When I put back the original 256MB it came with, everything works. I thought as long as I match the spec it would work... but I guess wrong.

So, what type of DIMM do i have to get to upgrade the cache? TIA for any hints..
Ok, i should correct myself...

the DIMM i tried was a 512MB PC3200 400Mhz ECC Registered single rank DIMM. That didn't work.

Today, I received my order of a 512MB PC4200 533Mhz non-buffered,non-registered, ECC single rank DIMM. This was based on a post in this thread (took a while to search through this very long thread). Unfortunately, that too didn't work!

So, what gives? Anyone have any specific DIMM part number they can share that has been verified to work? Is the upgrade to 512MB cache limited to specific firmware? (I'm on the latest Dell firmware)

Help....???

Hi,
Need some help. I just installed a Perc 5/i with a BBU on my XPS720. I am running vista x86. I am running 7.0.1-0066 ver of the firmware. I am doing RAID 5 with four 1 TB drives. I created the array, initialized it and then used Vistas disk manager to format and create a GPT partition. I see the 2.8~3.0 TB drive show up. I can even add data to it but if I try to access mp3's or any of my backed up movies I do not get sound.

I am running LSI Mega Raid software and it keeps giving me an error "Drive is not certified" for all four drives. I must be doing something wrong. Does anyone have any suggestions?
post #2424 of 7150
The drive is not certified message is nothing to worry about and is a common occurrence with non-SAS drives.

Can you get sound when the movie/mp3 is on your main HD?

what firmware are you running? I'm wondering if my issue is firmware related... because the specs of the Kingston DIMM you refer to is exactly the same as the first PC3200R DIMM I tried...

OK. I think I've found out a few things about compatible DIMMs...

First off, Manyak has a post about using unbuffered/unregistered ECC DIMM @533Mhz, which seems to be totally wrong. I wish Manyak or a moderator would correct the misinformation as at least another member here and myself have ordered the wrong DIMM based on that information.

The correct DIMM type seems to be DDR2 PC3200 400Mhz ECC Registered single rank. However, I have a few of these DIMMs sitting around and none of them worked. I then looked into the specs of the Kingston DIMM suggested above and noticed a difference between that and the DIMMs I have: the Kingston (newegg P/N: N82E16820134287) is 1Rx8 while the DIMMs i have are 1Rx4. I suspect the memory controller on the PERC 5/I isn't capable of addressing both sides of the DIMM to get a 72bit data path on the 1Rx4. This is also backed by the fact that the original DIMM that does work is also a single sided DIMM with I think is 5 chips for a 1Rx16.

So, I *think* the correct memory type for the PERC 5/I is:

PC3200 400Mhz DDR-2 ECC Registered Single Rank CL3 1.8V *single sided* (which means at least 1Rx8 or 1Rx16, but i think x8 is cheaper)

Maybe this information can be included in the original/first post? Would be useful as searching through 240+ page thread isn't always practical...

i honestly don't know for sure, but it says power edge expandable raid card when it boots so i'm thinking it's the dell firmware.

So, running a bit with this theory about the PERC5 memory controller, I looked for 1GB DIMMs that meet the same specifications and found:

Kingston KVR400D2S8R3/1G http://www.valueram.com/datasheets/KVR400D2S8R3_1G.pdf

Looks like it uses 128M chips on a single sided 9 chip arrangement. It *might* just work... *IF* it does work, the only issue might be that the BBU capacity will not last as long so you'll have bring power back to the system sooner after a power loss crash; before the BBU runs out of juice and the data in the cache gets wiped out.

the correct type of memory is described in Dellâ„¢ PowerEdgeâ„¢ Expandable RAID Controller 5/i and 5/E User's Guide

NOTICE: PERC 5 cards support DELL-qualified 256-MB DDRII 400MHz ECC-registered DIMMs with x16 DRAM components. Installing unsupported memory causes the system to hang at POST.

also thread from 2cpu.com is very usefull:

You have to buy x8 or x16 Memory Modules.
x8 = 9 Chips (1 ECC)
x16 = 5 Chips (1 ECC)


I'm using SAMSUNG M393T6553CZ3-CCC - 512MB 1Rx8 PC2-3200R-333-12-A3

Wow... a week of google searching never turned up any of those pages! Thanks for pointing that out and i guess it confirms what I suspected. The 2cpu.com thread also indicates even with the single sided DIMM, 1GB will only show up as 512MB.

but 1GB limit is by firmware/chipset - not by memory module
I've read in INTEL specification - yes - they also have similar card based on same LSI model like PERC 5/i - there was info about 1GB cache - but there was also info that there is no 1GB memory modules available to buy ...
