PC3200 Ram reading as PC2600


Recommended Posts



I just installed a second stick of 512 meg PC3200 Value Select Corsair Ram. During the boot sequence bios states that the mem speed is 333m, it used to read 400. I ran Everest to benchmark the ram and it is stating that I have PC2600 Ram installed. My mobo is an Albatron K8X800 Pro (5 PCI, 1 AGP, 3 DDR DIMM, Audio, LAN). My computer came with 512 megs of the same exact memory. I am not sure how to correct this. Any help or suggestions would be greatly appreciated.

Thank you so much for your assistance. I am at work, but I will get that information to you when I get home. I can report that the green sticker on both ram sticks say VS512400. I should also mention that my computer is reporting that I have 2048 megs of ram instead of the actual 1024. I ran a scan on pcpitstop.com and here is what was reported:


"Memory Configuration



RAM installed 2048 MB

Windows RAM 1024 MB

Total RAM slots 4

Available RAM slots 2

Max RAM module size 32 MB

Memory Type 1024+1024+0+0;DIMM,Unknown,;T16

Speed Rating 6832 MB/s (102% of 812 similar)


Speed rating is measured in megabytes per second. The percentage indicates the performance of this system compared to systems in our database with a similar CPU and clock speed; the number of similar systems is also shown. For example, a score of 50% would indicate this system had half the performance of comparable systems; 200% would indicate twice the performance. A "normal" number is 100% plus or minus about 15%.

The System Management BIOS is reporting that there is 2048 MB of RAM, but Windows reports that 1024 MB is available. The most common reason for this discrepancy is that your system uses some system RAM for the video graphics card or BIOS functions. This case is common in highly-integrated PCs with video graphics built into the system board, and does not require any changes on your part.

There is a large discrepancy between the memory reported by the BIOS versus Windows. Often, this indicates a System Management BIOS (SMBIOS) problem and you may be able to fix it with a BIOS upgrade available from the vendor. SMBIOS results can be incorrect even if the power-on self test (POST) detects all of your installed RAM. For more insight into what your SMBIOS reports and why it can be wrong, download and run our SMBIOS reporting tools.”


I don’t know if this is related.


I have some computer knowledge, just enough to know that I shouldn’t be playing around in bios. I do not have an onboard graphics chip, my video card is a Chaintech 5900XT. I did note an immediate improvement when I booted up Half Life 2. Prior to installing the RAM I was a victim of the “stutter bug”. Thankfully this was cured by the addition of RAM. My wife plays The Sims 2 and it now runs much smoother as well. I would just like to get the best possible performance out of my comp. Thank you again for your assistance, it is very appreciated.

I am very appreciative of the offer for replacement, however, what piece of information leads you to believe the ram needs to be replaced? I am just curious. Also, I need the computer for day-to-day operations so replacement of both sticks would be difficult, unless we could stagger the replacements. The original stick of ram seems to work just fine, and honestly, the performance increase after the addition of the new ram is quite impressive. Have you ever run into a situation where the bios is stating that more than the actual amount of ram is installed?


Thank you again for your response, I commend you on your excellent customer service.

The modules being detected as 1.0 Gig modules would suggest either the modules SPD is not programed properly or there is some problem with your MB. To be sure its not the modules I am happy to just replace them. But if you can test them in another system that might help isolate the memory from your system.
