Why have I got a crap Memory Bandwith score? 1055T

post #1 of 7
Thread Starter 
Northbridge @ 3000MHz
RAM @ 1600MHz CL6-8-7-23-27 1T
CPU-NB 1.37
DRAM: 1.65V

The software "MaxxMEM" show's that my memory bandwith total score is around 10.40-10.60GB/s

And looking at this http://benchmarkreviews.com/index.ph...1&limitstart=1

Towards the bottom of the webpage, I'm supposed to be getting alot more bandwith

•Up to 21GB/sec dual channel memory bandwidth

That actually seems quite good for a Phenom II. The SB's would probably only get about twice that. I don't think it's even remotely possible for a Phenom II to get 22GB/s.

Slightly better than what I get. Memory is bone stock.

@tehmaggot

Now I'm really confused why you have soo much VCore pumping into your CPU @ 3.9GHz?

I can get 4.0GHz @ 1.47V I think you will get around the same score as me if you got your Northbridge upto 3000MHz

My CPU is an absolutely god-awful OCer If I drop it too much lower, it isn't stable. Anywho, I'm going to do a run at 3Ghz NB (not sure why it's at 2.7 to be honest) and 1T.

Edit:
Here's the result at 3Ghz NB and 1T command rate:

Not since the S754 days has actual bandwidth really come close to theoretical bandwidth.

Also, MaxxMem isn't threaded well enough to really push the memory to the utmost. Then again, neither are most programs.

Anyway, nothing seems wrong with your score.
