x2 dual 4400+ cpu overclocking.

[Dazboots]

just recieved my dual x2 4400+ cpu.

2 mb cache and on air.

so far managing to hit 2770 ghz on air @ 1.47 volts.

running super pi 32 meg and everthing is ok.

cpu @ 39c under load. chipset @ 40c.

will try upping the cpu core @ will try for 2.8 ghz.

does this seem ok to u guys . dont really know much about clocking a dual.

thx in advance. cant wait to watercool this baby.

running super pi 32 meg and still windows is fast as hell.

my fx57 phazed wouldnt be able to do this. so im well happy.

That 4400 seems a goodun so far under air, did you say you were running the chip naked? Should be even better under water or phase

The overclocking is similar to single core only using Prime95 or SuperPi 32 you need to run two instances to stress both cores otherwise the load is split. You can use the Windows task manager to set affinity (i.e. which core to use) or if running dual prime95 you can set this in prime

Air and water performance will probably max out around 1.5v - 1.53v and phase at about 1.6v - 1.63v. The temperatures tend to go mad after this and affects stable OC

If you can 2.8Ghz dual superpi32 that will be very impressive under air. Normally one of the cores is weaker than the other and this craps out first when maxing both cores

Good luck with it mate ...

But then thats still ok - as long as you force games to stay on the good core and leave other stuff on the weaker one (but still operates fine normally, just not superpi32/prime95).

thx guys for the info im running super pi 32 meg now @ 2810 ghz stable.

on air. vcore is 1.568 showing in cpu-z but temps under load r only 44c.

is this ok. do u think more vcore is bad on air.

will try the other settings u game me

thx m8 will try to get the good core as high as poss.

looks like im running like a fx57 now. but with twice the cache and

1 more cpu just for windows power.

Yup true enough, just wanted to raise the fact that with dual cores Daz could run dual SuperPi 32 to stress each core if he wanted to. Doing this I suppose would help find which core is the best if you did want to set the affinity for ur favourite games or whatever. As far as stability goes I think if a PC is stable enough to run all apps and games you want then that is good enough, stressing programs are only good indicators to help you find that 24/7-stable or bench-stable OC a little faster

I think when the temps start going crazy you will know when you have given it enough volts especially with the dual stress tests if you run them. Load temps on water for me with prime95 jumped from about 45degC on a single instance of Prime95 on nearly 60degC with both cores maxed out

I think you are probably on the vCore limit already for air already but your load temps look great ...

nice 1 m8 thx for all the great info. taken it all on board.

Dual Prime95 setup

If you want to run dual Prime95 this is one of the ways to do it ...

1. Run the prime95 setup program

2. Create two shortcuts to Prime95 called "Prime95 Core 0" and "Prime95 Core 1" for example

3. On the first Prime95 shortcut, select properties and change the Target to "Wherever you installed it\prime95.exe" -A0

4. On the second Prime95 shortcut, select properties and change the Target to "Wherever you installed it\prime95.exe" -A1

5. Click on both Prime95 shortcuts, you should see two instances of Prime95 in separate windows

6. In the first Prime95 window go to Advanced -> Affinity and untick the box Let program run on any CPU, set the Specific CPU to run on to 0

7. In the second Prime95 window go to Advanced -> Affinity and untick the box Let program run on any CPU, set the Specific CPU to run on to 1

8. In the first Prime95 window go to Options -> Torture Test, change the setting to Small FFTs and press OK to start

9. In the second Prime95 window go to Options -> Torture Test, change the setting to In-Place Large FFTs and press OK to start

10. Right click your taskbar and open the Task Manager which should show CPU at 100%

I haven't got my machine up and running at the mo so hopefully I haven't missed out anything, good luck m8

just run custom pc benchmarks and cpu on air.

did very good for a first run. running 2.8 ghz.

and my overall score was 1.66.

putting me 5th on the leaderboard.

im first in the rankings to go totaly on air.

@ least i did good with this new cpu.

well chuffed.

my old score with a fx57 @

3.5 ghz phazed cooled only hit 1.50. now on air with a 330 quid cpu.

hitting 1.66.

Nice work Daz - Keep going!!

TEAM EPUK 4EVA!!

lol i wanna dual core now - got other project on teh go at teh mo though lol.

basically, if you don't need all the abilities for each opteron cpu to have its own dedicated memory and all the other little opteron specific things then X2 really is the poor man's route to opteron-like power. Plus they don't have shared cache so there should be no problems and you don't need registered dimms.

X2 pwns.

Phil - go on, get a 3800+ and swap it out

BTW - which of the X2s OC better?

TBH, I think I would go for the 4400+ as it has the extra cache and I would lower the multi anyway on the 4800+ - or as the 4800+ has a higher rating it might be able to go even further? hrrump. But then again surely lower cache version like the 3800+ should skyrocket even further?

Fantastic first score m8, with better cooling this chip could break into the top three Go Daz go!!
