The quest for 3.3ghz...

[cadaveca]

I'm not sure. I should be able to get pretty close. The prelim test was to see if the cpu was even capable...I simply dropped temps as low as i could get them, and then cranked up the voltage, making sure that prime95 was stable all the way. THe smaller 120mm rad i am currently using does not provide enough colling for this cpu by itself, so until i get the BIX3, I won't know for sure. It's ordered and on it's way, with the DangerDen full-coverage x1k series blocks.

My memory is currently kind of a limiting factor, as @ 3.35 ghz my ram is @ 238mhz, and showing more bandwidth than @ 256mhz.

although this may sound a bit strange to some, having more with less speed, this is entirely due to the A64 memory controller, which, although this is based on a lower membus speed than my standard clocks, is still not maxed out under current "stock" implementations(AMD settings), and shows just how foolish the move to DDR2 is for singlecore AMD users(IMHO)...and reallly exemplifies the importance of bandwidth for AMD multicores. I'm pushing the limits of my ram, with an extreme overclock...imagine if i had chosen a dualcore instead of singlecore!


I tihnk i may have found a bit of the "coldbug" culprit!

Sweet Work there Dave, i especially like the dremel work for the pump, good luck

sad thing is i have moved to a gigabyte aurora...and i have a opty 170 arriving today.

while playing with this cpu i managed to chip the core in a few places, and smash one of the SMD's on the cpu, as well as scorch another. But now i'm running 1.625 for 3.1ghz on air.


coldbug is bitting me back...have to drop HTT as the cpu gets cooler.

coldbug on water

once i add ice, yes. starts to kick in @ abt 10c, IHS-less. @ 10c i must drop from 310HTT@ boot to 285, but i can just up the multi there, to get the same speed.

Just rigged up today w/IHS. We will see what happens, after i play w/the 170

Just out of curiosity...have you purchased/used an Xpress 3200 board yet?

[cadaveca]

nope. lack of pci slots. If i do, it will either be the DFI or the Sapphire.

got the dfi on order, could have had one by now but didnt want to buy it from the only place it was available

[Seperah]

I see the Sapphire for around $150 on newegg
then the DFI board for $229, and I am honestly considering placing another order around the beginning of June...
