spikespiegel Posted June 23, 2017 Posted June 23, 2017 (edited) Hi guys, I have a ASROCK z270 mother board (LGA1151) (https://www.newegg.com/Product/Product.aspx?Item=N82E16813157739) with a i7 7700k. I have the following ram (64gb) (https://www.newegg.com/Product/Product.aspx?Item=N82E16820232264) . According to CPUZ, I am acheiving DRAM Frequency of 1076mhz tops. Even with XMP profile loaded, and showing DDR3400, should this speed not be around 1700mhz? No matter what I'm trying, its stuck at 1076mhz. I have even tried halfing my memory to 32gb thinking it couldnt' push that speed on 64gb.. But still no dice. I have ensured to use slot Slot 1/3 for dual channel. Can anyone please advise why I can't reach DDR3400 speeds? BTW in motherboard, under the DRAM settings, It keeps showing a 1:8 ratio when I select DDR3400. BTW, i'm on the latest bios. Thanks fellas! https://drive.google.com/file/d/0B7-sdB241gsVWnNOQlo5LUozalk/view?usp=sharing (PS see pic for the 1:8 DDR-2133 that keeps popping up no matter what) Edited June 23, 2017 by spikespiegel Share this post Link to post Share on other sites More sharing options...
ir_cow Posted June 23, 2017 Posted June 23, 2017 Are you seeing 2133 in software like CPU-Z or only in the BIOS? From the picture it looks like 3400 is loaded up and ready to go. If windows still shows 2133 than you might want to manually try 3200 or 3400 and see if it works. Share this post Link to post Share on other sites More sharing options...
spikespiegel Posted June 23, 2017 Posted June 23, 2017 yeah i'm trying to manually set it but no matter what i'm stuck on 1076mhz (via CPUZ) Share this post Link to post Share on other sites More sharing options...
ir_cow Posted June 23, 2017 Posted June 23, 2017 You are looking a the Memory tab right not the SPD? Share this post Link to post Share on other sites More sharing options...
ir_cow Posted June 23, 2017 Posted June 23, 2017 Unless the motherboard is clearing the settings, I can't think of why it would do this. I could see 3400 not working and defaulting the BIOS, but something like 2800 or 3000 shouldn't be pushing it that far. Share this post Link to post Share on other sites More sharing options...
ccokeman Posted June 24, 2017 Posted June 24, 2017 You should be able to go into the BIOS and set the XMP profile. Then manually set the voltage and see what you get. You may have to tune some of the voltages since not all chips are going to get there with just setting XMP settings. Share this post Link to post Share on other sites More sharing options...
spikespiegel Posted June 24, 2017 Posted June 24, 2017 Thanks guys. Whenever i do set the speed manually or at XMP profile , I keep seeing this 1:8 ratio keeping it down at DDR2133 speeds: See here: https://drive.google.com/file/d/0B7-sdB241gsVWnNOQlo5LUozalk/view?usp=sharing No matter what I do, it won't change from that speed.. I'll try and set the voltage manually,b ut what should I set it at? Default is 1.35.. Should I go higher? This is really bugging me!!

spikespiegel Posted June 24, 2017 Posted June 24, 2017 now that i'm messing with this mobo more, even stepping up the BCKL to 115 shows a target speed of 4800mhz, but in windows, it shows 4500mhz as max.. WHAT is going on with this Mobo!?? Share this post Link to post Share on other sites More sharing options...
ccokeman Posted June 24, 2017 Posted June 24, 2017 Reset everything in the bios to default settings. Reflash the most current BIOS again and do a full power down and remove the power cord. Hit the power button to discharge the caps in the PSU. Wait for a minute them go into the bios and set factory defaults. Reboot and go back into the BIOS and set the XMP profile. There may be one or two profiles you can choose from. Apply the settings and reboot. Does your BIOS allow you to save full images by hitting F12 with a flash drive inserted? That will give us a full image rather than the targeted image you uploaded. Share this post Link to post Share on other sites More sharing options...
