    its on the old ram

  • niko07 Dec 06, 2007

    all the ram is compatible.i know.

    no beeps.the pc worked just fine with 2 gb.its on Vista 64,i downloaded the update 929777 to be able to get 4gb without a BSOD. I already checked all ram for errors,they were all fine.

    To me this looks like a motherboard error.I was looking for similar errors on google and "C1 error" came up and this fix from the evga forums

    Also its a:
    EVGA 68i LT
    Intel Q6600
    4x1gb patriot ddr2 800
    2x Seagate 320gb SATA II
    Windows Vista 64
    2x 8800 GT 512mb
    PC P&C silencer 610

    What is Error C1

    If you would read what i have written goovy75,i cant even go into BIOS...

  • niko07 Dec 06, 2007

    Since it doesnt POST,goes to BIOS or beeps,it could be the PSU.

    Its brand new,and its a PC Power and Cooling,one of the best PSU manufacturers so i don't know.

You also might check your version of your bios from your motherboard. If there is you can try upgrade your bios and maybe then all of them will work.

    You can go to bios if you just have 1 memory installed. Just temporarely to see what version your bios is and then check it on the website of you mobo manafucturer.

    You also said that it was working before you add the memory. So take it out check your bios version. After that we look further. step by step.

    i am not angy. it's just a mis understanding.

  • goovy75 Dec 06, 2007

    by the way c1 error means that it can't find the memory or identify it. What is the brand and model of your motherboard and what memory do you have?

    is it the list you provided here up?

  • goovy75 Dec 06, 2007

    well if you have a q6600

    2x 8800 vga

    2x 320gb hdd

    i would advise a psu of minimum 600 watt. 550 or 550 should be enough but a psu of 600w has a little more room to breathe.

    but let's not guess here. try first to see what happens. and i know it's not fun or easy:

    take out 1 of the 2 vga if you have 2. Unconnect the 2 hdd's from power and sata cable. leave only one memory dimm in the slot.

    turn on pc. if it shows bios and/or post. turn it of and then add one of the other that is unconnected. Then turn on pc. if you see post and/or bios turn off and connect te next. In this way you might see what is causing the problem.

I know you have probably confirmed that your motherboard supports 4 GB of Ram so I'll just to the troubleshooting.

If the computer sends out 3 beeps when turning on the computer without posting you know that there is a memory problem.

Try to start out with the original ram to make sure the computer boots. Then add each stick to see when till the computer fails if the first added stick fails remove and try the other new one. If they both fail the memory may be incompatible with your system. If one stick fails then your problem is most likely a bad ram stick. Although it is possible if both ram sticks fail and have them both be bad ram it is not as likely.

Does it boot fine if you remove the memory you just added? If it does then try switching the memory that was in it before with the memory you just added. You want to first determine if the ram you bought is bad or incompatible.

I recently added 2 sticks of 1 Gb Ram to my desktop, to now have a total of 4 1 Gb sticks. This newly added memory is PC2 @ 5300Mhz speed. The older 2 sticks of 1 Gb memory are PC 2 @ 6400 speed,...

It depends on what you would like the end result to be. If you need to multi-task, and have 10 windows running at once, go with the 4GB @ 5300 because while it might take a little longer your computer will still be able to handle all the information. However if you are just using it for light browsing and would prefer speed over bulk (when it comes to data processing) go with the 2 @ 6400. I don't think it would be worth it to get 2 more @ 6400, technology is advancing so fast. If you have 60 bucks you can upgrade to two 4GB @ 10600 (8GB total for $60) 1333MHz PC3. Lookup Corsair XMS3 4GB RAM.

Have asus p4s8x mob,when adding 3rd stick of memory (1gb) total of hangs on startup 1long 3 short beeps. if i remove one old stick and leave new with old (2gigs total)it works fine,also works...

The Asus Asus Motherboards P4S8X-MX uses PC-3200 type memory and usually ships from Asus with 0MB of RAM. The Asus Motherboards P4S8X-MX supports up to 2GB of RAM. Maximizing your system memory will allow your Asus Motherboards to operate as fast as possible and offer the most productive environment.
RAM modules must be installed in special locations on the motherboard called Sockets. These memory sockets are what hold the RAM module in place and can range from 1 to 16 or more. Banks consist of a group of 1 or more sockets. A system can have 1 or more of these banks of sockets. If a system has more than 1 socket in a bank, a Kit must be purchased for that bank. A kit is simply more than one, usually 2 or 4, like RAM modules. All sockets in a bank must be filled, and for such systems we sell memory in a kit. Typically you will see 2x512MB or 2x256MB signifying you are purchasing 2 units of 512MB RAM modules or 2 units of 256MB RAM modules, respectively.
The Asus Asus Motherboards P4S8X-MX has 1 bank(s) which have 2 socket(s) in each bank for a total of 2 memory socket(s). This means the Asus Motherboards P4S8X-MX can support up to 2 individual RAM modules.
We recommend you purchase the largest capacity RAM module each time you purchase memory. The reason for this is if you decide to upgrade again later and all your memory sockets are filled, you will not need to discard the already installed lower capacity memory.
Below is a visual representation of the memory bank(s) and socket(s) configuration for the Asus Asus Motherboards P4S8X-MX.

Gateway desktop fx 7026 memory issue, has 4 slots came with( 2 )2 gb sticks = 4 gigs it came with. when i add 2 extra gig it doesnt recognize.

the specs i read says 8 gig is the max. here is what it says for RAM
  • Installed Size 4.0 GB / 8.0 GB (max)
  • Technology DDR2 SDRAM
  • Memory Speed 667.0 MHz
  • Form Factor DIMM 240-pin
  • Features Dual channel memory architecture
  • Configuration Features 2 x 2 GB

check to make sure you have added the right type of memory. also look at your user manual. it should tell you where and how to place the added sticks. sometimes they have to be added in pairs or have to be in specific slots. also if you dont have the manual it is on the gateway site. you should type in your model and serial number and get all the info you need.

We purchased a hp touchsmart 600 with 4 gb of ram and ordered an additional 4 gb for a total of 8 gb of ram. We got (2) 2 gig but there are only slots for 2 memory sticks. We sent them back and now we have...

First find out if 4Gb sticks of the right type are available for your machine, and that the machine supports that much RAM. Then make sure you carefully order 2 x 4Gb sticks.

Acer Aspire 9410 Won't work with two memory slots filled

As you mentioned that you want to use Maximum memory that is supported by 9410, I would like to tell you that you have 32 bit processor in your notebook as its not always advisable to use 4 GB RAM with 32 bit processor as we have seen lots of compatibility issues.Infact in 32 bit processor windows will typically report only 3.2 GB due to a limitation of windows itself.

No display after upgrading RAM

Are you saying that there are only 2 slots for ram or 4, if 4 then you may have a dual channel lap top, in which case you need all of the ram to match, they all have to be the same exact cant mix and match, also is the bios recent, it sounds like you may need a bios flash if the laptop isn't recent.And there may be a limitation on the amount of ram it takes, I just setup a brand new acer and it only two gig max, see if they offer a bios update
