Geil Value Ram + Overclocking AMD 64 system

[YorkieBen]

I will hopefully be building an A64 939pin system in a couple of months.

My question is, is the Geil value ram a decent overclocker on the A64 system. Anybody here use it? Because I was hoping to keep the RAM cheap to get a nice graphics card

Any help would be appreciated

I don't have personal experience of Geil ram, however there's a review out there where they bought some geil ddr3200 and when they took the heatspreaders off discovered it was actually overclocked pc2700 :S

You could always use a divider to lower the speed of the memory. I've always found Crucial memory to be good quality and cheap, use "ComputerActive" discount code to get 4% off.

I recently got 2x512mb DDR3200 dimms from there for £93, have yet to install it.

Sorry could you explain to me what meory dividers are please? Thanks

Memory dividers allow your RAM to run async to your front side bus speed. Say you are overclocking a 3000+ chip, to get 2.25GHz out of it your FSB needs to be at 250MHz. Now your DDR3200 may not be capable of overclocking that high, so what you do is choose a memory divider.

Most commonly found is the divider 5:4. When your FSB speed is 250MHz, divide it by five and then times it by four. In this case, the FSB is 250MHz, the CPU is @ 2.25GHz, however the ram is still at it's native 200MHz speed

It is also used for people upgrading and bringing older, slower ram with them, such as PC2700 DDR in new A64 systems.

Is it not still the case that A64s hate running Async, even if the CPU is faster, due to the on-die controller?
