Can't PPST beyond 914 MHz

post #1 of 21
Thread Starter 
So I've tested my setup in numerous ways, all with the same result. Can't get into bios/post at the magic number of 916Mhz for my ram. Now you might say, "You have the wrong settings" or "it's just your ram"

I've tried 2 pairs of ram. G.skill 2x1GB PC-6400 HK's and G.skill 2x1GB PC-6400 HZ's

Both had the same result. 914 works. 916 fails.

I've taken a lot of suggestions and read numerous guides, but for the life of me, I can't figure out why Someone else can OC to 1000 easily with this ram, while I can't get past this 914 to 916 barrier.
I've:
Gone higher with timings
Gone lower with timings
Changed memcore voltage
changed NB voltage, SB voltage.
Gone with 3 other people's "good" setups for timings/settings - None helped fix the problem.

And yes, Reset CMOS, of which, didn't help either.

I'm currently using my HZ's

This is a lot to read, and if you care enough to help, I'm willing to accept it and try it. Thanks.

Isn't there some kind of "static read control", disable that. When I had my old P5B, that always gave me trouble.

What is your voltage for the RAM, and have you tried using only 1 stick?

Current voltage is 2.25, I've tried 2.3, and same stuff.

yes, I've tried using each stick individually.

Have you tried different slots?

Is there another computer in your house, or a friends computer that will allow you to test RAM?


Also, you SURE its not your CPU holding you back right? I would put it on a 1:2 ratio, to make SURE your CPU isnt running out of juice

Because your CPU may be hitting a FSB wall or something. Just crank the divider to the highest one so it keeps your CPU at a low speed but RAM at a high speed

Intervention, you hit it on the head. That was the problem. 457 FSB is the highest my CPU can go.

Currently at 360x9 = 3.24Ghz
Ram is at 1080Mhz, and on sandra, that gave me 7440-something like that for memory benchmark, which is +300 from what it was before all this.

Thanks a ton man, for helping me figure out what was causing me from going above 914. +rep to the max.
