Unlocked L3 cache => RAM becomes slower?

post #1 of 5
Thread Starter 
First of all, is Maxxmem2 a reliable benchmark program?

As I mentioned in another thread, I unlocked the L3 cache on an Athlon II X3 Rana, and have been running benchmarks to see if everything is stable.

This is what I get with a locked CPU:



And this is what I get with unlocked L3:



Does that look right?

Cinebench scores, on the other hand, improve after unlocking L3 (2.81pts with L3 vs 2.69pts without L3).

unlocked = unstable

Benchmarks and stress tests are not indicative of anything. Do it where there is no question that is stability.

As far as the latency goes over 60ns is consistent with Phenom II benches; the explenation is rather simple, now when the CPU cores need some data they seach it in L1, L2, now also in L3 and then RAM- there is one more hop until the cores go to the main memory. The drop in bandwidth may come be caused by the same thing.

You could always try overclocking the Northbridge? I'm getting about 11.10GB/S in memory score on MaxxMEM and my latency is about 48.5

^ This. Overclock the CPU-NB, this is totally underestimated my some overclockers.
