Using all 4 memory slots on a NF4 motherboard?

[Zim]

Having recently filled the two remaining memory slots on my MSI K8N Neo4 motherboard, I am no longer able to run my memory at 1T. This problem is well known but I was wondering if this is a stated limitation of the NF4 chipset, or whether any amount of tweaking can overcome it?

Thx

The RAM controller is on the CPU not the chipset, thus, this is anything but a chipset issue. Next question 😉

Well, the question is still if any amount of tweaking can overcome it?

No. And, really, the difference in actual RL performance is negligible. The benefits of running 2GB will far outweigh the move to 2T. Do the benchmarks and you'll see.

It depends on the benchmark. Memory bandwidth benchmarks show a 20% reduction in performance going from 1T to 2T.

2t has a realworld difference on average of 3% in most cases, in memory intensive apps it can be a much as 5% in the real world. synthetic bench's don't count 🙂

Sure, memory benchmarks do show a difference - but that difference is largely irrelevant to actual applications and games.

Besides, it's not a controller limitation or somesuch, but the simple electrical reality that adding load onto a bussed signal degrades signal quality, which in turn lowers the feasible signalling rate.
