Unlocking Multiplier

[Zak33]

Rave is right....he has an uncanny knock of being right Cheers Rave man....put me straight

You're cpu is locked......just up the FSB a bit at a time.

DOnt hold out too much hope on a 200 speed tho ....its possible, just not likely

Download this handy tool and it will tell you everything you need to know.Apart from whether its locked or not.

I don't think it is locked after all - I went onto that menu on the bios (see about 3 posts ago) and it said it's currently set at H/W. Could someone tell me what that is please.

Also, there's LOADS more options from 7.0 x incrementing every 0.5 x up to 13.0 x. How far is it safe to go, and what is H/W?

Thanks

[Zak33]

I have no idea what H/W is?

[ajbrun]

neither do i - I've go to go to work now, so I'll look in more detail later.

Can anyone say how much the mutiplier should go - it seem that it isn't locked, even though i only brought it a few months ago

[Zak33]

have you TRIED changing it?

It will sohw in BIOS as adjustable...but will it WORK?

If it boots with the new speed...youre in luck.

If it boots at the original speed.....you are in luck cos although its locked you havent got to reset CMOS.

If it does NOTHING and the PC is dead, you need to find out how to RESET CMOS....on the whole, you find the jumper, you unplug the power lead from the motherboard, you swap the jumper over and leave it for a full minute (count 60 ....a real minute) then you move the jumper back and then plug back the power lead and reboot...

and reset all the BIOS settings again to where you want them

[ajbrun]

It seems that you were all right - I tried to change the multiplier, and it went dead. So I've now changed the fsb to 200. If it crashes, or anything goes wrong, I'll bring it back down to 166.

Thanks for all your help

I went onto that menu on the bios (see about 3 posts ago) and it said it's currently set at H/W. Could someone tell me what that is please.

I think H/W means "HardWare". But does anyone know why it would say that in the multipliers part of the bios?

[ajbrun]

I've just checked the temperature, now that I've changed the fsb from 166 up to 200 MHz. It is now at 48C. Is this safe? All that will happen uf I do change it back is that things will load very slightly slower, so should I change it back?

[Applecrusher]

No. 48C is an ok temp...

About 60C is where you may start having problems...

[GreenPiggy]

Have you stress tested it at all at the new speed?
Thats a good chip if it stays stable.

ok m8 a little guide to OC'in this little bad boy

1.Multiplier - First you need to under clock it to test the locked/unlocked status of the CPU. It wont give you the high speeds you want, but it will tell you if you can change the cpus multiplier. Then step it up while increasing the FSB in small dozes. Do a system check using sandra or another benchmarking program to burn in the new settings. Then burn it in using a benchmarker for 24-48 hours when you hit the max combination of FSB and multiplier. The burn in is important because it will tell you if your system is going to stable.

2.FSB - This is where you can do some some manual changes in performance of the CPU. I found the Bartons to be unstable at 200FSBx11.5+ if you dont up the volts on the memory and cpu. Better to aim for 166x11.5+ or 200x10-10.5.

3.Volts - WARNING *This can kill your CPU, mobo and memory very easily* You need to increase your volts because you've souping up your cpu and memory This is because they draw more power at peak times (CPU LOAD). But this is dangerous for the life of the components and I dont recommend it unless your clued up on this process.

4.CPU cooling - The standard AMD heatsink/fan is good for about +2800 chips. I would recommend that you change your heatsink/fan if your going to run above 200x10.

5.BEST OF LUCK

He's done that already, it's locked.

2.FSB - This is where you can do some some manual changes in performance of the CPU. I found the Bartons to be unstable at 200FSBx11.5+ if you dont up the volts on the memory and cpu. Better to aim for 166x11.5+ or 200x10-10.5.

Lots of Bartons are stable at 2.3GHZ on 1.65V. I've heard of Mobiles that are stable up to 2.4GHz at that voltage.

3.Volts - WARNING *This can kill your CPU, mobo and memory very easily* You need to increase your volts because you've souping up your cpu and memory This is because they draw more power at peak times (CPU LOAD).

Um, no? You usually need to increase the voltage to get the absolute maximum overclock out of the chip, but that's because increasing the voltage increases the signal to noise ratio inside the chip which can allow it to run stable at higher speeds. The operative words there are 'usually' and 'can'- sometimes increasing the voltage beyond a certain point makes no difference. In any case, the fact that they draw more power at higher speeds and higher load is irrelevant.

ajbrun, if you've got the CPU at 200 x 11.5 for 2.3GHZ then that's a very good overclock at stock voltage. You can check it's stable by running the torture test on Prime95; keep an eye on the temperatures while you're doing it though. If it's stable enough for what you want to do though then maybe you don't need to worry.

Rich :¬)

[Zak33]

Rave knows....follow that. Prime 95....case ON, house windows CLOSED, so its as hot as its ever gonna be..

if it survives a night of that...

you've had a result

[ajbrun]

I really don't get it. I've looked on the web page of this prime 95 thing, and still don't understand what it does. Apparently, my computer has to be on for a long time for it to do this thing. But what will it tell me?

Mersenne prime? What is that?

Edit: Ohhh.. Prime numbers! SO.... Whats the point? Why do they need to find new prime numbers?
