ANY XPS M1530 owners with 800mhz DDR2 memory, please look in***

Hey everybody, I have a xps M1530 notebook with the corsair 8gb ddr2 kit.

I'm having some errors come up with memtest but on my other laptop with the same memory it can't find anything.

My guess might be the chipset, which only supports 533 and 667mhz memory. The memory is recognized in windows 7 x64 properly but I am trying to find out why memtest is giving me errors. This is a replacement memory set I recieved today.


If anybody has the following, PLEASE PM and/or post here.

I need a few people with the following requirements:

-Dell XPS M1530
6gb+ DDR2 800mhz memory installed


What I'm trying to find out is, if the laptop downclocks the 800mhz memory to 667mhz, is that causing me the memtest errors?


What am I asking for help with? Anybody that contacts me with the same laptop and 6gig+ 800mhz memory, I would ask if they could run a memtest86 memory test on their laptop to see if the 800mhz will give them any error or not.


Thank you

 

Ttttt Tttt

 

It will downclock it. But I don't think that would be cause for errors. It is possible that it is, or it is also possible that the memory controller or something else is responsible for the errors.

 

I know it downclocks, it shows it in the bios as 667mhz and reads 8gb in the bios itself.

memtext86 gave errors and the Dell Diagnostic reported error 2000-0123 integrity test failed, yet I can load into windows perfectly, I ran prime95 over night via blended test and everything passed.

My quess is this....not many people have done the memtest86 test with 800mhz 8gig ram on the m1530 so its hard to find documentation on it and it might just be an overall issue somehow with the bios update and the type of ram.

OR, the memory is 50% compatible with the system. Corsair only recommends 4gb on the M1530 on their site, so it could be that the ram wasn't made to be compatible with the system, it it somehow is sorta.

I'm waiting for G.Skill 8gb ddr2 667mhz memory to arrive so I can do the same tests and find out.

If the G.Skill 8gb sticks doe the same error, I would say it is an issue with the bios update and somehow with the chipset.


Here is the chipset information for the dell:



Here is the chipset information for the Sony laptop I tested the 8GB memory in and it passed the full memtest86 tests fine.

 

XPS M1530 is Santa Rosa, and it does not support DDR2-800 RAM, only 667. When PM/GM965 came out, 4 GB SODIMM modules were not out yet, so Intel never bothered to update their information. Only certain laptops AND their BIOS will allow for 6-8 GB RAM that have the PM/GM965 chipset. Unfortunately case in point my Vostro 1500 housing the 965PM chipset only will do 4 GB RAM. It will not POST with 6 or 8 GB.

 

Hmmm see thats interesting and I can imagine this being the issue with the chipset. As I mentioned, my M1530 loads up fine into windows, is recognized, does NOT crash, works great with VMware...but its when I do the memtest85 and dell diagnostic it finds errors. But the sony, with a different and more compatible chipset with the memory has no problems at all.

Very weird issue, I'll have to see what the G.Skill 8GB 667mhz memory will do.
