4 1024mb 1066 ddr2 only running at 667

Saw in the manual it only recognizes 1066 in the black slots. so if the 1066 is in the other slots does it down grade all of the memory to 667. if so can i over clock them or do i need to get rid of the 4 sticks and buy 2? is it faster if i get rid of 2 sticks at get the 1066 or keep the 4 and only run at 667? any suggestions appreciated.

Yes if all the sticks of ram are not the same it will downgrade the faster sticks to match.
1.Buy two sticks to match the faster ones
2.Id run 4 at 667 personally, if you multitask it might be best.

    Yes you can only install memory that is 1066 mhz in the black slots (which is very odd that only two channels support it)
    If you use 4 sticks the two channels that don't support 1066 cannot be overclocked, and the two sticks in the black slots will be downgraded to match the memory in the yellow and orange slots.


  • Quickfx PC Repair Jan 05, 2009

    You can basically use just the two sticks in the black slots, and they will run at 1066mhz..

    You can sell all your memory and buy (2) 2 GB sticks and use just the black channels.

    Keep the memory you have and let it run at a lower clock speed.

Asrock g31 m motherboard will only post if only one ram slot occupied , will not post if both slots are used , identical matched pair of ram ddr 667 800 mhz crucial ballistix both tested in another ri


I did some research. You didn't say what density the RAM was, but everything I can find on the Ballistix 800 MHZ DDR2 states that it runs at 2.2V. The standard for DDR2 RAM is 1.8V. You motherboard has both and AUTO and manual setting capability for memory (DRAM) voltage. It is possible that the AUTOP feature is not detecting the need for 2.2V, and that with only one DIMM installled, the memory marginally functions, but with the extra loading of the second it will not. Boot the system with the single DIMM, go to the BIOS, and set the DRAM voltage manually to the 2.01V setting (Verify by the part number of the RAM with the CRUCIAL website that is uses 2.2V before doing this). Once you have changed the voltage in BIOS, shut down and add the second DIMM and see if things improve.

Want to add ddr3 memory to my p5qc board


Hello
The motherboard supports DDR3 1333/1066/800 MHz or DDR2 memory 1066/800/667 MHz to meet the higher bandwidth requirements of the latest operation system, 3D graphics, multimedia, and Internet applications. The dual-channel DDR3/DDR2 architecture doubles the bandwidth of your system memory to boost system performance, eliminating bottlenecks with peak bandwidths of up to 19.2 GB/s.
DDR2 1066MHz DIMMs work only on the black slots for one DIMM per channel
2 x DIMM, Max. 8 GB, DDR3 1333/1066/800 Non-ECC,Un-buffered Memory 4 x DIMM, max. 16GB, DDR2 1066 / 800 / 667 MHz, Non-ECC, Un-buffered memory Dual channel memory architecture When installing total memory of 4GB capacity or more, Windows® 32-bit operation system may only recognize less than 3GB. Hence, a total installed memory of less than 3GB is recommended DDR2 1066MHz DIMMs work only on the black slots for one DIMM per channel. Ensure to install the DDR2 1066MHz DIMMs ONLY on the BLACK slots! Refer to www.asus.com or this user manual for the Memory QVL(Qualified Vendors Lists). When installing total memory of 4GB capacity or more, Windows® 32-bit operation system may only recognize less than 3GB. Hence, a total installed memory of less than 3GB is recommended.
Hope this helps

This board has a dual channel memory. To function correctly both channels must be identical otherwise , as you can witness, it chokes. To put it simply you must put either 2 identical sticks of memory or 4 - it can't run on 3.

Toshiba satellite A100 slot 2 doesn´t work. A


Is memory matched (DDR2 667)

Have you put original mem in slot 2

Download / install CPU-Z with both modules in and run program to see if it shows.

If all above is correct may be damaged mobo.

This is for your laptop from vendors site.

I am using this ASUS (asus M2N-MX nvidia mcp61p chipset


According to the manufacturer's web-site:

http://usa.asus.com/product.aspx?P_ID=0pKBwEIE8tqMT4j7


this motherboard has 4 x DIMM sockets,
supporting a maximum of 4 GB
of DDR2 800/667/533/ Non-ECC, Un-buffered Memory

and supports Dual Channel memory architecture.

So, add one 512MB DDR2 533 Mhz RAM into one of the slots,
being sure to leave *ONE* *EMPTY* slot between the two sticks,
in order to enable the high-performance "dual-channel" option.

Try your computer -- it should feel faster.

If you still think that need more RAM, buy two 512MB (or two 1024MB) DDR2 533 Mhz RAM, putting the 2 sticks into the two empty slots.

Cant pick both RAM same time


hopefully you inserted two similiar 1 GB RAM memory devices by the same manufacturer into the right slots 1

you may have a board that:
- has four slots available (two + two)
- but supports only a maximum of 1GB (two similiar 512mb devices)
or
-supports only a max of 2 GB of the same kind and same manufacturer,

so inserting all u got and hoping the PC does the memory management might not work!

please see the mainboard manual (if u have one) or download it from the manufacturer's site.

DDR3 RAM


According to your description you have 4 memory slots and each memory slot can hold
DDR2 PC2-6400
DDR2 PC2-8500
DDR2 PC2-5300 with a maximum of 2GB per slot.
This board does not support DDR3.
I hope this helps your memory question.

all memory will operate at the slowest speed chip unfortunately. the only way to get the higher speed is to have all chips capeable of that particular speed.
