Im thinking of of replacing my AMD Athlon 64 4000 San Diego (socket 939) CPU to an AMD Athlon 64 X2 Dual Core 4400+ (socket 939). Will this effect my gaming performance? I know the 4400 has dual core but its clock rate is 2200 MHz compared to the 2400 MHz of the 4000 san diego. Better for multitasking for sure, but how does it hold up gaming wise?
 
For most games they would be on par. You SD has more cache (1Mb right?) and the 4400 has 512k per core. Some games optimised for dual core (Quake 4, FEAR, HL2 EP 2 etc) would show improvement but chances are they would be more dependent on your GFX card. Depends how much you could shift your SD for, Opteron dual cores can be snapped up for a little over £60! Great OC'ing potential and they have more cache (1Mb per core).

the 4400+ will be 91.66% as fast in single core only games as the 4000+

this is assuming that nothing else is using any cpu time at all.

so basically, they are as close as makes no difference.

and if the 4400+ is a new chip (eg LCB9E and 07xx date) and it wont clock to atleast 2400mhz i would be very very supprised

in dual core aware games, the 4400+ will always be faster

Dbappa: s939 x2's go: 3800+ (2000/512) 4200+ (2200/512) 4400+ (2200/1024) 4600+ (2400/512) 4800+ (2400/1024) FX60 (2600/1024)
AM2 push 512k cores for much longer up the product range, as when 939 was current amd had trouble scaled frequency up high, so rating was raised by adding cache. now that frequency isnt so much trouble, but production space is, higher clocker 512k units are what fills the AM2 lineup untill you reach the top end.

There may well be 2300/512k 4400+ milling about on 939, but it would have been strictly OEM (read HP/compaq) only. none would ahve made it to retail.
 
Hi,

I'm presuming with the mention of 4000+ San Diego we are all talking about s939 cpus here.
For the thread starter, I'm currently running a 4000+ O/C'd to 3Ghz and it goes through everything like a knife through butter. However, I'm a Ghost Recon fan and GRAW2 (due out very very soon) is multi-core aware so I'm in the process of doing what you're thinking about. A x2 4400 is currently in the post, which as standard is the equivalent of 2x 3700+ San Diegos on one chip. I opted for the 4400 to get the 1MB L2 cache per core. I'm also hoping to be able to push it to at least 2.7Ghz...which of course would make it more than an equal for a standard 4000+.
So, it all depends on whether you're going to be comfortable overclocking the cpu or not.

Cheers.
 
As others have said, it depends on whether you overclock, and what games you'll be playing. If, like me, you hardly play anything new then you might be as well sticking with your single core a bit longer. But if you'll be playing anything that's multicore-aware then go for the upgrade.

I'm keeping my current setup until I do a full system upgrade, which is looking like some time next year now as I'm having slight financial difficulties. I could barely afford to replace a dead DVD drive at the moment.
 
thanks for all the help so far. I bought the X2 4400+ and installed it today. I overclocked it slowly to 2.6 Ghz using:-

frequency: 260
multiplyer: 10
vcore: 1.475 v
HTT : x4

this held out ok for a while, played a few games and such with CPU temps reaching 35 idle and 48 loaded. But when i used benchmark 06 it froze during the CPU test. so ive i gone back down to 2200 for the time being. The thing is, im not sure what my memory should be clocked at. Ive got a dual channel PC4000 (2 gig in total) and dual channel PC2700 (128MX64 DDR) (2 gig also) Totalling 4 gig altogether. Could this be causing conflicts? Heres the rest of the system:-

- AMD Athlon 64 X2 4400+ (Socket 939) CPU
- AMD Freezer 64 Pro Approved Cooler
- Asus A8N-SLi Premium (Socket 939) PCI-Express Motherboard
- 2GB (2x1GB) DDR PC4000 Dual Channel Kit
- 2GB (2x1GB) DDR PC2700 Dual Channel Kit
- 250GB Western Digital Caviar SE16 16mb cache SATA-2 Hard Drive
- NVIDIA GeForce 7900 GTX 512MB DDR3 PCI-Express Graphics Card
- NEC ND4570 16x16 DVD±RW Dual Layer ReWriter
- Onboard Sound
- Tagan TG600-U25 600W Dual Engine ATX2.01 SLi Compliant Silent PSU

(Im also looking to get another 7900GTX and use SLI)
 
PC3200 is the fastest Jedec offical DDR1, but you can run PC3500, or PC4000 or PC4400 it will default to 400mhz and you simply overclock it and it will run at its rated speed along with mobo and CPU if they can cope.
 
Hi Baz76,

Got my x2 4400 yesterday (delays with missed delivery etc). I haven't installed yet, was going to do some benchies with my 4000+ first for comparison. It could be your mixed RAM (being 4000 and 2700)...the 2700 will only be rated at 333mhz (that right). With your O/C have you pushed the RAM too ?
I received an E6 stepping x2 4400 toledo rated at 89W with a CCBWE code, what did you get ?

I'm hoping to get mine done over the next few days (work gets in the way !).

Anyway, let us know how you get on.

Cheers.
 
I'm not sure what i should be aiming for as far overclocking my ram. Is the mixed ram such a problem? I don't know what clock speed its operating at, as it was set to auto in BIOS. Could this have resulted in the ram clock speed falling as the CPU speed increased? Ive set it to manual now, but i have no idea where to start.

Ive got the 4400+ stable at 2.4 GHz. I'm not going to push it much further until I'm sure what to do as far my mixed ram is concerned.

Oh. and gunnar the X2 4400+ fared much better than the single 4000+ in the overall performance benches i performed. Also, Games that are dual core aware are noticeably smoother but older games tend to show some of its limitations.
 
Yep mixed ram always creates a problem. Mixed makes of ram can cause problems, mixed speeds pretty much always causes hassle in my experience. Ditch the pc2700 and have 2GB as this will be more than enough atm (unless you're doing video editing etc) but the pc2700 will be slowing your pc3200 down. plus the fact having 4 sticks of ram is never good!
 
I would sell the Pc2700 and put that money towards something else. Then overclock the CPU and you should get better results.
 
OK, Ive removed the PC2700 which leaves me with the two sticks of PC4000. My CPU is currently overclocked to 2.4 GHz. Should i be thinking of overclocking my ram as well? The system seems stable at the moment but I'm really hoping to achieve 2.6 GHz in the long run.
 
Hi,

Well I finally switched my 4000+ out for the x2 4400+ yesterday. took the opportunity to give everything a good clean and dust removal. I've followed the XtremeSystems linky I found for installing the dual core stuff which again went well. However, when I tried to use AIDA32 and CORE TEMP my PC froze...complete lock-up...had to hit the reset switch.

Anyway, Avoiding those 2 progs, PRIME95 ran without errors for 4 hours on torture test with 2 instances (although I understand the 2nd instance runs slower because it uses virtual memory instead of RAM !).

I had it up and running for 3 hours yesterday evening tinkering and it was ok. So anybody know if AIDA32 or CORE TEMP cause issues with Dual Core ?

Incidentally, I'm probably going to purchase Everest Ultimate to replace them. And then we shall see what this 4400 will O/C to.

Cheers.

Click to expand...

I thought that freq x HTT is never supposed to be above 1000?

My 4000+ @ 3Ghz is fine for now, wouldn't be worth moving to a X2 4400+, as I can move to C2D for about £150 after selling my current cpu+mobo+ram :)
