ocz reaper ddr2 9200 vs Asus p5e ws pro

[saibhy]

hi

thanks for looking on this,

I was going to upgrade my ram to ocz reaper 2gb ddr2 9200 which has 1150mhz speed (memory info link OCZ DDR2 PC2-9200 Reaper HPC Edition review )

 

but i am confused because my motherboard asus p5e ws pro supports upto 1066mhz native and 1200o.c so will that ram memory run normal or i have to mess with overclocking tools ? which i don't know how to lol.

Hi

 

You can go here and it will tell you what RAM your motherboard takes:

Crucial

It will run - but will run alot slower than it should - you will not physically notice the difference though - get the OCZ PC 8500 and save yourself some cash. you can get 2GB of it now for around £55

thanks for that, i have now bought and installed 2x2gb of ocz reaper pc8500 1066mhz. But its recognised as ddr2 800mhz so Dalo do you know how to fix this so it can run on its full potential.

[Dalo Harkin]

set the timing manually in the BIOS to 5-5-5-15 with a 42 refresh rate and Manually set the Voltage on the DDR2 to 2.1 Volts

[saibhy]

Yep jus did that, but its still the same in my bios it says ddr fsb - ddr2 684mhz and it goes upto 910mhz but not 1066mhz, i used the software with mb called al booster which u could select 1066mhz after the reboot its stll hows around 910mhz nt more than that.

[Dalo Harkin]

Ok you have to set the memory divider at 1:1 so that the memory runs at the same speed as the processor (1066)

Or you can set at 1:2 and run the memory at 533 (which is also 1066)

see which is more stable on your MOBO I am guessing the 1:1 is better on ASUS

[saibhy]

where do i do that ? and btw my proccessor fsb is 800mhz (intel dual core 3.0ghz 800fsb

[Dalo Harkin]

a 3 gig, 800MHZ chip - is it a pentium D or somethin?

you need to work out the divider of the memory to run at 1066 - they are in the AI jumperfree configuration or something like that.

read the Manual and you are after the settings for the CPU multiplier and they are all located on the same page.

[Dalo Harkin]

have a look on the OCZ website on their forums - I am sure you can get these modules to run at 1200Mhz that woudl make it easier as you then need a memory divider of 2:3 think that you have to up the volts quite abit though - these modules are a 'pain' to set up, have you installed the latest BIOS that should do it all for you.

The below is off the OCZ website for these modules.

Hi Dalo Harkin,

 

Sorry if its not cool opening an old thread but im struggling here and youre the my best bet so far.

 

I built a system with the same cpu, mb and ram as you, PLEASE tell me if you still can, what your j. config. bios settings are?

 

Im really struggling with stability here!

Hi D1egend, and welcome to Extreme Tech Support - Free PC Help.

I will leave this in case Dalao spots it and gets back to you, if not I suggest starting a new thread and describe in full exactly what your problem is, it may not be related to these now out of date posts above, there may well be newer drivers available or other updates anyway.

 

I won't move this post, as on its own it does not convey enough information.
