Intel solved this issue with BIOS Version 0515. Thanks to Intel!

Re: DX79SI maybe wrong voltage on memory slots

webadmin@intel.com — Thu, 31 May 2012 09:00:59 GMT

Thank you for that answer.

Im using Intel products for more then 25 years. As usually, the social media support for products is nearly useless. Instead of commenting the misleading/wrong voltage displays in the BIOS configurations of your DX79SI, (maybe have a look at your products) Intel scares customers for using the products.

The Kingston KHX1600C9D3K2/8GX clearly requests a voltage of 1,65 Volts at DDR3-1600 MHz in the memory module specification, so this is no overclocking, anything runs inside specifications. Rising the voltage to 1,6625 Volts is just the attempt to make this board stable. As the BIOS unequally displays the voltage for the 4 channels and 8 slots, there maybe an error in BIOS. This issue clearly doesn´t mean anything "overclocked" devices or parts, just a plain error on the boards firmware/bios. Additionally this may lead to memory instability and freezing errors. To muddy the waters further... there is the reasonable suspicion, that the 8 memory slots are not provided with the same/configured voltages, even if the bios configuration states it and because there are different screens which displays different voltage values, which may lead to misleading assumptions.

Any more comments of "warranty loose" for processor or other devices available? If yes... i will return the board to the dealer and go for another product, because you are so undoubtful with your products.

Thank you.

Thank you for that answer,

but i cant imagine, that DX79SI doesn´t comply to the AHCI specifications, which should clearly

allow SATA (not ESATA) HOTPLUG. For my thoughts this is clearly an error in BIOS, so the HOTPLUG

configuration sections are missing there. So this is a job for INTEL to complete the BIOS at this edge.

Thank you!

DX79SI maybe wrong voltage on memory slots

webadmin@intel.com — Mon, 14 May 2012 08:38:35 GMT

I have a Intel DX79Si with the latest Bios (494). All memory slots are populated with 4 GB RAM dimms. For stability i

decided to rise the standard voltage from 1,65 Volts to 1,6625 Volts with Bios configuration utility for all channels and proved

it with success. That seems to work, and the Intel Extreme Tuning Utility shows 1,6625 Volts but doesn´t distinguish between channels.

But looking at the memory voltage values in Bios (not the configuration page), they are unequal, one Channel

is shown at 1,65 Volts the other at 1,6625 Volts, although there are 4 channels.

There must be a error in the Bios to display wrong values or the channels are not set to the same voltage.

Any ideas?

Thank you!

DX79SI doesn´t recognize hotpluged SATA Drive

I have a DX79SI with the latest BIOS (Vers 494). When i hotplug a SATA Drive to one of the SATA connectors, Windows 7 /64 does not recognize it

as hotplug drive. Even on searching for new devices in device manager, there is no success. I need to reboot Windows to make it visible, after that i can hotswap it out with no problems, but not hotplug it again. I have a known good SATA Hotplug tray solution which works on other boards. There are some hints that it is possible to configure this Hotplug/Hotswap in BIOS; but DX79SI Bios does not have such an option. I also played around with various device drivers ( windows 7 and intel chipset 9.2.3.1022). All Sata connectors are set to AHCI in BIOS. The Intel RST Driver is not installed.

Any ideas?

Thanks!

Re: Intel RAID RS2BL040 CacheCade performance problems

webadmin@intel.com — Wed, 14 Mar 2012 09:44:43 GMT

Thank you for the analysis,

as for 2012 there is a new SSD Feature Key for chache 2.0. It should do read and write chache at once.

Does it deliver better results as for chache 1.0?

Is there any suggestion on how many SSD´s and which size should be used ?

What happens in case of a power outage without bbu?

What happens if there is a SSD error ?

Should the SSD´s be in a mirror configuration? Is there a konfiguration option for mirror ssd´s on the raid controlles ?

For a low cost environment- is it ok to use an Intel 520 SSD with 120 GB? It should deliver about 550 MB/s on a 6 Gb/s sata connector.

Thank you for a fast answer.

Re: DX79SI & 8GB x 8 mem

There is news for the INTEL 3930K Prozessor. Intel stated 64 GB RAM now on the specification.

Re: Renesis USB3 is flaky on DX79SI, adding USB3 can be tricky

webadmin@intel.com — Wed, 14 Mar 2012 10:06:08 GMT

I found similar problems to that. I use a DX79SI/3930K under W7/64bit. Some problems

are gone with the latest Bios update ( vers 430) but the driver for the Renesas USB3 ports

is unusable leaving the ports useless. The driver causes W7 hang on boot or causes BSODs

on shutdown. I tried several suggestions mentioned here in the community but nothing

worked longer then 10 minutes.

INTEL: please debug those silly Renesas USB3 drivers!

Another point is, that the BIOS on startup takes about 30-40 seconds to go over the "5A" state.

I use an additonal Intel RS2BL080 Raid Controller, but the bios is so slow on startup.

Hoping for better drivers.

I would like to say, that not the harddisks are incompatible, but the controller is incompatible to disks. If this situation is ongoing, i will

change to another brand and product. I use raid controllers since 20 years, never had such an issue with lots of different harddisks. if there is a defect disk, i need to change to the next harddisk available, if that is not possibl,e i wouldn't use it for any valuable data. The raid controller should handle every standard or SAS Disk available. This is not an reliable product.

Re: Intel Web Raid Console is eating up Processor Power

webadmin@intel.com — Mon, 18 Jul 2011 06:30:18 GMT

As far as i know, there is no solution yet. They may seel more proz, if the software is eating up cycles ....
