Just wondering what you are getting in the memory bandwidth and at what efficiency in Sandra's Memory Bandwidth test.

Here is mine..

Can anyone explain why it is so low and has low efficiency?

That is good for your memory ,it is not low ,it is a real good score.

The efficiency is based on the difference between your score and your maximum theoretical bandwidth.

85% at DDR500 is good I think.

I get 92% @ DDR400 but im limited by the VIA chipset, the NF4 boards can score over 6000 @ DDR400.

watever

i get around 200 points less than u.. around 6500 something and 6400 something.. with 81% eff.

i get 5700 and 5660 with an 89% efficiency on my PC3200. youre score is fine ;)

dont forget socket939's are more dependent on latency times instead of pure speed. however, the faster you get, you do overcome the higher latencies.

What timings is that at?? - I forgot to ask.

Also - A64 tweaker is your friend :-)

It allows you to change memory timings at settings on the widows desktop - this is great because you dont have to clear the CMOS if the system locks, just simply re-boot.

I use it to test BIOS settings out for stabilty before changing them in the BIOS itself - saves a lot of jumper changing and hassle!!

TBH im missing my Ballistix, this 2Gb G.Skill set is very good @ DDR400 but its not as flexible and certainly cant be run as tight as the Crucial RAM.

The G.Skill has TCCD chips.

My score @ DDR400 is 5750/5800 depending on whats running in the background (RAM @ 2-3-2-5 1T) 6ns A-Sync + some other tweaks.

Wow weired, 238MHz (2.62GHz) FSB 1:1 3/3/3/5 = 6800MB/sec, 253MHz (2.53GHz) FSB 1:1 3/3/3/5 = 6446MB/sec. using 2.7v

Here are my timings, when I ran my old ballistix (died) at 270Mhz I tweaked the timings a little to stabilize them. With these new pair, I'm only running them at 250 and I haven't messed with the timings at all.

If the Crucial DDR500 is as good as the 400 you should be able to tighten that up somewhat.

Have a play and see what you can nail it own to.

I get about the same as you with my Mushkin DDR500. I get 82% efficiency.

Hmmm... I will give my OCZ's a go later today and see what I get.

Glad to see my trusty old P4 Northy s478 I865 isn't too far away with its 6128/6139 MB/s.

Though I'm sure the a64 lead would be much greater using unbuffered tests.

(BTW, I'm not really comparing since I'm only using 2x512MB)

This thread should be in the Benchmark Section of the Forum, just like 3Dmark05 or 3Dmark06, but anyway...

2x1GB DDR500 folk,
I wanna see if someone can get past the 7000MB/s mark, but with a stable PC 24/7 (flawlessly passing the SuperPI & Memtest stress tests)

raise the internal CPU clock generator, lower the Cas timing, raise the CPU/Ram voltages, actively cool the Ram, watercool the CPU, i don't know, just get a daily stable 7000MB/s score

because in the review @ http://anandtech.com/memory/showdoc.aspx?i=2676&p=15
http://anandtech.com/memory/showdoc.aspx?i=2676&p=16
they were pushing out 7500MB/s with a 2,4Ghz CPU, so ppl like jAkUp with CPU @ 2.75GHz should be getting more MB/s, right ?

when I run my 2 gigs of Patriot 3200 at 1:1 250 FSB I get 7,014/6936 with the timming set at 3-3-3-9-1T.

Well, lowering my Tras to 7 it was at 8 netted me better scores.

Currently I am at 3-4-4-8 and it doesn't seem to budge.

I tried 3-3-3-7, no go.

I am going to try 3-4-4-7 next, but I'm not too sure I will see any increase from it.

Have you tried 3-3-3-9-1T at 250 1:1 ,I get 7014/6936 with those settigs ,how do you save the benchmark and copy and paste it ,I can't find where I can save it.

Just press Print Screen, and than open up paint and paste it in there.
Use imageshack.us to host it

hmm might try that as i am running at 3/3/3/5 so i might try 7 or 8

I can get higher scores at 275x10 but system is not 100% stable,so it doesnt count how much higher it is.The actual score is the first one ^^(250x11)
