We'll do it here. It would only go to 132 because there is a jumper somewhere on the motherboard. Do you have the motherboard manual? Skip

Yea right after I posted I looked in the manual, it says for 12.5 set switch 1 and 2 off and 3,4,5,6 on so i did that, went into the BIOS and still i can only goto 132. Before all of them were off and the manual says that sets it to auto

They make several KT600 boards but look between the agp slot and battery and you should find a jumper. Remove that jumper and the board should autodetect your 2800+. Do this with the machine off. Skip

It was a blue switch that said on or off i switched it off and i set the multiplier to 12.5 earlier and now it made the default 166....so lets say I wanted to overclock would i increase the multiplier or would i go into the bios and change the 166 to something higher...and if i did overclock how much could i increase it without overheating? I also want to thank you...it could have taken me 30min-hour to figure this out because i would eventually look through the manual, at least i will know a lot more when i build my next computer..

OK, set the switches back to all off. Multiplier is locked on your cpu and the switches will have no effect. We need to get the fsb into auto by turning SW1 off. When SW1 is on it sets the fsb to 100, which is where you are now. Unsure if it's a switch or jumper but the same thing I sopke of above. Skip

I have another question since we are talking about it....what should be my average CPU temp, right now 41 and 42 when should i be concerned..? Another question, lol....how do you know that a 2800 is suppose to run at 12.5? for example if i got a 3200 how would i know what to set it to? does it say somewhere in the manual or what..?

0

SW1 is off...thats the switch i had to set to off to make it 166 because when i set my multiplier to 12.5 it had no effect and thats when i turned SW1 off and it made 166 my default

To begin overclocking, let that thing run at default speeds for a few days and check temperatures, stability and so forth. While that is happening, read your manual from front to back then read it again. This will get you out of trouble if anything goes wrong when you try to overclock. Make a complete list of exact motherboard, processor, memory, and power supply you're using and do some research online to see what the limitations are for your hardware. This forum has a how to overclock question about 1 out of every 4 or 5 posts for you to read and make some notes. Good time to start a notebook now to write your overclocking efforts down. Ya gotta read this stuff and understand it. If you'd got to page 10 or so in your manual, one of this would have been necessary. Good luck and let us know how it's working. Skip

1. 42°C is great. 2. I looked it up. 3. With all the multi switches set to off (auto) and SW1 set to off, the motherboard would automatically detect a 3200+. 4. Yes, it's in the manual. In particular, you need to read and reread the section about setting up your bios before you start overclocking. Skip

Ok, thanks...there are still two questions I wanted you to answer please :) What is the average CPU temp so i will know if its getting too high....and how did you know that a AMD 2800+ should be set to a 12.5 multiplier, how would i know what a AMD 3200+ should be set to?

oops didnt see your last post, sorry

Yeah, we're stepping all over each other here. I use a site with updated processors list: http://www.rnet2.dyns.net/artikkelit/prosessorit.xls That downloads an excel file that's updated all the time. It's also on the downloads page of my website as is excel reader if you don't use microsoft office. On the spreadsheet, using your 2800+ as an example it shows the Mhz (2083) and fsb Mhz (333). We have to calculate the multi by first knowing the 333 is really 166. Divide anything under the fsb column by 2. Now 2083/166=12.5. My 2400+ is listed as 2000Mhz and 266; so, 2000/133=15. Remember the fsb Mhz is divided by two on an AMD XP processor...it's what is called double pumped. Clear as mud? Now, a 3200+ would be 2333Mhz/166=14 for an off the shelf 3200+. Or, the other 3200+ barton would run at 2200Mhz/200=11. When you refer to this spreadsheet you will commonly see an XPwhatever+ listed more than once. That's because of different cores like Thunderbird, Palomino, ThoroughbredA, ThoroughbredB, Thorton, Barton and so forth. They may or may not run at different fsb speeds. If you're looking to overclock your 2800+ to a 3200+, you'll likely hit it somewhere around 185 to 190Mhz. Depending on your motherboard and memory, you may be able to go higher. Each rig is different and you can find out the fastest stable setting by going up a little at a time. Skip

If I mess around with it going up a little each time how will I know when to stop, if i monitor the temp each time I adjust it what temp should be a warning sign that i have increased it too much?

0

Usually, the first sign is instability, like it'll crash playing a game. If you go too far, the machine just won't boot. I test with toast.exe for 10 to 15 minutes. Toast won't hurt anything...your rig just stops responding after a few minutes. http://www.upoa.de/downloads/toast.exe Download toast and something like MBM5 to watch your temps and see what's cookin' at the default settings first. If you're at 42°C at idle, it's likely to go up 10-12° running toast. Write the temps down and do the same test as you increase the fsb. You'll find the stopping point. Don't get in a hurry. It's a pretty simple process but, take your time and write everything down. Skip

0

To answer your other question, I'd try to keep cpu temp under 50°. Generally, I can expect small problems somewhere around 65°C. Just depends on the machine. AMD says 90°C is max. Skip

0

what exactly am i using toast for?

0

toast stresses your cpu. If you have a problem with stability or excessive heat, toast will not continue to run. Gives you an idea of when you've gone too far. If toast will run for 10' you can bet all your programs will run stably. Skip

Skip, Wow...23 responses? I saw this last post last nite & figured it was settled with your 1st response...lol Liquid9, I recommend you NOT overclocking your CPU just yet. Everything you asked was written in your manual...you need to take the time to read it & reread it until you fully understand it. Just run at the default speed for a couple of days...in the meantime, take the time to learn about overclocking...how it's done, what the risks are, how to recover if your system becomes unbootable, etc. There's a lot to learn. Scroll down thru this forum & read thru some of the posts. Go to Google & use a search term like "overclock Gigabyte KT600" & see what you come up with. Here's a few sites to get you going: http://www.overclockersclub.com/overclockingfaq.php http://www.hardcoreware.net/reviews/review-171-1.htm http://www.overclockers.co.nz/ocnz/review.php?id=03boardkt600000gigabytekt6013940105 http://www.overclock.co.uk/customer/product.php?productid=16908&cat=427 http://www.tweaktown.com/document.php?dType=review&dId=576 If you wanna know the proper clock speed for the various Athlon XP CPUs, go directly to the source: http://139.95.253.213/SRVS/CGI-BIN/WEBCGI.EXE/,/?St=35,E=0000000000159936366,K=7066,Sxi=14,Case=obj(1224)
