Worth upgrading from fx55 to X2 4600??

If I can find a cheap x2 4600 for my 939 motherboard, is it worth upgading my fx55 clawhammer and try to match the same overclocking speeds with the x2 of 2.78? and would I notice a huge speed diff with the latest games?

At the moment I can change my cpu multi, but with the x2 you cant right, so how woukd I get 2.78?
 
The 4600+ X2's multi is locked to 12x. So you have to increase FSB to overclock the chip.

Maybe look at the possibility of a 3800+ X2? They're very cheap and recent ones are hitting 2.6Ghz on stock voltage, and around 2.8Ghz with a little more Vcore.

At the moment my overclocking settings are 11x253, So to get that same speed on the x2, It will be 232x12. So would the x2 4600 match my fx55 in overclocking terms? and would I see a nice boost?
 
The FX55 has 1mb L2 cache per core, whilst the 4600+ X2 has 512kb L2 cache per core. So in single threaded apps which utilise that cache, the 4600+ X2 will perform worse than the FX55 at the same clock speed.

The 4600+ X2 should reach 2.78Ghz, but there's no guarantee.

In games, if they are new and multithreaded the X2 will wipe the floor with the FX55. However, if they're single threaded, the highest core clocked CPU will give the best performance (FPS).

With the 4600+ X2 you'll see a nice boost in Windows' general responsiveness, and in multitasking. In single apps you'll only see a huge benefit if they're multithreaded.

Just notced the 4200+ and 4600+ are both the same speed???

Nope. 4200+ is 2.2Ghz and the 4600+ is 2.4Ghz.
 
So do I go for it, or stuck with my trusty old fx55? last night I played bioshock, and it ran fine at max setting at 1024x768, the only game it chugs with is Dirt atm, would a 8800gtx sort this out and play crysis ok??
 
As far as games and graphics cards go, I'm no expert at all. You'll be better off waiting for someone more knowlegeable to come along.

Whether you go for it depends on how long you will keep the system and how it performs at the moment.

If you need the upgrade, then go for it. Otherwise save the cash for a new system ;)

Thanks mate. the prob is Im no good at saving money, But im getting quite abit of money in about a yrs time. Im trying to make my sys last till then, then I can buy a bad ass pc.
 
In that case, go for it.

The 4600+ will last you for a year. As for your graphics card, I don't know.

But with the money in a year's time you'll be able to afford an entire new system, so it wouldn't hurt to spend a little now to make your current one last till then ;)

radeon x19** are good cards and will last u a bit
 
Instead of the 4600+ x2 you should look for the 4800+ x2 it has the same clock speed but the benifet of the 1mg cache per core
The overclock you propose is a small one the cpu should handel that no probs
as far as games are concered if you have the cion availeable the 8800 gts or gtx would help make your games fly
it all depends on what your willing to spend
if money no object and you wish to stay with the 939 socket look out for a FX60 which is dual core also starts at 2.6 mgz with the 2mg cache as well
this cpu is possible to clock past 3 ghz.
it shopuld be possible to source one for around £200 via ebay
using ebay you should be able to regain at least 50% of the cost back by selling you FX55
 
In reply to sir-les-mp:

Whilst the 4800+ X2 is a fantastic chip, they are relatively expensive now and difficult to find. The FX-60 was the only FX series A64 manufactured on the So939 platform, but it is a waste of money IMO.

Remember So939 is dead technology. I feel it would be far more sensible to go for one of the Manchester cores which are a lot cheaper, until a entirely new system can be bought.

As speedy2004 is getting enough money in around a year's time for a completely new system, a Manchester will carry him over that year fine without wasting a lot of money on an expensive CPU.

Just my 2 pence ;)

Yeah Ive had a look at the 4800+ for 939 sockets, and there over £100, I would love a fx60, cos that would keep me going for ages.

Before selling my old 1gb mem, I tried it with me new 2gb, filling all 4 slots up and it knocks the clock speed down, it only boots using 2T and couldnt overclock much at all. Will I still have the same probs using all 4 mem slots up with a newer cpu installed? Cos ppl say newer 939 cpus handles the mem better then the clawhammers?
 
Quoted from me in another thread:

GeForce said:
Almost all of the dual core So939 chips were E6 revisions, but there are a few E4 revision ones floating around.

The E4 revision had a problem with the onboard memory controller which meant that it couldn't run 4 sticks of RAM at DDR400 - it dropped them down do DDR333.

The E6 revision, however, will run all 4 sticks at DDR400 without a problem.

As I said though, the E4 duals are rare as anything, and you're extremely unlikely to get one, even less so if you purchase it new. I just thought I'd let you know in case you're looking at getting a second hand chip

I think all FX55s were E4 revisions, which is why you're getting it dropping RAM speeds etc with 4 sticks.

The newer CPU won't have this problem :)

What about with overclocking? please say it wont overclock, now Ive just sold my memory. I did get £74 for it, I was only expecting £50, but it was "Corsair 2x 512 MB 3200 XL Pro" timings of 2 2-2-5 1cmd
 
Sorry man.. but my E6 4200+ X2 is running 1:1 with 4 Sticks Kingmax Hardcore 512mb @ 280MHz (2.8Ghz) and my Opteron 165 before that ran 1:1 with the same at 278MHz (2.5Ghz), Cas 2.5 3 3 7. Damn good price you got for that memory though, would'nt have paid over 40 meself lol.

So if I got a new cpu for my 939 board, and bought another 2 sticks of 515mb (total 3gb) I will be able to overclock passed 220-230 with my memory, At the moment my mem is overclocked to 253, and yeh I know I wont get that out of it with all slots being used, but I need to get any cpu I have to 2.78
 
If you do intend on buying more mem i would advise buying a 1gig kit that matches your current 2 gig kit
this way you should have more room for overclock if they are all the same brand

I think you can only buy 1gb x2 of corsair 3500LL pro and that cost me £160 a few month ago :eek:
