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.

The DS4 will be reviewed. Gigabyte has stated they will not bring it into the US but we are still trying to convince them (really more like begging and calling our marketing rep at home on the weekends to beg some more) to release it in the States. The copper backplate can be removed off the DQ6 and I really did not see any benefit with it on in testing. It makes for a good rebate with the price of copper today. ;-)The AHCI issues stay the way they are at this time. It is frustrating to say the least. I was being a bit sarcastic in my statement but it is a little harder than it should be to enable AHCI on the ICH8R.

I'm in Taiwan, so the DS4 is all over the place :)Capt Caveman - Saturday, October 21, 2006 - link
Not sure if you live in the US or not but Gigabyte is not bringing/selling the DS4 to the US.Also, the copper backplate for the DQ-6, can be removed with a tworx(sp?) screwdriver. At XS, many just went to Home Depot and got longer screws for their HSF.

Excellent review that'll help potential buyers enormously. A couple things:1. Error in the chart (page 14): There is a discrepency between the chart (3-4-3) and the commentary (3-4-4) :)
2. In memory review Wesley always put tRP ahead of tRCD, while Gary does the opposite. It'd be nice to have a consistency for less experienced users!
3. Gary, did you test the P5W-DH with wirless module installed or without? I recently found out the wirless module could skew CPU/memory-sensitive benchmarks on this board big time. I'm not sure if my finding is true in general, but if it is, then the comparison between a board with such feature and a board without it can be unfair.
4. Can Sandra Unbuffered be really an indication of general performace? @400FSB, setting memory ratio 4:5 (DDR2-1000/4-4-3) boosted the score by a whooping 400~500 MB/s from the ratio 1:1 (DDR2-800/3-3-3), which never realized for other tests in a meaningful way. Oh this is about my own testing. :D
Thanks for the great review.

Thanks for the comments.1. The timing error is corrected. Jarred and I were editing at the same and we found out after the article went live that our saves to the final copy would overwrite each other. Bad timing for several other mistakes that have been cleared up now.
2. Wes is wrong. Just kidding, we will get on the same page. :)
3. I turned off the WiFi on the PSW-DH. The scores were even worse with it on. Not that they are bad but the board runs a little looser timings in order to overclock at the high end. DFI also does this with their boards targeted for the overclocking market.
4. Sandra Unbuffered can be an indication of performance in apps that are memory sensitive. This is not always the case but it is one of the better yardsticks available at this time.

Do you plan on comparing the Gigabyte DS3 vs the S3 version for us to know if there are performance/overclocking issues with the S3?The only difference so far between the DS3 and S3 is "All Solid Capacitors".
Are there any other difference I'm missing?
The S3 is $110, and the DS3 is $150.
I have a hard time to justify paying an extra $40 for only "all solid capacitors"
The term is nothing but marketing to me so far.
I haven't seen any proof of a performance/overclocking issue between the two boards.
If you or anyone else plan on testing the differences or can provide something(Ex: any review link) stating otherwise, that would be great.

In theory, cleaner power.... but aside from the theory, the onboard sound does start flaking out the higher you go. This has been true on 2/2 boards I've tried it on. So an add-in card is needed for the higher overclocks... 460+ish.goinginstyle - Monday, October 23, 2006 - link
No issue here with the Biostar board at 500FSB and the Realtek ALC-883. It sounds fine but a X-FI is still the way to go for gaming.Gary Key - Saturday, October 21, 2006 - link
Yes, the S3 will be in part two. :)
Lothar - Saturday, October 21, 2006 - link
The only other differences I found were RAID support and 2 extra USB ports...It's not worth the $40 price difference if performance and overclocking results are the same IMO.
