The computer does not start when overclocking memory?

Hi Habr.


I have memory OCZ Platinum DDR, with an operating frequency in 400MHz and timings of 2-3-2-5. And so the same mother ASUS A8N-SLI.

BIOS all the time defines the memory as 200MHz (though on assurances of people with a OCZ Forums, it is annihilated to 500). When you try to set the DRAM frequency to 400 — the computer no longer starts at all (not even BIOS initialisere iron). After you reset the CMOS everything is fine. The maximum that managed to get 333МГц. For my old system memory is the bottleneck, and the fact that it works in half-forces are not happy.


Maybe you need to change operating voltages, but I'm not special...


Upd.


By the way, in addition to the four main timings in the BIOS gives you the opportunity to exhibit 4 (don't remember exactly what). Of course, they are not where it says. Does it make sense to play with them, and where to find the options settings?

In the first place. The link shows the operating voltage 2.8 V, you put him out? The standard voltage for DDR1 modules typically 2.5 V.

Secondly. 400 MHz is twice the operating frequency. The link, again, is memory PC-3200, i.e. with a maximum bandwidth of 3200MB/s, which is achieved at a frequency of 200MHz, but because DDR data is transmitted not only front, but also from the decay clock pulse, compared to conventional SDRAM doubles the amount of transferred data, so marketers invented a new concept Ala the effective clock frequency, i.e. the equivalent of SDRAM. Here's to your memory real clock 200MHz and 400MHz effective. BIOS correctly identifies.

Probably 400MHz effective frequency, and the BIOS shows you is real, 200MHz. DDR also.

In addition, the memory OC is influenced by many factors. The quality of the motherboard, power supply, quality and condition of the power circuits (capacitors dry up and swell sometimes), the quality and implementation of the memory controller, a specific instance. If someone pursues to 500 (again efficient, real 250), doesn't mean you have too.

Well, okay? In fact, you dispersed it to 666, and not to 500, about which I wrote on the forum :) Only drive of the night at least memtest, then don't complain about strange glitches, software
