overclocking...read and responde!

bobynan · 03-28-2003, 02:25 PM

I try to understand how this"overclocking" works....
First...i had a new machine, XP2400+/133FSB and A7N8X Non-Deluxe, 2x256MB PC2700 CL2.5 Kingston...
If i want to overclock my proccesor, I need to increase the FSB and lover the multiplier...or keep the multiplier the same(15x) and increase the FSB?
What about the maximum what i can push my system?What can get wrong?
I have a Volcano 9 Fan and it works great...my idle temperature is around 33 C...I think it's pretty good...and another 4 case fans...
Just try to write something and responde me...Thank, GUYS!

i need to increase some voltages somewhere?Memory or CPU?

bobynan · 03-28-2003, 04:25 PM

I try to overclock without increasing the voltage for either CPU or Memory to 145/145...and I stop!

for my previous benchmark(GF3 Ti200 128MB) with a score of 7925/8616 to 8176/8919( with my video card in normal and performance mode).
I wonder if i can get more from my CPU!
And all this without increasing the CPU Fan RPM(volcano 9 with a variable rpm from 1200 to 5200-now with 3300RPM)

bobynan · 03-28-2003, 04:32 PM

I try to go directly to 166....just a big NOTHING!
I reset the bios in order to start again my machine....i need to try between 145 and 166..who knows?

Overclocking can be complex, especially when you have a superflexible mobo/cpu combo like yours.

First step is to get the last bios for your board - at least 1002. This is needed to fully unlock your cpu.

The next step is to find the limit of your CPU, keeping everything else in spec. Set your memory timings to spd and fsb/memory bus to 133mhz synchronous. Up the CPU multiplier a step at a time, booting into windows to run a full gamut of tests. Usually 3dmark is a good stability test that doesn't take too long.

Your CPU could top out anywhere between 2100 and 2400mhz at default voltage. Once it starts to get unstable, just up the voltage in small increments (usually to 1.7, 1.75) until you reach 1.85v. What ever speed you can maintain perfect stability at with using 1.85v should be considered your CPU's maximum. Only go beyond 1.85v if you have water cooling or similar set up.

Once you've found your CPU's maximum, next step is to find your Memory (or chipset) limit. Lower your CPU multiplier to something like 9 or 10 and start your ram at 166mhz synchronous with the fsg (also 166). Set the ram timings to SPD. No just increase your FSB/ram speed in small increments until it get unstable. Make sure your CPU is well below its known limit. You should reach somewhere between 180 and 190 mhz with complete stability. You may want to speed up your ram timings (lower numbers) and see if you can still acheive total stability. The generally lowere overall memory speed maximum, buat may still be worth it. Play with them.

Finally choose a CPU ratio that maximizes your total CPU speed when coupled with your highest stable FSB. For instance, if 185mhz at 2-2-2-6 timings was yoru memory max, try 12.5 as your multiplier for approx 2310 mhz (at perhaps 1.8v).

Hope this helps a bit!

first thing..THANK YOU NOAH!!!!!!!!!!

Now...to find the maximum power for my cpu I need first to increase the multiplier?I already run 15 x 133 FSB..or I need to increase the FSB and keep the multiplier the same ?I'm confused..
I hope you gonna write again and tell me more about this...
You think I can go that far?185 MHz FSB or more?For a 133FSB CPU?

Noah_abx · 03-28-2003, 06:33 PM

I usually start by keeping the FSB and memory synchronous at 133 and increasing the muliplier. First, try 16x133, then 16.5x133, then 17x133 etc. I think you can go up to 18. If any of the higher mulitpliers don't work, you can start to increase your FSB. As long as you keep the ram timings slow and you are using pc2700 ram, you can be pretty sure any limit you hit will be the cpu as long as you are below 166mhz fsb/ram.

Does that help?

Sorry for all the typo's above (I had to **** wicked bad and couldn't stick around to edit it).

bobynan · 03-28-2003, 06:55 PM

offcourse..THANK YOU AGAIN!!!

I'm gonna try..i have something to do right now but soon..in 3-4 hours or tomorrow morning..i'm gonna have some results..thanks again and i hope everything will be fine...and i'm gonna keep you informed and i hope no more questions....
THANK YOU AGAIN!

bill1clinton · 03-31-2003, 07:03 PM

hey, noah?? so are you saying that with the new bios 1002 and 1002a, my 2400+ is fully unlocked without any other modifications?? thanks.

bobynan · 04-02-2003, 01:24 AM

I just try to overclock my processor..
I took first step..i increase the multiplier to 16..16.5...17... everything look fine, 3DMark was just fine..stabil..and that was the maximum because that is the max multiplier i have in my bios(1001.E)
In Sandra 2003...i haved this results:
133/133/15_______fsb/memory clock/multiplier
cpu 7454/3016
multimedia 11040/11539
memory 2030/1060

133/133/16

cpu 7987/3204
multimedia 11807/12378
memory 2022/1958

133/133/16.5

cpu 8223/3332
multimedia 12159/12779
memory 2023/1964

133/133/17

cpu 8552/3416
multimedia 12560/3520
memory 2023/1970

Hei guys..this is the first step..i'm gonna keep you informed but i need more time..
NOAh..what you think about this....?is good enough or not?what you gonna do next?if it was your comp..?

bobynan · 04-02-2003, 01:25 AM

..i forget something..the temperature on my cpu was stable..around 33degree celsius...ok..see you soon guys!

bobynan · 04-02-2003, 01:44 AM

i try the next step...i lower the multiplier to 11 and increase the FSb to 150/sync with the memory 150(i have pc2700..so this it's suppose to be ok with the memory chips)
NOTHING..it not even start...
I reset th e bios and load again the "normal" settings..
The best thing I ever reach was 145/145/15....FSB/Mem/Multiplier
Some sugestions?

Noah_abx · 04-02-2003, 10:22 AM

Well, the CPU is good and probably could go faster, but it looks like somehow your ram is limiting you. What RAM timings are you using? Do you have a nother stick of ram available to test with? The system should handle 166mhz no problem.

bobynan · 04-02-2003, 12:33 PM

right..i have two Kinston pc2700(166)..if I keep the fsb to 133...or 145 maximum..i can use the memory at 166..no problem... so the modules are capable to handle 166...maybe more..but where's the deal if i can't increase the FSB more then 145?
I read mesages here everyday... some people sad they overclock to 185(without special cooling system..)and more then 220 with water cooling system..HOW?
I'm not tryng to destroy my parts or my computer... i try to see with my own eyes how this is working and to learn... it looks like something is wrong..and i really don't know where...
What you think i can do now?I can try something else?

bobynan · 04-02-2003, 12:36 PM

I think my timing are 6/3/3/2.5
I.m pretty sure if i try to lower the multiplier and go with the fsb to the maximum 145..my cpu it will work..why i can pass the 145 barrier?
