GeForce GTX 580 - Fermi Done Right!

!±8± GeForce GTX 580 - Fermi Done Right!

This is simultaneously the best kept and the most talked about secret in the business right now. The GeForce GTX 580 - it's been rumored to be everything from dual GF104 chips to a new monster concoction of epic proportions. Just about all the rumors got it wrong until concrete evidence began to disseminate through the leaky pipes of the supply chain. Even then, as the specs began to bubble up to the surface, most people came to the wrong conclusions.

It all started back in the March/April time frame, around when NVIDIA launched their first part built on the well-hyped Fermi architecture, the GeForce GTX 480. Reviews were mixed; it was the fastest single GPU on the planet, no questions asked. It was a tessellation monster and its scaling in games, up to 3-way SLI, was incredible. It was a great advance for gaming computers.

But it was also hot and loud. And that was compounded by the press using open-air test beds to test the GeForce GTX 480 - which meant the card had to do all the work in moving air over its hot components without the assistance of a well-ventilated chassis.

In fact, it is proven that the heat-stack vertical design of the MAINGEAR SHIFT custom built pc aided the GeForce GTX 480 in such a way that it was dramatically quieter in 3-way SLI than an identically configured Corsair 800D chassis that has terrible airflow.

The GeForce GTX 580 is a fully-realized GF100 with all 512 shaders. It has higher memory bandwidth, and a higher core and shader clock. And it does all of this while drawing less power and at half the noise level. It's the last two features that will blindside everyone. Once the specs made it from the rumor department to accepted, on-line "fact," everyone began to speculate that it would sound like a hair dryer and draw the power generated by a flux capacitor. And require 1.21 jiggawatts and 88mph to go back in time.

In reality, NVIDIA designed a wicked vapor chamber a la ATI Radeon 2900XT, threw out the exposed gigantic heat pipes, and managed to tweak the design to draw less power, all while delivering around 20% more performance.

I was fortunate enough to get to test out a MAINGEAR SHIFT with both 2-way GTX 480s and 2-way GTX 580s and can show you some numbers. So let's get started.

By now you may have heard the numbers, and recently the rumored specs have solidified into the truth. Yes, it has 512 shaders. Yes it is clocked at 772MHz and delivers 192.4GB/s of bandwidth.

Here's what we shoved into a SHIFT for this test:

Core i7 970 @ 4.135GHz
6GB of DDR3 2000MHz memory
Rampage III Formula
128GB Crucial RealSSD C300
And all the rest.

In comparison to the Nvidia 480, you see anywhere from a 10-20% increase in performance. There is plenty of reason to get excited about this though. Dual GTX 580's consumed about 40 watts less than dual GTX 480's. And you would not believe how much quieter they are. It is striking. Unfortunately I didn't bring a SPL meter with me, but NVIDIA reports it's about 50% quieter. I do not doubt for a second that is an accurate assessment. I was floored.

Can you see Billy Mays selling this thing? "THE NEW NVIDIA GTX 580 IS FASTER. IT'S QUIETER. IT USES LESS POWER! AND BEST OF ALL, IT'S THE SAME PRICE. THAT'S RIGHT FOLKS, THE ALL NEW GTX 580 IS NOT ONLY THE WORLD'S FASTEST SINGLE GPU ON THE PLANET, IT'S THE SAME PRICE AS THE GTX 480! BUT WAIT, THERE'S MORE. BUY THE GEFORCE GTX 580 AND GET FREE(!) SUPPORT FOR CUDA. FOR 3D VISION. FOR PHYSX! ALL OF THESE COME BUNDLED IN THE NEW NVIDIA GTX 580 GRAPHICS CARD!"

OK, so maybe it's only me. But either way, this bad boy is replacing the GTX 480 in my book, ASAP. EVGA also offers a Superclocked version for those of you who still want "MOAR POWAH!"

Simple and Easy Microwave Repair Tips

!±8± Simple and Easy Microwave Repair Tips

A microwave oven is a common household appliance. Sometimes it simply refuses to work and will leave us confused and wondering what went wrong. Here are some common problems that can occur with the oven and a few microwave repair tips to resolve them.

Sometimes your microwave will not switch on. The first thing to check is the plug. Ensure that it is plugged in properly and the door is correctly closed and aligned. If there is a blown fuse you can replace that or reset a tripped circuit breaker. Turn the switch on. If it does not work then there might be other issues or you may have to contact a professional.

If the microwave keeps blowing fuses or tripping a breaker check its door switch. Find the door switches and take off the leads. Probe the terminus using a volt ohm meter. When the door is open the reading has to be infinity and when closed it should be zero. If these readings are not correct, replace the switch and check again.

Sometimes the diode or the capacitor may be bad. Test the capacitor using the voltmeter. The reading should gradually increase to infinity. Test again by reversing the probes. The reading should be the same. If it is not, it is damaged. Similarly, test the diode as well. The two readings have to be opposite. If they are not you need to replace them. But if you are not able to identify the problem, you need to call a professional.

The carousel may not turn sometimes. It is driven by a small motor and is not related to the heating function. You have to check the plastic drive coupling on which the tray is found and also the ring and roll assembly. You have to open the microwave cabinet to fix it.

If you feel that the microwave cooks unevenly or relatively slowly, examine the voltage at the power supply. If it's less than 115 the trouble is with the electrical service. A bad motor can also cause the problem. To check this, remove the grill at the bottom and check using the voltmeter after setting it to RX1 and removing a lead from the terminals of the motor. You will have to replace the motor if the reading is infinity. Even the wave guide and the magnetron can cause problems.

The touchpad may work erratically or not work at all. If by any chance your touch pad has become wet, let it dry properly. Do not spray any cleaning liquid near it. If you have insects in your kitchen, check for infestation by insects. They are most likely to appear under clear surfaces and in between the circuit boards to feel the warmth. Cover the vents by placing a window mesh to keep away insects.

If you still are unable to fix your microwave or find some other persisting problems you should contact a microwave repair professional for assistance.
