OK, just installed a FM2A88X+Killer MB and have an interesting issue and am requesting insight/suggestions... System (all are new components "out of the box"): OS: Win10x64, latest updates installed MB: (see above) APU: AMD A10-7870K RAM: CORSAIR
Vengeance Pro 32GB (4 x 8GB) 240-Pin DDR3 SDRAM DDR3 2133 Desktop Memory Model
CMY32GX3M4A2133C11 (Silver) SSD: Samsung 850 Pro Series 256GB SATA III 6Gb/s 2.5" Internal Solid State Drive (SSD) MZ-7KE256BW PSU: Corsair CX750M ******************************** I have updated to the latest BIOS version for this MB via the BIOS update functionality. On the BIOS Main page, I am only able to get half of the RAM recognized (16Gb of 32Gb). I have DIMMs in all 4 slots. Main indicates A1: DDR3-2133 A2: DDR3-2133 Single channel memory mode. I have achieved the 2133 speed via an XMP profile. SO, what am I missing/what am I screwing up ref not getting all of the memory to be "seen"? BTW, I have no other peripherals on the MB--- APU, RAM Sticks, and that's it (!) (Minor) Issue 2: My machine will not restart completely. Win10 acts like it is shutting down, display goes black, monitor power goes off, and machine sits there powered up, but in a "no mans land". To continue with restart, I have to hit the restart button on the case, after which it reboots find. Any insight or wisdom is welcomed, and, thank you for your assistance in advance. ------------- GrumpyAeroGuy |

1. Grab CPU-z from the authors site http://www.cpuid.com/softwares/cpu-z.html" rel="nofollow - HERE 2. If CPU-z, in Windows, will recognize all four sticks, fire up multiple instances of CPU-z on your desktop and post for each stick/slot its "Memory" and "SPD" tabs. Too, did you set these manually or use their XMP Profiles to let the system/BIOS adjust them? |

 Accomplished via XMP Profile... ------------- GrumpyAeroGuy |

1. First, re-seat all four sticks of your memory. 2. Clear your CMOS via the Jumper method described in your manual. (EDIT: This will obviously remove any memory settings, ie: XMP Profile) Does the BIOS, after a clearing of the CMOS, recognize all four sticks at their JEDEC Default speed? If so, continue on to # 3 IF NOT, STOP HERE and post back. 3. I'm not sure this is possible w/o manually setting them vs using XMP, but change the Command Rate(CR) to 2 in the BIOS, Save and Exit, going right back into the BIOS to check the existence of your four sticks. 4. No go yet? Ok. Let's raise the CPU/NB Voltage just a touch and check the results in the BIOS. BIOS > OC Tweaker > Multiplier/Voltage Change (Set this to Manual) > CPU/NB Voltage (Bump this .05v) Then "Save and Exit", let reboot and go right back into the BIOS to check if all four sticks magically appear. If not, go back in and raise it another .05v(.10 TOTAL on two adjustments now) Save and Exit, then recheck again. Keep us informed please. |

Give me a bit, and I'll do that. EDIT: Does BIOS recognize all four sticks at their JEDEC Default speed..... DO you mean how much RAM is reported on the BIOS main page after this procedure of clearing CMOS?

Yes. In the BIOS only after you clear the CMOS, are the four sticks recognized while at their default JEDEC programming of, I'm guessing here 1333. |

1. Did it 2 Did it BIOS, on its main page is now/still recognizing 16Gb of the 32Gb, running at 1300 or some thing very low like that. Thus, the Clear CMOS was successful, as all of the XMP stuff I set is now reverted back. CPU-Z on the mem page reports 32, window reports 16 Thus, stopping here aand posting back as requested. ------------- GrumpyAeroGuy |

Are the two again showing up in in the BIOS as/in slots A1 and A2 as your original post here stated? |

Wife has me running to the store before the snow falls here in Michigan. Be back in 30mins. In the meantime, lets try something that's easily reversible. Go into the DRAM settings and if it's not already at a Command Rate(CR) of two change it/them to two and check. brb |

that's exactly what I'm doing..... LOL (in Ohio) except 2 snowflakes paralyze our city, as opposed to MI that knows what to do with it. be with you in 20-30 after trying your suggestions. ------------- GrumpyAeroGuy |

OK, they are recognized in single channel mode... A1 and A2 Interestingly, DRAM Manual control allows me to go between sticks 1-4, so the BIOS knows they are there. Not trying to be a bonehead, but I can't find the parameter you wanted me to change to 2 ------------- GrumpyAeroGuy |

