---------- Quad Overclock Thread! ----------

[ChronoReverse]

Eh, my board seems to run happy at 450FSB without raising voltages. I'm more surprised that other P35 boards (mine is a DS3P) can't manage that at the midrange and up.

I don't even have that great of case airflow and I hear people talk about 6 (rather noisy and high flow) case fans having trouble with cooling. It's incredibly incongruent to my experience.

It could probably do 3.6 @ 1.6 but my motherboard won't provide it after vdrop. It would be too hot anway. That's what you get with a 1.325 VID. I'm still happy with it though.

im sorry but do you know how to oc?

1.5V on a ultima90? You asking for a hardware failure in a few months? Because your cpu will die at that voltage unless your on water.

My Q6600 does 3737@ 1.44

My B3 Q6600 did 3.6ghz @ 1.5Vcore <--- WATER


Rule of thumb. Ultra120 > Ultima90

Max safe voltage for Ultra120 ~ 1.45Vcore. Anything more and your asking for it.

Your doing something very wrong to be pushing that much voltage on that chip.

 

[ChronoReverse]

Don't actually use the HSF as your point of reference. Use the actual temperature. If somehow your ambient is quite low and you can keep below 71 even on load then you're fine.

With that said, it's highly unlikely you'd be able to maintain 1.5V at reasonable temperatures with the 90 unless you have an air conditioned room.


As for voltages. Intel design specifications state that the maximum voltage for the Core 2's is 1.5V. Even so, it will be very difficult to keep the temperatures under control.

have you seen how hot these girls get at 1.5V??

His room would need to be in a meat locker to keep that under control even with a TR120Extreme

Im with aigo on this one, however im running an early B3 which is the worst case scenario.

I can hit 50C loads with high end water.

 

[ChronoReverse]

Since he already has a -90 then it doesn't matter as long as his temps are under control. It's unlikely but it's still the final say rather than any guidelines.

That's all I meant and you don't need to try to read more into it.

Ok I'm working on Prime 95 stable.

It's stable at 3645 Mhz,

I will try and get Prime95 stable closer to the 4Ghz, but I finally believe my PSU
is blocking me since it's 12v rails aren't giving me the Amps I require AAAARGH!.

IT has 1 dedicated rail @ 18 Amps for the cpu, and per the psu's literature it peaks at 23 Amps MAX.

And at 4Ghz my Q6600 requires 28 Amps min.

Here is a link to the mini test I did @ 3645 in Prime 95

http://www.molevee.com/BenchMa...stable%20at%203645.png


I will eventually run Prime95 overnight at 3645, and post the proof.

But now I got to try increasing the FSB even more!

My northbridge is watercooled, im hard limited to about 455 fsb regardless of voltages.

No change from default to +.3V vFSB and Northbridge.

Itll post and go all the way into windows at 500+ fsb, but 2 of the cores vanish into thin air.

uhhhhh what are your ambients? 1.53V on a Q6600 on AIR???

You sure your chip aint throttling somewhere down the line?

What bios version are you running with your P5K-DLX?

u know i forgot. i havent shut off my comp in a few weeks now.

lemme finish the last min quarum on WCG and i'll reboot and tell you

heh how you liking that board mark?

im debating on either skull trail of the X38 DQ6 ATM

 

[Markfw]

The DQ6 rocks, but newegg doesn't even have it or the gigabyte site ! Mwave still has it though. Too bad, its the best motherboard I ever bought !. NO vdroop.

 

[BrianDickens]

QX6850 - 3.66ghz (11x333) on 1.4625V (will try lower eventually, this voltage is still a result of previous overclocking attempts)
Cooled by Thermalright Ultra 120 Extreme with a Scythe SFF21F fan at full speed
Motherboard: Gigabyte GA-X38-DQ6

Running BOINC/Seti@Home for three days now. Temp @ stressed is about 62C on average (using CoreTemp). I'll try to reach 4 ghz later on next week, would be cool if I could reach it with the system remaining stable.


BTW: I finally dropped trying to overclock using the FSB, somehow that gave me various troubles with stability - even if I did raise FSB voltage. Memory wasn't the problem either - it's PC7200 DDR2 RAM from OCZ, which I have running at 2.2V and I always kept them at or below their maximum frequency.

This is my preliminary OC - I have not tried to find the limits of the system.

Gigabyte P35-DS3

It's currently temp limited in Prime95 stability, because the P182 isn't cool enough, because my HSF isn't lapped, and because of the stock TIM.
Folding 100% stable though, as well as everything else I do with it, Team Fortress 2 and other games. It's on 24/7 and hasn't crashed yet, so this is my daily overclock.

I'm going for 420x9 once I get a P5k Deluxe/Premium, change my case to a Lian-Li A70b, and lap the Ultra-120 + using AS5. Will post results soon

Seriously? So why is there a vdroop mod out for the DQ6? o.o

I'm looking for a new motherboard now and can't decide between the P5k deluxe and premium, and now the DQ6 might be a good idea. Arghhhhh

Now it'll fail Prime95 after about 2 hours, however its stable for gaming and heavy load otherwise. Even Crysis for hours on end stable.
