Just a quick test run! Here is the code I ran:
I pulled a piezo speaker from an old desktop computer that I had. These things can run directly off the GPIO or you can add a resistor to lower the volume if necessary. I connected the speaker to pin GPIO18 (PWM) and GND.
I then used a modified version of the code presented here on the third post. I do not take any credit for writing this code.
What the poster did not mention was that “tone 60″ is equivalent to MIDI middle C. From there you can figure out what value most of the major notes are. Then you can create a little song by expanding upon that script which is what I have done. I did it line by line which is likely the laziest and most inefficient method. Instead an array could have been used or an input file to be parsed. You can also change the time length of each note but I just left most of them 0.1 seconds.
There are more efficient ways of doing it, but I was working with what I had for my first go at the GPIOs.
I get my GPIO breakout and breadboard this week, so I will play around more.
So after llano released I wanted to give it a shot but never got around to it. Now finally after so long I’m going back to it. (See previous posts for motherboard and CPU shots)
Picked up the Gigabyte A75-UD4H and 3870K for around $160CAD total so it couldnt hurt
I decided to do some preliminary CPU tests under cold air. For those of you that do not know, Llano does not clock nearly as well as Phenom II did on air. Max stable air clocks for my chip are around 3.5GHz on the corsair H50 so I’m using cold air to give a little bit more headroom for benchmarks.
About -10C outside currently.
Just did some quick and dirty chilled H2O runs with my corsair H50 on the 3870K. Corsair rad was put out the window in -10C weather.
Ram was left at a stock XMP profile, just overclocking with multiplier here. Untuned Win 7 X64
4.1GHz validation All 4 Cores………mm voltage
Thats all for tonight, the chip is back to folding for the time being.
When I get time to bench again, next up is some ram+GPU tuning and some 3d benchies vs stock benchies
Well amidst all the new releases of trinity and PD, I have opted to pick up a 3870K paired with a GA-75-UD4H to have a little bit of fun.
I skipped over llano when it came out and most other releases as I have been pretty busy with life outside the forums/blog.
So now it is time to make up for all that.
I will be receiving my 3870K in a week, but for now here are some shots of the board and ram:
This is the ram kit I have :
Hopefully this can provide enough bandwidth for the iGPU…especially once I tweak it
I will be posting results in here once I get the APU
I have recently been working on fixing my HP g6 laptop. As a result, everything is ripped apart down to the bare bone hardware itself.
That is when I started to get ideas. …
We all know that mobile llano (sabine) is capable of being software clocked using K10Stat. So I decided to bust out a lightweight dry ice pot and fill it with regular ice cubes!
Now for a couple fun little benchmark runs!
Well all I can say is that was fun. The laptop motherboard I am using actually has a broken connector for the LCD screen so I am waiting for a new one to ship. Maybe I can pick up a cheap A8-3500M and do some benching on that!

Hey everyone. This week I swapped out my GTX570 for a brand new 7950.
Why didn’t I get a 670 you ask? I felt like trying an AMD card this round and it was a great deal!
Here are the hardware pr0nz:
The “Excalibur” Box
Card is sitting neatly and cleanly wrapped in the package.
I have no idea what the black plastic thing is, but here is what comes in the box.
And now, the card in all it’s beauty (sorry for the lower quality pics).
As you can see above, this card takes two 6-pin PCIE power.
This card supports eyefinity, so you can have up to 6 monitors connected. You will also notice this card has 2 mini display-port as well as HDMI and DVI.
Benchmarks will come later on!
Did a build for my friend recently. He needed it for some gaming, specifically Diablo 3. It is a little overkill for that game, but it should last him for awhile. The Specs are:
Intel i5 3450 Ivy Bridge CPU
G.Skill Ripjaw 16GB
EVGA GTX570 SuperClocked GPU
Corsair CX600 PSU
1TB 7200.12 Seagate HDD
Antec One Case
Here are the pics:
Unfortunately I never got a chance to benchmark the Ivy since they needed the build right away. It is a non-unlocked chip so it won’t OC as easily or far either.
I just wanted to do a quick review of my brand new monitor: The Samsung SyncMaster S24B300 LED LCD
This 24″ LED LCD monitor is beautiful….really, it looks great. Here are the specs it is packing (From Samsung Site):
Here are a few sample pictures taken from my Galaxy Nexus. I also tossed in a few full screenshots of Diablo 3. These are not the best representation of the monitor, as you cannot see it up close for yourself….but this is easily the best monitor I have ever used.
The colours are very vibrant compared to other monitors. Images are sharp, and games and movies look amazing. It truly was a treat loading up a 1080P movie and watching it fullscreen. I don’t think I can ever watch any media less then 1080P HD ever again. The power and menu buttons on the bottom right of the bezel are touch which was nice. Keep in mind that I used to be on an old Dell 19″ 1280*1024 monitor, which I used for almost 4 years ( sad I know).
The only cons are the non-standard power connector (which shouldn’t be a problem unless you happen to lose the power cord) and the fact that the inputs have two options: HDMI, or VGA. There is no DVI or displayport on this monitor. I don’t see this as much of a downside since I had an HDMI cord laying around I could spare.
All in all if you are in the market, this is a wonderful monitor at a decent price. I paid $189 CAD for mine. If anyone has any questions about the monitor, or wants to see more/better pictures, just drop a comment
