Since I do weekly backups and the data is mostly static, 10 was definitely the choice.I went with the same 2Tb WD Red drives as you did. From what I saw, Raid 6 was sightly more tolerant to double drive failures, but 10 was significantly faster. I determined that 10 was a better fit for me. Nor were the front usb/firewireports.įor Raid, look at Raid 6 and Raid 10 to determine which is the best fit for you. I leave my machine on 24/7 with a ups so the power button was not an issue. On every bootup, I would get an error message about it. I always MEAN to do that sort of thing but once you get the bit between your teeth its hard to remember to take nice photos.īesides power, the biggest thing I noticed without the correct cables was the thermal monitor.

I intend to document my upgrade so I'll post back when its done and get some photos up etc so anyone else planning it can have a look. Glad to hear your machine is running well, Dell has a bad rep for consumer level machines but the Precision range are spot on.

I know 2x 150W is at max, but I do give my machines some hard use and Id be somewhat aggravated if it shit the bed after a while under full load. 300W on CPUs alone is quite a lot, I've had whole PCs that havent used anywhere near that. I'll start with one, but it might be CPU power consumption that forces a PSU upgrade in the end. Suspect It'll come in useful as I intend to get a pair of Xeon X5492 3.4GHz 1600MHz. Sees all the different fan controller channels and heat sensors and lets you set up thermal profiles with variable hysteresis, fan speeds etc. Runs RAID6 very nicely.ĭont know if you know but Speedfan works on the 690 perfectly, so cant see why it wouldnt work on the T7400. I think its similarish to a Perc 6, should run SAS drives but I've just hung some SATA WD RE4 drives on it. My RAID card is a HP Smart Array P400, had an appaling rep at first but as long as you have the battery backed 512Mb module along with the (absolutely vital) latest firmware it flies. Although I suppose they might if I went low budget and completely filled them with 1Gb sticks. I find it hard to believe the risers will add more than another dozen or 2 watts to the total. Power wise the DVD drive is disconnected, HDDs are spun down most of the time and my boot drive is a ~240Gb Revodrive Pci-e SSD and Im only using 1 video card (GTX660 2Gb or Quadro FX4600, depends on workload) so I shouldnt be putting too much strain on the PSU. As it uses 12V and Gnd I should be able to hack up an adapter cable from the HDD supply. The connectors look close enough to Molex KK type, luckily I have a bag of the shells & pins - and the right crimping tool.

Luckily the 690 manual has the pinout for the memory risers so I can make up the cable when I get some risers. It was listed in such a way that searching for the expected terms missed it, complete fluke I saw it. I've just bought a T7400 front panel ribbon cable for almost nothing so hopefully that'll sort that issue out. Very pleasing to hear that the mobo power arrangements are the same, Dell are funny about pinouts and I wouldnt put it past them to change them even between minor revisions like 690 -> T7400. Do I even need to worry about it, are there other sensors that will trigger the fans to throttle up when needed? The MB took some modifications in the io area. To my question, will the front panel from a T7400 mount to a 690 chassis. I have not really tried to push it hard until I either get a sensor on it or am sure that the fans will throttle up without the sensor. When the system first boots, there is a brief warning about the thermal sensor missing. Where I am concerned is about the thermal connector. I just don't have front usb or a working power button, both of which I can live without. When the cable it plugged in, the fans in the system rev up to full throttle and nothing works. I tried a small drill bit on the ribbon cable to open the pin so it would physically fit. It also does not have a connector for the thermal. The new motherboard has a different pinout for the front panel. The 690 uses a ribbon cable and a 2 wire thermal connector. The one issue I ran into was with the front panel connector.

I was able to get it to boot up my existing install of ESXi 5.5 with a few minimal tweaks in the bios. I was able to move from a single 5355 to dual 5430's for under $50. I already had some extra Xeon e5430's laying around and they both use the same memory. So after reading that it was possible to upgrade the 690 chassis to a T7400 mb, I took the plunge and bought a new mb.
