Does anyone have this motherboard and if so, I have a qx9650 and i need help with bios settings. There are way to many and I dont have a clue as to what some of them mean. I am trying to get a stable o/c, all I can do is 4.3ghz with 1.52v never goes over 65c b/c I just bought a Swiftech H20-220 compact and it seems to be doing the job but I cant get a stable configuration to go past 4.3ghz. I need bios settings and system tweaks. memory is gskill pc2-8000 so going over a 420mhz fsb is killing me. Maybe you guys know something I dont. Thanks for the replys.

Just *how* high is that FSB!?!? :eek:

Regarding your memory: You should be able to get the FSB significantly higher than that on a DFI board. So if your RAM is stopping you, set the memory divider so your RAM is UNDER~clocked. That will give you the headroom you need to raise your buss and work on your CPU. Once you have your CPU stable at it's target, *then* you can go back and tweak the RAM.

The order I would approach it is: (1) FSB (2) CPU Multi, and (3) Memory Work on only one thing at a time, and I think you'll find far fewer headaches.
 
You are getting 4.3Ghz from a 2.66Ghz processor? Seems like a pretty hefty overclock already. But, your memory is probably the biggest problem.

What Scotteq said.

Read you manual, very closely. All those settings on your DFI board will allow you to do some pretty big stuff, but you have to know what they all do.

My memory is not holding me back. On evongugg, where do i look on that list of things, thanks, I have read the manual but it is chineese to me. LOL
 
Steeda - You should be able to get to a 500 (2000)Mhz Front Side Buss on that mother board with little trouble. But what happens is when you raise Front Side Buss speeds, it takes the memory along with it. You can do a 30~40% overclock on many CPUs. But memory?? Don't count on it. Not at all. I suggest you revisit your Memory Divider.

i know, do u think i did something wrong, looked at the cpu and the thermal paste looks good, do u think I tighten it down to tight

Splendid


Agreed. I get a stable 4.1ghz on air with a TRUE on my QX9650 and the temp only goes to 48c loaded up on Prime95. By the way, that Swiftech compact cooler is not designed for heavy duty use. As far as the FSB problem goes, many motherboard exhibit "dead zones" which won't work regardless of what you do. A way around them is to use a lower multiplier and then a higher FSB.

As far as the ram goes, don't know what voltage you have it at, but 2.1v-2.2v seems to be common for higher overclocks. Balancing the ram divider is also a bit of a guessing game, as you bump it around in search of what works. Be aware that any ram clocked faster than DDR2-800 is overclocked ram, so what you're searching for is a sable overclock on the ram and not every set will go to the very high clocks.

True, I here you on that, but getting back to my temps, do u think I did something wrong, b/c I am getting around the same temps with my tuniq tower except they are a little lower. Any advice?

Ok, i am running prime95 right now on it, 56c @ 1.18v shouldnt my temps be at like 40c with water cooling? Another note, my temps are always at 55c when i startup, sholdnt they be lower?

I have an antec tri-cool fan and it has a 12v attachment but i have it to my motherboard as well, have had my computer for 30minutes on everest stress test at 4.3ghz at 70c at 1.46v 1.51v in bios

As long as it's stable, the 70C is a bit high for my taste but I hate to see 50C on my Q6600.
If you need better performance look into the D-Tek Fuzion Waterblock and a Laing DDC pump (expensive DIY but no other way to get better performance).

1.5v seems like alot for a 45nm processor. I know it's a quad and it'll need a little more, but it still seems like alot. Maybe you just have a not so great OC'ing CPU.

^It's a QX9650.
What scares me is the Vdrop of 0.05V.
I'm used to such values from cheap boards and cheap PSUs not X48 and PC P&C. But I've never seen a QC at 4.3GHz before so I don't know...
