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.

I have intel dg41rq motherboard with 2 gb kingston 667 mhz in one slot. can i put another 2 gb ram in other slot. if yes then should it have the same specification?


Intel DG41RQ Motherboard has two DDR2 (DIMM) sockets.
It Support DDR2 800 or DDR2 667 MHz DIMMs. Since you already have a 667 MHz RAM, it is recommended that you add another RAM of the same specification (DIMM DDR2 667 MHz)
However, if you add 800 MHz DIMM with 667 MHz, both would perform at 667 MHz. RAMs of different bus speed and latency usually work together but the performance is compromised.
It is always better to have RAM in pairs of same specification.

Hope it helps! Good Luck! Thanks for using Fixya!

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

My asus m3n78-em motherboard does not boots with 6 gb ddr2(3 chips of 2 gb) ram it works properly with 4 gb ram(2 chips of 2 gb) i dont know what to do it used to work properly before but its not working...


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.

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.

Upgraded my RAM to 2 x 1gb kingston KVR667D2N5 and windows XP will now not start. If I replace my old RAM, it works fine. Please help.


Your memory is not supported in Asus QVL = Qualified Vendor Listlist. There are only 4 Kingston DIMMs that pass Asus test for 667MHz. They are;
DDR2 667 512MB - E5108AE-6E-E
DDR2 667 1024MB - E5108AE-6E-E
DDR2 667 512MB - E5108AE-6E-E
DDR2 667 256MB - HYB18T256800AF3
Try exchanging the memory you bought for one of the above.
It wouldn't hurt to clean both sides of the memorys contacts. Two drops of alcohol onto a cotton sawb. Do not touch the contacts with your fingers.

RAM Memory Speed compatibility


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.

Qvc said my ram isnt on the list


From the Asus website - "DDR2 1066MHz DIMMs work only on the black slots for one DIMM perchannel. Ensure to install the DDR2 1066MHz DIMMs ONLY on the BLACKslots!"

Your motherboard only has two black slots. You can install larger capacity sticks of RAM in those slots, but you can only use two. Most likely you are getting the incorrect reading because you have four installed.

How can i run 1 or 2 DDR2pc8500 1066Mhz on a asrock 775dual 880pro< it booted,went to bios to down the speed to 667, but when windows(XP) tried to boot it went to a blue screen saying things about memory...


your motherboard supports DDRII 667/533/400 and DDR400

1066 is not supported, I have never tried to use a unsupported memory speed on a motherboard so I don't know, I know you lowered it to 667 but still the ddr2 which you have bought is not supported by default.

why buy too fast memory?
