Please help my ram isn't working like it should. Could xd 1771 look please?

Hi xd 1771, i hope you found this because you were able to help somebody else who had my motherboard too.
I have found your help on this other thread useful regarding my motherboard here is the link : http://www.overclock.net/amd-memory/...ram-speed.html My problem is that I my ram isn't performing as fast as it should be.
I have this ram: http://www.newegg.com/Product/Produc...82E16820233147
and this motherboard : http://www.newegg.com/Product/Produc...82E16813130275
with win 7 64 bit

at auto settings the ram was 1333 and had funny timings.

I went into the cell menu and changed the fsb / dram ratio to 1:4 and the timings to 8-8-8-24 like the ram says it can do. Restarted and ran cpuz and it tells me my ram is dram freq of 800 with the 1:4 ratio and 9-11-11-29. It also says my NB freq is 2000. I honestly don't know what a lot of that means I just want it to perform like it says on new egg at 1600 and 8-8-8-24. I have a am3 quad core processor that is not over clocked. I know that on new egg it says that my mother board can run the ram at 1600 but needs to be oc'd. the ram will however run at 1600 too so I thought it would work.

any help would be great!

When you look at the ram speed in cpu-z keep in mind DDR means double data rate, so if it says 800 its running at 1600 mhz

NB frequency is the speed at which the IMC in the CPU is running, yours should be able to get to around 2600 mhz pretty easy and it will help give your ram more bandwitch

Your timings are bad, set them up like this and set the DRAM voltage to 1.5v

CL: 8
tRCD: 8
tRP: 8
tRAS: 24
tRC: 40
CR: 1t

Hi, and thanks for the advice how do i change the NB freq? and the 1.5 voltage should be ok I don't need to have it any higher? I will try to input your
CL: 8
tRCD: 8
tRP: 8
tRAS: 24
tRC: 40
CR: 1t

settings. last time I only did the 8-8-8-24 part not the other tRC thing. Thanks I'll try and make those changes restart and let you know what stuff says.

Deneb dosn't have that strong of an IMC so if you get higher then 2500-2600 mhz NB then you've got a decent CPU so just try and see what you can do.

Take a look around your bios, you'll find it. Those ram timings should work, as they are the stock ones. If you have any problems with them try a little bit more voltage or looser timings

Thank you I changed the tRC part to 40. Does CR set to 1t from your settings does that stand for command rate and is that aka the memory timing? If so I did change that to 1t, hopefully that is your CR 1 t setting you were talking about. I'm just happy then that cpuz is reporting what it should be doing. I'm also glad i learned that if it says 800 in cpuz that that is the 1600 speed i was looking for and not half that!

So my last question is how can i change the NB frequency and what would you guys recommend and how do i do that.

Lastly with my motherboard http://www.newegg.com/Product/Produc...82E16813130275 and this is my processor http://www.newegg.com/Product/Produc...82E16819103808

What overclocking recommendations can you make for me? I wouldn't mind oc ing it just a bit, not a lot. How would I do this and check to know that it is working. Thanks

Take a look at those guides, they should answer a lot of your questions. If you have more questions, go a head and ask.

Which cpu cooler do you have? That's also a determining factor in your overclocking

I still can't seem to find the NB freq setting is that for the ram or the cpu? also I did find a cpu NB ratio with settings of x8,x9,x10... and x20 but i don't know what those mean or what to pick. It also says that the ratio must be greater or equal to the HT link speed? whats that and how do I check that too?

Thanks for the general links about the oc my cpu I will have to give them a read soon. Thanks again this was worth my time definitely.

I think Yumyums was able to answer most of your questions
NB frequency should ideally be 3 times the speed of the RAM (before dual data rate - so 800 x 3 = 2400Mhz) to avoid bottleneck. CPU-NB voltage pertains to the NB frequency. Raise it if/as needed.
