Besides speed what is the difference between 800 and 1066?

post #1 of 32
Thread Starter 
Are 1066 better overclockers or could they handle higher fsbs? I'm trying to get my e6750 higher but I know my ram is holding me back fsb is at 450 right now. What should I get 800 or 1066?

Well that's quite like asking "Beside speed, what's the difference between two speeds?" Basically the front side bus that goes from your core clock also controls the speed of your memory. Here's where memory dividers come into play. You can control the ratio of your core clock to your ram speed with memory dividers to get the most performance. Of course, on OCN higher speeds = better!

Excuse me if I'm using the wrong terms to explain things. This is the gist of overclocking as far as ram is concerned.

Well I lie. There's also ram timings and multiple voltages... but let's not worry about those for now

Yeah, crashnburn is right, keeping it simple is probably a good idea until you learn some more. What speed is your ram rated at right now?
post #4 of 32
1066MHz ram is overclocked 800MHz ram that's binned higher because it can take the clocks.



Edit:If your tring for higher clocks you should pull 2 sticks or ditch the 4*1 setup and go 2*2.The more dimms you fill the harder it is on the NB and it limits your oc.

Typically, good 800mhz ram runs timings of 4-4-4-12 with 1.8v or so. 1066 will run 5-5-5-15 at 2.1v. These are just median numbers and you will find a wide variety of memory.

Well if they are bined higher than means I would have the ability have the fsb high while lowering the also have the ram timing high right? My G.skills can't clock over 900. Anything over it goes unstable even at looser timing. My current ram are rated at 800 and I'm currently going about 901 with nb strapped at 333mhz?

I just wondering if upgrading to 2 sticks as well as faster speed would allow higher fsb overclocking. But I didn't know if the rams default to 1066 and the ram speed increases from that or I can have a lower clocked ram that is rated from 1066 and start from there.

My mobo doesn't have good ram overclocking options unlike my old p35 gigabyte so my ram tampering abilities are very limited.

Low timings = good!
Also, as long as you have memory dividers that run your memory stable, there should be no problem. Check the voltage on your G.Skill's. Too much can fry them.

Anytime you go with higher clocked ram your going to increase your oc option because you will not be limited by your ram and yes a 2*2 kit is better for overclocking incase you missed my edit in my first post.

My mobo aways set it to 1:1 so I can't settle for a slow option. I also have timings at 6-6-6-18 in order to increase fsb. My ram can go up to 2.1v but I have them there and it still can't get a mhz over 900.

And sasquatch yea I got that. I am going for a 2x2 option.

Well I guess I'll be getting some new ram. Now to decide OCZ reapers or G.Skill PIs or once I figure out why people get corsair dominators I might consider those also.

rep for the help peeps =]

Go with the G.Skill PI(though G.Skill tends to bin pretty tight and you more or less get what you pay for) or you mite want to consider Muskin XPs.Muskin has really bin kick'n it here lately and everone that ownes these swears by them.
