Is there a product recall on the small form factor AMD Radeon HD 6450 (Dell part # 6XMMP)? We are seeing quite a few fail that use the radiator heat sink. The card fails when the heat sink expands and distorts the circuit card causing a short circuit in the PCI-Express slot. Half of the failures have damaged the motherboard.
That certainly looks like a manufacturing Defect. The heatsink fins look different and thicker than the ones on the unit I have.
There is no recall. We have been using that video card on four systems (Optiplex 390/790/990/3010) for awhile now. I cannot find any record of a systemic failure. Were all of your systems purchased on the same batch order? The serial number (CN06XMMP744311AN03C0) you provided states that the video cards were manufactured on October 23, 2011. The Optiplex 390/790/990 were released for sale in 2011. The Optiplex 3010 in 2012. All you can do is have Dell Technical Support exchange the defective video cards using each systems service tag number.
Bill, though no recall was made on the graphics card that you have referred to using in four systems has two versions I know of and Dell uses two different part numbers in the System configuration, Components list for the Service Tag # build sheet. So though they are both AMD Radeon HD 6450 1Gig Graphics cards, the version change was critical enough for AMD to assign different part numbers (CN) to them.
Dell uses two part numbers; '6XMMP' and 'M0KV6' for the AMD Radeon HD 6450 1Gig graphics card.
What are the 3-4 groups the date? The 5th group being the production design part version?
If all four systems use the same small form factor style cards then there will be some form of Engineering/Tech notice at the manufacturers (AMD/ATI) level identifying the higher then normal failure rate of this model to initiate an engineering change to the production design.
This is the information I seek.
Since AMD is ISO9001 certified this eng/tech notice exists and it would be based on quality assurance feedback or warranty returns from system integrators like Dell. Even if it was a particular supplier's error in building the vapour chamber to AMD specification and it was a small batch problem, it was enough for AMD to change the version and start using cooling fans for improved product reliability. My concern is how many of the vapour chamber version (Dell part # 6XMMP) we have in the couple of thousand OP 990s' and the cost the increased failures will bring to our organization when the warranty expires.
6XMMP = OEM AMD Radeon HD6450, OPGA8, 1GB, Low Profile, Optiplex 390/790/990/3010
CN = China
0 = Filler
6XMMP = Dell part number
14431 = OEM factory ID (confidential)
1AN = Date 10/23/2011
03C0 = OEM manufacturer code (confidential)
A01 = Revision
M0KV6 = OEM AMD Radeon HD6450, OPGA8 v2, 1GB, Low Profile, Optiplex 390/790/990
CN = China
0 = Filler
M0KV6 = Dell part number
74431 = OEM factory ID (confidential)
25N = 5/23/2012
00LP = OEM manufacturer code (confidential)
A00 = Revision
then there will be some form of Engineering/Tech notice at the manufacturers (AMD/ATI) level identifying the higher then normal failure rate of this model to initiate an engineering change to the production design.
* We never receive this data. Even if we did, it would be Dell and OEM confidential data.
I have two on the job here. Exact same symptoms, same problem. I support 80 of these systems in my work environment.
CN-0K6HDT-74431-18R-01TY-A01 (If I am accurately reading the tiny characters on the sticker).
Warranty expired on these systems precisely a month ago.
