It should. I have an X10DRH-iT (no SAS), and BIOS 3.4a has IIO/IOU bifurcation settings. I haven't played around with it yet, so I'm not sure if all slots can simultaneously bifurcate to x4, but I'd assume most slots can.
Awesome thank you!It should. I have an X10DRH-iT (no SAS), and BIOS 3.4a has IIO/IOU bifurcation settings. I haven't played around with it yet, so I'm not sure if all slots can simultaneously bifurcate to x4, but I'd assume most slots can.
my 2 cents. X10DRH-CT is one specific board in the SM dual CPU X10 ATX based form factor.@Sean Ho , do you know if bifurcation is supported on the X10DRH-CT? If so, that may very well be the board I order.
Basically ready to start moving forward on this!
That's fine, I'm hopeful that it'll breakout into 4 x4 though. Either way I think the X10DRH-iT is the board I'm purchasing.Yes, the x16 is electrically x16. I see the bifurcation option in bios setup, but again I haven't actually tried it yet, though I have an ASUS hyper 4 m.2 card in another node.
Fair enough. RAM I'm starting with 4x 32GB sticks, hopefully getting more in the next 3 months.CPUs (and RAM) are the easiest components to upgrade, so if you like you can get 6c v3 chips for now and upgrade later. Or even run single processor to start with, forgoing a couple of the PCIe slots.
Thank you for catching this, I didn't even think about that.my 2 cents. X10DRH-CT is one specific board in the SM dual CPU X10 ATX based form factor.
The -CT has hardware raid (LSI 3108) which can't be flashed to IT mode (AFAIK). that seems incongruous with your stated and discussed OS platforms. Since you are bringing your own SAS card and I suspect 10Gbe card maybe looking at some others that don't have unnecessary hardware that will also add to the power load of your system might be in order?
Some of the PCIE lanes would be allocated to the onboard raid and whether those are mixed in with lanes on the slots or NOT - IDK without looking in the manual.
@Sean Ho 's specific board comes to mind since it is basically stripped of superfluous stuff.
also X10DRi boards too .
SM's site is pretty good at filtering stuff so you can pair down the results and find what you need under building blocks -> server boards
If you have the spare 4 pin molex I think you'll be fine. The connector is "old school" but also designed for pretty high loads (unlike splitting sata connectors).ok so I got all the parts and saw that I made an amazingly bad oversight.
This chassis originally came to me years ago, with a dual cpu motherboard in it.
However, it doesn't appear to have 2x 8pin connectors. I have 1x 8pin and 1x 4 pin.
Is something like this a bad idea? Or should I consider returning the board and getting a single cpu for now?
I don't know that I can get a new module that the power supplies slide into, having trouble finding that info (chassis is a chenbro rm31616 )
yeah, I have the spare molex. I agree, no daisy chaining splitters.If you have the spare 4 pin molex I think you'll be fine. The connector is "old school" but also designed for pretty high loads (unlike splitting sata connectors).
There are also dual 8 pin power splitters too if you can't pull the 4 pin molex over where you need it.
Those are not exactly high TDP cpu's and IIRC you said you weren't likely to stress the CPU too much.
Me personally I try very hard not to daisy chain splitters so my rule of thumb is one original molex drop off a cable, one splitter. If a cable has three molex drops on it and I'm not too power hungry I'm okay putting a splitter off each molex. sometimes though in small systems you find yourself needing more than a few splitters.
looks like it's finally time to learn how to a multimeter ha.Adapter cable should be fine; just use a multimeter to verify the pinout of the PSU cable. If your PSU has 6+2-pin PCIe power or a spare Molex power, you could also use adapter cables on those (again, double-check with multimeter).
there's max TDP intel ark says 90. there's the performance curve and idle. all good to know. please do report back on that!I'm going to look around online for power specs on these cpu's, not only for this but just because I'm curious.
I started labbing with two xeon x5670's, and those we definitely hungry cpu's. I'm interested to see how efficient this cpu is comparatively.
This.looks like it's finally time to learn how to a multimeter ha.
But TDP is a measure of heats generated in watts, right?there's max TDP intel ark says 90. there's the performance curve and idle. all good to know. please do report back on that!
This.
Using a multimeter is a handy thing to know / have. cheap ones < $15USD are good and provide basic functionality.
I still have an old radio shack needle multimeter somewhere!
editedJust edited my post.. I noted the wrong CPU. It's an e5-2620 v4, not the 2640 v4.
The not too distant past, at that.TDP is a poor metric of idle or average power draw, but it can be a useful approximation for max draw. (Of course, transient draw under turbo can very briefly exceed TDP limits.)
[I should qualify this by noting that both Intel and AMD have played shady games with TDP ratings in the past.]
I have experience building pc's yeah. Haven't really done a full server build until now.edited
2620v4 - you will be just fine splitting power from your existing 8pn cpu power *or* from the molex assuming you have a server grade psu in the 800w range *and* even if you load up your chassis with disks.
total load on your psu is gonna be the real test. all things being equal I *think* you will be fine but really shouldn't state that as a absolute since there are other variables to consider.
@Sean Ho is absolutely correct TDP is a poor metric for idle or average. note my comment said MAX and yeah turbo will briefly push past that.
absolute measurements of your specific configuration is the only way to know 100% for sure. If you are trulyi concerned. start with one cpu installed and one memory stick and NO add-in cards- which is a good idea anyway. make sure everything looks copacetic then add your other cpu , your additional power to the other cpu power socket and 1 memory stick for that cpu. Then add a card at a time. then add your memory to each cpu.
I'm sure you are experienced at building systems but I'll say this anyway (and no offense intended) double check your standoffs to make sure you don't have one in there that should not be there.
Perhaps a better way to say this is IMO/IME you aren't doing anything crazy or that hasn't been done before by someone else.
