Force trim tool for 840 pro?

[Psyside]

Is there any available? thanks.

If I'm not mistaken, you can use Samsung Magician software to force a TRIM (in any OS - Vista, XP, etc) on the 840 Pro. You cannot do this in RAID though (at least that I know of).

I don't see the option in the magician software?

But what i saw, is like 120Mb/s less sequntial read and like 60mb/s seq write in AS-SSD benchmark..this is with fresh system (2 days) 25% OP, and all power savings turned off (static cpu clock of 4.7GHZ 2500K)

I really have no idea, what can cause such large drop in just 2 days, especially with like 50GB left for over-provisioning.

In Magician look for the feature called "Performance Optimization".

Install the latest intel RST drivers.

Try SSD Tool to manually trim.

Did it help your transfer rates?

It did, but my read scores are low again, i dont know what is going on

Performance is like 130mb/s less regarding seq reads...

Can anyone tell me if this are good RST drivers, maybe they are the problem?

12.8.0.1016, and please post link for a bit older but more stable once? thanks.

I rebooted, and performance are back to normal, but this is the second time i see quite a bit lower performance.

What could be the cause?

Use ATTO. That is what most manufacturers use for benchmarks, from what I have read.

if your cpu is downclocking to x16 [intel] run something in the background to kick it up.
-I keep my 3770k idling at 3.5 ,then to 4.6 oc by turning up all the power options.

I got fixed cpu clock, never goes under 4.7, everything is MAXED out, c states have no effect if your cpu is having fixed clock, i know this and have tested it, so i guess some process/application is the cause

What could be the cause?

Excessive benchmarking?

 

[Psyside]

Nah, i done like 1 hour all in all in like 3 days....with forced trim, and idle log off (force GC) for like few hours 2 days in a row......really haven o diea what can hold back read performance? i know writes, but reads? really strange... thanks for the answers btw.

Also i got every single tweak on, fixed cpu clock, write cache buffer flushing - off, latest RST with power savings turned off, latest chipset, latest UEFI, 25% OP and so on...

I'd move the drive to another port and see if anything changes.
