View Full Version : Need Guidance Overclocking E6600 Core2Duo
I have been intrigued by overclocking for a while now, and I just built my own custom rig so that I could learn and overclock successfully as so many here does.
I have the following components besides the Intel E6600 Core2Duo.
ABIT IP35 Pro LGA 775 Intel P35 ATX Intel Motherboard
http://www.newegg.com/Product/Product.asp?Item=N82E16813127030
Patriot eXtreme 240-Pin DDR2 800 (PC2 6400)
http://www.newegg.com/Product/Product.asp?Item=N82E16820220144
XFX PVT84JUDD3 GeForce 8600GT 256MB GDDR3 PCI Express x16 Video Card
http://www.newegg.com/Product/Product.asp?Item=N82E16814150229
Amnd attached is a screenshot of my uGuru program,that is from the Abit motherboard, which shows the clock speeds and voltage settings.
Problem is that even if I set the clock speed to 273-275 the system starts ndomly rebooting while programs run. I tried also to raise the VCore voltage to 1.37V, but it didn't help.
Please guide me so that I can learn...:bang head
I tried looking for a thread with a thorough explanation or guide but didn't find one...maybe I'm not looking in the right places...:confused: :(
Anyways...Any and All guidance would be most appreciated. :beer:

So many users on this forum have told me to read the stickies, but I'm too stupid to do that. I'll just mess around until something explodes and cry myself to sleep. :D
Abits tend to undervolt a little. Try bumping up the vcore to 1.4v if you have good cooling. Speaking of which, what heatsink are you using and what are your load temps? Also, bump up MCH and ICHIO voltage one notch. I'd set the memory voltage to 2.0v.
Thanks AzAzEl656 and batboy,
I appreciate the input and recommendations.
I'll read up on the link as well as the thread I just seen about Intel Quads and Duos.
Then I'll try out batboys suggested settings...
Thanks
As for my temps...here's a screenshot of uGuru
...the CPU heatsink is the stock one that came with the e6600.

@ batboy...:thup:
Thanks mate,
the voltage settings you recommended seems to be working well. I have overclocked to 2.5 GHz without any reboots and the temps are staying very low and basically didn't bump up at all while I worked with compressing video.
I plan to proceed forward in baby-steps towards 3.0 GHz, while I continue to learn what eveything means and whats best to set.
I appreciate you pointing me in the right direction....:beer: :)
screenshot of my temps...
2.65 GHz and climbing..:attn: Very stable and temps are 35C CPU, 32C system, 4.1C PWM...In the middle of a hot afternoon..lol
Thanks again guys, I appreciate your help.
Hope this thread helps others who may get the Abit and E6600.. :beer:
I'm guessing those temps you posted are probably idle. Run Super Pi or something like that and see what temps do under load.

I was checking those temps throughout video editing @ 50% CPU usage?? (not sure if that is considered idling... LOL) Never moved much up or down...maybe a couple each way and only for short intervals.
I don't know if having an Antec 900 case makes the difference in keeping this system so cool, but it does have the 4 case fans and the wiring I have keeps the inside of the case very spacious...
What does SuperPi do??
Don't know how to read this report from SuperPi, but here it is...:confused:
BTW, I cranked it up to 2.7 GHz and used DVDShrink, which ups the CPU usage to around 90 %, and I did get a beep from the system...even though the uGuru showed temps at 42C CPU, 36C system, 47C PWM...
Not sure why since I was under the impression the beeps were supposed to happen when the temps got much higher???

Get Orthos to test your temps, and CoreTemp v 0.94 to read temps. (google to find them)

I wouldn't trust uguru's information...

Thanks for the info about those utilities. Really worked. CoreTemps recieved readings of 60C from both cores at 2.65GHz while running Orthos.
Funny thing is that uGuru finally started showing the temps similar to CoreTemp when Orthos started running. Guess batboy was right in stating that the uGuru temps I posted earlier was still reading idle temps??...
Thanks guys...it's fast becoming a very enlightening learning experience for me...I appreciate all the input. Guess I'll be looking for a good CPU heatsink and fan to replace the stock one...lol :beer:
Better cooling will certainly help get you a good overclock.

also bump you pci-e speed to 110, then bump your cpu GLT %'s to 75%, both of them.
what ram ratio are you using?

60 deg is a bit hot if you get a good hsf you should be able to do 3.2-3.5 ish no prob
and just waite till you start clocking that gfx card =) i have mine with mods running 900+core 900+ mem

Thanks for all the guidance guys, truly appreciate it.
I will try all the settings you guys have suggested, and if the temps still go high only at 2.7 GHz, then I will have to look into a better cooling option...:( :)
what ram ratio are you using?
I remember reading about setting this, but for the life of me can't find where in my BIOS??
I may have to re-read what I have to find where this is discussed...been reading alot of different things and dont remember which thread had what..

If you have cpuz installed it will tell you the ratio that you are at.

Thanks...
it's 2:3.
You will need to change the memory ratio or else you won't get any higher. Go into the BIOS and set the strap to 1066 and the next setting below that set to 1:1 for now. That will keep the memory from holding you back.

Thanks batboy, I'll be sure to find it in BIOS and adjust it.
But I'm thinking that at this point I don't want to subject my Core2Duo to unnecessary heat for it's prolonged life, so I gonna take a break for awhile until I figure out what better cooling I'll decide going with.
I have learned an enormous amount and I feel much more enlightened to this whole process. I thank all who guided me, I appreciate the tutorledge.
Cheers mates...:beer:

My BIOS doesn't have that 'strap' setting you are talking of. it just has the setting to go 1:1, 1:1.25, 1:1.50 (default 844), 1:1.75, etc......

your ram ratios should looks like this.
http://img.photobucket.com/albums/v733/Evilsizer/ocforums/Abit%20IP35-pro/ramratios.jpg
we both have the same board, i would use 1:1 for the time being.
Ok, I just assumed the BIOS was like all the other Abit mobos I've messed with, I see it's a little different. You probably could use 1:1.2 for now, then once you reach 333 FSB, set it to the 1:1 ratio.

yea p35 boards abroad dont have fsb dividers. Some of us are hoping abit will add that into the bios.
My 1:1.20 shows (DDR2 662) or something like that...is it supposed to be what yours says Evilsizer?? or will it change as I up the FSB??

whats your fsb right now? the easiest thing you can do is this, FSB*1.2=ram speed. ie 266mhz*1.2=319mhz then multiply that by 2 and you get 638mhz. its gonna show what your ram is running at per the cpu fsb and ratio used.

It's running at 225 FSB x 11.5 or 369 FSB x 7.0...I rebooted and it reads DDR2-688.
I'm running at almost 2.6 GHz (I meant 2.6) and the CoreTemp program is showing anywhere from 34C to 41C as I open apps.
I also haven't done this setting yet...is it vital to??
also bump you pci-e speed to 110, then bump your cpu GLT %'s to 75%, both of them.
If you are at about 2.6 gig, then you are probably running 9X and 287 FSB. The 1:1.2 ratio will give you a memory frequency of 344 which if you double gives you DDR2-688.
If you are going to stay at that CPU clock speed until you get better cooling, then you can probably run the RAM faster until then. Trouble is 1:1.5 is too much unless you go back to default speed. Try 1:1.25, that's good for up to 320 FSB while still running your RAM in spec.

you will want to set the pci-e speed when you start oc more. the CPUGTL is what you wanna up before you touch the CPUVTT voltages.
FSB now at 243 x 11.5...2.8 GHz, and system seems very stable and temps are ranging from 35C to 41C while some apps are running.
Seems that setting the ratio to 1:1.20 made a difference so far.
You guys are da BOMB!!! :thup: :clap:
I've learn sooo much this past few days...can't thank you guys enough..:beer:

Well, there is no 11.5X multiplier. Your E6600 has a max multiplier of 9X, although it is possible to set it lower. At 2.8 gig, you probably are running 311 or 312 FSB. Check CPU-Z to confirm this if you want. I would not believe that Everest program.

Bro, you're really on it!!! Yes CPUz did report the FSB as 311, and I did see in BIOS that it is 9X...Somewhat disappointed in Everest, can I trust any of it's info??
Anyways, here's a screenshot of CPUz @ 313 FSB, the only thing is that it reports only for the core speed of only the Core#0 ? not sure why.:confused:
Cheers mate, for all your 'Sensei'-ing...:D :)
You can trust everything in CPU-Z except the voltage. It won't read Abit's uguru vcore right. The reason your CPU-Z screenshot shows 6X multiplier is because speedstep dropped it down at idle. Once you give the system a little load, it'll jump back up to 9X. You can disable EIST and C1E in the BIOS if you want or just leave it. Oh yeah, if you want to see the other core, there is a pull down menu at the bottom titled "selection" where you can choose which core to monitor.

Yeah the selection part is greyed out.
And you're right, when I start putting some load on the system, CPUz does report the 9X and the FSB.
batboy, Evilsizer, as well as all others who helped guide me, I can't thank you enough. I really learned so much already and genuinely appreciate being taught how to overclock this system correctly and efficiently.
With your guys guidance I have already cranked it up to 3.0 GHz with the stock heatsink & fan, with the temperature barely going into the 40Cs while doing most of the video and DVD work I do. And with a little more load put onto the system it still stays in the 40s to mid 40s (just goes above 50 while using Orthos)...so Thanks again for pointing me in the right direction...can't wait til I put in better cooling!!
Cheers Mates!!...:beer:
One last question...the memory timing is at 5-5-5-16, is that OK or should I change it?? to something like 4-4-4-12? Someone at a Video forum kinda mentioned this timing...
Seems to be running fantastically at the 5-5-5-16, but just wondering.

what fsb are you running and what ram ratio?

I was running it at 334 FSB and 400 for Memory at the time (1:1.20), it was @ 3.0 GHz. I have since toned it to 2.7 GHz for the time being.
if you are running 333 FSB and have the memory ratio at 1:1.2, that will give you exactly DDR2-800. If you have the Patriot RAM that you listed in your first post, it should do 4-4-4-12 with 2.2v. I would try running tighter timings (lower numbers) and see what happens. Make sure the memory voltage is 2.2v though.
EDIT: If you backed down to 2.7 gig, then definitely try 4-4-4-12 timings.
