Overclocking

To push the PC4000 to it's limits, the modules were installed in an ABIT IC7-MAX3 with a Pentium 4 2.4C. My main concern during the testing was how well our processor would hold up at these insane speeds. However, setting the memory to 250 MHz with timings of 3-4-4-8 and a voltage of 2.8 gave me quite a surprise when the computer booted into Windows at a very comfortable 3.0 GHz.

After some stress testing and insuring that the system was stable, I slowly increased the memory speed MHz by MHz until I reached a slightly unstable 256 MHz. The highest stable overclock I was able to achieve was 255 MHz at 2.8 volts which brought the 2.4C from 2.4 GHz to 3.06 GHz. Any further increase in voltage had absolutely no affect on stability.

Test System

As stated earlier, the memory was tested in an ABIT IC7-MAX3, which utilizes Intel's 875P chipset, and a Pentium 4 2.4c. The CPU/RAM was at a 1:1 ratio throughout testing. The Corsair TWINX512-4000 was tested along with two sticks of Transcend 256 MB PC4000 (a total of 512 MB). All memory was tested in dual channel mode with timings of 3-4-4-8.

Test Rig:

Pentium 4 2.4c
ABIT IC7-MAX3
PowerColor Radeon 9800 XT (Catalyst 4.2)
200 GB Maxtor DiamondMax Plus 9
LiteOn 16X DVD-ROM
Soyo Raptor 400W Power Supply
Windows XP Professional (latest updates)

The following memory was used during testing:

2x 256 MB Corsair TWINX PC4000 @ 400MHz (3-4-4-8) / CPU @ 2.4 GHz
2x 256 MB Corsair TWINX PC4000 @ 500MHz (3-4-4-8) / CPU @ 3.0 GHz
2x 256 MB Transcend PC4000 @ 400MHz (3-4-4-8) / CPU @ 2.4 GHz
2x 256 MB Transcend PC4000 @ 500MHz (3-4-4-8) / CPU @ 3.0 GHz

The question out there now is: Which RAM are you currently running in your personal game machine???

neither of us have time to game... :(

But as of right now, if he was gaming, he would be using this memory :)

whatever cheapass Micron memory comes with a Dell

not that Micron is bad stuff, but its certainly no speed demon

Right now I have 2x 512 MB of Corsair's PC3500. The PC4000 will be going in my next rig :-P
