AMD Dual Core Optimizer won't execute

[T3kl0rd]

The AMD Dual Core Optimizer has stopped executing when it is supposed to be running. It is set to run on startup but exits out every time. I can't execute it when I run the executable either. I need it to run because games like Batman: Arkham Asylum and Street Fighter IV don't run well without. The difference is night and day with it running. Can anyone help me get this running again? Thanks all

I didnt think the Dual core optimizer had to be installed with windows 7????

Is it version 1.1.4?

 

[T3kl0rd]

The latest one, yes it is. Yes, it has to be installed and it makes a world of difference with my dual core. It mysteriously stopped working and I don't know why

 

[Melvis]

Ok righto, fair enough, thats good to know for me as well

For your problem i have no idea sorry

I would just uninstall/reinstall make sure all the files have been removed before reinstalling and see what happens?

 

[T3kl0rd]

I did uninstall/reinstall and it does the same thing when I do. Where would I look for residual files from this to clean before reinstall?

From what i know this tool was only needed on Windows XP. Vista and 7 shouldn't require usage of it.

Everyone says that but Street Fighter IV and Batman: Arkham Asylum run like poo without it. The difference is huge. Those games run flawlessly with it and the frame rate is in single digits without it.

that sounds like a problem with your system, as opposed to a neccesity of the program.

If the game didnt work on dual cores for everyone, i'm sure we'd have heard of it before now.

It still runs okay on my dual core, but I have to turn the settings down from everything maxed for it not to lag like crazy. With it running like it should, those games run like a dream. People may not understand the difference it makes in those games that run dual cores. I read over in the Capcom forums, the AMD DCO fixing their lag problems in SF IV so some do.

I'm pretty sure the Dual Core Optimizer is only for Socket 939 dual-core processors and early AM2 processors (65nm Athlons). Your Phenom II shouldn't need it at all.

actually its not hardware locked at all, it was just meant as a fix for XP's poor handling of dual cores (Intel had less issues, due to unknown reasons)

the fact that its still needed on vista/7 is what surprises me.

The problem was the RDTSC (Read Time Stamp Counter) in early dual-core Opterons and Athlon X2 processors. Each core in the processor would increment the time stamp at its own pace which ultimately lead to them getting desynced. The Dual-Core Optimizer (which isn't an optimizer at all; it is a hot fix) periodically makes sure all RDTSC return the same value so they remain in sync.

It was a hardware bug which is why Intel never had that problem. They got it fixed in a later revision (Intel doesn't say which processors are affected on their site, unfortunately). If your processor has more than 2 cores, it doesn't need it. If it has two cores, it may, or may not need it depending on how old it is.

No Phenom or Phenom II needs it, even on XP. The defective chips were all in the Opteron and Athlon X2 lines.

Windows 7/Vista still need it on those older processors because the problem is still there.

it also did more than that, i recall reading something about it helping to arrange applications between the cores better, preventing two high needy threads being on the same core with unused power on the other. that sounds like what is helping in this situation.

It does no such thing. The name of it is marketing spin. They wanted to make people "want" it rather than realize AMD screwed up bad and you "need" it. Note how it only mentions the RDTSC issue on the official page:
http://support.amd.com/us/Pages/dyn...cd2c08-1432-4756-aafa-4d9dc646342f&ItemID=153

It's a bug fix, not an "optimizer." They lied.

With the difference in the games I mentioned, I would have to say this is the scenario that still is taking place with AMD's cutting edge dual cores.

I'm thinking some Windows updates may have knocked it out.
