tl-62 and 800mhz memory

does amd turion tl-62 support 800mhz memory?

 

Yep.

But it's always a good idea to check your manufacturer site first to see what they have to say. Sometime even though the chip can do it, the laptop itself can't.

 

what do u mean "the laptop itself can't"? i checked the manufacturer site and they say my spec memory type is ddr2 667mhz but when i check with cpu-z, it say that

max bandwith : PC2-5300 (333Mhz)

does that mean i only have ddr2 333mhz memory? how to know if the laptop itself support 800mhz and can use the 800mhz and not stuck at 667mmhz?i'm thinking to upgrade my memory to hyperx ddr2 3gb 800Mhz.is it worth or am i just stupid thinking something like that with turion tl-62?

 

Nope - you've got 667 MHz. DDR2 stands for Double Data Rate 2 - so you take the actual data rate (333 MHz) and double it to get the effective rate - 667 MHz.

Not sure what JohnnyFlash means by "the laptop itself can't" - I've yet to hear of a laptop that can't support the type of memory it's chipset is built to support. I can't see any reason why it wouldn't support it.

 

AFAIK, AMD's Kite Refresh Platform supports DDR2-800. (Checkout wikipedia)

If you can figure out, which platform your notebook is based upon, you'll be able to find out whether your notebook supports DDR2-800 or not.

Sometimes, CPUs support a higher FSB, but the BIOS or MCH can have a hard-coded mutliplier which won't let the DRAM:FSB ratio become 2:1.

Probably thats what JohnnyFlash meant, the CPU does have a higher rated-FSB (or HT) of about 800MHz, but the motherboard or chipset or BIOS may not support a multiplier of 2 at that FSB.

BTW, performance difference between DDR2-667 and DDR2-800 is ng. (you won't notice any change in performance).

And, if you're upgrading to a larger memory size, you can try out the DDR2-800 modules, since they more or less cost the same, and if DDR2-800 is not supported, it will downclock to DDR2-667. (Unless the BIOS does not like DDR2-800)

 

i've checked the wikipedia and it seems that turion tl-62 support ddr2 800mhz.i wanna ask about hyperx memory.

how it is different from other memory?

what's the pro's and cons using it?

how much it affect performance of turion tl-62?

 

Hyprex memory is just branding.

 

HyperX is Kington's high performance memory brand. It is similar to Crucial's Ballisitx, and Corsair's Dominators.

 

not...i mean does i get more effect when i use hyperx?how much percentage i get?i use 667

 

Almost nil. HyperX memory has lower timings, but literally no performance difference when compared to standard value memory, in the sense you'll never notice it.

Go for the value memory modules, which come with a lifetime warranty. Crucial makes good modules, and is IMO the best in after-sales support.

 

HyperX is just a marketing term, to make you feel like it is "high performance" memory. There is no real difference between regular and "hyperx" (or whatever other brands call their performance memory) in notebooks because the memory runs at its rated speed. Those marketing terms are basically better suited for desktop memory since people buy higher quality memory to make it run beyond its rated speed. In the notebook market, higher quality RAM doesn't matter vs. value RAM, unless it has a lower CAS latency. That's all.

HyperX does have a lower CL rating, but its not that useful in a couple of ways.

Firstly, the performance boost is minimal, and even there'll be a slight boost in synthetic benchmarks, one would never notice it generally. For general system performance, HDD speed matters more.

Secondly, it'll be hard to overclock the FSB. Lower CL - faster data fetch. Higher CL - greater stability, esp when overclocking.

Anyway, overclocking or not. Lower CL or HyperX memory is a waste of money IMO.

 

so,its not worth for me to spend on hyperx memory?
what's the point they make the hyperx memory if it make no literally difference in performance?

 

Marketing. They want you to think you are getting something really good when you buy from them. These marketing terms really apply to the desktop market because that is really the only place where memory is pushed to the limits, and good RAM is necessary to do that. Buying cheap RAM is fine for laptops if it fits the speed requirements fine, but I still recommend buying it from a reputable manufacturer like Corsair, Crucial, G.Skill, Kingston, A-Data, PNY, etc. If you have found a manufacturer and you want us to tell you if it is reputable or not, feel free to ask.

ok,thanks for all
