m1530 memory transfer rates?

anyone know where i can get the specs on the memory transfer rates for 3 gigs of memory installed on this thing?

the reason I ask is because I tested my readyboost SD chip's transfer rate and its about 8mb per second.

if my 3 gig ddr2 667 memory transfer rate is much faster, i dont see the benefit of using readyboost and having it push files around at a whopping 8mb per second.... maybe it'll actually have the opposite effect of slowing things down?

i dont know what brand this memory is so i cant really look up specs.

 

Your ram has a peak transfer rate of 5.3GB/s

compared to 8mb lol

 

He has 3GB installed. That means 1GB + 2GB and results in FlexMode.

Peak Memory transfer:
DualChannel DDR2-667 = 2 * 64Bit * 333MHz * DoubleDataRate = 2 * 64 Bit * 333 MHz * 2 = 10,6 GB/s

However you're limited by your FrontSideBus:
FSB800 = 64 Bit * 200MHz * QuadPumped = 64 Bit * 200 MHz * 4 = 6,4 GB/s

Regarding ReadyBoost: If you only have a 1GB Module it's worthless. Even if you have 4GB, it doesn't pay off immediately. It's more space than your main memory and it's biggest advantage is access time compared to a hard drive. It serves only a cache for the hard drive.

However SD-Ram can be pulled off the notebook. TurboCache can't and therefore the contents of the flash survives reboot, standby, suspend, ... TurboCache has been more effective therefore (although same technology). The current status on benchmarks, using fast card adapters and sd-discs is unknown to me.

 

I was refering about a single stick/channel, no need to confuse the OP over a simple question.

My point was Readyboost is nothing compared to real RAM.

 

any of you guys use it using the built in sd card reader?

 

Well DDR2 667 Mhz is called PC2 5300 ... this means it has a transfer rate of 5.3 GB/s

 

Ill be straight forward with you, ive tried it before with 2gb RAM and the gains were next to nothing. Do not waste time or money with Readyboost.

Only systems with 1gb RAM or so will benefit on it.

You forgot dual channel, thats why 7oby came up with 10.6gb, double the bandwidth.

To make it even more complicated.. Intel flexmode. Meaning the the last gb on the 2gb module will only run single channel. Only the first 1gb on both modules will run dual channel. Thus 667 * 8bytes or 64bits * 1.5 = 8gb/s peak bandwidth, not 10.6ghz (data rate x data transfer x channels)

But in the end its bottlenecked by your processors FSB anyway. It cant communicate fast enough.

 

u know its a shame there isnt a website that u can put in all the specs of your computer that ur building that will tell u what the bottleneck is and what the spread between the components are performance wise...... all this talk above is appreciated, but the avg joe shmoe cant get it easily ya know?

 

What are your exact specs? and for what use? (gaming/encoding/etc)

Well i tried to keep it simple but that got out of hand

 

its for gaming, i have a 2.4ghz with 3 gigs ram, 320gig 5400 rpm, nvidia 8600m gt, its a m1530........ i dont think the ram is a throttleneck cause its probably more than enough, i am beginning to think the throttleneck in my system is probably the slow hardrive... what ya think ?

 

Your system seems to be pretty even. Your RAM can communicate faster than your CPU, thus the talking above. Your 320gb 5400rpm HD is equal to a 200gb 7200rpm (due to platter density).

For gaming, your GPU will be the bottleneck. Everything else is up too speed. Sure it will improve a little by upgrading your hdd to a 320gb 7200rpm (faster loading time) or 4gb RAM but in the end your GPU thats limiting your total performance.

Unlike encoding, you only need a faster CPU and faster HD for if you want quicker encoding times.
