amd 2600+ overclock help

waterloo

How high can i overclock my amd 2600 thoroughbred???

I CAN't RAISE the voltage on my computer because my motherboard won't let me. It's a Sis 741gx-m
i don't know if i overclocked it but it's at 2127.9mhz and it's the sempron or something.

can i overclock it up to a 3200-3300 ish side?

mm first make sure which cpu you actually have, there's a difference in how to overclock each or how much each can handle. as you post now you could have 3 different cpu's (cores) ,a Thoroughbred A core, a Thorougbred B core or a Sempron core. A program like cpu-z can help you identify it.

The tb B core is probably the best overclocker of the bunch. to get to 3200 speeds you need to overclock your fsb too 200mhz, default for a tb B is 133mhz so it's quite a gap you need to cross. Most do need more than the default core to achieve these speeds so you might have a problem considering your mobo. If you want to find out your max fsb you can lower your cpu multiplier so clockspeed won't be an issue and then raise your fsb with 5-10mhz at the time and after every raise check stabillity en heat with programs like: mbm (motherboard monitor, for temps) 3Dmark03 and prime95 for stabillity.

When you found your max stable fsb you then can try to up the cpu multiplier with .5 at the time while keeping your fsb at default so it won't interfere. the same rules as with the fsb apply, take small steps and keep an eye on your temps and stabillity. When you reached your max multiplier you'll know the max cpu speed, now you try to go back to your fsb , raise it to the max stable setting you found and then raise the multiplier to reach the max clockspeed. do not try to use the max mulitplier and fsb together cause that probably is too much.

There are some programs that'll let your overclock from within windows instead of rebooting to go the bios each time. Such a program can save a lot of time cause u can run a benchmark or stability test each time directly after the increase without rebooting a lot. Programs that can do this: 8rdacore and Clockgen .

From my own experience and tb B can reach clockspeeds up to 2400Mhz on air and with 200fsb tho with a voltage increase. Since you apparently lack voltage options i'd guess and think you'll be able to reach, 166x13 giving a 2158mhz clockspeed. It's lower then your original but the higher fsb will compensate and even up your performance. Offcourse you can try to go higher but o'clocking is risky and can damage hardware so be very carefull, you'll void your warranty so when gone too far you'll have to pay up yourself

ps.. did i mention to be carefull ?

i know all about the overclocking things.

i don't think i going to overclock i dont need it

I need some program that can raise the voltage. because the computers voltage is to low.
it's al 1.6...

Well considering you have an SIS... When I had one it did not hav AGP lock... If I were you I wouldn't go tooooo high on the fsb w/o an AGP lock from stock 133 - 200 you might kill someting, youll notice gfx problems around 167... Just a lil tip I learned from my old SIS board, I oc'ed the fsb so high without an agp lock that even when lowered, the agp no longer worked. *assuming i fried the agp bus or something since there wasnt a lock*

waterloo

How do i do that agp thingy and how do i raise my core voltage?

PS. I'm 12 and i don' wanna fry nothing.. but i have
A.GOOD COOLing
B.10 fans
C.got fans on the top sides front and back

Core voltage can be raised in the bios, which is usually entered as soon as the computer starts up by pressing the Delete key. The agp lock can also be found in bios, if yours has it.
10 fans

GutterPunk

10 fans, you may have too much pressure in your case, do you have have jsut as much or a lil less air leaving then coming in?

also AGP lock would be in your overclocking section in your BIOS

waterloo

Ok.. HEre's the tHING i got tons of air going out, but to little in... what i am trying to say is

MY CORE VOLTAGE IS AT 1.60... and that's to little to power the compuer, i have a 440 watt power supply and it's not there the agp lock.
what program(s) can i use to raise core voltage, and fool around with the agp lock?

Thanks for the help guys

WisMerHill

None, your BIOS has to support those values, there's no program that can raise voltages higher then listed in your BIOS.

You can edit the BIOS with an editor and add higher voltage options, but thats not something to be undertaken lightly and requires lots of knowledge and skills. I would strongly advise against it but it's an option.

dude u dont understand..

i dont have VOLTAGE control, like i eally don't.
i don't got nothing
i went into power mangement eeverywhere and i can't see it.. i don't have it

WisMerHill

that's what i said, you need to have it in your bios else your out of luck.

you can only search your mobo's manufacturer support forum to see if you bios might have hidden options for voltage control, like pressing SHIFT-F2 to enable the hidden menu. If not then your stuck.

btw, why would you need more voltage, 1.6 is ok for a amd 2600, so why if you don't overclock?

if you want to get all the features so you can overclock (voltage adjustments, FSB adjustments, etc.), you gotta get a different board. preferably an nForce 2 board, if not a VIA board. Do NOT use an MSI board if you want to overclock. MSI boards do not overclock well.

You said you have a sempron or an Athlon XP? It would make a big difference if you found out which one you have.
