Overclocking CPU
I have an xp 2100 and a Asus a7n8x deluxe with 512mb DDR2100. On my old motherboard, i could get up to 154mhz fsb. on this motherboard, i am lucky if i can get 150 at 13x. this is supposed to be a great overclock board, but so far, i am not impressed. I just bought a volcano 12 so i know it isnt heat problems. I got it to 150mhz and 14x multiplier when i didnt have volcano 12 and it wasnt stable, but now i cant even go to 150mhz by 13x, when i try the computer says "memory test failed" before the graphics card starts, which also happens when i change the multiplier. I leave the memory settings alone because my memory is the most expensive thing in my computer, it is more expensive than my cpu. When it doesnt say memory test failed, i get the "blue screen of death" from windows xp, when i dont overclock, everything is fine.
Do i have to upgrade memory so i can get higher cpu speeds?
Thanks for your help

You also have to realize that overclocking can be a little like statistics: if you had 10 boards, 9 might be very overclockable but 1 is not. When people report how overclockable something is, it is NOT a guarantee that it can always be done with all parts. The only thing the motherboard manufacturer is guaranteeing is that it will work within the normal parameters. Overclocking is a hit or miss proposition at times, and if the odds are in your favor, you should be thankful.

Much like cpu's too. I managed to get the right batch of 1800+ for mine. I was pretty suprised when, with stock AMD HSF I was able to push it to 185 x 12, for a total clock speed of 2220.41MHz. Not bad for a cpu that's supposed to be 133 x 11.5 and 1533MHz.
Not everyone is that fortunate. And I didn't even keep it there. Although it ran stably and I could run 3dMark on it as well, I put it back down a bit. As of today it's running at 166 x 12.5 and is amazingly stable.

I have a P4 1.6a running at 2.1GHz, and another P4 1.8a running at 2.4GHz, both with stock HSFs. They both worked at 50% overclock, but after a half hour of compressing an .avi, locked up, so I stepped them down. No problems for the months that they have been running.

with the options in the bios, i can change the memoery speed seperatly, so i am going to try that. and i guess if that doesn't work i will have to upgrade memory. If i decide to change cpu as well, what is a good reliable site that sells the right revision?
You can run the memory clock asynchronous from the cpu clock, but you lose A LOT of performance when you do.
As far as reliable sites that sell the right revision, I really can't say. I'd check overclockers.com and see where they're recommending.

What about your CAS latency? If it's too low and you don't have LL PC-2100 ram, then that could be a part of the problem. I guess it's not that serious with slower ram, but when you get to PC-3200, you should watch out for CL3.
And radomir's right about the latency, if you're going to by PC3200, invest the extra money in a low-latency product in order to get the best performance.
Corsair TwinX-LL, OCZ PC3500 Platinum, Kingston HyperX are my favorite low-latency products, personally. But TwinMOS, Mushkin, and others all make it.

I'm running either Samsung, Micron, or something else at DDR200 with CL2. This is PC-3200 ram.
Maybe you could increase the ram's voltage to something like 2.6 or 2.7? That could help it run better at faster speeds.

mad_man22, thx for accepting an answer, but why the 'B' grade? Were we missing something? If there is more information you need, please let me know.
Here's the grading criteria, fyi:

How Do I Know What Grade to Give?
Although we use an A-C scale here at Experts Exchange, it works differently than, say, school grades. If one or more Experts' proposals are accepted as answers, they should usually be given an A or B grade, since they have taken the time to provide you with a working solution. If a possible solution is incomplete - ask for clarification or details before accepting the answer and grading it. People should not be given lower grades because of incorrect grammar or because you just accepted their answer or comment to close the question. Keep in mind, your question and any follow-up comments should be focused so that there can be a specific answer. The following is a good guideline to follow when grading:
A: The Expert(s) either provided you with a thorough answer or they provided you with a link to information that thoroughly answered your question. An "A" can also be given to any answer that you found informative or enlightening beyond the direct question that you asked.
B: The Expert(s) provided an acceptable solution, or a link to an acceptable solution, that you were able to use, although you may have needed a bit more information to complete the task.
C: Because Experts' reliability are often judged by their grading records, many Experts would like the opportunity to clarify if you have questions about their solutions. If you have given the Expert(s) ample time to respond to your clarification posts and you have responded to each of their posts providing requested information; or if the answers, after clarification, lack finality or do not completely address the issue presented, then a "C" grade is an option. You also have the option here of just asking Community Support to delete the question.
Remember, the Expert helping you today is probably going to be helping you next time you post a question. Give them a fair chance to earn an 'Excellent!' grade and they'll provide you with some amazing support.

well the only problem is, i cant aford the solution you gave, even though it was correct.
ASKER
also some how i managed to get up to 154 and 14x with my current setup, the amazing thing is, with my volcano 12, the temp on full load is just over 35C
If you want to fork out 150 bucks I got some RAM you can have. Kingston, might work with dual channel.
ASKER
the thing is, i dont even have 90 bucks for 512 of ddr2100
So why overclock the DDR you have? Your solution isn't top-notch, either. Seriously, your ram could fry up. All ram is damaged at different rates when overclocked. Please stop.
ASKER
yeah, it stoped working with overclocking, but works normally, so i need some better ram. i might get 512mb of kingston DDR3200 dual channel for around 150 bucks, once i get enough cash
