My CPU has fsb of 1066mhz and my memory is supposed to to run at 1066mhz, but is running at 800mhz. I have noticed some cpu not doing well in futuremark tests and am wondering if it is bebecause the fsb and memory do not match.

More about : memory

Running the memory at 800 MHz instead of 1066 MHz has a negligible impact. Other than Futuremark tests, is the system running fine?

Not very well. games are not running smoothly. I am running windows 7 and there isn't a motherboard driver available for me as of now. asus says it will be soon. I did find on my device manager that a coprocessor was running because it did not have a driver. do you thing that is what the problem is?

What do you mean by a coprocessor? Why not post your full system specs?

I couldn't find info about that motherboard (Asus don't seem to have an MN3-HT motherboard). What chipset does it have and aren't drivers available from the chipset vendor?

Have you tried the nForce drivers available from NVidia?

nothing available for win7 at this time. what does a coprocessor do and could it cause my games to not run smoothly?

I went to nVidia and I searched for:

Product Type: nForce
Product Series: nForce 7 Series
Product: nForce 780a SLI (is this correct for your motherboard?)
Download Type: Driver
Operating System: Windows 7 64-bit

I can't tell if they actually work or not for your system.

It depends on the coprocessor. Is it on the video card or on the motherboard?

the device manager did not say what the coprocessor was for. 780a sli is the chipset. will it matter that it is not the driver from asus?

Asus get the drivers from nVidia, they don't write them.

I just thought to tell you my cpu's front side bus is 1066mhz and my memory is only running at 800mhz. those new drivers did not work so I thought maybe this has something to do with it.

Definitely not. If the downloaded drivers didn't work, new ones will hopefully be available by the time Windows 7 is released. It sounds like Windows 7 RC drivers probably are easier to get for Intel and AMD chipsets.

Everything was working very well until I upgraded from my dual core to the quad core. I was really looking forward to the increase and instead it actually slowed down gaming.

Depending on the model, games should run about the same.

If the Quad has the same processing power per core, then it should behave the same (except for a little extra overhead to manage more cores). Since you only swapped the CPU, why did you need new drivers? That doesn't quite make sense to me. In Device Manager, Processors, you uninstalled the Dual core and the Quad core has been properly detected?

I really did not know what I needed, so I just started with the drivers. The first thing I had to do was update the bios. the old cpu ran fine under the original bios. after that I noticed it was not doing better in the 3dmark tests and it was actually doing quite a bit worse. that is when I started trying to figure out what was causing it to run the way the way it is. i thought drivers because the cpu and motherboard were fairly new. then I thought it might be the memory because it was running at 800 and the cpu fsb is 1066. so right now I am really stumped and considering reinstalling windows xp instead of 7 to see it that does any good. any suggestions?

Other than the BIOS update and the new CPU, anything else has changed since the system was running fine? Can you reinstall the old CPU to see if the problem goes away? Before buying the Quad, did you check the charts to make sure that it would actually be faster?

It was supposed to have a big improvement, because of the 3 levels of cache and a faster front side. just a thought, could a power supply have anything to do with it? I have an antec 650w. this cpu does require a lot more power and it does start messing up when i am pushing it.

A 650W should be powerful enough, but it depends on what else you have in your system. Do you now have a Phenom II X4 945? What do you mean by "it does start messing up when i am pushing it."? Are you overclocking it to the max?

Just when i start playing a game that is new and requires a powerful pc. I don't overclock very often. just haven't found a need to do it. I have 2 dvd burners, 2 harddrives, many, many fans and the gtx 275

You can use Antec's PSU calculator to determine if your PSU is powerful enough. Fans normally don't require much power.

Just checked and it may very well be the psu. it said required watts was 683 running at the 85% which is was the recommended setting

i checked something I should not have and the power is not the problem. this weekend i'll go with winxp and see if win 7 is the problem. If thats not it, i'll start to think there is a prob with the cpu

I just wanted to let you know that it was the cpu not working with the motherboard. for some reason only one core was being used. I put my dual core back in and both cores are working fine. I am assuming there is a bios update needed, so i'll just have to wait for it.
