Benchtesting New Computer

[ictponder]

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)

[nodoze]

interesting i need someone to come overclock my stuff lol

[MaelstromOC]

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.

[MaelstromOC]

That's totally fine with the temperature there, definitely room to overclock a lot if you wanted if it's at 42 while going full bore. Also, all cores are overclocked to 3.9, just the first core gets the boost to 4.2ghz. That's a silly way of stating they'll overclock your cpu to 4.2ghz lol, but I guess it is alienware... hell they probably didn't even have to touch the voltages or anything to pump it from 3.3 to 3.9, that's nothing these days! Not when you see those same chips running 5ghz+ in people's pc's haha.

I imagine its probably one of those Corsair H50 / H70 zero maintenance water cooling setups. Which are decent if your not down for doing it yourself, but not nearly the cooling properties of an actual water cooling loop.

You should run OCCT for burnin and Benchmarking. It has a really nice UI and a decent suite of tests.

[DocWalt]

OCCT is definitely the way to go for burnin and benchmarking. Plus it reports the CPU clock speed as it loads it up so you can see it run through the different speed steps.

[FeaRpb]

OCCT worked amazing for me and my burnin/overclock testing.

[a2j]

prime95 can tell you how stable your overclocked cpu

[Zaroth]

So does OCCT. If it runs through the basic test (100% cpu usage for 1hr) it's stable. :) If you want to test the stability of more specific hardware or circumstances you edit the parameters and run it again.

Will have to check it out.

[FeaRpb]

I recommend it.

[DocWalt]

I'd reccomend running OCCT for a 24 hr period on initial burnin or when you overclock and decide on a new OC speed. That way you know for sure you're going to be 100% ok. I have had errors come up after 16 hours of testing at 100% load.

[FeaRpb]

I have always wondered this Doc, but I am pretty sure that girl in your avatar isn't wearing any underwear and her vag is showing.

hmm, idk, only had the avatar sized pic and never gave it much thought. Changed it to be on the safe side :)

PassMark - CPU Benchmarks - List of Benchmarked CPUs (http://www.cpubenchmark.net/cpu_list.php)

my cpu passmark on my quad (quad core opterons) was 11,000 total cost 100$ in cpu, plus 200$ for the motherboard, 100 $ case, 150 power supply, 300 in memory.

upgraded to opteron 8384 for another 100$ it scored almost 13000 in cpu passmark.

yep, 24 hours without errors is something I'd consider stable.
