Don't you know how to size a photo? You have the whole thread out of wack.

I think people could see it a little smaller

Nice mod fix though.

Personally i wish everyone would use thumbnails. Keeps the thread clean and people on dial-up don't have to wait forever to read a thread.

That is a very impressive OC. I would not have imagined, that you could OC that chip like that.

I need a 1000 w PS or it is the MB, my Vcore drops under load.


I have been working with a GO since yesterday. Also my DDR is holding me back. I is very stable at 900 MHz 4-5-5-12. But, that is all it will do at 2.3v. I went through that with the Dual core 9x. One thing I don't understand, when I loosen up on the memory timings, I get a OC failure.

I only have air cool, but I was not being held back by that before other problems failed.

re vcore droping on load - Have you disabled C1E, Vanderpool(if available) and Speedstep? What is vcore set to in bios? What memory have you got.

re vcore droping on load - Have you disabled C1E, Vanderpool(if available) and Speedstep? What is vcore set to in bios? What memory have you got.

It drops some. I have the Vcore set to 1.385. And I get 1.34 at idle and it drops to 1.31 under load. I want it to loop both Prime95 25.4 Torture Test and 3DMARK06 together indefinitely at that Vcore.

I keep Vanderpool off, and I had the CI and Speedstep disabled for testing.
I can get it to boot around 390 x9, 3.5 GHz. And I can even get it to run for a while, pass a few PI tests etc. But, it just does not have the stability I need.

I run this system 24/7 and also want to use the bios power management on my day to day use.

I run my DDR at 1.2v. I have not messed with the NB v, maybe I should up that a little. I don't even know what the default voltage is on that.

I think I am maxing out this PS. 520 w, with 2 RAIDs and a bunch of other stuff. I was hoping to get it up to around stable at maybe over 3.5 GHz.

But I will wait till the DDR3 comes down in price and get a new board and memory.

PCMARK05 on 10/11/06 with 2 core at just about the same speed.




This is one with the same 2 core CPU on 3/27/07 with Vista.
Look at the HD speed




This is a test the other day with the Quad under XP. By the time I ran this one at this clock speed it was late. I only ran it one time. Maybe a few more runs it would have balanced out more. It run's everything 2 times. So, it is like having two tests. One with the overall and one by line item.



I need to clean up my Vista install before I do a test PCMARK05 on that.

Most q6600's on air seems to need at least above 1.4v to get 3.6. I would try higher volts and if that fails try with higher volts and drop the multiplier to 8and try fsb450 1:1 with memory. I have pll=1.6,fsb=1.3,and NB=1.4 with vcore=1.4125v I dont believe that you want to use BIOS power management if you are overclocking as it will affect the stablity.

Dear sesdave,
I will try the the 1:1, I would have the same DDR speed of 900 MHz. 8x 450 ~ 3.6 ~ DDR2 900 MHz. That would work for the DDR. I have tested this memory, maybe a year now, and this is the best I can run 4 sticks with a somewhat acceptable timing.

Under Vista I have the Vista power management configured not to drop the the Vcore when the multiplier drops to 6x.

I will go up a little on the Vcore and see if I can have this overclock with the acceptable thermal result. The CPU should be OK since the Vcore spec is 1.372. I will go up to the Max spec and see it does.

Can you tell me what is the default NB v ? That would give me a reference. I guess I can just look that up. What is PLL?

Like I said, I want 110% stability with this computer. My default OS is Vista 64. Set up for Visual effect. I have a custom aero theme, side bar full of gadgets, TV card running, DreamScene, some FTP folders, and other TSR's. 24/7, not a good test OS. But I did run Prime95 for 8 hours.

Today I will order a OEM Vista Basic and dump the XP as my testing platform.
At this point in time, a fully loaded Vista OS is to fragile for testing. The registry and services is will not withstand BSD, bad shutdowns etc.

Thanks for the TTR's Guide, that is a real nice tool.








PS: I can also experiment with software controlled power management for day to day operation.

I am slightly confused - what speed are you trying to get the q6600 to run at for 24/7 operation. I will happily run mine 24/7 @3.6 without any power management as it only idles at 34c. Sure it increases under application/game load but nothing like running prime95 all day. As long as you have decent CPU HSF and a good airflow through the case it will be fine. What HSF have you got as 50c is a bit high with nothing running and underclocked.I would expect it to be somewhere between 30-40 on idle allowing for different batches.
Why you want to buy 32 bit vista when you have Vistax64 - you have a 64bit CPu and vista x64 runs fine. Seems a bit of a waste.
CPU PLL voltage is a BIOS setting on the P5K which I understand to be for fine-tuning the power supply of the q6600. Increasing the default setting can help stability of o/c with high fsb.

just got my G0, temps are about 7c different per core, with my ultra 120 extreme, i reseated the cpu with the washer mod, still the same, i dont think the bottom of the 120 is touching the cpu all the way down, any suggestions?

Temperature variance between cores is normal. You can try to reduce it by lapping the heatsink and the cpu.

