Preface...I am brand new to this forum, so if I step in it, please forgive my mess. Also fairly new to overclocking.
I have read some of the overviews on overclocking, but I am looking for some answers specific to my processor. I am running a SDA2500DUT3D on an EPOX
EP-8RDA3+PRO mobo. As we speak, I have it clocked at 2310 mhz (220 x 10.5, which is locked) with the vcore set at 1.7v. Temp is 47-48c at full load. So far, my Kingston PC3200 ddr is living ok at 440mhz (220 x 2) at standard 2.7v.
Don't really want to get radical here, think I am pushing pretty far already.

What is the maximum vcore you folks have experience using with this cpu without shortening it's life appreciably? I understand this depends a lot on temp control, but how high a vcore is still safe?

How high has anybody else had luck clocking this processor (just curious).

Also, when I bought this processor (2 weeks ago), the package said it was a thoroughbred core (date code 0508). I read elsewhere on this site that "all semprons are bartons". What's the real scoop?

Also been reading all over the 'net about unlocking the multiplier on this chip to overclock, changing L5 jumpers to make it a 'mobile' cpu to unlock the multiplier, and some insisting it is 'superlocked', and you can't get around it noway-nohow. Also read about some software multiplier changing once you have a 'mobile' cpu, but apparently they won't work with the nvidia nforce2 which is on this mobo. Any input on that whole 9 yards?

Hope this isn't all too much for one post, just looking for some friendly input from any interested members.

Thanx, harvshark.

Hi sharky

I myself am new to the forums and have been doing reading just as you have. When it comes to the cpu being locked, I have learned that now cpu is ever truley locked. I have an XP 2400 which is supposedly super locked. My multiplers are locked so I cant adjust them through s/w oc'ing.

2 Programs that enable s/w oc'ing are Crystal CPUID and CPUMSR. I myself have an NForce2 board. I can oc with the FSB not a problem. But for some reason, I still cannot change the multiplier through the software.

What I did find was that the wire or pin mode works to an extent on my CPU. When I unlocked the multipler through this method, the multiplier defaulted to 7 and my cpu ran at ruffly 900Mhz. Even though it was technically unlocked, I still could not change the multiplier though the s/w. Soo, what I am in the process of doing is, with the pin mod, I will be setting the multiplier manually to somewhere b/w 10-12 and upping the fsb to about 200 if I can and I will go from there. Although I dont have the luxury of changing the multiplier through bios or on the fly, I can manually set it to a fixed multiplier and go from there. Although it may be a hassle to redo the mod everytime I want to change a multiplier, its still a start...better then no modding and no oc'ing.

I also find the wire/pin mod to be safer in a sense that..its totally reversable and there is no need for any physical modding with the bridges on the cpu.

In regards to the Sempron...they are all 333fsb so that must be a barton. I have never seen a tbred at 333fsb. What you have is very interesting

the most I have ever seen on Vcore was my 2000+ at 1.95v.... but I can't prove it because it didn't get to windows.... I suggest to just keep it below 1.75... and temps below 55°C.
Always use prime-95 to test Overclocking stability
CPU-Z is also a good tool to show your true overclock
Here is a page that has some of the most popular Overclocking tools: http://www.overclock.net/downloads/

My Processor isn't a mobile either and I have a unlocked multi. I guess it's just the luck of the draw. Don't feel bad, Around 2.2-2.4 ghz is plenty power for an amd.

Dunno...got it from tigerdirect about 2 weeks ago after a 1 week backorder. They now don't show any socket A processors available for sale (pity the poor dinosaur). I upped the vcor from 1.7 to 1.8 volts last night ('cause I'd had a few and the thing locked). Holding at 53c at full load....yikes, is that too high??

Not quite true,
The Thoroughbred Semprons are defiantly not Bartons..., Just Thoroughbreds with higher FSB and lower multiplier.
The Thorntons tho are an entirely other thing, they are identical to the bartons, they were just modded to lock 256-bit of L2 cache.
