Re: Memory problems with new DZ77BH-55K

webadmin@intel.com — Sun, 13 Jan 2013 11:20:12 GMT

The memory settings continue to be buggy, the only way I've got my memory to work at 1600 (4x4) is to do the following:

Reset the BIOS to defaults (important to reset to defaults) and reboot back into the BIOS

Go to Advanced in the Visual BIOS, go to Memory settings page. Use the overclock slider and move it once to the right until you see the memory speed change to 1600. What ever you do, do not move it up or down again as this confuses things. Check the voltage, I think this memory should be rated 1.5 volt, so above the slider change the voltage to 1.5 volt. To the right make a note of the various memory settings/timings it has set, these should automatically be correct based on the SPD timings. DO NOT change these, I found changing anything here corrupted the memory settings, and even if setting back to the original settings I still got 3 beeps at boot time until the BIOS was reset to defaults.

Press F10 and save changes and reboot and see how that goes.

Unfortunately Intel boards (certainly the newest ones) seem to have very buggy BIOS's.

Re: DZ77BH-55K update to BIOS version BHZ7710H.86A.0083 caused major damage

You can download the 64bit EXE if that helps, the other files appear to not be available yet, either an error (links pointing to wrong location) or the files just haven't got around to being uploaded, perhaps due to the holidays.

Annoyingly while the BIOS appears to be working this new version has some annoying and unacceptable regressions.

1) The power light LED is constantly flashing again, this was fixed in BIOS version 94 so why has this come back Intel?

2) The dialogue that prompts for the hard-drive SATA password is now just a tiny square squashed in the top left hand corner, on previous BIOS's this only happened when graphics optimisation was checked in the BIOS, now it is happening all the time. So a bug made worse! Note, you can still type in the password for the SATA hard-drive, you just don't see a box to type into.

We also have a new boot screen graphic, can't notice any other changes except for more bugs.

My next motherboard WILL NOT be an Intel.

Re: Can Intel SRT (accelerate) + ReadyBoost be enabled concurrently?

webadmin@intel.com — Sat, 29 Dec 2012 12:37:21 GMT

There is no point in having both. The SSD cache is to speed up reads when you have a mechanical hard disk, and is could be considered a "poor man's" SSD. If you have an SSD in place of a hard disk you get zero benefit from the SSD cache, it might even hurt performance having an SSD cache with an SSD disk.

Re: NTFS compression increase write amplification?

webadmin@intel.com — Wed, 05 Dec 2012 18:17:42 GMT

In terms of write amplification it will be worse using NTFS compression if you use the extra space saved for more data. This is because the drive already compresses data before it is written but keeps it for itself. Some simple examples for a 240GByte hard drive.

No NTFS compression:

1) 240 GByte of data saved to SSD -> SSD compresses before writing -> Only 120GByte actually written to the SSD after compression. This leaves half the drive for wear levelling and other house keeping tasks.

With NTFS compression:

1) 240 Gbyte of data saved, compressed by PC CPU to 120GByte -> SSD tries to compress but can't compress much further, so 120 GByte written. This leaves 120GByte of usable free space. If the space isn't filled then you have the same wear levelling space as no NTFS compression, however if you then fill the 120GByte with data, you have no extra free space for wear levelling or other house keeping tasks.

So you have a trade off really, steel the space saved by compressing with NTFS and use the extra space for more storage, or let the SSD compress the data behind the scenes for the SSD's own benefit.

Overall depending on your usage the SSD will probably last as long as you need it to even using NTFS compression.

Re: No VT-d option with DZ77GA-70K and i7 2600k 3.4ghz procceser

webadmin@intel.com — Sun, 21 Oct 2012 20:41:29 GMT

The 2600K supports VT-x, but doesn't support VT-d. The tool doesn't appear to be making a distinction between the two.

Re: DZ77RE-75K ram question

webadmin@intel.com — Sun, 21 Oct 2012 16:26:35 GMT

For compatibility 1600 memory will always report itself as 1333, you need to manually tell most motherboards it is something different.

If you enter the visual BIOS, find the memory settings and move the overclocking slider to 1600, save the settings and reboot, now you should be running at the memories rated speed of 1600.

Note that Intel Desktop utilities usually will still report the memory running at 1333, however if you download cpu-z, under the memory tab it will show frequency ~800Mhz, which * 2 (for double data rate) is 1600.

The K (overclocking) versions of Intel CPU's do not usually support these features and the 2600K is one of those, you can see this on the product page here http://ark.intel.com/products/52214/Intel-Core-i7-2600K-Processor-8M-Cache-up-to-3_80-GHz

The flashing power light is something control by the BIOS, so it doesn't matter what the OS is.

Are you sure the flash was successful and you have updated to the latest version?

The flashing LED while was introduced a couple of firmwares ago, but definitely appears fixed in this latest version.

webadmin@intel.com — Fri, 19 Oct 2012 16:44:18 GMT

How odd, I've re-started my machine several times and the power light flashes for a couple of seconds while it starts then is steady.

Did you do a reset to defaults after updating?

Re: Intel Bios Engineers (DZ77BH-55K)

webadmin@intel.com — Thu, 18 Oct 2012 15:30:43 GMT

I updated by using the .BIO file on a USB stick in a USB 2 socket, no issues here, using an Intel SSD.

My steps are:

Reboot machine and start hitting F2 to enter the BIOS.
Do a reset to defaults (before attempting to update)
Save and Exit then as it reboots hit F7 to enter BIOS update screen
Select the USB drive and the BIO file and update the BIOS.
When it reboots after the update is complete, immediately hit F2 to get into the BIOS screen, another reset to defaults and reboot
Straight back into the BIOS and make the necessary setting changes I want

Also make sure options for UEFI secure boot or try UEFI boot first are disabled. By default the new BIOS seems to want to attempt a UEFI boot, and if that doesn't work it tries legacy. I'm not sure how reliable it is trying one and falling back to another.

Maybe that might help.
