Stuck at 3.8GHz OC with the 965 C3 [4GHz OC now achieved] - Page 5

WOWOWOWOWOWOWOWOWOWOWOWOWOOOOOOOOOOOOOOOOOOOOOOOOO OOOOOOOOOOOOOOOOOOOOOOOOOOOWWWWWWWWWWWWWWWWWWWWWWW WWWWWWWWWWWWWWWWWWWWWWWWWWWWWW

I can't believe what I'm seeing. I'm currently at my known stable 3.75GHz OC with a 250 bus speed running Prime95, and I can't believe what I'm seeing - I can't say that enough either. Right now my CPU is at a temperature of 49 DEGREES CELSIUS!!!!!!!!!!!!!!! And that's while running Prime95, typing this, and uploading pics of my heatsink from my phone!!!!!!!!!!!!!!!!! My average temp earlier today was 62 degrees!!!!!!!!!!!!!!!!!!!!!!!!! It's down (pulling out calculator) 13 DEGREES!!!!!!!!!!!!!!!!!!! AMAZING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I am so glad I made my self walk to Wal-Mart, then to Home Depot, then run across the highway twice while crazy NASCAR fans were all honking at each other and putting the "petal to the metal" like speed demons just to get to Autozone and get the holy grail of sand papers I was looking for (took me an entire hour to do all that as well)!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!



Anyway, as you now know , I ended up lapping my heatsink to remove the black stuff on it. In case you're wondering I used grits 320, 400, 600, 800, 1000, 1500, 2000, and 2500. This took me like 4 hours (I know it's 2 for most people, but I'm slow so it takes twice as long lol) to do and I got the black marks off at the very beginning of it all, and now I have a mirror reflection on my heatsink. Here are the before and after pictures (taken from my phone):










Man, I still cannot believe this - the Arctic Silver 5 still has a break-in period too, so my temps might lower even more!!!!!!!! I'm so happy right now lol. This is insane, I had no idea lapping my CPU would make this big a difference. Just had no idea. Man, now I can't wait to try a 4GHz OC, haha heck I might even try for it now since I'm so pumped I can't fall asleep. Or I can just play some BBC2 and get frustrated out of my mind, I don't know yet, but I'll think on it.

I'm also stuck with 3,8GHz because of vdroop on my board. I run 3800 with 1.4750V and on load it is 1.42-1.45V.. I need over 1.55V to keep 4GHz stable I think. Not nice to run it 247 But happy on the 3,8 result

Call it what you will but I would never have tried to only use FSB to OC on a PHII BE. That's what my chip likes and my EVO board pointed that out to me.
If you prefer to just tell people your better to give up than try other options so be it.

I prefer to point out all the options avaible before seeing people settle with less than they desire. Not every person is a computer pro and can figure everything out on their own, hence the reason for posting on this board.

Congrats man. Thats good. With a lil room in the temp area you may be able to bring that chip higher if you want. You may hit 4 gigz yet.

I would go to 4GHz but motherboard's vdroop is nasty.. I don't want to go idle 1.60V 24/7 to get 1.53-55V on load to juice up the 4GHz. Anyone else having some vdroop?

It helps in vdroop and the fluctuation of vcore
I just put it on 0% for maximum stability when overclocking.
(IIRC, the lower the % less vdroop)

Double Post:


I'm currently Prime95'ing a 4GHz overclock; all my specs are the same as my first post:

Bus Speed: 200
CPU Multi: x20
VCore: 1.5v

NB Freq: 2400MHz
CPU/NB Voltage: 1.15v
Chipset Voltage: 1.1v

HT Link: 2000MHz
HT Voltage: 1.2v

RAM Freq: 1600MHz
RAM Timings: 9-9-9-24
RAM Voltage: 1.5v
DC Mode: Unganged

At this point, 4GHz doesn't seem like the highest this can go, I'm going to restart my PC and push this thing to it's limits!!!!!

Oh btw, the max temp so far has been 58 degrees, so actually, I think it's close to it's limits haha, but I'm going to push it nonetheless.

Good job.
post #50 of 82
You are at 4 GHz and 58c.Don't worry about going farther than that.You need to get your RAM optimized along with the IMC now.That RAM will take 1.7v easy-and you should be able to run 1800 CL8 or 1600 CL7.Get your NB running around 2700.If you can get these stable with a 4.0GHz CPU-then you will notice your system fly.
