Hi guys

I'm pretty novice at over overclocking but I've just put together a relatively old system with the intention of overclocking the cpu and just after a wee bit help from you knowledgeable people!

I have:

P5K Premium board
Q6600 G0 SLACR
3 x 2gb DDR2 800 (2 from crucial & 1 pny) - timing & voltage specs are not on the sticks

My goal was to hit 3.4ghz and I have, just! I only managed it with Vcore set to 1.5125 in bios. in cpu-z it reads at 1.488v. Intel's specs for the chip are a max Vcore of 1.5v so I'm just about at that. Is there anything I can do to get this voltage down and keep it at 3.4? Temps are fine (low 60's under load).

Thanks in advance for any advice!

Hi first I would say take out the pny stick to get your dual channel memory performance back. turn fsb termination voltage up to 1.3v and see how far you can go up from there. what vid is your chip? look in core temp program. 1.5vcore seems a little high for 3.4.
 
With LGA overclocking you often have to deal with FSB holes also so it might be impossible to get completely stable on certain frequencies but just above and just below are stable fine.

Also on older boards they may struggle to supply enough/enough clean amperage for a Q6600 with clocks past about 3-3.2GHz. You will also find it a lot harder on your typical LGA775 board to get stable on higher clocks with more than 2 RAM slots populated due to the extra strain on the northbridge.

Not that I'd guarantee anything but I ran several E6600 and Q6600 on upto 1.536 on air and 1.6 on watercooling for 2+ years without any signs of any issues in that time and they are all working fine to this day - most at stock now as upgrades on older friends/family PCs. (If you can't afford to replace the CPU though I'd stick to 1.45 max as IIRC anything above there was in the zone intel label as "may cause permanent damage to your CPU").

Ok, first thanks for your response!

VID (idle): 1.1625v
VID (load): 1.3250v

I have removed the pny RAM and set FSB Termination Voltage to 1.3v as suggested. Unfortunately it didn't make a difference. I reduced the Vcore to 1.5v and it only lasted about 20 secs running prime.

I wasn't happy keeping the voltage that high so am now running at 8 x 400 for a clock of 3.2ghz. CPU Voltage at 1.4250v. Changed the FSB Strap to North Bridge to 400mhz.

Have left everything else as it was.

Might just have to settle for that. Still think Vcore is high for 3.2ghz though :confused:

Thanks again for your input

Yeah, miles too high, mine would happily do 3.6GHz on 1.3v.

What cooler do you have and what are your temps like?

You need both a good clocker/VID and a good board (mostly P45 based) for clocking to get 3.6GHz on 1.3v - a lot of boards just can't get them stable without pushing a lot more voltage due to the boards not really being designed for high clocked 65nm quad cores.

Also if its not a q6600 with the g0 slacr stepping your very unlikely to get 3.6GHz @ 1.3v regardless (Though seems the OPs is).

P5K Premium is p35 chipset. I thought it would have been decent for overclocking?

The chip is G0 SLACR

It was OK but the best board I found for overclocking for P35 chipset was the Gigabyte P35 DQ6. Better than the Abit P35 and Asus P5K. Now if you'd have got the P5Q then that would have been better. Still 3.4Ghz is a decent overclock and if your chip needs 1.5 on that board then that what is. For reference my needed 1.45v for 3.6Ghz. Most G0's would top out between 3.4-3.6Ghz.
 
Much better than my DFI Infinity 975x/g motherboard. That topped at 3 GHz with a Q6600 G0. Won't go any higher.
