Working on my clocks and so far I'm doing alright at 9x437. Not real extreme, but it seems pretty solid so far. I can run 20 runs of ITB, memory is stable with memtest, 3D game stable & 3d bench stable. I just gamed for a couple hours, no crashes or wierdness. All on about 1.35 Vcore, 1.4 NB (GTL's all +13) & 1.275V VTT. I have got to run P95, if at least 8 hours stable, it's a go! Nice clocks without having to use very high volts! :up:

What's surprising me is the OCZ RAM. It's $50 1333 Gold series RAM, rated at 9,9,9,27 at stock. I'm running it 6,6,6,18 PL6, CR1N on 1.84 Vdimm. No extra cooling needed. The RAM is very cool to touch.

I've set 1.3675 Vcore in the BIOS, the BIOS reads 1.35V and Aegis reads 1.35V in Windows. Vdroop compensation is enabled. Under load, Vcore drops to 1.34V. Not earth shattering clocks, but it seems to be running well so far, now on to P95!!

Bloody hell!

Thats increidble with that RAM. My OCZ 1800MHz seems to have just deteriorated and caused me nothing but problems.

Nice, let's see if you can get 4Ghz. ;)

Bahhh.........at the original voltage I posted about failed P-95 blend after 2.5 hours on core #3. I grudgingly upped Vcore to 1.375V and P-95 blend ran for.......7 hours 48 minutes.......before core#3 failed :( That was this morning. Since then, I have regrouped and will continue my quest! :p:

I believe that the rule of thumb regarding P-95 blend, is that if it fails within 2 hours, it's cpu related; if it fails after an extended period >2 hours, it could be RAM related. I backed command rate to 2N from 1N and I'll prime again. If I have the same failure, I'll up v-core another notch. My problem is probably not enough Vcore.

However, this RAM will pass all 8 tests of Memtest overnight for about 25 passes, but throw out just one error in a single Test 4 pass when other settings have been used. 1:1, this ram will post at 14xx fsb, but give me that one error as described. So far, using either the 1.3.2 or 1.3 dividers, the RAM seems well behaved. I need to rerun my ram at these 1N & 2N timings just to make sure it's solid. I have solved this before by either lowering CR to 2N or raising Vcore. If all else fails, more vcore!

I nailed it down!:up: I ran at RAM at CR2N, different core failed after ~8 hours. RAM was not the culprit, back to CR1N and about 1-2% bandwidth recovered. Instead of raising Vcore, I left it at 1.375. I raised VTT to 1.35. Taking 2/3's of that value, I figured that I needed 0.9V for the GTL's . Using Saaya's GTL voltage chart, I figured I'd start by using a range of values. Using 1.35V VTT, my values to use were +9 - +12. +9 being 0.91V. Reset the BIOS, 1.35VTT, +9 GTL and went back to P-95.

This time, 10 hours 58 minutes P-95 Blend stable :D

Now to see where else this chip can go!

3600 seems to be hard but must be your next target

I was thinking of another direction, lowering the multi to 6 or 7 and seeing of I could hit 500 fsb. HOWEVER, that could be a waste, other than seeing what max fsb could be. I'm still only air cooling the NB with the stock fan. At 50%, the fan is quiet, however, during stress testing, I run it at 85%. At 85%, it sounds like a Hoover vacuum cleaner. To really push this board, I will need to water cool the NB. I'm liking that I can keep Vcore down so far. I have a very nice 24/7 clock with 437x9. I'm going to go back and try to fine tune this clocks with the 1.3.2 mem divider again to get more bandwidth from my RAM. Then this clocks will be set!

FSB 500 stable with a Q6600 is next to impossible. I wouldn't waste my time, plus it won't help performance one bit, seeing as you are way below the 4Ghz.

Sailindawg

10-25-2008, 05:12 AM

I agree. I was thinking of trying it as an exercise to what my max fsb could be. Agreed 100%. I have also purposely kept voltages down to see what I could get at lower voltages first. I need to water cool the NB.

