Problems after following "Complete guide to OCing"

Recommended Posts

I just finished building my new rig as posted in my sig. after i got it up and running and installed xp i followed the directions in the thread complete guide to overclock. I first did the part where you find the max CPU speed that was stable. after finding that i ran several of the tests posted in that thread everything was working great no stability issues at all. i left it that way for a couple of days not having any problems, so i decided to carry on with the next step in the complete guide thread.

 

So when i go to overclock my memory i start with the first speed available other than "auto" in the bios which happened to be 100mhz ran memtest worked fine machine booted and was stable. i then bumped it up to 120mhz ran memtest was fine. after that i moved it up to 133 mhz and it would not boot or do anything, finally i moved safe boot jumper to safe boot and had to remove one stick of ram to boot the machine. took all the bios settings back to factory. the machine booted but corrupted my xp boot cfg file so i reinstalled xp. once i finished that i reclocked my CPU to the setting where i ran it on all the tests and for a couple of days use, but this time my computer would just keep rebooting after the detecting all the hardware. so i went back through the cpu OC process and now my processor max speed has decreased by 400 mhz and i'm still having a B.S.O.D. once in a while where it reboots my machine at the lower OC speed. and i can't get my rig to boot on anything but the stock ram settings.

 

I've searched and searched on these forums for a similar problem and haven't found any answers. Please Help.

 

Thanks

Zane

Read the complete guide before you use it. There are a lot of other referenced works that support it. It took me a couple of months to read and apply, then I started actually learning and understanding. You will find that one major problem will be Corrupted BIOS and that requires using the Clear CMOS procedures. Early stages of learning OC result in many learning opportunities of the Clear CMOS procedures. Have fun. Welcome to the Street.

Madu, you do not have to keep the mem divider at 1:1, thats just silly. If you use budget ram, or ram that dont OC too good, you have to use a divider to get the best OC. Divider make very little performance difference

Divider decides your ram frequency.

You said you put "auto" setting.. thats why i asked..! I didnt see a "auto"setting in the FSB.. Maybe I'm wrong..

If you lower by dividers, what the purpose of doing the test.. what you want to do is check your ram's max frequency. So it doesnt matter by lowering with a divider. Is your ram running lower than 200? If so i'm sorry for my mistake.. I thought you are upping more than 200.

thank you all for your replies.

 

one of my problems i figured out was i needed to move my dimms to slots 1 and 3 to get dual channel instead of 1 and 2. but that still hasn't fixed my problem with not being able to bring my FSB up above 230 when it was very stable at 530. i now have my ram at 190 and LDT at X4.0 which seems to make a difference.

 

I'll try the clear CMOS maybe that will fix my problem with the CPU speeds.

oh yes yes madu means that u need to find the max speed ur ram will run at on 1:1 on the timings that u want

because dividers will work off that speed, and the lower the divider, the lower the max RamBus is for ME

Have you changed your memory timings at all? If you are trying to find max memory speed with everything on auto, that's going to be between 220 and 225 in most cases. There is a link to a good page that explains what every timing does in the OC guide. Read it a couple of times. If it doesn't do you any good check the OC database, find someone using your memory and use there timings and start pushing up the FSB with those.

 

Which Geil Ultra Platinum do you have. PC3200, PC4000?

i did change the timings to the ones in the article cited in the complete guide to OCing. which for my brand Geil Ultra-Platinum PC 3200 2-3-3-6. Setting the timings instead of using auto didn't seem to make a difference.

 

When you say should run at or around 220 where can you get that because in my bios i have the option to go from 100-200 (100, 120, 133......200). Sorry I'm a noob and showing it bad.

What I meant was that most RAM at stock timings will only run up to 220 FSB and then you have to start changing timings. Not just the base 4 timings but all of them.

It tells you the MHz in memtest. you are useing memtest right ?

1 Last thing, that I saw, not sure if anyone mentioned this but what brand is your PSU, and also it's recommended to use a 480W minimum on these boards.. I could be off =P
