Hi, I have my Q6600 @ 3.6ghz with 1.45v , he is lapped with a thermalright TRUE 120 lapped too (penny mod), nanoxia fan @ 1250 tr/m.
Idle : 35° c
Load : 65°c
Do you think my temps are normal ?
temps seems normal with 1.45v.
with more powerful fan u can cut of around 2-3*c
something like 1600-2000 rpm, + 60 CFM
I am now playing around with my q6600 that I got from canada off ebay! L737B011 It has a vid thats 1.325, but I have had pretty good results so far (have just done a little testing-will be doing more for the next week)
Right now its priming at 3.8ghz 60C load, I might be able to even drop volts a little bit. Currently at 1.56v Anyway what is the max volts for these according to the intel spec sheet, or personal experience?
An interesting thing that I found, was that when I was using p30 bios with 680i temps read about 10C higher, but now with p32 bios temps are reading 10C lower...which is a good thing :) I am going to double check this as before I was using vista and now am on xp...
I was not able to boot up past about 3.7 without decreasing the multiplier, which I assume shows a fsb in the 680i... no suprize there :)
EDIT: update-not prime stable yet, 1 core failed rounding after 15min
Imo 1.56 is too much but taste according your flavor .i personally won;t go over 1.375 because i think that my Quad doesn';t want do die young (:
With your VID I think you need 1.475v - 1.5v for 3.6ghz occt stable.Quote:

But with vdroop, when you set 1.50 bios, you could shoot up to 1.6v. A good way to estimate the spikes your chip can get is to disable vdroop compensation, set bios till you get your stable vcore after droop. And, the bios set value should be an appreciation of overshooting voltage your CPU is getting.
There are no stories of intel 65nm chips dieing in few months under 1.55v, so you could run safe for few years maybe.
I have done a vDroop mod, so vDroop is basically non existent now :)
Hi all! some results from ysterday :
http://www.2send.us/uploads/5515c15029.jpghttp://www.2send.us/uploads/232ba07a58.jpg
http://www.2send.us/uploads/252594cf92.jpghttp://www.2send.us/uploads/13a3e24a89.JPGthe Vcore is not 1.3750 it's 1.425 in BIOS Vdrop is 0.03-0.05V.
Temps on load 56-59 C
if i didnt change the GTL of the CPU&NB it wont boot...
it's still not rocksolid,solid enough to play crysis though...but not OCCT.
got any ides how stablized it with less voltage?
what else can i do?
vSB is too high, no need unless you have 4-6 HD in raid, and even with that...
vNB is too high for that FSB, try lower
Give a screen of upper bios settings: I can see that transaction booster is on auto, should be disabled, relaxed to 3 to start. Static read control to disable to start.
vDDR at 2.20v could be not enough to run your RAM at 1066MHz, ususally you'll need 2.25-2.30v
If Prime95 small FFT is stable, your problem is not vcore
If by OCCT, you mean the RAM mode, than it is in the NB-RAM settings where you should look for, like I explained above
the memory is G.skill pc2-6400 4-4-3-5 (promos) and they are stable 8 hours in memtest.crashed both prime95 and OCCT after 4 or 5 hours.
i will try setting the SB NB lower and i'll update.
i'll try occt ram mode and putting the ram on 800 5-5-5-15 just to check.
Static read control is disabled. i'll post a pic later.
thanks for the help. good night.
Yes but he says that @ 3.8 one core fail after 15 min, so for me with that vid he can be stable at 3.6 with 1.5vQuote:

Also, the SRC is less stressing than Transaction booster on high overclocks. So, I'll disable both to start relaxing the booster to 3. Once your memory is stable, go with lower CAS tests. Once stable, try to enable SRC/Booster or relax it to 0
Depends, 90% of the VID quiz is correct
the more VID the more Vcore to get it stable, but sometimes is not...
I had a Q6600 L723A VID = 1,2875 and requiered 1,475 vcorebios to 3,6ghz prime stable
Now I have a Q6600 L737B VID= 1,225 and can do stable:
vcorebios= 1,325 3,6ghz
vcorebios= 1,432 3,8ghz
and benched 4234 on air at 1,625 vcorebios

Wll guys i've hit the wall at 9X424. no boot no whether what i do.
didnt try to make solid more than i need to bench it.just wanted to know how far can i go.this as far as it booted to windows.9X423 booted too. http://www.2send.us/uploads/45a4609392.jpghttp://www.2send.us/uploads/706e823f58.jpg
SRC-disabled
transaction booster disabled -3
NB - 1.70 (less it wont boot)
SB - 1.20
CPU GTL-x63 (if it's less it wont boot)
NB GTL-x67 (if it's less it wont boot)
Vpll-1.60
Vfsb-1.30
Vdimm-2.2
i think my mobo cant do with 4cores any more than that.
jonny_ftm i did test it with 800 5-5-5-15 and it was the cpu.
at 3.6 it needs 1.400V to be rocksolid . just cant get it to be less.
Did you try more vfsb?Quote:

