well with these settings I get 74c MAX prime95/OCCT small ftts stable. thing is i keep getting random BSOD when just surfing the web, I can game ALL day/night, but i will blue screen randomly when not doing much, Please help if you could
-Thanks

Hehe im glad to here that but, i want to keep this beasty cool, would going up to lets say 3.8- 4 GHz have any effect of cpu life? haha my pc makes my room hot bad mostly b/c of the GFX card pumping out more hot air then a hairdryer lolz...



EDIT: BTW I learned ALOT from reading you're i7 Guide.

Go for 4GHz! I have basically the same core system, got 4GHz on 1.23Vcore, you might be able to get it slightly lower though. Not that it matters, but it will bring your RAM up to a nice pretty 1600.

I wouldn't be worried about shortening the life, as long as you keep the temperatures in check.

ok im testing 3.8/4 GHz atm

Yea, Xigmatek DK, im currently at 3.8 GHZ with 1.18 Vcore (running OCCT as i type this) but trying to boot up 4GHz wont take anything below 1.25 and that BSOD while running prime 95 within 10 minutes. Temps get up to the low 70's with 4 GHz. 3.8 on the otherhand almost matches the temps from the 3.66 GHz oc i had before 65c Max, so I believe i'll stick with 3.8 atm.

my case is actually quite large. but I am having this weird buzzing noise coming from the fan on side panel, i think it is like turbulence or something to deal with the poor design of the metal vent on the side b/c the fan is quiet while off but noisy while on. maybe its how close the fans is to the side of panel idk...

So I had it 11 hrs prime 95 stable/4 hrs OCCT stable yesterday and played games all day lol and no BSOD then when i stopped to go surf on the web bam lol... so i bumped the Vcore up to 1.19 and did a 8 Hr OCCT small data set test and passed, same temps as before So are there any bios settings i should change like load line, cpu pll voltage, or any of those settings i have on auto?

Bump

SOME1 help him...... i would, but i'm kinda n00b when it comes to the settings of OCing...

Mmk, but why do you have Intel VT Tech, Execute Disabled Bit, Intel C-State Tech dissabled? ATM im back at my previous 3.66 GHz setting b/c i kept getting blue screens and i know it wasnt the cpu voltage, maybe the QPI/DRAM voltage is what was blue screening me and that annoying duck sound that the comp makes before bs. those are some very nice temps you have there, what cpu paste/HSF do you use?


settings im trying to get stable:

AI Overclocker Tuner: [Manual]
CPU Ratio: [20]
Speed-step: [disabled]
BLCK Frequency: [190]
PCIE Frequency: [100]
DRAM Frequency: [DDR3-1467 MHz] [not sure i think 1500 something]
UCLK Frequency: [Auto]-does that need to be on auto?
QPI Link Data Rate: [Auto] -same ? ^

DRAM Settings:
7-7-7-24

Voltages:
Vcore [1.175]for 3.66 or 1.20 for 3.8
CPU PLL Voltage: [Auto] or [1.82]--best to leave this at AUTO?
QPI/DRAM Core Voltage: [1.25] --changed this 2 [1.20]
DRAM Bus: [1.64]

the ones i highlighted are the settings i most need help with, i know every chip is different blahblahblah...but it would be helpful if i could be pointed in the right direction

That's uncore (UCLK) - QPI is separate. I try to keep mine around 7-7.2GT/s - I find that's about that fastest I can go without any extra heat, voltage, or instability. Arguably, you could get some additional gain by upping the uncore a bit as well, since that would speed up the L3 cache, but I haven't tried it on mine (I just keep mine at 3200MHz, since my RAM is at 1600).

I have QPI at [3237] closest to 1600 or to actual running speed 1523 MHz [3046] Uncore at 6857 MT/s other choices were 8380, and 9143


vcore 1.20 QPI/DRAM 1.23 its supposedly the "golden rule" to keep QPI/DRAM voltages 0.3 the same as vcore.

Ima do a 2 hr OCCT test, (olny 2hrs b/c my comp makes my room very hot) and let you guys know how i goes after i sleep a little lol..

Ill talk to ya later, you brick bustin, thirst quenching, big glass full of red kool-aid man lol..

I may try upping my QPI/uncore in a bit - see if it helps on any benchmarks or anything. It could be an interesting experiment.

also i may add that my ambient room temps are quite high as i don't have ac in my room its just a ceiling fan, and how seeing that this is the summer and all, maybe i could wait until this winter and go for higher clock speeds.

Man....you need some better cooling!

Get a DICE pot or make one yourself. That should get you higher ( =

What is the room temp?

IM telling you man, you gotta get some more exotic cooling in there.

craigslist is what you need.

Buy a 5000btu window ac unit.

Or you can buy the window ac unit and turn it into a slush box to get negative temps. Theyr super easy to make.

all you need is a cooler, some anti freeze , and an a/c unit

Hmmm...... A slush box would yield lower temps, But whatever you want.

Its actually really simple.

1. Buy a 500BTU a/c unit and a cooler.

2. Open up the a/c unit and take off one of the fans.

3. Then take the evaporator and bend it so it fits in the cooler.

4. Cut a hole in the cooler for the pipes that go to the evaporator

5. Put the evaporator in the cooler.

6. Fill up the cooler with antifreeze.

7. Cut some holes in the cooler for your watercooling tubes.

8. Put your tubes in the cooler.

9. Set up the pump etc etc.

10. Mount the CPU waterbloack on the spu and hook up all the pipes.

11. turn the ac on and enjoi negative temps.


I can draw you a picture when i get my new motherboard. But for now im on my mac computer so i cant draw a pic.

No man.... its been around a while.

Its a form of phase change. Some people call it chillers. But it will give you well elow zero temps.

Personelly i like the high speed. But if you dont like it loud than stick with the medium. Thereis no point in getting the low speed ones because CM fans will go just as fast.

oh i guess order some of the medium fans when ever i get payed. Will there be any noticeable difference between the CM fans i already vs. the Yate Loon ones?
