New AHCI Driver Confusion!

[MongGrel]

Change it to AHCI and do a clean install?

Your posts are vacillating all over.

But have at it.

Some things you list are hardly new, but I digress.......

which is supposed to include the entire AHCI spec as a subset of its features.

U had me at "....the entire AHCI spec as a subset of its features.":wub:

I mean it: the jewelry, the fllowers, the compliments don cut it for me.....just give me THAT species of uncommon richness!

Now, as I recently shared, I am on RAID in the bios....and have come to feel what you share above is true. But now, I am not sure if, as was in yr case....I am missing something.

That was an obvious option from the get. It remains the one I am trying to avoid.

Nope. I am on a journey, and there are no straight lines in the natural world.....and life would not be as rich were the journey more linear.

Mongrel... this is neither a peeing contest nor the NBA playoffs. And, I, for one am free of any hobbling need to make anything into either.

this is all largely a non-issue. don't worry yourself over it. btw, trim IS supported on legacy IDE on Windows 7, so the presence of active trim commands does not mean that you are running ahci.

If you have BIOS set to ahci, and windows boots, then congrats, you are running ahci mode.

 

[tcsenter]

Yeah, he's a thick headed one. We gave him adequate instructions on what to do from the get-go but somehow he has decided not to follow any of them.

FYI Virgo is female.

I'm temped to take her off my ignore list just to see her reasons for not following instructions.

 

[G73S]

I won't bother giving her any advice anymore, all the long messages I posted saying that nothing would beat a clean install with the proper AHCI mode set in the BIOS from the beginning rather than doing some bogus reg tricks which may or may not work. but her thinking that having TRIM commands really means that she is in AHCI mode, I gave up, she simply won't listen.

by the time she had been in this thread reading and trying, she could've already finished her clean install and ensure she is using 100% of her SSD's performance.

I'll add her to my ignore list too.

Thanks for the suggestion Phynaz

Just stunning....any human can be so insecure as to believe any other human is on the planet to FOLLOW THEIR INSTRUCTIONS.

No such being would ever be admitted to any reputable, forget formidable academic community....nor would any survive there. Forget the inelegance of this phenomenon.

There is a history of forum veterans exploring and unraveling the facts about RAid-mode, AHCI-mode, SSD TRIM, IRST software and ISRT SSD-caching. The problem of converting from IDE/RAID/AHCI to either of the remaining modes so that Windows boots is integral to obtaining certain "feature requirements" like RAPID in Samsung Magician for Sammy SSDs.

RAID does include AHCI as a subset, but only in more recent BIOS versions and IRST versions does it hold TRIM promise for multi-drive RAID configurations. You DO get TRIM for single SSDs on a port with RAID-mode BIOS configuration, but you can't get RAPID in Magician unless the BIOS SATA configuration is AHCI.

Wow. One of many reasons I cherish this community, is, it's clearly populated by many (not all) brilliant, emotionally intact, elegant humans---MY kinda humans. I would say it's awesome, but I try not to use that word. What it is is precious and uncommon.

I also got early on in this thread, this arena is infinitely dense and nuanced....not linear.

RAID does include AHCI as a subset, but only in more recent BIOS versions and IRST versions does it hold TRIM promise for multi-drive RAID configurations.

Ahah! So good to know this esoteric fact! I believe my current bios qualifies.

You DO get TRIM for single SSDs on a port with RAID-mode BIOS configuration, but you can't get RAPID in Magician unless the BIOS SATA configuration is AHCI.

Yes, as I shared, first thing i did after installing the drive was to make sure my TRIM was doing its thing. And then, I found that amazing little DOS app written by that Russian guy, Valdimir.

I now almost regret not having chosen a Samsung....simply because of this Magician. Alas, Crucial drives have no such thing.

Can you please explain what "RAPID" is?

Wow. Even more now.....I kinda wish I had gotten a Samsung. Fascinating white paper!

 

[G73S]

but you can't get RAPID in Magician unless the BIOS SATA configuration is AHCI.

that it is certain.

at the end of the day, for optimal performance, one must have his BIOS in AHCI mode and doesn't need even the IRST driver if he/she does not have a RAID setup.

just my 2 cents

PS: Samsung SSDs seem to perform better in the AHCI driver than in the IASTOR IRST driver. just my observation

 

[sm625]

When I got my SSD I started off with a HDD clone that was actually in IDE mode. I then switched it to AHCI mode after several months. No noticable performance improvement. I then had to do a reinstall in which I started in AHCI right from the get go. Again, no noticable performance improvement. About a year later I upgraded my SSD to a larger, faster model and reinstalled windows. Again, no noticable performance improvement. My point is that simply having a SSD is what gives you the big boost in performance. After that, it doesnt really matter how it is set up.

