Question about Biostar GEFORCE 6100-M9 Motherboard

Open Question

GeForce 6100-M9 Low or High density RAM?

I can't seem to find this anywhere. I have two 1GB high density sticks that don't work. I don't even get a splash when booting. I'm assuming that it doesn't take high denstity, but thought I'd ask to be sure.

    I'm not asking about a brand of PC. Knowing the model of a PC has nothing to do with what type of RAM a MoBo uses. I'm asking about a SPECIFIC MoBo. Nonetheless...I discovered that it takes low density i.e. 64x4 rather than the 128x4.

    badpots,



    The table in the manual only applies to the AMD K8 CPU launched before Rev. E. Since you have your sticks in a configuration not referenced in the table, and are working fine, I assume your CPU is after Rev. E or a different CPU altogether. I currently have 1Gig sticks in A1 and B1 plus 512 sticks in A2 and B2 (total of 3 Gigs) and they are working fine. I would put the Gig sticks in A1/B1 and the 256 sticks in A2/B2 (not sure if it matters, but I like the larger sticks in the 1st slots). Hope that takes your worries away.



    P.S. Just make sure you get low density sticks.

    I looked at the manual directly from the Biostar website and didn't see anything about all four slots needing to be filled in order to acheive dual channel. As a matter of fact, the manual is rather short and without a lot of technical info. As far as the how to get the 1Gb without high density...that's above my head. My buddy gave me memory, it didn't work. I looked up what was typed on the sticker, which was 128 X 4 and got a bunch of hits about high density RAM and that low density would have the 64 X 4 (which my working RAM does have printed on it). I did a google search on high vs low density RAM, but didn't get any answers that I thought were conclusive. There's still a lot of confusion on my part. Hope I didn't bore ya with all this rambling : )

    Well I've always wondered why memory configurators would only offer a few recommendations. I used Crucial's to narrow down the selection. I bought the 2 x 1GB kit CT2KIT12864Z40B. It is described as 128x64. All of the DDR's offered by Crucial (not just the recommended ones) are labelled x64 or x72(ECC). All of Crucial's 1gb DDR is labeled 128x. However, many hits online are referring to 128x64 as HIGH DENSITY. I find it hard to believe that all of Crucials memory is high density. I'm confident in Crucials recommendation but the information out there is not adding up.

    Well,as a matter of fact my revision is reported as E4. From the manual it would appear that dual channell is not achieved with an early cpu unless all four slots are filled. You mention 64 x 4 and 128 x 4, but how do you get 1gb on a stick without it being high density? Are those specs available? I haven't heard that description used for a long time.

  • badpots May 11, 2010

    The manual shows SingleSided,DoubleSided up to 1GB in all 4 slots, but only using both DIMMA's before filling the DIMMB's. Did you have to go with 512 sticks? I have answered a simular post regarding memory on this motherboard. I currently have (2) 256 stick's in DIMMA1 and DIMMB1. This gives me 512 dual channel as indicated by CPUz, but is not a combination shown in the manual. I was going to buy (2) 1GB sticks for DIMMA2 and DIMMB2 but now you've got me worried.

The manual doesn't show a combination of 3 sticks of memory. Only 1,2, or 4 sticks. Something to do with early CPU revisions.
DIMMA1 or 2 can be used individually or together, but both DIMMB1 and 2 must be filled if more than 2 sticks of mem are installed. The memory doesn't have to be the same in all 4 slots. However, what's not stated in the manual, is that if you want to enable the Dual Channel support the #1 sockets of both channels must be the same and likewise the #2 sockets. (not the sockets right next to each other) I don't know if Dual Channel can be run on one set and not the other. A free program called CPUz from CPUID .com will tell you if dual channel is enabled and everthing else you never knew about your computer. Go for (2) 1gb and (2) 512mb of the fastest you can afford. This puts you at the limit for 32bit systems.

Bah! That is just cra-zy!

Maximum TOTAL Amount is 2GigaByte. (2GB)
Maximum Amount for EACH ram memory slot is 1GB.

IF, you only have ONE ram memory module ('Stick'), it goes in Slot 1. (DIMM 1)
That is the ram memory slot closest to the processor socket.
The Processor reads ram memory Slot 1 first.

