Hi guys,
About a year ago I finally took the dive into overclocking and started modestly by pushing my E6600 to 3GHz. Now I'm feeling a bit braver and wanted to try to go that little extra.

My E6600 wasn't very tolerant from the outset and I had to notch the vcore upto 1.35 to get it to 3GHz. I recently purchased some new RAM however (in my sig... Reaper PC2-9200) and thought it would give more flexability during overclocking.
My Computer (as seen in sig):
Gigabyte DS3 revison 1 motherboard
E6600 2.4GHz OC'ed at 3GHz
OCZ Reaper PC2-9200 4GB DDR2 RAM
Running Windows 7 x64

I've uploaded images of my BIOS, hope that is okay, I thought it would make it easier to 'analyse'. Let me know if they need to be removed or if it would be more convenient to just copy the information into here.

I'm currently hitting ~55c in small FFTss CPU test, considering I'm using TT Big Typhoon and I recently applied some new Arctic Silver thermal paste I thought this was quite high.

Anyhow, I wanted to squeeze some more power out of my processor and I upped the FSB to 350, I increased the vcore by one notch, added +0.1 overV onto the FSB and left the rest as normal.
I restarted the computer, ran super-pi-mod and it did every calculation fine. I then stress tested my new overclock with orthos Small FFT once again but recieved this error:
Test 1: 800000 Licas Lehmer iterations of M172031 using 8k FFT length
FATAL ERROR: rounding was 0.5, expected less than 0.4
Hardware Failure detected, consult stress.txt file.
Torture Test ran 0 minutes 1 seconds - 1 error, 0 warnings.
execution halted.

I'm not sure where to go from here, I still know very little about overclocking, getting this processor to 3GHz was almost automatic, I just followed a few simple 'newbie' guides and upped the vcore when my tests failed
I thought my new RAM would perhaps make things a bit smoother but seeing as the timings are different to my last set of RAM (the old ones were 4-4-4-12 by default) I don't know where to go from here, if the RAM has anything to do with it at all.
I'd really appreciate some help and a few nudges in the right direction, would love to breach the 3GHz mark and perhaps touch on 3.2.

Unless... I would gain more by reducing the multiplier to 8 and increasing the fsb to maintain 3GHz to gain more power per clock but even then I would have to essentially do the same overclock as I wish to do now.

I would appreciate any help or advice you OC wizards can offer :)
i'm still not sure if I have un-optimised settings after all this time.
Thanks in advance,
Regards,
Tig
 
I'm no overclocking wizard but I've got my E6600 at 3.4ghz. FSB set to 380, V core to 1.4 in bios. However, my board has quite low v droop so v core shows 1.392 in cpu-z.

Set your rmemory to it's rated timings and voltage (probably 2.1 but please check 1st!) and make sure that the overclock does not force it above it's rated speed.

Then try setting your vcore to 1.4v and go for 3.2ghz. (356 fsb).
 
With a good cooler you can go way above 1.35 on air with only minimal risk - general rule of thumb is to keep it under 1.5 - tho I had a E6600 @ 3.825 with watercooling and 1.65 vcore running 24x7 for ~2 years no hassle and its working fine at stock in my media PC now.

Once you get over 3.2gig tho the voltage required for each extra 50Mhz can be a massive increase...

Thanks guys, I've been doing some reading myself and I see that if I don't want to be too ambitious I'm settling for one of two options:
  1. overclock to 3.2GHz
  2. reduce multiplier to 8 and set fsb to ~375 to match 3GHz

If I'm correct...
8 * 375mhz = 3GHz is faster clock for clock than
9 * 334mhz = 3GHz
Is that right?
And if so, how much of an improvement would that give? Would I still do better to go for the first option (overclock to 3.2)?

On another note:
I was unhappy with the vcore having to be put up so many notches just to reach 3GHz and also displeased by the temps so I tried reducing the vcore a few notches hoping that my new RAM would aid my plight. I ran orthos for 30mins and it was fine, not running much cooler though. I'll run orthos over night though just to be sure.

I'll try your suggestions tomorrow in order to get to 3.2GHz anyway, so long as 1.4v is safe.

I run mine with about 1.4 vcore for 3.4Ghz. Can get it higher to ~3.6 but you really have up the juice. I use 9 x 378 if that helps, been running this chip for 2.5 years, amazing piece me kit, still running anything i throw at it.
 
I had the same mobo/cpu combo as you and could only get to 3gig at 1.45v bios.
the board isn't the best at getting a high oc but keep plugging away, yu may be able to get it higher.
