I was sure we had a BANDWIDTH thread here at XS but it appears I am wrong.
Perhaps it's time to start one?
I think it'd be good to be able to compare all kinds of memory and their related bandwidths at different speeds.
People can use this thread as a reference as to how well their RAM is performing against other brands/speeds and across platforms.
I'll start the show with mine.
(CPU)AM2 X2-3600 @ 3000mhz (300x10) (MEMORY) A-DATA DDR2-800 @ 750mhz (4,4,4,12,18,2t)
Hey, a fellow LFS player :)
We also both have X2's at 3Ghz ;) We should start an AM² X2 LFS clan :up: :ROTF:Quote:

I will start playing it agin, once I move in 4 weeks, so if ping aint too bad, we could have a race together or two ;)
Sorry for offtopic :P

2. 3500+@3GHz 65nm Lima core, same memory as above. Sorry for not having Sanda screen but I was getting 7660MB/s.

Clearly big advantage for X2 CPU version. BTW latency measured by Everest has not changed at all between those two processors (in contrary to S939 SC and DC CPUs where SC was faster in memory access and bandwidth) so it looks like single core 65nm has cross bar and memory controller from dual core version. In other words Lima looks to be capped Brisbane.

Cool, cheers for submitting guys :)
I think we should get a TOP LIST started in an attempt to lure out some of these BIG-HITTERS. I'm sure someone on XS can show us some EXTREME BANDWIDTH.
Where are the C2D guys anyway, they usually can't wait to show up the AMD rigs :p:
Not to mention the DDR3 guys with their $500 dollar memory.....show us bandwidth :)
There is another thread here too:

Feel free to post in that one :)
this is my proudest memory bandwidth score:
the was with Ocz PC3200 Rev 2 (samsung TCCD) DDR Ram :yepp:
I will post up some scores with My AM2 4800+ whenever I put the system back together..
I'd run it but I have crappy RAM :p:
my wintec ampx pc6400 was great, it did 550mhz 5-5-5-15 2.2vQuote:

I'd like to know what people are getting for L1, L2 and Memory Bandwidth MB/s in Memtest86+ 1.70

I really need to boost my bandwith, nice results around here :up:
With my new cpu: 11863 mb/s

Here there is a shot with DDR3 1800 Super Talent, and Intel achitecture (AMD architecture is more efficient because of memory controller integrated in cpu core):
http://www.atris.it/Forum/photoplog/...rf_level_6.jpg
I think it could be very useful to specify the version to be used for sandra and everest because results from different versions could be not comparable.
everything in ss below
sandra bandwith: 10278 MBps
Watercooled 6850ES and Cellshock 9200 !

that's better than what i run with the rig in the sig, almost in the same ballpark

decided to try out sandra 2008 and post results, had to use x32bit install since x64 gives memory overrun errors
Got a 6000+ to play with.
2GB kit (OCZ-DDR2-900 SOE)
http://home.comcast.net/~themysticwi...1075-55515.JPG
Pushed my memory a bit farther (537.5 mhz @ 5-5-5-15) requires 2.5v though.
Before I had it at 430 @ 4-4-4-12.
Not bad for Corsair CM2X1024-6400C4 v 2.1.
But I do think I need some better memory now that I got this new mobo.
Very interesting score:Quote:

Yes mate.....I wondered about this also.Quote:

These dimms even run to 491mhz with 4,4,4,10,2t but give almost exactly the same results as 5,5,5,13,2t with literally only 200MB/s increase on read.
Maybe I've missed a setting somewhere :confused: Or perhaps ADATA just make better dimms than OCZ :down:
I think it was not your fault, there is something strange with everest or maybe it is something related to chipset+cpu achitecture because also L1 and L2 bandwidth are really low. :confused:Quote:

I can't seem to find any older versions of everest......so I grabbed Sandra.....looks about the same here. :confused:
Thanks a lot for the test, but with sandra we are not able to understand if memory write bandwidth is greater than memory read bandwidth.
Memory read is the same! (edit: it is very low compared to other results in the same thread with the same architecture)
my write bandwidth can exceed in Everest...
just see my earlier post. also, somethign of interest for you Soldner...
http://img209.imageshack.us/img209/6011/image10gi1.jpg
read bandwith with and without C+Q running. and the bigger score is C+Q ON!
Hmmm that is a puzzler.
I tried with C&Q ON and OFF with 4,4,4,12,2t......but get the same each time. My COPY even exceeds my READ now....this is crazy..lol
mofo, whats your asynch lat? and other mem timings?
omg im blind rofl...
smth is really weird there. can you use everest 4.0 insted of 4.1beta?
well i have a possible answer for the copy bandwidth -
soldner, try using rightmark cpu utility to lock your multi at.... god this is confusing... lock at 6X (should give a mem speed of the same as current using - check with whatever app you like) then re-run. does the copy mb/s become even more out of line? (i expect all to drop by >1/2, but copy to drop less so) if so mine does the same and it seems to be an oddity of the amd mem controler - raw thruput is heavily reliant on mhz, but copying data is more reliant on memory. eg, faster memory/slower cpu = copy out performs read/write. faster cpu than ram, and read/write perform better. - doing this for me takes me from a copy of ~6700 to ~4800 read drops from ~8K to ~4K. (i start with slower ram vs core speed while you have much faster ram, not much more core speed)
also, new and improved iffy-marks tm incomming...
no C+Q = 7790 / 7894 / 6767
http://img441.imageshack.us/img441/4...titled1vl7.jpg
classic ddr @ 258mhz 3-3-3-8 1T v close to DDR2 @ 459 4-4-4-12 2T.... not likely
- bahavior exactly the same under V4.00
That is very strange indeed. I'll try as you suggest with rightmark to see if you're right. I'm updating the NUC thread offline just now so it may take me a while to edit this.
florent! what ram ar u using??? and at what voltage???:up:Quote:

this is the best i can do with this memory... can go to 512mhz cl5, but 492mhz Cl4 gives better result.
pretty good for cheap DDR2 333mhz :p:

I used to have some OCZ PC4800 Platimum Elite editions that would run at 2-2-2-2 but unfortunately I never had anything better then a XP2500+ to run them with. Wish I had kep them for nastalgia purposes. God those were some awsome stix. About the only chips better, ever, were the BH5 chips.
not good :shrug:

Not BAD for 408MHz, 5-5-5-15 timings.
I can't get board to run my HZs at the 520MHz @ 4-4-4-12 that my DS3 used to :( It crashes on post. When I manage it, I'll re-do it, should be much higher that it was on the DS3..
