Difference between DDR and DDR2
1. What is the difference between DDR and DDR2?
On the physical side, DDR has a 184-pin DIMM interface and DDR2 has 240.
DDR2 runs cooler and has generally slower timings but is a lot faster than DDR in the end. DDR2 is capable of holding more ram on one DIMM.

2.) Does DDR2 do more work per cycle? And Does AMD Support DDR2 Ram?
AMD doesn't support DDR2 as the A64's built-in RAM controllers would have to be upgraded therefore making them incompatible with all the current motherboards out there which really wouldn't be worth AMD and the board manufacturers' time.
The differences:
  • DDr1=184pin DIMM and DDR2=240pin DIMM.
  • DDR2 has much higher bandwidth and chip density/# of chips per DIMM, allowing more ram to be effectively used (also the reason why it's best to go for 1-2gb of DDR2) at a higher speed, but at the expense of latency.
  • On the other hand, DDR1 runs at lower speeds but much tighter timings

It is difficult to differentiate a DDR2 from a DDR motherboard just by looking at it.  Inserting a DDR2 DIMM into a DDR motherboard could damage the module, the motherboard, or both. To prevent such damage, the simplest process is to align the memory module and the socket, and visually check that the module “key” aligns perfectly with the socket key. You may have to turn over the memory module as the memory module direction may misalign even compatible socket and module keys.

3. What latencies will standard DDR2 DIMMs support?
JEDEC DDR2 specifications define standard DDR2 CAS Latencies of 3, 4, and 5:
– 400 MHz DDR2: CAS 3 (3-3-3)
– 533 MHz DDR2: CAS 4 (4-4-4)
– 667 MHz DDR2: CAS 5 (5-5-5)
4.: What latencies do Kingston HyperX DDR2 modules support?
HyperX memory modules support enhanced CAS Latencies:
– 533 MHz PC4300 DDR2: CAS 3 (3-3-3)
– 675 MHz PC5400 DDR2: CAS 4 (4-4-4)

Google’s Cloud Computing Phone application – translate text in real time

Google’s Cloud Computing Phone application – translate text in real time

Stumped by foreign languages when you’re traveling? Google Inc. is working on software that translates text captured by a phone camera.
At a demonstration Tuesday at Mobile World Congress, a cell phone trade show in Barcelona, an engineer shot a picture of a German dinner menu with a phone running Google Inc.’s Android software. An application on the phone sent the shot to Google’s servers, which sent a translation back to the phone.
It translated “Fruhlingssalat mit Wildkrautern” as “Spring salad with wild herbs.”
There was no word on when the software would be available.
Software that translates text from pictures is already available for some phones, but generally does the processing on the phone. By sending the image to its servers for processing, Google can apply a lot more computing power, for faster, more accurate results. The phone still won’t order for you, though — you’ll have to point at the menu.
The demonstration was part of Google CEO Eric Schmidt’s keynote speech at the trade show, the largest for the wireless industry. He said phone applications that take advantage of “cloud computing” — servers accessible through the wireless network — will bring powerful changes to the industry.

Smart GMail – Did you mean to attach files?

Today one of my friend noted a really unnoticed yet creative behavior of GMail. He tried to send an email with body containing “please find attached ….” and he clicked send, GMail instead of sending that email popped-up a message
Did you mean to attach files? You wrote “find attached” in your message, but there are no files attached. Send anyway?
This alerted him that he missed on attaching the files.
Isn’t that really smart and creative thinking! Though a minute thing, but such small things of intelligence makes GMail (Google) an innovator at email services.
Cheers Google!

Email Sheduling Coming On Gmail

Finally: E-mail scheduling coming to Gmail
No, not from Google, but from a browser plug-in called Boomerang for Gmail.
A company called Baydin sells a $14.95 product for Outlook called Boomerang for Outlook, which enables you to reschedule the delivery of e-mails you’ve received and also to schedule the sending of e-mails for some specific time in the future.
I’m sure Boomerang for Outlook, which I have not tried, adds convenience. But Outlook doesn’t need e-mail scheduling, because that functionality is already built-in.
Gmail, on the other hand, desperately needs it. Which is why Baydin’s Boomerang for Gmail will probably be very welcome. The product is a browser plug-in for both Firefox and Chrome currently in beta mode. If you sign up at the Baydin site, they’ll send you an invitation code. Or so they say. I’m still waiting for mine.
To use Boomerang, just click on a “Receive Later” button that the plug in adds. Then you select a date and time. Boomerang moves your message into Archives until the specified time, at which point it moves it back into your inbox, marks it “unread” and puts a star on it.
When in Gmail’s Compose mode, Boomerang offers a “Send Later” button. Clicking it lets you choose exactly when.
