I have Asrock Extreme 3 LGA2011 X79 mobo. Regardless which memory chips I install I get horrible timings. According to CPU-Z the timings are: 29-27-13-55-887 instead of, for example, 11-11-11-28-39-312 (typical timings for JEDEC-1600MHz). I have tried everything: tried manual and auto values, tried XMP and default profiles, cleared CMOS and loaded BIOS defaults manually. When I boot into Windows 7 64-bit I get the same timings, they never change. I have tried Kingston HyperX and Mushkin memory modules, they both support 2400MHz, tried with 1 stick and 4 sticks. Even by default the timings are always the same. I reflashed BIOS (thou it was already the latest v 2.90). The mobo is in like new condition, no dust at all, I trust that it was never used before.
Am I so lucky to get a faulty mobo or is it just BIOS chip? Ah, remember another thing - the memory works at 1600MHz or at 1866MHz (doesnot matter if I set it manually to something above 1600MHz or switch on XMP). And in both cases the timings are still the same, they do never change. Searching Google gave no result. P.S. I am using Xeon E5-2660V2 CPU. |

Do this for me please.
Grab a screenshot of CPU-z's Memory Tab _AND_ one each of each sticks SPD Tabs. 5 Screenshots total. Post them here for me to view. |

Sorry, not sure how to attach photos here. However I have found where the problem was and suggest to close this thread. So, for the future reference be aware that CPU-Id is a bit buggy. I tried 2 other programs - Aida and HWInfo and they both showed me the correct values of timings. Everything is OK, the memory works like it should. I have used CPU-Id for many years and was confident in it. Looks like it is far from being 100% accurate. Thank you for your willingness to help.

hehe first you said you were using CPU-z. But turns out it was CPU-ID. Anyways, glad things are sorted there and all is as should be. |

CPU-Z has bugs reading DDR3 memory on an X79 system? I believe you, just stating how ridiculous that is, considering how long X79 systems have existed. I assume you are using the latest or a relatively new version? If so, maybe something was broken recently. Yes, we trust monitoring programs like CPU-Z, but maintaining them is not easy. Meaning they must be modified to work with a specific platform, and then even different boards within a platform. I've seen two recent (one current, Ver. 1.79.0 x64)) CPU-Z bugs when run on Ryzen systems. The previous version cannot read AMD Ryzen's RAID implementation, it would lock up during the detection phase and could not be killed with Task Manager. Might not be Ryzen compatible at all. The 1.79 version shows the Ryzen VCore on ASRock boards at twice the actual VCore. That of course scares users to death. They posted about it in this forum. One guy decided his ASRock Ryzen board killed his memory because of the high VCore. ![]() Yes it takes work to get this right, but most people believe CPU-Z first. Compare the Maximum VCore shown in HWiNFO to that of CPU-Z, exactly twice the value is shown in CPU-Z: ![]() |

Actually its the same program as I know. http://www.imageup.ru/img110/2765092/xeon-3.png Here is what CPU-Z showed (I used the latest version) http://www.imageup.ru/img110/2765093/xeon.png And here is info from HWINFO (AIDA shows the same) http://www.imageup.ru/img110/2765087/xeon-4.png Still can't post pictures here, get some error 500 ![]() Then another question. Cannot get memory to work at frequences higher than 1866MHz. Does this depend on the processor capability? Or is it the motherboard's limit? Btw, CPU-Z identified the CPU as Intel Xeon E5 2660 v2, when HWINFO shows Intel Xeon-2100. So, nobody's perfect ![]() Edited by Rusbear - 11 May 2017 at 7:36pm |

The memory spec of your Xeon CPU is 1866 max, and Xeons tend to be limited in their over clocking potential. Of course now you'll tell me your Xeon has unlocked core multipliers, as some Xeons do. You mentioned two brands of 2400 memory, Kingston HyperX and Mushkin, are you trying to use them together in the board, or individually? What are the model numbers and total size being used? Your board is rated for 2400 speed memory, which is an OC. If you enable the XMP profile for 2400, they then won't POST? You may need to increase the VCCSA and VTT voltages to get the memory at 2400. |

I took Kingston from another PC just for testing and wont be using anymore. Now I use 4x4Gb Mushkin Redline modules (rated PC3-19200 10-12-12-28 1.65v). So I enabled XMP in BIOS and booted in Windows. Everything worked fine except that the frequency was only 1866MHz (instead of 2400MHz) and timings were like they should be by XMP (10-12-12-28). I only reduced those timings manually to 9-10-10-26 and I am using this configuration currently.
I know that my Xeon is not overclockable (we are not talking about possible 5-6% increase in FSB). If I wanted to play with overclocking I would go with E5-1650 type of CPU and a better motherboard. I am more concerned about playing with 10 cores (20 threads), would like to see the difference with my previous Core-i5. And frankly speaking 1866MHz with good timings suits me fine. But since both the motherboard and the memory support 2400MHz, I would like to use this possibility. I have heard different opinions on that - some people say that CPU can restrict the frequency, some say that it can be motherboard related. So I will appreciate if anyone here can put some light on that. |
