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 :)

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 =)

Q6600 B3
2.7Ghz
1.15v Bios
1.11v Idle

Will drop as low as 1.09 under full load. 100% stable as far as ive been bothered to push it.

Get a Noctua/Thermalright/Scythe cooler. May be difficult and expensive where u are tho.

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

^No. There's 20. 10 for performance and 10 for silence. ;)
If you look closely you'll see 5 NEW and 5 OLD per side.

More is rarely less and in this case the XIGMATEK comes cheap, SUNBEAM is not sold here (for some funny "green" directive banned gas in their heatpipes).

5OLD:5NEW could be but a coincidence but it's not really an important detail I think. What I was trying to say is it's better to have a wider selection. :)
I never really payed attention to the OLD/NEW stickers as shops here tend not to have the widest of selections anyway.
I was quite happy to get the TRUE + SFF21F and the HDT-S1283 in local shops ... but payed through the roof for the TRUE. :)

What's your RAM ratio?
Make sure it's unlinked or 1:1.
Then try 333MHz FSB / 1333MHz QP

You'll likely have to raise the Vcore to around 1.20V for 3.0GHz.

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 :)

6. Update EZ-Flash version to B319
7. Finetune H/W Monitor Voltage warning range
8. Fixed system hang when Music Alarm play length is over 1 hour
9. Lock 'F8' and 'DEL' function key when after entered EZFlash
10. Fixed Music Alarm auto shutdown when using Presler 3.4GHz CPU with WD1200 HDD and ASUS DRW1612BL

12. Fix system will report error when there is Legacy floppy is disabled at the same time when SATA ODD is the only device connected to this motherboard
13. Enhance HDD compatibility
14. Change Max FSB to 650MHz on AI-Booster
15. Fixed CPR fail when overclock too much
16. Finetune USB driving
17. Fixed power Fan can't work after S3
18. Set DDR2 Termination Max default Votlage to 1.25V (Memory Voltage is 2.5V)
19. Add patch to support Creative X-FI sound Card
