i dont know tbh, i have always been under the impression that the chipset pretty much treats 1 512mb stick like 2 256mb sticks in the same slot (unless its a dual channel memory configuration :P)

Wow, amazing results. I'm really looking forward to the water results as well.
Only 7 more days... plus shipping :)

It depends how the traces are laid on the memory stick.Quote:

With 16 chips per stick you've got no choice.
The 940pin chipset supports well doesnt suport, but will run 4x512 at 1t command at ddr400. All the 940 ads really is an extra pin for ground termination and an extra few wait states If I remember so I can't see it being all that hard to adapt it to 939.. But then again for some strange reason maybe its impossible, lol.
Maybe its the 940pin's thick arse PCB that can help with this as it uses a 6layer the 939 on a 4 layer. maybe its a combo of design and low noise that can allow the 940 to do it. "confused"
the extra wait states are through the reg memory afaik, right?Quote:

and stevil, are there really ram makers that put 8 chips on a 256mb stick and wire it like its 2 banks? wth are they smoking? :lol:
i wonder what micron thougt as well though when they made this 256mb stick with 4 memory chips on one side i have here :stick:
bad news btw, pc ice hurt his back trying to lift his cascade (dont try that at home kids! :D) and he has probs going on with the testing it seems since his back hurts a lot.
and he said he has the water and air results on a raid array he has problems accessing now but will post the results asap.
lets all wish him to get well again soon :toast:
Ive got a few vicoden he can have if it helps testing? ;) lol
as for 940 yeah the wait states and so on don't seem to hurt performance at all. It was more the HT sped gain from 939 over 940 and that the newer chipset nf3-250 - nf4 where at the time all 939.
I would like to see an nf4 Tyan with a single 2.6ghz 252 opty at 2-2-2-5-1t and twekaed with a64 tweaker and then compared side by side an fx55+dfi nf4 at same settings ;)
ouch that gotta be heavy such a cascade lol :)
OPP wasn't there to spot him? :hehe:
Man that sucks. No one knows back pain more than me. I've just been recovering from recent fusion surgery which was the 6th surgery I've had on mine in the past 2 years. I'm feeling your pain Pc Ice. And I also have some very good narcotics if you need them. :toast: Feel better
lol, no drug trading on xs please :lol:
yeah, i also have probs with my back a lot, get well again soon dave! :toast:
Holy Mackrel I dont think I want a cascade if its that heavy. Oh well Patience is all I have anymore. Take care of that back ICE!
pc ice told me he could bench with 2.8ghz and 1.4v (stock) on watercooling, so sounds like good news to me! :D
cant wait for the results! :D
is that prime stable?
many 3500+ clawhammers are able to do 2.8 on water with a bit more voltage prime stable, some can even do it on air..
I hope your back starts to feel better soon pc ice. Take it easy as your health is more important than some oc'ing although some may beg to differ.
stock volts + water @ 2.8Ghz = :slobber: Once you get better keep up the great work.
i dont think pc ice wasted the few days he could play with this cpu running prime to see how stable an oc was ;)Quote:

and again, it did 2.8ghz stable for all benches with STOCK vcore, so im pretty sure speeds above 2.8ghz can be obtained prime stable with more vcore.
this is great news for me, now all i need is a preorder button
no screenshots???
Very nice
:woot: still on stock voltage
keep going, dave....
Dave... Did you have a chance to see what was the max 3D or SuperPI benchable for 3500+ with max voltage neccesary? Did upping voltage give any gains? Were the 4x512MB sticks all same brand-speed rating TCCD?
odd so it didnt respond to higher volts under water cooling. Bummer, so its either stock volts or nothing.
Now that is what I wanted to hear. :DQuote:
