I have a core 2 duo e6600 and asus p5w deluxe.And i am right now at 3.2 at 1.4875 vcore and i would like to reach more.So is 1.6 vcore and mch 1.65 very high for my pc.Is it going to cut m cpu a lot.I wont overclock it now but i plan on getting the new 8900gtx and i don't want my pc limiting it.

More about : vcore e6600

1.6 vCore is very high.
What are your temps?

I am running my E6600 at 3.4 GHx and 1.325 vCore
Temps using TAT are 56c under 100% load in both cores

Check out the core due temp guide at the top of this forum

DAM, how did you get to 3.4Ghz with 1.325Vcore? I'm running at 3.2 at 1.425Vcore. When i try to get higher i have to increase my voltages by a lot, for me to reach 4Ghz i had to put the Vcore to 1.625 and it was unstable :evil:  whats your multiplier and FSB set at?

Thanx L8er :)

cpu frequency is 378 and a multiplier of 9 = 3.4 GHz at 1.325v

I was able to get a cpu freq of 366 = 3.3 GHz on stock voltage of 1.275v
February 18, 2007 5:56:31 PM

Dear god man.. im running my 6600 at 3.29 with stock voltages... The voltage is at the norm 1.2.. im having no problems at all. Right now im sitten at 365 FBS with 9x multiplier. The higest i could get was a 480 FBS with the multiplier at 6x and all that was with stock V... Crank down your voltage then oc.. when ur comp craps out on you then up the V.

*note im using a Gigabyte 965P-DQ6

And yes 1.6 is stupid high.

Also my temps are 31 idle and 55 load. Take or give a degree.

oh, i'm running at 400x8. this way i use all of my ram speed and get a nice 1.6Ghz FSB. i'd like to get to 3.4 but my ram cant seem to go farther then 800Mhz; i guess i got the bad batch. Oh, and i wont go past 1.525 since 1.6 is "Stupid high"

L8er :) 
February 18, 2007 6:29:40 PM

I suggest trying your multiplier at 9x and set your FSB:ram to a ratio of 1:1

Also, I have my MCH set to 1.65v (stock is 1.55v)

Try those settings and increse your FSB . This combination will not "top out your ram speed" but the higher CPU freq shpuld more than compensate.

Higher Ram speed is 'over-rated'
Going from 533 c5 to 667 c4 only added 2% to my Prime95 bench

Good luck

I wasnt trying to be a bastard. If you have a way to cool it, go for it. Just the 1.6 seems like way to much for what your getting.

If your haven trouble with the ram, have you tried up'ing the timing? or the V for the ram.. i know its simple but sometimes people miss it.
February 20, 2007 5:16:37 PM

1.6 is high but is it going to kill my cpu life?I tried everything and i acnt pass that 356 fsb i have no ideao why also my ram i can overclock over 800mhz its just not stable dont know why.Should i mabye lower my mulitplier and move up the fsb or not?

You have a stable overclock at 3.2 Ghz with 1.4875 Vcore. That particular E6600 is giving you all it's got.

I answered all these questions, as well as many others, so yes, you should know why, because you were provided with more than ample information.

3.2 Ghz is the best you're going to get from your particular E6600. Here's the explanation again...

Quote:
There are no solid state devices 100% identical. Every silicon semiconductor is unique, and has different basic properties of electronics such as resistance, capacitance, inductance, impedance, and transconductance. Although two consecutive serial number CPU's from the same fabrication, with the same stepping codes, may appear identical, they're yielded from different location on the silicon wafer from which they're manufactured, and like diamonds, each has it's own unique flaws.

Even though their dynamic operational characteristics may be very similar, no two CPU's will overclock to exactly the same stable maximum speed, at the same Vcore, at the same temperature. Additionally, in a dual core processor, one core will always become unstable before the other. Your particular E6600 is simply not "clean" enough to reach any higher than 3.2Ghz and maintain safe temperatures. That's just the luck of the overclocking draw.


The facts haven't changed. Some E6600's can reach 3.6, some can't. You've got one that can't. It's just that simple! If you insist upon reaching 3.6 Ghz, then buy a half dozen E6600's and overclock them. :idea: Keep the CPU that reaches 3.6 at the lowest Vcore, and eBay the rest.

Incidentally, there is always a space between the end of a sentence, and the beginning of the next. :roll:

ok but your not the best guy in the world with computers so thats why i asked other people.
February 21, 2007 11:35:02 PM

Hey guys,

I ran my E6300 at 1.675V and 3.6 GFHz last night and there was this wierd smell and blue smoke coming out of my PC case.

Does this mean I need better cooling?

Or should I drop the multiplier down? I really need to reach 3.8 GHz so please help. TIA.

hey is it possible for my p5w deluxe to run vmch 1.65 without putting the fan on the northbridge?

Without modding my mother board in another way.

