Hi

i need help here like seriously I'm going mad and i don't know what do to do. recently i bought a i7 2600k and DP67DE motherboard everything was perfect till my hard drive decided to crash on me twice, After that i manage to get a new one so i reinstalled windows but then my power supply blew on me lucky it's still work but i noticed my cpu wasn't running as it used to be my game don't run smoothly as well as my software and wins rated my processor speed 5.9 it felt like i just downgraded back to a Pentium dual, Please i need answers i tried updates, formatting and forums and still nothing is there a possible when my power supply blew that my cpu got damaged too or is there a driver that's needed?

And if so what i should do...

Try Going into BIOS and set everything to default , run the machine again if that makes no change you may have overvolted the CPU , If thats the case I am suprized it works at all.

Download and run CPUz and see what info it gives you about volts being used and operating Frq.

If you go for a RMA do not mention the PSU.

Intel® Turbo Boost Technology

Intel has optimized Intel® Turbo Boost Technology¹ to provide even more performance when needed on the latest-generation http://www.intel.com/technology/architecture-silicon/2ndgen/index.htm?iid=tech_tb+arch Intel® microarchitecture code name Sandy Bridge. Intel® Turbo Boost Technology 2.0 automatically allows processor cores to run faster than the base operating frequency if it's operating below power, current, and temperature specification limits.

Intel Core i7-2600K

Specifications: 

Frequency: 3.4GHz

Core: Sandy Bridge

Manufacturing process: 32nm

Number of cores: 4 x physical, 4 x logical

Cache: L1: 64KB + 64KB (each core), L2: 512 KB (each core), L3: 8MB (shared)

Memory controller: Dual-channel DDR3, 1,333MHz

GPU: HD 3000

Packaging: LGA1155

Thermal Design Power (TDP): 95W

Features: SSE, SSE2, SSE3, SSSE3, SSE4, SSE4.2, EM64T, EIST, Execute Disable Bit, VT, AES-NI, Turbo Boost 2.0, AVX, Quick Sync Video

why is my i7 2600k slow?

So I have testing several computers now, with i7 2600k (3.4GHz)

In order to make a true comparison, both CPUs must be used in identical PCs, otherwise differences in the case and it's cooling ability, different hardware, and the programs used will cause the CPUs to be in different environments.

Otherwise if you simply changed CPUs in the same PC, there is a reason for the temperature differences between the i7-2600k and the i5-2500k. Although both of these CPUs are 95W TDP devices, and their standard clock and Turbo speeds are very close, the main difference between them is the i5-2500k does not have Hyper Threading. The i5-2500k is a 4C / 4T (4 Core / 4 Thread) CPU, while the i7-2600k is a 4C / 8T CPU. Having two threads running on a core is more work and stress put on the core, and it becomes warmer. If Hyper Threading is disabled (in the BIOS) on a CPU that has this feature, the CPU temperature will go down up to 10C under high usage/stress situations. Enthusiasts that over clock their CPUs will sometimes disable Hyper Threading in order to lower the CPU temperature that has increased due to their high over clock.

You can try this yourself if your BIOS allows you to disable Hyper Threading on your i7-2600k. The effect of doing that will be more noticeable during high CPU load situations, rather than at idle. So it is not a simple, straightforward situation that the i5-2500k has a lower default operating temperature than the i7-2600k. The Hyper Threading feature of the i7-2600k makes a significant difference.

Intel® Desktop Board 

DP67DETechnical Product Specification

http://downloadmirror.intel.com/19490/eng/DP67DE_TechProdSpec.pdf downloadmirror.intel.com/19490/eng/DP67DE_TechProdSpec.pdf

3 Overview of BIOS Features

3.1 Introduction

The board uses an Intel BIOS that is stored in the Serial Peripheral Interface Flash

Memory (SPI Flash) and can be updated using a disk-based program. The SPI Flash

contains the BIOS Setup program, POST, the PCI auto-configuration utility, LAN

EEPROM information, and Plug and Play support.

The BIOS displays a message during POST identifying the type of BIOS and a revision

code. The initial production BIOSs are identified as BAP6710H.86A.

