[First Look] DFI 680i LT NF-680i LT SLI (56K Warning~~~)

Can you post a pic of Smart Guardian to see what NB temps you're getting with the mips gear?

Cheers

I'd like to see those temps too. Load + Idle

Is that two loops or mixing 3/8 & 1/4 inch tubing?

@simon, on dual cores for 400fsb (1600), I find only 1.48-1.51 vnb is usually required, the lock ups will then go away, ldt should be fine too @ 5x...

I will take a screen shot of Smarg Guardian later, but my finding on the temps are as follows: On air at same speeds I was getting both System and Chipset temps in Smart Guardian at about 50c Idle and 60 under load. Those have now droped by about 10c - idle at about 40c and full load i have not seen more than 52c, even with my over inflated NB volts as Raja points out.

My loop.. well the Koolance comes with 3/8" I have taken the 3/8" directly to the CPU then as the 3/8 leaves the CPU i have setup a parallel split using 8mm internal (10mm OT) tube. At the moment one parallel run does nothing and acts as a quick route so i can maximise CPU cooling, the other loop goes to the SB then onto NB then finally Mofset.

Raja - If i set anything less than 1.65v on the NB in the Bios then Orthos (prime) fails with a graphical screen distortion and lock up after time. The time it takes to lock is related to the NB volts i select. i.e. 1.51 gives it about 10 seconds, 1.57 gets to about 30 seconds. I do note that Smart Guardian reports quite low NB volts at 1.65 ut shows the NB as 1.48 / 1.5, so maybe thats why i need more voltage there?

My idea with the unused parallel link is that i can use as a test. Firstly when open i am stopping any major flow restriction because the 3/8 technically goes to 2x8mm or 16mm inner. If i find i needs more flow to the chipset, i can restrict, or cut the flow down that pipe. Lastly its there so i can isolate one of the chipset blocks if needed and run that pipe directly if more cooling is needed... i.e. put the NB block on its own parallel run.

So far tbh, ristricting flow seem to mak no difference at all to any of the temps.

Remember my main aim is to run as quiet as possible at 9x400. So far I can run with the temps described with the fans on the Koolance set at possition 3 out of 10 and thats running prime and in this hot weather. If i wind them up to full speed the temps drop by aprox another 6 - 10c all round.

i agree with raja ... 1.65v is extreme at 400 FSB ... i'd check your other settings first before cranking it that high... i haven't seen one person need it that high for 400 FSB...

i recall a post from tony a while back where he didn't even need that much NB voltage for 450 FSB...

[Raja@ASUS]

a lot of the high vnb requirement probably has to do with you running ddr 1100 I guess..

I initially needed 1.75v on the NB for my quad OC to 400FSB ... keep in mind that there's a 0.12V undervolt on the NB setting... it's about 1.53 actual reading with a setting of 1.65 which is not that high... this is now what I'm running on the 521 bios.

Keep in mind I'm running 4GB of RAM at 1T as well. I think it really depends on your particular proc, NB and RAM as to what voltage you will need. You need what you need... no matter how rediculous it sounds to others!
