ok i have been running everest stress test for a hour now, i took off the vdroop control and my temps have dramatically increase and my system seems more stable now, it wont pass prime95, the first 2 cores die on me but my over all temp is staying at 61c at 1.46v, the voltage seems to not be bouncing as much and it actually lowers to an exceptable level, I have bench it 4 times now without a reboot as well, its at 4.3ghz, i think that vdroop control is messing with my computer b/c and this is honest, i dropped the vcore voltage 3 notches and noticed the voltage did not drop then i took the vdroop control to disable and the voltage finally dropped.
 
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. :)
 
i know i saw that and wondered why it posted that, as well as my core is 900mhz and my memory is 1100ghz, that looks weird too, what is scary about the 750w psu
 
^Yes. That's a more like it. But it's still quite high for watercooling.

For scary I figured
2 HD 3870 X2 means ~500W max power draw
and that's a bit scary to have on a 750W and sharing it with a 4.5GHz quadcore the X48 and 2 Raptors.
 
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.
 
VTT or FSB termination is around 1.2V by default I think (not sure for 45nm chips). It plays it's part with every time the logic bus state changes (every value transfered between cpu and northbridge). Not really sure about the details. High VTT is a chip killer (anandtech lost at least one QX9650 to it).

Since VTT is some sort of reference voltage it's impact is likely much beyond that but I don't really know. You should only change it if you really need to IMO.

Vdroop: That's what Vdroop control is meant to do (prevent it drooping below Vcore - Vdrop). But it should stay a bit under Vcore (as it is intended to work) and protect the chip from voltage spikes.
 
Should I take my q6600 out of the box and hook up the water cooling to it. the only thing is that it would be some work and I have the q6600 already built and put in a case?
 
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. :)
 
Andrius, can you give me a link to the paste, i want to check it out, I did pull the heat sink off and noticed some areas where there wasnt paste so i filled them in, I just wait, anyways that is what the game is all about anyways, right?
