I have been a lurker for a while (particularly when I built my computer earlier this year), but now I'm in need of some advice. I do a lot of AutoCAD work and have recently come into an issue. In trying to follow the forum rules, see below:

Approximate Purchase Date: e.g.: ASAP

Budget Range: Depends, I suppose, on what may be my bottleneck.

System Usage from Most to Least Important: AutoCAD, Revit, Adobe Suite, Sketch Up, Quick Books, Browsing Internet, and way down the list - gaming.

Are you buying a monitor: Not in the next 6 months.

Parts to Upgrade: RAM, perhaps?

Do you need to buy OS: No, I currently use Windows 7 Home Professional (I own the copy, I bought it earlier this year when I built the computer).

Preferred Website(s) for Parts: Flexible, possibly newegg or amazon.

Location: Atlanta, Ga

Parts Preferences: No Preference

Overclocking: No

SLI or Crossfire: Not Sure (probably neither?)

Your Monitor Resolution: (2) x 20" 1600 X 900, (1) x 23" 1920 X 1080

Additional Comments: none

Existing Components:
Processor: Intel Xeon E3-1220V3 3.1 GHz
http://www.newegg.com/Product/Product.aspx?Item=N82E16819116907
Mobo: ASRock Fatal1ty Z87 Killer
http://www.newegg.com/Product/Product.aspx?Item=N82E16813157460
RAM: HyperX Black 8GM (2 X 4GB)
http://www.newegg.com/Product/Product.aspx?Item=N82E16820104360
OS and Apps SSD: Samsung 840 240GB SSD
I only keep windows and programs on this drive.
Active file SSD: Kingston V300 SSD
this is where I keep all of the files I'm currently working on (active projects).
Storage Drives: Hybrid for Archive files, HDD for backup
Probably not an ideal configuration, at some point in the future I'll construct (or purchase) a proper backup system, but for now, this works for me (these are old drives I had).
Graphic Card: NVIDIA Quadro K600
This card is used for 1 20" and the 23" monitor for running AutoCAD, Revit, Adobe, etc (sometimes as dual instances).
Graphic Card: NVIDIA GeFore 210
This card runs one 20" monitor that is dedicated solely to email and web surfing (and the occasional PDF).

And Most Importantly, Why Are You Upgrading: I do a lot of AutoCAD drawings. Initially, I only worked on drawings under about 5mb in size and even as a dual instance, it didn't really bog my computer down (only occasionally, if I was zooming in on a "busy" portion of the drawing). Recently, I have been working on larger projects, and drawing sizes have ballooned to 14-20MB. AutoCAD has noticeably slowed down, taking a minute or more to open a drawing and running slow on all action (If I need to open, edit, and plot 10 drawings a day, I'm losing an hour or more just in waiting on CAD to catch up to me, so I'm spending hundreds of dollars a week waiting on my computer). I haven't really worked on any large Revit drawings, but Revit is generally more system intensive than AutoCAD, so I can only suspect it will also be slow.

When I watch the windows performance monitor when doing these larger drawings, I notice my CPU rarely goes above about about 70% of usage and usually stays in the 10-30% range even under heavy work, whereas the RAM will hold steady at about 80% capacity with a single instance open on a larger drawing. So, I think this is my bottleneck - but I wanted to run my full scenario by the community, in the even it's another issue.

Anyway, if RAM is my issue, The HyperX black I have doesn't seem to be available anymore (amazon has it, but the price has gone up to $110+). I'd hate to waste the $80 I spent less than a year ago, and would like a compatible ram (as 16GB or 8GB) to use in conjunction with the ram I have. I contacted Kingston and they said their new Fury line is compatible as long as I don't overclock (which I don't), but I was wondering if there is a better option out there, as the Black Fury ram has different CAS latency and voltage. I haven't had any luck finding ram that matches the specs of the ram I have.

Thank you for taking a look, and I appreciate any help you may have to offer! Please let me know if you need anymore information and I will do what I can to answer.

what is your main gpu usage?

have you tried updating the drivers on that, thats most likely not the issue but it may help.

I wonder if its more of an issue with your ssd. i looked into this issue and have seen some issues with this drive. there are two variants the older fast drive or the newer much slower drive.

i would test your ssd speeds with a benchmark tool and see what you are getting as well as testing your drive to see if it may be defective.

also see if there is a firmware update as well.

one way to test is move the files you want to open in autocad to you OS ssd and see if it opens quicker

Thank you. Sorry for the length of my initial post. The link you provided seems to confirm that possibly my RAM needs upgrading. Do you have any suggestions for:

"...The HyperX black I have doesn't seem to be available anymore (amazon has it, but the price has gone up to $110+).

Thank you.

Corsair Vengeance was the closest I could find to your original specs: http://www.newegg.com/Product/Product.aspx?Item=N82E16820233144

According to this post, it should default to the latency of your original RAM speeds (since Vengeance should be faster...?): http://www.tomshardware.com/answers/id-1797487/latencies-ram.html

You'll need to undervolt the original RAM sticks to 1.5v: http://www.tomshardware.com/answers/id-1702500/mixing-ram-voltage-problem.html

But if Kingston says the Furys should be compatible, I'd just try those.

Ideally he'd be able to get the exact same RAM sticks >_> have you tried searching with those specs he provided?

Kohwali and 06yfz450ridr,

Thank you for your help so far. I updated drivers and firmware. It's improved a little, but not really anything substantial.

I may just be better off buying 16 gb of ram (2 x 8) that is faster, but perhaps has specs that are a little more common so when and if I ever need 32 GB, I can (hopefully) easily find a match.

At least if I went that route, I could try my existing 8 gb with it to get 24 gb, and if it doesn't work, I will at least still have 16 gb moving forward and I could possibly sell the 8 gb I currently have and recoup some of the money.

Make sure to get some mainstream RAM so they're in stock longer! I know Corsair Dominators have fast speeds but people always complain about them being overpriced. You could probably find some fast RAM for cheaper or overclock RAM (is that a thing? I'm not sure).

Anyways, good luck!
 
whats weird is i see the hyper x black on newegg 2x4gb for 82 which is about right price wise. they are indeed 1.5v sticks as well they have the hyper x reds for 79 as well on newegg

also have you made sure your corse arent parking?

run the tool here not the beta one its horrible

unpark them if they are, helps especially with laptops
