Thanx mate. Without watercooling my nb i would need a fire-extinguisher:DQuote:

Thanx buddy:)Quote:

If you try a bit higher than 4500-4550mhz then youmight be amazed with the results;)Quote:

DRAM voltages are set to 2.0v@1146@5-5-5-15@PL7. Default are 1100@1.9v. NB is under water, and DRAM are with Dominator Airflow. I'm usinge 67x NB GTL Ref., other values don't help. I'm wondering, if i coulde set 150ps different between CPU and NB skews, would it help? Because with both set to normal, over 460 is impossible. Maybe skews need to be more relaxed for 480?
A difference of 150ps between the CPU and NB would be to much. I think it would be better with CPU Clock Skew Delay 100ps and NB Clock Skew Delay 50ps or any other combination of delays with a difference of only 50ps.Quote:

speaking of testing i was folding at home , running GPU on one hand and Boinc with SETI on the other overnight.
no issues. so i take this is pretty good testing anyway, for stability i mean. right?
the last few days is like ....graveyard..... here:DQuote:

There isn't much to say anymore. I'm stuck at 8 X 450MHz if I want it full stable and I think that I've got to live with that because I don't think that we will ever see a better BIOS than what we have now. :(Quote:

I agree with you we probably wont see any - much - better bios for our rampage boards :shakes: but my next step will not be a s775 board anyway.Quote:

Lets see...
A-Grey - tks noted.
Greg.m is preparing for upgrades, some kind of liquid HmmHmm. Or was it dark matter.
Apparently he is trying to break somekind of record here. like The most upgrades in a year or so..
+1 vote for that.
We need lots of pictures,,greg..
Got my new E8500 today and looks like getting anything close to 500fsb or higher requires pretty much voltage on MCH.
Great news i hope you enjoy her...:)Quote:

1.45 is the lowest stable voltage on MCH I've tested so far.Quote:

vCPU: 1.275v, vMCH: 1.45v, vDDR: 2.2v, PL=9, all GTLs and Skews on auto.
Think what you could do with nbv between 1.6-1.7... the prob you have is with the temps. Havent you done something about that?Quote:

Maybe a cooler like this for the NB and a fan

and like this for the SB

61* it's a stress temp, mch gets colder kinda slow - haven't made any changes to mch/ich cooling except changing tim to AS5. Idle temp is 46*.Quote:

BTW I had a third party cooler with a 80mm fan @ ~1900rpm on my NB before I went for water on it and it never got over your idle temp with max stress even though I push volts up in the red value.
Keep up the good work on that RF. :up:
Will have to think about getting some noiseless fans on it. Thinking about getting 7.5 or 8 x 533fsb for 24/7 use but only if I could stabilze nb temps under 55 on such fsb.
here is what i was using until i went on waterQuote:

it has three different speeds and some nice blue leds;)
greg.m found out that increasing fsbVTT gives much more than inreasing vMCH, done on CPU: 1.275, VTT: 1.24:

if i have an E8600 and i want it to be a 5ghz with 1.50vcore wich gtl cpu and nb do i need to calibrate it correctly? divisor 1:1 585 x8.5multi or 555x9 multi gtl cpu 63 y nb gtl 67?¿=
With cpu gtl on 63% and nb gtl on 67% I was able to achieve 620fsb: http://valid.canardpc.com/show_oc.php?id=586151.Quote:
