Q6600 + P35-DQ6 Help (Newb)

cyid · Sep 20, 2007

Ok, I am a OC nubblet. I decided to post here because of all the posts I have read where people are actually helping and answering questions, not flaming.

So, let me start off by saying I have read the guides stickied and I have tried the search, but I couldnt find anything that I needed.

I am trying to over clock my system to 400FSB (I may or may not be able to with my cooling). But I cant even get my system to 300 FSB. It is very unstable. I am not sure if I am doing something wrong, or missing something, or what. So, I was hoping someone might be able to step a first-timer through the process.

First, here is what I have done.

I have set my RAM timing to 5-5-5-15 (as was suggested in a guide.. he said to start there and get the CPU to where you wanted it, then try lowering the timings if you want.)

I then set my voltage to 1.36.. the max for my CPU is rated at 1.37. I also read that I am supposed to start high, find a stable FSB + Multiplier and then work the voltage down as far as possible while staying stable.

I then changed my FSB to 400, 333, 300 and I couldnt get it to POST. So then I tried it with a lower multiplier. No POST. So then I started to work up slowly. Why rush, right? I set the memory setting to Auto, set my CPU voltage to Auto, then I started at 270 FSB .. my board has it at 266 x9. I was able to get to 285, and then around 290 it started to crash. So, I have it at 285 right now and it is not crashing windows or anything. I have not stress tested it like I should, but I kind of wanted to get higher before testing the system for hours.

I also noticed that my BIOS used a voltage of 1.40 on Auto. So I went in and changed it to 1.10 and my system booted fine.

Any help would be great! Thanks for your time

My System Specs:
CPU: Q6600 G0
Stepping: G0
Core Speed: 2565.1 MHz
Multiplier: x 9.0
Bus Speed: 285 MHz
Rated FSB: 1140 MHz
Core Voltage: 1.088 V
Core Temps: 32C 32C 32C 32C

MB: GA-P35-DQ6
BIOS: F6

Memory: Corsair 4GB (2x2GB) DDR2 800 - PC2 6400
Frequency: 427.5 MHz
FSB

RAM: 2:3
CAS# Latency (tCL): 5.0 clocks
RAS# to CAS# Delay (tRCD): 6 clocks
RAS# Precharge (tRP): 6 clocks
Cycle Time (tRAS): 20 clocks
Command Rate (CR): 2T

That is the information I get from CPUz.

look at your Core VOltage:it says 1.088, but i thought u were just saying ur vcore was. do not have your vcore on auto, set it yourself. try 1.36 and see if it will boot at 2700mhz. If you want to get up higher you are going to have to up your voltage, because vdrop will drop it even lower. and by the way, when intel puts on its specifications that the highest is 1.37v, that just means that when you get your processor your voltage will be somewhere below that. It doesn't mean that you can't push it harder. Wait for someone else to post but i am guessing that it is your voltage. What is the voltage on your ram at? i am pretty sure its your vcore though man.

by the way,
WELCOME TO THE FORUM

Thanks! My Core Voltage was at 1.40 when it was set to Auto.. I noticed when I was making this post that it was that high, so I rebooted and went into my BIOS and changed it to 1.00, it crashed in windows during a stress test, so I upped it a bit to 1.10 in the bios and it says 1.088 in CPUz. I also tried having it at 1.37. I tried 300, 333 and 400 at that temp and couldnt get it to POST

GTengineer · Sep 20, 2007

first, do not set vcore to auto, and maybe I missed it but what cooling are you using? If you have some decent aftermarket cooling try the following....

set vcore to 1.45 (manually)
fix cpu multiplier to 9
set memory multiplier to 2 (this is equivalent to 1:1)
set FSB to 400MHz
set RAM voltage to +0.2V or +0.3V (which is equivalent to 2.0V or 2.1V respectively) - check what the manufacturer recommends.
set NB voltage at auto for now your board should be able to do 400MHz fine but if not then up bump it up +0.1V or +0.2V

if it boots into Windows then open coretemp and check your temps, also run Prime95 v25.3 and check what your load temp is. I would try to keep it below 70-75C but you'll find other who would argue....

download cpuz and report what your cpu voltage is when you get into Windows and under load while Prime stressing using small FFT option.

