Abit AB9-Pro: Overclocking
FSB Overclocking Results
Our E6300 posted very good results when compared to our earlier overclocking test results that resulted in a maximum FSB speed of 366. However, the 7x436FSB level is the lowest of our test group today and does not match up to the promise of this board's performance. We also have an issue with our CPU requiring 1.4375V on this board to reach a stable 3.05GHz. We normally only require 1.40V in order to reach this level and noticed the board would not boot without an increase to 1.4375V although it was rock stable at this setting. Vdroop averaged around .02V to .03V during overclocking and heavy system loads. Our memory is usually very stable up to DDR2-900 at 4-3-3-10 settings but required slightly looser timings on this board. Although the overclocking results are not as high as our other boards, the ability to now run up to 436FSB in a stable manner is fine for the majority of people who want to overclock.
Memory Stress Testing
Memory stress tests look at the ability of the Abit AB9-Pro to operate at the official DDR2-800 memory frequency at the best performing memory timings our GEIL PC2-6400 can achieve on this board.
The Abit AB9-Pro was very stable with 2 DDR2 modules in Dual-Channel mode at the settings of 3-3-3-9 at 2.2V with the 1.4 and above BIOS. By increasing the voltage to 2.25V we could run at 3-3-3-6 timings although there were not any real performance improvements unless we utilized MemSet to change other latency settings.
We had to change our timings to 3-4-3-10 from 3-3-3-9 when installing two additional modules. We were able to keep our voltage set to 2.20V at this setting. We were able to maintain these settings up to a 7x405FSB, DDR2-810, setting with 2.30V. Our maximum overclock with four DIMMs installed was 7x418FSB, DDR2-836 4-4-3-12, with the memory set at 2.30V. Once again, we had to use BIOS 1.4 or higher in order for these settings to work.
In fact, on the first two BIOS releases this particular memory would not even boot when installed in this board. The memory itself is designed to run at 2.0V or higher depending upon the latencies selected. GEIL actually rates this memory at 2.4V for 3-4-3-8 operation at DDR2-800 although we have not required voltages above 2.2V at this setting.

I think that was a temporary glitch where the article went live before the last page's text was updated. Shame on you for skipping straight to the end.... ;)BadThad - Sunday, October 22, 2006 - link
Is the v1.02G Asus P5B-E using all solid capacitors? I read a press release stating that Asus was releasing the "P4B-E Plus" version with all solid caps. Rumor says the "Plus" version will not be sold in the USA.....arrgggggg. Tell me that's not true. I want the solid caps for long-term reliability. I'm wondering if our "Plus" is actually the v1.02G?
