Memory mismatch · DIGIT-ARC

My friend just got a new 512 ddr 333 Mhz memory module. He has an old one of 256 MB 400 Mhz. So i got that module from him. Now the problem is that my 512 ddr ram shows 132.9 mhz frequency. Now I have never heard of such frequencies , maybe I am ignorant. Nevertheless here is what cpu-z shows.

Now my 512 module can it pair with the 256 mb 333 mhz one.
And by the way my mobo is 845G

The memory is currently running in 266Mhz, coz 2*133=266. That is 133 is single path interleave. Its correct.
See in bios if the memory speed is set to 266, or r u sure the 512 one is 333.

If it runs on 333, then on cpuz itll show 166+-1~2

yep u can use both.. Currently ur 512 is running at 266mhz (actual 133mhz)..
If u use both then change the frequency to 166mhz in the bios (333mhz) and save it

I am not at all sure as to what my 512 module's frequency is, the bios shows 133 Mhz

You mean to say that I can use both modules by just setting the frequency to
133mhz

Come on guys just help me out. My 512 module runs on 266 Mhz. Now can I use a 256 400 mhz model with it

thats it

Intel 845 chipset supports only 266mhz DDR Modules. So whatever modules higher than 266mhz DDR (meaning 133*2mhz, as shown in your bios) are put in they'll down clock to 266mhz.

The 133mhz shown is correct in the bios as DDR = double data rate = speed * 2 = 133 * 2 = 266mhz.

The only problem you may face is the timing in-compatibility, which you can test with cpu-z. Try out the stick on your machine for some dayz.

@mad1231moody
plugin that 256 nd 512 nd set the frequency in bios as 133[if there is any option like that].
If there isn't ny option then they ll be automatically run at the frequency of the lowest speed ram, in ur case bothll run at 133, ie effectively 266 Mhz 768MB.

@infra, i think 845 supports 333Mhz ones also. Correct me if am wrong.

Unfortunately, No. It doesn't.

Yep the original Itel 845s dont support more than 266mhz. But My Asrock 845 supports 333mhz also. Which board do u hav exactly?

I have Asrock 845 mobo. Should I try to use

^^ Is it 845 GL or GV. GL supports only 266 Mhz max & GV supports 333 Mhz max.
My old mercury 845 gl agp mobo has option for set 333 Mhz mem speed in bios.
Even if I set them 333 Mhz with my zion 2x512MB ddr rams they always run @
266 Mhz. Confirmed it with many hardware tools like cpuz etc.

How do I find out, but cpu-z says it is 845G.
And friends I don't mind at what frequency it works, all I want is that to know that is it safe to use both of em.

Use tools like everest to identify ur chipset correctly

ya. it's safe to run both of them @ 266 ( 2x133 ) Mhz speed

Well thanks all of you'll. I have connected both the RAM's and they are working fine at 133MHz
