1866MHz

Hey,

I am looking, and struggling to find, some decent and affordable 1866MHz memory for my new A8-3850.

I am from England and on all the trusted websites I know from here, there is basically nothing. I know that the Llano chips only supports up to 1866MHz speeds and I also know there is a tangible benefit for buying memory of this speed over 1600MHz, more so than buying say 1600MHz memory with low latency.

So ideally I am looking for 1866MHz @ 1.5v and CL8, but CL9 would do fine too.

My question is, can I just get 2000Mhz mem and clock it down? Will this still be supported by the chip? I know I could overclock some 1600MHz speed mem but I don't want to raise the voltages.

cheers.

I realize that CPU makers tell you the maximum memory speeds like 1333MHz or 1866MHz but the memory CAN be run faster than that. You could get a 2133MHz kit and run it at 2133MHz, you would just need to make sure it isn't a high voltage kit to lessen the load on the rest of the system.

There is a tangible benefit for buying faster RAM, but only with LIano and even then it is mostly for the IGP of LIano.

I don't know if you can use newegg to buy stuff in the UK (Although I bet you can)
but it is all I tend to use. Newegg a 1.25volt 1600MHz kit. You could overclock it to 1.35v for 1866MHz or even 1.5v for 2133 or so MHz if you don't mind overclocking. This would be cheaper than buying a 1.5v 2133MHz kit. there are also some 1866MHz kits on newegg. Either way I suggest you don't go over 1.5v once you are running the computer and will probably need to manually set the RAM speeds and possibly timings.

I want the benefits as I will be using the IGP quite a lot. This system is intended to be an HTPC which I can play a few games on too.

I cant get Newegg stuff in the UK, but could you link me some of the modules you suggested? I might be able to get them over here too.

I have no problem with overclocking just didn't want to be raising the volts too much to save power. If I could get a cheap 1600MHz kit that I can oc with less than 1.5v that would be great :)  Wouldn't want to go higher than CL9 either.

Maybe something like this?

I was thinking these:

These are 1600MHz CL9 but are 1.25v, the ones you looked at are 1.35v and won't overclock as high. for any gaming machine I would recommend 8GB of RAM (this is an 8GB kit) because some games overwhelm 4GB of RAM nowadays.

Hmmm, not much proof that the G.Skill Sniper RAM will oc that well. Most reviews I have read say it doesn't oc well at all!

Whats the max safe mem voltages for Llano, is it still 1.65v?