Yes, but the northbridge chipset will run very hot, which does not enhance FSB stability at 400 Mhz. At least consider removing the shiny and decorative, but rediculous heat dissipation inhibitive cover. 8)
February 24, 2007 9:26:03 PM

1.6V sounds a little high for a regular overclock.

don't want to highjack this thread but what Is TAT, I have seen this a couple of time. Is this a temp monitoring software and wyhere can I get it ?
February 24, 2007 11:39:23 PM

This is off the topic but i would like to know if a antec neohe 550 would run an r600,8900gtx or 8950 gx2?

I cant find an answer anywhere thats why i am asking.
February 25, 2007 12:21:38 AM

hes pretty much on target. not all are equal. its like a factory making cars. some cars for some reason are more lemon than others.
February 25, 2007 4:48:56 PM

so what 1.6 vcore is killing your cpu or the heat will kill it.So if you have a way to cool your cpu when at 1.6 you should go for it.It wont damage the cpu at those voltages?
February 26, 2007 1:57:12 AM

to computronix.
u seem pretty knowledgable so i ask u but other may reply on this aswell.

i am a newbie on OCing.
i have the same cpu and mobo as u and i wanna OC it to max. just wondering what are you steppings? i am assuming u r running stable at 3.7ghz.
your vcore, fsb, multiplier, cpu cooling, etc. i'd really appreciate it.
also, what are your temps.

Stepping = 6
Revision = B2
Vcore = 1.5125
FSB = 411 Mhz
Multiplier = 9
Ambient = 22c
Tcase = 53c
Tjunction = 69c
Load = TAT 100%

Hope this helps. 8)

can someone answer my questions?Does 1.6 vcore kill the cpu?How about if you get temperatures in the mid 50s with 1.6 is it still bad?
February 27, 2007 1:07:34 AM

yes it will. that kind of increase will destroy the lifespan of your cpu. anything over 1.5 really is too much.

The topic to which you're refering is Electromigration. As Vcore increases, temperatures increase, resistance increases, electomigration becomes more prevelent, and stability decreases.

The following quote is from the overclocking section of the Core 2 Duo Temperature Guide:

Quote:
...Intel's Thermal Design Power (TDP) spec of 65 watts can be exceeded by over 50% when CPU frequency is aggresively overclocked, and Vcore is increased to maintain stability. Intel's Vcore max spec of 1.3525, when increased much beyond 10%, or 1.488 Vcore, makes it challenging to maintain safe temperatures with air cooling. Also, as ambient temperature increases, overclock frequency and Vcore must decrease.

Every CPU is unique in it's overclock potential, voltage tolerance, and thermal behavior. Whatever the stable overclock frequency is at 1.35 Vcore, each increase of .05 volts will typically allow a stable increase of ~ 100 Mhz, and will result in a corresponding increase in CPU temperatures of ~ 3c...


Although CPU's are designed to last 10+ years at normal Vcore, most experienced overclockers agree that 1.6 Vcore is NOT recommended, and may result in permanent damage. Extreme overclocking much above 1.5 Vcore typically requires liquid cooling to maintain safe temperatures, upon which stability depends. When Vcore is incresed from 1.35 to 1.6, temperatures may increase by 20c. 8O

now how does that temp. both tcase and tjunction compare with the thermal specification of e-6600 , which is 60.1 deg? i guess i am not sure what that figure represents... i was under the impression that going higher than that temp would mean risking the chip to fry or atleast reduce the life span.
February 27, 2007 9:17:26 AM

hmm after reading the guide... well half way thru anyway it becomes evident that tcase is the temp that is shown in the bios and in some other apps like speedfan. and your temp at tat 100 % is 53 which is a little past the safe zone but at 3.7 i guess thats not too shabby huh. nice
accordin to that article safe zone is at 50 deg. celsius. 55 is warm and 60 is the hot limit. so basically u wanna stay around 50 for day to day usage as your temp at full load.
i am already feeling more confident about OCing my e6600. thanx computronix.
February 27, 2007 12:58:58 PM

I wouldn't put vcore over 1.5.
Also stability is more important that .2Ghz clock.
I'd settle.
I don't think your cpu will be the bottleneck/a bottleneck.
RAM will likely be an OC bottleneck at some point.
Simply upping vcore isn't always the answer.
February 27, 2007 6:16:39 PM

but lets say i get water cooling then i could set to 1.6 when temps are not going to be the problem
February 27, 2007 6:37:48 PM

I would not suggest them still as that is a lot of electricity flying around outside it's channels but so long as it's stable and cool it won't be too bad.
You shouldn't have to up it that much though.

I'd save the money on watercool etc and plan on upgrading it in the future or getting a better video card later on.

Yes. 1.6v can shorten the life of your CPU. As a common rule with overvolting, never go more that .2v above stock voltage without crazy cooling. And, even with crazy cooling it will still shorten the life.

Crazy cooling = phase change, really good liquid system
