One Tough Cookie: 10 Boards with Intel i875P Chipset: Part I

Abit IC7-G: Below Expectations, Continued

Abit IC7-G : Below Expectations, Continued

A look at the connections of the Abit IC7-G.

Four RAM slots for dual DDR400 on the Abit board.

Similar to the Asus P4C800 : lateral IDE connections.

So Abit has parted from its longstanding supplier, Highpoint. Now, a few details on the test run : the manufacturer waited a while to send us a BIOS version that marginally increased performance. We also have the suspicion that Abit is struggling with the RAM interface - reasons for this could be BIOS or the board layout. From the factory, the board boots with a RAM voltage of 2.6 volts - 2.5 volts are standard. Otherwise, the boot process may abort on occasion with certain RAM modules at 2.5 volts. In addition, user-defined inputs for RAM are not accepted or are sometimes ignored : when booting, the board suddenly, automatically decreases the timings. Thus, Abit achieves the lowest performance of the entire test field - the manufacturer should do a little more fine-tuning on BIOS, at the very least. The results are shown in the table below.

Corsair XMS3200V1.1 CL 2.0-3-3-6 (384.6)
Kingston KHX3500 CL 2.0-3-3-6 (384.9)
OCZ PC3200 CL 2.0-3-3-6 (380.4)
GeIL CL2-6-3-3 Ultra CL 2.0-3-3-6 (382.5)
Kingmax MPXB62D-68KX3 CL 2.5-3-3-8 (389.1)
takeMS mMS64D32000U-5 CL 2.0-3-3-6 (383.7)
Infineon HYS64D32300GU-5-B CL 3.0-3-3-8 (379.8)

The above table lists all the timings for the modules that we used, reliably read out using a diagnostic tool. One measurement for the speed is the frame rate achieved in Quake III Demo 1 (640 x 480 x 16).
