So for those of you who say that Semprons are worthless, old, etc. - here's a new one for you. The Sempron 3300+ I purchased was a retail box, and it is a Rev. E6 x86-64 compatible processor. Granted, it only has 128K of cache, but oh well. This overclock was achieved using less than the best of parts in a less than desirable SFF environment. Here are the relevant hardware specs:
AMD Sempron 3300+ 2GHz 128K L2 x86-64 compatible retail boxed processor
Jetway A200GDMS mATX s754 motherboard (based on RS480 NB and Uli M1573 SB) - Rev A02 BIOS
Corsair Value 2x512MB DDR400 CAS 2.5 DC kit
Gigabyte 6600GT PCI-E Retail
Antec TruePower 430W modded with Cooler Master Rifle-bearing 80mm LED fan
This was all in a Chenming 118 mATX chassis with Antec 120mm fan, Zalman 7000 AlCu for CPU, and Zalman VF700 AlCu for GPU.
Stability was tested using Prime and MemTest86+.
So far, at 1.475V Vcore and 2.65V Vdimm, I have reached 2500MHz CPU and 433MHz RAM perfectly stable. I am currently testing higher processor frequencies, but 2.67GHz seems to be about the maximum for this setup. To be safe I stuck with my conservative 2.5GHz. As for the GPU, I used the Coolbits 2.0 registry tweak to auto-detect "optimal frequencies" for my 6600GT and came back with 585/1170 from a default of 500/1000. No artifacts during extensive 3D Mark '03 testing or gaming (CSS and Joint Ops).
Now for the benchies:
SuperPI 38s 1M Calc
3D Mark '03 score of 9390
This is compared to a stock time of 46s and stock 3D Mark '03 score of 8032.
Preliminary conclusion: budget processor/ram/gaming setup doesn't have to mean poor OC ability. I built the SFF for $700 shipped, this included the cost of processor, RAM, motherboard, chassis, cooling, hard drive, and a few misc. items. Optical drive, floppy, and PSU came from my previous system. This type of system is a definite contender for the college gamer who needs portability + power.
Edit: BTW, the voltage reading on the proc is off no matter what because CPU-Z cannot read the value from the correct location (can you please get some good support please, Jetway?) The voltage should be 1.48V +- .02V
