Windows 7: What's your memory assessment speed?

He's right in saying dual channel won't show a noticable difference to the user. It removes bottlenecks between the CPU and RAM mainly, and places like Wikipedia says in theory it doubles the bandwidth, so like my PC-5400 667MHz at stock speeds should be around 10800MB/s at peak speed in dual channel, but the winSAT mem test just seems to show the single channel bandwidth like 800MHz RAM is PC-6400 so 6400MB/s peak speed, and my RAM is OCed to 750MHz and gets around 6300MB/s, which is right for single channel.

i just cant understand why a system with ddr2 with lower speed and only slightly lower timings can be the same and better than the way i have set up my modules? yet im struggling to hit 8,600?

Possible flaw with winsat itself? Have you tried Everest, Sandra etc to bench it?

I think the problem lies with the path from CPU to RAM. All AMD processors from Athlon 64 to current ones have an integrated memory controller on the CPU die, which accounts for higher bandwidth and lower latency to/from system memory. Although you will see a difference in benchmarks, there is not that much of a difference in application performance by increasing the bandwidth of your main memory.

If another person with an current AMD system posts you will see what I mean.

Have you overclocked your front side bus? Try increasing the frequency of this... your memory bandwidth might go up.

no i haven't, can you do a shot of a bench run with one of them and i will d/l the same prog to compare? i just thought the winsat test would be fairly acurate, even if it wasn't how does it explain ppl that can hit 9,000+ with similar specs but lower speed ddr2 using winsat?

i got it stable at aroud 8630mb/s now.

its not to improve performance, but purely a benchark test, i dont expect to see much or even no difference, its just to find out what the bandwidth transfer rate is and i was shocked once i found out what other ppl are getting with lower specs. so naturally, i wanna figure out why this is, wheather its a bios setting, software, hardware or an o/s issue its good for a reference and for other ppl that wanna experiment. techology these days are just about shock proof, the bios settings are generally easy to follow, red is pushing limits, green is safe, even if you go into the red or if something isnt liking a setting, most mobo's protect your hardware and simply reset to default. and with google a finger click away, you can just about give yourself a degree in engineering. lol

anyways enough dribble.

Firestrider, check my system specs, everything there is up to date apart from my mem timings which im just using intel burn test to finalize. my fsb is at 1801 (the 01 is so it wont drop below the 1800 when fluctuating)

but now that iv'e lapped the q9550 ill prob try again to get to 4ghz when i have the time and patients.

can you edit your post and try to re-attach your pic? it wont work
maybe just use imageshack.com if it still wont work with the sevenforum hosting?

Memory Assessment Speed
Just a curious question; I ran winsat mem a couple of weeks ago and got a 13600+ read. Ran it today and got 15985 read. Only system change was adding a Radeon 6670 Video card. Does memory speed change this much ? What might cause the disparity ?