Whelp, been going back at clocking this cpu. Here's my latest:

http://img399.imageshack.us/img399/130/8x4508hrsp95stablewj5.th.jpg (http://img399.imageshack.us/my.php?image=8x4508hrsp95stablewj5.jpg)

Vcore=1.475 V (x1 V multi)
Vdroop=enabled
PLL=1.508861 V (default)
VTT=1.425 V
GTL's=+12 (all)
NB=1.5 V
NBGTL=default
SB=1.5 V
RAM=1.84 V (running on 1:3 divider)

This OCZ Gold is still holding strong at 1353 FSB at the 66618 PL6 timings. Kind of wondering if I ought to get an 2x1G kit and go VISTA 64 as well. Not sure at all if these 1333 Gold's are the norm or I just got real lucky. The RAM seems happiest on either the 1:3 or 1:3.2 divider.

At these settings, I can also hit 9x412. So far I'm 4 hours P-95 stable, 3D gaming stable and WPrime stable. Unfortunately no screenshots. However, if I'm 8 hours P-95 stable at 8x450, I'm sure I'm also as stable at 9x412, considering I'm using the same settings. Ultimately, I need to run P-95 to figure it all out.

Overall, this cpu seems to be scaling with voltage. Temps at 8x450 ranged from 45-55 C under P-95 Blend. 55 C was hit on occasion, with 48-50 more the average for all 4 cores. I was running my rad fans on 12V to help keep temps down. Still air cooling the NB. Running the stock fan on 85% duty cycle, NB temps stayed ~45-47 C. The machine sounds like a hoover at this point! I can run things much quieter under 24/7 use. The stress tests really hammer temps.

Ok not trying to tell you that your overclocking is easy but 3.6ghz on a Q6600 G0.... that's like a walk in the park....

3.8 is actually easy for me aswell...

now 4.0ghz on air would be impressive.

So either i don't understand this thread or you should try harder :P

Sailindawg

11-08-2008, 05:08 PM

Thanks for the encouragement! I'm a lazy overclocker taking my time to see where I can go with this board and chip. I well understand that 45 nm is the way to go, but that's not what I've got. This is my first 775 board and I'm enjoying what it can do. I suppose that I could just up the volts and see where I land, then work backwards to see what's stable at the min volts. I guess the point of the thread is that I'm enjoying the board. :D

thats what it's all about :up:
not every thread has to be "I got a problum" thread :D

get it to 4.0 and go upstairs :up:

good steady work man keep it up my first hitting 4.0 on a pent "D" was quite the rush :D

Catz

11-09-2008, 05:06 AM

alright sweet, i wish you all the luck :D

Didn't quite understand the thread ;)

4.2ghz is my max on the Q6600! Have fun :up:

@Rem

No problem dah-lin' :toast:.........I'm chasing 3.8 at the moment :up:......at 1.6V on the northbridge, I'm getting to the limits of my NB cooling. I'm hitting 50C on the NB. Not bad, but from what I've read >50C not so good! I'll give 4.0 a go sooner or later! :D

What were your settings? What Vdimm did you use? If I use any other divider than 1:3 or 1:3.2, the board will not post.

@Ryan

That's the crazy thing with these RAM chips. I'm only using 1.84 Vdimm. I'm really able to run them tight at stock FSB for the RAM. If I try to run them on auto, which seems like 1:1, the board will not post. I have tried the different straps, same thing. Once I got above 400, 1:3 divider seems to work real well. The old run the ram on a divider and go for really tight timings.

nice oc, what ur highest fsb? i cant break 469, good luck with 4GHz+

So far, 450. :D And thanks :up: I'm working on 4 as I type this. So far WPrime stable, now to work on ITB & P-95.

Edit:
I have been trying for the holy grail of 4G. I can boot to it, run 3DMark 2001, pass WPrime 1024 run and play some COD4 single player. But the minute I try P-95 or ITB, it reboots. The voltages are really starting to get toasty as well! I need about 1.63V to boot into windows. Maybe time to try a different BIOS.

