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.
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.
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.

In all the features tables for the motherboards in this article the PCI slots are listed as being PCI v2.3. However, looking at the pictures for the boards, the slots have PCI v2.2 keying. I think the entry in the features tables is wrong. (Is it?)Patsoe - Saturday, October 28, 2006 - link
Seeing all the trouble with the P965 - especially with the non-intel p-ata controller and with the ich8r - I'd be inclined to get a Core2-ready i945P board with ICH7R instead. Would that be a sane idea?BadThad - Tuesday, October 24, 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?Thanks

The 1.01G and 1.02G boards are exactly the same except for a PLL controller. Asus stills states the P5B-Plus will not be imported into the States but you never know.keithke - Monday, October 23, 2006 - link
I was interested to hear you used this Scythe Infinity Air Cooler as I was going to do the same. Were there any issues with the Northbridge heatsink sitting so close? Or did it just plop right in with no spacing issues?Thx

No issues with the Inifinity on all four corners. It is a close fit but it works fine with the enclosed fan.SniperWulf - Monday, October 23, 2006 - link
Hey guys,Did you have any strange anomolies with the X-fi on the DS3 while overclocked? When I was using that board with the F6 bios, I'd have to reboot like 3-4 times before windows would properly detect it. I eventually grew tired of it and bought a P5B-D so I haven't had a chance to try F7 with it.

I did not have any issues with the X-FI on the DS3 when it was overclocked. The F5 and F6 BIOS releases were not X-FI friendly where F4 was perfect. F7 is working for some and not others, I did not have an issue with it. F8 will fix it for good.schlumpfi106 - Monday, October 23, 2006 - link
Im a little bit disappointed that there are so few informations about the cooling/silencing-related capabilitites of the boards. I would like to know how many fans can be connected, if the connectors are 3- or 4-pin, and if there is a way to control the fan speeds (preferably via SpeedFan). I don't care about a one-percent performance difference. My first priority is a reasonably silent system.goinginstyle - Monday, October 23, 2006 - link
He mentioned the number of fan headers on each board and even added a couple of comments on the ones that did not work right. In the features section there was a statement about whether the included utility worked or not. Sure he did not say anything about SpeedFan but how far do you want a guy to go after 26 pages? Also, if you click on the Enlarge picture on the boards you can clearly make out whether the fan headers are 3 or 4 pin.
