Opteron 144, 146 or San Diego?

[vrobec]

I'm searching for thread with differences between these, but no luck.

Please let me know which one is better for overclocking and gaming. The prices are similar for Opty and San Diego.

Regards!

144 =1.8GHZ
146 =2.0GHZ

San Diego what? 3700, 4000, FX? Generally speaking, Opty's are tougher cuz they're server chips. For example, I have a 146 that runs nice and stable at 3.0GHZ on air, and I have an FX-55 that runs 3.02GHZ GHZ stable on air. They both have 1mb of L2, and the Opty takes less vts to get the 3 gig mark. You could say that I spent too much on the FX-55 (and you'd be right), but I got a deal at $400 + one helluva mp3 collection (you'd still be right) .I can't remember my stepping - but that can have a lot to do with it.

I'd run with the Opty if I could do it all over again.

Opteron 1xx single core's are all San Diego, along with 3700, 4000, FX55/57 (given they are 90nm), so they are the same chips except for the binning. An FX chip will most likely clock the best. Opteron are thought to be binned better given they are server chips, and because of that they clock high. The recent 3700 have been shown to be great clockers, also. A good stepping in any of them would get you to about the same place, with 3G on air having a good chance.

The new 3700 SD's are great . . . Most of them hit 3ghz on air without any problems :) ;)

I'd go for the 3700+ since the new ones clock very well and they have a higher multi as a 144 or 146.

Thanks for all of you. :)

go with the 3700+ Sweet choice with the multiplier

[@_dud]

the major difference is the multiplier. 144=9x, 146=10x and 3700=11x
They should all hit around 3ghz with a good stepping.

I think they should all top out around the same but that is just luck of the draw I suppose. I myself just picked up a 3700+ but that's only because I got such a good deal on it. I suppose your motherboard would be a factor in the decision if it was incapable of high FSB speeds. Then you would want something like the 3700+ for it's higher multiplier. What motherboard will you be using?

I have the DFI Ultra-D (specs in my sign.). I think I will go San Diego 3700+.

FYI...You can still get an OEM 146 from Monarch for $150 shipped using one of those instant coupons......

They're not.
The difference is in the memorycontroller.
My opty requires MAL set to at least 9 with my BH-5 in order to get it stable over 255 FSB, on a San Diego setting MAL to 7 shouldn't be a problem.

As for the CPU's, skip the opty 144 cause of the low multi, the 146 is a better choice but the San Diego 3700+ is would be my first choice atm.

Actually most of them are Venus Cores..

What revision mem controller for the San Diego ? Newegg has the "older" E4 mem controller, (runs on 1.35/1.4 V) and the "newer" E6 mem controller (runs on 1.35V). I have read that the rev. E6 SD is a Toledo with one core deactivated.

Will the "newer" E6 run RAM any better than the E4 ?

I would be looking to use 2x1024 Infineon CE-6 with the E6 on a Lanparty SLI-DR.

Any thoughts or experiences would be much appreciated !

Thanks !

it seems that all opterons are different. i too have a CABNE 0530AMPW, and i can get to 282mhz on MAL 8 with bh-5... :toast: (i suspect MAL 7 is good to ~275mhz)

[SparkyJJO]

not all 3700s will get to 3GHz though, mine didn't. I'm at 2.86, and that is my highest stable OC right now. Maybe with a little more voltage it could get higher, but I'm afraid to go much higher than 1.5. 1.55 did earn me another 55Mhz but o goody.

Really? :confused:
I think MAL is dependant on the memdivider used.
With my TCCD i could use MAL 8 also (1:1) but right now with my BH-5 i use a 166 divider and MAL@ 8 is only good up 'till ~255MHz for higher memclocks i need MAL@ 9.

I have bought the San Diego 3700+. Prime, 3Dmark, SuperPI 32M stable. See my sig.

Thanks again for all.
