P750DM final checklist

Hey all,

So, I'm moving into this decade and saying goodbye to my old beast. But there's a few things I wanted to check before pulling the trigger on the P750DM:

- LCD screen: I would love to get a 3K screen but as is I can't seem to find one suitable.
- RAM: http://www.newegg.com/Product/Product.aspx?Item=N82E16820233889 vs http://www.amazon.com/Corsair-Venge...ords=Corsair+Vengeance+16GB+(2x8GB)+DDR3+2133
Am I missing something, or is it really just the timings that are different at 11-11-11-31 vs 11-11-11-27. Am I really just paying $84 more for something I'll be changing when I OC it anyway?
- M2: Worth it or not given I've already got an SSD?

Cheers,

Jahar

 

Well if you're buying RAM, neither of those will work. The 750DM uses DDR4 RAM, 260-pin.

Currently there's very slim pickings in terms of laptop DDR4 RAM.

This is what you want

Please don't buy a 3K/4K screen on a laptop! Please! It's just ugly! super tiny icons! But if you insist, then make sure you buy a good magnifier to go along with it. The G-SYNC Displays also have a 75hz refresh rate by default and are super smooth

as for the m.2 SSD, there is no comparison. SSDs are limited to SATA III speed and have reached the limit. an m.2 SSD which is connected to the NVME controller will give you RAID 0 like speeds without the hassle/risks of RAID.


here are my benchmarks from my Samsusng 950 PRO 512GB m.2 SSD





and here is the Valley Demo on my G-Sync display:

 

I bought that hyper x ram as well, in preparation of receiving my P750DM. Still waiting on getting the computer but the price was right and it seemed well regarded.

Just use your existing 2.5" SSD if you're happy with it and save some money ☺

Gotta be careful, it's not the M.2 connector that's giving you those speeds, it's that you're using a NVMe PCIe drive.

Those folks using a M.2 SATAIII drive won't see those speeds.

 

ohhh thanks for the correction. Rep added to j00

 

I assume you don't mean in windows right? Like I know third party programs can suck, but windows 10 itself has much better display scaling compared to previous versions.

 

@Matrix Leader coming through with the benchmarks! Glad to see that beast in action!!!

For 4k, windows should scale it much better now so you don't have the tiny icon issue anymore. While you can still choose to un-scale it and you may need a magnifying glass to find your way back.

For ram, you could also go with the higher 2400MHz http://www.newegg.com/Product/Product.aspx?Item=N82E16820104589

m.2 vs SATA III pretty close together really as far as speeds. The reason m.2's are so popular is you can still get the 2.5" HDD in there that allows for more storage space on the laptop, if you replace that with the SSD you would have to go external or ODD bay. While that may be an option, i think the best is just m.2 with the HDD. realistically, m.2's aren't much more than 2.5" so i just think overall best way to go for the best end experience.

 

I thought that the 3K one's didn't have the same issues as the 4K, but regardless it doesn't seem like I can actually find one.

So, the price for the NVMe PCIe's looks pretty absurd right now so I'll just wait.

I'm trying to work out why the Corsair with worse timing and lower MHz is the most expensive? On paper it looks like the Kingston is the winner but has anyone tried them out in the wild to see how these compare?

 

Anything above an FHD screen on a laptop is a joke IMHO

Price has nothing to do with quality, so don't base your decisions on that alone.

The difference between any of those sticks of RAM, in practice, is non-existent. Pick the one that's cheapest, which, in this case, happens to be the "best" one, the Kingston HyperX. Fastest speed/lowest latency.

 

All three are good brands. I'd agree that the Kingston is going to be the better performance, especially for the price compared to the others. The one thing I will say about the Corsair, and being higher price, is I have very rarely seen their ram fail (either in production or after it has shipped). Ram failure is pretty low anyways among those three from what I've seen, but at least that might be the one reason to consider it, in my opinion.

 

For now I would avoid m.2 pcie (nvme or ahci) drives. Unless you need to transfer large files between two of those drives on a regular basis, you won't see much benefit from them. Besides, on those scenarios they tend to thermal throttle. What makes a real difference on a daily usage is the small files read/write speeds (which the NVME protocol should improve) but on that regard the new 950 Pro's haven't improved much. Wait for more nvme drives to launch, and buy those which bring a substantial improvement in small files read/write speeds, then you'll notice an increased responsiveness on your OS/programs.

Remember, those advertised super high sequential speeds won't matter much for most of us, it's more of a marketing gimmick - "ohhh, those are super fast , my system is gonna fly!!" - not true.

You got that right. Different strokes for different folks.

My productivity would be hampered with a Fhd panel. Some programs I use have a really cramped UI with that resolution. With a 4k at 150% scaling i'm perfectly fine and have room to work fast. Besides, I need good color and gradient reproduction, none of which you can find nowadays on a fhd panel.

 

Ya NVMe is pricey right now (new tech), but as you see about 4 times the read speed and 3 times the write speed (or so). overall for price to performance i'd just go with a standard m.2 right now, unless you need the faster read/write speeds for a function that saves you money (or makes you money). You could get 1TB of M.2's for about the same price as 500GB of NVMe, put the M.2's in RAID 0 and you've cut the difference while having more space for the same money.

 

Well that depends on your definition of good. The LG FHD panel in use is 72% NTSC, 95% sRGB, which is really good for anybody that isn't in video/photo work.

 

Yep, that depends. For me my Sharp panel is just good enough, although for now it's the best panel available regarding color reproduction. That will change very soon. I just wish that the upcoming 15"/17" 4k 8bit ~100%AdobeRGB panels would be compatible with the P7xxXM chassis but unfortunately it seems to not be the case..

That Lg is a 6bit panel, as all other current fhd panels. Not a big deal for any non image related work. And let's not forget that the advertised color space coverage is rarely achieved, even after calibration.

 

Those numbers I posted are what my Spyder4 returned after calibration, so I can't really complain about false advertising.

 

Nice. As i said, after calibration you can get really close to 100% srgb. I'm just nitpicky, if i see 100% on the specsheet i expect - i demand! - real 100%.

On a side note: next time you buy a colorimeter, get an X-Rite i1 Display Pro. They're about the same price as the Spider, and more precise/reliable. I wander a lot around colourists forums and there's a consensus on this from the really knowledgeable guys (lots of charts, lots of tests, all certified by tens of thousand euros probes and top software as Callman and Lightspace ). For a small budget they're the best.

 

Thanks for all the feedback guys! I might hold off on the RAM till Black Friday to see if any of the DDR4 goes on sale but the rest looks good.
