mr_scary Posted January 20, 2017 Share Posted January 20, 2017 So I have this kit - 16GB 4x4GB CMK16GX4M4B3000C15 I purchased it for my X99 FTW board with 5930k XMP profile 3000MZ will change the base clock to 125.00 but if I run it at 3200MHZ it leaves the base clock alone. My question: Is it OK to run this kit at 3200MHZ without voiding the warranty. otherwise it will run at 2666MHZ.. I also have the 2666MHZ kit as well... If it's not advised to run the 3000-kit at 3200 then it goes back into the Z170 rig, I will just run the 2666-kit in the X99... Thanks for any replies...

xclock Posted January 20, 2017 Share Posted January 20, 2017 I don't even think it will even run at 3000mhz speed. this all depend on memory controller. did you try to run its rated speed yet? Link to comment Share on other sites More sharing options...
mr_scary Posted January 20, 2017 Author Share Posted January 20, 2017 Yes, it runs at 3000, but it changes the base clock to 125 which also increases voltage on the CPU. My temps go up 7c. Which is why it should run at 2666 or 3200. To keep the base clock at 100 stock. However it will not run at 2800 as far as I know. Link to comment Share on other sites More sharing options...
red-ray Posted January 20, 2017 Share Posted January 20, 2017 What is the SPD data? Post the [sPD] panel from my SIV utility. Link to comment Share on other sites More sharing options...
xclock Posted January 20, 2017 Share Posted January 20, 2017 did you try to run at 3200 with its rated volts?? you might just need to tune timings tho. Link to comment Share on other sites More sharing options...
c-attack Posted January 20, 2017 Share Posted January 20, 2017 In the early days on the platform and with DDR4, many of the X99 boards had BIOS instructions to jump up to the 125 strap or BCLK with memory speeds above 2666. Much of that was phased out in time, although it seems it remains on your BIOS from EVGA. It is up to them what the BCLK does. It is not the XMP preset per se that triggers the bump, but any time the memory frequency crosses or is equal to predefined values. 125 is a more natural multiplier fit for both the 2800 and 3000 frequencies. 100 for 3200. It may be the board has been programmed for just that. When it changes to 125, it changes all of your values affected by base clock. Multipliers for CPU and memory. The board is more likely to default to a standard state than try to keep whatever your timings were before. You must check everything. Also note the 125 strap will preclude using adaptive voltage. The better solution would be to not use XMP. It is just a time saving device. The "P" means preset and nothing more. If you have to adjust 10 other BIOS values, it is not saving you time. I would manually enter your 4 primary timings, set the speed you want, leave the BCLK at 100, and set DRAM voltage to 1.35. The board will do the rest. My guess is your board can run 3000 at 100 without any difficulty. Things have improved greatly since the board was launched 2+ years ago. Link to comment Share on other sites More sharing options...

Post the [sPD] panel from my SIV utility.I can get a snapshot from CPUz, but took the ram out, so I can do this later. did you try to run at 3200 with its rated volts?? you might just need to tune timings tho.Yes it runs at 3200MHZ just fine at rated volts 1.35 using the XMP In the early days on the platform and with DDR4, many of the X99 boards had BIOS instructions to jump up to the 125 strap or BCLK with memory speeds above 2666.

Things have improved greatly since the board was launched 2+ years ago.I was planning on doing this, but I don't want to risk loosing my raid 0. even though I have double BIOS. I don't want to have to reset and cause my raid to go bonkers. I will more then likely do it. I've manually setup ram in the past. but 3000MHZ for some reason I'm not liking. But it seems like something I will try anyway just for the sake of it. But really if it's ok to run at 3200MHZ I would rather do that. because I have the 2666MHZ kit that runs fine using XMP Link to comment Share on other sites More sharing options...
red-ray Posted January 20, 2017 Share Posted January 20, 2017 I can get a snapshot from CPUz, but took the ram out, so I can do this later. I did not ask for a CPUZ profile as CPUZ only provides the fastest XMP profile and SIV provides all the XMP profiles, so the CPUZ screen shot would be of little use.

When I install it back to the X99 I will do this if needed. Otherwise here is the summary from the Z170. http://williamwendland.com/wp-content/uploads/2017/01/spd2.jpg Link to comment Share on other sites More sharing options...
red-ray Posted January 20, 2017 Share Posted January 20, 2017 The SPD/XMP will be the same on all systems. XMP 6 is 1400MHz clock (2800MHz data rate) so try setting 14-16-16-33-49 timings + 1.35 volts manually and see what happens to the strap. Link to comment Share on other sites More sharing options...
mr_scary Posted January 20, 2017 Author Share Posted January 20, 2017 Uefi reports no change on the bclk 1.352 ram 14-16-16-33-49 @2134MHZ 2800/3000 is not available in the frequency list Link to comment Share on other sites More sharing options...
