It's in German, but the numbers in the table are universal, I guess.
In CPU bottlenecks the IPC was a good 10% higher for the 4670K vs the 3570K. In Starcraft 2 the very good result for Haswell could be explained by increased cache bandwidth, but that probably is a special case. ]]> CPUs and Overclocking boxleitnerb http://forums.anandtech.com/showthread.php?t=2321691 hdd is not working properly http://forums.anandtech.com/showthread.php?t=2321690&goto=newpost Sat, 25 May 2013 10:29:08 GMT

A disk read error occurred; Press Ctrl+Alt+Del to restart
"A disk read error occured" is displayed when the active partitions boot sector cannot read ntldr.

It can also be displayed if extended int13 calls are disabled in bios, ntldr is on a bad sector, FRS segment can't be loaded or any NTFS metadata is corrupt.

It's unlikely extended int13s are disabled. resetting bios to default would eliminate this.

The chain of events that leads you here follows. The last step is the one that fails, I'll let you troubleshoot from here.
1. Bios picks what disk to read based on the settings you give.
2. Bios reads and executes code in MBR at sector 0.
3. MBR checks partition table for which partition is active.
4. MBR loads the boot code at the active partition.
5. The boot code reads ntldr.

Step 5 is where the error is.
If ntldr were actually missing in step 5 you would get a missing ntldr message.
Step 2 & 4 must be working properly or we couldn't reach this point.

Check the settings for step 1 & 3 and you'll find your answer.

If they are both correct then you are back to the corruption I mentioned earlier. Chkdsk /R ftw.

Good Luck!

by c'g the above problem in my life now, here my problem is when i connect hdd and on bios is not opening , when i remove my hdd and on pc then my bios is opening , where d problem is ,

The NIC is on the shroud side of the 580, and the sound card is on the PCB side

I placed temperature probes, one in the gap between the 580 and the NIC and one inside the sound cards faux EMI shield.

I loaded the GPU to 100% with Metro 2033 and left it that way for over 20 minutes. The sound card side temp reached a maximum of ~50°C, while the NIC side probe reached closer to 60°C.

According to Intel, the max operating temperature for the nic should be 55°C, I'm not sure about the sound card.

Would you say that these cards are at any risk of premature failure if I run them next to the GTX 580 long term. ]]> Video Cards and Graphics Oubadah http://forums.anandtech.com/showthread.php?t=2321689 Apache Tuning -- ExtendedStatus http://forums.anandtech.com/showthread.php?t=2321688&goto=newpost Sat, 25 May 2013 10:18:56 GMT While reading through the Apache documentation, I found a mention that disabling ExtendedStatus can speed things up by preventing gettimeofday() calls.

While reading through the Apache documentation, I found a mention that disabling ExtendedStatus can speed things up by preventing gettimeofday() calls. I deal with a lot of servers that see a lot of traffic and wanted to find out what kind of gains it would give me. Strangely, I actually found that having ExtendedStatus enabled gave me lower times per strace o.O

I setup the Apache server to only have 1 process running which would serve 5000 requests. I then had another server run 5000 requests at a time to an index.html page that just said 'test'. Since I expected the time savings to be unnoticeable on the client side, I didn't use ab or siege... I just straced the Apache process and used the -T flag to print out the times for each call:

Code:

strace -T -s 500 -p `ps aux | grep httpd | grep apache | grep -v grep | awk '{print $2}'` -o time-noExtended-5000

After 25,000 traces each I got the following total times (minus 'accept()'):

Code:

time-Extended-5000.1: 47.9501

time-Extended-5000.2: 47.4915

time-Extended-5000.3: 47.2623

Total: 244.574

Avg/5K: 48.9149

Avg/Request: 0.00978297

There are an additional ~45,000 calls in each of the time-Extended files.

I've checked the time spent in each type of call, and with the exception of gettimeofday(), the noExtended spend more time in each call:

Sadly, when I manually compare two requests, I'm not seeing anything obvious and even finding that the noExtend ran faster.

Anyone know why this might be happening? Do I need more datapoints to make a good comparison? 25,000 seemed quite a bit to me, but I'm no statistician. ]]> *nix Software bobross419 http://forums.anandtech.com/showthread.php?t=2321688 Secure Folder Software with Dropbox http://forums.anandtech.com/showthread.php?t=2321686&goto=newpost Sat, 25 May 2013 08:37:12 GMT I am trying to find some software which will secure folders on our system (and be secure on dropbox), we will have about 250 folders (one for each user) each will need to have their own password... I am trying to find some software which will secure folders on our system (and be secure on dropbox), we will have about 250 folders (one for each user) each will need to have their own password protected folder.

I have been told about truecrypt but it is a lot of messing about having to mount drives for each user.

It has to be stupid proof and very easy to use as the people who will be in charge of it have limited IT knowledge.

Ideally what would be good is if a folder could be clicked on you enter a password and you have access then if you click another folder the first folder is locked and you have to enter another password to open the second folder.

Hope this makes sense.

On my Nexus 7 this does not happen. The navigation bar remains at the bottom of the screen. I would like it to mimic the phone's behaviour. Short of fiddling with dpi settings I haven't found out a way of altering this.

We've had several releases this year that rank very high in terms of graphical prowess, but how do they compare to the all time greats?

Yes, I intentionally used the phrase "best looking" because I didn't want this thread to focus purely on graphics tech, as art style is just as important when it comes to immersion.

My vote goes to Metro Last Light. It was a tough decision between it and Crysis 3, but in the end, I went with Metro LL because of not only it's inclusion of so many PC game technologies, ie PhysX, DX11, 3D Vision etcetera, but it's abundant use of them as well..

Metro Last Light also has the best weather effects I've ever seen in ANY game bar none..

I've tried to take into account everything I can think of but I still come up 120gb short out of the total 450gb. Maybe someone can thing of something I missed?

My OS is Windows 7 and my system disk is a 480gb Intel 520 SSD. It's formatted with the default partitions (MBR, 100mb system reserved, 447.01gb system partition).

According to Windows, the size of the partition is 447gb. 441gb is used, and 5.36 is free. According to Windows Explorer, the total size of all files and folders is 324gb, and their size on disk is 317gb. According to WinDirStat, the total size of all files and folders is 317gb. So this comes out to somewhere between 120gb and 130gb of space that's simply missing.

Here's what I've checked so far:
- Recycle Bin is empty
- I made sure to include all hidden files and systems files (like pagefile.sys) when totaling up the size of files and folders
- System Protection (shadow copy & system restore) is only using 1.55gb. (According to Windows anyways)
- chkdsk says that there are 0 bad sectors and no problems of any other kind.
- Intel SSD Toolbox reports no problems and 100% health for the SSD.
