Memory timing help

post #1 of 11
Thread Starter 
I have some cheap crucial DDR2 533MHz stock setting at 1-1-1-16 and I was wondering if there is anyway to get better performance out of them.

Errr. huh?

Filing in the category nonsense for now... no RAM that I know has those stock timings.

Link to the actual RAM please?

I thought thats what i was looking at, but I dont have the computer with me and mwave.com doesnt show the CAS so ill have to take a closer look at it when I get to it.

Ok, that looks better. ... LOL

Well, Intel systems don't care about timings too much; they more care about bandwidth. I would see how fast I can get that RAM to run in your system. What is the best overclock you got out of that RAM so far?

i think its at 560 right now, I dont want too push it too far because I depend on it a good bit. Can it fry if I push it farther?

It should not fry without warning. 560 out of DDR2 533 RAM is a mild overclock. Generally when you push it too far, the system will fail to boot, but no permanent damage is done (you'll have to reset your BIOS most likely though)

im just using the motherboards stock 20% OC setting, I want to do it manually to try and get 4.0GHz if it doesnt get too hot. What is the max you think I should go to?

Well. I think 4.0 GHz will push the RAM too far. For 4.0GHz, you'll need an FSB of 267MHz (multi = 15). If you leave it at DDR2 533, your effective RAM speed will be 267/200*533 = 712, which exceeds DDR2 667 speeds!

Knock the RAM back to 400. Then the effective speed will be 267/200*400 = 533, and your RAM will run at stock with your CPU at 4.0GHz (if your CPU makes it).

Too bad you don't have DDR2 667... that likely would have run at the 712MHz above.

As always, keep a close eye on CPU temps. Don't be too concerned about RAM temps... When did you get this RAM, recently or a while ago ? (aka, can you still RMA it for DDR2 667?)

I got it in january through mwave.com and its their house brand but its really crucial. Im probably going to get some 800MHz memory in a few months but I will check with mwave and see what they can do for me! I really thank you for your help and I regret not getting the 667Mhz memory like my original intentions were.
