Hello,
My system memory card died recently and I think it was because of Kaspersky since there real time protection can be taxing on low memory cards, so I got it replaced through my extended warranty but if I keep it as is I'm betting kaspersky will kill it again.
Right now I have 1 crappy Hynix 1GB DDR PC3200 DIMM,Q card in, and four slots total for up to 4gb total.
I want to replace that with 2GB cards (1gbx1gb) to take advantage of the dual channel also.
So I was wondering do you have to have only two or four cards of the same specs for the computer to work or could I have the two new cards I get installed along with the hynix one to make a total of 3 cards at 3GB, or would that ruin the dual channel advantage or not let the computer function to it's potential?

Also the replacement Hynix 1gb seems to make everything 30% to at times 50% slower then the cards I had that died which were 2 x 512mb samsung ddr pc3200 cards, is that because they were able to take advantage of the dual channel technology?

Thanks a Bunch

Could you supply make, and model of your computer?
If a custom build, make and model of the motherboard.
Does your motherboard support dual channel?

To take advantage of the dual channeling, I'm pretty sure that you DO have to have an even number of dimms. However, the advantage you would see should be overcome by sticking a third 1GB dimm in your system. 3GB running normal vs 2GB running dual channel......you shouldn't even notice a difference.

And, I doubt Kaspersky had anything to do with the dimm burning out. Low end memory just isn't made to the same standards as some higher end memory. I've got 2GB of low end memory in mine that have worked great for over 2 years now, but I've seen other low end memory last less than a couple of months.
What's more irrational--a guy who believes in a God he cannot see or a guy who is offended by a God he doesn't believe in?

It has the nforce 410 chipset which supports dual channel memory up to 4gb
But it only supports the older ddr 400mhz pc3200 dual channel type

My Athlon 650 system is going on 8ish years old (it was donated to me) still running on the original memory. I have no Idea what kind it is though.

There are some manufacturers out there that have a "Value" line of modules which may not perform well under source intensive applications. Another thing to remember is that every manufacturer will experience a failure, it's part and parcel of the system.

Dual channel requires the module to be in pairs, two modules, or four modules. The do need to have the same specs for proper performance.

If you download SIW and open it, scroll down the list in the left margin to Motherboard and click on this. Please post back here what the model is.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.
