Is

333x9 (3Ghz) @ 1.225V for 24/7 stable OC any good?

Quite happy with that speed for the mo until i get better fans for my Thermalright 120EX so wanted to lower volts/heat as much could for time being.

Vid 1.3125V

[KTE]

Psycho_eddie Have you tried 3.2G at those volts? (temps)

Whats your load voltage? Mines lower VID than yours but 3.2G 1.2V is about tops stable. Benchable is higher but that doesnt bother me. Bloody temps, mine will freeze at 74C, heh.

[S1mon-]

thanks simon loads temps look a lil high what are you using to cool that?

also awesome chip bei fei!!!!

i found a L739B897 is this batch any good?

cheers

I'm using a Thermalright Ultra-120 NON-eXtreme with a 1500RPM fan. The temperature may be a little high but my room temp are always a lil high... I would say 23-25 degrees...

[S1mon-]

Never saw this before for some reason but thanks S1mon. That's very good actually.
Idle Vcc will be near the 1.312V mark?

Those temps are exact same as mine at 3405MHz 1.312V 5hrs P95 with only one fan Zalman 9700 with 6C higher case ambient than yours. 1.28V gets a little lower temps stable.

There's a problem with my setup. Whatever Vcc above 1.28V I set in BIOS, it keeps dropping to 1.28V under load, 1.3, 1.32, 134, 1.385. That didn't happen with the E6750/E6850 I tried last. 3.45G is around max stable with 1.28V idle/1.264V load, more MHz and Core3 will fail instantly whilst the others don't till at least 3.605G that I tested. But volts for 3.6G stable seem high, maybe past 1.4V actual. I'll try it soon but I'm scared of the crappy temps and power I'm expecting.

Idle vCore is 1,296V and Full vCore is 1,288V using "Loadline control Enable" on my Maximus

Q6600 OC Problems
For the life of me I can't get it to run at 400x9 1:1, the best I can do is about a minute or two before I get a BSOD vista.

The best stable I'm able to do is 435x8 @ 1.45v under water, and it runs a bit hot.

I've tried dozens of configurations found in this forum, I've mucked with just about everything. I'm suspecting some sort of memory problem because I'm running 4x2gb DDR2800.

I have a G0 L373A.

The rest of my rig:
P5K Premium
8GB G.Skill DDR800
EVGA 8800GT

[scorpion]

anyone know how the L721A814 batch fair.

[scorpion]

you should be able to get 3.6 with no pro, what are your vcore,mch,

what are your BIOS settings and what temps do you call a bit hot idle and load?

[Eldonko]

Put your mem at 1:1 or loosen the timings to rule that out. Most G0 will do 400x9 no prob.

[KTE]

Here's what mine did max on air, 17C ambient, Zalman 9700 (bad)

what batch is that ^^^^^

L739A554 (11/21/07 pack date) 1.2375VID 1.20V stock.

http://valid.x86-secret.com/show_oc.php?id=301096


Benched upto 4.2GHz, 4.25G 1M should be fine (don't care about it).
Around 10MHz more was attainable but never saved it before I went higher and haven't tried again. 1.65V real will get 4.3G bootup easily but I can't risk the chip and by that time my PSU OVP kicks in and shuts down the system.

Max FSB with 1.472V was 496: http://valid.x86-secret.com/show_oc.php?id=301088

Actually it'll be 498FSB but I was lazy as usual.

Power draw/heat is too much for me to try more than 1.36V, ever. And everything passes +3hrs P95 (that I tested) at 1.30V for 3.6G but core3. It fails even at 1.328V, only 1.344V load will stabilize it fully and which means 1.360V idle.

1.28V benches 3.6G easily and 1.392V benches 3.84G and 4GHz easily that I tried. Stability definitely requires more than my cooling capability.

Just for everyones reference; it's good to know some solid tested facts

With this chip I need (all I've properly tested thus far - my full stability stated means sub 65C >8hr P95 load temps, videoing, gaming with just the 1 HS fan and >22C heatsink ambient):

MHz - BIOS/IDLE/LOAD (V)

3405 - 1.300V/1.280V/1.264V (fully stable)
3438 - 1.322V/1.312V/1.28V (fully stable)
3600 - 1.350V/1.328V/1.312V (fully benchable)
3600 - 1.362V/1.344V/1.312V (3 stable but core3 fails >3hrs)
3600 - 1.36875V/1.360V/1.328V (as above)
3600 - 1.372V/1.360V/1.3287V (fully stable)

3840 - 1.450V/1.392V/1.372V (fully benchable)
4050 - 1.468V/1.392V/1.378V (fully benchable)
4225 - 1.580V/1.472V/1.4365V (short benchable - not verified 3D)
4270 - 1.650V/1.600V/1.558V (short benchable - not tested much)

what batch is that ^^^^^

[Controll3d]

Currently running this Q6600 (G0) @ 3312MHz, 368FSB and needs atleast 1.31-1.32V (1.340V @ bios) to work on these speeds.
With stock volts it barelly hit 3GHz barrier and FSB wouldn't go even over 350 (BSOD @ boot).

