Windows 7 - Show us your SSD performance

Would have to look a the code to get really specific but I was assuming that that means that there were 64 threads launched all reading 4k blocks at the same time and the total throughput of all threads combined.

At any time your Windows and programs can be running 100, 200 300 or more threads at once with quite a few of them doing File IO.

It appears that the standard IDE drivers only allow a single thread to access to the drive at a time whereas you can get several more threads asking for data at the same time in AHCI mode which probably handles Windows overlapping IO modes MUCH better.

This probably helps with program launches, boot time and single specialized prgrams that use multithreading properly and do heavy disk IO.

In the 4K test, the speed of random read/writes is measured. The 4-64K test is similar but read/writes are distributed over 64 threads. It is designed to show the difference between IDE and AHCI modes.

Edit: fseal was faster - lol

Looks much better.

What is the new motherboard?
Is it in your system specs or is that the old one?

Sorry Dave , I forgot to update my system spec last night.

Done now.

Its an Asus P5QD Turbo btw.

What are the temps?

Did you run Prime95 or equivalent stability test?

Different motherboards will sometimes not overclock the same.

Could be due to the P45 / ICH10R chipset or other settings in the new BIOS.

Whats the VCore running at?

Hi Dave ,

The temps look just like before , I always keep an eye on my temps no matter what just of of interest more than anything. Didn't go above 50 on any core.

Didn't really see the point in running prime95 when I know its not stable for more than a few mins anyway lol.

It appears that I cannot seem to overclock at all now , as the system had starting rebooting for no reason just with a 100mhz overclock.

I never touched the Vcore on the old board and had 3.1ghz just fine , I tried upping it to 1.3 with a mild overclock on the new board but it makes no difference.

Current Vcore is 1.264 back with standard settings on everything.

Tried the memory at all sorts of speeds but that makes no difference.

Tried disabling usb things and all power saving things in the bios , no change.

There doesn't seem to be many people on the net with this motherboard and I am struggling when searching for info on it.

I am a little puzzled.

This is very off topic for this thread so perhaps a mod could split it off to the overclocking forum or I may start a new thread later.

Cheers

My OCZ Vertex 2 SSD

Got to be a setting holding this back.

Did you update drivers and BIOS?

Your right not much info from searching.

Call Asus, see if they have anything about this issue.

Best to start a new thread in the overclocking forum.

OCZ-Vertex2

I had Windows 7 installed on a Velociraptor drive with ACHI.
I simply backed it up with the Windows 7 backup, replaced the Velociraptor with the OCZ Vertex2 straight from the box, then booted to the Microsoft "System Repair" disk I had made in the backup. I just told it to restore everything from the Velociraptor drive to the OCZ drive, and it worked fine. When the system came up it recognized the OCZ drive as an SSD. I just forced the swap area to be on the D drive, and everything seems fine.

I'm a little worried about the SMART "Reallocated Sector Count", but the numbers haven't changed since I installed so I suspect it's OK.

I tried turning off "disk caching". This made the system slow and weird, so I turned it back on. Supposedly this SSD has no internal cache.

Would you mind let me know what condition the PC shows is good? Thank you very much.
