Disabling L3 is always slower. In newer games older games synthetic benchmarks you name it. Especially if you have an ALi chipset with 1Mb cache. The performance gain is clear 😀

Every benchmark I've tried has shown that the motherboard cache on my Asus TXP4 lowers memory bandwidth when combined with a K6-3+ CPU (regardless of whether the memory is within the cacheable limit or not). Every benchmark I've tried with my two MVP3 Super 7 motherboards has shown that leaving the motherboard's cache enabled when combined with a K6+ CPU increases performance, though it falls off sharply if you exceed the cacheable memory limitation.

Yes the TPX4 has slow cache vs the K6+ If your motherboard has 5ns or 4ns cache chips then you can adjust timings to be faster.
I actually want to test L3 performance on win XP, I have seen that XP has superior memory bandwidth when testing with Sisoft Sandra.

I can confirm results both ways. It’s try and find out it seems. Though if ss7 it always seems to be faster to leave enabled.
