Benchtesting New Computer

Anyone know the best way to measure maximum CPU core speeds? Right now I'm using prime95 torture test and CPU-Z to measure the speeds but I can only get it up to 3.9Ghz. If I use CPU Speed Pro it only reads as 3.3Ghz. It's supposed to be overclocked to 4.2Ghz and I want to make sure it is so.

CPUZ will tell you everything. Gpuz is also nice. Openhardware monitor is also a good one to run.


Derp, I am half alseep and realized I read your request wrong lol.

Are you overclocking through the motherboard software or bios? What motherboard? CPU z

[ictponder]

I'm not overclocking it, it should already be overclocked. I've checked bios and there are options for overclocking available but I'm not going to mess with it, I just want to find the max core speeds possible on this CPU (what is it actually overclocked to)

interesting i need someone to come overclock my stuff lol

More than likely they overclocked it and left all the intel speedstep stuff enabled which means your cpu multiplier is going to be changing based on load on the processor so you'll likely see it at like 1.something ghz while just idling in windows and when you put a good load on the cpu, it'll jump on up to wherever it's supposed to be (and a bunch of places in between)

LinX is a good test and can also help you understand when your cpu overclock may actually hinder performance (yes it does happen if you have a higher clock speed but it's slightly unstable, you'll see the measured GFlops after each pass which you can use to ascertain whether or not it's running properly)

Since you just want to see what the max core speed is, you really can just look in the bios to see what the effective clockrate is, though since I have no idea what cpu or motherboard you have, I can't tell you where to look. I personally use Aida64 for monitoring my pc, but CPUZ will tell you straight up what the cpu is overclocked to as well as the multi, bclk, etc

Right now it idles at 1.2. The highest I can get CPU-Z to read is a 39x ratio even though there are more options in bios, maxing it out at 3.9 (100% usage). I've tried changing the CPU ratio in bios but it doesn't seem to have any effect, almost like it's locked. I really like Asus' UEFI

CPU-Z indicates the board is made by Alienware, model 07JNH0 as is the bios. CPU is i7 3960X

Apparently this says it has a 4.2Ghz Turbo Boost option, which sounds kinda lame like a very short term thing but it's there.

Oh that turbo boost stuff generally is only applied to the first core or two, the rest will remain at the clock they're supposed to be at. It may be they only overclocked it to 3.9 due to heat or something. Is it using the stock intel cooler on the processor or does it have an aftermarket cooler on it?

I noticed in the bios that only the first core has a x42 ratio so that must be the only core that's overclocked like you said. It came with a liquid cooling system but I'm not familiar with what type it is. At full speed the CPU runs close to 42 degrees celcius.
