In usual Abit style, the SR7-8X features all of the CPU, Memory and AGP adjustments even the most hardcore tweaker could ask for. Firstly, Abit's SoftMenu III allows you to input any FSB frequency you like between 100 and 200MHz. Additionally, you are able to lock the PCI and AGP bus speeds at their default of 66MHz and 33MHz respectively. This allows you to increase the FSB without increasing the PCI or AGP bus, thus removing your PCI and AGP devices from being a bottleneck while overclocking. The CPU/DRAM/AGP/PCI ratio is also adjustable, from the settings 3:3:2:1, 3:4:2:1, 3:5:2:1, 3:6:2:1, 4:3:2:1, 4:4:2:1, 4:5:2:1, 4:6:2:1.
As far as voltage is concerned, the VCore and DRAM voltages are adjustable, with available VCore adjustments of +5%, +10% and +15%. DRAM voltage can be adjusted from 2.6v, 2.7v and 2.8v. Using a core voltage setting of +15% and default DRAM voltages, I was able to overclock my 2.4GHz Pentium 4 (18x133) up to 2.7GHz (18x150). This is an 'OK' overclock, however, this particular processor has been clocked quite a bit higher on various i845E boards we've tested and we can't help but be slightly disappointed here.
Overall, we were quite impressed with the Abit SR7-8X motherboard. However, it was not without its faults. Although it offers high performance that is superior to that of the i845E chipset at stock speeds, its lackluster overclocking results may be a letdown for some users. As far as features are concerned, the SR7-8X does not disappoint, however, the addition of onboard RAID and Firewire would have been nice.
The bottom line is, if you are looking for a high performing motherboard with a decent amount of features for your Pentium 4 processor and do not intend on doing any extreme overclocking or utilizing RAID, I do not have any trouble recommending the Abit SR7-8X. At a price of around US$100, it will also be very appealing to those on a budget.
