Overclockers Crank World-Record Speeds out of Skylake Core i7-6700K

Two renowned overclockers have pushed Intel’s Core i7-6700K CPU to its absolute limit, breaking the world record in the process. The German pair, Der8auer and Dancop, overclocked the retail Skylake processor to hit 7007.85MHz, using an ASUS ROG Maximus VIII Gene motherboard and 2x4GB G.Skill DDR4 RAM, TechFrag reports.

The validated data, submitted to CPU-Z, shows that the Germans raised the multiplier to 69x, using a base clock frequency of 101.56MHz, while the overclocking was achieved using only one of the CPU’s four cores enabled and an uncore frequency of 2438MHz.

The overclocking yielded 4.8GHz using air cooling, but, when they implemented -190oC cooling, managed to raise speeds up to 7007.85MHz.

The overclocking is a new world record, breaking the previous score of 6998.88MHz achieved by Chi-Kui Lam.

Gigabyte BRIX GB-BXi5H-5200 Review


Today we are taking a look at Gigabyte’s Intel i5 5200U powered BRIX. Gigabyte has an impressive array of BRIX models that come in at all different performance levels with many CPU options and even options with discrete GPUs. The small form factor computer business has been exploding the last few years due in part with parts shrinking and their abilities skyrocketing. Many people have been buying small form factor units deciding to use them as business or daily workstations due to the low power consumption, helping to lower costs. Others love these small boxes for use as home theater PCs (HTPCs) since they can be tucked out of the way and will generally not be heard over ambient sound in the home theater. The specs for this BRIX look promising for use in both situations so let’s take a closer look and see just how well it would perform in these tasks.

  • Name: Gigabyte BRIX GB-BXi5H-5200
  • CPU: Intel i5 5200U (2C/4T, 2.2 GHz w/ 2.7 GHz Max Turbo, 14nm, 15W)
  • RAM: User Supplied – We tested with Crucial Ballistix 2x4GB DDR3-1600 9-9-9-24 1T 1.35v 
  • SSD: User Supplied – Crucial MX200 SSD 250GB
  • GPU: Integrated – Intel® HD Graphics 5500
  • LAN: Realtek RTL8111G 10/100/1000/Gigabit Base T
  • WLAN: 802.11a/b/g/n/ac Built-in Bluetooth V4.0
  • I/O: 4x USB3.0, 1x HDMI, 1x Mini isplayPort, Headphone-out, Microphone in, RJ-45/GbE LAN
  • OS: Supplied Barebones, Windows 10 preview used in this review
  • Warranty: 1 Year
  • Price: $364.99

Retail Packaging

Printed materials and hardware that the BRIX comes with. You will get a power adapter and power cord to hook up the BRIX as well as all the screws that you will need to mount your SSD or HDD and use the VESA mount if you wish. The DVD and printed materials are toss away materials in my opinion since the most up to date drivers and materials can be downloaded from the support website.



Windows 8 RTC Bug Fix Discovered

Christian Ney over at OCaholic has discovered the root cause of the Windows 8 RTC bug that led HWBot to ban all Windows 8 submissions. In collaboration with CPU-Z author Franck Delattre it was discovered that overclocking plays havoc with the four internal system timers. ACPI, HPET, RTC, and QPC are the four main timers on the system but the RTC and QPC timers go a bit crazy when the bus frequency is changed using a Windows based program.

That same problem does not happen when the frequency is set using the system BIOS and the system is made to boot from the changed frequency. The testing therefore infers that Windows 8 doesn’t use ACPI or HPET but instead a different internal timer. The bug doesn’t appear to affect AMD systems but under some circumstances it can. Based on the findings a bug fix is now available, which has to be applied using a command line setting. If there was some way for CPU-Z to represent if the bug-fix has been applied then HWBot could review its Windows 8 submission policy to allow Windows 8 submissions again.

The conclusions from Christian Ney’s research are as follows:

  • Windows 8 benchmarking results cannot be trusted since it is very easy to fool the RTC.
  • AMD can be affected too.
  • Windows 7 doesn’t have this issue unless somebody know how to make the RTC use the same timer source as the QPC. In other words use the DMI as source.
  • Windows 8 is the only one to blame here as the RTC is set to use the same timer source as the QPC and this one fails to use an external hardware timer source on Intel platforms and use the DMI frequency instead due to missing/faulty BCD parameter.
  • To fix it: run cmd as admin and paste “bcdedit /set {current} useplatformclock Yes”

Enthusiasts Rejoice: CPU-Z Now Available On Android

While there have been many unofficial versions or equivalents of CPU-Z available on Android for some time, CPUID have finally gotten around to releasing their official Android version of the popular desktop PC hardware information tool. The aim of the software is the same as it is on the desktop “a small tool that shows the key hardware feature of your device” and as you can see from the above screen shot it does do exactly that.

The key features are an ability to analyse your SoC, that is the CPU and GPU, and the system, namely the OS, RAM, circuit board and internal storage. There are also some more advanced information tabs on the sensors and the battery but these are just little extras.

CPUID have stated that CPU-Z for Android is currently only in beta stages and is at version 1.01. The app is totally free, just 193K in size, so far has an average rating of 4.8 and it is compatible with Android 3.0 and upwards.So if you’re interested in checking out the specifications of your Android phone then we recommend you give it a download from the Google Play Store here.

Ivy Bridge-E Xeon processor’s CPU-Z Validation spotted

The Ivy Bridge E processor has been speculated for release later this year in Q3 and will be replacing the currently Sandy Bridge-E lineup. A CPU-Z validation of an Intel Xeon processor with the code name Ivy Bridge-EP/EX said to be originating from China was spotted recently.

There’s no information other then the CPU-Z Validation, but it does give some idea of what kind of Ivy Bridge-E Xeon processor we could get to see. There is a model version mentioned on the CPU-Z Validation screenshot, but the processor with a stock clock of 1.6GHz, was seen to be overclocked to 2GHz.  The processor features 8 Cores and 20MB L3 cache.