Hello sir/madam... I m using PI845GVM-AGP motherboard. Currently installed with 512mb ram and 2.13Ghz(Celeron) processor. Issue is, when i install 1Gb ram System goes through POST well but after loading...


I see 3 possibilities:
  1. While it may be the same MFG and same speed, the new ram MAY be high density chips and if you are using them with the original low density chips there may be a compatibility issue. (Some systems don't play well mixing single ranked and dual ranked chips etc)
  2. You may need to flash the bios to ensure compatibility with the new RAM
  3. The new ram is faulty.

Hi guys, i have installed 2 sdrams pc-133 512mb,together 1gb, but yhe bios and the system shows me only the half memory,whyyyyyyyy


Are you sure that both sticks of RAM are properly "seated"?

How much memory is found when only one stick is used?
How much memory is found when only the other stick is used?

Which motherboard? Some very-old motherboards only support a maximum of 256MB per slot.

How many memory-chips are on each stick of RAM?
If you have purchased "high-density" memory (small number of memory-chips),
and your motherboard only supports "low-density" memory, then only 1/2 or 1/4 of the actual RAM will be used.

Hi, I don't know if I should get single or double sided ram for this mother board, and is low density ram ok? Thanks, Wayne


This mainboard uses DDR400 memory


A High Density module is by far much slower than Low Density module at the same speed rating say PC3200/DDR400. High density modules are FAR CHEAPER, less than half the price when compare with low density modules and hence high density modules will NOT work on 90% of today's PC chipsets. LOW DENSITY modules have 100% compatibility with ALL systems and ALL chipsets. HIGH DENSITY modules only have 10% compatibility and are VERY SLOW.


So AVOID those 'High-Density - 128Mx4 config 1GB modules which is usually UNBRANDED and is NO NAME!


With this in mind it is far better to use low density Ram. Most RAM cards today are double sided, it all depends on the capacity of the RAM card.


Please rate this solloution as it it much appreciated.

Thanks.

I have intel d845gvs1 motherboard with P4 2.4 ghz, Currently have 2 ram (512mb & 256 mb) how much further can i upgrade the ram, 1GB or 2GB also is the current combination of ram is right?


"Supports up to 2 GB of system memory with DIMMs utilizing 512 Mbit
technology DRAM devices"-intel

you can use 2 sticks of 1 gig apiece to get to 2 gigs of total memory, but you have to make sure that the ram sticks use "512Mbit " technology.

the 512Mbit technology refers to the arrangement of memory chips on the ram cards. a card which uses 64Mx8 (8 seperate memory chips of 64M apiece) would be appropriate.

"Nearly all motherboards only recognize 1 GB modules if they are low density 64M×8 modules. If high density 128M×4 1 GB modules are used, they most likely will not work."-wikipedia"

Planning to upgrade my RAM(motherboard K7SOM + V7.5C). Ram have high & low density. What is the difference? Which suit my motherboard? Thanks.


Look at the sticks of RAM -- "high" density means fewer chips on each side of the stick, i.e., newer technology and production methods have packed more bits into each chip, while "low" density usually means 8 chips/side, using older RAM chips.

Older motherboards do not expect to find "high" density RAM, and typically will only detect 1/4 or 1/2 of the RAM on the stick.

If you buy a new motherboard, it will support BOTH densities.

Memory problems


Hi,
If you are sure your motherboard can handle a 1 GB RAM stick, then the general answer is that the motherboard can not run High Density RAM stick as yours is possibly. You might need to exchange it for a stick of Low Density RAM.

According to some quick research, it says your motherboard can only read up to 2 GB TOTAL of RAM even if you have more installed.

Many motherboards when booting from dual sockets wish for ram either of same manufactuer or same capacity per stick

Memory Stick Installation


So it seems you got the DDR / DDR2 side of the equation correct, but unknown to most, there is 'low' and 'high' density memory.

The density of memory refers to the number of chips used to make the total amount of memory that your memory stick contains. e.g. High density memory has few, large capacity chips to make up the 1024MB of memory on the stick, whereas low density memory uses many, small capacity chips to make up the same 1024MB total on the stick.

Typically, if it is a low / high density conflict, it is the 'low density' sticks only that will boot.

Me, I purchase Kingston memory when I'm unsure what the motherboard will be, and it has never failed to work.

I fix computers.
