change mem speeds w/ A7V?

[Darth]

I'm just wondering if I'm missing something here..In the A7V bios 1005A, to change the mem settings, you have these options.

user define
7ns (143 2-2-2)
8ns (125 2-2-2)
by spd

I'm using 143 2-2-2, the user define option only lets you change the cas latency, not the mhz, so is there a way to change the mhz, if I wanted to try and hit 150 2-2-2, can you do that with an A7V? thanks..

The only way to increase memory speed with the A7V is to increase the FSB (cpu speed in BIOS) or to purchase PC150 memory. Keep in mind that raising the FSB also raises the clock speed of AGPcard, PCI cards, and hard drives. Your memory benchmarks at 7ns 143MHz should be very good with good quality RAM.

Actually, even buying faster memory won't make the memory run faster. You have to set the memory to run at fsb+pci clock, after which upping the fsb speed (which will also increase the pci bus speed) will significantly boost your memory's speed.

Also, you can check the mainboard information module in sandra, and it should tell you at what speed that your memory is running.

ok I looked at it in sandra, and it said the mem was running at 138, I saw that when I was changing the bus speeds, fsb 104, dram 138, so why does it give the option for 7ns 143, in the advanced chip menu?

Actually the memory speed is set in two places. The one that you're referring to is just where you tell your BIOS what kind of RAM you have. The second, in the Advanced Menu, actually determines whether the RAM runs at FSB or at FSB+PCI. You're just giving settings to the BIOS (in a simplifed way) so that it knows how to use the memory.

so what would be the optimum setting in the advanced menu.. user define, 7ns 143 or spd? I realize the dram freqency in the bios is at 138, that means its set for pc133, it raised with the fsb..I'm still not clear on the settings in the advanced menu

yep..overclock the fsb and you oc the ram...its how it goes..
