PPO,the XMP profile for my memory is 2000 9-10-9-27-2T. Of course Sandy Bridge doesn't support 2000MHz. Anyway, 2T is standard for most memory to my understanding. Regarding memory tests, passing most of the time is indicative of some sort of problem. You need it to pass all the time. What voltage are you feeding to your memory? And can you give me a link to the set of memory you're trying to OC?

Memory is at stock 1.5v.Here's a link to my memory:My link

Link didn't work, but you're probably going to have to give it a little more voltage to overclock it. My memory will do 1866 9-10-9-27 1T at 1.54v all day long, but 2133 9-11-10-28 1T requires 1.65v. I should mention that some people don't think 1.65v is a good idea with Sandy Bridge. It's certainly not going to hurt anything to try 1.55 or 1.60, though.Disclaimer: this is with regards to memory voltage, not cpu voltage!

Hi GuysNew on this forum, just had a basic question to ask. I am getting an overclocked bundle this week and wanted to know what a 'safe' CPU voltage was? It will be clocked to 4.6GHZ so would 1.4v be in the right ball-park?CheersS

For 4.6, you should only need about 1.30v. Maximum safe voltage is up to you, but personally, I prefer to keep it under 1.4v. I'm running 4.8GHz at 1.4 exactly. Welcome to the forum!

1.3v max for 4.6 GHz? I get arround 1.35v with an Offset of -0.020.

Well, 1.30 may be a little low for lots of chips, but to clarify I didn't say max, but rather about as in 1.30v approximately.

I'm brand new at this, getting a new system delivered Thursday, but you guys seem to be the experts. So my question is, where do I start in order to end up where you guys did.. My system will featur a Z68 MOBO. Need guidance. Thanks. Dan

I've notice that some of you have speedstep enabled and some don't. In my experience I think I got fewer stutters with speedstep disabled but am reluctant to leave it that way. (Had a chip fail but was replaced under warranty...2600k)

Hi Can we start directly from a set of settings posted here and see if it has good resultes or should we begin the overclocking with 4,5GHz and then 4,8 and then 4,9 and so on? Do I need to test first 4,5GHz to be aware that the processor can handle it? harpsi

I'm not familiar with all the motherboard brands, so I'll only speak for ASUS. If you're using an ASUS board, a good approach might be to copy someones settings for 4.8GHz, but set the frequency to 4.5GHz and perhaps add 0.01v to the offset voltage they're using. See what load voltage you get and go from there to try to increase frequency and decrease voltage until you can't anymore. Offset voltage is completely dependent on LLC, though. Don't try to copy someone's offset voltage with a different LLC setting. For stability testing, run prime95 blend. Make sure you have CPU-Z and realtemp installed before you even begin prime95. Voltage increases with CPU load, so it's especially important to watch the voltage in CPU-Z while prime95 is running. I would recommend staying at or under 1.40v at all times. You really don't want your maximum core temp to exceed 75C to 80C.

I keep that in mind but after buying the computer, which will happen probably in 10 days, I will be back to this question from the beginning even after reading a lot of tutorials, like I did in the past days... But theorics is one thing, pratics in another thing. So, I must do it in my machine and not just read and read. :) harpsi

Great idea Stephen! My 4.8 w/1850 BIOS (improves stability). This setup has not failed me and stable with Prime95 and ASUS Stress Tests. Very stable with FSX too and no CTD's and I get great FPS (above 20 most of the time but never in the single digits and very smooth)(FPS locked at 34) in FSX w/ASE, FEX, several commercial aircraft addons, MyTrafficX, MegaScenery running. I also have FTX/Orbx scenery too when FEX is not running.Best regards,Jim

Does anyone know why my pictures disappeared? They were within the guidelines of the AVSIM picture policy. Not a major thing as I have subsequently changed most of the settings I posted. It was my first major endeavor to post pictures on AVSIM and I thought I had done a good job. I would just like to know in case I want to post additional pictures of my BIOS. Thanks.Best regards,JimEDIT: Is it because I didn't post a picture of my dog? LOL. (Don't have one but I could have found one....)

Hey Jim! What? No dog? Then you don't have a best friend, poor man! Have a third party host the pictures and use the URL for each picture. In front of each picture this URL code must appear [ i m g ] and afterward [ / i m g ]. Make sure there are no spaces. A good free hoster is: http://www.fsfiles.org/flightsimshots/Hope that helps!Kind regards,

Hi Stephen,Thanks for the info. I kind of thought that would be the case but wanted to make sure. Love the picture of the your dog as well as the one you posted on the previous page. Thanks for the excellent link to the free host website!Best regards,Jim
