problems with ram memory

[grzybson]

hi, i have problem . i have one 8gb 2666mhz ram memory but my pc show me that i only use 1333mhz of my memory what should i do?

ddr(number) ram stands for double data rate random access memory. Meaning it transfers twice per clock cycle, so that's 1333x2=2666mhz.

 

If anything, I'm seeing that it's using a very loose timings, which is 19-19-19-43. Since it's using hynix, try using a tighter timings like 5-15-15-35 or 16-16-16-36.

yes that's correct, if I look at my Task Manager, it shows the advertised RAM speed, while HWinfo only shows the rate without doubling the number for the double data rate:

btw this is a jedec 2666c19, model number tells rank config and ic, hma81gu6cjr8n 8gbit hynix cjr single rank (8gb single sided cjr stick)

 

should do 3800-4000 with relative ease but depends on your mobo and cpu wether or not you can actually hit those speeds cause im suspecting a crappy oem board which wouldnt allow ram oc nor timing adjustment

 

Spoiler

heres what cpuz shows at 3400 ddr3 for me so yeah perfectly normal, dunno how to get advertised speed to show in windows though since i have to use setfsb to get this thing from 3312 -> 3400 in windows since it will not bios boot 3400

 

1700 is real speed and 3400 is effective or advertised speed cause ddr
