set a single memory kit to XMP ratings. It also may overclock other things such as CPU.

The other option is to set the AI Overclock Tuner to [Manual].
Then set Memory Frequency (page 3-9)
Then set DRAM Timing Control (page3-9 and 3-10)
Starting with Cas# Latency set the first 4 numbers
For memory I listed above:
• DDR3 2133
• Timing 11-11-11-27
• Cas Latency 11
• Voltage 1.5V
DRAM Voltage by default is 1.5v

OK, sounds like I need to change my memory...

I also have, on hand, 4 8Gb sticks of EVGA 16G-D3-2133-MR (ASUS told me they would not work as they were not on the QVL (smh) ) :sarcastic:

Now, the EVGA is NOT on the QVL, would that be worth trying with updating the BIOS as you recommend?

http://www.evga.com/Products/Product.aspx?pn=16G-D3-2133-MR

Memory Type: DDR3
Memory Size (Total): 16GB
Number of Modules: 2 (2x8GB)
Clockspeed: 2133 MHz
Timings: 11-11-11-31
Voltage: 1.6V
Channels: Dual
XMP Support: 1.3

Would this be worth trying?

BTW, THANK YOU! :)

Try enabling DOCP if available and set to 1866, when first installed DRAM goes to the mobos default

AI Overclock Tuner

You can use DOCP (Dram OverClock Profile) which will set a single memory kit to XMP ratings. It also may overclock other things such as the APU.

The other option is to set the AI Overclock Tuner to [Manual].

Leaving on [Auto] will give you conservative SPD settings. (1333MHz)

-- ********** --

EVGA 16G-D3-2133-MR is another 16GB kit. As previously mentioned, mixing up kits together is not guaranteed to work and can cause compatibility problems.

Might be XMP on your mobo, if so try that. Can also increase the CPU/NB voltage to 1.3 or use XMP and manually raise the CL (CAS) by one, or can try OCing the APU a bit

Can also try the EVGA sticks, the QVL is simply a list of DRAM they had available and time to test with

OK, this is getting more interesting.

I installed 2 8Gb EVGA DIMMs (2133). I was able, via D.O.H.C. (picked Profile 1 of 2), as suggested above in several posts, to get the BIOS to recognize the full 16Gb od RAM, and it reports they are operating at 2133hz. Awesome.

Now the interesting part, to me.

If I install an additional 2 DIMMs, I cannot get Win10 to "see the RAM".

if I install the first TWO DIMMs as recommended in the manual, i.e. A2 and B2 slots, I only get 8Gb of RAM acknowledged. If I install the first two DIMMs in A1 and A2, I get the result I have now, 16gB @ 2133 with DOHC profile 1.

IF I install DIMMs 3 and 4 in the now remaining slots B1 and B2, no change, and they are not seen on the Main Page of BIOS.

HOWEVER, they ARE acknowledged on the Advanced Tweaker GPU.DIMM Post page. I.e. that page shows all four slots occupied by 8Gb of RAM for a total of 32Gb, but the main page will not acknowledge any more than the 16gB.

The good news: I have a stable system with 16gB of RAM @ 2133 via Main page of BIOS and Win10.

The unexplained news: Additional RAM is recognized as being in the slot via DIMM.Post, but NOT by Windows.

The bad news (lol): I am stumped as to where to go from here, or what is holding the second 16Gb "hostage".

Again, thank you for all of your help...Been doing some reading and learning here, and I am starting to learn and appreciate what going on little by little.

So it sees and uses the A slots but not the B slots, this is often the CPU cooler too tight in a corner or side, throwing the CPU out of level affecting the MC. as mentioned earlier - "Another possible problem could be the CPU cooler is too tight in a corner or side throwing the MC off, can try loosening it and then snug down screw tight and try" - have you tried that

No sir, haven't tried loosening up the CPU cooler.

Do you recommend loosening all 4 screws and "re tightening", or only two of them? If so, the DIMM slot side, or the, let's call it the external port side?

Please tell me I can do that w/o yanking the Precooler off. Always makes me nervous trying to gently remove the heat sink/cooler w/o pulling the APU out by its roots along with it. I feel like a cat that has consumed 8 of its nine lives with being on MB number 3 right this moment taking that processor/HS of and on....

Sounds like if the loosening protocol doesn't work, I am looking at yet another MB..... smh... I mean, if that isn't it, it would seem that something is wonky on the MB, correct?

EDIT:

I WILL say that it seemed that the precooler latched down darn tight on the APU.... OK, reread your post again. GOt it. Loosen cooler, and don't clamp it down like i'm trying to make the APU lose 7/8 of its existing thickness.

Sorry, it's late.

OK, tried loosening the CPU cooler.... and... no love.

Now, I can swap out the four cards at random into slots A and all of the DIMMs seem to work.

Now that I think about this, as I indicated, this is MB #3, the last two crashing and burning on BIOS updating and never POSTing after that.

Those two boards exhibited the same memory behavior, tho I didn't get to push to where I am now as they crashed and burned and never giving me that opportunity.

Again, with a loose cooler, as i add DIMMs 3 and 4, the do show up one at a time in GPU.DIMM Post, just not on the Main screen. Stuck at 16Gb.

Guess I'll try to "reach out and touch" ASUS tomorrow. Damn. ... that is unless you're not running out of knowlege//experience/magic as to what else to try.....

Get the two in slots 1-2 by the CPU running, go into BIOS and raise the DRAM voltage th e+0.05 as suggested earlier, then try the CPU/NB at 1.3, save exit shut down and add a third stick and try. If no joy it may well be that all the sticks just don't want to play - never a good idea to mix packages as no guarantee they will play

I will try that tomorrow. Got to head out the door by 0700 tomorrow.

I hear you ref mixing packages. I am learning that.

So, to get to 32Gb of RAM, you recommend a 4-pack of 8s, or 2 pack of 16s (if that even exists)?

Sorry, wasn't ignoring your recommendations (ref voltages). I just had to step thru little by little as I am learning.

I take it you, or Calvin7, like the Corsair CMY32GX3M4A2133C11 (?) as it was in one of the previous posts....

What vendor do you prefer/recommend ref memory?

Yes 4x8GB, it may cost a bit more than 2 sets or two sticks - but that's because it takes more time and testing to put together 4 sticks that will all play nice than it does two. You might pull ten sticks off the assembly line and might be able to match up a 4 stick set

OK....

so my gameplan is to order a 4 stick set, and, in the mean time, flash the latest BIOS, tweak voltages and see what happens.

Also, I am noticing that the Win10x64 BOIS updates are flowing readily for the ranger right now. The latest was released TODAY...

ASUS recommends updating to the latest BIOS (which makes sense). I guess I will do that and try the memory I have right now (who knows, may get lucky, but I kinda doubt it).

The saga continues, but I do feel that the light at the end of the tunnel is approaching...