Or maybe there is a fsb hole, try 50ish higher with lower multiplier
I am running ver. 1101, with my current set up, P5B D,with voltage mods,E6600 cruising on water at 3.4, PCP&C 750, Swiftec water on cpu, NB, & video. Antec P180 modded for water
I just got a notice from micro center. Q6600 for $199.00. Im ready to jump in the car. Any recommendations
I was going for 3.6ghz. I took it up to 1.5v, but it's still unstable. Is it my board perhaps?
I just picked up 3 Q6600's from Fry's by pricematching the Microcenter $199 price. All G0 SLACR's.
The one I targeted for my desktop (the other two will go into servers as upgrades) is a L739B890, and has a VID of 1.2250v. I can overclock it to 3.420Ghz (380x9 FSB) with 1.35v with no issues.
One weird thing though is that according to core temp (0.96.1), core #1 and 2 always run hotter than cores 3 and 4, usually by 3-4 degrees at idle, but 6-7 degrees under load. I am using a zalman CNPS9700, and the motherboard is an asus commando. Is this normal, or is something screwed with my thermal paste or something else?
I have two other Q6600's, batch numbers L745B154 and L745A675. Does anyone else out there have those? Do you think I would do better with them than with the L739B890?
One of them will not be OC'd, but the other will go into a server that does a lot of transcoding, so I plan to overclock it as well, but the best overclocker I want in my desktop. ;-)
Thanks!
My same 2 cores run hotter when idle as well as under load, exactly the same cores, and about the same temp diff. as yours. I wonder if it's a designed thing, or if it is a byproduct of the design.Quote:

They both act the same, but booster is more agressive and can be manually set. Ususally you can't activate both if you OC memory. Booster should not be auto, as it will be relaxed to 3. Better disable and relax it less so you get more performance if your memory handles it. Relaxed to 0 will give a good emory bandwidth improvement on benchmarksQuote:

i think the board is having realy hard time with that 425 bus...i'll try to override it and do 7X450 see what happens.
Hard to believe the P5K Premium is limiting your FSB. But maybe your CPU has a low FSB wall
Elio I had the same Issue with my other Q6600 L723A couldn't reach more than 460x7 and couldn't boot at 450x9
I have a P5K deluxe and i love this mobo, i started to think that it was her causing that wall but i was wrong it was the quad...I now have a Q6600 L737B and can do 485x7, 450x9 and all mobo settings at min values (SB,NB,PLL)...So the wall was the batch...

You also confirm that these P5K series are really great boards. Nice OC for that low vcore. Your temperatures are load? As I see Prime95 in the background. You got a very good chip. I should also migrate to that Fusion + Washer like you. The GT is limiting meQuote:

Only 56°C load on small FFT at 25°C ambiant, that's great, really. I take 10°C more at same OC and same ambiant but with 1.43v too, maybe that's the problem. To have lower temperatures, I need a 20°C ambiant.Quote:

I can lower the VCore some more to get it stable and its not my ram... Motherboard is a P5B Deluxe that i had running 520 1:1 with my 6420 and my D9GMH. WTH ? I think it might be this bios. any ideas ?
I dont believe that quads and the P5B go very well together. You need to move to P35 or X38 chipset to get the best out of it.Quote:

More vcore should get you higher - Its only the later batches that seem to get 3.6 on low volts. I need above 1.4v but it idles 35c load 60c so thats good enough for me. Quads dont start cooking till they get above 70c .Quote:

I can't tell you more about the CPU as it was OEM.
i can choose from the following G0s....which one is better for OC results? will be using it with the DFI DK P35 mobo.
~L738A
~L744B
~L740B
Aiming for at least 3.2 (3.6 is probably what I want ~50% OC)
It's quite possible that you are using too much voltages on the NB/CPU PLL/FSB.
Try setting the board to auto on voltages and manually set the FSB and multiplier and see what the board does for you. Might be suprised.
i´ve got one L740B running 3.8Ghz@1.37v 110% primestable on DFI DK P35Quote:

Would do much higher (already did 3.9 GHz) but alas I’m only playing with a slicked up tuniq tower but my 830's fans help out. Low 50's load, 30s/40 idle. 21c room temp.

I plan on keeping my computer on 24/7, its stable at 3.6 now, but it takes 1.435v under load to keep it prime stable. I would have to run about 1.5 to get 3.8 from my limited testing.
Do i keep my q6600 at 3.6, or go for 3.8?

