Re: A question for all electronics-literate out there (12V-to-PWM-adapter)

AFAIK the boards with the "fake" PWM fan headers do have a fully functional 4-pin header for the CPU (just like previous boards, though then only the CPU had a 4-pin and all others were proper 3-pin headers). The problem is none of the other 4-pin headers seem to control speeds properly w...

Re: A question for all electronics-literate out there (12V-to-PWM-adapter)

It would be wise to check the voltage swing of the fan header with the chosen resistors though; it may not behave as expected if it doesn't see a load similar to that of a typical fan. If the output needs to be loaded, then lower resistance (and higher wattage) resistors may be needed to simulate t...

Re: A question for all electronics-literate out there (12V-to-PWM-adapter)

Sounds to me like he's trying to do the reverse -- i.e., he has a motherboard fan output with voltage control, and wants to convert it to a PWM output. (My apologies to the OP if I've got it backwards.) You are correct :-). The reasons being: a) PWM-fans are not designed for voltage control, and ma...

A question for all electronics-literate out there (12V-to-PWM-adapter)

I have one of those motherboard with "fake" PWM system fan outputs, ie. they are regular voltage controlled outputs with "PWM fan support". I thought I'd remedy this in a relatively clutterfree manner, so I bought a couple of these: 0-10V -> PWM converter I guess I have to divide...

Because such a card should have no problem displaying that resolution, provided that an DP, HDMI or dual-link DVI cable can be/is used.

Re: Korean S-IPS 2560x1440 Monitor for Gaming

Seeing how they "may have dead pixels", I would never buy it. Especially since these monitors also are sold with a pixel guarantee for a premium. Ie, these didn't make it.... :-)

And I could never stand a monitor with even one dead pixel.

Alright. Beside from the fact that a SSD will make almost *any* system this side of 2005 feel much more responsive, there aren't so many benefits game wise aside from perhaps faster loading times. In the scenario when the system is low on RAM and the system starts swapping, you're still better off b...

Re: PC immediately resumes sleep mode after being woken up

Hows temperatures and such? You could try running something like Prime95 and stress test the machine, together with Open Hardware Monitor or HWMonitor, to monitor heat.

Also, maybe I missed it, but do you have any peripherals connected, like USB and such? Or any discrete cards in the machine?

The power supplies seems to be either 110-127V or 220-240V. You could always buy a voltage converter, just make sure it handles the wattage of you supply (depends on which version of the Xbox you got).

Re: Virtualization and Ivy Bridge

I think most of their processors do nowadays, except the budget models.

Easiest way to find out, though, is to just google the model and you'll get Intel's own specs somewhere at the top. They're informative and easy to read.

Re: Upgrading for HDMI audio...

Unless you're gaming on the HTPC, I'd go with option 2. You won't need anything powerful for accelerated video, and it will probably draw quite a lot less power, thus generate less heat and noise.

Or, if there's a SPDIF_Header on the motherboard, use that.

Re: Phenom II X6 running hot?

Probably because it's in BIOS and, as said earlier, the power-saving features aren't in action.

Using eg. CPU-Z in Windows, you will probably see it go between 1.125-1.4V when idle and under load respectively.

Re: Phenom II X6 running hot?

In BIOS? And which processor model is it? The voltage sounds too much, but if the frequency comes up as higher in BIOS than the rated speed for your model, it is obviously Turbo Core'ing, and I don't know if that also raises voltage to accommodate the higher frequency. 57C is still toasty, but again...
