Transcend DDR2-800 ECC

Has anyone tried the DDR2-800 ECC memory on a 597x?

I am planning on upgrading to the 800 and saw the Transcend with ECC which can be beneficial is the motherboard supports it.

If no one has tried it I guess I will have to be a guinea pig

 

the MB will downclock it to 667

 

hmm that is interesting.

I wonder if I can get an benefit out of the ECC atleast? That in its self can really help overall performance, if supported.

 

what's ECC stand for?

 

"ECC uses a special algorithm to encode information in a block of bits that contains sufficient detail to permit the recovery of a single bit error in the protected data. Unlike parity, which uses a single bit to provide protection to eight bits, ECC uses larger groupings: 7 bits to protect 32 bits, or 8 bits to protect 64 bits. There are special ECC memory modules designed specifically for use in ECC mode, but most modern motherboards that support ECC will in fact work in that mode using standard parity memory modules as well. Since parity memory includes one extra bit for every eight bits of data, this means 64 bits worth of parity memory is 72 bits wide, which means there is enough to do ECC. In fact, parity SIMMs are 36 bits wide (two are used in a fifth or sixth generation system) and parity DIMMs are 72 bits.

Note: ECC requires special chipset support. When supported and enabled, ECC will function using ordinary parity memory modules; this is the standard way that most motherboards that support ECC operate. The chipset "groups" together the parity bits into the 7-bit block needed for ECC. Many of these motherboards also support the special ECC-only modules, but some boards support parity modules in ECC mode but not the ECC-only modules. See this section for more on the difference between the two types."

Basically it tests the accuracy of the data as it passes in and out of the memory

What he said

 

Your laptop does not support it most likely. I am not aware of any laptop that supports this technology.

 

The D901C supports it and has for the past year that it has been out.

I believe the C90 also supports it but could be wrong on that one.

 

Well than I learned something today .

 

It's because the D901C uses a desktop motherboard chipset, the Intel® P965 + ICH8-R.

 

Note that ECC memory is ~2% slower, due to bit verification.

 

Thanks for all the info, made my decision a bit easier

 

No point, the RAM that came with my 5793 overclocks to 750 Mhz with zero error or heat problems because of my FSB overclock... (which of course overclocks CPU as well )

 

Yep will be playing around with that as soon as I get comfortable with my new beast
