I'd really appreciate any help on this matter, not really being all that knowledgeable in the hardware at hand.
I am running a Gigabyte GA-MA69G-S3H (rev 1.0) motherboard with the latest BIOS, F6 I believe. The proc is AMD Athlon(tm) 64 X2 Dual Core Processor 4800+. The operating system at present being Ubuntu 8.04.1, fully updated and so forth.
(http://www.gigabyte.com.tw/Products/Motherboard/Products_Spec.aspx?ClassValu...)
The manual clearly states that the four DIMM slots run at a voltage of 1.8, this is also very clear in the CMOS settings. However, I have purchased a set of Corsair DDR2 800MHz XMS2 DHX, 2x2gb (http://www.ebuyer.com/product/142433) before realizing my potential issue.
In the extended specifications it mentions something regarding 2.1 volts as it also does on the side of the heat-sinks. They are both currently in this particular machine and seem to be working fine, my concerns arise when running a memtest via GRUB.
I have altered nothing in the BIOS merely replaced the old RAM and attempted to boot, which works fine, the memtest is stating something along the lines of 5-5-5-18, which I presume is related to the latency, however the RAM is branded as being 4-4-4-12, I am blissfully unaware as to whether it is running at the correct speed, or indeed voltage to work fully.
Another point would be the system only displaying itself as having 3.2gigs rather than four, although this I presume could be normal as I am under 32bit userland.
If my hardware will allow, of course, I wish to run this memory at its full capabilities. Any aid in this will be a great help.
Cheers,
Steve
