Hi I am experimenting with an Athlon 2400+, learning to overclock with it. I was originally overclocking by increasing the FSB in the BIOS, but I dont like the idea of frying my memory or expansion cards. I now know how to change the jumper settings on my mobo to get my multiplier from 15 to 16, but can anyone tell me if i need to unlock the L1 bridge on my Athlon 2400+ (Thoroughbred B) before changing the jumper settings will have any effect on my multiplier?

what motherboard? my mind reader isn't working today Abit NF7-s 2500+ @ 3200+ 512 Corsair XMS PC3200 128 meg Radeon 9800 Pro 36 GIG WD Raptor SATA 3+ Mbps cable connection

by the way...your info says 2500+ and in your post you stated 2400+...which is it? if it's a new xp, you can not unlock the multiplier....if it's a decent board, you can lock the agp/pci bus to 66/33 and overclock to your hearts content without overclocking the busses Abit NF7-s 2500+ @ 3200+ 512 Corsair XMS PC3200 128 meg Radeon 9800 Pro 36 GIG WD Raptor SATA 3+ Mbps cable connection

Raising the multiplier overclocks the CPU only...you'll gain very little (if any) performance by going that route. FSB is where you'll see the performance gains. You'll just have to learn the limits regarding the PCI/AGP speed increases...& that varies from board to board, depending on what options are available in the BIOS. A good rule is not to let the PCI bus go beyond 38mhz. There's no need to unlock your XP...it should be already unlocked. If it's not, it's one of the newer models & can't be unlocked. Most people lower the multiplier so that they can raise the FSB even higher...that way, they can keep the overall CPU clock speed reasonable, but gain even more performance. As an example...here are some various settings for a 2000mhz CPU, but still staying clocked at 2000mhz: 20 x 100 (slowest) 15 x 133 12 x 166 10 x 200 (fastest)

To Third4point6LX97 The reason my info says 2500+ and my post says 2400+ is because i signed up for this forum on my better computer (2500+) and i am trying to overclock my not so good one (2400+) because it wont matter so much if i make a mistake. My board is an Asrock K7VM4. How do i lock the agp and pci buses then (if i can on my board). To jam What do you mean by 'one of the newer models'. Do you mean it was built recently, or do you mean it is a modern processor type? If it is the first one, how recently is new? B T F I C O H L N O B E Y- G W

here's the url to your manual http://www.asrock.com/Drivers/Manual/K7VM4_UM_v11.pdf page 6, section 5 says that it is not recommended for overclocking..when you change FSB, that in turn changes the frequency of the pci,agp and memory clocks in proportion you got 3 FSB jumper settings of 200, 266 and 333 as shown on page 12... your multi settings are contolled by jumpers also and that diagram is on page 13 page 22 shows you that you can change your memory and cpu clocks, but since you do not have an agp/pci bus lock...this makes for a very unfriendly overclocking board...in other words, you can go a little above stock on the FSB, but too much can result in hard drive data corruption and fry your pci cards,sound and video....there's too much at risk...i suggest to leave it as is or get a better mobo Abit NF7-s 2500+ @ 3200+ 512 Corsair XMS PC3200 128 meg Radeon 9800 Pro 36 GIG WD Raptor SATA 3+ Mbps cable connection

By "one of the newer models", I meant the newer model 2400+. I'm sure someone will correct me on this if I'm wrong, but I believe AMD has begun locking ALL it's XP CPUs now, not just those with the Barton core. I think the new XP core is the Thorton, which is basically a Barton with 1/2 the L2 cache http://www.xbitlabs.com/news/cpu/display/20030425073021.html
