Finally got 2nd E6750 relapped with beter efforts. I also removed the X38 chipset IHS for added improvements and is already doing great. Fan from RAM cooling helps otu a bit too.
Settling for daily use of 3.80GHz as 480x8 in 5:6 @ DDR1153 @ 5-5-5-13. Will be comparing it to my 500x8 on 5:6 DDR1200 @ 5-5-5-15 shprtly.

why not try to take off the heatspreader of the proccessor?

I don't suppose anybody here knows about overclocking with crossfire do they? I should have that opportunity in a few days' time.
Shaff: I know you mean respect, but would you mind removing that from your signature? I don't really want to be reminded every time I post.

Shaf, taking the heatspreader off would probably not be a good idea. First of all they are soldered on there, and even if you manage to take it off safely the chip is very fragile. The heatsink would probably crush it in no time. So it's good to leave the IHS on.

Very nice polish 'bling job' on that CPU.
I would however never take any lapping to that extreme, as anything over 600 grit actually tends to have a detrimental effect on heat transfer, all that is needed is flatness not mirroring.
Just thought I'd point that out as it?s a lot of hard work which won't have any benefit to cooling, I used to go to that extreme myself until I realised it wasn?t required and wasn?t doing any good.

sorry sam. i have removed
and azubar, they arnt soldered, they are shut by glue, via silicon filling.
(just knife it)
and with screw on HS (ala most that arnt the Intel or freezer pro 7) you can choose how far you want it to sit.

Just to add to your post, it also voids the warranty on the CPU. If Intel can't read the numbers on the heat shield, no warranty!

CPU IHS
I did remove the NB chipset IHS since it doesnmt get a lot of weighted wobble. But yes the CPU IHS does come off just as easy and is or does have some thermal cement to die but is easily removed by Isopropanal, Ethenal, or Ethal Acetate or all of the above in combo cleanres. A controled drip inside one slit can be wiggled right off, and will finish lossening the glue surround as well. So yes of corse I did try this on another Core 2 and it didnt look sturdy enough to mount like that. The cool thing is, if only using the formentioned cleaners to remove (no knife), it was a snap to put back on as all you needed to do was redesolve the glue and melt back together. I did use Artic Silver Industrial cement inside (die to IHS). So this helped a 2c extra.
However the issue is not the weight so much as it is the shifting of the weight as is expected in verticle mounting. It would might be fine in a desktop or cube stacker and especially on water cooled. Lossening screws on most will not help as most retention barckets are suing springs so the weight is balanced overall, and you will only cause it to be more proned to wobbling and creating more stress on the die.
This was more so needed on A64 and was simple on 939 on since there was no weak center area to worry about and as long as you have a sold metal back plate, you were set to go.
As for the CPU mirroring, I did just make sure it was flat, and only gave it a shine cause it looked nice and actually used the silver compound to buff it with non static felt and it came shiny on its own with lil' effort. I only went 1000 on final and buffed the reston flat granite block under felt and flannel.
Additionaly; I dont know about Intel, but ASUS doesnt care or look inside. So it is easy to do the same with the x38 chipset IHS as well. I have mine to glu back if needed for another RMA.

ck: Lol, I've no need for the watercooling rig, I've overclocked my single card higher than that using the reference cooler it comes with, and at nowherenear full fan speed (55%). The reason for the high score though is the 4.5Ghz 45nm Quad. With a 3.15Ghz 65nm Duo I'm not going to be pulling anywhere near that score. I was hoping for a guide on how to overclock the cards independently in overdrive, I'm sure it can be done that way.

once cf is enabled in catalyst, you can go into the overdrive panel where there is a drop down that allows you to overclock the cards independently
I had my core upto 935mhz with the fan @ 65% too noisey for my liking , getting a duo orb for it so will be able to do that nice and quietly, got another card on the way , just deciding on what mobo / cpu combo now and a higher rated psu, have another £700 dissposable cash so im looking forward to gaming when i get it clocked up. reverted back to the origonal bios now as 8.3 cat is glitchy and has some issues in cod4, so lso back on 8.2 cat.

