You may try some more MCH voltage if you want to keep tighter ram timings

[ckirkby3]

I dont know if this has been answered before but i really need help. I removed the crazy cool heatpipe system replaced the north and southbridge with hr-05's (thermalright heatsinks) but it left my pwms with no cooler. So i butchered the crazy cool system and crimped the heatpipes of the mosfet section and reinstalled just that part. But it doesnt mount properly its a bit wobbly. And im sure someone from you many dq6 users is using an aftermarket cooling set up. Surely? Im sure this is the bottleneck of my overclock as it just doesnt seem as stable as it should be. Hope someone can help?

try looser ram timings. to get up to 4.6 i needed 1.575 in bios (1.52 actual) so you may acutally need a bit more voltage. If your on water I wouldnt worry about putting bios setting a little above 1.5 (up to 1.55 max for 24/7 i would say)

Yeah, not sure what the problem is

I tried going higher on the NB, nothing. And i tried the ram timings at 5-5-5-15

I guess it could be the ram. Its not exactly "high end" stuff

[ThatGuy16]

I was thinking, could the NB getting too hot cause that? Right now at my 24/7 clocks, on idle, the NB heatsink feels hot to the touch.

I have already tried the hr-09 type2's as recommended on thermalrights website but they are too wide and do not fit without damaging the surrounding components. Can someone please advise on other options????

It is possible.. My nb used to get very hot, now I put a 80mm fan over it, mounted to the screws of my backplate.. http://home.comcast.net/~typhoon007/mod3.jpg

If you are using a backplate it is extremely easy to do, just need to buy some longer screws .

[ckirkby3]

Make sure the northbridge heatsink is mounted properly and the thermal adhesive is making correct contact. Or try replacing it with some decent thermal interface material (heatsink paste) or try replacing it with a decent heatsink itself? Like the hr-05

[ckirkby3]

Again can someone please help me with my aforementioned problem lol. Im losing the will to live haha

Cool, i might get a little smaller fan and stick it on it

The stock NB heatsink moves really easy, every time when i'm installing something, if i bump it, its "slides" up or down..

But its using those spring loaded screws, and it must be making good contact or else the heatsink wouldn't be hot

F9a for x38-dq6 is out

They seem to have made changes to the memory system. TRD also actually seems to calculate a little better finally. 2.4B strap seems to be back in F3-ish shape. Interested to see how you all like it.

[ThatGuy16]

I'm still stuck, and can't hardly get into windows with anything above 480FSB. I'm using the original F1 bios, would updating to F2 possibly help?

I want to clock this baby higher!

[zicada]

Youre kidding right ?

F1 ?!

And why got to F2 ?

All pieces of software mature over time. Probably houndrets of bugfixes between F1 and F8

Update directly to F8,- really!

NOOOOO!!!
H e has to step up through them.. He can't just jump to f8 man , bad advice.

[truehighroller]

On a side note isn't the 2.66d a better setting then say the 2.40b setting in the memory timing options? I have seen a few post making it sound like the 2.40b is better?

[road-runner]

Any one know exactly what these setting do? I am having trouble getting the QX9650 Prime stable at 4.00Ghz, specs in my sig...

CPU/PCIEX Clock Driving Control
CPU Clock Skew Control
(G)MCH Clock Skew Control
MCH Reference Voltage Control
DDR Reference Voltage Voltage Control
DDR Termination Voltage Control
CPUGTLREF1 Voltage Ratio
CPUGTLREF2 Voltage Ratio

Hi there. I do not have the exact same board, but cooling the NB really did the trick in my case. I clocked the e8400 to 4,5 Ghz stable, but to be honest, the voltage I had to put in the cpu for that was too hight for a 45nm cpu to live longer than a few game sessions (about 1.525...). So if I were you, I'd get a decent NB cooling (or build one myself out of a CPU cooler) and then rise the NB voltage to the max, or, as I do not know your bios, to +0.25 for starters (I give'im +0.30), and do the same to the MHC voltage. In the end I would wonder what for exactly I needed 4.5 Ghz...but anyway. I see you have 3870'ers in CF too, and with the sig below, believe me, you're able to play the most demanding games of today with >35 fps. So...be gentle with that poor little bugger

i have the X38-DS4. There are only 3 bios for it, F1-F3

I'll try cooling the NB with a small fan

please

for me, 2.40B worked great with the G.SKILL's PC8000, but the 2.66D works better with the PC8500 models.

Richard Dower must be getting a little sloppy, thanks fir the heads up.

It seems the bios for the X38 and X48 are identical , they released an x48 bios today as well with exactly the same changes haha.

Right but, which is actually faster though? I thought that the 400 strap would be faster snappier you know what I mean?

Wow this is a long thread....I started reading but wonder if you guys help me with some questions: I have EX38-DS4 and Q9450. The board comes with F2 bios. The RAM is CORSAIR Dominator PC2 8500. I was able to run 440FSB. I then updated the bios to F3 and ran at 444FSB. I did not change any voltage. I did change the speed of RAM to make sure it wasn't over 1000mhz (sorry I forgot the exact speed). This morning I tried 446 it couldn't boot. Now it can't even boot to windows at 406FSB. Anything over 410 FSB and the pc just keeps restarts and resets the bios to defaults. Any idea what is wrong? I already cleared the CMOS a couple of times.

Also anyone knows why when I click on the "Turn off computer", the "Stand By" option is disabled? This is on XP

Another question is that on the Abit IP35 Pro, I can set the fan speed according to the temperature of the CPU. How can we do this on this board?

Also if someone can share their settings, I would appreciate it. I understand every setup is different but want to get some ideas

Thanks for your help everyone

i recon they are identical save for a few things.

Go into power management for XP, or you might need to update your graphics drivers. For the fan go into PC health...the fan speed settings should already be set to Auto, unless you're not using a 4pin PWM fan.
