Massive 10 Motherboard i845E/G Roundup

Massive 10 Motherboard i845E/G Roundup - PCSTATS
Abstract: Traditionally, Intel chipsets have always been the fastest and most stable for Intel processors; just consider the venerable i440BX, i815E or even the i850E.

The i845E, i845G and the new ICH4

In the quickest terms the i845E chipset is basically the i845D validated to run at 133 MHz (533 MHz). Other then that, there are no architectural differences between the two Memory Controller Hubs (MCH a.k.a. Northbridge). The i845E chipset still only officially supports PC1600/2100 DDR memory.

Even though many i845E boards have three DIMM slots, the i845E can only take advantage of a maximum of four banks of memory. Basically, if the motherboard has three DIMM slots but you're using two double sided sticks of memory, the the third free slot will not work - even if you install memory into it. This limitation is very similar to the one found on the original i815 line of chipsets.

The i845E chipset is also limited in support of graphics cards to 4x AGP videocards which run on 1.5V. To try and ensure there are no mix ups with 3.3V videocards, all Intel i845E chipset based motherboards have the 1.5V AGP lock.

The i845G Chipset:

The i845G is very similar to the i845E except that it has an integrated video controller (Intel Extreme Graphics). Officially, other then the on board video controller, the i845G and i845E are technically identical.

Unofficially, the i845G has a memory divider that allows for PC2700 (DDR333) use, and as you'll see in the upcoming benchmarks this extra bandwidth can come in very handy. At stock speeds, i845G based motherboards are often faster then their i845E counterparts.

The i845G chipset was not able to escape the four bank memory limitation that all the other i845 chipsets have unfortunately.

Even though Intel Extreme Graphics controller is based on a shared memory architecture (the controller takes either 1MB or 8MB of system memory), it's still a big step in the right direction for on board video, and actually quite useful.

The Intel Extreme Graphics core is no where close in terms of 3D performance to a GeForce4 Ti4600, but it's a lot better then all the other on board solutions out there right now.

3D performance is about the same as a GeForce2 MX200, and while that may sound bad, in terms of integrated graphics that is pretty damn good. Intel knows though, if you're going to be using the integrated graphics core you probably won't be gaming, and the real strength of the Intel Extreme Graphics core lies in its 2D image quality. Text is very well defined and readable, pictures and other still imagery are quite vibrant even at resolutions of 1280x1024!

For those who want to game with their i845G based motherboard, never fear. All i845G based boards should have support for a 4x 1.5V AGP slot, though but not all boards will have it physically installed.

The new ICH4 Southbridge:

GeForce2 GTS, Voodoo5 5500 and Intel ICH2, what do these three things have in common? They're all about two years old and when you think about it, in an industry where three and six month product cycles are a long time, it's amazing that the ICH2 has been with us for so long. Finally with the release of the i845E/i845G comes a new I/O hub, the ICH4.

Since Intel never endorsed the Ultra/133 IDE standard rather focusing their energies on Serial ATA, the ICH4 can only handle HDD's up to Ultra/100 (Maxtor Ultra/133 drives will default to Ultra 100 when used with the ICH4).

Also integrated into the ICH4 southbridge is an 5.1 AC'97 codec and a software 10/100 LAN controller. The biggest upgrade the ICH4 has over the ICH2 is onboard USB 2.0. With a total of 6 USB 2.0 ports you'd be pretty hard pressed to use them all.
