RAM Speed lower than rating
I am the noob of the day. I have a RAM issue.
Guess 1st some system specs:
CPU - AMD64 3500+
Mobo - ASUS A8N-E
RAM - 2x512 Kingston PC3200 DDR 400
- 2x512 Nanya Technology PC3200 DDR 400
When I only have 2 sticks in the slots my RAM speed reads @ 201MHz which makes sence to get my 400
However when I add my other set my speeds drop to about 165MHz or 333.
What gives? Can this be corrected?
It does not matter what set I put in, when it just one set I get full speeds. Only when I fill my slots my speed drops.
I have updated to the latest chip set and bios for my board and no change.
100% proof positive.
I have inserted the sticks seperatly, as pairs and all for in proper team slots.
Ran CPU-Z to confirm timings each setup. I have run Memtest on them for 1 hr to 150% with no errors. I will run mem test overnight tonight to get a full picture.
I have had this problem ever since I bough my 2nd set of sticks over a year ago. Took the sys to Greenlyph and they could not sort it out and said it happens sometimes. Not that it really matters as I am upgrading soon but it has really been getting to me lately as I am trying to learn how to OC on this system and have not been very successful. I strongly believe my RAM is holding me back.
With all 4 sticks in I get 2048MB Ram @
DRAM 158.0 MHz
FSB:DRAM CPU/14, 2.5,3,3,7 10 2T 16
board specs reads:
4 x 184-pin DIMM Sockets support max. 4GB DDR400/DDR333/DDR266 ECC/ non-ECC un-buffered DDR SDRAM memory
Dual Channel Memory Architecture
If I cant run the 4x400 would I be better of pulling a set out and only running 1G@400 vise 2G@333
Considering your using DDR memory I'm gonna say its not worth 4gb and just run 2.
Sorry but I am only running 4x512@333 so are you saying pull a set out and run 2x512 for 1G@400?
It doesn't matter because with DDR memory you won't see that much of a difference between 333 and 400 :)
So just leave it.
OK, thank you very much for your speedy replies. I can see I am going to like it hear. Especially when I get in to overclocking.
