Hello..

 

this is my set : asus a8n sli, a64 fx55, corsair xms pro 4000 1024 kit..

 

i just bought the corsair.. and now i'm still working on understandig the right setup..

 

I can't go over 466 mhz in bios with ram.. with 3-4-4-8 2T

 

Is this correct ?

 

why not 500 mhz ? like they are made too ?

 

because of the mobo ? and cpu ?

 

Running at 466 will give me a lower clock frequncy.. it is now at 233x10..

i've tried many things but the systen post or freeze or don't boot..

 

please Ramguy help..

Sorry it gives me a 233x11 on default at startup

Do you know if your CPU can OC that high? Yes, they are DDR500 and can hit 250 Mhz.

 

Ram Guy will be back on Monday.

 

Well.. it is an atholon fx 55 i think the best on the market now.. :)

 

but it is not the clock i'm looking for at the moment.. i want the ram running at 500.. and then i will check the spped limit of the clock.. i can overclock without any problem till 2920 mhz .. but ddr will become slow..

That's 2.6 Ghz, right? Athlon 64s don't like running the memory out of sync with the FSB. The LDT multiplier will have to be turned down to 4x as well to ensure the HT bus remains under 1100 Mhz. (4x250=1000)

 

Also, it's typical for the highest speed CPUs to not have much OCing leeway.

Ok.. now i'm running at 500.. i made so many tries with parameters.. and at the end.. but now my overclock range it's very narrow.. if i want a stable system, Anyway the memsetup of the mobo doesn't like the 500 mhz parameters.. i have to leave at 400 3-4-4-8, and after pushing fsb 250 will bring automatically ram at 500. with multiplier set to auto gives me a 10x, wich is a lower speedclock then the original speed processor.. i setted it up to 11x and now system boot ok and work at 2750mhz 250x11 ram 500 mhz.

 

i already tested the the modules with memtest and they're ok.

 

i can overclock more but i'll have strongs stability troubles..

 

also i cant have the system working with lower ram speed but more relaxed timings.. i saw on the internet people testing and doing it.. but it's not my case.. :( let's wait for Ramguy.. thx

Thats actually a great O.C. for this system, and can you tell me the make and model of PSU you have since that was brought up?

 

 

Well i have a fantastic Yesico FLL 550

 

Fanless.. before i had a very good Enermax EG701AX 550 W

 

Wich was very good regarding the power output...

 

The YESICO it's a bit less powerfull because of the fanless..

 

and sometimes i have very little loss of Voltage..

 

anyway i tested memories still with the enermax.. not with the new one

Visus,

 

I just bought ATX 2.0 psu for my mb: Thermaltake 680 watts psu. It's running great.

 

- If you sure about your psu, would you try your settings in DFI nF4 SLI series? FYI I have A8N SLI that cannot go as high as DFI nF4 series. I bought A8N cause it still has LPT ports after knowing DFI doesn't.

 

- Happy computing.
