CPU and RAM sync

post #1 of 10
Thread Starter 
Hello !

I'm going to buy Phenom X4 965 CPU, I will be overclocking it to 3.8 ghz, however I have read that for overclocked system to be stable on of the essential components are CPU and RAM sync. I haven't yet decided which ram to buy so, can someone please explain me what that means ?

Thank you.

I think what you have heard about is this
when ocing the cpu with fsb, the ram speed also increases. If your ram isnt capable to handle that load, then the OC wont be stable. The solution is to get a memory whitch can handle a lil bit of OC on its own.
Since you are gonna buy a 965 black edition cpu, you dont need to worry about this too much because you will have the support of unlocked multipliers. I suggest an FSB of 218 and multiplier of 17.5 for you.
As for memory modules, try to get some thing with low cas latencies. corsair XMS3/GSkill Ripjaws 1600MHz rams with cas latencies 7-8-7 would be great for you. While OCing, try to raise the cpu-nb speed too, that way you will get more performance out of your ram.

Thank You for very useful and enlightening answer. I think I have decided on RAM and mother board. However I would really like to hear your thoughts-

Thank you.

The chipset you have selected (890FX) is the best one available for amd systems. Since biostar mobos are not sold here at my place, I really cant comment on its build quality. Personally, I have found ASUS and Gigabyte to be the best board makers in that order. If you know for a fact that the biostar board is reliable, then go for it. If not, then go with asus. One more thing, if you are not going to use crossfirex (two graphics cards) then you can get a board with some lesser chipset like 890gx or 880g. That will save you some money.

........these are three links to three set of memory modules i have selected for you. you can go with any one of these. I personally own a pair of xms3 and i have used gskill(first link) in many pcs. You can safely pick any one of these. try to find good deals for the one you select.
No matter which one you get, after installation you will have to go to bios and set up the timings manually. its pretty easy standard procedure, we can discuss that later.

Thank You for broad explanation. However, all RAM's that You have selected are DDR3 1600, however the motherboard only supports DDR3 1600(OC) /1333/1066/800. Will the RAM be compatible with the motherboard ?

Yep, it will.

Those Crucial Ballistix sticks are much cheaper at Tiger Direct right now. $60 for 4 Gig of DDR3 1600.

I have one more question regardin RAM, lets say that I buy a 2x 2GB RAM, but later I want to update to 8gb total. If I don't have possibility to buy the exact same RAM as I'm using now, what should I be looking for choosing the different manufactor RAM ? How it will behave if I have 2 stick of 2gb RAM of one manufactor and 2 stick of 2gb RAM from another one, given that all the stats are equall ?

Thanks

If the spd values are equal, then they should work together. still it is recommended to use memory modules from same manufacturer.
Lastly, to ensure your peace of mind I must add, the corsair XMS3 and GSkill ripjaws are here to stay and they will stay in the market for quite some time.

Can't really go wrong with some high quality Corsair and that said, G.Skill (made of pure win), I like meh MSI mobo, never the first days trouble but different strokes for different folks.

Like it was said, where the "match system to ram" topic comes up is when you want to OC using the front side bus, personally thats the preferred method, so to accomplish this a good "proven" mobo that has shown capability to reach a high fsb is a good way to go. The 965 "be" like all black edition chips are core unlocked, so getting a higher frequency is as simple as changing a multiplier.

One tends to see better performance though with a higher fsb and a lower multiplier. The difference in good ram and not so good ram is that flexibility to try more options and different speeds minus trips to the cmos clear jumper.
