Dimm Riser card ?

Hello,
I need to get a new dimm riser card as one of mine seems to be faulty, can these be bought from apple?
I don't see anything on the apple online store, if i phone them could i order one? or go into town to the apple store & buy one? if not where is a recomended place to go please?
The problem with the card is:
Dimm riser A / Dimm 3
Dimm riser A / Dimm 4
These 2 don't show as having any memory in them, i've changed memory to check it wasn't the memory.
Any help is very much appreciated please.

Hi, thanks for the quick reply, i should have mentioned i live in the UK. Those 2 site are in America, does that matter or should i find a site in uk?
In the powerbook medic site it says it not in stock. In the dvwarehouse site there's 2 links:
Apple memory riser card for mac pro first generation 922-7695
Apple memory riser card for mac pro early 2008 820-2178 922-8492
which is right for my mac please? (sorry i'm not very expeienced at this stuff)
some info from my mac:
Model Name:          Mac Pro
Model Identifier:          MacPro3,1
Processor Name:          Quad-Core Intel Xeon
Processor Speed:          3 GHz

RAM or Riser Card

I have a Mac Pro 1,1 and have been experiencing some RAM problems. First, I had RAM sticks fail on the entire top riser card. I replaced all of it and have been fine up until now. Now, when I start up my machine, one pair of 2 GB sticks will register as 1 GB each. But if I restart, this sometimes goes away and the full capacity comes back to 2 GB each. How can I figure out if this is a Riser Card problem or a RAM issue? It's hard to believe the new RAM I just recieved a few months ago already went bad!
Thanks.

Sometimes new RAM instantly fails.
Sometimes your computer case is too warm
Sometimes running SmcFancontrol 2.3+ @ 900 rpm as new default works to get more air flow
These are you are sure Mac Pro certified DIMMs.
Contact the seller.
Don't continue to use RAM that is 'sometimes' that is not ever normal (I have seen people with EVGA SR2 though that have RAM not show up but they are also playing with voltage and timing and experimenting more).

Bad Riser Card = send to shop?

Hey everyone,
I'm the (otherwise very happy) owner of a 2007 8-Core Mac Pro getting ECC errors from a specific DIMM on what I believe to be a bad riser card. I gave away the stock 1 GB RAM and am using 4x2GB sticks from TransIntl.com and installed on my machine since Day 1
When I spoke to someone at AppleCare, they told me that I had to send my machine in to an Apple Store (or Apple Authorized Service Center) since the riser card, at least according to the info she had in front of her, isn't a user-replaceable part. This was tough for me to believe, but I didn't want to argue unnecessarily.
So my question is: does Apple really not send replacement riser cards out to users? On a PowerMac G4 years ago, I was sent a replacement SuperDrive when mine went bad. I'd consider a riser card - especially on the beautifully designed Mac Pros - to be eminently easier to replace, so this doesn't make sense to me.
Since this is the first time I'm posting about this issue here on Apple Discussions: yes, I'm fairly certain my riser card is bad. I've done all the tests for this - swapped the RAM modules, swapped the riser cards between slots - and the same DIMM on the same card reports ECC errors after awhile (my machine is on 24/7).
Curious to hear experiences or opinions...

Once you replace the RAM yourself, you expose yourself to the possibility that the warranty won't be honored if you damage something in the process. Read the RAM installation instructions for your model in the Do-It-Yourself page of Apple's support website. All the disclaimers are there. If you sold the DIMM, unfortunately you have further eliminated any chance of discovering if the problem was the Transintl module or the riser card, unless you try yet another RAM card that is new from a renowned vendor. You are better off letting an authorized service center do the installation, because that way, they can document it for Apple that it was done by them. Regardless of what Apple says here, this is a user to user forum, and we can't really discuss policy. You'd best just take it up with Apple if you find two highly renouned vendors aren't able to give you a working RAM card in your machine*:

And in the future, never sell elements you replace yourself until you are certain the replacement part works.

There are extra cables there to supply power, You will need to break out a solder kit and hook them up to a molex connector (which is a fairly easy to do).

K8D Master-FT PCI / Riser Card Help

Ok, I have just taking my first venture into the true server class motherboard. We chose the K8D Master-FT w/ a pair of opteron 240's. I have ran into a few issues that I just can't seem to find any answers on.
1. We used a third-party case which didn't come with a riser card. Do I need a PCI-X riser card or can I still use a 32bit riser. Also once I have the correct riser card can I still use 32bit PCI devices on the riser?
2. Next if I only want to use one slot can I just use the PCI-X slot on the motherboard without a riser? If so can I use a 32bit PCI card?
Thanks a bunch in advance.

