She's up and running. Looks like she hits 37 degrees C full load on both cores @ stock clocks & volts. Everest reports VCore as 1.38V, currently.

anyone know why this is?Quote:

The athlon 64 memory clock is ALWAYS mem speed = cpu speed / memory divider.
what happens is when you select a memory speed in the bios...the cpu picks a memory divider that would be the closest for that cpu multiplier (it assumes 200 fsb).
EG.
2000 mhz cpu = 200 x 10.
for 200 mhz memory it picks a mem divider of 2000/10 = 200 mhz
for 183 mhz memory it picks a mem divider of 2000/11 = 181.8 mhz
for 166 mhz memory it picks a mem divider of 2000/12 = 166 mhz
for 133 mhz memory it picks a mem divider of 2000/15 = 133 mhz
but say change that to a 2200 mhz cpu (200 x 11).
for 200 mhz memory it picks a mem divider of 2200/11 = 200 mhz
for 183 mhz memory it picks a mem divider of 2200/12 = 183 mhz
for 166 mhz memory it picks a mem divider of 2200/14 = 157.1 mhz
for 133 mhz memory it picks a mem divider of 2200/17 = 127.4 mhz
the a64 will never pick a divider that will put the mem clock over the "target" speed.
This is the same reason why "running a divider" doesn't hurt a64 performance much...it's always running a divider...because the memory is still in sync..and still fairly low latency. It's always direct with the cpu.
In your case..the cpu has picked a 14 divider.
lol, im not used to intel mentality, my last intel was the celeron 300a. i just didnt know about the cpu/x thing, i figured fsb x ratio = ram speed. now i undertand, i was always wondering what the cpu/x meant in cpu-z. thank you.
yea..but that's how you calc mem speed on intel platforms =P
it all makes sense now, integrated mem controller and the ram speed is derived from cpu speed, not from the northbridge. and thats why no penalty for using multipliers. thank you for explaining that. AMD is the shiznit.
you're welcome.
but yea...i still chuckle when people refer to running their memory speeds slower than "200 mhz" on an a64 as running their memory on a divider...because it's always on one =P

I think my results seem pretty weak compared to the other 0530s.. =T What other results have people gotten at the same voltage (Using Prime, not SuperPi)
My 165 could do 2.5 GHz @ the same voltage.
2.7GHz Dual prime at that voltage for mine.Quote:

Small FTTs right
Dual Priming at 2.7 @ 1.37V right now.
actually i did it with large, i'm doing it again right now because i forgot to take a screenshot last time. after how much time running prime would you consider it "stable"?
anyone running VX with these chips. im having a terrible time getting it to work well with my vx.
2.7ghz @ 1.312v

large is more stressful than small right?
I've been scouring this thread for a while now and haven't turned up many results from the 180's. What's the average OC on these? Mine shows up monday and I don't quite know what to expect from it yet. Thanks!
your in luck :) i get mine today (YAY) ill be posting results and im running phasechange so youl see some higher avg ocs...Quote:

hmmm, i can get a 165 with the CCBWE 0534SPMW code, do you guys think it's worth it?
or should i just wait until i can get a 170 :stick: (from what i've seen the 170's seem to clock slightly higher :shrug: )
i'm thinking of putting together a second system, but these opterons are pretty hard to get hold of :(
165 9x multiQuote:

Thats the piece of crap i just sent back. From the gate, it ran way to hot.. At stock speed, over 62C with 2 SP2004's going. Stock voltage too. I remounted the block several times and no change.. So, it was sent back. That stepping is horrible.. I got no more than 2.4, the other guy here i think got 2.58 or something. Check back a few pages and you will see.Quote:
