Q6600 OC - What should I be able to expect?

semiconductorslave said:
If your cooler uses the plastic pins to go through the MB you could always buy the 775 retention bracket. Xigmatek makes one, I bought the thermalright one and use it on my xigmatek cooler. The screws have springs that press the cooler legs down against the MB which is then reinforced with the x shaped back bracket. I have seen reviews that say this helps CPU temps a little due to the increase in pressure between the contact surfaces. Might be worth the $10.

I have my Q6600 under a Xigmatek 1284EE with that optional crossbow retention kit. I can vouch for it. Definately worth the few extra bux!!!

I can also vouch for that retention kit. I am still experimenting which way I should aim my fan though.

Well in my case, the airflow is reversed, so to speak. Fresh air comes in from the rear of the case. Generally speaking, you want your "hot" air removed as soon as it passes through your CPU cooler. So, that means (generally), that you will most likely benefit from your CPU fan pushing the heated air out of the back 120mm fan (if your case supports that scenario). Each case is a little different. What kind of case do you have and do you have it modded in any sort of way?
 
I have an antec 900 but I don't know how I should have it set up. I am sure you are familiar with that case and as you may know it only comes with 2 front fans but I added a 3rd on in the front. Also I added one in the middle. What I don't know what I should do is have the air go from the bottom up through the top fan or just straight pull from front to back. What do you suggest?
 
I'd point your CPU cooler to blow towards the rear of the case so that rear 120mm fan can remove the heated air as effeciently as possible.
 
Thats how I have it right now, but not why pointing to the top where my 200mm fan is at?
 
As I recall, the top fan is not centered with the CPU socket. It more than likely would not be the most efficient way to expel the warm air caused by the CPU cooler.
 
Its not perfectly centered but the Fan covers up the whole Heatsink and CPU so it shouldn't be that bad. BTW what kind of temps are you getting with 3.6ghz?
 
Yea i tried doing that but I didn't know how to fill in the gaps correctly since AS5 is kind of thick it applies to much. Next time I will try and use a razor blade or something.
 
Well, I think it's going pretty well. I'm @ 9x 340 (3.06Ghz). Every time I try to change the multiplier, it fails to boot. Not sure what's going on there. Even if I do 8x 300 & stock volts... I'm Prime95 8+ hours stable running Torture Test/Blend. Right now I'm pushing 1.400v via BIOS (1.384v in CPU-Z), and temps @ 100% load in the 8th hour are:
Core 1: 60
Core 2: 60
Core 3: 52
Core 4: 51

I think I have some more headroom in this...but I'm not certain. On Idle I drop to 38~43. When I try to push the FSB between 340 ~ 350...I can't seem to get it stable. Again, I'm trying not to go over 1.45v. Could this be the mysterious 'hole' I keep hearing about? My ram is running 2.1v @ 5-5-5-15. Should I push to 360Mhz on FSB and see if maybe I can bring in stable..??

Just a thought...but I noticed in Intel's TAT, I can only stress the first 2 cores.... Cores 3 & 4 never get touched. Is there another version? I have 2.5 I believe.
 
Night Ops...
1.4 volts for 3.06Ghz and 3.15Ghz seems kinda high.

I'm running 3.15Ghz at 1.22 (99% stable - occassionaly dies waking from hibernation) and 1.24 volts - (hasn't crashed yet)

What are all your other voltage settings in the BIOS?

As mentioned on the first page - here are my normal running settings

CPU = 1.22 or 1.24
DDR2 = 2.0
CPU VTT = 1.2375
ICH = 1.5
MCH = Auto
CPU GTLREF = 67%
 
This is [H]! Go for maximum speed now!

As for the temps, Xigmatek HDT-S1284EE is a really good cooler, what else can I say?

WOW 3.861 and on load you are only gettin 43C that is impressive. That beats a lot of water that I have seen. Right now I am at 3.6ghz with 1.39 on Load but my temps go up to 65C on to "In-Place large FFT's". I have the HDT-s1283. What is your ambient temperature btw?

Open case and easily lower then 60F in the room. Plus Prime fluctuates the load on the cpu so I just luckily caught the low load. Right now at 51 48 48 50C, case closed getting ready to pass out.
 
No wonder your temp is so low. I am at around 27.3C which would be ~81 F. It actually feels a little hotter than that. I have an Central AC but since this is the only hot room in the house it would be a waste. Thinking about getting a small window AC. Can you go to a higher clock speed btw?
 
Yes, already hit 3.9 last week, passed 10 runs in IBT but I went up there with a lot of voltage settings on auto so oc requried hefty vcore. Just waiting for new fans to arrive to replace stock Antec case fans and in meanwhile working out all the voltages.
 
Are the Antec 1200 fans the same as the Antec 900? My antec 900 fans don't bring that much air in. Was thinking about getting those Scythe "slipstream" fans and just control them through Uguru so when I am in idle it won't be too loud.

I'm running DDR2 @ 2.1v (OCZ Reaper kit, this is supposedly 'stock'). Everything else is Auto.

Don't forget, my VID is 1.3250, and my batch is L81XXX, pack date 8/2008..so it's a newer SLACR.

I'm going to try to drop Vcore and see if it holds out. Right now I'm 36C idle on Core 1 & 2, 26/28C idle on Core 2 & 3.

