That was under load.
Idle is 1,200v:

Gotta love the voltage damper thingy of the P5K Premium.

Im building a new computer, below are the parts I have so far.
Id like to Overclock to about 3.1 -3.2Ghz on Air.

What settings do I need to make in the BIOS to achieve 3.1-3.2Ghz?
Also, please include memory settings.

Thank you,
Novak

Zalman 9500..... you won't get very far.

try:
1.4 Vcore to start with
355 FSB
1:1 memory for now

and then lower your Vcore until it's at lowest stable voltage. then up your memory divider to something lower than 1:1.5 (try 1:1.5, Ballistix are said to be very overclockable)

Hey,

does anyone know ifthe asus p5w dh deluxe motherboard overclock as well as the asus they used in this article?

im considering getting one of these mobos, but only if they can overclock well....

Woodstock 9th December 2007, 09:58

p5w dh is very outdated, your best bet is something p35 based

hi there,

After reading the articles, i decided to OC my q6600. However, i didn't quite reach the 3.2 ghz mark... ,hell.. i even struggled to have a stable system @ 2.9ghz.. I changed the FSB, vCore voltage, nforce SPP, MCP voltage just like the articles said...

My machine got blue screen while booting windows when i tried 1451 FSB(qdr) --> 362*9 frequency
then i lower my FSB to 333*9, i could load into windows fine. But when i tried some games (tf2, crysis), the games loaded up, and then blue screen came within minutes of game play.
I got a somewhat stable system @ 325*9 --> 2.9 ghz frequency machine.. (it got blue screen and reboot twice as well, but it seems fine for now..)
I checked the temperature with coretemp, its 38-43C from core0-core3, so its not that my cpu is too hot....
here are my spec..

q6600 G0 with Coolmaster Hyper TX cooler+heatsink
Corsair Twin 2 x 2048-6400CA 1G/800/DDR2
8800GT (no OC)
Inno3d 680 SLI mobo
PSU is a 750 W.. (forgot the brand, but its one of the better one.. $$ wise)

cpu core : 1.4625
cpu fsb: 1.4v
memory: 2.250V
nforce SPP : 1.45V
nforce MCP 1.550v
Ht nforce spp <=> Mcp : 1.40V

So if I increase the vCore, would i be able to get a stable system @ 3ghz or more? The article said a safe maximum vcore for aircooled chip is 1.4625 though...

Many thanks if anyone can help me out..

Kosh 17th January 2008, 05:31

Hey all. Not only new to the site but new to the game of beyond retail tech specs as well. I used CPU-Z and found out that even though I bought the processor this January I got a B3 stepping.

Does this mean I'm screwed in terms of overclocking it to better performance? I'm not rich so I can't afford to buy another if it bursts into flames on me so I don't want to try to go insane, but everyone else is raving about the G0 and I kind of feel like the kid at school with last years cool lunchbox.

Thoughts?

[USRF]Obiwan 17th January 2008, 08:25

Why dont you try? Even if you have the most useful Q6, without some other good hardware and cooling you can clock all that you want, but its still a nogo.

Bindibadgi 17th January 2008, 09:02

Kosh - the processor we overclocked in this article was a B3 and we still got in-excess of 3GHz out of it! :)

Hi, you've got plenty of everything there - you could either simply be unlucky or your BIOS is out of date. On boot - the characters at the top should tell you which version it is - P-something. The latest from Inno3D is P30 and you can upgrade in the NV control panel in windows. :)

Kosh 17th January 2008, 20:25

Ok so my first go was to emulate what you all did, seeing as how I have no empirical experience doing stuff like this and this is the result that I have been running for the past day. Any feedback is as always greatly appreciated, even if its to tell me to stop being idiotic. :)

Kentsfield Intel Core 2 Quad Q6600 B3 Stepping @ 2.4

As for my RAM, I am running 2x2Gig sticks of Patriot DDR2-800 that doesn't seem to want to run at its normal 2.0v 5-5-5-12 under this load, so under AUTO timing in the BIOS its set itself to DDR2-745 5-5-5-10

Don't know exactly what that imples. <laughs>

Thanks again mates.
Kosh

Kosh 17th January 2008, 22:11

EDIT: Ok so I read about Prime95 and ran it on my current, above, overclocked settings for 5 hours. The Max CPU temp was 55c with the average being 48c and the Motherboard temperature was 30c until hour 1, then 31c at hour 2.5 it was 32c and it peaked at hour 5 with 36c.

Good? Bad? Ugly?

perplekks45 18th January 2008, 21:56

There are not few people saying everything less than 24 hours of Prime95 (or better Orthos)... maybe they're right.
I never ran any stress test longer than 12 hours and I never had too many issues to be happy with my system. Temps seem okay too even though 55°C max might be a bit on the high side. It's air, isn't it?

Kosh 18th January 2008, 22:35

Yeah, 3 case fans and then a Artic 7 that was recommended to me by someone probably my tech better.

I guess I'm a bit mystified on the temp issues. I've read that this chip or that chip is rated to a certain max range, and the same with some motherboards, but I have no clue what this means in practicality. Some people have told me that operating at load like 55c will take 8 years off the life of the proc, but I have no clue how long they're rated for anyway.

