Newer steppings on the Opteron 165 170 3800+ X2

[GeezerMan]

I was suggesting the Opty 165 as a upgrade for a 939 socket single core to someone, and I was asked about them being a rebadged X2. I have read some things about the LCB9E steppings being a rebadged X2, some say they are all the same anyway, some say no, a true Opty should have the better memory controller over an X2, and that the LCB9E is actually a plain X2 Toledo core.
Newegg seems to be shipping the LCB9E for the Opteron 165, 170, and the 3800+ X2

Anyone knowledgeable enough to comment on this?

P.S. With the so cheap DDR2 ram, and even more CPU price cuts on the horizon, I'm probably going to suggest he sell what he has and go DDR2 anyway. Though I still would like to know what is the truth about the rebadge question.

 

[AmpedSilence]

considering Opty prices, a total sell off wouldn't be advisable. especially if he isn't a big multi-tasker or gamer. I would reccomend just upgrading the computer to daul-core, but i don't know the full story so take that for what it is.

I have an LCB9E and it runs better than a Toledo. I doubt the validity of that tale. If someone were purchasing Opterons for server duty and got Toledos, could not a lawsuit be in order?

 

[GeezerMan]

My CCBBE Opteron 165 is identified as a Toledo core in CPU-Z, as I understand all Opteron 165 are Toledo cores

I don't think the LCB9E are just rebadged X2's. Hell, even if it is, I'm happy with mine running at 2.8Ghz @ 1.35v (311x9). Based on what I've seen so far, the memory controller seems in line with other Opterons. I have no issues running value RAM at 218Mhz with fast timings and 1T.

Yeah, that's one reason I was suggesting it, people are getting good overclocks out of the LCB9E. How are you measuring the memory controller performance?

Weasel, how is it that you and I always think so much alike?

x2 has 512kb (x2) cache opterons have 1mb (x2)

some of the X2 have a 1mb L2 also

That's a mighty impressive overclock BTW...especially the RAM. Is that at 1T?

Yeah, that's at 1T. It's really not all that impressive, though, since I'm using this RAM. Unfortunately, I haven't figured out how to get it to run 1:1, with my board. So far, it's topping out just past 260 Mhz, and I'm happy enough with that.

edit: Note, though, that it requires .025v more vcore to be stable at that speed, which isn't too bad at all, for an LCB9E.

No, because what you are supposedly paying for on a server-class chip like that is a higher level of testing and validation to better make sure there isn't some hidden flaw in the chip that makes it crap out after a few months or throw math errors every once in a while. The actual design of the chip is somewhat irrelevant.

I'm pretty sure they use at least some of the low-end opty steppings and rebadge them as X2's. I had a 939 X2 3800 that was CCBWE, and in my research I'd found that it's a low-end opty stepping. That's probably the case here. So it's not that people who buy opty's with that stepping are getting 'ripped off' necessarily, I mean the chips were designed to be Opterons, but they're probably a bit lackluster and thus some of them are sold as X2's (mine oc'ed to ~2.5GHz with like 1.45V IIRC).

that is incorrect. my opteron 180 was correctly identified in cup-z. at least, it was until my mobo and psu died a horrible death from my feeble attempts to oc.

well, I said Operon 165 are ID as Toledo, yours is a 180

I just installed my 939 opty 170 from newegg - $115 - and am running nice and stable at 10x275, corsair value ram at 206 (my epox board won't allow 4 sticks to do 1T). BTW - it's an LCBQE chip.

I ran super pi 1.5 and got 26.578 for the initial value @ 32M - sound about right? Runs cooler and quieter with the new cooler & chip compared to my 3000+ it replaced.

Cheers

I am considering this same chip, do you like it? I will only be able to achieve 10x240 though.

you know, it might say toledo core and opteron 180 both. I can't check due to my *cough* power supply issues. I'll let you know.

 

[bryanW1995]

what's the difference between the ccbbe and LCBQE?

Then you shouldn't buy an Intel Socket 478 chip, then. When overclocking Athlon 64's, it doesn't work that way. Even if you only have PC2100 RAM, you'd be able to clock an Opteron 170 to a minimum of 2.75 Ghz, assuming the chip itself will overclock that far. If you have PC2700, then you'd be able to go past 3 Ghz, before you started overclocking the RAM. BTW, I'm amazed, but I had no problem at all reading your sig!!

That's what mine says.

They're two different steppings, and will likely overclock differently.

I have a Jetway A210GDMS pro, not the best of overclockers, the lan craps out around 250 and IDE channels around 240.

Btw, it took them 3 years to do that study, lol.

Eww, Jetway is about as bad as ECS, when it comes to overclocking. You should consider this Opteron 175, which has an 11x multiplier, or even this 180, which has a 12x multi. I mean, 11x236= 2.6 Ghz, and 12x240= 2.8 Ghz. It would be much, much easier than changing motherboards. Of course, don't buy any dual-core chip, until you find out whether your particular motherboard has a BIOS that will support it.

 

[doggyfromplanetwoof]

It supports X2 939 chips, thus I figure it will work with an opty? Maybe? Hehe.

No, not maybe. Any board that will support any X2 will support a dual-core Opty. They're exactly the same processor, one of them is just made a bit better.
