Introduction :

My VIA adventure began with the Aopen AX63 Pro which is based on the original VIA Apollo Pro 133 chipset! This board replaced my last BX board since, the Abit BH6. I chose this Aopen board because I was curious to find out if the (then still) infamous VIA was capable of breaking through Intel’s BX monopoly! And after a short wile, VIA showed the world that this had become a fact! Compared to Abit’s BH6, the AX63 Pro gave me great stability for my overclocked Celeron 300A @ 504 (remember that one?) but never the BH6′s BX performance; not even close!

Then along came Asus’ P3V4X motherboard based upon the new & improved VIA Apollo Pro 133A chipset, pulling in some quite decent reviews. But still not up to the good old BX for overall performance, but the gap had closed quite a bit compared to the AX63 Pro.

A few months later Asus served us with their FC-PGA version of the P3V4X, the CUV4X containing the slightly updated (improved??) VIA Apollo Pro 133Z chipset.

The Board :

Dipswitches on the mobo can also be used to set the FSB/PCI/Core Voltage. However, the factory default setting has all the jumpers turned ‘off’ which results in using Asus’ ‘Jumper Free’ BIOS menus which are much easier & faster to use, especially for the serious tweakers & overclockers among us! Or also for those who want to mess up there system, this is possible using incorrect or a little too optimistic settings in the ‘Jumper Free’ BIOS menus … :)

What about overclocking ?

Shortly after I got my CUV4X system up & running, I immidiately pushed my 700E beyond the 133Mhz FSB. This wasn’t possible with my P3V4X. However, I do think the problem here was the Abit Slotket III not the mobo. With my CUV4X I was able to overclock my 700E to speeds well above 1Ghz. Only one thing sucked here : my PC133 RAM! The poor thing is maxed out @ 142Mhz. With a small calculation, that gives me a CPU speed of 994Mhz @ 1.85V. Then I started to get really pissed, because I wanted to see the 1008Mhz appearing on my screen when my system boots up & this without having to lower the RAM speed (3/4)! Damnit!!

I can say my 700E runs stable @ 994Mhz. I did some benchmarking and I played Q3A & UT for a couple of hours without any BSODs or system failures. Then I lowered my RAM speed & tried to raise CPU speed further. Even 1050Mhz (150Mhz FSB) was possible without causing the system to hang during bootup, benching or gaming. This is really not bad at all!

Test system :

CPU : Intel PIII-980 (FSB:7x140Mhz)

Mainboard : Asus CUV4X 1006 bios

Chipset : VIA 694Z Chipset (4in1 4.25a driver)

Video : Creative Annihilator Pro Geforce DDR (deto 6.35)

Memory : 128MB PC133 (2-3-3)

Harddisk : IBM 20GB UDMA66 @ 7200RPM

OS : Win ME

Some benching & figures :

These Sisoft Sandra results show that this mobo is quite fast when it comes to pure CPU & memory power. Let’s see how it handles the Quake 3 Arena Timedemo 1 …

These benches were taken with the Geforce DDR not overclocked! We can notice one thing here: how higher the screen resolution goes, how more the difference in FPS (frames per second) between 16bit & 32bit becomes clear. Everything put together, these are not real bad benchmark results at all!

One last thing before we jump to the conclusion. I also did the default 3DMark2k bench on this CUV4X and it gave me this score :

(quite good actually!)

Conclusion :

As much as Tim likes his Abit SE6 board, I like my Asus CUV4X. This is the most stable board I’ve ever seen in my whole life so far! It guarantees great & easy overclocking and overall performance, although 3D performance was very low on my CUV4X (possible due to a driver problem??). It has nearly all features that most people expect from a mobo these days.

Pros :

- Great stability

- Easy overclocking

- Additonal USB card (+2 USB)

Cons :

- Slow 3D performance

- 4in1 Driver

Thx 2 our friends over @ PC Critix 4 the mobo pics …
