@MuslimEgyptianWProud Thank you. I do have a new video "PC memory tutorial" with details and explain the terminologies associated with system memory. -MrFixit

...i have 2 kingston ddr2 800mhz but one is wider than the other...it has the same product serial...is it possible to get them to dual channel?

[ESRepair]

@DJOxyzen Check to see that they also have the same number of IC chips on both sides. they must be exact in every aspect to work in Dual-channel effectively. -MrFixit

hey man thats a pretty good computer. my comp specs are: 1 GB graphics ATI RADEON 5670 , BIOSTAR Motherboard with Quad Core 2.8GHz Phenom II Max Ram is 16 GB but I have 8 Gb installed. The Mother of my computer would be the hexacore by AMD. The ram it can support is up 32 GB. So what im asking is why won't windows register the other 16 GB if its installed?

[ESRepair]

@scottbarnner It mainly depends on the specific OS installed and whether it's a 32-bit or 64-bit. I use the 16GB limit because many Home PC's OS is Home Premium or less. To access above 16GB, the BIOS must support it and must install a Windows OS that supports >16GB system memory. Example: Vista 64-bit Buisness & higher supports up to 128GB, Win7 64-bit Pro and higher supports up to 192GB. Go to Microsoft's website a do a search for 'Memory Limits for Windows Releases'. -MrFixit

with an BIOSTAR A870 AM3 AMD 870 SATA 6Gb/s ATX AMD Motherboard would i be able to add TWO sets of Kingston HyperX Blu 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 Desktop Memory Model KHX1333C9D3B1K2/8G?

[ESRepair]

@REMlXX Yes. The motherbard will support those modules up to 16GB total under a 64-bit OS. Must use either an AMD Phenom II, Athlon II, or a Sempron 100 series processor that supports 1333MHz memory clock speed to obtain full bus speed, otherwise, Motherboard drops to 1066MHz. -MrFixit

[REMlXX]

@ESRepair thank you for the info, you rock!

[REMlXX]

@ESRepair AMD Phenom II X6 1055T Thuban 2.8GHz Socket AM3 125W Six-Core Desktop Processor HDT55TFBGRBOX would this be good?

[ESRepair]

@REMlXX Yes. Good choice. This processor contains a Direct Memory Controller that allows the memory to be accessed directly by the CPU without the North Bridge. This processor along with your Memory modules can achieve up to 21GB/s data bandwidth. It will also provided up to 37GB/s processor to system of data bandwidth using HyperTransport Generation 3.0 mode combined with your memory modules.-MrFixit

nice man :) i have 4 modules of 4 gb each one (exacltly same brand, clocks etc) , and i want to put them on 4 ddr3 sockets, soo the only thing i have to do for dual channel is put them ? in the order i want? thx.

[ESRepair]

@TACOonSTEAM Yes. The only time you need to be concerned with their order of placement is when there is an empty socket left or using different paired modules at which you'll need to read the motherboard documents to identify paired sockets. Keep in mind that Windows 32-bit OS max at 3GB and 64-bit max at 16GB. -MrFixit

[TheChrisapalooza]

Nice shop dude!.. Do you repair them for a living or just keep them all?

[ESRepair]

@TheChrisapalooza A little of both. The shop is whizzy's where we do most of the videos. I build and rebuild PCs for friends, family and help maintain them, including WhizKid's computers. -MrFixit

[mojo8210]

The first matched pair go in slot 1 and 3, the second pair uses slots 2 and

4. The slot closest to the CPU is usually slot 1 and slot 3 will have the

same color as slot 1. Slots 2 and 4 will be the other color.

[ESRepair]

@mojo8210 That is true w/ some motherboards, but, not all manufactures abide by those rules. Take Gigabyte's ga-990fxa-ud3 motherboard. It supports dual-channel but All 4 slots are black and #'d in reverse alternate order (4, 2, 3, 1). Here slot 1-2 are channel 0 and 3-4 are channel 1(manual pg16). It's important to read the manual to know which slots to use. I use to follow those rules till I helped a fellow viewer who has this motherboard. -MrFixit

[ESRepair]

@Daveze0920 be sure the memory modules are EXACTLY the same and they are seated properly. If the modules are the same and niether work in slot 2 indicates bad motherboard. -MrFixit

[theSONESTARtv]

hi i have a acer aspire t630 with dual channel i have 2x 1gb and 2x512 mb

i put them in like this:

1GB 512 MB 1GB 512 MB

normally I should get 3 GB right ?

but it says that I only have 2GB

please tell me why and by the way 4GB are the max 1GB max a slot :)

[ESRepair]

@theSONESTARtv Your PC's BIOS should identify 3GB of memory. Your PC must use either DDR2 PC2-5300, 6400, OR 8500. Paired memory moduals must be identical. Pair memory sockets will have the same color. Check to ensure the moduals are properly seated. You may have a bad modual or a bad socket. Some BIOS will indicate memory in each socket. If the mention above are correct but still only 2GB show, send me a personal message and I'll walk u thru the steps to find the problern. -MrFixit

[theSONESTARtv]

@ESRepair Thx for that fast answer, but I tried something. I put out one 512 MB ram and change the order of ram that looks now like this

1GB 1GB 512 MB

And after booting the Pc he shows me 2.5 GB yeah ;)

but my QUESTION is why not 3GB ???

