Announced on Dec 3rd, just a week ago, Google Public DNS service is still in testing/beta phase, so no SLA is available, but I’ve decided to give it a try. Google Public DNS uses Anycast to connect you to the closest DNS server, which in my case happens to be at ~42 msec away. Which is better than OpenDNS one at ~55 msec, but worse than Level 3 DNS 4.2.2.2 at ~36 msec. Right now I am using both Google Public DNS servers 8.8.8.8 and 8.8.4.4 as forwarders to see if any change in end-user experience would be noticeble. Will see.

How To Upgrade Windows 7 RC To RTM? Check out the following article after the jump. Tested, and working just fine minutes ago. Just one side note: when prompted to download setup updates, chose not to do that…

Tired from all those commercial SMS games you receive now and then from your mobile operator?! Happily if you are on Mobiltel AD, just send text “stop 500″ to 17867:

Edit: 500 is the name/code of the specific game. To stop others send their name/code.

As I said I shall have any news about ATI Radeon HD 4770, I wouldn’t knew I will have to play with two of those. That’s right, I have setup two 4770 in cross-fire mode, but that’s not all of it – as a bonus a brand new AMD Phenom X2 II 550 BE is under the hood, bringing a huge increase of speed and cache compared to AMD 7750 BE (from 2MB to 6 MB L3 cache).
Check out the screenshot above. You can click on image to expand it. All is done on air-cooling. The CPU is OC from 3100 to 3511 MHz (+13.2%) without raising the voltage! And 4770 OC is quite limited by Catalyst Control Center from 750/800 to 800/850 MHz (+6%) which is nothing at all. The real potential of those cards is like 850/1100 MHz. To be continued…

I just posted a comment in Picasa Web Albums in Bulgarian, and it was automatically translated in English. Good work, Google!

So is CUDA doing anything? You bet. There’s a 35% drop in output time with GPU acceleration enabled, so CUDA is plainly throwing everything it can at the job. But here’s the interesting part: AMD and Nvidia show essentially the same encode time in CPU-only mode, but Stream yields a 108% performance gain, easily trouncing the CUDA result while averaging 40% less CPU utilization than CUDA (read more).

I woke up, feeling like some Overclocking should be done today, so I fired my rig’s Power button and started few tools to help me out. The result is my AMD cpu OC from 2700 to 3200 MHz (+18.5%), and my ATI 3870 video card OC from 775/1125 to 837/1215 MHz (+8%). The latest could seems to be not a big deal, but it really helps gaming, I am sure.
Check out the screenshot above. You can click on image to expand it. Now, the Crysis64.exe is calling me…

Edit: Note that CPU OC is using stock voltage of 1.25V. By increasing it to 1.45V you can easily reach 3400 MHz. Quite impressive on air cooling. As for ATI 3870 OC, expect some interesting news next week when I will do ATI 4770 Crossfire testing, so until then.

I came across a very nice tool which could be quite handy when you upgrade your PC. Check it out:

Double Driver is a very simple and useful tool which not only allows you to view all the drivers installed on your system but also allows you to backup, restore, save and print all chosen drivers simply and reliably.

Hi there! I just completed my Intel rig and loaded it with Mac OS 10.5.5 without any issues. Now, that is a GUI (Graphical User Interface) and that’s how it should be done. Also I can tell you it starts in 10 seconds, and shuts-down in 5! Compare that with Windows Vista and you’ll definitely see the difference! I love BSD, so I’m going back to Mac OS exploration…

Finally I decided to move from Windows XP SP3 to Windows Vista 64-bit, mostly due to fact that I’ve got 8GB of memory, and XP only sees 3.2 of them! Now, I had to chose 64-bit Vista to achieve this, which leaded me to another pitfall which I shall discuss another time.

What I’m speaking now is that I immediately noticed one major difference in OS behaviour – Vista is using my hard disk drive almost all the time. I assume its doing some indexing or defragmenting, or some optimization, but it’s really annoying! I had to stop it.

Here are the Windows services which I stoped and put in Manual startup mode:

• Windows Defender*
• Tablet PC Input Service
• Superfetch
• ReadyBoost
• Application Experience

After doing that my Vista installation behaves as a regular XP one – my hard disk stays cool and quite. A side note: I have disabled Windows Defender from its Options settings before stopping it, and I’m doing so because I have better antivirus and anti-spyware solution installed.
