TPU's Core i7 Overclocking and Feedback

Do you have LLC on Johnny? Also, how do you have your 4870x2 cores so cold?

Anyway, here you go. Bios is 1.4 vcore after vdroop is 1.32 according to cpu-z. Max temps were 84 but heater kicked on when I started. It dropped 2C after it turned off.

I have my 4870X2 fan at 45% mastr, always had it around 45% to keep it at reasonable temps. LLC is ON. I'm topping out at 76C, ambient was 23c. Your ambient you said was 24-25c? Seens spot on. Intel Burn Test is pretty... intense.
 
Now that I have the watercooling in I'm trying to push mine some more. I have the CPU at 4.4GHz, and I was able to run most of the Intel Burn tests (did not run the highest though). I tried to run Prime95 last night and it bombed on me somewhere, but I didn't even get any bluescreen "Serious Error" messages this morning when I logged back in.

Otherwise, the speed seems rather stable.
 
Looks like minor instability. Something might just need a slight bump in voltage and that's it :)
 
Too bad I could not get a BSD error # so I could easily identify it. :mad:
 
Want to list your voltages and have us take a look at it?

Oh, 45% eh? You got the case around the corner in another room? :laugh:

I think I would see high 80s with you voltage and LLC on. I tried 1.35v with the 21x multi but it was throttling pretty bad and I had just started LinX.

Perhaps I will, but the ol' lady is mad at me for all the time I've been spending in the basement :banghead: Finished putting the i7 rig back in the case with the WC loop, parted out & cleaned up my old second rig, and started putting the new second rig (HTPC) together. Last night she went to bed before 7:30 pm without so much as a word :(
 
Go do what you gotta do man, we ain't going no where. :toast:

Can't really hear the vid card over all the case fans, its noticeable, but not annoyingly loud.
I haven't gotten anywhere near 80c with my current setup. My 920 is lapped though. :D
 
Disgusting I know, but I haven't tightened them up at all. I just left them on SPD to see how high I could get the CPU. Kinda surprised I am up to 4.4GHz with HT on and relatively stable. I guess I finally found a decent combo between this CPU and the Classified.
 
Dropping the mem divider might help with a higher overclock. Everything else seems about right.
 
Anyone here? Hellooo?
 
yeah for 3 months lol.
 
well after playing with my xeon for a week i seem to be having a problem with it or something in my machine.

i keep getting errors on the 2nd core during benching and encoding video.

this only happens when the cpu is OCed to 4ghz or higher though.

i've tried more and less voltage in the normal areas of need but still have the same problem.

the only other thing i can think of is my 7 install has gone bad.

any input?
 
I just sold my i7 rig (see system sepcs) for 900 euro's (1300USD$)

aw!

it was nice to have it but I didn't use all it's power ,so I sold it now it still has any value.
Maybe I'll buy a new system next year with a 32nm CPU!

good luck with your i7's guys

Thanks bro :toast: Your sig cracks me up :laugh:
 
I haven't read through this thread(coz it is so long now), but is the information contained within referring/applicable to socket 1366 i7's only?

My E8500's 2nd core use to always crash even in SP :shadedshu

It was just a weak core, I tested it on different motherboards/OS/RAM same thing always happened.
 
Just last week I tested two 3939B chips, one was nothing special, and the other one resulted in a .9Vcore for 4.0GHz

exact batch # on the .9Vcore ? I know it doesn't matter, but i have a 3939b002 and don't have it set up yet, would like a ballpark on what to expect
