classic athlon cache mod prob

[gravdigr]

In trying to move the resistors on a classic athlon 750 I accidentally lost one. I know it was dumb but I can't possibly be the only person to have done this. Is there a way to get another resistor? If someone out there has a cooked classic athlon they don't want I'd be willing to buy it for the resistors. PLEEEASE help me.

go to Partsexpress.com, i think you may be able to order the resistors there. Just make sure you get the right ones. :-) They have all kinds of stuff there, check it out. (sorry, I don't know how to post a link. :-))

ok, another question. The resistor I removed was a small box (very small). Can it be replaced by a resistor with leads? Also, any clue on the wattage of this resistor? The one I lost was resistor 101 on the pcb of the processor.

You sure that wasn't the value? SMD resistors commonly have their value coded in a 3 digit number. IE 101, 102, 103, 271, 332, etc.

I know 101 was the resistor # written on the pcb. The resistor itself has 102 written on it. After checking, all the cache adjustment resistors have 102 on them. So you're saying that these resistors are 102 ohm? Can I replace them with a regular 102 ohm resistor with leads?

if you can get a regular resistor soldered to the pcb you can use it. 102 ohm resistors are not common though, but you can buy a pack of 10 100 ohm resistors from Radio Shack and use a multimeter to find a resistor that is as close to 102 as you can get. All resistors have a manufacturing tolerance so even if you can't find one that is exactly 102 ohms you will find one close enough to work

Like I mailed already, the used SMD are 1000ohm, as mentioned in the above link on top of the page. Think you can trust 'the guy' writing that article, it's a german hardware prof. No problem using the normal resistors, but as you can read in the article, they must be able to burn quite some watts. Better ask some electronic pro's about the difference between SMD and 'old fashioned' resistors, as I'm just into chemics.

Maybe the 102 is a malaysian unity for resistance LOL or just a part-nr. If the 102ohm resistor doesn't blow your cpu, it will blow your resistor in no-time, as the resistance is far to low.

Thanks for all the posts. As luck would have it I found a place that has some of these smd resistors. According to the guy I'm getting them from, the cache and multiplier resistors have DIFFERENT values. As I am only modifying the cache (I have a GFD for multiplier) those are the only resistors I am interested in. I also had some training in electronics and from what I can remember (it was a long time ago) resistors are rated by resistance (ohms) and power (wattage). If the resistor I need is a 100 ohm 5W resistor, then any resistor with those values should do (with a very few exceptions). Anyway, I have located some exact replacement resistors but in the process I came up with another question that might be best answered by an engineer if any are listening. With losing one of the resistors one "slot" would be open. Now obvoiusly this would screw up the cache multiplier setting, but what if I disabled the cache in bios and used a program I saw in another post that makes a floppy you boot from that sets the cache? Would powering up with a cache resistor missing damage anything even with the cache disabled? Food for thought.

I am glad I am so uneducated lol.I suggest you buy the newer t-bird and screw all that work.In the end you will still have an outdated system.And for a few hundred dollars{or more lol}You can be cranking around that desk top like a champ

[gravdigr]

fact is, I got this processor, ram, and mobo for free. My dad gave it to me after I upgraded his system. Being the adventurous and curious person that I am I wanted to learn about and overclock this puppie as much as possible. Even though it is outdated hardware it doesn't hurt to learn as much about it as you can. I am making due with what I have and fabricating what I don't (I'm making a watercooling system for this processor).


overclocking is not a destination, but a never ending process

hmm...i have an athlon classic 550 with the caseing off of it...what would be the max multiplayer i could go if i got a GFD?

[gravdigr]

my gfd will go up to 12x, but I wouldn't recomment it with a 550

[gravdigr]

also I guess I should say if you are looking for a GFD I think tom leufkens has some left. Go to http://www.leufkentechnologies.com/ and check out the GFD section. It also has the settings for setting the cache by moving the rersistors (you already know what my experience with this was)
