Gigabyte P35-DQ6... 500MHz FSB NO PROBLEM! + dual 32M 603MHz 4-4-4-5 RAM STABLE!

Nice!!

I want to get this motherboard for a new Intel Core 2 Extreme QX6850-sample I got this week, but unsure about how my Tuniq Tower will fit. You wrote that it almost fits. Can you elaborate on almost? Please?

This is so you dont have to manually use jumpers or a slot card (like on nvidia 650i) to configure SLI/Crossfire.


I am still testing the board, but I hit a firm WALL at ~525. Not really sure what is causing it. On the P5k deluxe, same wall is ~535.

It could be the CPU, but this same CPU I was able to do 550 on ASUS commando. I will try other CPU's later such as E4300 and E6420.

I always assumed there were the dual bios, what are the Amtel chips i see on the board?

I noticed the plastic caps myself but didn't think much of them...in that i didn't know what function they served. The heat generated from the various heatpipes seems much cooler the my P965-DQ6...add to that the nature of the heatpipes means one of them is close to a fan which is sucking air/heat from the heatpipe.

Here's a SuperPI run i did, see sig for settings. Memory is running 1:1 with 4-4-4-12-2T timings, 2.0V

425x8, Vcore set to 1.400V. (G)MCH and FSB set to Auto, PCI-E frequnecy set to Auto.
I ran all the SuperPi tests....is 15m 51s good or bad?

Irev...can you also confirm the quirk i noted in Q-Flash..as in only one 1MB bios chip being listed and lack of being able to flash the backup bios?

I know GB say this a safety/design feature...just want indepedent confirmation.
Also...have you noticed they have gone back to using the slower STT flash parts?...the P965-DQ6 used different flash bios and the flashing process went much faster.

Some more tests, Latest build of Everest, and some HD Tach results using a 32K stripe, RAID 0, did a quick and long benchmark, then i installed Intel Matrix Storage Manger 7.5 and enable writeback cache.

Everest, i don't have a full version :(

So it has real dual 8x slots? Or 16x+4x like the P965?

Why does this keep on resetting back to stock when I try to overclock. Same problem as before with the DS3.:mad: POS GB. How come this won't go past 426x8 even when it is set to 438x8 in the bios?

I am at a loss to explain also, it's either the CPU or memory...people have suggested a CPU will only reach a certain FSB, some porcesors get to a higher FSB then others.

Anything past 448FSB and my bios disables the overclock. I have tried a 6x and 7x multi.

No, it's 16x + 4x electrically, if you use the second PCI-E slot as in add a second graphics card then the three PCI-E 1x slots won't work/disabled.

probably because your OC is failing. P35 seems to do a much better job of reverting from a failed overclock than 965.

Both P5K and P35-DQ6 seem to share the same ability to recover!

I agree with that, the bios is better at a fialed OC, it'll try 3/4 times then disabled the OC in bios.

It is failing at certain CPU clocks. I tried 438mhz and it failed but at 444mhz it booted up just fine. Does that sound right? Say if I tried 486x7 then would need to increase the CPU voltage? It is 1.45v now. I can get the memory up to 533 5,5,5,15 no problem. Also is there anyway I can increase the memory performance as it seems lower than my BX2.

Thanks for the Tuniq pics. Seems its "good enough".

I think the squealing comes from coils, someone maybe able to answer better. To me, this board is dead quiet, but I wouldnt know until I put a quad core with 1.5Vcore+



The key is the fact that they are clamped with screws, not push-pins. I think this helps in a HUGE way.

Those plastic skirts are for support and aligment purpose. The caps on this board are surface mounted and not thru mounted. Thats why those skirts are necessary to ensure the caps sit vertically on the board and not tilted or misaligned.

FYI, surface mount means that the contact legs of the device (can be caps, chips etc) are soldered directly onto the surface of the circuit board. The tiny resistors and ICs used on this board are surface mounted.

Thru mount means the contact legs goes thru the circuit board and is soldered on the opposite side. The inductor coils (those black square boxes)are such examples.

I think I figured it out after a failed overclock. If it fails for me resets to original clocks I had before like 444mhz on the boot up screen. All I did was completely kill the power to the motherboard by moving the selector on the PSU and turn it back on 5 seconds later and this is what happened. I did this twice and it seems to work so far. Very odd indeed.:shrug:

Here are my results so far on the DS4:

I have been in windows at 640 mhz on the ram but wasnt stable.
Dont think my cpu will do anymore.

can you run the memory asynchronous like RD600?

So how did you get 500FSB?...as in what bios options did you enable/disable?

As far as i know running 1:1 is faster.

Just 500 FSB and "2.40" in the multiplier setting.
The options in the multiplier just dont make any sense to me

it means that you can overclock CPU without overclocking memory...

So (G)MCH/FSB and PCI-E voltages are set to Auto?
Have you left PCI-E frequency set too Auto or 100?
DLL RAM setting to Option 1 or 2?

What's your DDR2 voltage set at?, what brand of memory are you using?
I'm starting to think the G.SKILL HZ won't allow anything past 450FSB.
