Hi all, I'm new to the overclocking business and i have read a few guides and im preety sure that i now understand the basics of it all. I was mainly after a few figures for the settings that people with a similar setup to mine have used to run their cpus at and have been stable etc. My hardware is as follows:

A64 3500+ Newcastle core running at stock 2200mhz
1gb Geil Ultra PC4000 ram
ASUS A8N-SLI Deluxe mobo

It would be nice to get it running at around 2400mhz+ :)

Any help would be much grateful!

Thanks for everyones response, been a good help! I have just tried to play with a few settings in the bios and used the following settings:

HT Freq. - 4x
Cpu Freq - 220
Cpu Multiplier - 10x
Cpu Voltage - 1.45v

Which should give it a clock of 2200mhz (same as standard just using different values) but when i tried to rebbot i got a POST saying CPU overclock failure:(???

I was intending to try this and then gradually step up the Cpu freq.

Have i done something wrong/stupid?! I have a sneaky feeling it could be the voltage??
 
I have sorted the voltage out now, put it back to 1.6v and now it works ok at 2.2ghz and my ram has also gone up to 220mhz.

Gonna gradually build up the frequency to see what i can get put of it :p
 
Right im slowly stepping up the cpu freq and i have got it running at 2.3ghz now, but it is slowing my ram down??

As soon as i go over 220mhz it drops it to:

225 * 10 = 187mhz?

230 * 10 = 191mhz?

but at 220 * 10 the ram runs at 220mhz

Anyone have any suggestions as to why its doing this
 
Have got it running nicely @2.4ghz now, everything seems preety stable. have been testing it for a while using prime and seems ok. Thanks for your help everyone :)
 
Ye i figured that out after playing around with a few bios settings :D

I had the max memclock set to auto so it was running the ram at 333 like u said, put it back up to ddr400 and the rams running at 240mhz now
 
just posting a link to cpu-z verification:


linky


I'v got it running at 2415mhz using 230*10.5.

Do my ram timings seem ok to everyone ?

been running it for a few days now seems stable no errors with prime95, and im still using stock cooling :p

will purchase a freezer 64 pro soon tho and push it some more

here are my results

I was lucky cuz someone basically told me what to do......

I know I know I have to learn its in my best interest after....

Meanwhile I noticed in everest it states my system has been overclocked 10% how good is this on the overclocking scale?

I mean what percentage to the experts overclock to?

Thanks for your help

hey what temps is it running at? are u also running stock cooling?

i'v managed to push mine to 2.5 now but i think im going to get a freezer 64 pro on it soon, then i'l try and push it further!

10% is ok, you've basically got the performance of a 3700/3800 cpu (without the larger L2 cache!) i think u'l be able to get more out of it tho :D

what psu and ram do u have tzu??? whats your cpu temp at 2530mhz?

Hi mate, sorry for the delay in replying only just read your posts

glad uv got it all sorted now!

Mine runs stable at 2.53ghz (230*11 @ 1.6v) and also im just using the standard heatsink and fan with four case fans!

I have an enermax noisetaker 485w psu and 1gb Geil Ultra pc4000 ram.

The cpu does run quite high temps when under load, late 50s normally, but then they are the 130nm chips so they run hotter anyway even when not overclocked.

Why cant you get yours running at 2.5? What kind of errors do you get or is it just not stable?
 
not if your using a ram divider... i had a problem with prime where it failed instantly and that was when my ram went to 240mhz! but then i took it back down to 230mhz and it was alright!

What prime test are you running when it fails?

I think you'd be best to run a small fft test first to take ram out of the equation and then if it still fails then its a cpu failure, if it doesnt fail and runs ok then try to run the large fft and see what happens then?

also what spped is your ram running at with the divider?
 
run your ram at its default speed of 200mhz and then see what hapens?

there is no need to slow your ram down to get stability like you said, you just have to use a divider to stop it from going over its max memclock, probably 200mhz for pc3200? i.e. if your using a 230fsb then use a divider so that your ram runs at 200mhz instead of 230mhz as it would running it at 1:1,

hope that helps, then see what happens when u prime it!

let me know
 
I just set the max memclock settings to ddr400 in the bios

i have left the ram voltage to auto and the cpu voltage is 1.6

because i am using 230*11 the ram runs @ 230mhz, because i am using 1:1.

like i said my ram didnt like going above 230 but that not a problem as im using 230*11 :D

i reckon u'l be alright using a divider to keep your ram at 200
 
forgot to mention currently running large fft test in prime and no errors so far, been running for bout 30 mins, and my temps hover at 56/57!

i reckon u'l be ok running the voltage at 1.6v and then the temps should be about the same as mine and not touch the 60 mark!
 
what speed is your ram? if its pc3200 then your max memclock should be ok at ddr400, if not then use ddr333.

also if you were to use ddr333 then you could try using 250*10 so that it would speed up your ram but keep the cpu clock speed the same at 2.5ghz.

Also what have you got your htt multiplier set to? you have to make sure that stays under 1000?

Firstly though i think you should try small fft test using 230*11 @ 1.6v and see what happens then. this test doesnt use much ram therefore will test just the cpu stability!
 
o well mate, 2475 is still a good overclock from the standard 2200!

u'v got to remember there newcastle cores aswel so that makes them less overclockable, plus it could be anything stopping you getting 2.5 such as mobo, psu etc.

have you run any benchmarks? like prime benchmark or super pi?
 
nice one then thats alright then.

when you have finished testing it you can run a benchmark in prime - Options... Benchmark... and it will save the results in the results.txt file in the prime95 folder.

And if you google "super pi" and download it (not a very large program) then we can compare results... i cant see there being much difference between mine and yours :)
