hello.

just got a new pc...AMD 64 3200+, ASUS a8n-sli motherboard, and 6800 GS MSI.

HOw do i overclock this computer from 2.0 to 2.5 ghz? im a newbie to the whole overcloking stuf.....any help is appreciated.


ALSO how do i unlock my 6800 GS from 12 pipelines to 16?

Start a little slower. Most 3200s wont go from 2 ghz to 2.5 ghz in one go.
Find in your bios, the section for hyper transport.
Reduce the multiplier from 5 to 4. Then raise the base rate from 200. I would start at 220, to see how that felt. That would give 2.2ghz. Join our folding@home team, for a good solid burn-in, or run something like prime95 or sandra's burn-in prog, for a week or two.
A lot depends on your memory. Are you running DDR400? If so you will have to find the memory settings, and change them to 333. If you have DDR500, dont sweat it.
After a couple or three weeks, raise the HT baae rate again, to say 230, and repeat the burn-in. After a few more weeks, try 235, then 240, then 245, and finally 250.
If your system fails the burn-in at any point, raise the voltage a little. 1.475 works great for me.
Good luck.

wow thanks....a sucessfull overlock...... to 2.2 Ghz and 333 DDR memeory [dunno why i had to do that ....measn ym ram'srunnin slow?]


How long do i wait til i iverlock it further?

and what is folding@hometeam?

Well @2.2 ghz, your memory is running @ 366 speed. If you had left it @ 400, it would have to be DDR440, or at least work @ that speed. To get to 2.5 ghz you would need DDR500, but with your present setting, your ram should squeak through.
To find out about F@H, read the sticky @ the top of the cpu page. It's a great burn-in prog, that will allow you to help save the world, while burning in the pathways on your chip.
It took me almost 3 months before my 3200 was rock stable @ 2.5ghz, and that was running F@H 24/7, so dont rush things too much.

I take it I would have to do the same with regards to my X2 4400+?

ATM its stock, idle 35 celcius, 100% 45-47 celcius. I have a huge Gigabyte heatsink and 120mm fan on it. Suggest OC on air? (i.e. what temp with 100% should I stop?) I read somewhere that the X2 4400+ fails at 65 celcius.

Ok I did the HT to 4x, Increased the FSB to 220.

Now I have an X2 4400+ from 2.2Ghz to 2.4Ghz - running at 47 celcius under 100%, stable for the past 10 minutes. Though at 2.2Ghz it was at the same temperature - I did notice one of my fans is a bit faster now.

Any further advice? Or just wait 24hrs and up the fsb again?

Prime 95 guys, do blended tests (both mem and CPU).
If you go up by 200mhz each time, those should run for AT LEAST 4 hours.
I would be comfortable with 6-8 error free though.

That 3200+ should do pretty nice, assuming its a venice.
Just make sure your HyperTransport doesnt go much over 1000mhz.
+ or - 5 is fine, nothing more.

Set your RAM/HTT to 1:1, this means your RAM speeds will be equivalent to your HTT. So if your HTT is @ 250mhz, so is your RAM. But when you do this, I wouldnt necessarily take your steps in leaps like 200mhz.
Everytime you run a successful test, bump your FSB up 5-8 mhz. Take it slow,
proper overclocking is an all day event, so I hope you have time.

Out of interest, how do I 'find out' or 'determine' my HTT speeds? Its set at 4x, but I find nowhere in my PhoenixBIOS that actually gives a value in Mhz.
January 22, 2006 10:26:09 PM

Generally speaking HTT = FSB.
So look for FSB in your advanced BIOS options...
Then it should give you a number for example : 200

By the way, the HTT you refered to at 4X.
Thats your HyperTransport Multiplier.

See clock frequency is determined by HTT(FSB) x the CPU multiplier
HyperTransport speed is determined by HTT(FSB) X the HT multiplier.

So (stock 3200+ settings) 200x10 = 2000MHZ CPU frequency
200x5 = 1000mhz HyperTransport frequency

Yout HTT is your multiplier times the bus speed you set. Right now, your HTT is @ 4 * 220 or 880.

Only the AGP 6800gs can be unlocked as it is simply a 6800gt with 1 quad disabled. The pci-e version is actually a new chip with only 12 pipes which is why it clocks so nicely. 500 core is nothing special for a 6800gs pci-e.

OK as it primed it nuff and looked stable at 2.2 GHZ i went in the BIOS and decreased the CPU multiplyer to 9.5 ....also i increased the bus to 237....so this time my overclocjk was at 2.25 or 2.26Ghz.

Tried the prime and my temperature went up to like 45. At 2.2 it never crossed 41 evena t load. Is that normal .....i have a Zalman CNPS 7000B HSF.

Also the overclock ...was that fine? ( and ye i did increase my CPU voltage to 1.5v)

My P4c 2600 wont get to 3.25 but will do 3.12 - does that burning in actually work? and if so could it help me reach 3.25/1000?

The first thing to do is POST OVERCLOCKING STUFF IN THE OVERCLOCKING FORUM.... on the forum list, if you keep reading going down, you'll see an OVERCLOCKING SECTION!

Now, close that thread and go there.[/thread closed]