Ok. Here are the details. We get the system board in and we grab a rack case with the correct form factor. Problem is the case didn't come with a riser card. None the less we where under the same impression that we could stick a PCI or PCI-X card in the slot. We only have a single card (RAID controller) which we intend to use. When we insert the PCI (32-bit) raid card in the PCI-X slot the system won't boot. We even tried inserting the card every which way we could in the slot thinking maybe we had inserted it wrong. Still no luck. Should our raid controller be 64 bit? Also we did have some riser cards that came with some ATX form factor rack cases, but when inserted into the PCI-X slot, the card slots face oddly up the motherboard towards the I/O panel. Thanks.

K7N420 pro MSI 6952 TV-Out Riser Card troubles

just wondering if anyone has gotten the MSI 6952 TV-Out Riser Card to go with their K7N420 pro motherboard and if so how do you get it to work as ive tried for months on end and i still have many failed attempts at getting it to function

It is your drivers. You need to get the 29.XX series of detonator drivers and use those to get tv-out to function.
I had a K7N420 and a tv-out card... long dead, exploded caps. I recall that the last version of the detonators that worked for sure was the 29.20s. I experience the same difficulty with my geforce3 Ti500 and the new drivers... no tv-out signal as the drivers cannot seem to detect the presence of a tv on the other end of the svideo cable.
Try it out and see if it works

Help hooking up MSI 6 channel audio-output riser card and DTT2500

Hi guys,
I'm having trouble here. I originally had my SBLive hooked up to my DTT2500 speakers (yeah I know, overpriced POS) through a 2.5mm-->DIN(9pin) jack. The SBLive has a 2.5mm spdif out on it. Now I swapped to an Nforce board and I'm using the onboard MCP audio. I used the CNR riser card (picture below) thinking this would be an easy switch. But unfortunately things don't go that well for me. Turns out that the SPDIF on the Riser is an RCA spdif out, not 2.5mm. So, my question is, how do I hook up:
SPDIF RCA OUT----->2.5mm
.....or.................
SPDIF RCA OUT----->9pin Digital DIN
Any ideas??? The SPDIF is the bottom jack of the 3 in the picture below, right????

I'm gonna try this again while our friend here shows an illustration and I can elaborate. Sorry to crash this thread but I see an opportunity here, and someone else may benefit from it as well.
I too gave up and switched to the SB live becuase I like sound coming out of all 4 speakers of my Altec lansing 4.1 analog system.
1. Does this mean that I can switch back and use the jack on the CNR card for the rear speaker connector since I have only two plugs from my AL's.
2. Do I now have control over the 4 speakers or is it the same as before where you can only hear sound out of four speakers when it is encoded for it?
3. finally, (see illustration) the wire loop/connector that connects the CNR card to the MB, shows it is connected at the header behind the SPDIF Jack (it comes that way).
A. Do I need to leave it there or move it to the header behind one of the other jacks for ANALOG???? or will it work the way it is?
I tried bringing this up in the old forum in my early days but it seems it was overlooked. I moved on and got my SB LIVE...yeah I know, but I just can't do without 4 speaker sound, not just a mirror image for the rear.
I don't want to have to shell out another 200 beans for a new speaker system...yet
So does anyone have any experience relating to the questions I have asked? ?( ?( ?(

Audio Riser Card

Mac Pro 1,1 two different riser card.

When I got my Mac 1,1 Pro used, it only came with one riser card. Now I recently bought another riser card from ebay, but it is a different color (the original was light blue and the new one is indigo). Everything does work, but I was just wondering did apple use two different riser cards, because they are the same model and both were built in 2006 by Apple. Also this won't cause any optimization issue, Right? This maybe a small thing but hey, can't be too cautious. Anyway, Thanks For Your Help.

deal with reliable place like DVWarehouse which has 1,1 part number but $70
Apple Memory Riser card for Mac Pro First Generation 922-7695 - NEW - $78
there is another vendor that also carries parts and was about $40
Mac Pro Memory Riser

Muy DIMM riser A has 'disappeared'

Just bought 4 x 2GB modules, installed them on both risers, in the first two slots.Remaining slots are filled with 4 x 1 GBs.
Restarting, check 'About This Mac...' it reports 6 GB instead of 12 GB.
Using ASP, it reports that DIMM Riser A 'Empty' for every slot.
I've re-seated the riser, same thing. I noticed that the red LEDs flashed on both risers when I started up...so both are getting juice.
Anyone have any idea what's going on?
TIA,

