Improper OC = micro stuttering?

post #1 of 7
Thread Starter 
Hey there,
For a year I have been running my E8400 at 3.6Ghz with setting only the Vcore to a fixed (1.25v) and DIMM voltage at 2.1v. I did not know much about overclocking but I had it on auto and then I checked CPUz to see what the value was and then I started manually decreasing the voltage until I was running into problems.

Recently, I finally decided to push it to 4Ghz and set the voltages to their standard voltage values and went from there... Finally When I got it stable at (500x8 1.32v) I started a game(any game) to find out how smoothly it was running, I was in shock that all this time I have been playing with micro-stuttering. It was just sad.

I would like to know what exactly was the cause of this problem? I guess its something you only learn from experience.

Thanks!

Microstuttering is a phenomenon that arises from two GPUs having discrepancies with frame renderings...and to my knowledge isn't possible with a single GPU.

Well, yes I know its more discussed as a GPU issue, but you see with my old overclock games would feel jittery. As if I missed a few frames each second even tho my FPS is well over playable fps (+80fps). With the new overclock it feels as if I got myself a completely new computer that runs flawlessly. Note: I still get the same fps so it is not the extra 400mhz.

I am thinking its something to do with voltages of other components since those are the changes I have made. Since they aren't on AUTO now.

Its a desync thing where the FPS is the same but its no longer timed right. Data has to pass through quite a number of steps before it reaches your eyes. Each part is operating at its own frequency ... think about... oh... say... a bus network. you might need to take 3 busses from point A to B and the total combined bus travel time may be 45 min. Since all 3 routes are continually running you would think it would be a 45 min trip but you have to account for the times you are waiting at the bus stops for the transfer. If your bus gets to a stop 10 seconds after your next bus has just left, you are in for a LONG wait.

Wait, you saying its the extra 400mhz? I honestly think some component was choking on excess voltage or something. I just want to know which of the changes I made improved performance.

Voltage can do it too, there are a number of things that can cause this really, but even if each individual component is running properly, the wrong combo of frequencies can cause an occasional frame to drop from the "waiting for the bus" effect

Well in this case it seems more than occasional but you get my point.

This is actually the reason some nicer overclocking motherboards have offset and delay values.

That's good to know but I'm assuming mine doesn't have those offset and delay features, I will mess around with it more when I have time during the summer. Until then!
