I had the same issue you are having except I am running a Z170 Gaming K6. I had to manually set VCCIO and VCSSA manually to 1.10 and 1.15 respectively in order to run XMP 3200mhz. This combined with running a specific BIOS (version 2.10). Any other BIOS with the EXACT same settings results in instability. With that being said, if you are running the latest BIOS, try flashing back to an older one. I did this myself after finding that the latest BIOS for my board couldn't handle XMP 3200.
If nothing seems to work then I would consider RMA'ing the board. I highly doubt the CPU's IMC is the issue. Especially for a 'K' series chip, which is designed for overclocking.

well than at this point I'll probably let this issue drop. We simply wasted some money buying faster DDR4 ram but no big deal. Thank you to everyone for the help!

When it comes to gaming, it won't make much difference at all. Most builders recommend more slower RAM vs less faster RAM for gaming builds. More RAM means more buffering is possible so better performance (to a point).
Fast RAM is mostly only really useful for computational tasks and in the case of an APU or if you are using intel's iGPU for gaming. Integrated graphics solutions share RAM with the system so the faster it is the faster the iGPU performance. If you have a dedicated GPU however it uses it's own dedicated vRAM instead so the fast RAM makes very little difference. In fact I would be surprised if it makes more than a 1 - 2 FPS difference, even going from 2133 to 3000.

Thanks Xaltar, I just thought it was interesting since I don't have crossfire or anything odd turned on. I merely enabled my iGPU because I wanted to try to run dual monitors and it gave me another DVI connection. My dedicated video card only has one DVI. So that's how I discovered it by accident in the first place.
Now I'm curious to see what Wardog and Parsec say about the RAM speed 2133 vs 3000. If they feel running at 3000 will boost performance (FPS) even more than I will do whatever I can reasonably do, to make that happen.

In directx 12 titles yes, it's a really neat way to get some free FPS. If you are getting more FPS in DX 11 titles then I have no idea why that is happening, take it as a win  I would only be concerned if your GPU is under performing with the iGPU disabled and performing as intended with it enabled. You can easily determine that by looking at some reviews on the GPU in the games this is happening in. So long as your FPS are more or less in line with the review numbers (assuming similar system config) you should be fine. If the titles are DX 12 however then that is exactly what you should be seeing. Intel's iGPUs have come a long way, not quite AMD APU good but certainly enough to give you a little bit of a boost in FPS in DX 12 games.

Thank you both for the great replies. So I realize I messed up and didn't check the board compatibility matrix before I purchased my RAM. That was my bad. I can probably still send it back but from the sound of it, others even with approved RAM are still having similar issues.
So yes I have 2 sticks of RAM both 8g but here's the catch: I was building 2 gaming rigs and most info pointed to games only EVER needing 8g of RAM right now. So to save money, I split the 16g pair up and put 8 in mine and 8 in my girlfriend's computer. We each have just 1 stick (8G) in our A1 slot. Everything is working fine now with no issues for this past week. I understand we'd get better bandwidth if we had 2 sticks so I may buy another 16g set and then put this pair back together and add the new 16g pair to the other empty PC. For now let's assume I'm going to stick with solo 8g Sticks in the A1 slot on each of our PC's. I will try the settings that parsec mentioned but I believe the XMP setting was for 3066 speed and not 3000 which confused me a bit. I will take some photos tonight and post them to help make sure I'm trying to change the right settings. I am on the latest BIOS version and I am using the Advanced settings. For the record I was NOT trying to overclock as I don't know anything about overclocking really. I thought because my ram was 3000 speed that I could use this motherboard to take advantage of that speed RAM ...I didn't realize the only way was to overclock things. Showing my NEWBisness at overclocking. :( Again I guess I am still curious if this is even worth it at all? If I get it to operate at 3000 (which is highly unlikely) will it be much of a speed increase for all the trouble? -Maybe I just let things go the way they are with 2133 and call it a day. If you guys are like oh heck you'll see an 18% increase in performance on games, then sure I'll go for it. On a side note, I am using a GeForce GTX 1050 ti mini card. It runs great. I tried enabling the onboard video in the motherboard for the hell of it, and noticed my FPS increased in my games from around 60 to about 75. Is this an expected result? I was quite pleased with that little find so long as I'm not killing functionality in other areas that I might not realize.

You have a 8GB x2 kit of this memory? 16GB total? What UEFI/BIOS version do you currently have in your board? All Intel Skylake processors like yours are guaranteed to work at memory speeds up to 2133. Any speed above that is an over clock of the memory. Which DIMM slots are you using? 8GB or larger DIMMs should be used in the A1 and B1 slots. We can find the G.SKILL F4-2400C15D-16GVR version of your memory in your board's Memory Support list. But none of the higher speeds of the same model, "VR". As wardog pointed out, neither does G.SKILL include the F4-3000C15D-16GVR memory as compatible with your board. Click on the QVL tab on the page below: http://www.gskill.com/en/product/f4-3000c15d-16gvr We can try to get the memory working at a faster speed, but it is not a given that it will work at 3000. Yes, you were mistaken about simply changing the memory speed and the board automatically doing the rest. There is an option in the UEFI/BIOS to do that, called the Load XMP Setting, in the DRAM Configuration screen. Have you enabled the Load XMP Setting option? Among other things like the DRAM Voltage, VCCIO and VCCSA voltages, the memory speed will be set to 3000 when you enable the Load XMP Setting option. That is a start, although it is not guaranteed that your memory will work at the full 3000 speed. Next, in same DRAM Configuration screen, at the very bottom find the MRC Fast Boot option. Set it to Disabled. When you are done, go to the Save and Exit screen, and click on Save and Exit. All this assumes you are using the Advanced interface to your board's UEFI/BIOS. Is that what you use? If the PC does not boot, go back into the UEFI/BIOS, leave Load XMP Setting enabled, but just change the memory speed to 2400. Save and Exit again, and see what happens. You have a decent board, but a $100 board is not a high end over clocking board, which includes the CPU and memory. |

In my case this is a brand new build. New 500w power supply and running an I3-6100 chip. To answer your question I'm not running any CPU OC at the moment. I just let the motherboard at default settings.
I would need help in setting up my OC parameters as I am a complete NEWB to overclocking. I thought I'd just be able to set the RAM to a higher setting and let the motherboard bios do the rest. Apparently I was mistaken. The RAM works fine at the default 2133 setting. I will try to increase it by just 1 jump tonight and see what happens. If you can tell me what settings to configure manually I'm certainly willing to have a go at that as well.

For beginning, G.Skill doesn't certify that memory on your board which may or may not mean it will function as intended/designed. This particular kit is only, by G.Skill's own testing, certified to work on the outstanding Z170 OC Formula and comparable top end OC'ing boards from the other board manufacturers. Have you tried setting these sticks up manually in the BIOS? What CPU OC are you running? What parts does your system contain, and also how old is the PSU you're using. |
