*Official Retail G0 Q6600 Overclocking Thread*

[sesdave]

Hey guys I received the Q6600 2 days ago, the G0 L723A wich was promising and recomended here also...it's VID= 1,2875..but...

The ambient temp was 25-26C
Crucials left near stock i mean near 1066 5-5-5-15 at 2,2 to asure to test the CPU only.

Boot at 3420Mhz (380x9) vith vcore 1,35 but prime95 fails, so i have to go for 1,4 for Prime95 to stabilize, 30 mins at Smallfft's, and Largefft's also. I have pretty high temps when Prime95 is runing i mean 69 the cores and 52 CPU...

I tried going up to 3600 (400x9) and boots perfect on 1,4Vcore, but Prime95 fails in seconds...So i tried more Vcore and it also failed til 1,5 Vcore wich is kinda sad...temps are very high i mean 74 the Cores and 60 the CPU...

I have an Asus P5K dlx bios 311 and TT Big typhoon with AS5 no lapped...
Wich settings are you using guys on ASUS P5K dlx for example to go to 3,6ghz ? With version of Prime95 you use (i used 25,5) and wich test or settings on it, i never used Prime95, just orthos....

It's kinda weird that prime95 fails cause in other CPU i had the lack of vcore always was showed by reboots, etc, but this time i mean at 3,6 and 1,425vcore y can play strangehold on vista, bioshok, lost planet etc...
It can be a temp issue ? should i consider lapping ? or i just got a bad batch...

Any help will be appreciatted
Best regards

These work prime stable for me. My CPU seems to like lower multiplier - higher FSB. I have a premium but its the same board with better capacitors. Use Coretemp 95.4 or PC wizrd 2008 http://www.cpuid.com/pcwizard.php to monitor temps. PC wizard displays temps on top/left screen when you minimise it. You really want a thermalright 120 extreme or Ultima-90 with agood fan to handle the temps - even then they can only handle so much. I wont take my volts above 1.45v. On current settings I idle 35c and prime 61c. If you want to consider lapping check HS and IHS with a razor first - if they are already flat there will be little gain. If one is uneven do it. This is as good a guide as any - http://www.thetechrepository.com/sho...hlight=lapping I used it when I did my old E6600 - use black wet and dry sandpaper(dont use water like some suggest).

You are so right about Asus Update.

I don't think they should even have the Asus Update. To much can go wrong in Windows. I had a board that failed the flash and would not flash again. I RAMed the board. I said the CrashFree BIOS 3 was defective.

I think EZflash is a great system for a bios flash. I also have never had a problem with AFUDOS. But, I think EZflash is safer.

Here's something I found a little strange. I have the MSI P35 mb, and was running 3 HD's, and 1 optical from the 4 ICH9 ports. I added a 4th HD and moved the optical drive to the extra marvell SATA port, which I had to enable. Hit the power, and the damn thing wouldn't boot! In the end, I had to remove a few sticks of memory and up the memory voltage by another 0.1v before it would boot with all 4 sticks.

Seems like activating the marvell port is causing a small voltage drop across the dimm ports. I guess it makes sense considering the laws of physics, but you'd think the MB would just draw more power from the PSU to support the additional requirements.

Anyway, just sharing since I thought it was a little strange (and kind of frustrating!).

Btw, kicked my FSB up to 450mhz x8 and same voltage on the CPU. This thing runs great!! Still haven't lapped it yet, and my core temps never get over 59c.

- Sker

That's strange you mention that, as I ran into the same thing with my single HDD (when I first bought my P5K) I couldn't boot with the HDD in a certain SATA port....can't remember which one that is.....
I also use the Marvell NIC port because I've never liked Realtek's drivers....
I find it hard to believe that it's actually a physical hardware issue. I hope that the engineers took the voltage/current allocation into account when they arranged the devices with the southbridge and northbridge, but I guess it's possible.

My G0 arrives tomorrow and it's OCIng time! I'll be sure to post my results.
Anyone running a Zalman CNPS9700? I may get an Enzotech Ultra-x if it doesn't cut the mustard, but I'd like to compare with the rest of the class

Most choose the thermalright 120 extreme cos it tops most of the test chart when running with a q6600. Its huge though and may not fit in all cases. I got the Ultima-90 which is a lot smaller but nearly the same performance due to design and number of heatpipes. http://www.overclock.net/hardware-ne...tima-90-a.html It holds near top of tests only a few degrees lower on overclocks..

I use to have Zalman CNPS9700. It was hardly capable to cool my E6600 on 3.6. I am using Thermalright 120 Ultra extreme now, with my Q6600 on 3.6, and it is cooling it very well. And it is not much bigger than Zalman. It fits on my P5E just fine.

