Asus Crosshair Mobo Help

post #1 of 8
Thread Starter 
I Have the Crosshair with an AMD X2 6400+ at 3.2 Ghz. I've tried to overclock the Processor but after 220 on the Referance clock my computer won't pass post.

I have my memory at 5-4-4-15-26-2T witch is the EPP profile, at 800Mhz. Do I need to lower this even if the memory is rated at 800Mhz.

I'm aslo wondering if the bios has something to do with it. I have the latest which is 1103, but i've seen people with 0802 or lower. This leads me to believe that updating the bios is not always good.

Any help would be awesome

I know The Duke has/ or had the Crosshair in the offical Corsshair thread, if you can help.

DId you lower the CPU Multi down from 16X? 220X16 is 3520 and I am pretty sure that chip doesn't like that

Yeah I lowered it to 12, and raise the bus speed to 290. I blend tested this bus speed for at least 12 hours in orthos so i know the motherboard can handle this.

I've even followed durch's guide to AMD overclocking.

290 is above 220 so what CPU multi were you using with 220HTT to cause it not to post?

Sorry I meant 290 not 220. Well heres a screen shot of CPU-Z

I was trying to get 3.520 MHz with a 290 referance clock which is 290 x a multiplier of 12. This gives me a clock of 3.480 MHz which is close but didn't go with a multiplier of 13 since this would give me a clock of 3.770 MHz (Don't want to push it that much yet)

If you look at the screen shot I have it at 3.5 GHz at 1.48v I could probably lower the voltage actually, but this is at a bus speed of 220 x 16, which is running fine at the moment.

I guess what I don't understand is does the computer perform better with a higher bus/referance clock speed, or no.

What I want to do is max out my memory, and have the processor work harmonious with the Memory and what not.

To be hoinest I think I have this all wrong so I'm at a dead end because I ran 3D Mark 06 and got a score of 6634 with the settings you see in the screen shot, but if I leave everything alone, and have a referance clock of 200 x a multipler of 16 and leave my memory timmings the way they are then I get a score of 10654 or so. I'm wondering why the drop in score if I overclocked.

My goal is to get a higher score in 3D Mark like maybe 12,000 or more if thats possable, but I know i'm also limited to the Graphics cards aswell, but I still don't understand the drop in score, plus is 10,000+ a good score in 3D Mark, or is that just wishful thinking.

Depending on what you do with your computer depends on if it is better just to have a higher CPU greq, or have a higher Bus link. I always thought my computer seemed more snappy with 250MHZ + on the HTT link, with the same CPU as you oc'd to 3.375 I would get just over 11K in #D Mark 06, but I am using a single 8800GTS 320MB not sure if if SLI'd 8600's would out perform that or not.
As far as a lower core with an overclock.... that leaves me scratching my head. the only thing I can think of is if you lowered your ram speed by settig a divider and forgot to turn it back up. BTW our computers are almost identical, same ram( i have the 2x2gb version) same CPU, same MB, and same HD config so you should defiently be able to break 11K i would think.

Hey. I'm having the same challenges. Yet, my Mark 06 is at 12900 @ 1650x1050 resolution. 12,000 plus IS possible.

I am only able to overclock my processor at 5% for 3360. I can get 3440 yet my system is unstable...At the voltages, multipliers, and Bus Speed 220x16 @1.48; were you able to get a stable system at a higher speed?

My system is similar to yours; but I have 4-4-4-12 Ballistix memory at 840; yet I can only get my system stable at 210x16.

At a 220 bus speed mine won't even post.

try using higher reference clock and lower multi.

also, i've run my X2 5000+ BE @ 1.55v before, although it yielded no better results than at 1.5v. try upping the voltage on yours, too.
