SSD Intel 520 Reported running UMDA Mode 5 (ATA 100)

webadmin@intel.com — Thu, 26 Apr 2012 04:58:36 GMT

Specs:

Intel DZ68BC

i2600K

8 Gig (2x4) ram

Intel 120 Gig Series 520 SSD

Using the Intel Desktop Control Utility, under System Info-Details-Hard Drive; I see that the Max Transfer Mode is reported as UDMA 6 (ATA/133).

But the utility also reports that the Active Transfer Mode is actually UDMA 5 (ATA/100)

Is this normal? Should the active mode be UDMA 6 as well?

Thanks.

Edited to correctly identify the program used to see the transfer mode.

@ Steve and rseiler: I believe you will find that Sleep mode is available only after installation of Graphics Driver. I agree with vbaderks, BIOS settings. Several settings have strange or unexpected results. In the performance settings, setting to automatic, instead of manual changes operation sometimes, even if it appears that the individual settings are the same.

Intel recommends that you start with automatic, and then switch to manual for extra performance enhancement, but when I went from BIOS 0021 to 0028, mine was 'defaulted' to manual, I had problems with sleep mode and also with failure to shutdown. I found that changing to automatic fixed the problem, but I could not see what the difference was in the individual settings. I have experiemented with it a lot, and can not determine why this is so. On another board, I had problems with Processor C States, had to be disabled, but I see in your original post that you have already disabled it. Is it still disabled? Maybe try disableing it in conjunction with other changes.

Hi, this is going to be long, so bear with me!

I have had the same issues you describe along with shutdown problems, although my MOBO is a Z68, (DZ68BC to be exact). Sometimes would not wake, sometimes would wake system, but no video and occasionally would wake and reboot. Along with this, the system would often not shut down, well, actually it would shut down, but after a few seconds would restart on its own. I went through all the hoopla with tech support, blaming everything from memory to case, then I RMA the MOBO, and still have the same issues. Later I was ‘informed’ that the SSD was the problem, WRONG again, the problem was just more likely to occur with an SSD, it would still occur with HDD, just not as often. Use of USB 3 ports and drivers also complicated the issue; it would work somewhat more consistently with USB 3 disabled.... So, after considerable troubleshooting on my own, (many long hours) I have managed to find three solutions. One is just a work-around, another is an odd fix, and the last seems to actually cure the issues. Now, bear in mind this is with the Z68 series, but may apply to X79 as well.

1. Power Supply is an issue with some of the boards, but not all, either you get a good MOBO or you get one like the 2 that I have used. For some reason, some boards are only compatible with a certain few power supplies. In my case several (5) perfectly good power supplies that worked fine in any other system, would not work with this board, yet after trying several, I found a couple that would work just fine with regard to the sleep and shut down issues. Why this is I cannot determine, only speculate. (Tech Support at Intel tells me is normal!!!) It has never been normal for any builds I have ever done. These same Support people also insist that using memory rated to run 1600 caused damage to the on-chip memory controller, even though it was set to run at 1333??? They tell me to RMA my i7 processor. There is nothing worng with my processor.

2. Certain settings in BIOS, that seem totally unrelated to the issue, actually seem to fix the problems, or at least act as work around. I have found that if you disable 'Processor C States' under Power options in BIOS, the problem no longer exists, with most power supplies, (I am currently using a Seasonic M1211 620W Bronze certified model) and will work with most Atecs also.

Note: the more expensive Seasonic X650 Gold model will not even turn on the system, no matter what settings I try, and several Corsairs cause odd problems also.

If this helps your situation I have more on why I believe this works.

3. In the Z68 bios, under performance options, the default after BIOS flash is Manual, but if you change it to automatic, you can get the system to work no matter how you set the Processor C States, and with the USB 3 drivers loaded and ports enabled and using either a HHD or an SSD. So now, after many hours of troubleshooting, and parts swapping I have a very good working system. But , if I had to do over I would have to say it has been more of a hassle than it is worth. And I actually enjoy troubleshooting, just not for something that should have been produced in a more ‘complete’ working condition when purchased. If you search the forums you will find this problem occurring of people over and over.

Maybe these ‘fixes’ will help some people, even if it does not apply to the X79 you currently have.

Good Luck, and please post what your eventual fix turns out to be. This is a very interesting issue for me. I have invested a good amount of time in it!

Hello, I believe I am having a very similar issue.

I have been fighting this issue for nearly a month. the problem started out as a USB 3 issue, with the 3.0 driver installed the system would not shut down, actually it would, but would restart after 5 seconds?? I replaced the MOBO, memory, processor, and power supply. Nothing helped. Then I discovered that sleep mode was affected also, upon entering and exiting sleep the system would reboot. After trying everthing in the bios I found that if I disabled 'Processor C States' everything worked fine. Do't know why, but upon passing the information to another post in bleeping computer forums, someone with identical problem found that it cured his problem also.

But, I was still courious as to why this setting has to be disabled. So as to make a long story s hort, I found (after multiple parts replacement and changing 4 power supplies). that the problem was with the power supply. But all these supplies that did not work with the DZ68BC worked just fine in other systems. Now the power supply that did work was rather underpowered for the system so I have been trying various, well rated supplies, (seasonic 620 Bronze and Seasonic x650 Gold to be specific) The first one had the same problem, and the x650 will not even turn the system on, the lights flicker, the supply clicks a relay and nothing else, I have tried two of the X650 modles, They are very well rated, both have the same problem.

What I would like to know from anyone with this problem is just what quality supply will work with this board?? I need something around 600 watt or more. Any suggestions would be much appreciated.

Thanks in advance.
