Right voltage

[stolenhonor]

I bought 2gb of DDR2800 ram sticks. But under pcwizard it says there running at 399mhz, shouldn't they be running at 800mhz?

DDR = "Double Data Rate"
Double 400 = 800
Therefore your chips are running at the proper speed

ohhh, I didn't know that. thanks for the info.

Also What does upping the voltage do?

 

[Scotteq]

The general idea is to only use the amount of voltage needed to run stably. People who overclock (run faster then the rated speed) often need to increase the voltage in order to make their components run at whatever speed the person set (instructed to Bios). But that's only because they're making the thing work harder than it's supposed to.

Less volts = less heat, which contributes to longer life.

@OP: Check your RAM divider.

In my bios it says voltage. +0.2,+0.1, and it stops at +0.3v and its highlighted in red. Im not sure how to do it. On my ram box it says 1.8~2.0V. I dont get why my bios says +0.3 and etc.

If you select +0.3v it will add that to whatever the defualt voltage is and running at. Like if its running at 1.8v stock and you select +0.3v it will now be running 2.1v. It should say in the bios what the default ram voltage your mobo is running it at.

Correct. The default memory voltage is 1.8v.
Your memory should be set at 1.8-2.0, therefore +0 or 0.1 or +0.2.
You can test your memory and cpu for errors with Prime95.
Whatever voltage works for you without errors is best.

Well I have a new chip with an unlocked multiplier. I will haft to experiment with this, trial and error I guess.

For specifically testing memory I would also recommend memtest86 v1.70. From what I have read memtest will be alot more accurate than using Prime95 or Orthos regarding memmory errors.

What one to run first I have no idea, I'm still learning to OC myself. I would recommend memtest asap with a new build or new ram to make sure it has no errors before you get started. What I have been doing is every time I change a setting I then run Orthos for 10 mins or so and if no errors i will keep going. When I get to where I am happy and I get everything stable thru an hour of Orthos then 2 passes thru memtest. If both those pass without errors then thats when I do a 12 hour Orthos test.

With memtest you will need to make a bootable floppy or a CD image if your dont have a floppy drive. Either way its worth it to get memtest.

When you say errors? That means something not right with you upping the voltage right?

Ya, if there is a flaw in an OC causing problems you will generally see errors in orthos or memtest. It's hard to say what you should be running your memory voltage at without know what mobo your sticks are in and if you plan to OC your cpu or ram. If your not OCing and your comp is running fine atm I dont think its nessesary to up the volts. The options in your bios to increase the voltage is for stabilizing an OC because when you make stuff go faster it needs more juice.

I have a qustion about the video stress test in counterstrike, I get 59fps, why? My friend has a AMD Athlon X2 3800 with the same video card and gets a little over 100 fps. My Ram runs at a higher mhz than his and im all sata and he is not. As he is 939 also and im AM2

Quick question, what app did you use that created that screen shot? I am just discovering OC, and I need some utilities first. Thank you...
