Memory Stress Testing

Memory Tests - ASUS P5B-E 1.02G

We now take a look at the 1.02G revision motherboard to see if additional memory voltage can improve our timings on the GEIL PC2-6400 modules.

ASUS P5B-E 1.02G
Stable DDR2-800 Timings - 2 DIMMs
(2/4 slots populated - 1 Dual-Channel Bank)
Clock Speed: 800MHz
CAS Latency: 3
RAS to CAS Delay: 3
RAS Precharge: 3
RAS Cycle Time: 9
Voltage: 2.20V

We were able to set our timings to 3-3-3-9 by increasing the memory voltage to 2.20V with our GEIL memory. This also held true for several other DDR2-800 modules that required at least 2.2V for improved memory settings. Although the performance differences are negligible, the additional memory voltage will assist in overclocking and allowing most memory modules to run at tighter timings at like memory speeds.

ASUS P5BE 1.02G
Stable DDR2-800 Timings - 4 DIMMs
(4/4 slots populated - 1 Dual-Channel Bank)
Clock Speed: 800MHz
CAS Latency: 3
RAS to CAS Delay: 4
RAS Precharge: 3
RAS Cycle Time: 10
Voltage: 2.20V

The 1.02G board allowed us to run four DIMMs at 3-4-3-10 with only 2.2V which matched the Abit board. However, we were able to overclock the board to a very impressive 7x483FSB, DDR2-966 4-4-4-15, with four DIMMs installed; however, this required us to increase our memory voltage to 2.35V. Our maximum overclock at 3-4-3-10 with four DIMMs was 7x410FSB (DDR2-820) at 2.30V which means we were already near our maximum limit at these timings. We were able to reach 7x440FSB (DDR2-880) with our memory set to 4-4-3-10 at 2.3V.

    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.... ;)

    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?
