Intel P965: Mid-Range Performance Sector Roundup

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.

Re:So, how about the (yet unreleased) ATI and NVidia Conroe chipset boards?
Does either chipset include PATA support?
Thanks.
Gary Key - Saturday, October 21, 2006 - link
They both have native support for two drives.

Gary, always love your reviews!I read thru the whole thing, & it was a good read :)
Meticulous detail, as well great sarcastic humor as well.
I look forward to the following parts.

In an earlier AnandTech article, the one about Kentsfield support, it was written that Gigabyte would bring a revision 2.0 of all of their P965 boards to the market in mid-October, including the DS3. The article does not mention whether the board tested was this new rev 2,9 or any other. Could that be clarified?And does anybody know what was changed/fixed in 2.0?
Gary Key - Friday, October 20, 2006 - link
Gigabyte has not released any further details on the revision 2 boards except for the fact they were addressing some layout issues and possible BIOS improvements. The only major change we could see them making would be going from a three phase power design on the DS3 to a five phase system as an example. The board we tested is still revision 1.Sho - Saturday, October 21, 2006 - link

'caliper' should be caliber on AB9Pro pageGreat work on this roundup though, impressive job.

Which board? The topic of the previous page was about sound cards vs. onboard audio. Is there a missing page? Why is there a picture of the Asus heatsink and no mention of which board is the preferred of the bunch?Just some questions =)
Great article for Cost/Performance comparison.

Woah, there's a lot more there now. Thanks for the explanation.I just built a workstation for a client using the 965P-DS3, but the board was DOA. I went to a local shop and picked up a 965P-S3 instead (seeing as how the only main feature missing was the solid capacitors of the -DS3), and it performed just as well as the DS3. For $110, a GA-965P-S3 would be the best Cost/Performance of the 965P bunch, in my unresearched opinion.

Now you're skipping ahead to part 2! :p
