Will the TWIN2X2048-6400 work with my motherboard ASUS M2V (VIA K8T890)


(not the M2V-MX), at 800 speed?


I can't find info about the M2V motherboard with 'Corsair Memory Configurator',

and ASUS 'Qualified Vendors List (QVL)' only lists CM2X1024-6400PRO and

CM2X1024-6400C4, not just 6400


I will have an AMD Athlon64 3800+ 65nm 45W stepping G1 processor

ADH3800IAA4DE/ADH3800DEBOX (2400 MHz, 2000 MHZ System Bus)



On the resellers webpage for the TWIN2X2048-6400 they say

"verified to operate at 800MHz at the low latencies of 5-5-5-12-T1."



but on corsairs webpage http://www.corsair.com/products/xms2.aspx

it's "TWIN2X2048-6400 PC2-6400 2GB Kit 5-5-5-18"

with 18 instead of 12, is http://www.webhallen.com wrong ?

I would suggest VS2GBKit667D2 with that MB, as it will not give you the option to set the memory Voltage and the modules you asked about would need 1.9 Volts Minimum.


but in the Users Guide for ASUS M2V there is mentioned a bios setting "DDR Voltage"

with the possible configuration options [1.80], [1.85], [1.90], [1.95]

that is possible to use if I set "AI Overclocking" to [Manual] ?

(and I assume that I don't have to acctually overclock the cpu to use

the memory setting, and can keep the FSB Frequency at default 200)


As long as the TWIN2X2048-6400 don't need more than 1.95 Volts

I should be ok then?



A related question, is the heat generated by the the two memory modules

significant for the computers total heat generation, so it will need more

cooling? I am trying to build a somewhat silent computer (within my limited

budget and still have a computer with ok speed)

Will this memory noticeable increase the cooling need, and I should

try to find some other (1.8 volt but still PC6400?), or is different

memory modules different heating insignificant? (the computer will have

an AMD64 45W and a Geforce7600GS/256MB/400MHz silent)

If your MOBO will supply 1.9v, then the memory you chose should be fine. As to the heat, you need to make sure that your case has good airflow thru the case. These are relatively low voltage modules so the video card and CPU will produce more heat than the memory.
