What is the difference between 667MHz and 800MHz RAM?
What is the difference between 667MHz and 800MHz RAM?
Distinguished. It’s more or less a capability rating. The 800MHz RAM is rated to provide data to the CPU faster than the 667MHz. However they can both operate at 667MHz or lower or even higher, though if its higher than the RAM is rated for its considered to be overclocked.
Which is the best DDR2 RAM?
Top 10 DDR2 RAM
| RAM NAME | PRICE |
|---|---|
| Kingston 1GB DDR2 800 MHz Laptop Memory | Rs.2,300 |
| 408854-B21 HP-Compaq 8GB 2x4GB DDR2 PC2-5300 ECC Registered DIMM | Rs.36,675 |
| 30R5150 30R5150 4GB 2X2GB DDR2 DIMM 240-pin LP 533MHz PC2-4200 1.8V 4-4-4-12 ECC | Rs.7,850 |
| Compaq/HP 2GB PC2-6400 DDR2-800 2Rx8 ECC DIMM (Compaq/HP PN# 450260-B21) | Rs.2,100 |
Is 667 MHz RAM good for gaming?
The short answer is yes. The ram has a delay whenever the CPU need to grab some numbers to crunch. Faster ram will make the numbers get crunched faster. If 667 Mhz is okay for you right now, I wouldn’t upgrade.
What is the highest clock speed for DDR2 RAM?
DDR2 speeds
| Friendly name | Industry name | Peak Transfer Rate |
|---|---|---|
| DDR2-533 | PC2-4200 | 4266 MB/s |
| DDR2-667 | PC2-5300 | 5333 MB/s |
| DDR2-800 | PC2-6400 | 6400 MB/s |
| DDR2-1000 | PC2-8000 | 8000 MB/s |
Is 800 Mhz RAM compatible with 667mhz?
Yes, you will benefit from 4gb. A 64bit OS (with 64bit apps)would make better use of that 4gigs. Its not really a good idea to mix different speed RAM, but it might just work for you.
Can I use DDR2 800 instead of 667?
DDR2 800 can run (and per DDR2 spec it does run) on 1.8v just like 667. All DDR2 “runs” at 1.8v.
Are all DDR2 RAM compatible?
Basically any DDR2 DIMM’s will fit. However, whether these DIMM’s are electrically compatible (with the motherboard) is another matter. Check with memory manufacturers and check the motherboard memory QVL for compatible memory.
What is 667mhz RAM?
667mhz is half of 1333mhz, which means that your ram is running at 1333mhz, which is standard. Just go in your bios and change it to 1600mhz, then it will show you are running it at 800mhz, which is the correct speed.
Can I put DDR RAM in a DDR2 slot?
DDR(1) and DDR2 are not compatible, so choose either one. There are motherboards (check Asrock) that can handle both memory types, but in different slots, and only one type at a time.
What DDR2 800?
DDR2 PC2-6400 (commonly referred to as DDR2-800) memory is DDR2 designed for use in systems with a 400MHz front-side bus (providing an 800MT/s data transfer rate). The “6400” refers to the module’s bandwidth (the maximum amount of data it can transfer each second), which is 6400MB/s, or 6.4GB/s.
What’s the difference between DDR2 667 and 800Mhz?
DDR2 667 (PC2-5300) = 5.3GB/sec in single channel 10.6GB/sec in dual channel DDR2 800 (PC2-6400) = 12.8GB/sec in single channel 12.8GB/sec in dual channel With respect to dual channel comparison, its a 133MHz difference which translates into 2.2GB/sec gain from upgrading to 800MHz
What’s the clock speed of a DDR2-800 Ram?
DDR2-800 is rated to run at an actual clock speed of 400.0 Mhz (800/2) The clock speed of the ram is driven by the motherboard front side bus (FSB), times the FSB:MEM multiplier in BIOS (some boards have lots of options, others none or few).
What kind of DDR2 RAM do I Need?
Well, there’s a small problem in that it is somewhat fickle in what it supposedly will accept. The board supports 533, 667, and 800 MHz DDR2 RAM, but it will only run at 533 MHz or 667 MHz if you put 8GB of memory in there. I’m using 1.5GB of 533 MHz RAM now (2 512MB dimms and 2 256MB dimms).
Which is better ddr2-860 or DDR 2-800?
So the DDR2-800 memory is actually being run faster than rated (roughly DDR2-860 430 FSB*2), but everything is stable… and the fastest machine I’ve ever used That makes it a little clearer. So what would the best multiplier be (I am guessing 1). So due to that, that is the reason why DDR2-800 memory is better? Click to expand…
