Need Suggestions On Oc A7n8x Del. 2500


Recommended Posts

Running out of ideas need some suggestions (Read SIG)! I got my cpu @ 11x200fsb and up the vecore in small amounts. When I got to v1.75 I gave up. The system boots no problem but the video crashes to desktop and I can't figure out why. I tried a registry hack for Agp hanging and that helped some but the video in 3D Mark on the Matrixs was freaking out. :O My temps are good the highest I have ever had on this cpu 45c and my memory time is 6,2,2,2t. I want to run Prime95 but what's the point if I already no a problem is there. :lol:

Please any suggestion would be great, Thanks. I have been having this problem for some time as you can see from my other postting..

ok anytime you up the fsb you change your agp ratio, on the Asus board you need to lock the agp at 66mhz and not have it on auto!

that should help you with the video problems your are having.......just remember that by uping the v-core your adding heat and stress to the cpu, up the v-core with moderation!!

I have the agp locked at 66mhz! And temps are 36c idle and 43-48c L fan Med.

I found the problem and investigated it further. I found that raising the fsb to 200 and droping the multi to 10.5 (cpu) the vedeo would run through two test of 3D Mark then on the third test it would crash again. I then raised my timing to 6, 3, 2 , 2t from 6, 2, 2, 2t (system memory) and the video had become more stable. I''m now stable @11X200 w/1.75vcore. My question is, I find from the benchmarks running 3Dmark w/a higher vcore and mem timing the video stopped crashing, could it be the "Fast Right" is the bottle neck with overclocking? The reason I figure this, is because the volts should not have had that much of an influence over the agp. Has anyone come across this before?

The reason I ask is if you turn of "Fast Right" should I see less vcore, has anyone any info or had that expereiance how that affected the performance of video and if there was a lower usage of vecore? The 3D mark would crash with every vcore raise until 1.75v but until I raised my memory timing. The jump in vcore seems a little high with the outcome is my point. savy!

its not your video card that is crashing when you are 3dmark benchmarking. its you cpu. when i oc too much and run 3dmark its not my vid card that will cause the random reboot. maybe i dont understand your question though cause what im saying is obviouse stuff.

ie. if your vid card is running fine with the cpu at default then your vid card is running fine. o/c your cpu and you get a random crash/reboot, there has only been one thing changed in your system and that is your cpu. a agp card is not going to crash if a cpu is "too fast". hope that helps, but as said before if you o/c and crash try 1. upping the vcore 2. bring the o/c back down a step.

Your right about the volts guys and it not being the vid. I just figured it was the fast right causing the problem because it seemed a very high volt increase. I increased it in small amounts .025 @ a time. I got to 1.775 and the vid stoped crashing and ran great but then on Prime95 the test would error. So I increased the volts in .025 until it would run the test properly @ 1.825volts now and stable. :P I will run prime for along time to make sure. Thanks for the help and sorry for the confusion on my part ;)

cool... keep an eye on those temps when running at 1.825v. how long have you had your setup? if its only a week or something after another week or so then try bringing the volts down and see if it runs stable. i use to run at 1.75v for a stable 200 x 11 but it now runs stable at 1.25v and a lot cooler.

Man 1.25 now that is a super processor..lol

 

I have had this puter together for a month and half. I was working the bugs out slowly and the noise. I removed my slk-800, for the volcano, so I could hook the fan into my bay fan controler to get some peace. :D

So after having your system clock for some time with a higher vcore you where able to lower the volts at a later time and get it stable. I have never heard that before. I have been running Prime95 all night and part of yesterday about 15hrs total so far and it rocks.

I thinnk I have reached my goal of 200fsbX11 anyway for now so thanks for the suggestions everyone.

 

I also have a question for the People who know Prime 95, what is more stressful running the ( primality tests ) or the ( cpu torture test )? How much of a stress difference is there between the different test? The reason I asked is I was running primality all night and it really loded the cpu and I was wondering how much more the cpu torture test will do. This is the first time running Prime95 I have been running Sisoft Pro. Sisoft Pro didn't do shi* compared to Prime95.
