Introduction
Prior to use the system for 3DMark2001SE benchmarking session there are lots of preparation involved before you can get some real satisfying results. First you will need to select the hardware you are going to use for the setup and choices must be good so they can yield the highest performance. For motherboard, i have selected ASUS P4T533-C based on i850E board since the RDRAM motherboard will give the best 3DMark score. The choice of graphics card is important too and i have selected using MSI GeForce4 Ti4600 for benchmarking. I have modified the motherboard and graphics card to increase the voltages for better overclockability and also employ LN2 cooling to the CPU and GPU to push their frequencies much higher than default.

VRIMM Mod
Vcore-modification is quite easy to accomplish. Beside the Socket 478-base we can find the R3217 resistor which is replaced with 56kohm adjustable resistor. When the resistors value is decreased the processors operating voltage is increased.
Luckily also RDRAM operating voltage is easily increased with help of little modification. Near the ATX-connector we can find the R2300 resistor which is replaced with 1kohm adjustable resistor when the value is decreased the memory voltage increased.
The main purpose of using a Turbo PLL is to overcome the FSB limitation of the motherboard especially that i850E boards usually has a maximum of 156Mhz FSB.
For the TurboPLL connection you must get external clock circuit and 14,3MHz crystal. This is best done by sawing up those apart from old broken motherboard. It is worthwhile to get such clock circuit which you can get datasheets from the internet. From the external clock circuit you must know the following connectors: 3,3V operating voltage, GND and 14,3MHz output. When above-mentioned factors have been sorted out, you must remove the 14,3MHz reference crystal from the Asus P4T533-C motherboard. It is worthwhile to connect base so you can easily change different kind of crystals. After this you have to disconnect resistors R143 and R144 near the clock circuit. The outer clock circuit feeds 14,3MHz reference frequency to the motherboard. Wires (in the picture red and yellow) are connecter into the disconnected resistors outer pins (when you look from the clock circuit).
Blue wires feed the operating voltage +3,3V and GND to the external clock circuit. Motherboards 14,3MHz crystal was replaced by 16,93MHz crystal. With fast calculations we get the motherboards smallest possible channel frequency of 118,39MHz and the largest possible channel frequency of 177,58MHz.
(16,93MHz / 14,3MHz) * 100MHz = 118,39MHz
With different kind of crystals you get different kind of channel speeds of course. For example 20MHz crystal the 150MHz channel speed is 209MHz.
Modifying MSI GeForce4 Ti4600
First I did some testing using standard configuration: A P4 2.4Ghz, EPoX EP-4T2A3 motherboard and Win 98 OS. I tested all possible settings with RivaTuner software. After inital tests, it was time to start overclocking with Pentium 4 2.4Ghz, Windows XP, ASUS P4T533-C and Microstar GF4 Ti4600 motherboard. After testing a few versions of drivers, i have discovered that Detonator 29.42 works the best. I have tested graphics card maximum core/mem clock frequencies with standard cooling and voltage which is found to be 325/730MHz.

Final
I have attached some RAM sinks to the memory and apply the VMem mod ( by adding a 1Kohm resistor to increase the voltage from 2.80V to 2.95V. After applying the VMem mod, i am able to overclock the memory from 735Mhz to 775-777MHz which is an improvement of 40Mhz. Although i have changed the default cooler on the card to a better heatsink but it didn't really help much so i have to resort to LN2 cooling. I have applied the VGPU mod by adding a 5KOhm resistor to increase the voltage from 1.66V to 1.93V.

During the initial testing, the core frequency limitation is at 378Mhz but after some time, the GPU is completely frozen on both sides and i could even complete the 3DMark tests at 400Mhz core frequency. Not only i have applied LN2 cooling to the graphics card, i have done the same thing to the motherboard too. From the previous testing, I knew that Pentium 4 at 3860MHz (24x160.85MHz) was solid as a rock. For the first test, i have set the core/mem frequency to 395/775MHz and got the initial result of 16636 3dmarks. I have put in more Liquid Nitrogen and continue to run 3DMark tests again and got a score of 17100 3dmarks.

For the final showdown for the highest 3DMark score, i have applied LN2 cooling to the graphics memory even and increased the VMem to 3V but there was no improvement from doing so. I also raised the GPU voltage to 1.98V and the 3DMark tests went through at 409MHz core frequency. At the same time I have further increase the CPU frequency to 3917MHz (24x163.20MHz) and i have set a record of 17230 3dmarks! You can compare your results with mine [url="http://service.madonion.com/compare?2k1=3990219"]here[/url]. It will be interesting to benchmark with a RADEON 9700 too since it is about 20% faster than GeForce4 Ti4600 so a score of 20,000 3dmarks and above will be attainable.

vid kaart. proc. etc allemaal uit 2002 natuurlijk liggen die scores hoog, die 3dmark is voornamelijk gemaakt voor videokaarten die toen super waren enzo ik ben niet onder de indruk van die scores en iedereen ik haal met 3dmakr hoog en UT2003 is bagger... jah duh ut2003 is gebasseerd op de videokaarten en computers van NU 3dmark van 1/2 jaar geleden.
