QX6700 Quad Core Overclocking
Quad core overclocking on the P35 platforms has turned into a pleasure with the latest BIOS releases from each supplier. The MSI board reached a final 365FSB that we found to be extremely stable during testing and places it at the top of our P35 grouping. Of note, our processor will actually do 3920MHz on water with 1.575V but we reached the limits of air cooling at 3650MHz. Our memory timings once again had to be set to auto with slightly relaxed CAS timings due to the aggressive chipset and memory latencies that MSI implements on the board.
We dropped the multiplier on our QX6700 to seven and were rewarded with a final 7x465FSB setting compared to a 7x422FSB with the P01 BIOS. However, that is the current limit as we ran into stability problems with our system at anything above 466FSB with the quad core. MSI believes there is a little more left in this board and is currently working on extracting additional performance. We hope to have an update shortly but for now this is the maximum FSB on the board with the quad core. We have reached 540FSB with our E6600 in preliminary testing so the board is certainly capable of the 535~550 FSB range with the right processor, although we have to run the 1333 strap over 500FSB to ensure application stability.
We changed the multiplier on our QX6700 to eight and reached a final 8x460FSB setting that was limited to air cooling. We had to run on the 1333 strap as the memory/chipset latencies are set a little too aggressive on the 1066 strap above 440FSB. The board ran fine on the 1066 strap at 460FSB with the quad core in most instances. However, Quake 4, Prey, and Nero Recode would constantly crash until we backed off the FSB or changed memory straps.

I read a lot of things about this board from may till july test's and a lot of peoples are disapointed but I buy MSI P35 Platinum Mboard also and got 1.1 rev with 2GB of Kingmax 1066 MHz and E6750 Core 2 duo and everything I can say is that this board is rock stable at 500 MHz FSB and 1:1 memory at 1000MHz 7x multiplyer and CPU at 3500 and all that at every DEFAULT VOLTAGE, I succed to load windows at 520MHz FSB but test failed after 20-30 seconds but I didn't raise any voltage at all.Sow some post on forums some suced to boot this board at 700 MHz FSB and air cooled rock stable at 600 MHz.
Look's like they changed a lot of things in 1.1 rev or CPU have big difference, dunno but I'm satisfied!

I forgot to say, memory was at 5-5-5-18 and in Everest I got 9345 MB/sec memory read benchmark.TA152H - Tuesday, June 26, 2007 - link
It's a pity they waste that roller coaster on obsolete memory like DDR2. On top of that the excellent latency makes this an attractive (in two ways) motherboard. Except it's shackled with obsolete memory. What a nuisance. Any idea when they will have a DDR3 based motherboard out? Why even bother reviewing obsolete motherboards? Everytime I question the merit in some reviews, I'm always told it's an enthusiast site, so, why bother reviewing obsolete motherboards and instead go straight to DDR3 1333 motherboards? Will anyone want this backward technology when Conroes running with a FSB of 1333 are available, or as DDR3 latencies continue to drop quickly? DDR3 1333 is already beating 1066, at much lower voltages, even with higher latencies than are available. It's only going to get worse. DDR2 was a sucky technology, it's time to move on.coldpower27 - Wednesday, June 27, 2007 - link
Because for the moment, DDR3-1333 still costs a small fortune with prices close to 400 USD for a 2x1GB kit, for these marginal performance benefits, at that level, you can simply spend the money on a faster processor 1 grade higher.You can get 2x1GB of DDR2-1066 for 150 USD give or take and that is already pretty close in performance to DDR3-1333.
This is an enthusiast site, but that doesn't mean they don't review mainstream level products, Core 2 Duo E4xxx would be a good example, as well as the Athlon x2 BE-2350, Geforce 8600's.
If you can afford to purchase DDR3 memory, you can afford to wait for the enthusiast X38 chipset.

