Overclocking Comparison

Maximum overclock data was added to Performance graphs beginning with the nForce4 SLI roundup several months ago. The overclocking performance graphs should allow better comparison of the overclocking capabilities of tested boards. For more details on the specific overclocking abilities of a specific board, please refer to the Overclocking and Memory Stress Test section of individual board reviews.

Overclocking

The overclocking performance of the ULi M1695/M1567 Reference 2 was impressive to say the least - even more impressive than the excellent Reference 1 ULi board. 242 Clock Frequency at stock multiplier is one of the highest overclocks that we have ever seen with this reference processor.

400 at the lower 7x multiplier is truly amazing, and it is the highest value that we have reached in any testing. Keep in mind that this is not our standard base DDR400 overclocked, and is not directly comparable to past results. Therefore we did not include a performance graph with the 400 value with lower multipliers. We always test to see the highest value that we can reach on any board before settling back at the DDR400 overclock. The ULi is just amazing to reach 400 CPU Base Clock in our tests, which certainly indicates a robust voltage regulation with this chipset. We are very happy when we reach a 50% CPU Base Clock OC (300) at lower multipliers. Reaching 100% Base Clock Speed OC (400) is rare.

ULi's claim that a base clock speed of 400 was possible met a lot of skepticism here, but the board did exactly what ULi promised. To be fair, it is mostly just a bragging point and has little impact on performance until ULi also implements the companion vDimm adjustments and expanded vCore to make 400 a true performance booster, but it is still impressive.

    Someone may have asked this, but I didn't see it, my apologies if this is a duplicate. But will these boards support AMD's dual core chips?
  • ElJefe - Saturday, August 20, 2005 - link

    Not only will it support it... it is the only one out that DOES support it truly. It needs no bios revision, it is built into the original bios to support it. asus, gigabyte and abit all warned me that it is highly likely that if you purchase any of their boards and put a dual core cold on them as a new system, the computer wont "post" and just sit there. youll need to buy a 939 chip or borrow someones if it isnt this m1695 asrock board. really, there hasnt been much growth since this has been reviewed in boards, so none have put the dual core bios as their official starter/tested/stable bios yet.

    and from reading 100's of legitimate forum entries from all 3 of those main companies, i can say that I would never do dual core without going for a board that is brand new. the problems and conflicts are rather universal and rather pathetic.

    I am not sure why there isnt talk of this much in forums around here, but if you read the forums of those places you will see obvious problems (abit is the worst at the moment though, which is most unfortunate as they were my favorite company for many years)

    I'm not sure if someone asked this...but is it possible to use existing AGP card and PCI-e card on the same board with Crossfire for example with this chipset? Let's look at this like this. I have an AGP X800XT PE now and I want to buy a X850XT PE Crossfire edition in PCI-E and put both in the motherboard that comes out with this chipset. Possible?

    nVidia has sent us the following information:

    "The ULI board isn't certified for SLI. It hasn't been submitted."

    nVidia added that modified nVidia drivers generally indicate a board that is not certified.
  • nserra - Monday, August 8, 2005 - link

    Well it isn't selling any way, why certify it?
  • ElJefe - Tuesday, August 9, 2005 - link

    just a tip:
    someone said that Asrock usa isnt going to sell this mobo in the US of A, that is not true, i called today and it definitely is going to be sold here very soon.

  • mino - Saturday, August 6, 2005 - link

    Actually this is understandable. Why bother to certify an preview board ? For a company like Uli this would be a waste of time and money.
  • deathwalker - Saturday, August 6, 2005 - link

    I'm looking forward to the release of Mobo's on this chipset. I want to upgrade to a socket 939 system and at the same time be able to keep costly components that I have(6800gt agp card for one)for use in it. I hope we se a micro ATX version that I can drop in a Aspire X-Qpack case. Good job Anandtech for picking up on this upcoming release and covering it for your dedicated subscribers. I don't think Tom's Hardware even knows this exists..not a whisper on there site about this chipset.

    Not really because I already bought a AN8 Utlra.. A, as in Abit. That's really what ULi needs for wide-spread adoption.. ABIT/DFI/ASUS/Gigabyte/MSI branded boards with wild OC options.. not Asrock/tul/ECS. I waited and waited for a decent SiS755 board which was also very promising.. which never came. I'm betting the same will happen here, especially so now that board makers have to make room in their stable for ATI based chipsets.
  • nserra - Monday, August 8, 2005 - link

    But Uli offers AGP 8X, no one does this, so they will be “forced” to support it.
