That one got me too, check the link I posted;

VERY IMPORTANT INFORMATION REGARDING AMD AM3 CPU's and RAM SPEEDS

Go to page 2, first post, he clarifies ganged and unganged.
It is how the channels are setup, as one channel or two separate channels.

The dual and single channel mode is how they access the memory controllers.
One RAM card is single channel.
Two RAM cards can be single or dual channel, depends on what slots you use.
Three or four cards and you'll be in dual channel.

Ah, thanks for that clarification. I missed page two entirely.

I'll have to check the next time I boot up. I'm sure I have a setting for Ganged/Unganged, but my board's manual doesn't show it as a BIOS option. I've always run Unganged. It would be interesting to see a benchmark comparison. Maybe I'll run some sometime.

DDR3 ram, shouldn't that come bundled with 3 sticks? Mine did. DDR2 was bundled with 2 sticks.
You should set the mobo bios to the ram manufacturers specs, voltage and timings. All hardware should be tuned to specs.

Your 4850 ATI vid card, I have heard of issues with that series card.??????? Especially AGP cards.

W7 is MS's best OS yet, I would be surprised if it was the OS. Get drivers from manufactureres websites. Double check for 32/64 bit versions.

I game with 64 bit, works fine. 32 bit games run fine. Run dxdiag to check direct X and how your hardware works with it.

I used to have issues with sound that appeared video like, other puters did not like pci sound cards, I have taken too using onboard sound. That leaves pci-e slots for video alone.

When your games crash, what does the blue screen say? Will tell you if its video, sound drivers or somthing else.

DDR3 comes as triple channel (3 sticks) and dual channel (2 sticks) and single channel (you guessed it), depending on your needs. AMD boards, for instance, can use dual or single channel kits, where as Intel boards can often use triple channel kits.

The i8xx and down use dual channel and the i9's use triple channel.

Most AMD DDR3 boards use Dual, I think!

AMD integrated memory controllers have a known issue with RAM 1333MHz and above, some CPU/memory controllers have an BSoD issue that has been reportedly fixed with a RAM voltage bump and using unganged setting.

Have seen this issue resolved by the above fix.
Not all have this issue, but there seems to be quite a few.

Yeah, AMD boards can be a little finicky with DDR3, but usually only if you overclock the RAM. AMD will void your CPU's warranty if you clock your RAM higher than 1333. From my own personal experiences with my AMD rigs, and plenty of research, I have a few rules of thumb I work by...

With the AM3 memory controller, you need to be very aware of the RAM and Northbridge voltage, and you need to run your RAM at their specified voltage to get them to work properly. Overvolting DDR3 RAM can kill the CPU quite fast, because the memory controller is on the CPU's die along with the core and just adds to the excess heat.

AM2/AM2+ boards and CPUs using DDR2 are a bit more forgiving, from my own experience, but you still need to be careful with them.

And you should never run your AMD board's RAM voltage at the motherboard's "Auto" setting, other than when the sticks are first installed. Set the speed, voltage, and timings manually for the best results.

I got a NEW PC (AMD phenom II ddr3 @ 1466 Nvidia gts250) back in April. so far, iv had ONE random reboot (@ 1500 on the ddr). Occasionally flaky, but for the most part, its been very stable for me. I would assume using the same drivers on the same hardware would result in the similar stability. I would try switch to 32bit win7, and just see if that makes a difference. If so, it would most likely point to drivers. I would only revert back to XP kicking and screaming...

I know this is a Windows 7 forums so I do expect some bias, but what OS would you recommend for me that is the most stable and would be able to play new games? I was considering XP 64bit but I read the support for that is terrible. Now I'm considering a 32 bit OS if it would provide more stability but I don't want my 4gb of RAM to go to waste. What do you think?

CPU: AMD Athlon II x3 440 3.00ghz
RAM: 4gb 1333mhz DDR3
Graphics: ATI Radeon HD4850

So I should change the timings to the manufacturer-specificed ones (it was set to AUTO and the timings ended up different)? Earlier on in the thread, someone said I shouldnt mess with the timings....

When people were saying don't mess with the settings, it was more of don't tweak them if you don't know what you are doing or trying to eek out more performance.

Even though I don't have an AMD rig, I tend to try to stick to manufacturer's recommended settings to keep things within norm if possible. People who have the patience to tweak and be willing to deal with quirks will try to up their system, especially if they have much more serious gear like liquid cooling and what not to compensate for Overclocking issues such as heat. AMDs tend to run a little hotter due to design, so you have to be wary of every little thing if you want to get the most out of the system, or risk running into having a nightmare trying to get it to work because of tweaking a setting without knowing you need to have the right circumstances.

Good advice from both the above posts.

What were the timings set to, when on Auto?

If you don't have CPUZ, you should D/L it and post the memory and SPD tabs.

Sometimes AMD boards will lower settings in order to have better stability.
They sometimes don't run well at 1600MHz, it will be more stable at 1333MHz.
They will have a JEDEC setting for 1333MHZ on the CPUZ SPD tab.

If that is what your referring to, you should leave it at 1333MHz.

From the previously posted link.

Quote:
Some of the Athlon CPU's have a memory speed rating of 1066 Mhz and will pull back RAM above this speed to the default setting. This is again to protect the CPU's Memory Controller and is not a fault with the Motherboard, BIOS or RAM.
So it may need to be at 1066 MHz.

Did you check if it is in unganged mode?
