Ram in Karmic

[Belac Ile]

Is there a ram cap in Karmic 64? I was thinking of giving myself more ram.

Thanks.

Re: Ram in Karmic

The answer is "YES", but it is a number that far exceeds the capacity of your computer for installed RAM.

In the fine print, you'll find it is 16.8 million terabytes.

Thanks for the answer.. Sorry for the late reply.

Turns out DDR2 is now ridiculously expensive...

Why do you say that? DDR2 is as cheap as it has ever been, as far as I can tell. Here's an example (not sure what speed you need):

Looks like a good deal if PC28500 is fast enough.

I bought this last year at around 40 bucks.. maybe it was just really cheap then

also would it be ok to run 1066 ram with 800 ram? The aforementioned ram is being difficult to overclock.

would you also know anything about overclocking RAM.. I am most definately a noob

for example, what makes 4-4-4-12 better then 5-5-5-15?

Wow, I did not know you could ever get 4GB of memory for much under $100. Oh well -- that stuff changes like the weather.

Overclocking -- I know just barely enough to overclock my own motherboard, but beyond that I'm no guru. For the basic functionality, you need to know the front side bus speed spec for your motherboard, and then you need to buy memory that supports that speed as a minimum. For overclocking, you want to buy faster memory than the nominal FSB on the motherboard, because it's going to crank up higher than that.

I would not advise the "mix 'n match" approach, and for sure not two such vastly different speed ratings as you listed. One of them is not appropriate for your motherboard -- depends on the FSB rating, but either 1066 is too fast, or 800 is too slow.

For a non-overclocked computer, I have "cheated" a little and, for example, installed DDR2 1150 on a board that was spec'd for DDR2 1200, and it ran fine. But the risk was mine -- I would not have been entitled to a refund if it had crapped out on me.

As for mastering the intricacies of memory voltage control and the RAS tweaking, I have not needed or wanted to go to that level. On my Intel board, all I had to do was increase the clock multiplier from 10x to 11x and I got my 10% overclock (actually more than that), and I called it "good enough". There are forums where you can learn about that stuff -- here's a pretty good one:

Re: Ram in Karmic

this helped a lot.. now my CPU RAM and Video Card are over clocked... thank you

Caution, hardware geek answers follow...

Yes, you can run 1066 mhz memory in the same machine as 800mhz RAM but all memory in the machine will run at the slower speed.

And on the 4-4-4-12 vs 5-5-5-15 thing, here's a pretty fair readme on CAS latency and what it means -
