Help with barton 2500+ overclocking

[waazzuup]

I'm a newbie to overclocking, but I have been searching through some old posts, but I still have some questions. First of all, unlocked means that you can change the multiplier - right? I can change the multiplier. I ordered a 2500+ on 09/24/2003 from newegg and I have been running it at the correct settings, but now I want some more speed.

I read that if I want to make it a 3200+, that I just need to change the fsb to 200 and possibly up the voltage. I set it at 11 x 200, and I moved the voltage up to 1.75, and windows xp would load up, but then it would freeze at my desktop, or the monitor would just turn off.

Right now I am running at 12.5 x 166 and it seems to be very stable. Asus Probe says my cpu temp is 42c and I think the bios says 44c.

My ram is 2 sticks of 512mb Kingston HyperX 2700. Should any ram settings be changed?

Anybody have any other ideas for me? I would really like to get this up to a 3200+. Thanks for the help!

What Asus motherboard do you own? In order to do 3200+, you need to leave the multiplier at 11 and set the FSB to 200mhz. Not all chips will do 3200+ stabally, no matter what. What kind of ram do you have? Have you tried setting your ram speed to 83% in the bios when you set the FSB to 200 ?
Good luck

yes, unlocked means you can change the multiplier as you please. you ram is probably holding you back from running it at 200x12. you shouldn't even need that much voltage to do that. try easing back the ram timings to see if you can pull 200 with it. also try 166x13 to double check if its your ram or your CPU keeping you for reaching 2.2ghz or close to it.

you should def be able to hit 3200 and beyond. keep pushing the multipler at 166 and voltage. watch your temps, see how far you can go with that core and cooling. then work on getting the FSB up.

My Motherboard is an ASUS A7N8X

My Ram is 2 sticks of 512mb Kingston HyperX PC2700

I haven't changed my ram speeds at all. To be honest, I'm not really sure what I should change them to.

I'm pretty sure I can't go past 12.5 for the multiplier.

What is the highest my temps should be?

What do you mean by keep pushing the multipler at 166 and voltage? Just keep bumping it up? Also, what should my ram be set at?

the bartons when overclocking generally like to stay below 50C for stability, but anything below 80C is safe for the core. just make sure things don't get out of hand.

i meant to push the multiplier and keep your ram at its normal speed in order to see what the core can do. once you know the limits of the CPU you could work on getting the ram speed up. your ram is only meant to do 166,so if you want to push it up to the speeds you want you will have to change the ram timings a bit if you want to get that high,if at all.

What would you recommend that I set my ram settings at? I really don't know anything about what they should be.

well thats totally dependant on what the stock settings are suppose to be. from what i can see, its 2-2-2-5 1T, so try 2.5 3-3-3-6 2T? just knock it all up a knotch

Right now I'm at 12*190 and I haven't had any problems yet. My voltage is at 1.7. I'm going to keep playing with it. Asus probe says 44c, and the bios is probably about 49c. Which is more accurate?

Also, I didn't touch the ram settings yet. You gave me 5 numbers, but I only saw 4 settings. Here is what they are right now...

SDRAM Active Recharge Delay - 6
RAS to CAS Delay - 3
RAS Precharge Delay - 3
SDRAM CAS Latency - 2.5T

I think either my friend set those, or they somehow reset to those. Like I said before, I'm not really sure what those #'s mean.

bump. Anyone know about the ram settings?

Those numbers look pretty conservative or "relaxed". When you have relaxed timings, you can usually run your ram at a higher fsb. There are different ways to achieve speed when overclocking. You can lower timings on your ram. You can also use more relaxed timings and get a higher overall fsb. It takes a lot of experimenting and benchmarking to find the sweet spot for your particular setup.

Here's a link with more detailed info on the various settings.

If you want to see what options you have, try cycling through them in the bios. The first number (6) should probably be left where it is. The 6 is a good number for fsb of 150 and up (IIRC). You might want to raise it to a 7 if your fsb gets to 200. The next two 3's can probably be lowered to 2's, but this will make it more difficult to get higher fsb speeds. The 2.5 can be lowered to a 2, but again you will probably have trouble getting higher fsb's. Alternatively, you could also raise it to a 3, and have better luck at getting high fsb's.

the ram is 166mhz so at 200mhz try a cas 3,3,3,10 and work your way down entill you get errors, then bring it back up one notch.

Thanks guys. I'll play with it more tomorrow.
