Operating Frequency Vs. L2 Cache

[harobikes333]

so its still better to get the 3800 X2 than an a opteron 165 or 170. As in money value..? P.S. I'm needing the retail version

Opteron 170 FTW!

FTW! <--what does that mean>_<

Do u have any proof of this, sounds like BS to me.

Some links?

It's all about your budget. The 165 is a better processor than the 3800+, but it's also more expensive. If you feel like spending the extra money, go ahead and get the 165. If not, the 3800+ will do just fine.

ok.... so what does TBH mean...>_< I'm not into all the abbrevations:

I can kick in some more money if I have to if the Opteron 170 is worth it.

 

[TheRyuu]

Get this + this.

(or any other cooler = to that)

EDIT: or the 170, with the 170 you get the 10x multiplyer.

I don't really plan on OCing past stock voltage and when I do OC it'll be in like a few years....

Not overclocking is a fool's venture.

 

[harobikes333]

well I don't want to void warranty

Ummm, huh.

My X2 3800+ does 2.4 easily on stock voltage, and runs cool. I have seen several people around here with oc's in the 2.5-2.7 range, and even some up to 2.9

I know you are trying to make a comparison, but lets be accurate.

I don't think you could get an X2 to 2.9GHz even with a liquid cooler. Whoever told you they had done so was almost certainly lying.

As for 2.5-2.7, well, was it stable? Probably not. Did they use a retail cooler? Again, probably not.

You've gotten your X2 up to 2.4 GHz, and that's great. I'm a bit surprised you didn't have to raise the voltage, though. Are you using a third-party cooler? In some cases an 3800+ can get to 2.5 GHz stable on retail cooling, but that doesn't seem to be the norm. Most reach the wall at 2.3-2.4 GHz, like I said before.

I'd be inclined to say that 2.4 is a pretty average o/c, with 2.5-2.6 starting to push it.

And, yes I have aftermarket cooling (zalman7700cu), as I would expect anyone who is serious about overclocking would do. And although the 3800+ doesnt come with the nifty heatpipe cooler, the one it does have is more than sufficient for small o/c's. Also for the record, mine is stable at 2.4 on stock voltage, but i'm sure I can go higher with a bit more voltage. I just like that particular speed for my memory divider (cheap pc3200 ram).

Really, though I'm not trying to argue which cpu overclocks better, I just think you are shortchanging the 3800.

I'll comment

This is my first build so I'm just probably going to stick with what ever stock cooler that comes with the CPU.

CPUs I've narrowed it down to.


3800 X2

Opteron 165

Opteron 170


Just so you all know, I really appreciate all this help!

 

[MrPickins]

I'd have to say that without overclocking, both the 165 and the 3800 should perform very similarly with the extra cache in the opteron compensating for the 200mhz speed deficit.

IMO both offer great price/performance, and both should overclock similarly on stock voltage, as they are the same chips, just with slight difference in silicon quality, and of course the 3800 has 1/2 the cache disabled. However, the opteron might have a slight edge (again due to the silicon).

I may be wrong, but I think the dual core opterons come with the same cooler that the 4200+and higher x2's have. It's a very nicely designed one with heatpipes, and cools as good as many aftermarket heatsinks.

As far as the 170, the jump in price for the extra speed isnt worth the jump in price IMO.

Um as you can see there is some disagreement on which CPU to get...

The opteron 165 is pretty much only OEM right now:\ And I was planning on getting retail so that my butt is covered for three years

Its really hard to find both 170 and 165 retail right now. I think Monarch dosn't have either. Get the OEM with a nice OEM warrenty if you want one so bad.

 

[bjc112]

Here's another difference: When overclocking, the 3800+ maxes out at about 2.3-2.4 GHz. The 165 goes all the way up to 2.4-2.5 GHz on stock cooling. So, not only are the Opteron's L2 caches bigger, but its core clocks are about 100MHz faster when overclocked. And that's why a lot of people fork over the extra ~$85.

My 3800+ can do 2.5ghz on stock cooling..

 

[harobikes333]

anandtech's catch your price on the Opteron 170

That OEM model looks cheap but don't they only have a one year warranty..?

 

[TheRyuu]

With the 165/170/175 or any of the OEMs you can choose a 3 year warrenty for $15.
Just thought I'd let you know. (in the dropdown menu, default is like 90 days or something.)

It comes down to this.
You OC, you get Opty
You don't OC, you get X2

...you get it?

 

[harobikes333]

lol ya I'm sticking with the 3800 X2 uuuuff I can't make my mind ever>_<

Ok I've made up my mind on the CPU and the graphics card and mabe the case but I'll show you all the case later

Now onto the motherboard....

DFI nForce4 Ultra (939) LanParty UT Ultra-D = Price went up:

EPoX EP-9NPA+Ultra = Looks ok...

Anyone have a suggestion/help for a motherboard?

hehe, but mobos to get (if you don't plan SLI):

MSI
or
Epox

Either will suit your need nicly for not a lot of $$$.

(Bump before I go to sleep too, I hope I picked the right stuff, i'm falling a sleep here *yawn*)

EDIT: Forgot the other o in too.