OK, found CR, and ALL 4 DIMMs were AUTO, showing "2T". Went to manual, forced the issue to "2T" for all, and we're left with the same issue. (!) Main page shows 16Gb at 1333 Single Channel Mode. Now it's my turn, Boss wants to go run a few more errands with me, now that I ran the ones she wanted earlier. Just to rule this out, double checked that my OS was REALLY 64bit. It is: 64bit Win7x64. Bizarre. I guess this points to the memory or the processor---the processor seeming to be a very long shot here---there are NO OTHER SYMPTONS what so ever that would indicate the processor is operating any way but normal. Who'd'a thunk it would be this big a pain in the back of the front to get 4 sticks of memory recognized. I gave up the Crossblade Ranger in lieu of this MB (which I must say I am liking better) for the EXACT SAME ISSUE.... I am also wondering of this isn't a fail in/of Win10. Be back in a bit.... AND.... thank you very much for your interest and assistance.

We're dabbling in the BIOS, so ALL should be recognized. In the OS all might not be depending on just which ""64bit Win7x64"" you have. ie: Home, Pro, etc. Yea, she's got the Lodge skillet turning fresh grated potatoes into hash browns. See ya back here in a while. |

mmm, sounds good.... ************************** Update: Pulled 2 sticks amd set them aside. Put 2 sticks in A1/B1 and A2/B2 per manual. only 8 of 16Gb recognized in each case (!) Put 2 sticks in A1/A2, 16Gb recognized (!) Always resorts to single channel mode. Do I just have memory that don't like this MB, or vice versa? IT almost seems like the B-Bank isn't being allowed to "contribute". IF this does point to the memory, I guess I can try to swap it out with something else. I'll start looking at the QVL and see what options there are. Given this frustration, I AM fascinated to know what finally will work. I will look to see if there is a 2 stick 32Gb kit that is on the QVL. I am running Win10x64 Pro with the latest updates, using that term loosely as it IS microshaft. smh

OK, I am toying with doing a WIn10 Reset. Couldn't hurt. I have 2 additional HDDs both partitioned into 2 logical drives, and I do cyclic image backups across all of them. So, I won't lose anything. Just grasping at straws. ------------- GrumpyAeroGuy |

For dual channel to work, you need to have the modules in pairs. The manual instructs you to use A1/B1 or A2/B2, which tells you how the modules are paired. In other words, the modules you've put in A1/A2 are not paired and this is why the memory is in single channel mode. You could try putting those two sticks in B1/B2 just to test if the machine boots at all. ------------- Ryzen 5 1500X, ASRock AB350M Pro4, 2x8 GB G.Skill Trident Z 3466CL16, Sapphire Pulse RX Vega56 8G HBM2, Corsair RM550x, Samsung 960 EVO SSD (NVMe) 250GB, Samsung 850 EVO SSD 500 GB, Windows 10 64-bit |

BIG THANKS to @wardog for all of his help. After a lot of advice and guidance from wardog, troubleshooting, pointing, as well as some scratching, it turns out that I had 2 bent pins on my processor. Took me 5 minutes and a quite powerful magnifiying glass before I found them. One was in the corner, and one was exacly along the edge of the processor. Go figure. I tried to be very careful, but, somewhere, after taking this processor in and out numerous times, i did something that, to this day, I am not sure how I did it. As indicated, managed to bend two pins and hose it up. The minute I discovered that, and replaced the processor, the machine fired to life, recognized all of the RAM, allowed an immediate SPD overclock of the memory to 2133MHz, and is just purring like a proverbial kitten. Advice to others: My machine, other than this interesting "half of the RAM recognized" issue, was running fine and there was no other indication that anything was wrong what-so-ever. Please don't rule out a bent pin or two as causing some strange wierdness that otherwise would never seem to point to an APU. Lesson learned. So, to summarize, my system is blissfully happy configured as follows: AMD-A10-7870K (Godovari) G.Skill Sniper 32Gb (4x8GB), DDR3-2133 (PC3 17000), F3-2133C10Q-32GSR ASRock FM2A88X+Killer All works great together. Again, thanks to wardog for all of his patience and help. Happy computing/gaming! ------------- GrumpyAeroGuy |

Nice job, wardog! I'm glad to hear the problem is resolved, even though bent pins are never good news. ------------- Ryzen 5 1500X, ASRock AB350M Pro4, 2x8 GB G.Skill Trident Z 3466CL16, Sapphire Pulse RX Vega56 8G HBM2, Corsair RM550x, Samsung 960 EVO SSD (NVMe) 250GB, Samsung 850 EVO SSD 500 GB, Windows 10 64-bit |

In some instances it is much easier to press points over the phone rather than to ping pong our path through posting time consuming messages back and forth in forums. This was one of them. Ol' Grumpy isn't so Grumpy now  |
