Do extra PCIe lanes = better multitasking?

post #1 of 14
Thread Starter 
This is probably stupid but.. when I am downloading something from the internet to my eSata raid box, listening to something on iTunes, playing a game on my main screen and watching a sexy lady dance around in her underpants on my second screen at the same time my PC slows to a crawl. Same with transferring files between internal and external storage and any of those other tasks. The CPU/memory rarely is loaded more than 60 percent and I was wondering if there is a bottleneck from only having 20 PCIe lanes, and if I would benefit from added lanes on the LGA2011 boards.

If no, any help with the slow down/ too much stuff going on problem would be great. thumb.gif

PCIe lanes have NOTHING to do with what you have described. 40 PCIe lanes from LGA2011 is solely for GPUs (SLI and CF). Nothing else. Of course when playing a game and watching a movie will slow your computer down.

Hmm. I have no idea. I just want it to work. Any thoughts?

edit- I am assuming that the audio card and RAID card are each taking a PCIe lane and I thought that the SATA ports used some as well I have no idea.

Do you also fold while doing these other tasks?

From what you've described, they all involve the use of internal HDD and external HDD. Have you thought about defrag (yes it is possible to defrag RAID setup, and it helps)?

No folding during my Civ5/naked lady/accounting stuff sessions. I don't believe that disk fragmentation is a problem, but I would imagine that the hard drives could be the problem. Do you suppose a pair of m4's for the C drive and upgrading the raid drives to SATAIII would be helpful here?

edit- HDTune doesn't show any errors/problems and tons of speed, maybe I just need more speed?

Probably low memory (despite was Task Manager is showing). Or it could be that you need a faster disk drive, something like a SSD. wink.gif

How many HDD per RAID are we talking about? If it is just 2 HDD SATA III won't help. Your rear eSATA port is SATA II. You do have proper SATA driver installed right?

With M4 as boot drive, your Windows and whatever programs are on there loads faster, and does not depend on HDD.

External is 5 WD Black 2TB SATA2 in an eSata box RAID5 connected to a RocketRAID 622 in the Black PCIe slot in the bottom of the mobo at x1, and internally I have four SATAII WD Black 1TB mirrored and stripped on the mobo, and the boot. Too much going on?

Your external setup sounds like a bottleneck going around. My suggestion (if budget is not a concern) would be to upgrade your GPU into a single GPU solution, and buy a x4/x8 RAID card and install it on your second PCIe x16 slot (where your second GPU goes). That way it has x4/x8 lanes instead of x1 lanes.

I'm not familiar with RAID. Hopefully someone will chime in. RAID5 is slower because of parity check, if data redundancy is not a concern RAID0 is faster.

You do realize that Civ 5 gets pretty intensive in long matches right?
