Hi all.

Well last night I tried OC for the first time. no real reason, just seemed fun. Have a AMD 1900 XP and bumped the (actually dont know the name - either FSB or something else) to 136 x 12 and the CPU temp jumped from 43 to 48-50C. Is this a normal temp increase? I really would like to get up to 1670 (139 x 12) to equal a 2000 XP, but not if the temp is going to spike up like this...or am I doning something wrong?

Also anyone here ever use EasyTune III? Came with my Gigabyte, and seems real nice, but everytime I try to OC the darn thing it resets itself after rebooting (and yes I have the option to reboot OC selected) Thanks for any help.

You are rasing the FSB,

That isn't a normal temp increase, what kind of cooling do you have?

You will be able to get to 139x12 easy I would say.

You may just need to install some better cooling.

Well, those temps don't sound so bad to me. I'd take it on up some more. My 2000+ jumps from mid 40's to low 50's, even 54 under full load and is quite stable at that temp.

50C is still fine, but I was just saying in sich a small increase in the BUS he got a large temp increase.

bdmst16 tell me your Room Temp .. taht is so important..
example.. summer day like 90F+ my CPu can get up to 65C..
like right now my room temp is 72C and my Cpu 1700xp run 45C..

[bdmst16]

Room temp...hmmm, well it would probably be in the mid-70F's (no clue in C 20ish??) Speedfan is reporting 34C for system and 45C for chip at default speed (1900@1605, 133 x 12). I have a Coolmaster HC-003 on the chip and three case fans (one front, two rear). Its kinda close to my window air conditioner unit, so that corner of the room should be cooler.... Just seems rahter high with my cooling system. Thanks for the help all.

bdmst16 ,


are you OCing with speed fan?

[bdmst16]

Hmmmm thats a new one. How the heck do you do that? The HC-003 is running around 7800-8400rpms, not sure how to increase that.

LoL read this thread subject again :D Newbie Overclocker :D so how the heck he know how to oc with SpeedFan. :x

[crusious31]

oh lol i thought i saw somewhere that you could OC or increase the FSB with speedfan. well i guess i was wrong.

do do you guys use a program to OC :rolleyes:

im kinda clueless

[bdmst16]

I use two methods.

1st. I agjusted the FSB in the BIOS, but I don't think that it will check to see if it is an acceptable speed (ex, 200 FSB)

2nd. EasyTune III supplied with my mainboard (Gigabyte). Allows the user to manually adjust FSB and then slowly increases the FSB until the system becomes unstable. *BUT* I couldnt get the settings to remain after rebooting.

Im really new to this aswell, try to find some tutorials on overclocking here, or just seach past posts.

I cut and pasted this from one of my old 3dmark guides. Though unplugging PCI devices in your case is not necessary. Disconnecting devices is necessary sometimes when running high FSB(usually 190+) when PCI bus speeds are being OCed to high.

OC'ing tips:
1. Unplug all unneccasary devices such as sound cards, cd-roms, NICS floppy drives. PCI devices don't really favor OC'ing because of bus speeds.

2. Make sure you have adequate cooling. If your CPU's already running at 40 degrees celsius, you won't get to far. I had to drop my CPU temp to around 0 degrees celsius for major OC'ing. Yet with stock cooling I can still bring my 1.33 amd to 1.53 ghz 24/7.

3. Go up in small increments. No more then 5 mhz for core or memory per step for VGA oc'ing. Make sure you have it set so that if you have a failed OC, your default settings will load up after boot or you'll have to clear CMOS and reset BIOS settings.

4. With overclocking FSB, go in 1 or 2 mhz increases. OC'ing ability will depend alot on your RAM manufacturer and quality. With OC'ing CPU mhz only go up .5x on the jumpers. For example, 10x133 equals 1.33 ghz or 1333 mhz. So a 10.5x133 equals 1.39 ghz or 1396mhz. The jumpers are either on the mobo itself or in BIOS. You can use programs in Windows to also change CPU settings though I would stick with the other 2 options. Only change the jumpers while the computer is off if the jumpers are on the MOBO. You can get to the BIOS screen while holding the delete key at boot(I know its the delete key for most MOBO's).

5. You can also check the stepping of your CPU by looking at the surface of the CPU chip. Sites on the web compare different CPU steppings with overclockability. Though that would mean having to remove your HSF which can sometimes be a pain.
