xw4600 ram upgrade (16GB) issues

[ Edited ]

I installed Win7 64-bit on an xw4600 (p/n FL828UT#ABA) for an engineer at work and the 4GB that came with it works fine.  I installed 16GB of ECC unbuffered ram of the same speed and got nothing but 5 beeps.  I tried each module in slot 1 (just one module) and got the same result.  Two modules in slots 1 and 3, same result.  Same speed, same error checking, same unbuffered, same voltage...

 

HP's quick specs say this model supports up to 16GB of DDR2-667 or DDR2-800 ECC unbuffered memory (pg 11):
http://h18000.www1.hp.com/products/quickspecs/12792_na/12792_na.PDF

 

Part number of the (4) 1GB modules that work in the pc (looks like Hynix is the manufacturer):

444908-051

 

Avant is the manufacturer of the ram I tried:
http://www.avanttechnology.com/DDR2_UDIMM/DDR2

Avant Part number:
AVF7251U64E6800F2

I took it back to the shop I bought it from and they said that I may need to try DDR2-667 instead of 800.  It's a special order though and 16GB of this type is nearly $500.

It looks like Axiom made the part numbers listed in another link I found on this forum regarding xw4600 ram compatibility issues, but the 4GB module I would be looking for (VH933AA) is discontinued.  Any suggestions will be appreciated.

Re: xw4600 ram upgrade (16GB) issues

Hi,

I checked the QuickSpecs for xw4600 and it only has support for 16GB (4x4GB) DDR2-800 ECC RAM. I didn't see the DDR2 667 support..

 

Thx

Re: xw4600 ram upgrade (16GB) issues

I'd like to clarify that PC2-5300 DDR2-667 DIMMs (ECC Unbuffered) is supported in xw4600 system. However the maximum size was 2GB for this speed.

Re: xw4600 ram upgrade (16GB) issues

Only supporting a 16gb at a higher speed seems, well, crazy? :)  Has anyone ever tried putting 16GB of non-ecc memory into these?

Re: xw4600 ram upgrade (16GB) issues

I was able to get the computer up to 8GB, but not 16GB.  I didn't try non-ecc ram.  I'm not sure what the issue is, but by the time the user requires more ram, I will have replaced the pc.  Very frustrating since he's an engineer and a friend of mine... I really wanted to max out his ram.  He had a few studies of SolidWorks with charts that showed a significant increase in performance when upgrading from 4GB to 8GB, a smaller increase from 8 to 12 and a negligible increase from 12 to 16, so I felt a little better.  I don't like leaving something unresolved, but there are too many other fires to put out (as usual).

Re: xw4600 ram upgrade (16GB) issues

Has anyone got any ideas on this issue please?

I am experiencing exactly the same issues.  Whether I insert 1 4GB stick or 2 or 4 4GB sticks all I get is 5 beeps from POST.  I don't get anything on display.

 

I am using VH933AA-HY (Hypertec equivalent), which is 4GB DDR2 ECC PC2-6400 unbuffered.

I have upgraded the BIOS to latest version already also.

 

Any help appreciated....

Thanks

Shaun

Re: xw4600 ram upgrade (16GB) issues

I just got one of these xw4600 systems.  I trust crucial.com more than any other for my RAM needs.

 

The top upgrade it shows is for 4GB kit (2GBx2), 240-pin DIMM, DDR2 PC2-5300 memory module.

Two of these kits will max it out at 8GB.

Re: xw4600 ram upgrade (16GB) issues

How many of 2GB modules do you have? Also please tell us part number of RAM.
