Ram Frequency ?

post #1 of 10
Thread Starter 
my ram specs are as follows :

OCZ 2048MB PC5400 DDR2
Memory Size: 2 x 1024MB
Memory Speed: 667MHz PC5400
Memory CAS Latency: 4-4-4-12
Memory Type: Dual Channel DDR2


i was just wondering...if this ram is supposed to run at a frequency of 667mhz...why does CPU-Z report it running at 334.9mhz ??? because it is ddr2 ram...should i multiply the 334 x 2 ? or is my ram currently underclocked ? sorry if this is a stupid question....but im kind of a noob when it comes to ram configurations..

It is because it is DDR. DDR is 667, actual speed is 333.5. Nothing to worry about.

cpuz always reports have the memory speed, as it is doubled for effective speed. Thats why ddr stands for dual data rate.

Just up the voltage to the max the manufacturer specs it at, and loosen the timings then push them puppys till they bleed.

Say they come stock at 2-3-3-6 these are tight timings. As in ;oosening, then going to 3-3-3-8 would be a good start point. Only rference in timings. Then when you achieve your final oc, then you can lower these one by one to see what remains stable to achieve the tightest possible at that given speed.

Edit: if your stock timings are 3-3-3-11 then try 4-4-4-12-15

Yes when he says lower he means actually lower numbers. Try 3-3-4-10 and if does not boot gradually go up, in order to overclock farther you are most likely going to have to loosen or raise your timings.
