Hi!
Just one word before: english isn't my native language, so please excuse bad grammar by me. Unfortunately online translators are way to back to translate readable stuff.
I have a load of problems with the board above since i bought it.
- Yes, of course the used psu is compatible.
- The used Kingston RAM worked like charme in different Sandy Bridge systems.
Yes, i am an experienced pc user and built systems since the Intel 80286 AT (NEAT) era.
The problems with the above board raised since updating the bios to the current version of 0152.
System Specification
====================
OS: Microsoft Windows 7 Pro (x86-64)
Mainboard: Intel DH87MC // BIOS 0152
CPU: Intel i7-4770
RAM: 2x Kingston Value RAM (KVR1333D3N9K2/8G), JEDEC standard
dGPU: NVIDIA GEForce GTX 760
PSU: Antec TruPower 550
Display: HP w2448hc (HDMI connected to iGPU / DVI connected to dGPU) - not using softwarecrap like Lucid.
Low Priority
====================
1. The written versions in the bios readme are inconsistent. The summary on top doesn't reflect the versions within the description of the online-manual (VBIOS, GOP) http://downloadmirror.intel.com/23454/eng/MC_0152_ReleaseNotes.pdf
Medium Priority (since BIOS 0152)
====================
1. Wrong memory temperature: The mainboard is talking about 108 °C degree of the memory, which is totally wrong.
2. Not working limits for CPU-, Inlet- and Outlet-Fans anymore on Auto-Mode (it worked before the bios upgrade - for now i have to live with manual setting).
Medium Priority (since beginning)
====================
1. Haswell i7-4770 isn't able to use 4x Kingston Value RAM (KVR1333D3N9K2/8G) anymore. Using 4 memory slots leads to blackscreens after power on, freezes and reboots. The rams are fine anyway, i can exchange 'em as i want: 2 are fine, 4 are not working. The Haswell memorycontroller is a pain!
The same memory part's worked like charme on all of my i5-2500K (DH67BL) and i3-2105 (DQ67OW, DH67CF) and i3-550 (DH55TC) systems.
2. Using Native PCIe ASPM OS Management in Virtual BIOS leads to an extremely instable system. Freezing while working (not easy to reproduce) and freezing after standby (reproducable every time) leads to a non working system. The psu is well enough - it happen's even with C6 disabled and unpopulated PCIe/PCI Slots.
The both bugs before were so annoying that i already was thinking about sending the cpu and mainboard back to the reseller. It tooks HOURS to get the system running, even with placing recoverymode jumpers there were no picture available with used 4 ram slots.
High Priority (since HD Graphics Driver 10.18.10.3345)
====================
This is a special one, not many people will experience it.
I have connected my HP w2448hc display twice with my system. Via HDMI to the Haswell iGPU 4600 (including audio) and via DVI to the GEForce GTX 760 (excluding audio).
I like the QuickSync Feature and the power of 3D applications. The Haswell 4600 is a good one, but not comparable to a GTX 760.
Before upgrading the HD Graphics driver i could switch on the display between iGPU and dGPU without any problem. The active GPU was the primary one and worked fine.
After upgrading the driver (even a clean un-(install) in windows-safe mode) this didn't worked errorfree anymore.
- If i start with HDMI (iGPU) selected:
System starts up fine, Intel HDMI Audio is available, dGPU is as extended part available - this is perfect.
- If i switch to DVI (dGPU):
dGPU (GEForce GTX 760) is now the primary one, Intel HD 4600 (and audio) are disabled - this is fine too.
- If i switch back to HDMI (iGPU):
Although iGPU Video is available, the Intel HDMI Audio is NOT available anymore. The devicemanager shows an exclamationmark. It can't be started until rebooting the whole machine again.
This worked errorfree on the previous driver. Unfortunately a driver rollback doesn't work anymore, even after a clean uninstall. The new driver has something changed in the os which i can not identify.
Btw., the same new driver makes problems on hdmi / dvi connections on DH67BL, DH67CF and DQ67OW machines too. Installing this driver leads to a blackscreen. Only solution ist to replug the connection cable between machine and display. A driver downgrade via windows-safeboot doesn't help here, because the new driver is changing something, what it should NOT do (perhaps BIOS? system drivers? registry?).
--------------------
To be honest, i am very disappointed with the lack of support of the new generation of mainboards. While the x6x productline was an example for high quality support, the x8x line is a complete different thing.
I've planned to replace all of the sandy bridge and clarkdale systems to a haswell based one (10 pc's - i love those machines and home theater pc's, server services etc.) - but with my experiences until now i will not buy a haswell (refresh) based system anymore. Way too much bugs and way to bad support and driver quality now. I never experienced this with intel products anytime before - this is nearly amd style. -.-
PS: I don't think we have to "reproduce" any steps after this clear description and can inform the engineers directly. Do you agree?
