Hey there, pretty much any overclocking question I look into I inevitably end up here, so hopefully you guys and gals expertise can put me at rest.

I recently bought a new computer and for a change I decided to put it together myself. I bought a overclocked bundle cpu/ram/mobo but after reading up about certain specs i'm worried about some of these overclocked settings.

Memory - 4GB (2x2GB) Corsair XMS3 DDR3 PC3-12800 (1600), Non-ECC Unbuffered, CAS 9-9-9-24, XMP, 1.65V.

Motherboard - Gigabyte GA-P67A-UD4, Intel P67 Express, S 1155, PCI-E 2.0 (x16), DDR3 2133, SATA 6gb/s, SATA RAID.

CPU - Intel Core i5 2500K Unlocked, Socket 1155, Sandy Bridge, Quad Core, 3.3GHz, 6MB Cache, 95W, Retail - overclocked to 4.7ghz.

What I read about voltages and cpu speeds and such it worries me that i'm running really close to "dangerous" levels. Below are some screenshots of the stats but I just want peace of mind. The reason why is because when i initially booted up the pc it restarted itself after failing to load the os ( first time boot - no os - forgot to put disc in) so when it started back up it came up with a warning that this was because of the overclocked press any key to continue. After this it booted fine everything is fine.

Once everything was installed i went to bios and saw there was a "profile" which i assume was the overclocked one so i selected that - this overclocked the memory. After this i saw the multiplier for the cpu was on x33 so i put that on x46 (advertised at 4.7 but i couldnt remember speed). These were the only changes i made.

I was nervous adjusting these as 1) wasn't sure what i was really doing and 2) would it void warranty? not sure how this works tbh if it comes overclocked.



In your professional opinion are these settings ok?

Thanks in advance,
Kyle.

p.s ive played a few games ran 3dmark and ive had no crashes no bsods and no more error booting up about overclocked settings.
 
Your memory should run at much lower voltage. Those often run down at 1.3v.
Before you go trying download Memtest 4.2b (i think is the one that works with sandy bridge) - put it on a CD and boot the machine to it. If you check its passes before you boot to your OS you will save corrupting the OS if its unstable.

With regards the CPU speed, your screen shot it shows 4.6GHz not 4.7GHz and its hard to advise without seeing temps under load. Can you run Prim95 or Intel Burn test to get all the cores running and then report the voltages and temperatures.
You also need to get a copy of CPUz 1.563 beta as 1.56 does not report sandy bridge voltage correctly.

Thank you I shall take your advice and post my results.
 
Perfect.

Well your CPU voltage looks ok to me. Its as high as i would go for day to day use but as I say looks fine.

Keep an eye on temps, you hit 69c while running the test and your not running it at it's strongest settings, but even so hitting 69-70c under sustained load is not a problem.

I would say you have nothing to be concerned about... Just see if you can get that RAM voltage down.

I really appriciate you taking the time to help me, thanks very much. I need to get some discs first before i can run the memtest, on a side note i notice that most sites to purchase this ram it does state 1.65 but overclockers says Sandybridge compatible (use sub 1.60v) - is it worth my just adjusting the voltages or should i definetly run memtest first?

It depends if you are prepared to risk your OS install?
You could just try stepping it down slowly and see what happens. Worst case it will cause a BSOD and corrupt your OS files but this does not always happen.

I know it says 1.65v on it, but OCUK tested it down to 1.3v and I had some and can confirm that 1.3v was fine... But every set is slightly different of course.
