AOpen AX4R Plus is a new Dual-DDR (Granite Bay/Intel i7205) P4 motherboard with VCore down to 1.1V and FSB all the way down to 66mhz (266QDR).

Asus A7V133 supports low voltages, all the way to 1.1V. (I successfully ran 1700XP at 1GHz @ 1.15V for a while, as described in my article). Too bad Asus completely screwed everyone over with their new products. I contacted them about P4B533's lack of undervolting, and they passed my request to thei...

Actually, at least one person (Technonut on Anandtech) got lower voltages working by using a motherboard that supports it. Also, if my calculations are correct, the P4M uses ~15% less power than a desktop P4 when both are at the same MHz and voltage . When you take the 12X multiplier into account, y...

Very nice Mike. I wonder if these results are applicable with a decoupled fan in a hood (like Ausone and my system). Probably so, because I tested both configurations and my temperatures were very similar. Have you considered using BURNK7 (for Athlon) or BURNP6 (for Pentium4) instead of Prime95? The...

Using a refurb Sony G500 (21" flat .24mm) CRT for close to two years. Refurb Sonys are luck of the draw, but mine is a winner--1600x1200 vibrant and clean at 85hz (max 98hz at that rez).

Mike, I don't suggest that people should sacrifice quietness for stability. However, if you don't intend to use your CPU 100%, then why not clock it down? When you overclock a 1.6A Northwood to 2ghz, the implication is that you actually need the extra speed, which means that at some point you expect...

This is certainly bad, but an even worse problem is that the person who reported it didn't "stress test" his system, as I bet many other quiet enthusiasts don't. If it cannot survive 100% CPU usage for long, that's a hardware issue, not software! Not to mention, thermal throttling kicks in around 80...

No offense, but I'm not sure if it's literally "totally silent", given that you are using a Panaflo that tends to emit motor-friction noise at 5v and that a fan directly mounted on heatsink could cause slight vibration of the heatsink. The fan isn't quite directly "on" the heatsink, I rolled some t...

"Do you have any other option with your case?" Yes, I think putting the fan in its "normal" place atop the PAL8942 may work better (with a duct) for these reasons: 1) The fan is deeper inside the case--so it generates less noise. 2) It is positioned right next to the heat source (CPU), so it should...

I'll buy better fans once my pocketbook recovers from all this :) Question about the duct: since the fan sucks air, the duct has lower pressure than outside air. Won't this cause the soft Ziploc ma...

If Zalman's reviews don't justify the $47 cost, I will probably make a Panaflo cooler and devise some reversible way to attach it. I could try constructing another fanless cooler, but I am afraid it will spoil my overclock. While the GPU may be cooled sufficiently by a heatsink, the rest of the card...
