Re: News for 2011-02-10

Surely this is bait-and-switch fraud! You can't advertise a product as a certain spec and then silently make it worse and expect to get away with it. Their numbers don't add up either. If the maximum program/erase cycles decreased from 8000 to 5000 that is nearly a 40% reduction, but the amount of s...

Re: 220V alternative to Kill-a-Watt Power Energy Meter

I don't know what is inside, I bought about ten for £1.80 each from Wilkinsons years back so never needed any more. The ones I have use fairly a standard power resistor and op-amp circuit, easy enough to interface.

Re: 220V alternative to Kill-a-Watt Power Energy Meter

PM230 should be avoided, apparently. A normal meter measures below 1W. Max 3680W (16A). ...batteries? Only for moments when the meter is not plugged in. For clock, settings (like kWh price), results. No, they need them all the time to work. Without the batteries you get nothing at all on the displa...

Why is it that the UK versions need batteries? The Japanese and US versions are powered from the mains which seems obvious. It must have something to do with safety.

Re: News for 2011-01-21

You are both looking at extremes. Ces, in the case of a passively cooled CPU it is obviously going to run an awful lot hotter. What we are talking about is the difference between a 5V fan and a 7V fan at most. The 6xx0 cards run very cool at idle anyway so I bet the difference is no more than a 5C b...

Re: News for 2011-01-21

They are controlling the fan speed based on temperature. It's just one BIOS makes a different decision on how cool or hot to allow the card to get than the other. Just as you may decide to run a hard drive without a front case fan to cool it and I may decide to put that 92mm or 120mm front case fan...

Re: News for 2011-01-21

It still seems pointless to me. Why not just control fan speed based on temperature, that way it can be silent at idle in most systems but run a bit quicker in really hot ones. I think it is more of a marketing tactic. By having a little switch that changes between quiet and performance people think...

I'm not sure I see the benefit of dual BIOS cards. When not gaming performance of even the lowest end cards is more an adequate for desktop, 1080p video and even CAD and most 3DS work. Therefore there is no advantage to a powerful card like the 6850 running at anything other than the lowest possible...

It allows you to do Hybrid Crossfire which is using the on-board and the discreet GPU in a Crossfire configuration. The performance boost from using the on-board is usually negligible so it is more for convenience than performance. Unfortunately the graphics card does not shut down completely so sti...

Re: Zalman CPU & VGA Power Consumption Meter

You could get a similarly accurate reading just by measuring at the wall when the computer is idle and under load with an ordinary power meter. Since you know the minimum power consumption of both the CPU and the GPU thanks to sites like SPCR you can then estimate the load consumption pretty well.

I tried the Apple keyboard out for a couple of hours and was not very impressed. I think the problem is mainly lack of travel on the keys. The spring in most keyboards pushes your fingers back up...
