Q6600 G0 - bad clocks off latest batches?

[t_ski]

I had mine up to 81C running Prime95 and it didn't freeze either. cAn't wait to put the watercooling back in...

 

[Mussels]

I picked up mine on 3-13-08 and It needs 1.475 to do 3200...I can get It stable at 3300 but It needs 1.55 and even on water I don't look at It as a good risk/reward tradeoff.

Was looking for 3.4 or better.....but what can ya do......I'm happy.....Just not OMFG happy.

thanks THATS what i'd been seeing - a few that couldnt break 3.2+ without going over 1.5v


Whats the batch code off yours? when was it made?

 

[Kursah]

Alright, well I just got the Quad fired up...decided to hop on and make this post before I start OC-ing...

Batch: L804A757
Date: 3/17/2008

Core Temp says VID is 1.30v, box says 1.35v Max. So far running good stock...no issues, running as cool as my e6300 thus far...but this is stock so we'll see what happens! Gotta learn my GTL and VTT settings as I know they're important for OC-ing Quads.

I will report back later with my Q6600 G0 OC results.

I'm having to use the same DRAM Divider as you...the 5:6 333/800...I could not get 4x1gb of this G.Skill HZ even Memtest stable using 266/667 (4:5 iirc)...I tried 400FSB, with 4:5...no matter what I changed...no stability..I didn't try 2 sticks as I plan on running 4GB in my rig so 2GB results isn't useful knowlege for me until I know I have my rig completely stable as it is. But at 420FSB, 333/800 (5:6) DRAM ratio, 5-5-5-12, TRFC 52, Performance: AUTO (sets to 7), + 62mv on CPU with 8X multi for 3360 CPU seems at least Windows bootable and Memtest stable. I haven't done a full run of Memtest since it can take a long ass time w/4x1gb in comparison to 2x1gb...I'll let it run overnight...did let it run for 20 minutes tho.

My goal was 400FSB, 9X Multi and DDR1000 on 4:5, but I was trying the last couple of days with my e6300 and I dunno what it is about that ratio, it just won't work lol! I did try running stock CPU speed and a wide variety of settings to no avail, so for now I am giving up for the 333/800 for now...I may drop to DDR960 if I can attain 3.6 at low enough voltage.

The CPU hasn't failed to boot yet...I accidentally booted at 9x420 for something like 3.78 on stock volts...hell it posted no issues, Vista wasn't happy, but if your OC isn't stable I've noticed it'll BSOD or fail to boot or some sort of error to letcha know quickly.

I will post my settings when I'm done, I know this is a good P35 board, I just didn't have to mess with as much on my trusty 'ol dual core2duo! So far tho, I'm impressed with the temps of this quad core, and that I have only reset CMOS when I swapped CPU's (just to be on the safe side). More to come...I do see this isn't going to be the easiest OC, but I will succeed, 3.4-3.6, DDR1000-ish, less than 2.2v on DRAM, and decent temps on air (summer is coming after all...couldn't tell up here, it's still like winter aside from a small handfull of semi-nice days!).

 

[PaulieG]

I recently bought 3 Q6600's from Fry's recent sale. None of them would OC stable over 3.4 stable, regardless of vcore. One wouldn't budge over 3.2. All three had packed dates in March. Boy was I disappointed. Sold all three...

 

[erocker]

These newest Q6600/Q6700 chips seem to not OC very well. Intel must be really reaching low in the ol' bins for these! I would like to see a newer packed chip that proves this statement wrong.

 

[Mussels]

ok so it seems any made in 08 have good chances of being crap OC'ers, stuck at 3.2 as i thought i was seeing.

Thank you very much to all who have posted here - anyone with a chip made in 08, please continue to post your details.

 

[mitsirfishi]

mine needs just 1.5v to stable 3.6ghz going to see if the magic 4ghz is possible

 

[Mussels]

mine needs just 1.5v to stable 3.6ghz going to see if the magic 4ghz is possible

still thats a lot higher than the 1.425 i need.