I also have people tell me that overclocking isn't worth it period because of the gains vs hardware damage, but like I've said countless times...

I'm an infant at this.

Five hours is fine - you have a great overclock there ;)

Don't listen to the BS people go on about "processor deaths" - I've never known a processor to die and I've never known someone to keep a CPU overclocked more than a couple of years. Usually post-life in a main system they'll do some menial task elsewhere at stock.

55C is absolutely fine, don't stress about it.

i only tested for an our with prime 95. maybe an hour, my system is stable. never crashes. running 3.0ghz with a b3 stepping, not the g0. Thermaltake maxorb cooler helps with the temps. antec 900 takes care of the rest.

Kosh 19th January 2008, 06:52

So, new issue.

Prime95 hasn't failed, the temps seem ok but everytime I go and play COD4 for about an hour my machine just shuts off and reboots.

I can play World in Conflict without this happening, so is that an application thing? I'm guessing not since the actual machine reboots.

Do I need to lower the OC? Or?

Thanks,
K

chrisb2e9 19th January 2008, 18:35

sorry for not reading the thread, but have you tested the ram?

Kosh 20th January 2008, 04:31

Well I can't say I know how to test the RAM per say but sure I /can/ if I know how.

Oddly enough this seems to be an issue ONLY with Call of Duty 4. Crysis, World in Conflict, Supreme Commander or any other slew of games work fine under the OC but COD4 just shuts the computer down.

Thoughts?

Shielder 21st January 2008, 10:22

RAM testing is easily performed using Memtest. It does a thorough test of memory (and stresses the CPU a little too) and will run through a series of tests to see if there are any errors. Let it loop for about 2-3 hours (even better is overnight) and see whether there are any errors.

Oh, yes, the DDR 745 speed you referred to above will be due to the RAM running in sync with your 371MHz FSB speed. When I get my Q6600, if I get that sort of OC I'll be well happy!

I'd drop down the OC a bit and then see if your system is still crashing out.

Any comments on a ASUS P5N32-E 680i / Q6600 OC combo? That mobo is one I've been eyeing up for awile. Also, how well would a AC 7 pro handle the quad OC?

This will really be my "first" build. At least where I have bought parts specificly for a new PC.

Thanks for having compassion on the noob! :D

I don't know if anyone answered you yet, but I have the combo that you suggested above with a Q6600, I reached 3Ghz without a problem no voltage increases at all, I just unlinked my ram and pushed the FSB up, I have not tried going higher than that because 3Ghz is overkill already, and it run like a dream.

Hi, also dunno if you got a reply, I use a combo with the Asus P5NE32-E SLI with
Q6600 G0 CPU @3150mhz and 1400mhz FSB.
Link to pic with temp, voltage and clock settings, please note that the voltages shown are those that have been set in the bios manualy, under the overvoltage section.

atomicvai 7th February 2008, 14:57

I've found that 3.15ghz spot to be the perfect speed for my combo. This is with all stock voltages, runs 24/7.

Asus P5W-DH (Added active cooling to NB and SB) Antec P-182 Case
Q6600 @ 3.15ghz (350x9) Scythe Ninja Rev B (50 deg max load)
2x2gb OCZ PC6400 @ 875mhz (I think thats the number, I'm at work) 5-5-5-12
GT8800 with HR03GT @ 750/1900/950 (48 deg max load)
2 x 250gb WD SATA RAID 0
Enermax Noisetaker II - 600W

As soon as I start to push past that though, even upping voltages etc I can't seem to get anything stable. I had an e6600 on it before and could hit 3.6ghz (400x9, hot but stable with upped voltages), so I'm guessing this processor just doesn't want to go any faster. Maybe it's a motherboard limitation? Who knows. I've thought about upgrading the board to a P35 or X38, but I just don't know if that would really make a difference. Any thoughts? Also, what's peoples thoughts on pushing ram past its recommended voltage (mine is 2.2v thinking of trying 2.3 or 2.4 to get to 933mhz)?

TheJerk 20th February 2008, 14:45

Hi all!

Both new to OC and new to the fantastic well of knowledge this forum turned out to be!

I am new to OC and I would be extremely grateful to get just a few simple "no problem" or "hell no, don't" on the following plan.

Getting my new rig in a week or two, this is what it looks like:

-Corsair Powersupply 750W Black,ATX/EPS,140mm Fan, 8xSATA, SLI
-Asus P5E, X38, Socket-775, DDR2, ATX,Firewire, GbLAN, 2xPCI-Ex(2.0)x16
-Q6600
-Asetek LCLC BU 1CPU Liquid Cooling,Sealed 12V.
-Corsair TWIN2X 6400 DDR2, 4096MB CL5, Kit w/two matched CM2X2048-6400 Dimm's

Seeing as most ppl seem to run into trouble either with cooling or mobo-issues, this should be a good setup for OC I thought.

Ok, the question: leaving multiplier and ram settings alone, upping volts by 10 or 15%, where would I aim the FSB?

If I am not mistaken, FSB=350 gives 3,15Ghz. 400 would give roughly 3,8 GHz. What will the setup take without additional bridge-cooling? Anyone out there with experience of clocking this CPU on that mobo?

Thanks!