I do know having 4 memory sticks doesn't atleast help this matter. "Bad" chip (like always) that needs alot more Vcore to work higher speeds.
Which causes bit of issue with temps. 43/43/38/42 usual idle temps and load temps goes way over 50°C already.

Current case cooling needs improving and Zalman ain't exactly best cooler either. Case coolers are still original Antec's that came with P180, but gonna replace them something better and more silent soon.
It was even worst with old case...

Wanna push it bit higher than currently and i know these Corsair sticks can do atleast 442 (running 1:1.2/5:6 even now). System is running 24/7 and looking for max 24/7 stable speed can get.

[chew*]

/\ pull 2 of the 4 sticks out then retry.................also dont be afraid to bring FBST up to 1.50 and NB voltage to 1.50.......

[chew*]

Also just a little tip........its always a good thing to follow this procedure.......

Drop cpu multiplier, drop ram via divider both below stock speed.......max the FSB on the board with prime and fine tuned voltage adjustments (less is more) till your at least 12 hours stable.

Next bring your CPU up.......find its max as well same method......

Drop cpu multi again and find the max of your ram via the same methods.......

With voltage imho less is more.......No sense in cranking the voltage up, fine tune it, get it stable with the least amount possible......

Once you've done all that put it all together.

[Counter CS]

Well, hi.

I have to choose btw Q6600 G0

L739A and L734A

Witch one ?

Looks like all the new E8x00 serie was added to next mounth... Intel is playing with us now.

[WizardofOz]

thanks simon loads temps look a lil high what are you using to cool that?

also awesome chip bei fei!!!!

i found a L739B897 is this batch any good?

cheers

Here are some folks with a L739BXXX

1. L739B250 1.30v VID 1.774v to do 4.2GHz http://www.xtremesystems.org/forums/...152603&page=69

2. Darkstormz has a L739B you may want to message him http://www.xtremesystems.org/forums/...152603&page=70

3. L739B770 has 3GHz and no other detail http://www.evga.com/forums/tm.asp?m=174720&mpage=6&key=

[lefy]

are some batches just hit and miss? i have L726A and i can't get anything beyond 3.2GHz prime95 stable. searching around here i see some people saying this is a great batch, and i also see other people with crappy oc's like mine.

i started on a 680i and wasn't sure if it was me or my motherboard. now on abit ip35 pro... i can definitely get windows to boot at all kinds of clocks that wouldn't even POST on the 680i, and my temps are a lot better, but i still can't get anything stable beyone 3.2 on either chipset

my VID is 1.3000

[atlxkevinx]

For people who hit 4.0ghz.. does it require any voltage upping besides the vcore? MCH? CPU VVT?

What vcore do most people use to obtain the 4.0ghz OC? I am in the process of trying to break the big 4

Maybe, not always though. If someone with better cooling had my chip, they could hit 4GHz stable with 1.49V.

I tried it briefly but whilst I experienced no freeze/lockup/reboot in running benchmarks, the problem was temperatures and power draw: I'm not going to accept something that ridiculous, it even topped 30W above my PSU rated max wattage.

I need +0.175V MCH and +0.2V FSB and 1.39V VCore for 4GHz bootup. That's fully benchable without error but not stable, need much more VCore for stability but on a better board, it won't do because on my MB 1.392V BIOS is 1.372V idle OS and 1.344V load, which is what screws everything up.

Q6600 L737B064

With just cold ambients, all inside my case (18ºC) I can do this:





This Q6600 + DQ6 has a FSB wall around 470Mhz. This same Q6600 can prime @ 510Mhz FSB on P5E3

Max stable 3dmark (X38-DQ6's fsb wall hold me back):
Note: C1E activated



This CPU is a beast. I can run 3dmark06 at this setting with only 1.58v, but sometimes it would crash on CPU test. The sad part is when I discovered that this mobo has bigger Vcore intervals after 1.60v. A pic to make you understand:



Well, I'm happy with this piece of hardware

Rbs.


PS: P5K Deluxe will never do that. Max 3dmark06 stable was 4050Mhz at same conditions.

hi guys, i need a little information, anyone here has an L737B121 or seen this and knows whiwh VID it has?

thank you in advance

[Controll3d]

/\ pull 2 of the 4 sticks out then retry.................also dont be afraid to bring FBST up to 1.50 and NB voltage to 1.50.......

Might try with 2 sticks sometime soon.
Bought these sticks with mobo and CPU, but also looking 2x 2GB kits now. Seems to be getting just cheaper everyday.

Voltages set atm:
Vcore = 1.32V (1.3400V @ BIOS/µGuru)
MCH 1.25V = 1.29V
ICHIO 1.5V = 1.55V
CPU VTT = 1.23V
ICH 1.05V = 1.09V

Upped FSB bit, 3330MHz (370x9) now... mems running 444MHz (5:6).
Almost ordered Noctua NH-U12P cooler. It's just bit.. expensive.

Also forgot to mention earlier. It's L739B300, 1.250V VID, Pack date: 11/22/07

Just a data-point... I just purchased an OEM Q6600 G0 from Newegg and it came up as:

L733B - 1.25vid

...so far, I haven't seen anyone post results for this week yet. I don't have my system together yet, but will post some results once I do.