Hey Jonny
What are the advantages of the P5K premium over P5K deluxe
Cheers
Sergio
P5K Premium is supposed to have new PWM with better quality and less heat, to optimize quadcores overclocking. If you buy a new mb, go for the premium, if you have a deluxe, I don't think it is worth the upgrade as the deluxe overclocks very nicely on the forumsQuote:

Ok,
I can run stable 450Mhz x 8 or 422Mhz x 9, but I cannot get 450Mhz x 9 to hit 4Ghz. Temps are not an issue, I am water cooling, so my temps get to only 60 degrees under severe Everest load with P95 running also at 3.8Ghz and 1.5 volts. Anyway, I think all I need is a little more voltage, however on my Gigabyte MB (P35-DS3R) if I put the cpu voltage on 1.6 I only actually get 1.5 do to Vdroop. The next step is 1.8, there is no in between, and after Vdroop would probably be 1.7 or 1.75. I think this is too high for this chip, has anyone gone this high on voltage? Any advice on getting it to 4Ghz? By the way, I have added .2 to both MCH and the Northbridge voltages and that doesn't seem to help. My next step is to try and see what my FSB wall is, it may be possible to get to 475Mhz x 8 which would equal 3.8Ghz. Since I have already hit that with 422Mhz x 9, that really isn't much progress. Has anyone hit 500Mhz on this chip?

Just got my new G0 Q6600 Batch# L750A892 with VID of 1.2625V and currently testing on my IP35pro and voltage in bios is set to 1.5225V and on prime95 load,it drops down to 1.400V.Is this ok?Seems like mine needs a lot of voltage to run at this speed.Anyway here's a screenie and i know 2 of my cores really hot(70+C:eek: )but it's because i got me a crappy Cooler Master GeminiII.Only been running 15mins but so far so good.Hopefully stable.

PCB revision is 2.00G if I remember, CPU-z shows that. I never saw a P5K Premium with different versions. But, there's different caps/box/boo color versions. Also, there's 2 PCBs: made in taiwan and made in ChinaQuote:

The first shot is max bench under a prommy. Second is my 24/7 oc on water. Its a l373b262 vid 1.225

I'll post some screenshots here once I start overclocking it, I just got my system setup tonight. Mine has very good contact with my Apogee GT block, all cores reading the same Temp except core2 which reads 3C lower.
Has anyone seen Q6600 L744A469?
The google search couldn't find anything on it.:confused:
Only thing I could find, was a foreign site. The guy had an L744 stepping, that was the most info he provided on the stepping. Looked to be a good chip.

So I decided to buy a new Q6600 with low VID and I got this batch: L745A793! The VID on this batch is 1.2125v.
It's amazing so far, my DFI X38-TR2 used only 1.20v on Auto vcore option to run the Q6600 at stock speeds (the high VID one used 1.32v).
I have everything in auto so far and going to start overclocking this new baby.
Also it's running Prime95 3600Mhz (9x400) with 1.25vcore, 1.23Nb and 1.21Vtt :up: Impressive compared to my old Q6600.
So the best thing to do if you wanna get a Q6600 these days is to scout for low VID voltage.
Forgive my noobness. But when purchasing, how do you find out the vid voltage and batch number? I'm under the impression the batch number is on the CPU itself.
The Batch number is located on the retail box, as well as the cpu. You won't know the vid until you actually install the cpu and use coretemp to view the vid.Quote:

I have a Q6600 L740A978 is a good chip ??
I need a good Q6600 because my next computer is wc and want to do 500x8 for the party of my city, the memory is a gskill ddr1000 and need a good Q6600, the mine is better or need to looking for other ??
My Q6600.....3.825GHz (425 x 9) @ 1.42V. Idle temp at 30-34 across all cores...watercooled. 430 fsb requires over 1.5V so 3.8 is the max I'm going to run.....and will probably back off to 3.6 for daily use (that requires only around 1.25V or thereabouts.)
At 3.8GHz, it's been completely stable through Prime 95 overnight and Everest stability testing for hours......stress temps in mid-50's.
Batch No. L745A871
Looks like some of the newer chips are getting nice low vid's.
Your friend is a lucky oc'er.Quote:

Ultimately, it's what ever you feel comfortable with. However, most Kentsfields can easily support up to and perhaps over 1.55v with decent water cooling.
Damn I hate you guys, my Q6600 needs 1.4V to do 3.6GHz and loads at 72C. :(
What cooler are you using? Throw some water on it and the temp should go down. Is it a B3 or a G0. B3's run very hot and don't OC as well. If it's a G0 you probably got unlucky and got a bad one.Quote:
