Disk Controller Performance
The AnandTech iPeak test is designed to measure "pure" hard disk controller performance, and in this case, we keep the hard drive as consistent as possible while varying the hard drive controller. The idea is to measure the performance of each hard drive controller with the same hard drive.
We played back our raw files that are recorded I/O operations when running a real world benchmark - the entire Winstone 2004 suite. Intel's iPeak utility was then used to play back the trace file of all I/O operations that took place during a single run of Business Winstone 2004 and MCC Winstone 2004. To try to isolate performance differences to the controllers that we are testing we use the Seagate 7200.10 Barracuda 320GB 7200 RPM drive in both SATA and IDE offerings for our tests. The drive is formatted before each test run and a composite average of three tests on each controller interface is tabulated in order to ensure consistency in the benchmark.
iPeak gives a mean service time in milliseconds; in other words, the average time that each drive took to fulfill each I/O operation. In order to make the data more understandable, we report the scores as an average number of I/O operations per second so that higher scores translate into better performance. This number is meaningless as far as hard disk performance is concerned, as it is just the number of I/O operations completed in a second. However, the scores are useful for comparing "pure" performance of the storage controllers in this case.
The performance patterns hold steady across both Multimedia Content I/O and Business I/O, with the NVIDIA nForce 500 based SATA controllers providing a slight improvement in I/O operations over the Intel, JMicron, and Silicon Image SATA controllers. This has been a historical trend between the manufacturers with the NVIDIA controllers generally having a fractionally higher throughput than the other chipsets. We look forward to seeing how well the ATI SB600 will perform with an Intel processor in the upcoming DFI ICFX-3200 based on the RD600 chipset.
Of note in our SATA tests is the excellent performance generated by the JMicron controller logic that scored higher than the Intel ICH7R or ICH8 based SATA controllers in the Business Winstone test. However, in the read and write heavy Content Creation tests we see the Intel SATA controllers placing ahead of the JMicron offerings. After reviewing the test script results we noticed the write operations of the JMicron JMB363 chipset was about 3% slower than the Intel ICH chipsets while being around 2% faster in read operations.
The VIA VT6410 controller offered the best performance in the IDE tests with the JMicron JMB363 finishing last. During initial testing with the JMicron chipset we noticed several boards having issues with the optical drives being stuck in PIO mode resulting in terrible performance. However, this issue was solved with recent BIOS updates from the motherboard suppliers. We also advise that unless you utilize the JMicron JMB363 for RAID operation then do not load the JMicron driver or allow Windows Update to install the newly released driver. Installing this driver will usually result in sporadic operation of the IDE port or failure to recognize certain optical drives.

The biggest problem I, and seems like most, have with 965 chipsets is the JMicron JMB363 IDE. You said there is a driver problem for the newwest driver but did not say what driver that is? Like 13.03, 15, etc... I think I have a new driver then someone in the forums has one that is 2 whole numbers newwer.I have a hard time trying to find a decent driver so I just get what I can for the JMicron JMB363. My DVD burner just comes up in windows as a reg. drive and I can;t get windows to see that it is a burner. Mind you Nero sees it as a burner. So I am guessing that is a JMicron JMB363.
I like my Gigabyte board, better then the Asus I had. But the lack of IDE support by Intel makes me want to get a Nvidia 600i board even more.

The Biostar 965PT (and, I assume, the Deluxe) includes a VIA VT6401 IDE controller instead of the Jmicron. I had no problems seeing the controller in the BIOS or getting my optical drive to run in DMA.Just another reason that this board rules.

The biggest problem I have encountered seems like a small one, but it's getting annoying.It seems that none of the 965 boards allow for 2 x PATA connectors...I don't know for sure, but I assume this is a limitation of the chipset.
The problem I keep running into is the reuse of existing components for an upgrade. Obviously you need one of the PATAs for the optical drives, which means that unless you get a PATA controller card you can't reuse your existing PATA drives...

The P965 chipset doesn't have any PATA support by itself, so the mobo makers need to include a seperate controller.BladeVenom - Thursday, November 9, 2006 - link
Nice to see the less expensive models getting a thorough review. Everyone reviews the Biostar Deluxe, even though it's almost impossible to find, unless you're a reviewer.Also nice to see that model of Crucial RAM used. Next time you do a budget review could you also test the cheapest memory available, and 1:1 ratio for overclocking be damned.

We are still testing lower priced memory. I will add some addtional overclocking results to these two boards tomorrow. :)

I might have missed the reason for this in the write-ups. If so, I apologize. But, why aren't you reviewing any Intel boards? I'd have thought that they'd provide a decent baseline for comparison to see if the other manufacturers can do any better/different.Gary Key - Thursday, November 9, 2006 - link
The Intel board we originally received has been pulled from retail availability. We have a BLKDP965LTCK coming next week to take its place. I believe this board currently retails for $110~$115. I will do my best to at least get performance numbers from this board in our charts before the final article goes up.Sho - Thursday, November 9, 2006 - link
... where's that high-end board roundup hiding? IIRC an Anandtech staffer had announced it for last Friday in a comment to another article about two weeks back.
