AMD Overdrive Utility Improvements

We utilized version 2.1.2 of AOD for our testing. This new version will be launching next week with the product that we dare not mention its name, but it does include the new SB750 and a smoking hot IGP core. This version of AOD has matured nicely from the 2.1.1 beta we have been using the past few weeks. The major enhancements include ACC capability, IGP GPU clock options, new color schemes, skinning ability for the OEM, system diagram and individualized component information, and additional tuning options dependent on BIOS support.

Appearances are everything...

The old...


The new...comes in any color you like as long as its red or black.


 

 

Same old Performance Control face but with more options now...

 
 
 

New System Diagram Interface with all your favorite reporting tools rolled into one...

AMD has added a new feature that allows you to get instant and usually detailed information on the system platform and components attached to it. We found the information provided to be very detailed and quick to reach with AOD open. It might not replace your favorite tools like Everest, CPU-Z, or GPU-Z but AMD has provided this type of information in a single user interface now.




We have included additional screen shots in the following gallery.  

Test Setup-



Our test setup consists of typical component choices we feel an AMD enthusiast user would probably choose for their own system. Our Corsair 1000HX power supply is probably over the top but will be required for Quad CrossFire testing in our next release article. Also, as we delve more into AMD overclocking, our cooling system will have to be upgraded and our first choice is the CoolIT Systems Freezone Elite.

How it Works, um, Kinda Testing the Theory - Does it Overclock Any Better?

    This article claims the PCIe slots are 1.x when they are in fact 2.0 as stated in the manual, website and other sources.

    Just wanted to make everyone aware of this. There are four total PCIe 2.0 that can run 2x PCIe 2.0 cards at x16/x16 or 4x PCIe 2.0 cards at x8/x8/x8/x8

    To get around this, get an X2 version of the Radeon HD 3870 or 4870 and then crossfire with another one or drop down to a standard 3870/4870

    Anyone see AMD OverDrive 2.1.2 available for download yet? It's Wednesday the 6th, official release day of 790GX+SB750.

    "it's unclear whether or not whatever AMD is doing here can even work on K8 if they tried."
    Nope. I've been waiting for a board/BIOS maker to expose this chipset setting since the Athlon XP Mobile Barton CPUs first made me aware of it. My Mobile Barton Athlon XP was basically a completely unlocked bin-sorted Athlon XP 3200+ that was stable at lower voltages expected to be run at much-lower voltages and clock speeds.

    With it, I discovered that there was clearly a chipset setting not exposed when my Mobile Barton failed to reach 200/400FSB in an nForce2 Ultra400 board (the Shuttle board inside my SN45G XPC... the FN45-whatever IIRC) while the same CPU could easily do 450+FSB in an Asus A7N8X-E Deluxe and an Abit NF7-S. The solution? Drop a thin wire inside the socket to make this completely unlocked CPU *DEFAULT* to 400FSB and it runs perfectly fine and can even go higher (the L12 trick/mod).

    With the default FSB being the only difference (all settings/frequencies, including the FSB, were the same), it was very clear that it was related to a calibration setting that was automatically applied by the chipset based on the default FSB (100MHZ/200FSB for this unlocked CPU). Previously, I could only get to 333FSB before Memtest 86+ would start giving errors. There were some reports of even the overclocking boards (mentioned earlier) getting higher with the L12 trick and later many had BIOS updates and board revisions that seemingly integrated the trick. Regardless, the setting was still not exposed and was likely not even something the board/BIOS makers could expose (though they could spoof the default FSB I'd assume). It looks like AMD, having full control of chipset and board-level options here, has finally let the cat out of the bag.

    Although the FSB has become the HT bus, the behavior is the same. Changing the calibration setting allows for higher clocks while actually becoming unstable at lower clocks. Ever accidentally erased the OSCAL calibration value on a PIC microcontroller and had to find a working value through trial and error? I'm guessing that this is why it was automatic before.

    Leads me to suspect that ACC is a means of adjusting the substrate potential to provide a bias to the bottom of the SOI stack to control the threshold voltage of the transistors.

    To spread the word: http://ubuntu-virginia.ubuntuforums.org/showthread...

    | To be honest I find it hard to believe that they have a campaign
    | against Linux. There would be nothing to gain and would have
    | a zero fiscal gain.

    | I think it is a bug you have found

    After looking through the disassembled BIOS for the last several hours, rebooting it, and tweaking it more, I'd say this is very intentional, I've found redundant checks to make sure it's really running on Windows, regardless what the OS tells it it is, and then of course fatal errors that will kernel panic FreeBSD or Linux, scattered all over the place, even in the table path for Windows 9x, NT, 2000, XP, and Vista, and had to correct them (Well, at least divert them off into a segment of RAM I hope to god I'm sure about)

    No, this looks extremely calculated, it's like they knew someone would probably go tearing it apart eventually and so tried to scatter landmines out so as to where you'd probably hit one eventually.

    So if it is a mistake, or incompetence, then it's the most meticulous, targeted, and dare I say, anal retentive incompetence I've seen.

    I've never had much faith in Windows OC tools.
    However if this one actually works and AMD can up their speeds a little then I may switch back for my next system.

    I must say my 6400-8400(cheated got an e3110 with 20% discount when first released and they were all $280 or OOS for $170). Upgrade path was seamless and I feel bad going from 1950Pro to 8800GT 512 but I follow my wallet not the company I root for.

    A cheap system built off cheap Black Box edition(OC'd easily with their tool) and 4870x2 would be pretty sweet come this December if the new cores are kicking and the utils work(a lot of ifs). Not that I need a new system though, but if one did. I don't see nehalems being affordable anytime soon(unless new AMD core rocks(another if)), although my mobo would support. I like the $200 mark for processors $100 for HDD's $200 for gpu's plus generally only needing 1-4 new parts for a yearly $400ish upgrade which is cheaper and allows better performance than the $1-2k some people build.

    Does anyone know when they will release more info? Gary? Any estimates of when to expect another article? Or will we have to be in suspense all weekend.

    I am really hoping that AMD can make some competition on CPU market as they did on the IGP (man i am really looking forward to the next IGP offer from AMD, the 780G is the king, the next chip will be a market consolidating move for sure)and VGA markets but i am not joking when i ask:

    Will a 3.1Ghz ultraoverclocked quad core Phenom beat a $80 E2180@3,1Ghz in gaming and common day tasks?

    As i remember the C2Ds are 15%-25% faster clock per clock, and the AMD CPUs consume MORE power for the same tasks , because they take LONGER to do the same task of a C2D.
  • jslusser - Thursday, July 24, 2008 - link

    So does this ACC on the SB750 do anything for vanilla Phenom's? Will it unlock the multiplier on the non-black Phenoms or just make them more stable with the HT and memory over clocks?

    I'd like to see where the 9150e/9350e can get to with ACC and the power usage, since the voltage, etc doesn't change. So many questions...
  • HazaroudsSmoker - Friday, July 25, 2008 - link

    First, you can't unlock the multiplier on the non Black Edition Phenoms. They are locked at the factory during manufacturing and can not be altered.

    Sounds like there will be an advantage still to having the SB750 with Vanilla Phenoms.

    Can't wait for Benchmarks.
