I have the following

asrock p45r 2000
wolfdale e7200 (1066) cpu multiplier 9.5@ 267
4gb ddr3 1333 ram

From the bios stock my FSB 267mhz
1:1 dram ratio

So my ram is running at 267mhz .

If i run a fsb 333 my cpu is 3.1ghz...my ram only runs at 333mhz...isn't it suppose to be at 667 mhz?

The bios doesn't let me lock my dram frequency and i'm stuck tbh

How do I get my ddr3 ram running at its correct 1333mhz.

I'm very new at OC..
 
if you are looking at ram speed in cpu-z, then that's fine as the 333mhz reported is doubled for actual, for example I run 1600mhz ram and cpu-z shows it as 800mhz, scratch that I just noticed it's 1333 ram. Where are you reading the ram speed from, if it's the bios, use cpu-z instead. Also are you running the latest bios.

Your not going to be able to lock dram because as you raise fsb for the cpu overclock it also raises the speed the ram runs at, the idea is to use a ram setting below your optimal speed, and overclocking the cpu will raise the fsb and raise your ddr speed back up again.

As your cpu is 266, raise fsb to 333 to match the ram and with the right vcore you should be running 3.16ghz with no overclock on the ram.

yes the readings are from cpuz..

my comp just blue screened.

my frequency for ddr3 1333 i presumed would be at 667mhz

if my FSB is set at 333 and it auto increases my ram frequency...is 333mhz correct ? does it mean 333x4 thus giving me 1333 ?

the only stable Oc ive achieved is 280mhz fsb...this is pants as everyone with this combo (e7200 asrockp45r ) seems to achieve fsb's up to 400mhz which i presume clocks the ram to 1600

I have stable temps even the short try at 333fsb never went over 50c

my knowlwedge is not briliant but i followed these steps from scratch any assistance is most welcome
-------------

set mobo jumpers to 1600 to allow clocking (recommended)
cpu running at 1066 stock 266.7 x9.5
ram running at 1066 even though its rated 1333 and the mobo restrictions removed.

So i assume as having a 1:1 ratio...(previous 3:5) that increasing my FSB to 333 would bring my ram upto its correct speed 1333.

I've i got those facts right or am i wrong?
 
1:1 wont work with that - it only doubles the speed shown my cpu-z not quadruples.

Make sure you've put the appropriate voltage through the ram and set the speed to 667 which should give you 1333.
