[Athlon x2 4000+ OC,ram bottleneck?]

OK,im finished with the testing...and my theory is right!!! overclocking my ram gives me more performance than cpu!! wow

RAM

553(341cpuz) winrar 900kb/s 30fps in dirt2

667(390cpuz) winrar 970kb/s 38fps in dirt2

800(455cpuz) winrar 1060kb/s 40fps in dirt2

its running at 2v now,havent tried lower voltage,but i think 2v is ok.

Bad thing is,the max i can get the ram to is this.For more i have to lower multiplier and increase fsb,but after 260 fsb(my current with max multiplier)I get insane instability,sometimes pc cant even boot and never gets to windows

 

So thats it 910mhz

[Athlon x2 4000+ OC,ram bottleneck?]

ok,now dont say im crazy ,but I have run 3dmark and i have more cpu score with ram at 667 then at 400.Also Winrar shows 750kb/s with 400ram,and 1020kb/s with 667.

Shoot me! All in all,downclocking my ram to 400 from 667 decreases my CPU power by around 30%

 

Just to ask,cuz i will make a little test.What is safe to overclock my ram to? just to test if my theory is right,more ram speed,more power .I am going for 800+,will 900 be safe.Its running at 1,9v default(selected by my mobo)

[Athlon x2 4000+ OC,ram bottleneck?]

My cpu temp is fine,around 45c on Prime95.

My mobo is k9n nforce 570 sli(the red one,not platinum)MS-7250

 

I ran that Throttlewatch and it shows 1-2% cpu usage,2729mhz,1.350v...I dont see anything wrong in those numbers,except that the cpu speed jumps to 4,5ghz from time to time

Also,just to clarify

The only thing I change is ram from 667mhz to 400,and my fps drops by 10.

I dont have Trfc timing in bios.

This is the reason i lowered my ram to 400,it was only temporary while i was ocing the cpu.It is running absolutely stable at 667mhz now.But why my fps lowers so much if i lower it to 400?Its like cpu is not overclocked ..even tho it shows 2725mhz.I am wondering if I overclock my ram to 1ghz,maybe i get even 50 fps ?

What is causing that performance impact.I didnt expect even 1 fps less when clocked to 400..but it lowered it from 40 to 30!

[Athlon x2 4000+ OC,ram bottleneck?]

hey guys,I have successfully OCed my cpu to 2725mhz(260fsb)

My ram is DDR2 800mhz,cpu-z reporting 390mhz(780mhz).I set it to 667 in bios.

FSB:DRAM is currently at CPU:7

With this setup I get Average 40fps in Dirt2,on ultra graphics.

 

Now the problem!

If I lower my ram to 400 in bios,it will run at around 270 in cpu-z.

Still my cpu is at 2725mhz,but I get Average 30fps in Dirt2????

Can somebody explain how is this possible,why my ram bottlenecks so hard.How do i find the point at where i will clear the bottleneck
