I OCed my newly acquired lapped Q6600 to 2.8ghz, I tried to go higher, so I set the vcore to 1.425v in the bios, which showed up as 1.375v in cpu-z, I can't get much higher stable and am not really dead set on getting an insane OC with this cpu, so I have dropped the vcore down a few times and am now at 1.264v and my temps are almost the same (high 40s), shouldn't my temps have dropped more than just a few degrees...?
 
what kind you go bro. G0 stepping? or b3? if you try to overclock, vcore is not the only way to do it. you have to set your NB and SB. set your FSB. DRAM.

-skyyless
 
let me give you what i set my stuff in.

ASUS P5Q3 Deluxe WiFi-Ap@n
Intel Quad Q6600 G0
ASUS Silent Knight AL CPU Cooler
Kingston Hyper X DDR3 1375MHz 2x1GB
OCZ Memory Cooler
XFX Black Edition GTX 260 666MHZ[Stock]
2x Vel. Raptor 300GB

Here this might be able to help.

AI Overclocking: [Manual]
CPU Ratio Control [Manual]
CPU Voltage: [1.25v]
FSB Frequency: [333]
PCIE Frequency always: [100]
DRAM Frequency: DDR3 1375MHZ
DRAM Command Rate: [2T]
DRAM Timing Control: [Manual]
Memory Timing: 7-7-7-20
DRAM Voltage: [1.7v]
FSB Termination Voltage: [1.20v]
North Bridge Voltage: [1.25]
South Bridge: [1.05v]
C1E Support: [Disable]
Mutiplier: [9.0]

BAM 3.0GHz

Just switch a little things from 3.0GHZ

CPU Voltage: [1.31v]
FSB Frequency: [389]
DRAM Frequency: DDR3 1333MHZ
FSB Termination Voltage: [1.40v]
North Bridge Voltage [1.5v]

3.5Ghz bam!

it should be able to drop... check your thermal paste.
 
Are you talking about idle temps or load temps? If idle, you wouldn't see much of a drop since there is little difference between idle power usage across different voltage settings. Under load, you would most likely see a difference.

idle, I had temps in the 30a a week or so ago and now I can't get anywhere near 30s, high 40s idle, high 50s, low 60s under load, I just got my 775 bolt through kit and installed it because someone suggested that the push pins may be loosening up and not getting a good enough connection with the cpu, but the temps are still the same...

I may just set my cpu back to stock to see if that's why my temps were in the 30s before, the temps in the 40s didn't show up until I tried to bsel mod the cpu and when that didn't work just said "fuck it" and OCed a little bit the conventional way...
 
Idle temps don't mean a thing. As long as your load temps are okay, there's no reason to do anything other than leave it the way it is.
 
I think I may have figured out what the problem is, somebody please let me know how feasible this explanation could be...

when I start my computer with the case open, the temps drop when I press down on my heatsink, could the lapping have taken too much off and is there some kind of thermal pad that can add that lost height back to my cpu...? I have it OCed to 3.0ghz now and the temps are in the high 50s/low 60s, I put the pushpins back on because I added a push fan to the back with some zip ties and I can't access the screws for the 775 bolt through kit...

but back to the question, can a cpu be lapped too much...?
 
Generally speaking, you can't really "over-lap" a CPU chip. Is your heatsink lapped as well? If not, chances are it's not making good contact with the heatspreader of the CPU.

no it's not lapped, it could be hard to lap though since it isn't a solid one piece heatsink...

It sounds like the issue is not that you lapped too much, but that the weaker clamping pressure from the push-pins is reducing your contact, which is why it helps when you push it down. If you could manage to get the bolt-through kit back on, that would probably improve your temps.

I didn't lap it, I bought it that way, and it looks to me that it wasn't lapped by someone experienced either...
 
If more pressure on the heatsink lowers the temps then yeah you're having a contact problem. I wouldn't use a thermal pad or anything like that, but I can't think of anything else useful right off hand to help you get more pressure on that chip.

And 3Ghz is excellent for a B3. I've really had to push mine hard to get to 3.2Ghz. Running Prime, the temps can go as high as 74°C!! :eek: I'm risking it but o well. It's ez to replace.

it's weird, I couldn't hit 3.0ghz before, but when I decided to add a push fan to my heatsink I used zip ties to add a small fan to my northbridge heatsink as well and voila, it booted up at 3.0ghz at 1.328v the first time I tried after the mod, I don't know how stable it is yet, it hasn't reset or given me any problems but I had to stop prime about 5 seconds into the run because I was about to reach triple digit temps :eek:, yeah, it's that bad, the four cores idle around 50-57c and the temps just skyrocket when I put any kind of load on the cpu, I encoded the newer Bleach episodes for my kids with winAVI and it was hovering in the 80s and even popped into the low 90s at times...

the bolt through kit made no difference at all when I put it on, none, if anything the temps increased, maybe the chip wasn't lapped evenly...?

update:

I opened up my case again to see if gobbing on more AS5 would help, in the process I didn't like the way one of the pushpins was sitting, it was technically locked down, but didn't look right even though the heatsink didn't move when I grabbed it and tried to move it a little, then I turned it on and noticed the newly rigged up push fan was not moving because my IDE round cable was pressed up against it...

so...
1. I basically covered the whole surface of the cpu with AS5...
2. I took out one of the pushpins and reinstalled a spare in it's place...
3. I moved the IDE cable to allow the push fan on my heatsink to spin...

I don't know how much affect each had on the result, but now I am idling in the low 40s and high 30s, does cooling the northbridge really have that much of an impact on overclocks...? push pins coupled with push and pull fans FTW...

now to run prime...
 
it passed prime and the hottest it got was 69c, looks like everything is fine now...

thanks for your help/suggestions everyone...
 
Good deal.

And yes cooling the northbridge does help. I added a few more fans to my case, one blowing right at the memory and NB and it did in fact help.

Enjoy your speeds. :D
