I gotta ask what your other votlages are to the guys who are posting 3.4ghz+ with low volts. I can't get my quad to 3.4 without some crazy voltage. To get to 3.6ghz it needs at LEAST 1.50v in bios. Thats around 1.46v real under load. What are you cpu vtt and mch voltages?
I also can't drop down the vcore even if I drop downt he multi. Gotta keept ehs ame vcore to be stable at the same fsb. What in the world am I doing wrong? My quad is a L724A760.
What are you doing with your NB and SB voltages - Your description sounds very much like you need more NB volts and it would never hurt to throw a fan on it too.Quote:

My SB is only at 1.10v from 1.05v. Do I need to ramp up the SB in order to be able to get a lower vcore?
I have just bought a Q6600 g0 but I do not be able overclocked to but of 3ghz, not itself if be the motherboad.
the temps are very well, i have a lapped TR 120 Ultra xtreme.
my motherboard its a Asus p5w dh deluxe
It's certainly worth trying, although from your original post it sounded more like a NB issue. What ratio/volts is the ram on and can you slow it down to take that variable out of the picture?Quote:

It could be - from your replies it doesn't look like you're doing anything anything obviously wrong - If there's nothing else then it may be just a bum board.Quote:

Ok so ive ready through most of the posts and am still not convinced that G0 is any better than B3...still I went ahead and bought a Q6600 SACR G0 today to compare them.
My B3 maxed out on SS at 4.3ghz... http://valid.x86-secret.com/show_oc.php?id=224147
and does 63c 4 cores folding on air at 3.3ghz and 1.40vCore hopefully the G0 will be better...
Here's one of mine ...... Small FFT's. Yet to try lower vcore.

Simple watercooling on P5K-DLX :)
Anybody have an L721A814 stepping?
How's it clocking for you? I think my XBX2 is the limiting factor in my overclock. I sure hope I didn't get a bum stepping. Seems to be my luck, though.
My second tank guys G0 arrived today. It is the exact same batch as my first tank guys G0. L724A760. Both do the exact same (3700mhz 1.45v) on my EVGA 680i. Same temps and all. Identical twins!!!! :)
How many B3's have you seen @ 3600-4000mhz on air? Not only do they OC better, they are a lot cooler. Some people don't believe that they are actually cooler, they think it's an issue that needs to be addressed with core temp or whatever. Some people say ad 15c to the temps and that would be the correct temp. My radiator fans are blowing towards me and i can tell you the G0's are cooler. With my B3 the air was so warm it was hard to even sit next to it. With the G0 i hardly notice the air.Quote:

I think I may be at the board limit - This is one of the original first edition P5B DLX's and it already has some "bending" issues when tightening the evap (I have to get it JUST right or it won't post) so I guess it's time for a P5K.Quote:

at first i thought it was the board, now i think it might be the chip?
all i know is not everyone that gets/has a GO is hitting 3.6 and above on air.
Mine's a L723A890 - seems ok so far, I'm certainly not disappointed yet.Quote:

This is using a Scythe Infinity with 2x120mm fans in push/pull config. @ 1.4v the max temp is 64C under prime load. I guess i need to look into Scythe mounting mod. I'm currently using the crappy standard 775 socket retention push pin's that came with it. This weekend i will go to the hardware store to get what i need for the bolt through method.Quote:

I don't think lapping is going to net significantly lower temps on these as i can tell you that the IHS on these appear to be very flat. I did the razor blade test on mine before installing and it was indeed flat.Quote:

yeah, you have it under vapochill...i would be lovin life if mine was hitting 4 Mhz.Quote:

thats what im talking bout!
me...i need 1.4 just to be doing my measly 3.2.... on water no less....:(

723A825 here, pretty decent chip. Not all are golden, just most that post have higher clocks. Nobody want to say they can't hit 3.6 :lol: My ihs was very flat also, and I'm cooling with a lapped ultra extreme. Been running f@h for 3-4 days now. Temps are 47-55c, ambient around 70f.Quote:

i've gotten my cpu to prime at 3.5GHZ, but my temps started running away to like 90°C after like 5 mins.. they were kinda constant for the first 3-4 mins, then started to take off, so i shut it down. i think heat is my main problem keeping me from going over 3.4ghz.
edit: i'm gonna run another 8+ hr session of prime, so i'll see if my temps dropped any (although i haven't really turned my pc off much so the AS5 sets correctly). I'm just checking to see if it's stable with C1E enabled so i can save some power...lol
