Issues with RAM speeds

post #1 of 9
Thread Starter 
Well, I just built a semi-new computer and my RAM (Patriot Sector5 (1600MHz)) won't operate at 1333MHz. Matter of fact it operates at 920MHz as proven by both CPUz and BIOS. No matter what the BIOS always kicks the FSB:DRAM ratio back to 1:2, even if I manually set it to 1:2.33, 1:3.33, or 1:4.
Can I get some feedback?
The timings are 7-7-7-20-27 and stock timings are 9-9-9-24-35.

Need some more information than that. We need to know which motherboard, bios version.

Is the motherboard in question the one in your system specs?

I hope you're not overclocking on that board (in order to get the weird RAM speed/bus speed ratios)
Very bad idea to overclock an x6 125W on a cheap MSI board

Besides this good point....

If CPUz is showing 920MHz, then your RAM is clocked to 920MHz. Which in turn is DDR3-1840. 920 x 2 = 1840. You get the x2 because its DDR (Double Data Rate).

Yes, it is my mobo, yes I know that its a cheap board, yes I know....
Sorry I should of specified, CPUz is showing 460MHz, I already corrected for the DDR.

Well, I got it going. Had to reset to defaults then redo the ratio. I'm not quite sure what happened but it failed to set the freq. right. Now, I am running at 716.7MHz at a 3:10 ratio.

Your bus clock is running around 217Mhz... so you're overclocked a bit. This would indeed result in improper memory speed. Until around 240Mhz, you won't be able to get to a RAM multiplier (or FSB:DRAM ratio if you wish) that'll let you run 1600Mhz. Of course, I still don't recommend any overclocking on the x6 with that motherboard either... too dangerous

Yeah, I haven't completed fixing my settings yet. I decided to go to sleep once I got the memory to "work" like its supposed to. I am going to probably revert to stock FSB because I know that its bad on this particular board. The reason that I changed it in the first place is that my mobo wouldn't read the correct speed for the memory, so in order to try to acheive it I upped the FSB. If you look up the mobo it says it'll handle 1600MHz OC'ed but I really just needed 1333MHz for the CPU, because I believe that the CPU doesn't even utlilize anything over 1333MHz. I'm not too worried about blowing the board or the MOSFETs because I have 2X80mm fans blowing directly on them and if they blow, oh well just build another one.

We'll see if I do an overclock, but it won't be too harsh.
