Still Confused With CPU/DDR Ratio - Page 2

post #11 of 29
you set your ram to 100MHz???

set it to either 133 or 166.

you'll probably find you can push your cpu speed further with RAM at 133.

my previous post about my settings is using DDR400 (same as yours) set to 133 in the BIOS.

when you push the cpu speed your RAM increases too...so... with mine my stock cpu is 200....I've taken it to 300...my RAM was set to 133 but with the boosted cpu speed it is now 196.2.

What I'm curious about is the fact that my RAM can handle running at 238MHz but if I set it to 166 in BIOS it spits the dummy.

I have attached my timings and stuff from my current settings.....advice on loosening for more power would be much appreciated.

Not necessarily, you can raise your cpu speed without raising your ram speed. You need to find the maximum values of each individually before you can set your machine up for maximum performance.

is there a special function I should look for to do this?? because when I increase my cpu freq my ram speed goes up too.

see to find the MAX individualy, i tested it , and what i found was, With a
Multiplier of x10,x9 AND
HT Multiplier to x4
i cant go beyond 212
and CPU/DDR ro 2/2.33
if i go beyond 212 then i need to decrease HT to x3 and CPU/DDR to 2/2,2/1.5 then i can touch almost 250-260, So what do u advise

Don't bother with that yet, find your ram maximum by lowering your cpu multiplier and turn up your fsb by 5 mhz at a time until you find your maximum. Once you do, you can either accept that value or you can raise your Vdimm and try to go higher. You can also loosen the timings on your ram to push higher. Once you find your ram max, put your ram on a huge divider and turn the cpu multiplier back up and find your cpu max by raising your fsb 5 mhz at a time. Again, when you find your limit, you can try to raise higher by increasing Vcore.

I'm not clear on what you're writing, are you saying that your ram can hit 250 to 260 or your fsb can?

your RAM speed is still well below what it would be capable of.

try increasing the RAM frequency to 166 and see how you go

(may not work but it seems overclocking is trial and error)
