Hi,


I took all your suggestions and instead of buying an Athlon II x4 640, I got a Phenom II x4 955 black edition. What do you think!!!!!!!!

My system specifications are:

AMD Phenom II x4 955 BE
Asus M4N75TD 750a SLI
Corsair XMS 3 4gb 1600Mhz
Sata 500GB
500W psu (will upgrade it to a Corsair GS 800W PSU)
geforce 9500gt 1gb (will upgrade it to a GTX 460 or a 560)
LG DVD RW


but I have one issue. My 4GB ram is running at 1066mhz when I saw my bios settings. please help me


and the CPU-z screenshots.



this is my ram http://www.newegg.com/Product/Product.aspx?Item=N82E168...

You need to set the speed, timings, and voltages manually in BIOS, your board looks to the RAM to get the SPD settings, since those sticks require 1.65V at 1600MHz, their out of the box stable settings are probably 1066 which is why your board defaulted to that, you should have no problem setting them higher.

How do I set them higher. I dont know how to overclock memory.


but I know how to overclock my processor (since its a black edition :D  :D  )


please tell me the steps as to how do I set the settings for my memory manually under bios.


and does my motherboard support 1600Mhz...

Its got an nVidia chipset so the BIOS is likely quite different, but look for an AI Tweaker tab in BIOS, in there you should be able to find some DRAM voltage and timings options, it will be in there. You may have to enable AI Tweaker or something to get the menu to show you all the options for tweaking settings.

there is an AI tweaker. but my question is what all do i need to edit if I want to increase the speed of my ram.

Check using CPU-Z in the SPD tab and write down the timings and voltage it says for 1600MHz, when you go into the AI tweaker tab it should match up pretty well, make sure you change the voltage too or its not likely to be stable.

thank you. and one more question.


what do you think of my build with phenom II x4 955 BE and the SLI motherboard.


will it run 2 gtX 460's in sli better or would it be a bottleneck

I will overclock it after I get myself a decent PSU and an after market cooler such as the hyper 212 plus. I will also be upgrading my monitor to a 1680*1050 res.


I see an option called NCC (nvidia clock calibration), the same as acc in bios.


what is that thing. I know it can unlock cores on x2 or x3 cpu's but what does that have to do with an x4.


Do i have to enable it even on a phenom II x4 955 be processor. if yes, then what difference will it make.

No. I wont be taking any chances with the stock cooler because at idle my cpu temps read 44 to 49 degrees now.


so I better buy an after market cooler and I will not turn on the NCC. its better to be safe correct.

For what it's worth:

My 955 and Gigabyte 790xt-UD4 seemed to prefer lower frequency, but faster timings. I clocked down to 1333 and lowered to timings to 7-7-7-24 with my Ripjaws and my RAM benchmarked better.
