Maybe this can help so you guys don't have to go through that whole thread. Keep in mind that these differences make zero real-world difference...it's just benchmarking speeds we're talking about. Anyway, here's a copy of my post from the abit thread:
Hi folks! So I decided to spend a little of my Sunday playing with v.14beta05. I'm deleting the previous testing post again to edit it for the new results and post it here. Straight to the nitty-gritty:
The overclock used for all testing is as follows:
10x 300FSB (3.0GHz) @ 1.365Vcore
1:1.5 CPU : DRAM ratio (450MHz, or DDR2-900) with 5-5-4-15-2T timings @ 2.10Vdimm
I ran five SuperPi 1M tests and a single test each of SuperPi 32M and WinRar's benchmark (time to crunch 100M plus speed). Single tests were simply due to time constraints. Apologies for the formatting; the forum didn't like spaces.
SuperPi 1M test results:
BIOS------------1.--------2.--------3.---------4.--------5.--------Avg.
v.12----------19.125--19.093---19.078---19.078---19.078---19.088
v.13beta-----19.140--19.079---19.079---19.094---19.094---19.089
v.14beta04--19.172--19.141---19.140---19.157---19.140---19.146
v.14beta05--19.078--19.094---19.156---19.078---19.094---19.089
*Averages were obtained by throwing out the highest & lowest time, then averaging the remaining three times.
SuperPi 32M test results:
v.12-----------17min, 26.344sec
v.13beta -----17min, 26.594sec
V.14beta04 --17min, 21.391sec
v.14beta05 --17min, 29.859sec
WinRar benchmark:
--------Time to reach 100M------Speed
v.12-----------2:35--------------642KB/s
v.13beta------2:35--------------643KB/s
v.14beta04---2:36--------------641KB/s
v.14beta05---2.36--------------641KB/s
So, at least from my testing, v.13beta is VERY close in speed to v.12 and v.14beta04 is slightly slower than the other two. v.14beta05 seems to be on par with v.12 & v.13beta.
If I had time to run more 32M tests, the obvious anomaly may work itself out, but I don't.
In any case, they're too close to see any real world difference, but in case anyone was curious, this is how each of them perform.
The icing on the cake is that unlike any of the previous BIOS revisions, I was actually able to get 3.5GHz, boot it into Windows, stress it for a couple minutes (I'm only on air remember) and run SuperPi. It took 1.565Vcore set (1.52 after Vdroop), but I couldn't even get 3.5GHz to boot into windows before; the most I could get out of that Vcore (my personal limit) was 3.45GHz. Needless to say I'm a very happy camper, but oh to be able to afford water! (
Here's a thread w/ SSs on that OC if anyone's interested.)
There you have it....hope it helps!