Either way, all my temps are well within range. I think I may have left it @ 1.400v trying to hit 3.2Ghz & up. I can probably clock it back down to stock 1.3250v.

I'm running 2x Slipstream 1900s all-out, and my case really isn't any louder. It's 37dBa, which is really fairly quiet...especially since it's moving 101.3CFM per fan.
 
yeah I got a q6700 g0 with a super crap vid 1.325 or something. My case is pretty small too with so-so cable management (lian li pc60usb). I'm stable at 3.2 with I think about 1.3 vcore. When I try to hit 3.4 I have to use close to 1.4 vcore and my load temps start getting unacceptably high (67c).
Was hoping for more out of this chip. Should have spent the few hundred extra and gone core i7.

Yea, they're not enough at all for hardcore overclocks; Antec case manual lists max airflow as 80cfm but I seriosly doubt that. So I ordered a couple of Scythe Slipstreams to replace all the fans in the front and move the only "slipstream" fan in the case off the cpu heatsink and onto the side intake.
 
Yea I replaced the one in the back with Scythe 3000rpm with 133.60 CFM . They can get pretty loud but that doesn't really matter because when I am not doing intensive work I just lower it with uGuru. I am also going to get 3 slipstreams for the front since the stock antec 900's aren't that great for hardcore overclocking as deadskull says. Btw didn't know 3.6ghz was insane overclocking lol. Oh if you guys are looking for some good ram Frys has the Patriot Viper 6400LLK Ram http://shop2.frys.com/product/5478999?site=sr:SEARCH:MAIN_RSLT_PGwhich can hit drr2-1200 speeds, that is what I've heard I just got them today.

uGuru? Do you have a scythe "Ultra Kaze" 3k rpm with just a 3 pin connector and you can lower the speed?
 
Yes I do I have scythe "Ultra Kraze" 3k Rpm fans connected with just 3 pin connections and can lower their voltage down to 6v to 12v. At 6v they are quiet but at 12v those things are loud. Uguru is some from ip35 pro its supposed to be used for overclocking and fan control from windows but I don't trust it for overclocking only thing I use it for is voltage control my fans.
 
Ok...I can boot into Windows and load up CPU-Z and CoreTemp @ 3.15Ghz (350x9) with RAM @ 5-5-5-15 @ 1.8 & CPU @ 1.3500. Temps are 36-36-28-29 on idle, Prime95 100% load temps: 60-60-52-52. Under small FFTs and torture test, my screen goes completely nutz (huge artifact-ish lines across the entire screen), and then it reboots. 340x9 is rock solid, with Vcore 1.3250. I'd like to push this to at least 3.2...where can I start?
 
on mine, Nightops (see post earlier in thread for my thread references)

I can get to 3.15 with barely any voltage increase. (from 1.2 stock) to 1.22 (or 1.24 for complete 100% 24/7 stability).

But to get to 3.2Ghz - I need about ~1.4 and my heatsink can't hold up to 1.4 volts...Also note that I can hit 3.6Ghz at about the same voltage I can hit 3.2Ghz -- so that's a little weird oddity.

So there are mini 'ceilings' along the way.
 
ive gotten mine to 3.5ghz stable, it starts to eat volts up once you pass 3.3ghz, 1.475v for 5ghz stable over here.
 
Also the thing about the q6600 is prime 95 and intel burn in aswell as a ram/gpu stress is a must.

Run everything at the same time, see if it stays stable for 15 cycles, then you know your voltage is proper. Alot of the times id run to test 7 on 1.42 volts but after about 14/15 runs a core would fail.

This causes unstable "hitchy" frame rates for alot of games. So if I were you bump the volts to 1.47-1.48 if your hitting 3.5-3.6 stress it and if its stable slowly bring it down again.

65NM chips love volts, even 1.5 wont kill most chips but regardless if you have good cooling you should be alright.
 
I need 1.49v to get stable at 3.6Ghz. Mine is a G0. Sometimes you get a good chip, sometimes it's not so good. 1.384v for 3.6 is a helluva chip you have there.
 
My q6600 is a vid of 1.23, currently bumped the OC to 3.6 @ 1.38 on air. I think i will go for the 3.8 and let you guys know how it goes.

Thanks!.. I had a QX6700 that just loved voltage but it was a pain in da butt to get it to 4ghz on my old vapochill setup. When I got my Q6600, I've hit as high as 4.2ghz (only for benching purposes).

Awesome.. When I bench on Everest, I see almost no difference (and even take a loss on memory performance) when going from 3.6ghz to 3.8ghz. For Q6600's, if you can maintain a safe 24/7 operation, 3.6ghz is the "sweet spot". I've had mine at 4ghz for a bit but honestly that's reallllllly pushing it (benching purposes only). My vcore really starts going up after 3.6ghz.

Q660040ghz.jpg
 
I don't trust everest memory benching... I went from 800mhz (5-5-5-12) ram to 840mhz (4-4-4-4) and my bench scores actually went down... even had them set to 1080mhz at 5-5-5-6 and my benching scores didn't see an improvement.
 
right now I can give you benches of my 840mhz at 4-4-4-4 and 1080 at 5-5-5-6. Since the 800mhz at 5-5-5-12 is on my other PC. Let me run the benches again. be back in a few minutes for those shots

Well it seems that they did improve maybe I had some programs running around in the background the last time. Oh well.