Can it be of the Version of Win7, because I heard that 32 -BIT versions can`t handle more than 3 GB

and may in my fall it can only handle 2.5 GB so should I change to 64-BIT ?????

[amramr0182000]

thank you man :)

[TheSemperXFi]

Do all for Ram sticks have to be the same or just the same for each slots (e.g. 2x2GB in yellow 2x1gb in red)

[ESRepair]

@TheSemperXFi Basically the requirement are for the moduals to be idententical in paired slots (i.e. Moduals in the yellow slots must match in SIZE, TYPE, and SPEED). But better performance if all moduals matched. -MrFixit.

[TheSemperXFi]

@ESRepair thanks, that helped alot, also i have another quest about a problem i am having, when i turn my computer off the LED fans stay on (they slow down and go much dimmer but keep spinning) its not the power supply i had a Thermaltake® 450 when it started but i upgraded to a gigabyte® superb 550w but the problem persisted.

[ESRepair]

@TheSemperXFi Your welcome. As for the fans, if they connect to the motherboard, then something is faulty on the board. However, be sure the computer isn't entering sleep or standby mode. Power light will either flash or change color to indicate the pc is in sleep/standby mode. Many motherboard control the speed of the fan using Pulse Width Modulation in sleep/standby mode to preserve power and reduce noise. -MrFixit

[TheSemperXFi]

@ESRepair Thanks for the reply, and Yeah i just checked its my motherboard, The only fans the keep spinning are the ones connected to my motherboard, I'll connect all the fans to my Power Supply until i cant afford to buy a new motherboard in about 4-5 Months. Thanks

@TheSemperXFi Anytime. If you need.anything else, you know where to find me. -MrFixit

You really need to learn to set your audio recording options to mono when using a single microphone, or learn to fix it in post before you upload.

[novoiceless]

lol have you ever try to brake one of those damn things? try it you see what i mean lol

[ESRepair]

@novoiceless lol. No, I can't say I have. They are durable, however, you can damage the contacts or nearby modules if you were to slip. -MrFixit

[andy72xbox]

One Question, if a motherboard says it supports triple channel, can i still use paired dual channel ram?

[ESRepair]

@andy72xbox Yes. The rules apply to Triple channel the same way they do with Dual channel. ALL modules must be an exact match. The motherboard design is what allows for dual or triple channel modes. Depending on system design, you can use either DDR, DDR2, or DDR3 modules. -MrFixit

[andy72xbox]

@ESRepair just to make sure, so i can use dual channel on a triple channel mb

[darkj3am]

i just bought a new ram and found that it has to be exactly desame with my allready installed ram-_- it means same brand and everything?? not just MHZ, size and volts? same fucking brand!! FUCK i get errors when i install them together... i cant return the product either shit!

[ESRepair]

@darkj3am Everything must match.... The type, size, and speed must match. I only recommended that the manufacture match as well to ensure compatibility. The modules are paired together as to why they must match.

[remix696]

Awesome. Simple straight to the point and got my question answered. i work for dell, now and just tested 2 1x Gb sticks on my Dell XPS 720 and got no post just beeps and had corsair ram 2 x1 Gb stick up top, like blue and black had my corsair modules. now seeing this and knowing i have dual channel, im gonna move the corsair down. 1 x gb on the blue and 1x gb on the other blue one. and then kingston on black 1 and black 2. i think haha

[ESRepair]

@remix696 To ensure that Dual-Channel works at peak efficiency, ALL 4 modules must be exactly identical including the manufacture. As for the beeping w/ no POST, indicates another problem which may be one of the modules. One of the first POST is the memory. If the Motherboard can't read the memory modules it gives continuous beeps or it's a Chipset problem. Be sure you are using either 667MHZ or 800MHz DDR2 modules for your PC model. The motherboard defaults to the slowest module.

MrFixit

[remix696]

@ESRepair ok gotcha. i had the corsair, 2 of them were built with my pc and there the exact same the other ones i think different brand. i think your right, but it wasnt a module. 1st i thought it was, switched slots and it worked. then i thought no its my motherboard! switched again and it worked. so i assume its because theres that last ram thats a different brand. 6 beeps i should google it, but it was a test and you helped also. thx

[ESRepair]

@remix696 Anytime.

[Telelikeitis]

Thank you very much!