 

[G73S]

Can you please explain what "RAPID" is?

http://techreport.com/review/25282/a-closer-look-at-rapid-dram-caching-on-the-samsung-840-evo-ssd

So with RAPID, you get similar speeds to having 2 drives in RAID mode but you are not actually in RAID mode. I love it, it uses 1 GB of your RAM which if you have 8GB+, you wouldn't care about as you want to use every bit of RAM you have to get max performance.

if you want something similar to RAPID but works on all SSDs,

try PrimoCache FTW:

http://www.romexsoftware.com/en-us/primo-cache/index.html

PrimoCache is actually better since it's not limited to only using 1 GB of your RAM when caching stuff but you can use as much as you want

A VERY IMPORTANT OFFERING! As we delve ongoing....and that takes courage, smarts and health.....we come to own more truths. Combo of cognitive ability and intuitive.

I knew going in as I had learned....the bigger the SSD, the faster. But 240GBs was more than plenty for my needs. Only reason I din get smaller was the speed issue.

Many thanks for this!!!!:thumbsup:

BS. You just like to hear yourself talk.

It just struck me to go check how Windows rates the function of this SDD......fascinating! And no need to write data to the drive.

Given I have 3GB connectivity with my SATA 2 controllers, not 6.....7.8 made me smile, and confirmed my subjective take: this puppy is functioning well.

even when I used to have one of the first gen SSDs, I got a 7.9 rating in WEI, that is not a benchmark you can count on by any means and is very inconsistent. Example, with my 24 GB RAM sometimes it give a 7.8 rating and sometimes a 7.9 rating, that is after a fresh reboot and waiting for a few mins till all services/programs are loaded. very buggy benchmark but it's nice to see nonetheless

Can you post results of Crystal Disk Mark or AS SSD Benchmark so we can tell you if it's running at the suggested speed that it should or not?

Is it still unclear that you (and your riddled by feelings of inadequacy, pitiable bully peeps in this thread) are persona non grata?

Pls move on and manifest your issues elsewhere.

It struck me that the advice G73S shared here was meant to be helpful. I would agree with that advice, and the general strategy of helping to figure out that everything is working well, exploring other tools to verify things, and providing warning that one single tool may be unreliable and give a false sense of security.

It is possible to turn away from other sources of knowledge when you get one good piece of evidence, but wisdom visits those who seek to discover all knowledge available.

I am struck differently. And I stand my my struck.:whiste:

You don't know me, and so, I forgive you for trying to tar me with a broad, sloppy brush belying my reality. To mix a metaphor, the shoe....don FIT.

As I have written about often: it's not where you go, it's where you are coming from which impacts what you bring. I get paid to be a keen judge of individuals and agendas.

I ran benchmarks and put ups screenies of benchmarks in this forum not long after I installed the drive.

The speeds are just fine, tho, naturally capped by my board's SATA 2 controllers and 3GB connectivity.

Having now learned what I did about running benchmarks on SSDs.....I have neither the need nor the intention of running more.

This bios issue is also, I have just learned (I am relentless re chasing truth)....is board specific, i.e., my board is intel.

You forgot to mention MB and which

controller​

​

it is on.
If AMD - ahci
If

Intel​

​

- ahci, sata, raid makes no difference as long as The SSD is NOT a member drive of a Raid0, or 1, configuration and you have loaded the latest intel RST driver (ver 10.6 or later). The driver iaSTor is better than msahci and will pass the Trim command.

And, I just came upon this re a guy with the identical Crucial, also with SATA 2 limitations, head's up: this is form the CRUCIAL FORUM....the horse's mouth as it were.

Another edit:

And, the guy in question with the identical drive & same SATA2/3GB limitations, has less good than mine benchmarks, in fact, HALF my score using the same app--- did a fresh install in W8. SOOOOO interesting. Someone commented in that thread....intel makes far superior SATA controllers than anyone else!

That alone might explain my benchmarks are better than his. And he was told by all who weighed in---all CRUCIAL PEOPLE----HIS speeds are fine.

So jus do the math.

Every second......more FASCINATING STUFF!:wub:

I am focused, delibrate/relentless in chasing data relentlessly. I now get absolutely....I am good to go. And, given the indigenous facts.....better than some! Finding that Crucial site and that thread with the hard data.....was hugely helpful and confirming of that.

I read through the earlier postings, but I was not able to see, what kind of computer did you use for installing the SSd?

Sorry, was on with a client.

Do U mean my specs? I will assume so.

This is an Optiplex 980MT (the biggest configuration, ATX) Desktop, Q57 chipset; LGA1156 socket; Lynnfield i7 870 2.93; 8GBs DDR3; ATI Radeon 4550....running W7-64-bit.

I am writing from the drive at this moment, of course; this is the drive I now almost always boot into....my WD Black is now used as my backup drive.
