What do you define as ridiculous volt's? Here's one of the two 144 CAB2E 0540 FPMW's that I got. I don't have any prime screen shot's but it's first night out it ran for 12+ hr's at the speeds below. 1.62 in the bios, showing 1.52 in windows using the latest version of cpuz. If you don't want to take my word for it, I'll see about getting some screens after a night of p95.

Just a Update on my OC so far of my 146 CABYE 0540 FPAW

http://img.photobucket.com/albums/v1...and7/146-3.jpg

Was a little unstable @ 3.1 but did run a 1M SuperPi with NP. Can probably get a little higher with some memory tweaking but I think its starting to run out of gas. :confused:

Doing 3GHz stable 100% load for 24hrs at only 1.45v :D
All of this was with watercooling.

Can anyone answer me this question......

I just got a DFI mobo from Newegg. It was not shrink wrapped nor was there a sticker between the box and cover. Do DFI mobo's not come sealed?

I just want to know whether I was duked with a used mobo, or this is how they come.....

Thanks in advance

I bought my DFI from a guy on ebay, it came in a brown box in an anti-static bag with nothing else. I am 99% sure it is brand new however.

Mine 146 0540 CABYE FPBW can do 3ghz @1.408V...but it is stragne, cause 3times it passed 16h+ SP2004 now can`t pass it any more...but is OCCT, Super_32m and 3dmark05 100% stable...I can`t pass 300HTT stable even at 1,55V...could it be the MOBO that can`t do 300HTT+? This is my 2nd Ultra-D MOBO and before I had an 0517APAW 3000+ Venice that can`t pass 300HTT...but when I sold it to a friend he can run it @320HTT withouth problems... :slapass: :slapass: :slapass: I have changed alos the PSU but the problem is still here...Any ideas?

Regards,
Primoz

If u ask me the reason is freaking Tagan PSU´s that sux and are limiting my OC with unstable lines

Thx Shark for your oppinion...I had an Tagan 480W before this one and I also think the PSU it could be the cause of instability...

I have the same PSU as you Primoz78, Tagen 580 U15 Modular

While I have'nt checked out the rails yet (will do later and report back) it certainly has not changed any of my overclocks or stability after I very recently changed from my Bluestorm 500 which my Son needed (stole :eek: )

Havent you adjusted the pot yet?
My tagan 480-u22 was reading 11.7v on the 12v line when stressed. The trick made my psu much more stable and is now reading ~12.05v at full load.
Works as well for the Tagan 530-U22.

Does anyone know what is the highest overclock on a 146 (or any other Opteron) with stock Vcore? I'm at 2920MHz 40 Minutes Prime Stable on my 146, will throw 32M at it later.

Got my 146 CABYE 0540 FPMW today. So far this is the best it could do with the boxed cooler:

Couldn't even run sp on this speed though, more to come :D

what do u guys think adding some voltage do my opteron 144, i have h2o , temp are like @3 ghz under 40*c
is 1,7v safe or shm :slobber: ?? my opty loves voltage
11-17-2005, 06:42 AM
ManagHead

I think 1,7V will be just fine so long the temps are respectable.

After some more testing I can do sp 1m on 3ghz, but it's too hot! From 1,5V to 1,52V its getting just worse. May I will test under my phase change cooler later..

finally got my 146 CABYE 0540 FPMW

went stright for 2.7 on stock volts all seems stable enough. done on air using Gigabyte G-Power Cooler Pro ( had to recycle the as5 off the heatsink and my old winnie to use on the opty as i left my as5 at my mums lol) so far looking promising
