We first tested the Prometeia cooler with the now late Asus P4G8X Deluxe. This board has some very good overclocking options:
- Flexible CPU Core Voltage Adjustments in 0.025V increments over defaults
- SFS (Stepless Frequency Selection) from 100MHz up to 400MHz at 1MHz increments
- Fixed AGP/PCI frequencies
- ASUS propritary C.P.R.(CPU Parameter Recall)
All these features were thoroughly tested, and worked flawlessly -- at least for a while. We especially appreciated the ASUS propritary C.P.R. that automatically resets the BIOS settings if you have been too eager in your quest for speed.
The temperature on the evaporator at idle at 3.06GHz
What we ended up with on the Asus board was 3820MHz using a 166MHz bus speed and 1.9Vcore. Many runs of SiSoft Sandra Burn-in and PCMark2002 were performed, but like we said on the previous page, the motherboard died. Nevertheless, 3.8GHz are impressive numbers, and the benchmarks were equally impressive. The Asus BIOS and Motherboard Monitor reported -11C at idle and 0C at full load.
Overclocking the MSI NEO-LSR Canterwood
If the Asus P4G8X Deluxe showed us some impressive numbers, the MSI NEO-LSR Canterwood board impressed us even more. After flashing the BIOS using the MSI Live Monitor, we ended up at a whopping 173MHz frontside bus(FSB) and 1.95Vcore, making the 4GHz mark close to touch. Alas, 3.98GHz was the closes we could get 100% stable during our extensive stresstesting. We did reach 176MHz FSB, or 4048MHz, but that also gave us an occasional hangup and even a nice and shining Blue Screen Of Death.
3DMark03 score at 3.98GHz. Note that we are using a lowly GF 440MX, which explains the low score.

We are unable to provide any temperatures for the MSI 3.98GHz overclock because the MSI montherboard simply doesn't understand temperatures this low (at least not in this BIOS revision). Hopefully MSI will fix this in their next revision.