11-15-2008, 08:04 AM

I'll make thread about settings and other,cause I have a few very nice score... 4gb,quad,e8600,all tested on this board...

Very cool Quake. I'll look forward to seeing what you have. Regarding the hunt for the mighty 4GB, I have finally gotten P-95 small fft's to run for about 15 minutes without failing. I stopped P-95 after 15 minutes. Volts were getting very high. I posted in another thread regarding running Q6600's over 1.6 volts. That thread is here. (http://www.xtremesystems.org/forums/showthread.php?t=207538) Quick read, but the people achieving 4G on a Q6600 were using over 1.6V like I have found out. Thasp had an interesting post in that thread regarding Q6600's and their durability at high volts. I remember Thasp from the DFI-Street days. He put up a lot of good posts showing some very good clocks.

My settings for my most recent 4G foray were as follows:

1.63 Vcore, V-droop enabled
VTT =1.5 GTL +12 (all)
PLL=1.622V
NB=1.62, GTL -8
SB=1.538
RAM=6-6-6-18, CR=2N, 1:3 divider

Running the RAM at 2N seemed to help a lot. I also changed the cpu clock skew to 200 ps. That seemed to help stability as well. I ought to go back and explore some more.

One thing I really like about this BlackOps board is the overclock recovery. One always recovers right back after a no post with overzealous settings.

@HDChopper

lol......thanks! :toast: Being able to boot to 4 was pretty cool, but watching the small fft's finally prime away for a bit was very cool! These 65 nm SLACR GO's seem to really scale with voltage.

Hey Sailindawg,

I just got myself a Blackops which makes it blackops/q6600 combo.

I was wondering if you can be so kind to post clear stable settings for 3.2-3.6 oc if possible, my rig is:

Intel Core 2 Quad Q6600 2.40 GHZ G0
Corsair H50(watercooling)
foxconn blackops x48
G.Skill Ripjaw 4GB DDR3 1600MHz
Sapphire VAPOR-X HD 4890 1 GB
Microsoft Windows Vista Home Premium SP1 32-BIT
OCZ 600W Stealth XStream - Low Noise

Thanks

Each overclock is different and needs different settings to be stable. What works for someone else wont work for you.

You need to start from scratch yourself

Spork!

10-01-2009, 06:26 PM

Having some mixed success atm
can do 415 fsb no probs.
Passes 10 x LinX @ max. memory used.
Passes 3 hours Prime blend test.
Freezes after a couple minutes playing Mount and Blade.
Any ideas?

That was with a x 8 multi for 3.3. drop back to 400 x 8 for 3.2 and game runs fine. Currently testing / tweaking 400 x 9 - 3.6. Can run Vantage, currently priming, but errors (and v. hot!!!) on LinX. with (only) 1.3875v.
What is the maximum safe core temp for these chips?
I think I'll need 1.4** vCore, but don't want to fry it, although I have megahalems and I have seen other ppl. stating they have had 3.6 or higher, with way more vCore, on air...

Yes it does work like that, I agree that you will have to make adjustments but overall copying settings works...I did same with my previous motherboard and it work perfectly

Got a solid 3.6 @ 1.3875 vCore.
LinX temps are a bit high for comfort, but mid 50's with normal use (gaming). :)

well at present I have: 400 x 9
1.3875 vCore
1:3.2 memory divider
vDroop compensation enabled
GTL Ref 0 - 3 Voltages all +1
NB 1.312v
SB 1.575v
dram 1.801v

works for me, solid as a rock, but v hot on LinX, not too bad under "normal" use.

Good luck and have fun.
If these setting screw any of your stuff please don't blame me... :shocked:

edit:
wonder where he ^^^ went...
got mine @ 3.75, 1.4v now, passes every test - except LinX where I get errors. Not willing to give it any more juice on air cooling - too hot already. I think 4+ would be fairly easy with water, but I really don't need more than 3.2... Looks like 3.6 will be my 24/7 setting.
/me loves my Blackops. :)
