TPU's Core i7 Overclocking and Feedback

[trt740]

Yep, that's how it goes. The D0s will pull less watts from the PSU as well, but they'll still throw off heat like WTF.

this is true they run hotter than C0 chips.

dilemma guys.

You know I got this new CPU and all that. but there's something I started to think about and couldn't get it out of my head.

I want a cPU which does 4,2 ghz under 1.27v . (currently I have 4,2 Ghz with 1.2875 Vcore).

Am i spoiled or do you guys think I just need to shut the fuck up and be happy with it.

I can still send the CPU back to the webshop and order a new one.

IMO your starting to get greedy... No problem if you can do so by tweaking to the max, but if your going to change chips just for that... no

I say, try to lower voltages with many other tweaks... might have what you want... btw I find you think D0 is a HUGE change from the C0/C1, as if it should do better no matter what... Chill and understand you have a great chip

Also, if you get much lower voltages for 4.0ghz, I suggest you keep 4.0 instead

great job fit with the vantage runs and the CPU clock.

I ask you, what was up with the vantage runs, what was the problem that was causing you the poor scores?

I need help getting my i7 920 stable. I have it at 4.0 GHz straight, 1.440 volts to the CPU, 1.9 volts to CPU PLL, 1.35 volts to QPI, spread spectrum disabled, and 800 mV differential amplitude. It always blue screens before it hits 70 % on the 1024m test option for wPrime. Any help guys?

Well what I do when overclocking.

set voltages to high range to ensure stability. Then lower the voltage till it gets unstable.
In your case I find the QPI voltage rather low.

yes it takes time but if you do it this way you'll know the best votlages for you overclock

Ok I did a OCCT test but OCCT stops because it says my CPU it getting too hot?!

Settings

21 x 200 @ 1.2875v
x36 QPI , QPI 1.34v
Uncore x18 = 3600Mhz
Dram = auto
QPI PLL = 1.28v
CPU PLL = auto

My case:

antec P182.

Front : Noctua NF-S12B FLX @ 900 RPM
CPU cooler Scythe mugen 2 with MX-2 , 1 front cpu cooler @ 1300 RPM , one at the rear @ 800 RPM.
Rear case fan : Noctua NF-S12B FLX @ 900 RPM
Top fan : Nexus Real silent @ 600-700RPM

What the...?

It stops at 80 degrees celcius?

Damned, how can this cpu get so hot. Even with all those fans, unbelievable . i think i really have a shitty batch.

What should i do guys? Any ideas on this matter?

Edit : ok I adjusted the max temp in OCCT to 90 degrees celcius. Let's see now.

So I spent half of my day lapping my heatkiller and 920. Temps dropped from 30c to 23c. Simply astounding. I'm glad I took the time to do it.

any pics?

 

[Fitseries3]

lapping a heatkiller is a HUGE NONO!

YES i did it but i found out that you have to do it a very specific way to not fuck it up.

im not saying you did but i want everyone to know NOT to lap their HKs

 

[N4cot1c]

no camera. as soon as I get a memory stick I will get you guys some pics.
My bios says 23 buy speedfan says 27???

Fit, I got a temp decrease so it worked out fine for me. I am not one to listen to people a lot. I like to try out things for myself and if I fuck up oh well.

 

[Binge]

for some reason superPI wont run on this machine. even at stock clocks it errors and closes.

Disable audio drivers. It's a common bug.

 

[Fitseries3]

oh i disable everything except 1 lan port. EVERYTHING

 

[Binge]

Drivers fit. Not hardware. Drivers I believe you but I have to state that error because it's a common super pi bug.

 

[Fitseries3]

if its disabled in the bios, its practically not there. OS doesnt even see it.

 

[Binge]

I've still had to disable it. Accept the file transfer. I made batch files for it that read as follows:

soundoff.bat
net stop "AudioSrv"

and

soundon.bat
net start "AudioSrv"

Why is that? Where is that info coming from? I've never heard of lapping doing harm unless it was done improperly, or tried on a piece of metal that as too thin. Especially if the cpu is lapped perfectly flat as well.

 

[Fitseries3]

im banned from RRR.com but you can see it there.

there is a thread all about not lapping the HK3

the block was machined with a slight curvature.

if you lap it you'll remove the curve.

if you lap it with the block together like alot of people might... the block will be flat until its mounted on a cpu then you'll have a bubble in the middle where the block actually curves away from the cpu in the middle. i guess it would be better described as a "pocket".

if you lap just the base alone... copper only... you'll have the flat base even when its on a cpu.

HOWEVER...

the HK3 is SOOOO thin that if you lap too much off you'll sand clean through the base.

HESmelaugh(shane) and hondacity both know from experience.

they have both noticed worse temps in the 1st case but were able to fix it to correct the problem.

Ahh, so they purposely have it bow when it's mounted, AND it's also thin. Now it makes sense.

And, if I am gathering this correctly. When not mounted, the HK3 is convex (when viewed from the outside). When you mount it, the pressure from doing so actually makes it flatten out on the IHS.

+1 ftw you got it Wile E

if that is correct, that makes a lot of sense

OMFG temps?

OMFG temps?

No idea, but I guess they were very high 60 degrees or something