If I were you, I wouldn't bother with the Duorb. It won't be very quiet, and it's cooling performance will be adequate, but not exemplary. Get an HR-03GT with a decent 92mm fan on it like a Nexus. THEN you'll be able to overclock your card quietly.
Do you have a pair of 3870s running then or did you look this up?
If you do, would you mind telling me what games you run and how they do?

Who has a new Q9450 on the way? What about any good lab overclock reviews yet? How are you guys doing on the E8500 yet to play with.

I binned my order as the reviews of it tested side by side with the Q6600 showed no real gain to be had.

Interesting. Is this purely on the basis that the Q6600 overclocks further without going into the voltage danger zone? Or is it really the case that clock for clock the Q9450 isn't much faster? I was considering getting a Q9450 at the end of summer since they're so expensive, but if I'd do just as well with a Q6600 it may be far sooner than that...

At the rapidly dropping prices of the Q6600, I'd just get that if I were you. They have the ability to hit 3.6 on air. That's fast and you'll never even use all that power (unless bruteforcing passwords xD)

Well that's the thing, I've owned my E4300 for over a year and its lasted me quite well, still is. I don't want to get a Quad core that will end up massively outclassed in a short period of time because I can't afford to spend that much money on something that's soon replaced. Remember, I don't want to have high CPU temps, and I don't want to have a huge power usage, as it will ruin my nice quiet PC, but I do want to get sufficient performance to forget about my CPU being a frame rate limit in modern games.

This shows some basic stats between the two CPUs running at 3.6GHz each.
The main area of gain is in the power and heat (hardly a surprise).
http://www.xtremesystems.org/forums/showthread.php?t=173287
I am presuming that anyone looking at either CPU on this thread is looking to overclock it (hence title of this thread).
Looking at the two CPUs at stock speed is not going to show much other than the obvious, as the Q9450 is 2.66GHz compared to the 2.4Ghz of the Q6600, and then there is the cache size difference.
Other than that the main gain will come with SSE4 compliant applications, which should so quite a gain in performance over SSE3.
If I was buying one now I would probably go for the Q9450 over the Q6600, as it is slightly better in performance, runs cooler and uses less power.
I do however already have the Q6600 which runs 24/7 at 3.6-3.8GHz mood dependant, so for me there is no gain.
There are quite a few people that will be expection 4+GHz out of the Q9450, but that is very unlikely for most people, as they will struggle to get 500FSB stable. 3.6GHz should be pretty easy for most people, so you still get a good OC on your CPU, it then comes down to % gain to had compared to % price difference, with the Q9450 prices having increased recently making the difference up to +70% with a performance gain of about 15-20% when possible, it makes no sense to get the Q9450.

"the only difference was the the Q9450 vcore was 1.3volts whereas the Q6600 was 1.45volts" - is 1.3 the stock Vcore for the 9450? If it's managed to get from 2.66 to 3.6 at stock voltage that's great news, as based on what I've heard, I'm not going to be touching the voltage if I get a 9450. I doubt I'll be pushing much above 3.6Ghz on a Q6600 because of the power drain, and if the 9450 will be faster than a 50% OC on the 6600 without even touching the volts, I'm far more sold on the 9450 than before. It's time to save up... :(

but to get them to 4GHz, (thats what i menat) the FBS woudl ave to remain stable at 500FBS, and with voltages being weird on the penryns i doubt it will do that.
for 4GHZ the Q9550 would be better

4Ghz isn't achievable with the Q6600 on a sensible voltage either or so I've read, so unles you buy a very expensive CPU indeed, 4Ghz with a Quad isn't achievable on a daily basis by any means - it speaks volumes that a comparative expert like BigDK only runs 3.6-3.8 on it. Given the innate performance benefits of the Q9450, 3.3Ghz or so should roughly equate to 3.6 on a Q6600, and that seems relatively easy to achieve with barely any voltage increase, if at all (I'm not quite sure yet, I'd be loathed to even go near the voltage for a 45nm).
