Overclocking my i7-950 further...

post #1 of 8
Thread Starter 
Been a while since I posted anything here... After all the gpu and cpu temperature problems got fixed a couple of months ago, I finally got the courage to OC my cpu.

I easily got it to 3.36Ghz but after that the, what I call, "messing around" started. It seemed to be problem with my RAM so after that I got my RAM stable (I ran 12 hours of Prime95 blend tests), I got my cpu to 3.5 Ghz (Ran 6 hours of Prime95 Small FFTs). But now I just cant get it higher or atleast not sure how to get it higher, as I'm a bit afraid to increase the voltages more.

I can get windows to boot but once I run prime it instantly BSOD's saying that the cpu missed a clock cycle (or something... Id retry to BSOD it to get you guys the specific error stuff but I'm kinda hesitant to BSOD it again deliberately).

http://valid.canardpc.com/show_oc.php?id=2138461

If anyone could me give me some more specifics on what to change, I'd be really thankfull! And how far can I safely push the Vcore and Ram voltage?

You could EASILY add another tenth of a volt to that.

I wouldn't take the memory over 1.65v or the Vcore over 1.35 if your nervous.

The i7-900 series cpu's are listed for an absolute max voltage of 1.5v per Intel Product Data Sheets, so you dont need to feel nervous. I do understand tho, it took me a while of tinkering and such before I started feeling comfortable.

 

I run 1.40v 24/7 without issues.

 

 

However being I dont see anything listed in your specs for cooling I dont know what to suggest for you. These cpu's run a bit warm, and if you dont have a good after market cooler your not going to want to mess with it.

 

 

Check the link in my sig below for the 950 thread, plenty of folks there that can assist you in getting a good 4.0 stable OC thats safe...

Don't be afraid to increase your vcore, you still have a huge margin to mess around with.

No clue why my cooling wasnt in there tongue.gif got a cooler master V10 on my cpu.

Thanks guys, now I feel a lot safer biggrin.gif

edit: when I'm running Prime and I see the multiplier changing all the time, is that a bad thing?

It means you have some form of speed stepping enabled. That can be OK up to 4.2GHz, but I normally disable it for overclocking. (EIST, C1E, and other C- states) Just my preference.

Overclocking my i7-950/X58A-UD3R Settings Spreadsheet

Anything over 1.45v (after vcore drop/droop) probably isn't a great idea 24/7... but I have this problem with accepting boundaries..wink.gif

Thanks! Im quite sure I had those all disabled... VDroop, the c thingy and EIST... Ill have a look at it tomorrow, got classes in the morning so Ill first be getting some sleep!

Btw I only had the multiplier changing when going beyond 3.5, or is that normal if one of the speedsteps is enabled?

I think so, but bring yourself over to the 950 club in my sig to get a broader response. It'll give the guys something to chew on..thumb.gif
