Hi all, this is my first ever forum so apologies if I make some noob errors.
Talking of noobs, I am that too which is the purpose of this post.
I cannot for love nor money get my E6600 any higher than 2.5GHz (285MHz x 9.0 Cpu multiplier) on nTune.
Trouble is I have no idea where to start. I have had some verbal training from DIY friends. Here's my nTune settings after a 3hour tune:

FSB - 285MHz x 9.0 - CPU core Freq 2,565
QDR - 1,140
DDR2 - 1,140
SPP - 3,000
MCP - 3,200
Vcore - 1.344v
Vram - 2.22v
Mem timings 2-4-3-13
If you need more info I can try to give it.

My system is as follows:
E6600 2.4GHz
Inno3D 680i SLI Mobo
2x2GB PC-8500 DDR2 Corsair Dominator + Airflow fan
Zalman CNPS9500 CPU fan
Coolermaster 850w PSU
Single Asus 8800GTX G80
& a Antec P180
Im running windows XP

Basically I have seen many internet claims that on the standard air cooler people are getting 3GHz from the E6600 but all I get at 2.7GHz is either a blue screen or freeze.
Apparently my CPU, Mobo & RAM are all upto the job.......... but unfortunately, i am not!!!
Again I am a complete noob to this so if anyone can explain bullet point by bullet point how to get more from my processor I would be very very grateful.

If I need to do it in the BIOS, I am willing if someone has again very simple terms to explain ;o)


Many thanks in advance
 
Hallow, welcome to the forums..

On to your problem, it looks like you've set the ram timings too tight, try reducing them to 4 4 4 13 and then trying again.
 
I had a E6600 that did 3.8Ghz and was a beauty. First off, do it properly using the bios. Forget using any software to overclock. Your ram timings are far too tight. The correct timings for your ram are 5-5-5-15 @2.2v. It's also running faster than it's rated speed. As you increase the fsb you also increase the speed of the ram. You need to change the ram speed by using the dividers in the bios. Don't be afraid to give that cpu more than 1.4v, just keep an eye on temps. It's a 65nm cpu and will take 1.5v if cooled properly.

Start off gently and try 9x333 (3Ghz) which should be ok with stock vcore or just a small increase. Adjust the ram timings to tha ones i stated above and the speed to the closest you can get to 1066mhz. At this stage it does'nt matter if it's less than 1066mhz. You should'nt need to increase NB voltage either. Do a stress test such as Prime or IBT and test for stability while keeping an eye on temps. Let us know how you get on.
 
Hi Locke,
Ok the timings were set by nTune, by its 3hr tune up facility.
Infact, all of the above settings were & they work fine & very stable however, they are only giving me a 2.5GHz CPU, about 5% increase from the 2.4GHz stock.
So are you saying that by changing the RAM timings to your suggested 4-4-4-12 I will be able to up the FSB to the required 333Mhz x 9.0 Multiplier to give me 3GHz ?
I still think voltages come into it somehow???
 
Cheers pastymuncher,
At work so I’ll have ago tonight & let you know.
Quick question, can I not increase the DDR2 & QDR to 1,333MHz? Why will I only go to 1066MHz? I read somewhere the memory I have can be OC to this - Sorry if I am talking nTune language again as I’m not that up to speed with BIOS yet.

Click to expand...

I very much doubt if your ram will run at 1333mhz. I had the same kit and it would only do 1142mhz. Anyway, it's best to get the cpu stable first and then play with the ram.
 
Ok all,
I’m really not having much luck here.
When I try to go past 285 (albeit on nTune only) my system crashes…... but that’s only 2.56GHz. Surely there must be something I’m doing wrong (I know I shouldn’t be using nTune before we start that discussion again)

3GHz with my set up! Surely that’s achievable.

I am going to venture in to the BIOS but before I do I would like someone to actually bullet point exactly what I need to change in order to achieve this.

What voltages?
Whether I should have my memory SLI’d or not? If yes should I use the ‘CPUOC 0% > 5% or max’ choices
Should the ‘FSB- Memory Clock Mode’ be ‘Linked’ ‘Unlinked’ or on ‘Auto’
‘QDR’ & ‘DDR2’ settings
Best FSB & Multiplier combination?
Best RAM timings?

I’m sorry to be so blunt but this is driving me mad. Someone must have a similar set-up to me & therefore know what to put in.
I know what works for one does not always crossover but it’s a ballpark scenario & I’m not in it ;o)

To be honest I would be happy with settings to get me to 2.9GHz
Any help on this would be greatly appreciated
PS Remember my first thread……. I am noob to this
PPS So please no comments about you shouldn’t be in the BIOS then ;o)
