Put a couple of other threads up but thought I would bring it together and was wondering if anyone can answer a few questions for me to tidy my thoughts up.

Got an NFI Lanparty SLI-D
Opteron 146 on water
2 x 1GB Giel Value dual channel
6800NU (6800GT now dead!)

Cant seem to get past a FSB of 260 without it failing to post. Tried mem dividers to rule that out but can someone tell me:

What BIOS should I be running with?
Max voltage for the Opteron and the RAM?
Max temp idle/load for the Opteron?
best way to rule out the RAM causing the problem (apart from dividers)?



Any other thoughts/settings I've forgotten?

Cheers
 
Cheers, will try it when I get home from work. Have tried on my 3000venice but had the same problem (ish). Put the RAM on biggest divider (1/02) and still couldnt push it beyond 265 FSB.

Am hoping that the Opty can get to 3Ghz on water but to do this I need to push it to 300 x 10. The temps were really low at 265 (28idle/39load) so that shouldnt be a problem it just seems the thing wont post past 265.

I've even upped the vore to 1.55 (*110%) which is 1.7 although the mobo does undervolt by 0.05 so it should be ok.

What else could be stopping the machine posting? One other thing is the N/B seems to get about 15deg hotter with the opty in, any clues why?
 
Will do, finishing work soon and will have a crack at it after feeding the dog!

Cant believe when I rang up DFI (15mins international call) they told me Opteron wasnt supported by DFI!!!!!!!!
 
Well, still got the venice in and up to 295 FSB x9 multiplier = 2656 with the memory at 147mhz.

Will go as far as possible then swap over to the Opteron. Guess it was a memory issue. Not sure why as it memtests to 205 but when clocking the chip it wont (can only use 1/02 divider to work!!)
 
Thanks Louis Y for that will give it a go tomorrow. Venice is now prime stable at 300FSB x 9 = 2700. Temps good at 42 whiles under load.
Not sure what pwmic means but thats at 57 and the chipset is at 44
Vcore at 1.6, LDT at 1.26, DRAM at 2.7 and chipset at 1.57 (all mbm5 readings under load)
RAM at 150mhz CPU/18, 3,4,4,8 2T
Will push as far as poss then change for the opty. Then I will look at the ram to increase the speen and tighten the timings.

The info you gave is perfect - will use and post the results tomorrow
 
chipset not watercooled, just have sides off case, not even a case fan at the moment. Had the board 7 months now but never been able to get it above 265 before!

Put a fan on the pwmic - dropped down to 47 quite quickly. Must go to bed now, will leave prime95 overnight, cheers louis

Jimbo - mem timings are above, 3,4,4,8 2T running at 150mhz on a 1/02 divider - will look at these tomorrow. This venice keeps going - not sure if I need the opty 146 now!!
 
Well I think Ive reached the limit of the Venice:
305 x 9 = 2745
vcore 1.6 40 deg under load pwmic 38 deg
ldt 1.3
DRAM 2.7 3,4,4,8 2T
chipset 1.6 43 deg under load

Have tried upping voltages etc but wont get to 310. Think its time to put the Opteron back in!
 
Opteron is in, pushed it up to 280x10 with 1.6v vcore, 1.4v LDT and 1.6v chipset.

Temps are vcore 31/50 (idel/load)
Chipset 42/43
pwmic 33/40

Think I need to let the AS5 settle in a bit so will prime95 it for the next hour and then push it to 290.

Edit

Up to 290, same volts, now, tightened down the block a little and seemed to help by 1 deg!

Temps are vcore 31/49 (idel/load)
Chipset 43/43
pwmic 35/38

3Ghz!!!!

:D :D :D

Made it to 300, same volts.

Temps are vcore 31/49 (idel/load)
Chipset 42/43
pwmic 34/39

Leaving for a few hours to prime then going to see if I can drop the volts a bit. There was me thinking it was the mobo and all the time it was the RAM (although probably wouldnt have brought the opteron if I'd managed to get the venice that high before! :cool: )

Thanks for all the help guys, really was spot on
 
Need to get a decent graphics card first as I fried my 6800GT.

It seems I'm limited to 305 FSB (same as with venice so think its the mobo). Tried upping LDT, RAM and Chipset volts but no joy. Would like to push further as the chip definitely has more in it (have dropped vcore down to 1.55 now at 305 no probs). Anyone any ideas - suppose it could be the RAM again but already on largest multi so its only running at 157Mhz????

Seems stable - might just stop here and start lowering the volts a bit!
 
Mmm, failed prime95 after 1h45mins @3ghz, 1.55v need to look at this as I think my RAM is the problem again. Think I need to buy some quality RAM. Temps are no problem. I'm also using 2gb RAM so will take a stick out and try that.

Thx for the sp2004, have downloaded and will try
