我一次测试一个RAM模块，甚至购买了不同品牌的RAM
CORSAIR CMSX32GX4M2A2400C16 Vengeance 32GB（2x16GB）260针DDR4 SO-DIMM DDR4 2400（PC4 19200）内存

嗨nik729我不太确定你是否设法在它被拉动之前瞥见这个nuc的兼容内存列表，但是hyperx和2400s的2x 16gb配置的海盗船将无法使用这个nuc。
您是否曾在2100年以较低的时钟速度尝试过它，并且还使用单杆配置。



以下为原文

Hi nik729 i am not too sure if you managed to catch a glimpse of the compatible memory list for this nuc before it was pulled but both hyperx and the corsair with 2x 16gb config at 2400 will not work with this nuc. Have you tried it at a lower clock speed at 2100 and also with a single stick configuration.

NUC8i7BEH下没有列出内存模块
http://compatibleproducts.intel.com/ProductDetails/ExportPeripheralInfo?moduleName=Intel%C2%AE%20NUC&productType=Kits&pr...
我认为你正在寻找下一代NUC7i7BNH
http://compatibleproducts.intel.com/ProductDetails/ExportPeripheralInfo?moduleName=Intel%C2%AE%20NUC&productType=Kits&pr...
根据NUC8i7BEH的系统内存页面：
内存要求
支持两个1.2V DDR4 SO-DIMM2400 MHz无缓冲，非ECCS单面或双面最小推荐内存：2 GB最大内存：32 GBSerial在线检测（SPD）
就像我之前说的那样，系统是稳定的，只是奇怪的是DRAM频率会发生变化



以下为原文

There are no memory modules listed under the NUC8i7BEH yet
http://compatibleproducts.intel.com/ProductDetails/ExportPeripheralInfo?moduleName=Intel%C2%AE%20NUC&productType=Kits&pr…
 
I think you were looking under last generations NUC7i7BNH
http://compatibleproducts.intel.com/ProductDetails/ExportPeripheralInfo?moduleName=Intel%C2%AE%20NUC&productType=Kits&pr…
 
 
Per the system Memory Page for the NUC8i7BEH:
Memory requirements

• Supports two 1.2V DDR4 SO-DIMMs
  
• 2400 MHz
  
• Unbuffered, non-ECC
  
• Single-sided or double-sided
  
• Minimum recommended memory: 2 GB
  
• Maximum memory: 32 GB
  
• Serial presence detect (SPD)
  

 
Like I have said before, the system is stable it is just weird about the DRAM frequency that changes

你读过我之前提到过的吗？
在过去一周左右，BEH删除了兼容英特尔验证的内存列表



以下为原文

Did you read what i mentioned before? the memory list of compatible intel verified was removed this last week or so for the BEH

不，我没有看到内存列表被删除之前。
我很想看看它。
此时我仍然可以返回金士顿公羊但是想在购买之前看到兼容的公羊名单。



以下为原文

No, I did not see the memory list before it was taken down.  I would love to take a look at it.  I could still return the Kingston Ram at this point but would like to see the compatible ram list before buying anymore.

我的亚马逊搜索历史中只有3个，当时我为列表中包含的系统定价ram
MTA16ATF1G64HZ-2G1A1微米8gb
M471A2K43BB1-CRC samsung 2400 16gb
HMA82GS6MFR8N-TF sk 2100 16gb
在16gb列表中没有海盗船或超级游戏



以下为原文

only 3 from my amazon search history when i was pricing up ram for the system that was included on the list
 
MTA16ATF1G64HZ-2G1A1 micron 8gb
M471A2K43BB1-CRC samsung 2400 16gb
HMA82GS6MFR8N-TF sk 2100 16gb
 
there were no corsair or hyperx on the 16gb list

英特尔兼容性列表显示已经过英特尔验证的兼容产品。
如果未列出类似产品，则并不意味着它们无法正常工作，只是尚未经过验证。
一个明显的例子是NVMe SSD的列表，他们只测试了英特尔自己的产品，但有很多竞争对手。
我手里有970 EVO，效果很好。
我安装了NUC8i7BEH和金士顿Hyper X Impact 2400 16gb。
我看到你在原帖中指出的内存时钟频率信息相同。
我无法解释为什么CPU-Z以它的方式显示频率，但我认为它正在报告它。
我可以告诉你，我已经在我的NUC上运行了Geekbench 4和UserBenchmark，其结果非常好，包括内存性能。
今天跑这个http://www.userbenchmark.com/UserRun/11227993
如果您继续使用Geekbench并查看我们的NUC的i7-8559U结果，并与Macbook Pro进行比较，您可以看到NUC的表现同样出色。
比较您的结果，让您高枕无忧。



以下为原文

The Intel compatibility list shows products that have been validated by Intel to be compatible. If similar products aren't listed it doesn't mean they won't work properly they just haven't been validated to do so.
A glaring example is the list of NVMe SSD's, they only tested Intel's own products, but there are plenty of competitors. I have a 970 EVO in mine and it works great.
I have a NUC8i7BEH with Kingston Hyper X Impact 2400 16gb installed. I see the same memory clock frequency info you pointed out in your original post.
I can't explain why CPU-Z shows the frequency the way it does but I think it's reporting it properly.
I can tell you that I have run Geekbench 4 and UserBenchmark on my NUC with great results including memory performance.
Ran this today http://www.userbenchmark.com/UserRun/11227993
If you go on Geekbench and look at i7-8559U results for our NUC's and compare with the Macbook Pro you can see that the NUC's perform just as well. Compare your results to give you peace of mind.

单个超级内存芯片的工作方式不同于两个。
我之前在一篇文章中提到尝试过一个芯片，因为两个芯片配置可能无法正常工作。
在以前的gen中，当您尝试32gb配置时，ram nucs使用非常挑剔



以下为原文

a single hyper memory chip will work differently than two. i did mention in a post earlier on to try one chip as two chip configuration may not work. In the previous gens the ram nucs use is extremely picky when you try 32gb configs

我有两个金士顿Hyper X Impact 2400 8gb ram主板，看起来我可能只有一个16gb，就像我写上一篇文章一样。
对于nik729来说，测试他当前的设置性能以确认ram是否有问题非常重要。
关于ram频率的这个CPU-Z问题是一个老问题，不太可能表示ram性能有任何问题。



以下为原文

I have two Kingston Hyper X Impact 2400 8gb ram boards, looks like I might have had only one 16gb the way I wrote my last post.
It's important for nik729 to test his current setup performance to confirm if ram is a problem or not.
This CPU-Z question on ram frequency is an old question and not likely to signify any problem with ram performance.

我有两个金士顿Hyper X Impact 2400 16gb ram主板，无论它们是否一起使用，每个单独或甚至在主板插槽上交换它都是相同的DRAM频率变化。
我也最终买了
Corsair16GB 2400MHzCMSX32GX4M2A2400C16
英特尔已验证，已在现已重新发布的英特尔产品兼容性列表中。
将两个16GB的Corsair棒放入，导致完全相同的DRAM波动，如我在金士顿RAM的原始帖子中所述。
我今晚跑了Geekbench：英特尔（R）客户端系统NUC8i7BEH - Geekbench浏览器
这个也是我之前的一点：英特尔（R）客户端系统NUC8i7BEH - Geekbench浏览器
和Usermark今晚：http：//www.userbenchmark.com/UserRun/11239006
一切顺利，所以谁知道。
性能很棒，一切都很稳定。
当我在最初的工作台标记和看东西时看到CPU-Z时，我碰巧碰到了它，但是否则不会知道任何异常并且没有正确运行



以下为原文

I have two Kingston Hyper X Impact 2400 16gb ram boards and whether they are used together, each individually or even swapped on the motherboard slots it is the same DRAM frequency changes.  I also ended up buying

Corsair

16GB 2400MHz

CMSX32GX4M2A2400C16

Intel Validated

which is on the now republished Intel Product Compatibility List. Putting both of the 16GB Corsair sticks in resulted in the exact same DRAM fluctuations as noted in my original post with the Kingston RAM.
 
I ran Geekbench tonight: Intel(R) Client Systems NUC8i7BEH - Geekbench Browser
This one is also me from a bit ago: Intel(R) Client Systems NUC8i7BEH - Geekbench Browser
and Usermark tonight: http://www.userbenchmark.com/UserRun/11239006
 
 
Everything runs smooth so who knows.  Performance is great, everything is stable.  I just happened to run across it when looking at CPU-Z when I was originally bench marking and looking at stuff but otherwise would not have known anything was abnormal and not running correctly