[~aoe~]

I may get an Enzotech Ultra-x if it doesn't cut the mustard, but I'd like to compare with the rest of the class

I love the Enzotech Ultra-X. I have one installed on my Opteron 170 system and it performs slightly better than the Scythe Infinity with dual fans I had installed previously (replaced the standard Delta fan with a Scythe S-Flex 1200rpm). The Scythe Infinity with single fan performed more or less the same as my Ultra 120 Extreme when installed on my E6600.

I don't have a direct comparison of all 3 heatsinks installed on a Q6600 though as I'm building a WC system for the Q6600.

[andressergio]

Thank you very much sesdave !!!

I didn't try 1,4 on NB and FSB, guess that maybe a point

I boot perfect at 1,4Vcore so maybe is not a vcore issue maybe is that...also the ballistix perform very well..
Really thanks for posting your settings...

If found some cool things about this quad..for ex:

Ambient temp = 24-26 C

NB= min
FSB= min
South = min

3,0Ghz stable at 1,25v (333X9) DDR2 1200 5-5-5-15 2,2v (28C /30 Cores)

3,0Ghz stable at 1,25v (375X8) DDR2 1125 5-4-4-9 2,2v (28C /30 Cores)

3,0Ghz stable at 1,275v (429X7) DDR2 1020 4-4-4-12 2,2v (30C /30 Cores)

3,42Ghz stable at 1,4 (380x9) DDR2 1140 5-4-4-9 2,2V (33/43 Cores)

3,40Ghz stable at 1,4 (425x8)


For some reason using (x6) multi at (500x6) i loose my keyboard, and bios hung..so i upped FSB to 1,3 and cool..but windows (both XP and Vista) don't show the 4 Cores I have 0 Core Processor
Maybe again is that i have to handle better the NB and FSB voltajes

If anyone can post results at x6 multi will be appreciated

Thanks for all the help !!
Best regards
Sergio

[andressergio]

Well I guess it's a no go for me...

I tried as you said upping NB and FSB to 1,4 and testing memories lower but it fails till 1,45Vcore...kinda strange that fails inmediately, same as it fails with vcore=1,4 or 1,425

Also i can't hit 500x6 or 500x7 seems to be a wall

Well according to the charts posted at overclock.net the thermalright ultra 120 extreme is the way to go. I've read some today and noticed that myself. I'll probably wait around until Anandtech does a review on the Thermalright IFX-14.
I have plenty of room in my case, as I have a thermaltake armor full tower case, and I have good cable management. The only issue will be my OCZ XTC cooler, but that can slide over some to accommodate a larger cooler.

I wonder....has anyone tried any of those TEC/air coolers? I read a review on the Ultra Chilltec that didn't praise it much, but the temps seemed pretty good......I don't mind paying the price for performance. I don't really want to go water cooling........

[binormalkilla]

Ok I unpacked my G0, and I'm about to install and start OCing. Here is the stepping:
L737A823

[binormalkilla]

Well......I started with an OC the same as my E6600: (for in game comparison)
375*8
DDR2-938 at 4-4-4-12 35
I set all of the CPU related voltages to stock and the rest to what they used to be.
Now that I booted up two of the cores are disabled.....I'm wondering if this is due to lack of VCOre.....when I get home I'm going to set it higher, but anyone else have this happen? I have both 4 pin CPU PSU connections on my P5K near the socket.

In bios shown 4 cores ? if yes, then its your OS's problem. if not, then you need to update bios.

[andressergio]

Hey Bino !

I have the same issue, it's seems to be a wall for me at FSB > 1870
Tried 311 (best bios for me), 404, 601

(445x9) vcore=1,625 loads windows, but not stable, needs more vcore

(450x8) with vcore=1,425 can play games etc but prime95 fails fast, i guess it needs like 1,5 to be stable

(500x7) vcore=1,425 NO CORES, on everest, coretemp, etc (fsb=2000)

(463x7) vcore=1,325 STABLE (fsb=1852)

(500x6) vcore=1,3 NO CORES or BIOS just hungs, tried all and no go...


The best OC's for now comparing memory bandwidth, temps and speed and all was:

(463x7) 3.24Ghz
vcore=1.3250
1111 (5-5-4-9) 2.2v
(NB=FSB=1.4)
(temps shown are whith the cpu lapped and seconds after prime95 finished)


Very fast config, low vcore, low temps and very good bandwith


http://www.subirimagenes.com/imagen-...3-1572215.html

(425x8) 3.4Ghz
vcore=1.40v
1020 (4-4-4-12) 2.2v
(NB=FSB=1.4)
(temps shown are when it wasn't lapped and seconds after prime95 finished)


http://www.subirimagenes.com/imagen-...3-1572230.html

lapped 3-4 degrees lower


http://www.subirimagenes.com/imagen-...9-1572252.html

Best for all !
Keep OCing !!

