Corsair PC2700 XMS: 2 sticks not recognized.


Ramprobs

Recommended Posts

Specs: 2.1 Ghz intel, OEM motherboard, Audigy platinum PCI card, 2 RAM slots.

 

 

Ok, so I decided to update my RAM to 1 gig. I orginally had 256 XXXXXXXXX PC2700 so I decided to buy some quality like Corsair XMS PC2700.

 

Now I have put one stick in and it works fine, infact I am typing this with 480 Meg of memory. Windows boots up normally etc. As soon as I put both sticks in it loads the Window logo then black screen and nothing. Do you have any ideas why?

 

I checked my Mo-Bo with Sis Software Sandra and is says "maximum installable memory 4GB" so Im a bit confused as to why 2 don't work. It should support 1Gig right?

 

EDIT: is it something to do with voltage? The old Kings ram was 2.5V I think the Corsair is 5.1v? Im probably wrong....

 

I don't know what to do guys, I hope some of you can help out, meanwhile thanks for reading.

Where are you getting the 480Mb from?

The old Kings ram was 2.5V I think the Corsair is 5.1v? Im probably wrong....

Yes, Corsair RAM is only warranted up to 2.9 volts.

 

Are you mixing the Corsair RAM with the other RAM?

Forgot to tell you I have Windows XP.

 

I am not mixing the two sticks. I have installed two of EXACTLY the same sticks of Corsair PC2700 XMS and it shows a black screen past the Windows XP logo.

 

But funnily enough, putting just 1 stick of Corsair (512Meg) in and the system runs fine. Wtf?

Can you tell me the exact model# of your memory module and please tell me if you purchased that module as a pair or set; also what is the make and model of MB you have along with the CPU speed and its FSB as well? In addition, please tell me if you have the latest BIOS installed on your system and what BIOS settings you have set for both CPU and memory and any performance settings that you may have set?

Model:

 

CORSAIR XMS 512Mb DDR PC2700

 

The two sticks are exactly the same but were purchased separately, two separate purchases because they didnt have 1 stick of 1 Gigabyte.

 

My motherboard is OEM. It has 4 PCI slots, 1 AGP, 2 RAM slots. The CPU is a Intel Celeron 2.0 Ghz.

 

The BIOS were as I bought it. I bought the PC in 2003. I'm afraid I don't know if I have the latest BIOS and I have never tried to change anything because I don't know what I am doing. I can definitely find out with a little help, I apologise for coming into the forums unprepared but I am not knowledgable to such an extent, I am only a musician.

 

Let me know how to find out about BIOS or other things, I will post here anything which needs to be known.

Please set the following BIOS settings, but before making the necessary changes to make sure that you have the latest BIOS installed for your system board;

CPU CLOCK --------------------- 100

DRAM FREQ --------------------- 133

PCI LATENCY TIMER ------------- 32

DRAM TIMING CONTROL ---------- Manual

RAS Precharge Time: 3T

RAS Active Time: 6T

RAS to CAS Delay: 3T

CAS LATENCY: 2.5T

DRAM Addr CMD Rate: 1T

DRAM Voltage: 2.7/2.75 volts

AGP Voltage: Default *unless you have ATI (9200 or 9600) or NVIDIA (5200 or 5700) then 1.6 Volts suggested!*

All other settings are motherboards defaults

Then please test them one at a time with http://www.memtest.org and let’s make sure it's not some other issue! I would run the test for at least 2-3 passes to be sure!

thanks so much for the answer RAMGUY. I am on the case (the pc one).

 

I just found out you need to pay to upgrade your BIOS? What an absolute rip-off isn't there a way of just downloading the upgrades?

 

will let you know how I get on but first I'd like to know whether I can just download latest BIOS without paying.
