after a slightly hostile/heated "discussion" in someone elses thread i decided to make my own so not to spoil the other thread anymore........
anyway after "upgrading" from an A64 3200/2000/1mb skt 754 to a A64 3200/2000/512kb skt 939 i found quiet a large performance drop, which at first (and i still do slightly put down to loosing 512kb cache). looking around reviews people posted or others ive seen i noticed that 1mb 754 vs 512kb 939 is around 50/50 wins for both IE 3500 vs 3400 yet right now most the things ive tested have clearly show a 90-100% win streak for my old 1mb system. Something clearly must be wrong......
quote from the "other post"
so from that post i see the main differences are, the timings
210 2-2-2-6 SC vs 220 2-3-3-6 DC (although 210 2-2-2-6 does no favors)
and AGP/PCI lock?
btw i can also run at 8.5x260 2.5-4-4-8 with my single 512mb crucial, but thats single channel and will hurt (as i said the other crucial chip i had died today) so instead i got 2x256 corsair, which can run slightly tighter timings at under 230, but stops working after about 247
2200mhz seems the top for 1.47volts, and 2400 is "benchable" @ 1.6volts but thats hardcore for 90nm so i wont be doing too much of that.....

I could suggest things like are mem timings the same? same board? Same OS and same drivers? But I'm sure you thought of these things.
i cant run it in the same board can i, different pins
look back anyway, i edited after you quoted.
in truth i should be expecting close to the exact same performance between the two right? so theres got to be something i missed.
Same parts: Ati 9700pro, Dlink 538xt, SB audigy, maxtor 160gig sata hdd, 431watt psu.
2 systems:
Skt 754:
A64 3200/2000/1mb
Asus K8V deluxe
512mb PC3200 2-2-2-6
Overclocked to 2100mhz, ram 210mhz, HTT bus@ 840, PCI/AGP 35/70 (AH thats one thing thats changed, AGP overclocking!? much difference?).
Skt 939
A64 3200/2000/512kb
Asus A8V rev2 deluxe
1gig PC3200 2-2-2-6 (err now back to 512 since the crucial died! )
Right now its only stable at 2200ish, Ram 220, 2-3-3-6 (another difference), HTT is 1100mhz or 880, PCI/AGP locked at 33/66 (i think)

Ok certainly i did'nt meant to be hostile to you. And look, i can't run those tests WITH MY OWN EYES (just using your emphasis on this) because i lack the money in buying parts just for testing
Also, your very private Testbed and your comparsion of the two sockets is not what i call clean. I could even post another six benchmarks of independent web sites prooving my point, even others do post other results, yet you only trust your eyes without doubting that you are doing something wrong.
Anyway, i see your results and indeed, your s939 rig is performing weak compared to the 754, but did you notice that the 939 is actually faster than your 754 by a small margin? Second, did you notice that you are largely peaking out into the same range because you are not hold back by cpu performance but by your 9700 gpu?
You can even comapare to an s754 2800+ at stock with identical configuration and i bet it won't be behind by a large score.
What you can do, if really something is wrong: Check htt multiplier on your s939, do you run 1t rate? Do you ûse correct ram timings or some horrible settings? Well i doubt it, i bet everything is correct with your 939 rig.
What you can do to test further:
Use SuperPi or switch to 640x480res in 3dmark01 so that you are not gpu bound, or even use 3dmark05 as it has a dedicated cpu performance bench and report back with your results (if you want to).
started well, then got hostile near the end
i will look into it, just a bit pissed this ram died