 

[Kursah]

So far I'm at 425fsb, 333/800 (4:5) DRAM Strap, 1.41 vCore, 2.12 vDDR 5-5-5-15 and DDR 1020 speed, and doing okay. Haven't run the full stress yet, plus I'm at work for another 5-ish hours...but that puts my Q6600 at 3.4 with an 8X multi...if I can get these settings stable, I'll push further.

I tried for a while last night to get stability with just the memory at 400FSB with both 333/800 and 266/667 dividers with no luck...I was close tho, so I think I'll try again tonight with the lower FSB. Dunno why a higher FSB would allow a more stable OC, but oh well. If I can hit 450FSB, that'll put me at 3.6 with 8X multi...of course that'll crank my memory up quite a bit, dunno if it'll maintain stability or not...

I'm still hoping to hit 3.6 with less than 1.5 vCore, but it's sure putting up a fight. I'd probably have an easier time trying with just one kit of G.Skill installed...but I'm too stubborn, and dammit, I'm gonna reach my OC goal pushing 4 Dimms! Really I've met my OC goal...if it's totally stable, but I gotta see just how much more I can really get out of it. Once I do get my settings ironed out, I will post in Code format for other DFI users to see.

 

[mitsirfishi]

still thats a lot higher than the 1.425 i need.

its pretty bum wish i could put <1.45 for 3.6 but gota see what she can do still

 

[imperialreign]

Lately i've been seeing a lot of people struggling to overclock their G0's - needing around 1.5v or so to break 3.2Ghz.

I'm trying to sell my Q6600, and a few doubters are saying my lapped quads that do 3.6GHz at 1.425v arent very special, while i'm arguing that the latest ones seem to be utter crap in comparison.

Anyone out there who got a Q6600 late 2007/ anytime 2008 want to share your max OC, and what voltage it needs? (esp. 3.2Ghz+ range)

I purchsed my G0 back in Feb/Mar this year, right now she clocks at 24/7 @ 3.6GHz @ 1.45v with BUS set at 400 and multi of x9. I'm defi sure it can go higher, but I'm waiting on snagging a water setup before I start aiming at 3.8 or 4GHz. Although she's been lapped, I'd rather be sure my cooling solution is up to snuff.

Still, though, I can't go below 1.45v in BIOS at current settings, but CPU-Z reads vcore as 1.43v (ASUS board).

I've been able to get to the desktop and run a few small applications with this CPU set at 450 BUS with a multi of x8 and vcore at 1.48~; but I never got a chance to fully stability test the OC.

 

[TeKniK]

i've just managed to get my quad bought last november (packdate oct 07) to 3.51ghz on 1.46v (1.5375v in bios)(damn vdroop lol) im gonna try higher but currently stable with the following settings on my p5k...

cpu voltage: 1.5375v
cpu voltage damper: enabled
cpu PLL: 1.50v
vdimm: 2.10v
fsb term: 1.40v
nb voltage: 1.40v

i have 4gb ocz plat 6400 @ 390mhz 1:1 ratio wih cpu 4-4-4-15 2T timings

im currently getting temps between 37 - 54 degrees so this is fine with a AC Freezer 7 pro

 

[Kursah]

Well I'm starting on a fresh slate...while my settings before (see previous post) were boot stable, I could browse the web, even play some games (Witcher, C&C3, etc), and I could even bench for approx half an hour before my rig would reset, or if I stopped the test it'd reset...didn't matter what divider on CPU or Mem I used...was pretty damn aggrivating.

So I decided instead of hoping that because I ran 20 minutes of Memtest ISO that my memory was stable, I would set it to stock and then a little less...

So I am at 400 FSB, 333/667 (1:1) Memory Divider, DDR 800 w/ 5-5-5-15 and 2.075v...15 hours memtest stable (worked all day, got off work..went fishing for a lil' bit, caught a 34" Northern Pike..first decent catch of the year...WOOT!)...so I have that part set. That was on 1.37 NB, 9X CPU Multi (3.6GHZ) and +200mv (approx 1.45vcore), 1.45VTT (still trying to learn and understand this setting), but I also realize that Vista is picky about stability which I am actually finding to be more of a good thing, and a useful tool for overclocking. For now I am working on the tuning, my CPU goal of 3.6 is still a strong possibility at this point...if I know I can get stable at that CPU speed, I will then work on the memory OC...but really with all the memory tuning this DFI board has, and the minimal tuning I did for the current DDR800 settings, the speed/latency losses were less sever than I expected...I was quite pleased...so losing the OC there isn't leaving a sour taste thankfully.

