Nice results there, congrats EXPANDER!!!!!

[Ace-a-Rue]

WOO-HOO, look at that vcore...STILL...very nice results!

[EXPANDER]

thanks you.

[Dede99]

is there somebody who tested our board for highest FSB stability that would be also nice to see like over 560FSB+++

i could only get to 555fsb i had done 580fsb on gigabut-x38

[zanzabar]

if some1 sends me a phase kit or some good liquid, or a pot ill test it i have the ram and cpu for it

i doubt it can go much higher than 560 withought a good bios
n i got a great board here
i pumped more volts than i ever pumped into my cpu n couldnt go more than 555fsb n my pwm n nb temps never went above 45c

I got a 60mm x 25 mm fan today to use to cool my PWM area on motherboard. I have temporarily mounted it with velcro tape, but need a more permanent and substantial mount. I am wondering if anyone has any ideas/proven techniques?

While the mount right now is temporary, the results I am obtaining mean it should be a permanent addition. At 3600 MHz and 1.2750 vCore, my System (PWM) temps were hitting up to 67 C with no fan. Mounting the fan to draw hot air away from heatsink brought temps down to 58 C. But mounting the fan to blow down onto the PWM heatsink has dropped my temps by 27 C (from 67 C to 40 C).

For those who have been wondering if adding a fan is worth the time, my results certainly say yes. Now if I can just figure out how to mount it more securely...

I am trying it with snap ties going through spare holes in D-Tek chrome mount. So far it seems to work ok, but if there is a better idea, I would love to hear it.

[sparks]

hope someone can give me some info about temp readings.

E8400 and a TRUE cooler

at 400 buss and 3600mhz
running orthos beta room temp is 68F/20C


I am trying Praz setup and Clunks too

dfi monitor shows

Idle----throttling here back to 2200 on boot
CPU 12C
SYS 31C
Chip 30C

after 30 minutes load with orthos I show at 3600
CPU 31C
sys 34C
chip 32C

OCCT shows the same on CPU temps

I tried coretemp 95.4 beta and 97.1 neither work...they just show 45C

the only voltages I have modified over stock are memory and NB

Memory 2.0
SB 1.51
NB 1.291
CPU 1.1

I just don't feel these temps are correct..what do I need to use to measure correct temps.
IF they are correct I am going to try 450 and see what it goes to.

thanks for any and all help

[Lestat]

1. the first thing to do is look at your other temps.

2. let your system shut down and cool off so that everything is the same temp.

3. turn on your machine, IMMEDIATELY hit the bios and the pc health page.
now look at your NB temps. chances are they will be roughly the same temp as your room. (only at first boot though after that the nb will get warmer and warmer depending on the voltages you use for it)

4. Now look at your cpu temp in the bios.

5. take the difference in those two temps and adjust accordingly.
mine was around 10c cooler. so i added roughly 10-12c to my cpu temps.

the same is true for windows, just look at your nb temps and add a few degrees.
you will ALWAYS know that your cpu is warmer than your room. always.
on air or water your cpu can never be lower than the temperature of your room, ie; ambient temps.

there ya go....

you guys sitting here freaking out about your temps... it doesnt take a genius to figure out how to calculate your temps to a rough number.

[sparks]

well my bios temps show the same thing.
I get worried when I see cpu temps lower than ambient.

I am in the shop and airtemp right now is 64F/17.7F
cpu 12C this is in the pc health status in bios.
Boot into windows and it shows 13C.
so 12 + 10 =22C idle by your statement.
I will buy that.

But max temp is 24 this morning so +10 = 34C running at 410 FSB ?

with these voltages 410 is max stable in windows, anything else and it wont finish the windows and reboots.

is there any program that will display correct temps? I can't believe that coretemp doesn't even run on this system.

I have spent several hours making custom plate for NB from peace of aluminium, and now I have EK Asus block sitting perfectly and covering 100% heatsink (have to polish it though, to get look like D-Tek plate)



But let me annoy u and ask last time about SB
Will be Enzo block CNB S1L (without fan) enough for SB cooling? Or should I get MCW-30?
I just dont want to use a fan, or huge heatsink like Thermalright 05 becoz of some austethic reasons.
So ENZO CNB or waterblock?

