Intel 750 ssd on Evga X79 Dark mobo with 3930k

firen — Wed, 02 Dec 2015 10:43:44 GMT

Hello Guys

i am deciding to buy the intel 750 pcie ssd and i was wondering if i can get the full speeds of the ssd or not.you can find my pc specs below;

CPU : intel 3930k 40 Pci Lanes

mobo : Evga X79 Dark

as you know 3930k is not officially support the gen 3.0 but my mobo Evga X79 Dark has Pcie gen 3.0 slots .So what will happen if i place my intel 750 ssd into one of the pcie gen 3.0 slots?is it going to run in gen 3.0 standarts or gen 2.0 standarts?

i am a little bit confused about that.I mean , is the ssd going to work as gen 3.0 even if the cpu officialy doesnt support pcie 3.0 ? or is it just going to need x4 available pci lanes in CPU?

or is it just going to take attention the slot that it has been running in?

Kind Regards

Some motherboards vendors have an option in BIOS to force gen 3.0 mode even on officially unsupported Intel CPUs, check MB manual and/or ask EVGA support about it.

yes the motherboard has pcie gen 3.0 slots and i can set them up in which mode (gen 2.0 or gen 3.0) they will run at.But as you know the intel 750 400gb is a little bit pricey so i just need to be sure that the intel 750 is going to work at its full speeds

Unfortunately, i`m personally seen no success reports with your exact MB model, but some X79-based MBs was able to run 750 at PCIE 3.0 level.

On 2.0 likely only linear read performance will be visible hurt.

Spirit,

You did not mention if you needed boot support. The drive should work as a data drive.

As PCIe 3.0 ? there is a good possibility but I have no experience with the EVGA x79.

However the Intel X79 chipset based boards don't have full NVMe boot support in BIOS. That was implemented and validated with X99, Z97 and now Z170 chipsets.

what if had 4930k instead of 3930k ? as you know 4930k supports gen 3.0 officially.my concern is here 3930k doesnt support gen 3.0 officially but it is capable of supporting gen 3.0

I read through that link. It looks like in Post 21 he is using an Intel Core i7-4960 processor.

Officially that is the reply. "Support" is with validated hardware and that hardware is the i7-4960 and similar processors.

I have seen and used the SSD as a data drive on a DX79SI (Core i7-3960 processor) but that is not validation, just install. You would need to be prepared to go to a validated configuration if the performance doesn't meet your expectation.

Looks like 750 (or Intel NVMe driver) just nevermind about host capabilities and always throw PCIE Gen3 mode . No boot, of course.

thank you so mich for the information so it looks like it will run at full speeds.is it possible to do as ssd or crystal disk benchmark tests for reading and writing speeds?

and why did you say no boot option ? is it because of the motherboard ?

Re: Intel 750 ssd on Evga X79 Dark mobo with 3930k

AP16 — Thu, 03 Dec 2015 23:12:37 GMT

I can, but this have no sense, cause:

2. This exact SSD is already tuned to databases performance (non-default sector size) and should not be used as reference from any point.

Yes, it cannot be used as boot drive, Intel X79 MBs was not conform with UEFI v. 2.3.1 spec (and probably lacks NVMe EFI driver in BIOS).

is this the test you have personally done?

thanks again

Yes, it`s mine. Please don`t loose a note2: this SSD configuration is changed from default.

firen — Sun, 06 Dec 2015 14:33:09 GMT

what do you mean by the ssd configuration is changed from default?

and for the boot device isnt it up to the motherboard? so the guy in evga's forum mentioned that he can boot from intel 750 so it seems the boot process nvme up to motherboard?

Intel board do not support boot from 750 (old UEFI and so on). EVGA may be (if someone in EVGA make BIOS changes needed).

ssd configuration is changed from default

750 have a bunch of parameters, configurable via isdct.exe, some was changed from default values for databases tasks purpose. Nothing you need at home though.
