post #11 of 15
ok did you selsect the one to one setting then in your ram settings dont go by spd chang ethat to manual and set the manufacturer settings i think you said those were 5-5-5-15 or something like that and set the others folowing those to 6-42-10-10-10-10 which it should allready be at

try this and make sure that yoru ram voltage is set to 2.2 or whatever it recommends plus a notch and try that out see if it doesnt wanna wwork on ya


also what bios edition are yuou running, and you know that even with the new bioses a change a major one like changing the ram divider will cause the reboot thing alot of times so you gotta just let it run its course and it shoudl restart on it sown

diyerxa; you are pretty close to the settings I use, so why don't you try these settings:

__________

I've let all the power saving features on (enabled) so that my CPU even overclocked will consume less energy and therefore the frequency will change from 2.0GHZ to the full 3.0GHZ when needed/full load.

I use a 2:3 ratio (which gives me a 1000mhz RAM Frequency) but if you decide to run with a 1:1 ratio, then the DRAM Frequency will read 664mhz or a 4:5 ratio which will be a 835mhz.

Change the timings also to 4-4-4-12 (don't change the last 6 latency settings) with a 2.2v not 2.30v like shown.

I updated BIOS, and noticed some improvements in my OCing abilities.

I was able to boot in to Windows with the DDR freq. set to 1:1. But after about 5 minutes, the system crashed, aside from a couple other small errors.

I tried all the settings MADMAX suggested, and got a little further with the OC. Thanks for the help.

I am going to try some of the settings Nasgul has suggested.

The only problem is, it seems like when my RAM timings are set below 5-5-5-15, I experience problems. Manufacturer for this RAM is 4-4-4-12. I'll try that.

Also, it seems that the highest I can get my memory voltage to is 2.1, that's the highest setting allowed in BIOS.

I just updated to the latest version of BIOS available on the ASUS web site, 0806. Before I was using 0603 or something along those lines.

Thanks again for the help.

Well, if you have the P5B (vanilla), yes, the highest Vdimm you can use is 2.1v but nevertheless, that's more than enough for a 1:1 at 334mhz.

Which BIOS V. are you using? 0804? If so, I think those are not as good as the 0711. And just in case you want/need the 0711, I can e-mail it to you.

Okay, it's working.

I set the ram timings to the manufacturer specs. Left the bottom six settings the way they were.

I have it at a 1:1 ratio. 334:334.

I'm running prime95 torture tests right now. so far so good. If I encounter any more problems, I'll switch to 0711.

Thank you all for your help
