PERC 5/i RAID Card: Tips and Benchmarks - Page 616

post #6151 of 7150
just a quick question.

my perc 5i is in a x16 slot running at x4, would it offer much of a speed increase swapping it into a x16 slot that runs at x16??

i have 6 2tb drives running in 2 raid 5 arrays with a global hot spare.

My only conclusion is that my battery at 800 mAh is not enough for a 512mb module. As this is my first (and only) perc 5 I've ever used personally (or had access to in a professional environment, companies I worked for mainly used HP Proliant servers) I am unsure if this is the correct conclusion. I will buy one later as it seems mine is below the rated maximum capacity it should be, and will need replacing at some point, anyway. Later when I do get said new battery I'll see if the 512mb works. But for now, since I can not use the BBU with my 512mb installed, I'm back to the 256mb for now, and the 512mb goes on the shelf in the closet for the future. At least it's cheap, and I have it here on hand for when I can use it later.
Also I wanted to thank you bobfig for showing me that Trip-Lite SATA cable a few pages back, I ended up buying one off ebay and I'm using it with my 4 SATA drives on my PERC5 for a while, working great! smile.gif

just want to say i got the stick of ram and put it in and got the battery not good enough also. so ima get a new battery.

lol, I got my 512MB stick and everything is perfect. My speeds seem better overall in use too. biggrin.gif

EDIT 3: Yay! Sleep works with the LSI drivers. Using my perc5 re-flashed LSI and using the dell drivers, my i7 never would respond when it came back from S3 sleep mode, but it does now with the LSI drivers.

Could you go more in-depth on how you edited the inf file to get the LSI driver to work? It would be amazing if I could put my system to sleep (although I could hibernate) for short periods of time.

Here: http://www.outfoxed.net/perc5i/Windows_7-64-bit.rar

Again, this is a slightly modified version of LSI's latest signed 64-bit driver, modified to include the PERC 5i after it's been re-flashed to LSI firmware. These are for windows 7 64-bit.

Standard disclaimer: Do not hold me responsible if these drivers destroy your machine, cause instability, bluescreens, loss of work due to crashes, cause your computer to catch fire, cause your perc 5 to catch fire, spawn satan in your bedroom, your computer manages to sacrafice a goat, or......... anything else. Use at your own risk.


However, I've been using these for about a week now and they work perfectly for me, and I've put my overclocked x58-based i7 to sleep and woken it up multiple times with these drivers. And I mean S3 deep sleep where everything is powered down. It does take about 30-60 seconds after resuming from sleep to return to "normal operation" though. So have to sit there and wait on it to come back to life.

Hmm I tried it, but it still says that the existing driver is up to date. I flashed my card to the latest LSI firmware in the first post. Oh well.

Yes.. if you want to use a different driver, sometimes you have to manually force windows to take it, most of the time the "automatically find a new driver" won't load the driver you want it to load just because it "isn't newer than the one you already have". In the driver update dialog window: Browse my computer for software -> Let me pick from a list of device drivers on my computer -> Have disk button -> Browse button, browse to where ever you saved it, leave "show compatible hardware" selected, select what shows up (should be "LSI Logic MegaRaid SAS 8480E RAID Controller") and proceed.

Windows automatic driver loading is stupid.

No it wouldn't help you. PCIe 1.0 x4 provides you with 533MB/s of bandwidth, and I kinda doubt you're using that much in either of those raids. Even if you would go to x8 slot, the PERC 5/i maxes out at 800MB/s, so I've heard.

Tried that already, caused my raid card to not be recognized and had to restart then re-install default dell drivers. I tried to browse the folder to the one that you provided after unziping it, and it still wouldn't take it.
