Switch Mobos and now i have -400 mhz o/c?

hey all,

I had a flaky abit nf7-s mobo w/ my 1700+ @ 2.1 ghz stable

i switched out the abit for a new asus a7n8x and i cannot get it above 1.7 ghz

More voltage doesn't do anything, it refuses to post and/or freezes up @ post screen. ..

now while the mobo was flaky (didn't recognize my wireless card) the cpu was 100% stable for a few months @ 2.1 ghz.

Why would a switch to an asus board lead to a - 400 mhz o/c...

thanks guys!
 
Would you like some cheese with that whine.

for what is worth, i started with the asus and it wouldnt run my 2400 stable at 200mhz fsb no matter how high i cranked the voltage.
i swaped it out in favor of the nf7-s which allowed me to run the 2400 at 211 at stock voltage. the only diff was the mobo. don't know what else to tell you.
 
You bought a 1700+ and that's the speed you should be getting.

anything over that is pure gravy,so your chips isnt the best.

You got what you paid for nothing more.

Sound like your cpu was flaky all along & not a good overclocker,getting a new board just confirmed it.
 
actually budman. NO , it was "flaky" b.c it wouldn't take my wireless card.

The cpu was stable for months @ 2.1 ghz. i can verify this b/c i run distributed computing that uses 100% of the cpu resources 100% of the time. and it's also used as a gaming pc. So i am sorry budman but no, the chip is not FlAKY as you think it is. This chip did 2.4 ghz on Water prior to me buying it.

Have a nice day budman
 
OK,

i am requesting help here. Budman please leave this thread as my problem is no closer to being resolved and instead you are just aggravating others. This is not your personal flame thread so please leave so my problem can be looked upon by ppl that actually would like to help me out.

thanks
 
I have a feeling that it has something to do with your memory timings. I'm running an A7N8X Deluxe 2.0 and it took me quite awhile to get the knack of overclocking it. I'm running generic PC3200 (Hynix) at 2.5-4-4-11, and it took forever to find those stable timings. The easy way is to leave the memory performance at "optimal" in the BIOS, but that won't give you your fastest possible timings.

What I would do is this:

If you have PC2700 memory, try it set to "optimal" and leave the FSB at 166.

If you have PC3200 memory, again, set to "optimal" and leave the FSB at 200.

In my experience, most of the stability problems with this board have to do with the memory. Also keep in mind that the board can't run at a multiplier above 12.5 without doing the wire trick.

Good luck resolving this.
 
I have some experience that might be helpful.
I have a A7N8X Deluxe here, I had to update bios to get it stable at all.

I have two 1700+ chips - one in the Asus mobo and the other in an Epox 8rda+
I have HyperX PC3200 in the ASUS in dual mode and Twinmos PC3000 in the Epox (not dual).
The fastest stable speed in my ASUS is (1:1) 175fsb x 12 = 2100mhz @ 6-2-2-2.0 timings
The fastest stable speed in my EPOX is (1:1) 224fsb x 10 = 2240mhz @ 3-2-2-2.0 timings

What multipliers and memory timings are you trying and how good is your ram?
What bios version?
 
i have 1 x 512 ( no dual channel 🙁 ) stick of corsair xms pc3200. it is running @"optimal" settings of 2.5-4-4-9 @ 2.7 V

fsb is set to 200

i'm trying to run 9.0 x 200 and it just hangs. before i was doing 10.5 x 200 @ same voltage
 
good idea.

for another system i build for someone the first slot didn't work w/ the memory ( i had 2 x 256 sticks) using the same mobo.

You just reminded me of this.. i will try your solution!

thanks man!