Heatsink is lapped, the cpu i dont want to lap, i have lapped 5 cpu's with no difference to anything, temps stayed the same, and OC stayed the same, all with mirror shine to them as well.

Well.... My 'G0' was not flat(not even close). CPU's rarely fail so i wouldn't be so concerned about losing the warranty.

I know man, but the thing is i have lapped several cpu's with no gains, if any very small and not worth the trouble, so far the temp difference is 8c , core 0 and 2 run 8c higher than core 1 and 3.

sesdave,

I am just trying to have a balance of performance/stability. My power management only changes the multiplier not the Vcore. Are you saying that running Prime95 all day is to high a standard?

The temps at 50c are the core temps. Is the the Intel Thermal specification of 71°C the CPU temp? I read on an Intel PDF that on a 775 you have to have the sencer mounted directly in the center of the die. My CPU temp in that pic I believe was in the high 30s. But, on average it is less (See the pics)

I have an ARCTIC COOLING Freezer 7 Pro with 3 day old Arctic Silver 5 (different companies).

http://www.overclockersclub.com/reviews/freezer7pro/

After many re-installs, I just dumped a Asus VR-Guard cooler. It was just a big hot hunk of copper. I even added a additional fan and it helped only a little. I put the OEM fan back on and then went to what I have now and this is the best out of the three. The min temps are not the best, but, the max temps are fairly low compared to the other two. I don't think I have a CPU cooling problem at high load for what I am trying to do.

http://www.trustedreviews.com/periph...CPU-Coolers/p5

Before that I dumped CORSAIR XMS2 8500cs DDR. It did not run anything close to the claims on my board. I replaced it with what I have now and I have better stability, mem speed and timings. This mem is on the QVL list.
I can believe how much DDR2 went down in price in 3/4 of a year. And the DDR3 prices are way out of site. I bet they will go down substantially in the months to come.

I would not install Vista Basic 32-bit. I believe I have seen the OEM Basic 64-bit at Directron.com. Also, I have installed Basic 64-bit on 2 computers with the Windows 64-bit Anytime Upgrade disk and a Basic 32 valid OEM key. I want it to read 4 GBs of memory.

I Vista install I have now is not setup for any Benchmarking. I have been running Prime95 though for probably 1/2 hour and all is good.

I picked a Vcore of 1.42 and that is as high as I will go. That should be safe for long term use (yes, no ?) I am at 8x 430 3440 MHz. 1:1 860 mem.

FSB of 450, I had a BSD at boot, FSB 440 I ran Prime95 for around 20 min and had a re-boot.

Now I am at 430 and all is good. If I need to go lower, I am just going back to the 360 9x and stay at that. You can tell by my Video card that I am not a gamer. But, I am a big time multi tasker. Vista feels real go with this 4 core CPU. I really notice a difference.

I would like to find a way to OC a ATI vid card in 2D. Just a little


Here are more temps at 1.41-1.42v.

One 24hr run of prime 95 is more than enough to prove any system stability for MB,CPU and memory- it maxes the machine out way more than any normal use of multitasking will do. I have never bothered with more than a 12hour run but some forums demand it to prove your overclock. Depend on how keen you are - although as you want 24/7 use it worth doing.

Coretemps are what count. Here is a link to an article re tcase,tjunction and all thing temperature for CPU's http://www.tomshardware.co.uk/forum/...perature-guide
Your idle temps seem high -Whats your case cooling like. I had an arctic cooler 7 pro before the ultima-90 and it would idle 37c @3.6 with 1.425v using MX-2 paste. If the load temps of 60c are with prime95 running that looks good to me.

Dont give up on 440 just yet - uses other BIOS options than vcore to try and get stability. I use not only CPU PLL increase for stability . This is an interesting thread on how CPU Voltage Reference & NB Voltage Reference can influence OC- ability. http://www.xtremesystems.org/forums/....php?p=2461613 What make is your memory and what volts are you giving it. You could try loosening the timings to 5,5,5,15 first to get the system stable and work on it later.

Rivatuner is the tool I use for overclocking my 8800GTS - it has a 2D/3D option. Get it from guru3d.com. http://downloads.guru3d.com/download.php?det=163 good site for most drivers and tools.

I lapped my e6600 with no real gain but it seems a lot of q6600 are being reported as having a concave IHS. Check it with a razor blade light test - e.g get a razor or stanley knife blade and hold it on the IHS surface and see if it blocks all light along the length.if there is significant light showing you will benefit from lapping it - if not a waste of time. I checked mine and it was okay so I didnt do it. Here is a link that shows a 10c benefit when he lapped his concave IHS http://forums.pcper.com/showthread.php?t=441410
A mirror shine isnt the main idea - just get it as flat as possible for maximum contact -The paste will do the rest. I found upto 600 -800 grit black wet and dry paper was enough for an overall flat finish with all nickle removed- a last round with a 1000 if wanted but not necessary. Different grades of paper and a piece of glass is all thats needed. I see some people use water when rubbing - this isnt a car wing that we are rubbing down so no water!.Just use new sheets as required. That should drop overall temps and even core temps . Have you got a fan with a good CFM on your HS