Most Q6600 G0 can do 3.6GHz around 1.4-1.45V (real) however due to vdroop you may have to increase it a bit higher in the BIOS.

Another OC 'nubblet' here as well....I have no advice for you on your system but just wanted to let you know that I read here regularly, post here occasionally, and have found these forums and BOTH the moderators and all of the posters to be extremely helpful. No flames here at all from what I have seen. Dont be shy about asking stuff (Im sure not!!!) because thats how we are going to learn.

Good luck on the system!

good suggestions. I would recommend NOT DOING 3.6 GHZ. I dont know what your cooling is and if it isn't good its gonna be way too hot. On a good cooling system i have seen the q6600 go to 3.3-3.4ghz. Just a suggestion. PLEASE STATE YOUR COOLING (heatsink, fans, water cooling, etc)

I am guessing it is your voltages, either your Ram or your VCORE (most likely your vcore) do what engineer recommended.

Good Luck!

Bold denotes air cooling 3.6GHz besides 1.45V will end up being something like 1.4V real voltage under load. Even if it somehow was actually running hot, simply booting into Windows and checking temps would not be a big deal. This is all assuming you have decent air cooling though if you are still on stock cooling then I would agree DO NOT follow my advise as I said: If you have some decent aftermarket cooling try the following....

cyid · Sep 20, 2007

Thanks guys! Quick responses! Loving it. I will go ahead and try GTengineer's advice out right now.

Oh, and I am sorry I left out my cooling. I am running a Thermalright Ultra 120 Extreme (With AS5) and I have a CM Stacker 830 Evo... Right now I do not have the best fan on my HS, and I only have 2 Fans in the case running (3 with HSF), but I will be getting more soon. Just got paid today. ;-)

Dawgdoc · Sep 20, 2007

Silly silly question here.....I hope you guys dont get tired of my ignorance.....

As seen in my sig, I have a Q6600 SLACR on order (just ordered today!!! :bday:

) and will likely be using a TR Ultra 120 extreme HS.

My silly question is as follows.......

I do not see that a fan is associated with this HS which everyone loves so much. Do you add a fan somehow on top of this? Is there a fan somewhere on it that I cant see?

Im a little bit confused if there is no fan.......

Thanks.

yeah comes with no fan you need to buy the fan additionally, can't help you there though hopefully someone else can recommend one.

Excellent, remember to keep an eye on your temps with coretemp and keep them below 70-75C (IMO).

cyid · Sep 20, 2007

I will be able to help you with a fan. Since I have that HS and I have looked up reviews on fans for it. I just need to find the information I have.. (Just formatted, everything is everywhere on another drive.. lol)

Temps are as follows (Not testing). 37 37 31 36 with SpeedFan (after teh 15C modifier).. I keep forgetting to disable driver signing for Core Temp.. going to test now

cyid · Sep 20, 2007

I get temps in the high 50s while testing. Once I got 61C.

Only problem, two of my tests errored out.. done the test twice now and same results.. Error before 30 seconds or so

GTengineer · Sep 20, 2007

Are these temps at 3.6GHz and settings I told you? Those temps are not bad at all!

what do you have your RAM and NB voltage set to?

cyid · Sep 20, 2007

Everything you told me, I did.

CPU is actually running at 1.408 while I type this. (I set it to 1.45)
RAM I boosted to 2.0, it was at 1.8. But now I check CPUz and it says it is still at 1.8.
And NB I left on Normal

cyid · Sep 20, 2007

I had 3 work threads error out.. then I stopped the test.

honestly I don't know why but cpuz always shows wrong voltage here so dont worry about cpuz when it comes to memory voltage.

If you are getting memory errors try upping the memory to 2.1V (+0.3V) or 2.2V (+0.4V). The package your memory came in should say what the manufacturer rated it for. Just set it to that.

BTW, that 1.4V (real) in cpuz is what mine does 3.6GHz too. These cpu's are very predictable.

are you running Prime with small FFT (cpu test)? or testing the RAM? I am confused what exactly you are testing cpu or RAM.