You're wrong of course.Why would I want an x38 chipset? I don't intend to use two video cards, and it's unclear if x38 would have any performance improvement. After all, P965 was at least as fast as the 975. So, I'd buy whichever one used less power. Also, the whole premise that if you have money to buy DDR3, you have time to wait, is absurd. They are unrelated, there are plenty of people that need something now that have money. That's a severe logical error.
The performance difference is greater than they indicate on this site. They have an agenda of some sort, I think, because they test DDR2 memory with timings that are spectacular, to say the least, but test slow DDR3 memory. The FSB 1333 was bizarre too, they didn't even test it with DDR3 1333 memory. Something is wrong with their choices, for sure, its like they are actively trying to thwart DDR3 because someone or another has decided it's not ready yet. Give the results, and let people decide for themselves.
Most people don't need 2GB of memory anyway, and you could easily get by with one and get other memory later when you actually needed it. Besides, most people will wait for the 1333 Intel processors to come out before they buy this type of motherboard, and by that time latency and price should drop.
These sites are supposed to be forward looking, not backward. DDR2 is obsolete, motherboards using it are obsolete, and it's time to move forward.

Ha, I am right of course, and it is logical that if you have that much to spend on computer components, you can get better performance and more of it, by easily spending on the video card or CPU, $200 more in those places will give you considerably better performance. Memory performance is just secondary to those and gives less gains on the whole.975X vs 965 memory performance is moot as 975X is based on older chipset technology skewing the results. X38 and P35 are based on the same generation of chipset ICH9 so X38 would indeed be faster.
Most people don't need DDR3-1333 now either, and if you really want to upgrade to DDR3, simply get a hybrid board and use DDR2 now and get DDR3 later. Memory has always been one of the factors that just don't generate enough performance to be worthwhile, and only a nice to have.
Depends on what your looking for, if your building a system with a P35 Chipset, then your looking for something with 45nm compatability. The motherboard makers know this and hence have rolled out the DDR2 based P35 chipsets first with DDR3 based ones coming out slower.
If your building a system now there is no point not get a P35 based motherboard based on DDR2 as it's only marginally more expensive if that.
2GB of memory is much more useful now then faster memory, especially so now with the advent of Windows Vista.
DDR2 still has alot of life left in it, it will take sometime for production to ramp and for DDR3 to displace it. DDR3 based P35 sales will only be a fraction of motherboard sales as it will take quite a bit before memory falls.
In 1 month, DDR3 is largely unlikely to have any significant price drops, or any speed increases worth mentioning.
If you are going for super expensive DDR3 high performance memory, the premise is that you want to spend alot for computer components so you would want a high performance chipset to go with it, hence waiting for X38. Buying DDR3 now is a waste of money, the same money will give better performance if you bought a higher grade processor or video card. DDR3 for mainstream systems now is a complete and utter waste until DDR2 and DDR3 prices normalize or you have no other choice like with OEM systems.

You don't need 2 Gig, and memory really only help performance if you swap. If you don't the 1 Gig will outperform it. And nothing you can do will ever make that 2 Gig faster, but you can add more memory later if you need it.Hybrid boards tend to have lower performance, although it's unclear to me why. But at any rate, I wouldn't waste the money on DDR2 and suffer it's performance.
The remark about P35 and x38 is just ignorant. You are talking about something you know nothing about. I haven't seen anything that would indicate better performance, just more PCI-E lanes. Anything is possible, so I won't say anything as ignorant as you did, and predict performance will be the same. We'll have to see.
DDR3 would have a bigger performance boost in the test if they actually tested the stuff that is out there. They artificially tested it with high latency, for whatever reason, and if they had tested CAS 7 memory which is readily available from a number of makers, you would have seen better results. But, no, they tested artificially slow DDR3, and extremely fast DDR2, and still DDR2 is slower by a noticeable degree. With CAS 7, it would be more important.
You have no idea what will happen in a month or two, but the trend has been latency shrinking fast, and cost dropping. It's probably a safe assumption, but predicting the future is never perfect so, we'll see.

I wish you would have held their feet to the fire about their 975X PUE BIOS. The BIOS for that is still a shoddy piece of unstable crap after a zillion official releases and Betas.redniels - Saturday, October 27, 2007 - link
I 100% agree..I bought this board back in June, one of the primary reasons was the positve review overhere. I wish I didn't, and just bought the asus for that "few dollars more"
I had a terrible time installing this shoddy piece of garbage, not because the hardware is/was faulty, no it was because every bios (Yes: EVERY single one) since the release to market of this board had (and still has)serious issues which make installing an OS and/or flashing the bios something like russian roulette.
I've experienced grave issues with Bios 1.0, 1.1 , 1.2, 1.3 & 1.4

Glad to see you are still planning this roundup. I purchased the Abit IP35 Pro and have been tweaking for some time now. I look forward to seeing how it does against the others.
