E6600 OC

[dokko]

Hi people.

E6600
Gigabyte P35c DS3R
Noctua NH-U12P
GeiL 4GB DDR2 (2x2GB)

Got a E6600 running nicely @ 3.2 400x8, at stock volts, totally rock solid stable in Prime etc...with idle temps at 27c and full load 41c.

This makes me think there's room for some improvement. I've boosted the FSB by 10 (410x8 = 3280) the computer was fine loading up, ran prime and one of the cores failed, but i didn't change the stock voltage, would this be normal?

If so, what kind of clock & volt should i be aiming for?

I've no idea where to go on this as i've never ran anymore than stock volts through it, but with a new reliable fan i thought i might as well have a pop and see what it can do.

Would 3.6 pref 400x9 be optimistic? If not, what kind of volt should i be looking at for that.

I know every CPU is different, i'm just looking for ball park figures.

Many thanks

Steven.

I've used that setup (well almost had 2x1gb of the same ram)

380*9 (3.42) worked well with 1.425v and +0.3 on the ram and +0.1v on chipset
400*8 (3.2) optermal at 1.325v

Ram need some attention as may not run at listed speeds (reason I upgraded to a IP35 pro)

450*8 (3.6) was possable but needed over 1.5v and need extra MosFet cooling (as this board has no heatsinks)

never really streached this board as the Rev1 needed you to removed all the power cables prior to a CMOS clear - what a drag

good thread here

Clocking
1. Make sure that you have the latest chipset drivers and flash the board to the most recent bios version
2. On the main bios screen press Ctrl+F1 to open the advanced options within the menus
3. In the Advanced Bios Features Menu, Disable all of the following: CPU Enhanced Halt (C1E), CPU Thermal Monitor 2(TM2), CPU EIST Function
4. In the PC Health Status menu, set the FAN Speed Control Method to "Legacy" & FAN Speed Control Mode to "PWM" to maintain highest speed
5. Go into the MB Intelligent Tweaker (MIT) menu at the bottom of the page, set the System voltage control to "Manual"
6. These boards have a default VDIMM of 1.8v, set the VDIMM to co-ordinate with your ram. The Geil I have is specced as 2.1v so I have mine set to +0.3v
7. Set the MCH Voltage to +0.1v
8. Set the FSB Voltage to +0.1v
9. Set the VCORE to 1.45v - Please be aware that this will increase temps!
10. Set the CPU Host Clock Control to "Enable"
11. Set the System Memory Multiplier to "2x"
12. You're set to go, just increase the System bus Frequency to Overclock
13. I would reccommend that you use Intels TAT to monitor temps

Thanks mate.

I reckon i've got most of those 13 steps, from that thread previously, i'd forgotten about it, so thanks for that.

Do you think i should whack it straight up to 1.45v and try for a 3.4 - 3.5?

Edit: Wha'ts mosfet?

Google will tell you what it does - here's where it is on this board.
Many of the preimum boards have heatsinks on here - at stock the board doesn't need them but at +400fsb it helps stability especially in a low airflow case.

1.45v upped my temps but board didn't have a problem with it

Right cheers, i take there is no way to measure temps for these? Just either toasty or not toasty?

thermometer or finger (just above)
Ram heatsinks work fine, as does a fan in this area, or reuse a old sink from your bit box - use a thermal pad not tim as uneven surface

Haha, good old finger testing!

This might sound daft but would a ear thermometer do? It was designed so you could test babies milk as well as their internal temps, so surely it can work on that as well?

Thanks for the tips as well.

yes but I don't think they go above 50c (just a guess) as your child will be dead at ~42c
normally ear temp for a child is between 36-38c (I know I'm off topic but - 'every day's a school day')
