Athlon 2600+ oc'ing question

post #1 of 9
Thread Starter 
Hello oc'ers,

I was overclocking my 2600+ (Thoroughbred B) the other day and I could only get up to about 174MHz (on 175 Windows wouldn't load).

Taking into consideration my system specs below, I'm guessing its probably my RAM since it is PC2700 (166 Mhz) and I'm pushing the frequency too much. Also when I get to 175 MHz Windows will load for a second then I get the BSOD for a fraction of a second before crashing and I'm pretty sure I caught site of "DIMM" somewhere in there.

I have some PC3200 RAM coming in the mail anyway (2GB) so I'm hoping that will help me a little. Also.. for any of you have oc'ed a 2600 how far did you get? (I know that it doesn't mean mine will oc the same way)

I don't have a very overclocker friendly motherboard either (this was some kind of custom built PC from CompUSA I got a couple of years back). I can only change the CPU freq, voltage and DIMM voltage and I can only adjust the voltages by +1.1% and +2.3% =\\

I know a lot of you guys know overclocking very well so I just wanted to get some feedback from actual people instead of reading a bunch of more oc'ing reviews

Try setting your ram in a divider frocing it to run at pc 2100 speeds. Every computer is different becuase of diferent hard ware so it will be hard to tell you how far exactly you will get.

Hey there, i am currently running mine at a stable 2304MHz with air cooling, i have a Barton XP-M proc so that's why its cooler, but the other difference you're looking at here is the stock FSB.. your's is 266 while the barton runs on 333MHz, non the less i am running mine at 400, a big factor is the memory u use, switch to at lease pc3200 asap and you should see the difference.
Another point is that you are already running your fsb well above stock.. 133(266) vs. 174(348), you may be reaching the limit at your current multiplier (stock in your case since the mobo doesn't let you change it). if you're getting ram then you might want to think about upgrading your mobo too, you have a great proc that is held back by your mobo, look into getting something based on the nforce2 chipset.. you'll get a lot of adjustable settings. Just as an example of what you can get with the proper settings.. my processor is running at the current speed with the vcore at 1.6, my memory is running at stock speed(pc3200) and my vid card is overclocked from 500 core and 600 memory to 550 core and 700 memory. If you have any more questions about oc'ing an xp2600+ feel free to pm me. Good luck.

First off Welcome to the site. what chipset dose your motherboard have.?? If there VIA chipset then it won't overclock very good.

Yea, i run a 2600+ barton, i could load windows at 200fsb, but it wasn't stable at that speed, it runs very stable at 192fsb, thats with pc3200 corsair valueram. it does that at 1.675v. so i went from 166fsb to 192, but when you raise the fsb, make sure to keep your agp/pci speeds close to 66/33 mhz. also, raising your vdimm can help stability. you can raise your vcore as long as your temps are ok.

EDIT: this is with a crappy VIA mobo as well, im at 2144mhz now.

logan- what is your multiplier setting? mine's at 11.5, and have you raised your vDIMM? mine's at 2.8, if you can maybe you'll be able to hit 200 fsb.

music man- keep in mind that thoroughbred b's are good overclockers but you might have to invest in some form of cooling other than air.

shadowdragon, those are the same specs that im at right now, the problem is the mobo, it is a really cheap one. i had it at 197fsb for a while, but it wasn't really stable, it was only running prime95 for like 10mins before it failed. and my OS just corrupted, so i cant work on it really right now....

Hey guys, thanks for the replies and the welcomes.

My mobo does have a VIA chipset =\\ and I know its not good for overclocking (and the multiplier is locked). As you guys mentioned I might get a new motherboard because right now I don't have the money to build a whole new PC but I can probably get a good motherboard to squeeze some more out of my CPU.

A good motherboard will get a good overclock. Abit An7 is one of the best for socket A.
