Asus P5WD2 Premium: Overclocking
FSB Overclocking Results
| Front Side Bus Overclocking Testbed | |
| Processor: | Pentium 4 Prescott LGA 775 560 ES (2.8GHz-3.6GHz) |
| CPU Voltage: | 1.425V (1.3875V default) |
| Cooling: | Thermaltake Jungle 502 |
| Power Supply: | OCZ Power Stream 600 |
| Maximum CPU OverClock: | 227x18 (4086MHz) +14% |
| Maximum FSB OC: | 291FSB x 14 (4074MHz) +46% |
Asus has fully implemented Speedstep in their recent BIOS updates for Intel Socket 775 motherboards, so the OC results are a lot more than academic. Speedstep means that the stock multiplier and a 14X multiplier will be available on all Prescott CPUs, opening new options for overclocking regular Intel Prescott chips.
With a stock multiplier, the P5WD2 reached an overclock of 227x18 or 4086MHz. This matches the highest frequency ever reached with this 3.6GHz Prescott, which was with an Asus 915 chipset board. The 46% FSB overclock achieved at the 14X multiplier is the highest OC that we have seen with a SATA drive on a Socket T board. The previous Socket T record on this CPU was 279FSB.
While we were able to reach these OC levels above 4GHz with the Thermaltake HSF, the long-term stability with air cooling at these speeds is very suspect. After running a few tests, the system began throttling - alternating between stock speed and reduced speed due to overheating. There is no doubt that the CPU can do these speeds, but you will have to provide better cooling if you plan to run much above 3.8GHz. Others have demonstrated even higher Prescott overclocks and stable operation with water cooling and phase-change cooling.

Wow, 3% increase. That falls within a margin of error.HardwareD00d - Wednesday, May 11, 2005 - link
This article did an excellent job of showing why DDR2 is total crap. Until they can tighten up the timings, DDR533==DDR667==DDR800 pretty much.quicksilverXP - Wednesday, May 11, 2005 - link
Hey,What bios was your board running at? I purchased two recently, and both of them don't have the DDR2-800 option. I noticed you have 7 ratios available while mine only has 5, and only up to DDR2-667. My Bios version is 0124 from the POST screen. Can you help me out?

"Heatsink" is one word. If you are describing a general "heat sink" (there is a distinction), then you are talking about something else.Furthermore, fans are in fact considered active cooling. Active cooling by definition is any cooling device that can be disabled/enabled at will. Heatsinks are passive; fans, peltiers, etc are not.

well, anyone know where I can find this?what is the msrp for these (dual core) boards, cause those $255/$245 prices on newegg/ZZF are hard to ignore...

"a fan doesn't actually cool anything, it just pushes air around"Try disabling the fans in your rig and A/C, take temp readings before and after and get back with us. Moving same temp to same temp isn't cooling. Moving cooler air (or water or other) to something that is hotter (chip, compressor, radiator, etc) most definitely actively cools it.

heat sink is two wordsfans are not active cooling. air conditioning is active cooling, turning the ceiling fan on in your room is not. a fan doesn't actually cool anything, it just pushes air around.
thanks!

My retail package also did not include the WiFi/Tuner and Remote. Still a great board though. :)jonny13 - Wednesday, May 11, 2005 - link
Why the hell is Doom3 listed under DirectX 9 gaming?Someone should tell Carmack that he was actually coding in DirectX 9 and not OpenGL like he thought...
Also, on the third graph of the General Benchmarks, you have the orange color as the Asus P5ND2-SLI instead of the Asus P5WD2 like every other chart. If you are going to use colors for the graphs, at least be consistant.

#6Hypertransport is an open standard. Neither AMD nor NV owns it.
#10
A64's also use Hypertransport to connect the processor to the northbridge.