I am having a similar problem with an 8-core mid-2007 Mac Pro. It boots fine with 2 x 2 GB of Transcend RAM in it in the correct positions in Riser A and Riser B but when I add 4 x 2 GB of Netlist RAM from OWC (which is RMA exchange for previous OWC RAM that did no work) it will only see one of each 2 GB pair in DIMM 1 and 2 slots in Riser A and B for a total of 4 GB.
By swapping round the working Transcend 2 x 2 and Apple 2 x 512 MB (shows as 5 GB), it seems like all the riser slots are working. And since this is replacement Netlist RAM for OWC RAM that showed similar RAM total problems, I am thinking it is something else going on. IT is odd that you found 4 x 2 in Riser A and 4 x 1 in Riser B gave the right total.
Any suggestions. I have tried all the usual PRAM resets and SM reset.

Please recommend a right-angled PCI-e 16x riser card/cable for a Media Live

The IGP in my Media Live is not running properly, or nVidia's drivers for it are just crap (more likely, I guess), so I need to fit a dedicated video card. The riser fitted for the supplied Hauppage WinTV card is for a PCI slot... I have Aero turned off, which ameliorates teh problem but some windows/applications still don't render properly.
I am having trouble finding a suitable riser card for a PCI-e 16x slot though. The main problem is that the 16x slot is not directly underneath the mounting points for the riser card, which means I need a riser with a flexible cable. Secondly it needs to be right angled and thirdly the slot needs to lie lower than the mounting holes. Most every riser card I've seen has the slot level with or above the mounting holes, however this would not work in the Media Live case.
In a pinch, I guess I could live with a PCI graphics card... but are there ANY modern PCI graphics cards????
So is there a recommended riser card I should use, or am I stuck?

CPU in and running fine. No issues so far, although I haven't run it under load yet.
My Titan heatsink was a tricky fit, the heatpipes are literally touching the RAM heatsinks (though not pressing against them) and the holes in the motherboard were on the large side. Installation instructions were ok but parts bags mislabled! And the supplied thermal paste was horrible... still, it really is a low profile heatsink and one rated to 130Ws - unlike just about every other one out there! The fan I fitted is a Scythe Gentle Typhoon 92mm unit and is really quiet! I hadn't realised just how noisy the original machine was, but with the Typhoon and the Silverstone PSU fitted it is genuinely quiet. Lastly, unlike the GT64 fitted before, it's fins go sideways, not front/backwards, and that means air coming off the heatsink will now go over the heatsink on the NB...
Speaking of which, I discovered the NB heatsink was rather loosely fitted. I'm going to score an aftermarket one with a bigger sink and *maybe* a fan and fit that soon. With proper thermal paste.
Lastly, since they were mentioned as a potential problem, I took a pic of what I think are the VRMs?
If I'm right, I can readily fit a heatsink to those if it would help.
With 8GBs of RAM and a 600GB Velociraptor coming, I am going to do a new windows build soon with 64bit Ultimate. After that, all I have to do is source a slot-load BR drive and the upgrades will be done. Modding the case will be another job...

Pci-X cards in mac pro via bridge/riser cards possible?

It's time to upgrade from my G5 to Intel. I have a legacy PCI audio card that will cost $900 to replace with the later PCIe version. Yet I see for $35-$55, there are PCIe riser/bridge cards that will permit, at least in some computers, attaching PCI-X cards to PCIe host slots: e.g. Intel ASR2500FHR, Anantech AIMB-R430P-03A2E, StarTech PEX1PCI1, ...
Anyone know if it's possible to use such an adapter in a Mac Pro: enough space, able to get power to expansion slot bay (perhaps from 2nd optical drive power connector?), compatible with Mac OS X 6.3?
TIA.

If it would work, you would have to cut into the back of the Mac Pro, because the metal on the back would not line up with the end of the PCI-X card.
You could go for something like this: http://www.magma.com/6slot.asp (which does support Mac OSX) but I'd think that would cost considerably more than just buying the new audio card.
I think your best option is to just buy the new card, you could sell the old card to make up some of the cost of the newer one. Are you sure you need an audio card that expensive? Aren't there other/newer options on the market by now that are less expensive, for the same set of features?

Do i have a bad batch of ram or a bad riser card?