I can tell I have many hours left on tuning and overclocking and of course trial & error, but learning to OC a quad is very interesting, and actually having to utilize more settings on this board is also interesting, plus I'm motivated to succeed on this overclock even if it doesn't end up 24/7 set. More to come!

 

[Mussels]

thanks to everyone whos giving your input on this. Its quite a good point to keep using the packdates as opposed to the time you bought it, as it seems the changeover to crapper chips occured somewhere in early 08.

 

[t_ski]

Kursah, are you actively cooling you ram?

 

[imperialreign]

I wonder, though, for some of us if OCing issues might be more related to the motherboards as well?

Only mentioning as the last time I was tweaking things down, known good settings would start to not work, and would fail POST - twice I've had to reload BIOS defaults, and even then this board would come back during POST with a message of "Unknown CPU installed"

IDK, maybe those issue were just a buggy BIOS, as I've since updated - but I haven't pushed my clocks any further since then either.

 

[Kursah]

It's odd...I'm still having issues with Prime Blend (4 Core)...it'll run fine for about 30 minutes...I have my VCore increased to +212mv, approx 1.46 on load...then after a few minutes it'll start switching between 1.46 and 1.44...and then 1.44 to 1.42..then it'll stay at 1.42v and that's about when the 30 minutes is up and my PC restarts. My VTT is set at 1.45...which reads about 1.47v, GTL's are at x63 (I've tried x63 and x67...haven't decided if this is doing anything to help or hinder yet).

Anyone else notice this? Starts out strong...my cores were hitting about 56-62C after a few minutes of load...then the voltage started slowly dropping until it hit 1.42...kind of aggrivating at this point, but I'm not giving up yet. I am gaming, browsing, and anything else just fine...but I won't be satisfied till I pass my synthetic stress test!

Kursah, are you actively cooling you ram?

Yep...see sys specs . Have been for over a year now, and I'm still impressed with the Corsair XMS Airflow...damn good unit imo. Keeps my memory pretty cool to the touch.

[Nitro-Max]

I actually managed to boot to windows on just 1.110v today lol @stock speed.

my vids only 1.2750v i think i got a cherry picked quad 1.360v for 3.6ghz

im seeing alot of quads needing 1.5v to get 3.6ghz latley with vids of 1.350v

ive still got 15c overclocking room left on air!!

 

[Kursah]

I've got a 1.30v VID chip...but I'll be damned if it doesn't seem to hemmorage voltage at higher OC's lol! It may be a sign that I should back off...but I am still curious to see what it takes to get 3.6 stable. I'm still happy with the quad, and for $190 shipped, I can't complain...same price I paid for my e6300 when I built this rig.

Thats vdroop. either your mobo or your PSU isnt coping with the strain/heat.

 

[Kursah]

If that's vDroop it's the largest I've ever encountered..my e6300 didn't cause nearly the ammount of stress. Though I am running higher voltage on almost everything (aside from memory)...and the heat is increased quite a bit on all fronts (aside from memory also).

I just got done gaming for a couple hours, not a hitch, not an issue...I will continue tuning, but I had to take a break and use this rig for what I built it for! Lol! Well supposedly this board is meant for quad-core OC-ing, and my PSU really shouldn't be strained that much...it'd be worse if I was still running my OC'd x1950xtx lol!

I have a lot of tuning left to do, more to come!

My bet is that your PSU is starting to droop a little (12V rail drops a bit as it heats up) and its affecting it - yes its a good 520W PSU, but you'd be somewhere between 300 and 400W usage, and if a lot of its on the one 12V rail (same as CPU) it could be having an affect.
