Opteron 146 CAB2E 0540 FPMW

on MSI K8N Neo2 Platinum

looks alot like my 146 CAB2E 0540FPMW @3102mhz at 1.536v 32M

Hi there, short term lurker and my first post - I got a CAB2E 0540 FPMW the other day, and I am extremely dissapointed

I am having to run it at 2475mhz at 1.55 volts currently - anything higher clock wise and it fails all of my stress tests, within 6 seconds. Even with 1.6volts and slightly higher - 2700mhz on 1.65v is a no go. Super pi fails doing the 128k calculation never mind the 1m calculation.

Using an NF3 Ultra (Epox 9NDA3J) even back flashed to what is considered the best o/c BIOS of the April 2005 version.

I have an AKASA 460W Paxpower CPU,
XP-120 with L1A Panaflo fan
x800 xt pe

I think the CPU is just a really poor clocker, I have tried with the timings and ram dividers on the lowest they can go - but no luck. So far I have run about 10 hours of SP2004 and I think the clock speed I am at is stable now. Also the HTT is set at 3X (275HTT)

Temps under load are 47-49C

Nights Dawn is the 144 or 146 ?

Ahh yeah, it is the 144 version. Sorry forgot that, probably most important piece of info

**Kameleon** · 11-11-2005, 04:41 PM

Shame - this is the best my 144 CAB2E 0540 FPMW can do (prime/32M stable) so far, I've just started burning it in properly and it's responding very nicely

Yeah was expecting a minimum of 2600mhz, and was hoping for 2800mhz ideally, not to worry - I'll have to save up now for a new motherboard and power supply

**ArcTan** · 11-11-2005, 05:16 PM

looks like the 146 does better than the 144 for the CAB2E 0540 chips

Exactly what I was thinking. Good thing we got/are getting 146s

I was reading through the Opteron thread @ OCUK forums and their CAB2E 144s weren't doing very well either.

**G4h4o8s6T** · 11-11-2005, 09:39 PM

Just got my 146, ordered it yesterday from newegg (3day shipping) and it came today

......Its a CABYE 0540FPMW

Im gonna see what it can do with my Gigabyte board, valueram and stock cooler..........2x1gb OCZ EL Plat. and XP90c w/Panaflow are on the way, possibly DFI Ultra-d if my current board doesnt cut it

I work all day tomorrow, so Im gonna have to wait till sunday to pop it in.......Ill let you know how it goes

**manomanx2** · 11-11-2005, 10:26 PM

A lot of your guys' posts don't mention what kind of cooling you have. It's pretty confusing to figure out by looking at past posts.

Also, what speeds are you guys getting using just stock cooling?

**GUFY** · 11-11-2005, 11:40 PM

Do you know what si the optimal bios for Opteron and Geil one BH-5.

I am running 414-2 bios on my dfi. This is good with UTT (I have a pair of Mushkin Redline atm).

I run 623-2 with my GeIL ONE BH ES and also 704-2BTA ... but I prefer the higher VID % which are available in the 623 series.

**eva2000** · 11-12-2005, 06:56 AM

Just nasty

3dmark2003 = 20,223

**SPivX** · 11-12-2005, 07:13 AM

i have ordered myself two 146 CABYE 0540 FPMW with batch 0001 and 0230. Do you think these will be killer OC'ers?

Where are you order this cpu? Because there is CABYE 0540 APMW at trend4pc.de, but no fpmw

Do you know if this stepp is good? CABYE 0540 APMW

**SPivX** · 11-12-2005, 07:57 AM

i ordered the last 2 from informatique.nl. they're gone now :-) i think they'll be available again shortly.

dunno about 0540 APMW though.... all CABYE 0540 OC very well. maybe the experts?

**tatts** · 11-12-2005, 08:05 AM

low batch numbers dont mean good clockers.
someone on another forum has 4 146 cabye's and said his 0500 is the best clocker.
ive got 2 cabye 0540fpbw, batch 0169 does 2.85ghz 1.5V & 3ghz 1.6V but the 0564 does 2.9ghz on stock volts & 3ghz 1.45V (all prime stable)
from what ive seen on various forums, the fpbw seems to need less volts than fpmw (both easily hitting 3ghz tho) & ive seen a few fpaw struggling for 3ghz

I hesitate... but I believe that I am going to try ! I give to you my experience !
