Q6600 on GA-P35-DS3L overclocking problem

I've been having an issue getting my Q6600 up to 3.0 ghz stable. I've been poking around this forum, and the internet for a few days, but the best I've achieved so far is that it won't *immediately* shut down. It does shut down after my mobo splash screen comes up, however.

My system specs

Q6600 w/ Arctic Cooling Freezer 7 Pro
Gigabyte GA-P35-DS3L mobo
eVGA Nvidia 8800 GTS
2x2gb G.Skill DDR2 1066

I'm not completely new to overclocking, but this is my first time trying on a Core 2 machine. I've tried upping the cpu voltage, and then increasing the FSB slowly and incrementally, but it doesn't seem to work. Ram timings are set properly at 5-5-5-15, and as best I can tell there isn't anything that should be preventing it from working.

Anyone with any experience overclocking on a similar setup, I could really use some suggestions.

GUIDE: Overclocking On P35-DS3L

Quote:
Many users reports and my personal testing has shown that there is a very good chance you will run in to issues with RAM higher than DDR2 800, such as DDR2 1066. I recommend you get quality DDR2 800 RAM and run them at 1:1 ratio or overclock the RAM. This issue dose not apply to DDR2 800 RAM that has been overclocked.

I have this mobo, and my quad is overclocked to 3.2 gigs heres how i did it. In the bios, set the voltages to auto, and then kick up your muliplier, save and start. I run totally stable going this route. You only want to mess with your voltages if your having problems with v-droop and such, but you should be able to get 3.0 gigs or higher by going this way.

You can't raise the multiplier on this chip. 9 is the max. you can lower it, but that's all.

This is probably some kind of memory divider issue. hit CTRL+F1 in the main BIOS screen, that unlocks memory options. set the fsb to memory ratio to 1:1, that will underclock the ram and allow headroom for oc. Set the latencies to 5-5-5-15 manually. Now you can raise the FSB to overclock the CPU. 3.0 shouldn't require any voltage increase.

once you settle on a good CPU overclock, you may go back and begin messing with the memory bandwidth and latency timings.

Your thinking of the wrong multiplier, im talking about changing it from 9x266 to 9x333.

Going from 266 to 333 is changing the FSB, not the multiplier.
May 16, 2008 5:34:20 PM

Ahh, well im confuseded then, but hey, worked for me.
May 16, 2008 5:36:08 PM

After screwing around with it a bit more, I think it must be the ram. Tried 1:1, no boot. Even tried underclocking the stuff down to 667, no dice.

I'll probably just return the ram and pick up some DDR2 800, unless anyone has any more good suggestions.

Thanks, by the way, to everyone who has tried to help so far.

Dude i had the similar problem reaching 3. gigs with a g31 motherboard but i managed to do it ...fisrt u have to set the multiplier to 9 and the the FSB speed at 312 that gives u 2.808 GHz for now ... obviously reduce the time ram to 266 ... PCi-express 100 mhz...increase the voltage upto 1.48 and then in Vista and only in Windows Vista u have to use the EasyTune Utility provided in ur instalation Disc from Gigabyte ( Easy Tune 5.0 Pro if i remenber well) .... then use Cpu-z and u will see the voltage is running under voltage at 1.44 but stable...

Then execute Ntune at increase in little amonts the Fsb speed ( Overclocking Tab - Easy Mode ) first upto 2900 and then upto 333 * 9 = 2997 ...

Wait and dont run any program in the background neither open anything...

This program just works in Vista no Xp ....

I hope hs works 4 u

Ah, I'm running XP 64, not Vista. :( 
May 16, 2008 5:43:48 PM

Umm, yeah. xp 64 is about as bad as millenium edition in my humble opinion.

^Many people run XP x64, esp. ppl who work with CAD,etc. I agree there are driver issues and such but If you do your research right you can avoid driver problems and the like with XP x64.

NEVER OC THROUGH WINDOWS It's just asking for trouble.

@OP: Just try some DDR2 667/800.

Yeah, it's not stellar, but 32 bit XP won't recognize all 4gigs of my ram.
May 16, 2008 5:48:55 PM

Yeah, i just took the half a gig hit, and keep on truckin, but i guess im one of the few people whos o.s. actually recognizes most of the ram i have installed. And i totally agree with shadow, never oc through windows, plus gig sent a crap software to use for this purpose anyways, but stay away from it.
Incase your wondering both xp and vista with my system recognize 3.5 gigs, and with the hella low prices of ram these days, i decided i could live with half a gig being gone.

I have an EP35-DS3P, Q6600 cooled by a TRU120E, and 2 GB of Crucial RAM in an Antec 900 case running at 3.6 GHz. Prime95 runs 24 hours. Core temps go to 65C.

Getting started, I pretty much followed the P35 OC Guide.

Final settings were 9 X 400, System Memory Mult X2
DDR2 Over volt: + 0.4 (Crucial specs 2.2 volts)
MCH +0.100 volts
CPU voltage 1.45 volts (droops to 1.40 volts)

Pretty much the same settings for 3.3 GHz except
MCH +0.05 volts
CPU voltage 1.30 volts.

Prime95 kept failing at 8 to 12 hours before I bumped up the MCH voltage.

At 3.0 GHz, I did not need any CPU voltage increase.

May 16, 2008 7:38:10 PM

I'm running a q6600 on a p35ds3l also. Here's my settings if it helps.
(the VID on my cpu is 1.35 btw)

for 3.6 ghz:
400x9
Vcore=1.5v (droops to 1.46 idle, 1.425 loaded)
+.1v on FSB
+.1v on MCH
+.1v on RAM (running 2gb pc6400) timing@ 4-4-4-12
3.6 runs fairly stable for me, and temps at ~65 loaded with arctic freezer 7. It will fail on OCCT before an hour, but will run Prime95 for at least 8 hours for me.
note: i did lap the HSF and CPU
Also, I put a small fan on the NB because it was getting very hot. This solved the problem.

