Intel D850GB P4 Motherboard Review

Intel D850GB P4 Motherboard Review - PCSTATS
Abstract: Intel are known more for their line of incredibly successful processors than their motherboards, but if the D850GB is any indication, they can definitely hold their own...

Features: Processor Throttling

Turning our attention to the processor socket it is good to see that for the most part there are no crowding issues. Occasionally, really large capacitors find their way to the processor like a bunch of groupies around an aging rockstar. In each case they limit access to the center of our attention, and in the case of our good old processor, can make installing the chip or heatsink rather awkward.

As far as we're concerned with the D850GB, this small grouping of capacitors is out of the way. They do make it a bit of a tight squeeze to plug in the 4-pin 12V VRM power lead, but not overtly so.

The processor socket is in fairly open territory with no large processors crowding it in, or blocking off the flow of air from the heatsink.

While the fit is a tight one for the 4-pin power connector, we had no real difficulties.

CPU Throttling

Unlike its AMD counterparts, a Pentium 4 in trouble is adept enough to realize something is wrong and decrease speed or shut down. These wondrous actions come thanks to an internal diode which thermally monitors your expensive processor in the event of something catastrophic like fan failure. If the processor exceeds its operating temperatures it will shut down until the temperature has returned to a reasonable level.

After all the last thing you would want to do is fry a 1.7 GHz processor in 4 seconds....

Tehama Heatsink

On the thermal side of things we see that the Tehama chipset is covered by a new type of passive heatsink. Unlike the BGA chipset coolers of old, the i850 heatsink is rather specialized. Namely, the heatsink is attached to the FC-BGA chipset by means of two small spring catches that hook into two little soldered in loops on the board. Where as the BGA coolers we are most familiar with attach directly to the PCB by means of small plastic pegs, or if it is a real quick job, by adhesive 'thermal' tape.

The Tehama chipset heatsink clips onto the motherboard with small hooks and has some thermal interface material on the base.

It is easy to see that a lot more care has gone into these specialized heatsinks then the older green BGA heatsinks that were all too commonly used. The Tehama heatsink even goes so far as to use thermal interface material and a small ring of spongy material minimize the possibility of damaging the exposed silicon core of the i850 chipset.