Thx again

If you want a passive heatsink, you might be better off with the larger Enzotech version:

Such a significant temp drop might be just becoz of sensor placement and airflow directions, did u try difference by touch.
Though straightout desicion would be getting pwm waterblock, i ordered mine already, quite expensive - 40eur - but i love dfi board so much

Hm, also ive decided use water on south, may som1 suggest variant?

[Jor3lBR]

MCW30 fits perfectly.

If the MSCW30 fits perfectly I don't no why some are saying that the Enzotech SNBW doesn't fit full surface.

In my understanding the Enzotech's surface is bigger then the Swiftech's, from their website the SNBW: Base: 50(L) x 50(W) x 9(H) )mm

Against MSCW30:
43 x 33 x 4mm

[zsamz_]

anyone go past 555fsb yet if so post your settings
i been tryin n will keep on tryin

[PhilDoc]

Best I've done is a 1m pi at 525, but haven't really pushed the voltage.


Had a freaky thing happen today though. I was playing around running 3d06 with a mild oc. Nothing more than I've run before. The system just died. Tried to reboot multiple time, but nothing but C1 error. I reset cmos, still nothing but C1 error. Tried 1 stick of ram and different slot, C1 error. Different video card, C1 error. Took out the battery, C1 error. Left out the battery for an hour, C1 error. I was like sh[t I borked the board. Decided to try the other stick of ram again and it fired up. I though well I've got a bad memory module, but put the other back in and in ran fine. Strange. It must have been the cmos, but I've never seen this happen before. Just glad she's running again.

Which block did you purchase? I am curious about which ones will fit this board.

it happens to me i just turn off power in da back for 3 seconds n all good

My "touch test" shows a significant drop in temps. I am Prime95 stable for 13+ hrs at 3600 MHz with 1.300 vCore. Furthermore, I ran throug the whole range of Super Pi 1.5 XS mod with not even one "hang". In the past, I would need to run Super Pi several times at various times to get results to work, and I was never stable enough for 32M.

My 1M Super Pi result is 14.526 s, my 8M Super Pi result is 2m 59.232 s, and my 32M result is 14m 09.552s. Note that these were all one shot tries. I am sure if I did each step 5 times I would better my results.

I am also running 4-4-4-9 timings on my memory with a 4:5 divider (500 Mhz memory speed) with 2.15 vDIMM. It seems that what the fan over the PWM heatsink did was give me stability, and the confidence to move ahead to bigger and better overclocks.

As for going with an aftermarket PWM waterblock or heatsink, I am a littleskittish after doing the same with my DFI LanParty UT P35-T2R ended up in an expensive lesson in welding (I shorted across MOSFETS when I tightened block to point where it shorted through tape to cooler). It was an expensive lesson

[rioja]

Which block did you purchase? I am curious about which ones will fit this board.

For SB I'm not sure, it seems it should be one of MCW30, Enzo or one of hundred from EK, but which one?

For PWM I know only one option made by MIPS (not my pic yet)



covers mosfets and 2 long details CPL near, 155g

What does it mean? I can't use thermal compound (MX2), or it was becoz of wrong installation? Which block or hs did u try?

Got my DFI a few days ago, so I'll join the club folks
Didn't get to set it up yet, since I only returned from the mountains yesterday. Will be firing the mobo up with my Q6600 with the new single stage unit I got, hoping to get to the CPU's stable FSB limit (was around 480 on the Abit IX38)
For cooling, I will go with Mips PWM and NB blocks when they arrive next week, until then it's stock + fans (hope that will do).

Which bios to use anyways? Using 4x1GB D9GMH, the quad and single 8800.

Thanks for that. I'm in the US, so I'm not sure where I can get those. I'll have to do some looking. Are those G1/4 fittings?

There are only two BIOS files right now. Most people are finding more acurate NB voltage readings with the latest one.
