Worth upgrading from fx55 to X2 4600??

GeForce · 24 Aug 2007 at 17:07

The Manchesters will clock pretty high because of the lower amount of L2 cache to hold it back. And the Opterons will clock high because they run cool and tend to not need as much voltage with increased FSB to remain stable as 'normal' X2s.

The Toledos are the only ones which don't overclock particularly well, but even then, some of these have been very good.

If you can't get the memory to run at the speed you want it to, just stick a divider on it

Im mad spending that kind on money on memory arn't i? I have no idea of memory divider setting, and no idea what im looking for in the bios???

You mean X2 Toledos? All of my Opteron DC were Toledos and o'ced well, minor few did'nt and my curent Toledo X2 4200 does 2.8Ghz @ 1.375v and 3Ghz @ 1.485v, only heat and noise needed to cool it hold me back from running 3Ghz 24/7.

My fx55 [email protected] is roughly the same temp as stock speed temp. 28c-32c idel in the winter and 32c-36c idel in the summer.

Sorry yes, the X2s. The dual core So939 Opterons were officially codenamed Denmark. And as you say, they overclock very well.

The 4200+ X2 you talk about isn't a Toledo, it's a Manchester, which is why it overclocks so well

My board should be fine with a x2 4600/x2 4800/fx60??

No dude, its a Toledo with 1/2 of the L2 disabled. I've had many a X2 and most have had the IHS removed and the difference between the cores of a Toledo and a Manchester is noticable, the Toledo is much bigger. Plus in Cpuz its recognised as a Toledo. As for the Opterons, i've had Denmark and Toledo ones, so they're different cores and like i said they did'nt do so bad in o'cin, the last Toledo 165 i had before i sold it did 3Ghz on 1.5v on air which ain't shabby. The only one i kept and was more a test cpu dosen't do so bad at 2.6Ghz 1.4v and 2.8Ghz on 1.485v, though its currently sitting at stock in a 1U chassis at 1.2v 1.8Ghz

GeForce · 24 Aug 2007 at 19:45

Point taken, it was manufactured a Toledo. But it's now technically a Manchester because it has 512kb L2 cache per core. The point being that it is the extra cache that holds a true Toledo back when overclocking. The more cache there is, the more the likelihood of one part failing at increasing clock speeds.

The Toledo/Denmark thing is a weird one, as hardware wise they're exactly the same I believe.

I'm not saying Toledos don't overclock well. I'm just saying that a Toledo is more likely to be a bad overclocker than a Manchester (either a true Manchester or a Toledo with half the cache disabled).

Well its still a Toledo

The manchester core is different, i would actually expect it to overclock better too due to the smaller L2, the X2 Toledo is sort of like the early Allendales that were crippled Conroes. As for the crippled Toledo, i wonder how AMD disabled it, is it totally dead or activated but bypassed..if the latter then it'll still contribute some to the heat output i reckon.

I Dont believe that,, Crysis graphics cant be tha amazing then, if thats the case. But saying that bioshock runs full detal at 1024, but the graphics doesnt bilow my away accept at the start of the demo, graphics are pretty amazing then.

Phil2008 · 24 Aug 2007 at 21:35

So am I better off with a Opteron 185(Dual,2.6GHz,2MB) and whats the diff between the X2 and opty????

Phil2008 · 24 Aug 2007 at 21:42

Is the opty 185 as fast as a fx60??

GeForce · 24 Aug 2007 at 21:45

Same clock speed, but the FX has an unlocked multiplier.

It will be locked at 12x right? who needs unlocked multipiler when my £160 mem will do 250 and over :eek:

So the 185 can do 2.8 easy? at what temps? cos might aswell use my stock heatsink and fan, cos its done a real good job ad keeping my fx55 cool

GeForce · 24 Aug 2007 at 22:08

The FX55 stock HSF probably won't be enough for a dual core chip even at stock speeds & voltage. They run hot!

The 185 should be able to hit 3Ghz with relative ease. Can't guarantee anything of course

Jon

Phil2008 · 25 Aug 2007 at 14:32

I will prob buy a new 1 with a heatsink/fan supplied, shoud I get about £100 for my fx55 clawhammer cpu?

Im guessing for the 185s the cpu multi will be 12? so to overclock it to 2.8 the memory will have to be on 233 or 234mhz

The Opteron 180 has a 12X multipiler to get 2400Ghz so the opteron 185 should have a 13X multi to hit 2.6Ghz.

GeForce · 28 Aug 2007 at 22:26

Yup, the 185 has a 13x multiplier. Meaning an FSB of 215/216mhz is required to hit 2.8Ghz. Not a big increase really, should manage that without breaking a sweat.

£100 for the FX55 is probably a bit much. Stick it in the price checks forum

Ehhh another 185 buyer! Mine should be here on Thursday so will let you know how it goes over my 4200+
