Need Lots of Help DFI DK X48-T2RS

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.

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

I can run it at 1150mhz, so I know its not the memory, can get 9500 mbs on everest across the board.

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.

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

Sorry, Scotteq, didnt mean to be rude.

No offense taken

i am at 70c at 1.42v in occt after 20minutes at 4.2ghz, this sucks b/c my tuniq tower did the same thing

Oh, Andrius, no reboots after i plugged the fans into the 5v motherboard and took them out of the 12v rail

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

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 cant be that bad

That looks quite nice. Is the 61C load the maximum?
Vdroop control could be such a usefull feature. Too bad they messed it up.

On a side note : Why are there 4 GPUs listed on that CPU-Z Validation?
Are you doing QuadCrossfire? That 750W psu just looks way more scary right now.

btw, my temps have dropped down to 40c idle, does this sound more reasonable

Yeah, I know, that totally sucks, well I ran everest stress test over night and my computer was still running this morning, at 1.46v 61c at 4.336ghz so I think im going to stay with that, that is a good speed to use for daily use and the fact that it idles at 40-44c and stresses at 61c is an acceptable level to me, I scored around 22750-22900 on 3dmark06 and that vdroop control totally sucks for DFI, I cant believe that when I had it on that the voltage would never drop.


Does CPU VTT voltage play a part in how many volts are going to the cpu. I also noticed when I increased that voltage that it would make the cpu temp on everest go up, do u know what I am talking about everest shows CPU,CPU1,CPU2,CPU3, & CPU4---- when I raise the vvt voltage my CPU temp was 5c higher then my CPU1-4 and when i raised it and lowered my vcore voltage it would register the same voltage as before. The only time I could lower my voltage was when I lowered my vvt and my vcore voltage.

Im here to tell you that vdroop conrol does not work on my motherboard and from what I am experiencing with DFI's motherboard, i like the fact that that i can take into account vdroop as it is what i am accustom to. Your right on the 9650, i read that article and have set my vvt to 1.10v, north bridge to 1.25v, southbridge to 1.51v and vcore to 1.47v. I am happy with a 4.336ghz o/c. I can use it everyday and not worry about it crashing now. I am just worried why my cpu is so hot even with water cooling. I thought that it would cool it down to at least 30c at idle and you always have that 20-25c rise in core temp when at load. I just have no clue why my cpu is so hot. The kicker of it all is that my Tuniq Tower 120 did the samething this thing is doing. Do you think I could possibly have a bad chip that heats up way to high?

I don't think it's a bad chip. In fact it does awesome. Your H20 kit costs about $150 and it's the best kit by many accounts. If you need higher performance you have to do it DIY with probably a higher flow pump and a better waterblock design (d-tek Fuzion). A larger 120.3 radiator would also improve the heat dissipation and increase the turnaround time (thus giving the fluid more time to dissipate heat). The same could be achieved by a large fluidtank like with metal fins for dissipation (like that Zalman all in one thing).

I doubt the Q6600 will do much better (like you read in the reviews). 4GHz appears to be the thermal limit of this kit. You got 330MHz over that by using a 45nm chip. Leave the thermal compound a bit of time and see if it improves (arctic silver takes some 200 hours to set) and some pastes also take a few hours to a few days to cure properly. Zalman's paste is the exception.
