View Full Version : E6600 Speed Problems
Here is a shot of my CPU Z result.
What i dont get is the Bus Speed 266.7 x 6 only makes 1.6 GHz? why arn't i getting the full 2.4 Ghz. Yet in the BIOS it says its running at x 9 Multiplier. Ive just been watching it there and it occasionally flickers to x9 multiplier.
Any suggestions.

Lol... turn off speed stepping in your bios. It's changing multis to save power usage.

It's the Multi that has is down to 1.6... for the e6600, the multi is normally 9.

If its called Intel Speed Step its already disabled.
Any more suggestions so i can get this running at 2.4 Ghz constantly.
Look for something like C1 or C1E, I forget. but I think that will get you back to normal. if it doesn't have you tried manually setting the multi to 9x?
Fixed it.
what would you reccomend overclocking to? with stock cooler?
and how do i go about overclocking increase by 10Mhz then boot and check if everything is okay?
If you need to know about cooling in my CPU is rouchly at 45C and my system temp is rouchly 35C
For starters what are the rest of your system specs?
For starters what are the rest of your system specs?
Case: Xblade ATX
Processor: Intel Core 2 Duo E6600 @ 2.4 Ghz
Motherboard: EVGA 680i SLi
Memory: 2GB Corsair TWINXMS 5-5-5-12
Video: BFG 7950 GT
HDD1: WD 160GB SATA 7200rpm 8mb cache
PSU: Tagan 480W
ive just put them in my sig ive always been ashamed of my rig so have never put them in lol. :)
I'm not very familiar with the 680i chipset but like you said, a good start would be by raising in increments of 5 or 10. To do this go to where you see a place to raise the "FSB" or the memorys speed. (with the nvidia chipset it may be called HTT) Then whenever Windows refuses to boot bump the CPU voltage up a notch and try again. For a quick stability test you can do some runs of SuperPi. Oh and if you have the option go ahead and set your memory timings/voltage manually to what its rated. In your case, 5-5-5-12 and perhaps 2.0v.
If windows refuses to Boot will i still be able to access the BIOS. and how many volts would you recomend uping the voltage .05 or .10
Yes, since your motherboard is the first thing to start up. What do the CPU voltage options look like on that board?
I dont know what you mean if you can be more specific then maybe i could tell you.
Does it allow you to select the specific voltage, like 1.325v. Or does it make you do +.05, +.1, etc.
It already has the choices there for you to select.
well ive got it running at 2.6 GHz at 46C and i havnt touched the voltage.
Should i run a SuperPI test?
When doing a superPI test what k should i calculate.
Just keep your temps below/around 60-65C full load and you are fine. I think you will find getting rid of that stock cooler is your next objective. :) If you don't have these programs already:

I heard there is loads of issues with adding custom coolers to the 680i board.
Should i try for 3Ghz or jsut leave it?
I would keep going until the temps are limited to find out what you can max out at. Then from there pick a place where the temps are to your liking. Unless there are caps in the way I don't see why mounting would be an issue.
EDIT - I just searched around and apparently the Tuniq Tower 120 wont fit due to resistors. I'm not how this goes for the rest of the coolers out there.
on certain board versions there are capacitors and resistors in the way of where the backplate would fit.
I just asked my mate if i should try 3 GHz he said no because i only have a 480W PSU and it might burn the PSU out.
After a quick search of some reviews it looks like that particular unit handles its load pretty well. I don't think clocking up to 3Ghz will be a problem by your PSU.
Ive been told off loads of people that the 680i and e6600 are a dream to overclock especially when together

How old is your 680i board? The new rev boards (without raised components) started shipping back in January. Besides that, there are very simple workarounds to mounting a backplate with the older rev boards. I have done this myself, as have many others. See the following thread for details:

As inkfx said, that stock cooler will limit your OC potential significantly.

Your mate is pretty funny. :beer:
Overclocking doesnt add THAT much load to your PSU. Sure its draws a few extra amps, but nothing thats going to stress a PSU.
I have no idea how old it is.
on cpu-z it says its the rev= A2 is this the most up to date one?

You should be well within your tolerances. Check this for a rough estimate of your PSU load on your system. I punched in the devices on your sig and it was <300W even when overclocking to 3.6GHz and using 1.5vCore.

Youre just gonna have to do the old fashioned way... pull it out and look at the back.
Trust me, you will want to upgrade the stock cooler no matter what rev board you have.
I may get a Tuniq tower 120 but the size of the heatsink puts me right off.

Puts you off why, exactly? Its the large surface area that makes it such a good cooler. More surface area = better heat dissipation.
After using the Tuniq myself, I cant see myself using anything else. If you add a high CFM fan like a Delta, you can even rival most watercooling solutions. It's that good.
Ill look into it.
How much do they cost roughly in GBP.
and i shall not be on this rig for some time as i received memory today and one of the sticks is corrupt so having to RMA it.

I really dont know what vendors you purchase through in the UK.
Here in the US, the are found for around $50-$60 USD. So $50USD = approx 28GBP?
Bit pricey from here, but Newegg is my main parts place:

FrozenCPU is where I purchased my Tuniq:

You may also want to check out the Thermalright Ultra-120. If you can hold of a little while Thermalright plans on releasing a new cooler, the IFX, and update the Ultra 120.
Ill probably just get the Tuniq Tower 120.
Are they easy to fit? and whats it like for noise?
IM back on my step dads laptop as sent back the bad memory today :(
I found it a tad tricky to get it mounted but it wasn't nearly as bad as the XP-120. As for noise the Tuniq comes with a fan controller than can be fitted at the rear of the case. So you can set the fan level to what you are comfortable with.
Fixed it.
Tunnel, How did you fix it?
I am having same problem with speed going up and down. I don't see anything about speed stepping, C1 or C1E.

C1E under "CPU Settings" in BIOS. I turned mine back on last night - why not? ;)
:cool:
TY Randy
It was under "Advanced Bios setting" on gigabyte board.
Running at full speed now. wooohooooo!!!!!!!
Its stupid really they should set it to run at full speed. Then have the option to turn it on speed step.
Mine was running at 2.82 Ghz but had to send back the bad corsair memory that i received. should have my rig up and running hopefully by next week.
I got the same CPU and have started doing some OC today. I don't know what you mean with that C1E thing?
In CPU Configuration mine says C1E Support - [Enabled] should I leave it as that? (I have turned Speed Step off). What I also wonder is that why my programs, (CPU-Z, AI Suite) only says 0275,0x0.6 ~ 1649 but under load it is like 2400 MHz as it should, how come? (Sorry, I'm quite a noob).
EDIT: Think I solved my own problem by disabling it. :P

Just for comparison tunnel, my e6600 does 3.2ghz at stock voltage. Running at 2.82 is probably way under what yours can do. And, I believe you don't really start putting more stress on your PSU until you start adding voltage.
Guys, how come I can't change my FSB to over 280 on my P5B-E Plus on my E6600? Well, technically I CAN, but when I've gotten into Windows AI Suite and CPU-Z show that it has changed to the default setting 266 again :/. I'm having no problem with setting the FSB to anything in between 266 and 280 though. Any thoughts on this?

yer i know i could probably push it further but i am using stock cooler.
So cooling will be **** and if i go any more over 3.2 GHz temps will rocket.
I just asked my mate if i should try 3 GHz he said no because i only have a 480W PSU and it might burn the PSU out.
C2D's are not power hungry. A robust 480w PS is plenty for overclocking it.