I'm patentiently waiting for the thermalrigth ultra extreme for now the thermaltake big typhoon VX is struggling very good

[chuckbam]

In bios shown 4 cores ? if yes, then its your OS's problem. if not, then you need to update bios.

Or, completely clear the bios. I would take the battery out.

[andressergio]

Hey Chuck !

It's not a bios issue it's some limit...I tried 601 also, same and worst, at 500x6cannot even boot

Congrats on an excellent OC! What cooling solution are you running on it? If you have a P5K deluxe I'm sure you've found the FSB hole at ~334-370. Are there any other 'holes' after 400 MHz? I never clocked my E6600 that high.


BTW I'm selling my E6600 if anyone is interested. It's $170 shipped FedEx ground to continental US, but I'll adjust for USPS international. You can check my trader rating at overclock.net:

[binormalkilla]

Ok I'm already running 3.4 GHz and I'm stable for a single 1024K pass and counting on 4 Prime95s . I'm running VCore=1.38V according to PCProbe, and I believe that I set 1.425V in the BIOS. Before VDroop I was at 1.39V

My NB temp is 45C......is this too hot? I looked at the Intel thermal profile for the P35 and it said Tc max was 105C or so.....surely not!

This Zalman isn't the best cooler for quads....I'm getting 50C with my apartment door open, and ambient temps in my area are 11C according to my Vista sidebar.

EDIT:
Here I am at 3.4 GHz stable for 1h23min in Prime95! I'm going to run it all day while I'm at work tomorrow and check temps via remote desktop. Hehehehehe....I wish I could access the BIOS via remote desktop. I wouldn't get any work done for sure!

[andressergio]

Hey Bino !

Instead of (425x8) try (463x7) and then you tell me

You will have more bandwith, less vcore (1,325 Bios) prime95 stable
Set FSB=1,4

I found that's the best OC under 3,6 I could find, i tested a lot these days and the one I want that is (450x8) though i perfectly work with 1,425 on bios it just fail 1 core on prime95..so i started to search for another good one and i found it

Make some benchs on everest with the one you have now (425x8) and then with (463x7)

Best regards
Sergio

[yonton228]

So far I am running 3.6 with F@H SMP load 24/7 stable(only thing I care about is being F@H and gaming stable)

SPECS:

MOBO: Gigabyte DQ6 P965 REV 2 F11 BIOS
CPU: Q6600 G0 @ 3.6GHZ
CPU VOLTAGE: BIOS : 1.44 WINDOW ILDE: 1.392 F@H SMP LOAD: 1.344
RAM: OCZ Plat 7200 2GIG, 1:1 @ 800 4-4-4-12

I would like to run this CPU around 3.8GHZ however I am running 1.44V in BIOS. Now since it drops so much under load would it be safe to pump up the V in the BIOS to achieve a higher clock?

Screenshot (ambient temp is 18.4C during this screenshot)




PS: I am running a water setup I will list fully specs in sig later.

-yonton228/timmy

[andressergio]

I runned my E6600 during 8 month at 1,5 on air 3,6Ghz, the only reason that stops me with Q6600 quad is that i'm on air, soon as the thermalright ultra arrives will see, as i on summer i got more than 26 ambient so in winter it's my best shot

Till 1,5 it's safe and more with Water Cooler, but i think that it'll take much vcore to be prime95 stable...

I agree. I haven't spent much time testing and such, but I always get more memory bandwidth with higher FSB.....the difference is huge
I just ordered the Thermalright Ultra 120 Extreme today from newegg along with this fan:

here's the ultra:
http://www.newegg.com/Product/Produc...82E16835109140
I know a couple of people have these here....how do you like them? More importantly what kind of fan do you have on them?
Here is my stability test for 4h31min of 4 core Prime95....at only 3.61 because I forgot I bumped the BIOS down a bit.
What's really strange is that I can run this with no problem, but I INSTANTLY lock up in SANDRA arithmetic bench. I can run everest as well as 3dmark.....weird. I'm stable in Crysis too. I'm going to chalk it up to a bug/anomaly.

[jmmtn4aj]

This is weird. Previously I was using 400x9 with RAM at CL4 1:1. I was getting like 14.4 in SuperPi. Now running 450x8 with RAM still at CL4 and 1:1, but at 2.3v, I'm getting 15s. Wtf?

[binormalkilla]

Here is my new best 3dmark06.

[jarthel]

I have mine running at 3.6Ghz@1.37Vcore (100% load).

Correct me if I'm wrong, but I don't think that Orthos can run 4 threads.
