Title: Boot Loop on B75m-HD3
Post by: tacoeater on June 04, 2013, 05:48:39 am

Hi there,

I just got my new B75m-HD3 ordered from amazon, however this mobo will automatically reboot my machine before I can reach BIOS (less than 5-7 seconds mostly, sometimes even shorter). I used another mobo (ASRock H67m-iTX) to test out all of my other hardwares and they all just work fine. Any ideas?

My hardware (installed while the boot loop persists)
CPU: Intel E3-1230 v2 with original Intel CPU cooler
Memory: one Kingston HyperX KHX1600C9D3K2/8GX
Power: Seasonic X 460

Anyway to fix it? Or I would ask amazon to replace for another one.

Thanks.

Hi,

I view this infos:

Intel® Xeon® Processor E3-1230 v2 (8M Cache, 3.30 GHz)
http://ark.intel.com/products/65732

Intel® B75 Express Chipset
http://ark.intel.com/products/64030/Intel-BD82B75-PCH

I do not understand why you have this CPU model if the chipset does not have the same technical characteristics (advanced technologies) of CPU.

Why do not choose this chipset:
Intel® Q77 Express Chipset
http://www.intel.com/content/www/us/en/chipsets/business-chipsets/q77-express-chipset.html

And this mobo, by exemple:
GA-Q77M-D2H (rev. 1.0)
http://www.gigabyte.com/products/product-page.aspx?pid=4237#sp


==============================================
GA-B75M-HD3 (rev. 1.0)
http://www.gigabyte.com/products/product-page.aspx?pid=4389#sp

Kingston HyperX KHX1600C9D3K2/8GX
http://www.kingston.com/dataSheets/KHX1600C9D3K2_8GX.pdf

Otherwise,

Have you make a Clear CMOS?
And if you are able to go BIOS,
Make a Load Optimized Defaults
Reboot after

And return in Bios for make a change to:

In Bios have you able to change a timing, in SPD section, for:
DDR3-1600 at a low latency timing of 9-9-9-27 at 1.65V or 1.5v if possible...

NOTE for A-S-U-S:
Check this model:
www.a-s-u-s.com/Motherboards/P8B_WS (support Xeon processor)

======================================
Technical points to check, in the BIOS of mobo, if you want  the compatible VT-D IO :
I take for exemple : GA-Q67M-D2H-B3 and GA-Z68MX-UD2H-B3 (But Gigabyte said cannot support Xeon processor )


Intel IGD SWSCI OpRegion
DVMT Mode Select
Selects DVMT Mode used by Internal Graphics Device.
DVMT/FIXED Memory
Selects DVMT/FIXED Mode Memory size used by Internal Graphics Device.
Intel TXT(LT) Configuration
Intel TXT support only can be enabled/disabled if SMX is enabled. VT and VT-d Support must also be enabled prior to TXT.

I don't view setting for SMX (But Support must also be enabled prior to VT and VT-d)
What means SMX? (Safer Mode Extensions, i thiks)
VT and VT-d (Support must also be enabled prior to TXT).

And this mobo have a LAN Intel 82579 chip (10/100/1000 Mbit) ? Yes or No ?

Why this motherboard are not parameters for enabled-disabled VT and VT-D ?
What is the logic for develop other parameters like sub-section : Intel IGD SWSCI OpRegion?

Hi,

I don't know what "advanced technology"  is (just looked into wiki, but still not fully understand). What I want is just an high C/P value,  i7-like processor without HD3000, so I picked this one.  It is compatible with this mobo (http://www.cpu-upgrade.com/mb-Gigabyte/GA-B75M-HD3(rev._1.0).html) so why not? There's tons of success examples with similar build, especially for hackintosh.

So, the problem is I can't even get into BIOS (with HD Radeon 6850) because the system up time is so short. I tried CMOS reset, unplug power cord, remove battery, but none of them work.

BTW I have an i3-2100 on my shelf. I tested this one (I believe my ram won't run at 1600MHz) and the problem was still there. Anyway, seems someone else also had the same problem (http://www.wiki-qa.com/computers-accessories/computer-components/gigabyte-intel-b75-dual-uefi-matx-motherboard-ga-b75m-d3p-byarnulfo-navarrete.html), I'll just replace another one and see how it goes.

Have you tried with just the onboard video? So you can check what bios version you have.

Hi,

Just got a new board from Amazon. Everything works fine now. I think I just got a faulty board.

Good news for us...  ;)

I hope to you, the computer feel good....