When the BIOS Setup configuration jumper is set to configure mode and the computer

is powered-up, the BIOS compares the CPU version and the microcode version in the

BIOS and reports if the two match.

The BIOS Setup program can be used to view and change the BIOS settings for the

computer. The BIOS Setup program is accessed by pressing the key after the

Power-On Self-Test (POST) memory test begins and before the operating system boot

begins. The menu bar is shown below.

Maintenance Main Configuration Performance Security Power Boot Exit

Error Masages and Beep Codes

4.2 BIOS Beep Codes

Whenever a recoverable error occurs during POST, the BIOS causes the board's speaker to beep an error message describing the problem (see Table 39).

Table 39. BIOS Beep Codes

Type Pattern Frequency

F2 Setup / F10 Boot Menu 

Prompt 

One 0.5 second beep when BIOS is ready to accept keyboard input

932 Hz

BIOS update in progress None

Video error On-off (1.0 second each) two times, then 2.5-second pause (off), entire pattern repeats (beeps and pause) once and the BIOS will continue to boot.

932 Hz

When no VGA option ROM is found.

Memory error On-off (1.0 second each) three times, then 2.5-second pause (off), entire pattern repeats (beeps and pause) until the system is powered off.

932 Hz

Thermal trip warning Alternate high and low beeps (1.0 second each) for eight beeps, followed by system shut down.

High beep 2000 Hz

Low beep 1500 Hz

EXPLANATION

Check the BIOS is very important.

 

BIOS

settings back to the DEFAULT

 

Check the CPU operation voltage must be optimized,

CPU temperature is optimal,

normal work CPU operation and optimal

"normal clock speed"

 

"Processor must work properly"

Note: Do not for now overcloking processor in BOIS

I submitted the technical data of the Intel motherboard in PDF format

 

together with the Web site for the checking process, you must read Intel's instructions. In fact the slow working of the processor is not a big problem to remove it since it can not see a problem, I will be with you until it is fixed.

I would also sugest getting a good PSU Like a SeaSonic 850 gold cert. Prob. $ 150.00 to $180.00 depending on where you go , these second gen CPUs are Very dependant on accurate Volts especially when it come to turbo boost.

Well I have the same sort of problem, my turbo won't kick in when needed.

It clockes 3.4 and not faster when needed. even with a stresstest.

Also i found out that Corsair SSD's are not that compatible with this board.

If you can be more specific. I need information. Thanks

It is true that Corsair SSD currently has problems with Some Board because they are not compatible with SSD.

I believe that this will be resolved shortly.

For some board processor i7 2600k can not be overclocked to 3.4 Hz, because does not support Corsair SSD or can not withstand extreme working Intel i7 processors 2600k.

a few weeks a ago my psu blew but it was working fine also my board and cpu were working fine cause my psu had surge protection. But after my psu blew my system become sluggish like most my programmes would take long to run plus 3d max would lag a lot while loading and it never happened to me before so i downloaded a cpu meter and says my core 1 is running at 100% usage i did everything i un-installed unless programs and my anti virus it still says 100% usage. Even my friend who deals with computer couldn't figure it out we tried changing the bios to default it still lags I formatted 3 times and installed the drivers and checked before installing 3d max and etc and still nothing. is my motherboard or cpu damaged?

Moral of the story , Buy a real good PSU , Gold SEASONIC 850 Watt , and a Cyberpower 1500Watt UPS , and you can't go Wrong.

Remember PSU are connected with Hard disk as well as motherboards. So if something is happened as a result of PSU damage then the victim could be Hard disk also! Check if it runs slow even while playing files from CD-DVD also.If it persists then try checking the motherboard. I hope nothing has happened to your processor becoz it is not directly connected to the PSU

SUMMARY

=== Checking ===

 

= Power = right

 

= Motherboard = right

 

= CPU = correct

 

= Graphics = right

 

= Memory = right

Below are the instructions carefully =

Turn off the computer from the power supply to open the casing you can see the motherboard on the motherboard there is a small battery, remove the small batteryfor a few minutes, then the battery

 

gently back into the motherboard.

Computer-assemble, switch voltage,

 

initially raising the BOIS set time and date.

 

 

Your Intel products will work properly, because you made a mistake.
