Question 1

I saw different memory supports for different CPU on MSI motherboard. So, 7900x is a 16-Lane CPU or it is a 44-Lane CPU?

Accepted Answer

The 7900X is a 44-lane CPU.  However, this is 44 lanes of PCIe, which is used for video cards, SATA drives, M.2 drives and USB, not memory.  Intel states that the 7900X supports 4 memory channels for DDR4-2666 memory, with a maximum of 128GB.  HTH

Question 2

can I use ddr4 2400 ram for this?

Accepted Answer

yes, but it is below what the system can do.. which is almost 2x that speed

Question 3

Why would I buy this over the 1920X or 1950X?

Accepted Answer

AMD has designed their cores to take 2 cycles to process AVX instructions; Intel processes them in 1.  So if you're running code that takes advantage of these instructions, it will run significantly faster on the Intel chip.  Other than that, the AMD chips are a much better deal.

Question 4

The truth?  Will not one of you paid shills tell the truth about how shoddy the X299 boards perform? About how the whole i9 series overheats, even with liquid cooling at stock clocks? Or how the reduction in L3 cache has hurt gaming performance? The 100ns latency between every core? Are you all seriously going to lie, mislead and misrepresent a failed product? Be series. Everyone considering purchasing this, read actual reviews first from reputable sites and ignore this paid shills in the Q&A section here.

Accepted Answer

I wish I was a paid shill.  Could use the money.  :)  I find it funny that you call people saying they like this processor paid shills.  Your answer seems to reflect that as well but in the opposite camp.  That being said, what is your experience with the processor?  What have you tried? I am not saying this processor is perfect but it is currently the best out there.  Heat issues for the average user will not be problematic.  Motherboard manufacturers are already adjusting bios and in the higher tier boards coming out making sure the VRM issue for Prime overclockers is fixed. I am not going to argue that AMD has some attractive options out there but this processor does not deserve the hate that it as received in my opinion.  Expensive, yes (cheaper than prior generation), running hotter, yes (but not unmanagable), is it fast, yes (depends on the use).  I wanted a good overall processor that could handle everything I threw at it and this did the trick.

Question 5

New rig with i9-7900X, ASRock X266 Taichi, 4 120MM and 2 140MM fans. No OC on this rig, just stock setup for photo editing. Should I add CPU cooler?  If so, water cooler or fan cooled?

Accepted Answer

I think you definitely get a cooler. I9 does run a little bit hot. Especially you are doing cpu intensive work. And to answer your 2nd question, both coolers will work just fine if you dont OC. The advantages of water cooler is your pc will run quieter, and it is easier to work with(air cooler sometimes are very big and bulky, and you might run into compatibility problem), and water cooler just looks alittle bit better in my taste. The advantages of air cooler is the price. In summary, with either cooler you should be fine, but definitely get a cooler. Hope this can help!

Question 6

Is there an intended use/purpose for which this processor is tailored to? For instance, is it aimed towards intense graphics editing or for gaming?

Accepted Answer

A: "aimed towards" is of course a marketing question - that's my Business degree talking. Yes, the i9 is a multi-faceted processor. I have enjoyed extraordinary improvements in single-core & multi-core programs. The processor is able to shift internally & quickly between the two options - which, is a boost in efficiency for all task. Once the rest of the world (Vendors / Developers) catches up to the i9-7900x, it will be extremely difficult to match its performance in mainstream / real-world number-crunching.

Question 7

Why would anyone buy this over the R7 1800x? Twice the price for two more (weaker) cores, on a miserable  chip set. And it over heats.

Accepted Answer

lol The Overheating this is not true, Im running mine at 4.5GHz overclocked with a custom built liquid cooling loop and the max temp i ever reached while stress testing was around 70C. i do have a pretty good cooling loop and have spent alot on it so that does help. it does overheat if using air cooling or a h115i. you need a custom loop to cool good. i stand at about 30-35c while under normal load and have not had any problems. i have always found amd chips to be cheaply made and poor quality. Stats show that this cpu hands down smashes the R7 1800x.

Question 8

Which cooler should go with this processor?

Accepted Answer

EK Supremacy EVO

Question 9

Intel is going backwards, not forward.  You have to buy the Extreme to get 4 more PCIE lanes than current 6xxx series and with half the L3?This is not impressive at all.  I have a feeling my next upgrade will be AMD.

Accepted Answer

Half the L3 cache but they quadrupled each core's L2 cache from 256KB to 1MB.  That is impressive.

Question 10

Will you ever have any in stock to purchase?

Accepted Answer

newegg needs to get rid of the 3rd party sellers who charge almost double the price do not pay more then $939.00 for it
