Slower after OC?

Hello, I recently over clocked my Intel i7 from 3.06 to 3.43 and it seems to have slowed my computer down? Can I get some clarification on this if maybe my voltage would slow down the computer? I'm very new to over clocking so that's why I'm having this issue... Running stress tests with Intel Extreme Tunning Utility.

More about : slower

You can just run some empirical tests. Intel Burn Test will give a result in GFlops of computing power, or 3D Mark Vantage has a CPU score.

Also... did you disable EIST/Speed Step, Turbo, C States or anything like that?

I disabled Speed Step and Turbo, also is it normal at be running at 42C idle? BIOS was sitting at 42C for the processor

That's probably why it's slower then. Most stuff isn't going to be multithreaded, so turbo will greatly increase speeds.

BIOS idle tends to read high, I don't know why. Mine's close to the same, in Windows it drops to around 39C on my hottest core.

Hmm, well then what's a good program to check core temps?

So I should turn on Turbo? I'm just not sure if I like the fact of my CPU hitting 3.73Ghz with stock fan.

Just passed stress test 15mins so that's good (first OC on this PC)

Stock fan eh? Yeah hard to say, temps will decide I guess.

I like RealTemp and HWMonitor to keep an eye on everything front temps to voltages and fan speeds. There's others too like Core Temp and Speed Fan.

Yeh... I am upgrading fan soon enough. Fan before speakers atleast hahaha... And thermal paste for sure.

Most heat sinks come with a decent paste, but you could always get the baseline "good" one, Arctic Silver 5. I've heard there's 3 or 4 better TIMs out there now than AS5, but it's still a good one.

Good luck.

I am assuming that you are using a 950 ?

I'd suggest you use the stock BIOS settings and do the following:

W/ DDR3-1600 Memory , do a 20% OC
160 BCLK x 23 CPU multiplier = 3.7 Ghz
160 BCLK x 10 Memory multiplier = 1600 Mhz

The only change necessary for this is to set the BCLK at 160 and DDR3 speed at 1600 [Memory Multiplier at 10, leave everything else on Auto. Make sure RAM timings are at "what it says on the package". If that runs stable I would drop the CPU and DRAM voltages in accordance with procedures described here:

If ya wanna go higher, the above article will get you there.

I would suggest investing in an aftermarket cooler.