nik729，
我认为你原来的问题是有效的。
很高兴看到来自英特尔的人加入并解释我们所看到的内容。
我昨天正在研究这个ram clock问题。
论坛上有人说，如果CPU-Z上显示的ram频率与安装的ram不匹配，那么ram要么没有手动设置，要么通过XMP设置。
通过匹配，我的意思是它是ram频率的一半，即2400 Mhz ram的1200。
我注意到在CPU-Z Memory选项卡上，当Dram频率从665变为1198时，所有ras和cas值都会发生变化。
在dram freq 1200中，我看到的ras和cas值被设置为制造商指定的ram板值。
我们的NUC使用XMP 2.0，XMP使用ram板的SPD值来设置ras和cas。
在dram freq的665 ras和cas值不根据XMP配置文件设置。
Ras和cas值随着ram频率而变化，我看到的值看起来适合较低的频率。
如果XMP被关闭并且ras和cas值被设置并且手动锁定为1200 Mhz，那么在性能上是否存在差异将会很有趣。
但我不认为可以在我们拥有的Bios中完成。
我想知道当ram需求低时，我们看到的较低时钟是否是一种节省电力的方法。
如果是，那么从较低的时钟切换到1200会有一个小的时间延迟，这可能会影响性能。
感谢您发布基准测试结果，您的NUC运行状况略好于我的。



以下为原文

nik729,
 
I think your original question is a valid one. It would be nice to see someone from Intel chime in and explain what we're seeing. I was researching this ram clock issue yesterday. Somebody on a forum said that if the ram frequency shown on CPU-Z doesn't match the ram installed then the ram is either not setup properly manually or via XMP. By match I mean it's half of the ram's frequency i.e. 1200 for 2400 Mhz ram.
 
I noticed on CPU-Z Memory tab, when the Dram frequency goes from 665 to 1198 all of the ras and cas values below it change as well.
 
At dram freq of 1200 the ras and cas values I see displayed are set to the manufacturers specified values for the ram board. Our NUC's use XMP 2.0, XMP uses SPD values from the ram board to set the ras and cas.
 
At dram freq of 665 ras and cas values are not set according to XMP profile. Ras and cas values change with the ram frequency and the values I see look appropriate for the lower frequency.
 
It would be interesting to see if there would be a difference in performance if XMP was turned off and ras and cas values were set and locked for 1200 Mhz manually. But I don't think that can be done in the Bios we have.
 
I wonder if the lower clock we see is a way to save power when ram has a low demand. If it is, then there is going to be a small time delay from lower clock switch to 1200 which could possible affect performance.
 
Thanks for posting your benchmark results, your NUC is running slightly better than mine.

感谢您阐明我原帖的意图。
我同意如果英特尔的某个人能够确认它是按照预期执行，这是一个很好的错误，可以通过BIOS更新修复（通过XMP锁定SPD值或允许手动设置），或者可能是
与系统有关的缺陷。



以下为原文

Thanks for articulating the intent of my original post.
 
I agree it would be nice if someone from Intel could confirm that it is performing as intended, is a bug that can be fixed with a BIOS update (either locking in SPD values through XMP or allowing for manual settings), or is it possibly a defect that is more concerning with the system.

大家好，谢谢大家的反馈。
非常感谢。我想补充说，上述行为是预期的。

嗨nik729和大家，
我为英特尔客户支持工作，我一直在监控这个帖子，说实话，我没什么好说的，我不知道CPU-Z *做所有不同计算的方式，我去了他们的网站
环顾四周寻找更多细节，但我找不到任何与NB频率有关的东西，这似乎是北桥频率，我也没有得到DRAM频率，我的理解是它衡量每个周期的性能。
不幸的是，没有更好的方法来测量精确和精确的基本时钟（BCLK）速度，这就是你看到波动的原因。
记住BCLK在主板上驱动很多东西，从系统RAM到CPU以及PCIE设备。
考虑到这一点，我测试了4个不同的NUCS，它们都表现相似（所有这些都有DRAM频率波动），我也测试了几个第三方笔记本电脑，它们的行为方式相同。
如果您遇到系统不稳定等问题，请告诉我，但我认为这种行为是正常的。
我将进行更多的挖掘，但此时我无法做出任何承诺。
问候，
罗尼G.



以下为原文

Hi nik729 and everyone,
 
I work for Intel Customer Support and I have been monitoring this thread, I don’t have much to say to be honest with you, I am not aware of the way CPU-Z* does all the different calculation and I went to their website to look around for more details but I couldn’t find anything related to NB Frequency which seems to be North Bridge Frequency and I got nothing for DRAM Frequency either, my understanding is that it measures performance per every cycle. Unfortunately there's no better method how to measure the exact and precise Base Clock (BCLK) speed, so that's why you see fluctuations. Remember BCLK drivers a lot of things on the motherboards, from system RAM to the CPU and also PCIE devices. With that in mind, I tested 4 different NUCS and they all behave similar (all of them had DRAM Frequency fluctuations) and I also tested a couple of third party laptops and they behave the same way.
 
If you are experiencing issues such as system unstable, please let me know but I think this behavior is normal.
 
I will be doing some more digging but I cant promise anything at this point.
 
Regards,
Ronny G
