just started overclocking

[nitenichiryu1]

i have a 90nm 3500+ with msi neo2. my ram is ocz platinum rev2, rated at 2-2-2-5...did i do something wrong..?

your ram speed is the number shown with the letters DDR upon bootup. your default cpu speed would be the actual GHz speed of your cpu. I did a quick google search for 3500+ chips and it says 2.2GHz. your current cpu speed is 2.565GHz (=270*9.5). I'd say that you have a VERY nice overclock. I am concerned that you may not have set up your memory for a good speed. let us know what your memory speed is.

oh, hehe, thanks. i'll be sure to post that in the morning. i plan to go through the rest of the night in prime. hopefully it'll still be running by that time=P

Don't use 9.5 as your multiplier. Either stick with 10 or drop it to 9. Also, bump the memory voltage to 2.8 and set your timings tighter. Something like 2.5-3-3-10 at 1T. AMD machines like to use a higher TRAS number so set it to 10, maybe 11. You can probably hit 275 FSB if you set your CPU voltage to 1.6v. How are your temps?

 

[nitenichiryu1]

my temps are at 51 load and about 38ish idle. and yea, i wasnt sure bout my timings, because everyones kinda telling me that its a little too loose.

 

[JohnAn2112]

Well, 2.5-4-4-10 1T should be about right for 275 FSB, but if you're staying at around 270, you'd probably be able to pull off 2.5-3-3-10 1T. Give it a shot. Let us know how you do.

whew. last night i tweaked some more. i didnt loosen my timings because i decided to drop from 9.5 to 9 and fsb up to 280. so i was able to run prime with no error with 9x280 with 2.5-4-4-10-1t timings. is that still too loose? should i tighten up again?

 

[nitenichiryu1]

im back fairly quickly because my comp had an error running 9x285 and 9x290, but i was able to run prime for about 8 hours with 9x280. my ram timings are still 2.5-4-4-10-1t. is that ok for my current setup? i noticed i ran stable on 9.5x270. which is better? 9.5x270 or 9x280. thanks

LOL, you just hit was is known as the 1.3 HTT bug. I personally use 1.36beta bios. It fixes it and allows a large range of voltages at the same time.

Sounds like you need to find a middle ground there. Maybe try 9x275 to see if you're stable. If you are, then you got yourself a nice overclock there!

hehe thanks. i think im gonna keep the 9x280 with 2.5-4-4-10-1t timings. with as5 and zalman 7000balcu my temps never went above 53 at the highest. i keep thinking im able to do just a little more, because i didnt crank up the voltage on my ram or on my vcore. but i guess this will do for now until i learn a few more things. this was my first overclock and it was pretty fulfilling. thanks for your help, guys.
