Awesome temps on my Opteron 146 CABYE 0540 FPBW cooled by only Corsair Hydrocool with 1/4" tubing in 30+ C room temps http://i4memory.com/showthread.php?t=1594

Changed to 510-2FIX bios with 2x256MB Gskill PC4400LE TCCD 431 in Yellow dimm slots and much more stable it seems

Room ambient = 29.5-31.5C right now

CPU idle = 37-38C
CPU load = 48-50C

Once again, nice work eva.

One thing I was curious about; how do you know which motherboard BIOS to use? I suppose you could flash to every single BIOS, and test results. But that would be extremely time consuming.
Yeah, I'm not very good when it comes to hardware-specific BIOS.

Awesome eva2000, glad you got a good one.

i bet that thing is stinkin fast!

The Coolest · Oct 28, 2005

CABYE is a new stepping I think, the 0540 also means its a pretty new CPU. Great clocks!

um...when i click your pics...they stay in their small thumbnail size.......

Midnight Dream · Oct 29, 2005

Very impressive. I cant wait to get mine in and test it out

yeah that's due to the forum's javascript to auto resize images... if you follow original thread in first post to i4memory results you can see the larger images

thanks guys which bios to use really is what ever is on the board at time prior to installing the new cpu unless there's issues that i change bioses based on what memory i want to test the cpu/board with

Changed ram to 2x 512MB Patriot PC3200XBL TCCD

Talk about low temps, this cpu is alot different from other Opteron 146s more vcore >1.6v usually seens pretty high 50s/60Cs temps but look at this

@3031mhz at 1.648v

Load

Room ambient = 26 - 27C

EvilCloudStrife · Oct 29, 2005

i want one now...

ps2cho · Oct 29, 2005

that looks like a solid chip. Looks like AMD have some great chips now. Imagine that thing in a server motherboard, two of them with SLI 7800GTX's

eva2000 · Oct 29, 2005

Yeah pretty good still not as good as FX-57 mem controller wise but nice

@3050mhz at 1.648v - here seem to hit memory limitation for 2x512MB Patriot PC3200XBL TCCD ram @305mhz 2.5-4-3-6 at 2.69v

Tell Me How Fast U Feel In Windows!!!

That's A Crazy Clock!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

eva2000 · Oct 30, 2005

well kind of normal for me as i usually run FX-57 @3ghz at 1.4v hehe

but here's my 2nd Opteron 146 CABYE 0540 FPBW
cooled by Corsair Hydrocool 200 on DFI NF4 Ultra-D R.AD0

System

2x512MB Patriot PC3200XBL TCCD memory

Memtest86+ 1.55 from 510-2FIX bios

vcore - results

AUTO (1.38v) = 2900mhz 10x290mhz - standard 2 full loop passes error free

1.45v = 2950mhz 10x295mhz - 7 standard full loop passes error free

1.475v = 3000mhz 10x300mhz - 2 standard full loop passes error free then looped test #8 over night for 371 passes over 11hrs 08m 23s

Seems on Corsair Hydrocool, the 2nd Opteron 146 temperature wise is nearly same as 1st Opteron in terms of low temps. This 2nd cpu seems to be able to handle 0.025v - 0.050v less vcore for 3000mhz speeds.

Room ambient = 28.4C

I went on the assumption that this 2nd Opteron 146 is about same performance wise as 1st cpu so jumped straight into OCCT and looking good

Seems this cpu has maxtcase = 61C which is 2C higher than first 146 (59C).

Sheesh, you work in a CPU factory or what hee hee. :santa:

i wish

step by step going higher OCCT wise

higher we go
