dual channel memory

[Empty_5oul]

I have dual channel memory in my 64 system but it doesnt seem to be any faster than my "normal" memory in other machines.

How do i check to see if dual channel is enabled and / or working, from when i set my machine up i cannot remember seeing or setting anything to do with the memory.

I can't tell for sure but maybe in the BIOS settings? It's usually there where everything "low level" can be configured.

thanks for such a quick response i had a quick look but found nothing stating dual channel on/enabled or dual channel off/disabled

Mine shows Dual channel during the POST checking.

Yeh my BIOS also says dual enabled a line like:

DDR Memory Clock: 333MHz (Dual-Channel Enabled)

If yours doesn't then look at the slots that the memory is installed in. The memory chips have to be the same size and clock speed (PC2700-333MHz, PC3200-400MHz, etc). Also, they have to be in certain slots. Consult your motherboard manual to find out which slots you have to put the memory in.

right i bought geil memory in a set, 2x 512's see here [ http://www.microdirect.co.uk/ProductInfo.aspx?ProductID=5608&GroupID=57 ] and my mobo [ http://www.microdirect.co.uk/ProductInfo.aspx?ProductID=7170&GroupID=527 ]

Yup, have to by them in sets, they are tested.
Did you buy them at different times? no good. :(

[Empty_5oul]

they are in a set so at exactly the same time and also manufactured at the same time, with same speeds and latencies + materials.

they can go in either of the two slots on my board, it can take 2 sets maximum ( 4 slots) and they are colour coded which i have re-checked and is installed sucessfully.

1GHz fsb?
am I missing something?
mine is ddr200 so, 400MHz fsb.

with what is this cpu talking to at 1GHz?

[Lagu]

Throught the system bus with 2000 Mhz. And The VIA K8T800 PRO /8237 Chipset supports I GHz Hyper Transport(tm).

Did you think it is impossible?

Lagu :D

[meckano]

ok, it is refering to the HT part.
phew, thought i needed a new computer. LMAO

29 secs each is pretty quick.

my scores were once that good but the i let some slower machines process some and my times were ruined :(