@3.4ghz
378x9
Vcore=1.425v
Ram +.1v
all other voltages at default.
This is what I run at 24/7. Haven't gone past 8 hours on prime95, but is plenty stable.

@3.2
9x356 or 8x400
Vcore= 1.375v
RAM +.1v
all other voltages stock (unless running 8x400, then FSB and MCH +.1v)
Running 8X400 gives a little better memory performance I think, but I also had to add voltage to FSB and MCH. Though I installed NB fans, I'm still leery of overheating them.

On all of the overclocks I'm running the Ram 1:1 (2.0 on the ram multiplier in the BIOS). And the RAM i'm using is 2gb of some low cost super talent stuff. Seems to run well though at 4-4-4-12 with .1v overvoltage. The temps I get with the Q6600@3.4ghz are ~35 ilde and ~60 loaded. The temps were much higher however before I lapped the cpu and HSF.

I've booted and run 3dmark05 with the CPU@ 3.8ghz, but It required a Vcore over 1.6v. Not to mention even more voltage to the FSB and MCH. I just wanted to see if I could do it though...obviously wouldn't think of running those settings for any length of time.

Obviously the Freezer Pro 7 isn't the best cooling option. I'm debating whether to install a water cooler in this rig, or to buy a non **** case that will fit a 120mm air cooler.

The two above posters are probably running DDR2 800 so they are able to OC. This shows that the motherboard is capable of being OCed.

HI guys, im having problem getting my Q6600 stable @ 3.2

Specs

P35-DS3L
Q6600 w/ Zalman 9500A
3.5 Gb-ram OCZ Reaper Edition
Sapphiere X1950GT 256mb

First time I tried it, it was stable for a day. Next day when trying to turn it on, i didn't get anything on the monitor, but the computer was running. I restarted the computer, and the Bios was set automatically back to 2.4. I only go stable running on 3.0. But can't get to 3.2

Any idea?...I don't know if the problem may be the 667/800? I can't get it to be even 800/800. While by running 3.0 i can get 667/667 even.

Thanks for the help guys!

1. Did you read the guide?

2. What temps were you getting on 3Ghz?

3. Are those Reapers DDR2 1066 version?

I Have the GA-P35-DS3L and an Intel core2duo E7300 and 2gb's of Kingston ValueRam DDR2-800mhz. I have this problem though..and changes to the multiplier in the bios leads to a system crash during xp start up. Even when adjusting the bios settings to make my cpu and mem run at stock speeds it still crashes. At first I had the problem with easy tune 5 asking me if i want to save the new cpu configuration as default during start up and before i could sellect yes, it crashes...I uninstalled easytune5 and still have this problem..If you have any advice or troubleshooting methods that would be much appreciated.

^What BIOS version?
February 24, 2009 3:34:58 AM

Funny enough I had the same thought, I had the f7 bios version so I updated to the new f9b (I know beta's aren't always safe) but it's working perfectly fine now. I got to 3.5Ghz on 8.5x412 and memory at a 1:1 ratio (2x). Anything above this fsb gave me the blue screen of death....Now I don't know if that's because the fsb has hit it's wall beacuse it's already at 412! over the 266 default..But i'll start playing with the voltage now and see if I can post at 3.6Ghz and i'll bump the mem up to bout 900mhz. Just for the record, The Kingston valueram modules I have use 6-6-6-18 timings at default and at over 900mhz they hold up very well but need a +0.1v increase for anywhere between 900mhz and 950mhz, haven't gotten them faster than 950mhz.
February 24, 2009 3:57:51 AM

Just a question, i have noticed a fsb voltage modifier in my bios, it has 4 options; [normal], [+0.1v], [+0.2v] and [+0.3v].
Would it maybe help getting the fsb higher if I increase the fsb voltage? If so what would be the best option?

^That may help, since you are pushing above 400Mhz. And yeah, I was going to tell you to use F9b or F8f. The F7 was a bit problematic with OCing and voltages.
February 24, 2009 1:15:03 PM

Would you possible know what voltage would be appropriate for 3.6Ghz? Im very hesitant with voltages since I have no idea where I should draw the line...

February 25, 2009 3:29:00 AM

I did, I pushed the voltage up to 1.35 and got a stable overclock. I maxed out at 4.05ghz. Memory then became a problem at anything higher than that. It was fun!! SuperPI @ 1M was 13.000s im pretty impressed. Thanks alot for your help. I'm going to get a aftermarket cooler and find a stable but not wild o.c for 24/7.
February 25, 2009 6:41:14 AM

i had the same problem and i actually lowered the voltage, lowered the multiplier and upgraded mhz i only had 7x multiplier and 425 mhz, got me almost 3ghz, closest i could get w/o ddr3 ram, DONT MESS WITH VOLTAGE, i had a bad experience. with my x38 i got up to 3.8 using 9x with 334 and uped my fsb to 1332 or something like that. still stock voltage stress test and everything

I spoke to one of the most experienced South African Overclockers, SETH, I attended one of our south african overclocking league finals and got some tips from our top guys. They basically told me don't push passed 1.4v if you are beginning. And don't over do anything, after spending time reading up more on forums and getting to know the voltages and what they can do a beginner shouldn't push to hard. Patience, time and knowledge is what makes a successful overclocker, Know your components! Im hoping to attend more of these events and start getting involved in our leagues, South Africa's overclocking community isn't big but it's growing steadily and I hope to introduce a few of my friends to our community.