I recently took my mac pro 3.1 up to 16 gigs of ram in 8 2gb dimms. I had the dimm in riser b slot go bad and I replaced it. It took a few days to get a new dimm so took the dimm out slot 4 and put it into slot 2 and removed dimm 3 as well so that i had 12 gb to work with. When I put the replace ment dimm and the dimm out of slot 3 back in the dimm in slot 2 gave me a red LED. I moved it to slot 4 to try reseeting it but it still shows bad in slot 4. do you think I got a bad batch of ram or that my riser is killing the ram that I have? I dont want to have to keep replacing the tam if my mac is killing the ram.

I have a hard time following
DIMMs are always treated in pairs, and returned as such, no one replaces a single DIMM.
8 x 2GB with 4 on each Riser is fine.
You should have returned both A3 and A4 (you don't metion which Riser so I'll just use A).
There should be method to madness.
Try one set at a time. Or half. Or all on one Riser
Try swapping Riser A and B.
Apple Hardware Test is of help with Risers and 'mechanical' errors. To test software based errors.
Having a DIMM or set show as HALF their rated capacity is also a common problem with FBDIMMs, which should always be kept cool as possible and monitored, including increase of the system fans by 300-400 rpm.
As I said, Crucial, MacSales, Ramjet, Trans, they all want you to return the matching sets.
I don't think your Risers are killing your RAM. but maybe choice and handling and vendor.

Non responsive MacPro won't boot

I currently have a major dilamma. My 5 year old Mac Pro as from yesterday, won't boot up. Instead I get a pink and white pattern on the screen followed by the spnning wheel. There seems to be no way to access any of the other internal drives on the Mac as I have cloned the original HD for this specific reason.
Any advice would be most appreciated, as I sincerely hope this doesn't mean buying a new Mac.
Thanks in advance.
Justin

System Profile or what you remember.
9GB tells me 2006/7 with FBDIMMs and a 2 x 512MB set
An older GPU that likely needs to be replaced. X1900 or OEM 7300GT or 8800GT
Pull all the drives out.
Shutdown and unplug everything. Press power on button for 10 seconds then connect just kb/mouse display and power.
Zap PRAM/NVRAM
Now connect your cloned drive.
Oh, and inspect the graphic card for make/model and dust.
Inspect the DIMM Riser cards.
Try with just one set of newest RAM in slot A1 and A2
Consider new FBDIMM set $25 from Amazon, and a new ATI 5770 for $250 from Apple.
Might need a new system boot drive. Try Samsung 840 EVO 120GB $99.
2x2GB FBDIMM DDR2 667MHz @ $25
http://www.amazon.com/BUFFERED-PC2-5300-FB-DIMM-APPLE-Memory/dp/B002ORUUAC/
SSD: Samsung 840 EVO 250GB $171

No you don't need a new Mac Pro.

Apple Raid Card panic on Mac Pro Early 2008 after installing SSD as an enhanced JBOD.

I recently installed a SSD drive in my Mac Pro to replace an aging, original boot drive. I have an Apple raid card with 3 other hds attached - all in an enhanced JBOD configuration. After installing the SSD from OWC (3G Electra SATA II Compatible) everything appeared to work fine. But after 36 hours I received a apple raid card kernel panic alert. See below for diagnostic crash log. OWC support says that their drive should work fine - now I am not so sure. Anyone out there with suggestions/solutions is most welcomed.

RE: Mac Pro Replacement Graphics cards
1) Apple brand cards,
2) "sold in the Apple store" cards, and
3) "Mac Edition" cards ...
... show all the screens, including Boot up screens, Safe Mode, Installer, Recovery, debug screens, and Alt/Option boot screens. At this writing, these choices include:
1) Apple brand cards:
• Apple-firmware 5770, about US$250** works near full speed in every model Mac Pro, Drivers in 10.6.5
• Apple-firmware 5870, about US$450
2) "sold in the Apple store" cards
• NVIDIA Quadro 4000, about US$1200
• NVIDIA Quadro 5000, about US$2500
3) "Mac Edition" cards -- REQUIRE 10.8.3 or later:
• SAPPHIRE HD 7950 3GB GDDR5 MAC Edition, about US$480** Vendor recommends Mac Pro 4,1
• EVGA GTX 680 Mac Edition, about US$600
The cards above require no more than the provided two 6-pin aux power connectors provided in the Mac Pro through 2012 model. Aux cables may not be provided for third-party cards, but are readily available.
If you are Meet ALL of these:
• running 10.8.3 or later AND
• don't care about "no boot screens" etc AND
• can re-wire or otherwise "work out" the power cabling, THEN:
You can use many more cards, even most "PC-only cards"

Dimm Riser card ?
