I can't see how anyone could use the stock cooler that came in the retail box to oc very much. It is sure a cheap thing. Even after a few days at 1.4v under load it runs 42c with pretty good air.
I see your board will run 400, have you dropped the x and tried that route?
PRTeamJapan was specifically talking about this Opteron.....so does anyone have actual figures of performance impact? I know that CPC to 2T loses roughly 2-3% in performanceQuote:

Oh noes his ram didn't break a record when his intent was solely to test an Opteron processor for compatability with BH-5.... can we get back to overclocking?
I just got my opty 146 from vandi this morning...omg the ride there was CRAZY traffic but WELL worth it I only have pics of the chip right now and it's going in the machine soon! will have some results later tonight. anyways here is the teaser for you guys
It's not going into the shuttle:nono: i dont think it can handle 300+HTT so its going in a spare neo4 plat/nonsli using my gskill LE :cool:
oh yea it's the magic stepping of CABNE 0530 APMW

TeamJapan already said it works fine. They DID say that a higher preamble is needed. Thats what needs testing.Quote:

be sure to keep us update asianguy80 on ur results :D
AFI take it easy man......I'm sure these issues will be ironed out.......DFI will need to optimise the bios a bit too I'm sure
I'm not trying to be a jerk but team japan said that you need to run a higher preamble to reach max stable clocks on bh5 with an opteron. Is it to much to ask for someone with an opteron and BH5 to to test it out?
^^^^^^^I'd like to know what he's asking ^^^^^^^^Quote:

TEAM JAPAN TESTED AN OPTERON WITH BH5. THEY SAID THAT BH5 REQUIRES A HIGHER PREAMBLE TIME TO REACH MAX STABLE CLOCK SPEEDS THAN IT DOES ON A DESKTOP A64. It would be nice if someone could prove/disprove this statement by testing it. If you have BH5 and an opteron I'm sure you've maxed the BH5s clocks using a desktop A64 chip. It would take all of 5 minutes to boot your max clocks with the tightest preamble you had before and see if it works.
Thank you ozzi, thats all I wanted to know :)
with BH5?Quote:

you may be interested in that, but i got 4400LCs and the rumor is that certain brainpowers don't work right withum, but i'm just going to take it easy until these things are widely available
yes. i'll try again just to verify :toast:Quote:

either way, i'll be back in a bit with a second word to make sure i didn't do something stupid the first time
NF3=single channel NF4-dual channel ;)

almost correct. i did not forsee switching to s939, thus one of my two bh-5 sticks is still at home in my parents computer. both results are single channelQuote:

sorry about that, i lied. won't boot with 7.0ns.. though it seems that 6 isn't exactly reliable :stick:Code:Preamble Test 1 Test2
4.0ns = 48 errors 76 errors
4.5ns = 55 errors 71 errors
5.0ns = 54 errors 69 errors
5.5ns = 33 errors 35 errors
6.0ns = 54 errors 81 errors - tried a third time, memtest crashed
6.5ns = 44 errors 77 errors
7.0ns = no boot no boot
either way though, seems like 5.5ns is the best in this case
Lower works better? Ok I'm really confused now.
BTW use orange slots for BH5 :)
trying. this board is somewhat new to me :p:Quote:

there's a nice chart. 133mhz = 7.0ns, 166mhz = 6.0ns, 200mhz = 5.0ns. seems to be 1000ns / mhz = read preamble, thus as you scale up the mhz a lower value SHOULD be optimal, but for some reason, other people find the opposite
edit2: the orange slot will have to wait, i've gotta test out the 8x cpu multi first ;)
interesting... I hope I can test this tomorrow :)
