what's the Lowest CPU voltage possible for Q6600?

hey guys, i need some help please.

i live in Africa, where the ambient temperature is a bit high... sooo cooling is important for me, since i just have a stock cooler from intel for now and the temps are a bit high (60-70 idle) i would like to know what's the lowest CPU voltage i can put on my processor so it gets cooler...

my pc consists of :

Motherboard - Asus P5N32-E SLI PLUS
CPU - Core 2 Quad Q6600 @ Stock
Graphics card - Nvidia Geforce 8800GTX @ Stock
RAM - 2 GB RAM (Legend i think, not very impressive)
HDD - 400GB HDD Seagate Barracuda 7200.10
power supply - Procase 550W

the VID is 1.2750v and i lowered in the bios to 1.17v and the temperatures dropped to 50-52-50-49 idle (using coretemp )

how much lower can i get?

i appreciate the help

tks in advance

i just lowered the voltage do 1.05 and when i ran prime95 it restarted... so i put 1.10v and its stable... with idle temps at 47-49-47-45C =) and load around 68-68-73-66 C, =/...

is there any other voltages that i can lower to make my cpu cooler? or anything else i can do?

the reason i dont use an aftermarket cooler is because they don't sell them here im Mozambique... i need to go to south africa maybe to buy one

any other tips on lowering my cpu temp?

i have an AC at 22C, case is opened ...

tks

Make sure the cooler is seated well too, if it's not, no amount of undervolting will make it run that cool.

i checked and the cooler is properly mounted... one thing to mention is that i don't have a good after market thermal paste. the one i`m using is a white crappy thermal paste =P...

any ideas on how to get the cpu temp lower?


tks =)

My Q6600 G0 runs stock 2.4GHz at 1.075V (BIOS) 24/7 Prime95 stable on a noname LC Power 550W (green power) PSU. I mention the PSU because it ran 3.0GHz at 1.24375V (BIOS) on that PSU and now runs 3.0GHz at 1.22500V (BIOS) on a Corsair HX 620W. I haven't tried lower voltages at stock but it could go a notch or two lower I guess.

I posted in graysky's thread sometime in November 2007 (while running stability tests) asking if this was "normal" for a VID = 1.30000V chip.

Temperatures are around 40C at load (24h Prime95, 4 threads).

witch is the best Air cooler for the Q6600? i want to know the BEST OF THE BEST... so i can get the lowest temperature ... i don't really mind the noise.. just as long as i have the desired cooling.

tks

There's 10 heatsinks in a top 5 list

I think the 5 new and 5 old thing is a coincidence.

Anyways, Xigmatek ftw. Not the push pins though.

I prefer to pay nothing but maybe that's just me.

tks guys... for everything =)

i'm now running @ 2.678GHz @1.15v... my system seems fine.. but when i run prime95 for hours... its restarts... but just when its for a loooooong time....
any ideas?? and i cant get pass 1190 on the rated FSB , when i put 1195 its start's windows... but with prim95 it crashes, if i put 1200 it doesnt even go to windows... =(... what can i do?

i appreciate your help...

and tks for the site =) i just need to figure out where to buy the sunbeamtech=P

the memory is already unlinked... and i put 1.270v for 1333 and it just wont go.... ahhhh... my bios version is 1003... is that a good bios version? maybe that's the problem

it was a 0302, but i could not do anything with it, so i upgraded it to 1003

what do you think about this version:

Version 0805 2007/08/27 update
Description P5N32-E SLI Plus BIOS version 0805
1. Enhance CPU overclock capability of FSB1333 processors
2. Add new CPU uCode to support new processors
3. Enhance memory compatibility
4. Enhance overclocking capability
5. Enable support for ASUS SK-2690 keyboard
6. Enable support for Razer Copperhead USB Mouse

is it good?

if soo ill load that one instead, but my only concern is that there are some bios versions that are faulty =S..

really appreciate your help... tks

the memory is already unlinked... and which is best, unlinked or 1:1?

i think that maybe it's the MOBO bios version it was originally 0302 and i upgraded it to:
Version 1003 2008/05/13 update
Description P5N32-E SLI Plus BIOS 1003.
1. Fix LAN fails after resuming from S3 mode.
2. Enhance compatibility with certain add-on Raid card.

but theres another one that i want to know if its better:

Version 0805 2007/08/27 update

thanks =)

...... sorry for the 3 posts =S...i thought that they didn't enter the forum so i posted 3 times...sorry

tks... ill try it out tomorrow afternoon =)... ill keep you updated...

i appreciate it a lot

Nothing really.
I'd ask you to show me a screenshot of CPU-Z/HWMonitor/CoreTemp at the highest stable frequency (idle and load) but I'm really out of ideas.
You could try
300MHz : 2.7GHz @ 1.3V
311MHz : 2.8GHz @ 1.3V
322MHz : 2.9GHz @ 1.3V
And see what's still stable. Maybe it just needs more voltage.
I would stay under 1.4 but that's just me.
