Re: Cheap, readily available sound meter

Another inexpensive SLM is the Polarich Smart Sensor AR-834 datalogging (ANSI 1.4 Type 2) meter for about $100 (Canadian - from NCIX) that measures from 30 - 130 dB. When rebranded by Extech it can cost several times as much. Without memory but also 30-130 dB, the AR-824 is $10 less. On Ebay by ano...

Re: How to estimate overall sound level

Good reading, thanks for the links. It sounds like my limitation at measuring things will relate to my access (or lack thereof) to an anechoic chamber. Wonder if my alma mater has one available...

Re: USB3 ports on front of case

Scythe Kama Cabinet Pro is USB 2 for about $15 and has a nifty hidden storage feature.

Bitfenix USB 3.0 Front Panel - 70721 is about $25 and has four USB 3 ports.

As soon as I get a MB that has USB 3 I'll probably get a USB3 front panel.

anybody know of a cheaper front panel for USB 2 or USB 3?

Re: Overclocking Athlon X4 630 on Biostar TA790GXBE

Yeah, I don't think this will work with the X4 630, as it's multiplier locked so the only way to overclock it is to increase the FSB. If you are multiplier locked the FID won't change but you can change the DID and voltage. It can be useful for over or undervolting but it won't help you in most ove...

You can do the old fashion BIOS overclocking but if you do you lose out on Cool n Quiet. You literally have a hotter system, and you'll likely be dealing with more noise for little or no gain vs other methods. Myself I left the BIOS options at normal/reliable settings (no overclock during boot) then...

The CPU and GPU are sharing that ram so if a program were using both close to equally contention could slow both down more than 20% each. Any time waiting on data means zero work.
