Thanks for sharing!   You could have just uploaded it to a file host instead

I know how to deal with it though, thanks again for sharing!

Also, no worried about this being a beta BIOS, we host and use beta BIOSes all the time, see here

Yes, I knew this could be done simpler...  
But I'm afraid I don't have any experience with file hosting.

I saw you already uploaded F9A at TweakTown Forums.
Thanks, this makes it easier for people to download.

Ahh no worries, but in case you want to know for future use you can google free file host and pick one.   Some let you upload without an account, others you have to have an account, and some of the free ones you can make an account on anyway that way you can keep track of your files and links.

Yes I posted as soon as you shared the file, thanks for sharing!   We try to help all Gigabyte users, so having random beta's like that are nice to get, because we'd get it eventually, but since you posted it's now sooner rather than later

Man, I had to look at your thread didn't I?

I had to test, otherwise it would have bothered me in the back of my mind until I did!



C3/C6 setting has no effect!   I have not tested EIST and C1E, but I'm sure after the fiasco here they know what to look for and fix.

So, needless to say X79 is also affected by this, report going in now!!

[GTZaskarLE]

Yes.
No complains to you, but if you as 'hero member' had looked earlier into this you could also have pushed Gigabyte harder, together with Bernice (from Gigabyte NL) and me, and then this issue maybe got solved earlier.

It took almost for ever, but they did it.
In mean time DM was temporarely lost 'deep underground in his EMP nuclear proof bunker'.
(just joking DM )

And if I understand you correctly;
Yes, the C3/C6 state setting does not matter anymore for SSD performance.

My main issue was that all processor energy saving features like C1,C3,C6 states and EIST should not have impact at SSD performance.
I saw bios version F5 working correctly, but all versions after that gave severe write performance hits.

Until now.

And yes, this is probably something to focus on too for other chipsets.

[Lsdmeasap]

What do you mean "Hero Member"?

But yes, I'm sorry I never saw this thread earlier, I'm not always here as much as I would like, so there is times I may miss many threads I would have been able to help with!

I tested C3/C6 because I thought that was the main setting that initially allowed you to have or not have the bottleneck.   Should I also test C1E and EIST and see if those enabled or disabled remove the bottleneck?   I guess it really doesn't matter, as I'm sure they know the exact cause and which settings can effect it anyway, so I'm sure they'll fix it up soon since they just recently found this fix for you. 

I see P67 and Z68 affected now too, so it must have been some recent BIOS change or addition that created this, because when I reviewed P67 UD4 and UD7 (B2) this was not an issue at all, probably just like you mentioned with the older BIOSes not having it

You are right though, none of these should have ANY effect on the SSD speeds, but I do often see speedstep having a little effect on speeds (Same as using a balanced of power save plan in windows), but nothing like this write bottleneck.

Again, I'm sorry for these hassles you had to go through, and the long amount of time you had to wait for a fix!!

[GTZaskarLE]

Well, I saw in your profile: position 'Hero Member' and you are very active here and at TweakTown.
So I probably was wrong about your involvement at this website.
I thought you are some sort of administrator here, connected with Gigabyte.

But no worries, I know you follow lots of threads, are only one person and cannot be everywhere.
I didn't want to make you feel responsible. In addition, internet makes conversations always different from when you speak in person with somebody about something (and in your own language). Things can easily get out of proportions and that wasn't my intention. I only was a little annoyed about GGTS in general, but not anymore.

Concerning testing C1E and EIST: I already saw it has no impact anymore with F9A.
If you want to verify, please feel free to do so, it is always nice to see something verified/confirmed.

If this is really something recent?

All I know is that is affected my Z68 board for more than half a year, let's say after F5.
It probably affects also P67, but I cannot be sure.

On the internet I found not much about this, other than disabling C3/C6 states which was not the solution for me.
Let's hope Gigabyte fixes this for the whole range of existing P67 and Z68 chipsets.
And pay attention for next generation chipsets too.

Ahh, sorry, I didn't even notice that was my user group until you mentioned it!   I think that may be based on my post count, or some mod or admin may have set it like that, not sure?

Yes, I am very active for Gigabyte at many places, and I try my best to make my rounds to many forums, this one included!   I am just a normal user here, but Admin at Tweaktown.   I don't work for Gigabyte though, but I am directly in contact with them, so I guess you could say I am connected with them in that aspect, but in the end I'm just a normal end user like most everyone here.

No worries, I wasn't offended by what you said, just a little confused as I wasn't sure what you meant by Hero until now

I'll try to test with C1E and EIST later tonight if I get time, but as you know I've already sent in a report on this issue for X79 and they are working on it already.   And I know they are also working on other boards BIOSes for this issue as well, so hopefully they'll have it sorted out for all models very soon.   It's odd how it affects ATTO only, but not AS SSD or CDM!?

Ya, I'm not sure when it started, but I know it wasn't always like that as you mentioned, because I did reviews on P67-UD4 and UD7 a while back and they were not affected then, but may be now (haven't checked yet, but will)

I'll keep you posted once I hear back on a fix for X79 in case you know other affected.   You can also keep an eye out here for new BIOS releases, as the may be released with fixes mentioned in the change notes, in case you or anyone else reading wants to keep an eye on other boards that may also need corrected

UPDATE
In mean time OCZ has released new firmware for the Vertex 3 maxiops: v2.22

The test results are good, see attachment.

I wonder when Gigabyte releases F9 for the GA-Z68X-UD3P-B3 motherboard.
As soon as they do I'll test if the F9A improvements are copied into it.
That's the 'SSD write speed in combination with C1E, C3/C6 State Support and CPU EIST Function enabled' fix.

[Dark Mantis]

That is looking much better now. Those are some good figures.

[BIGguiX]

hello everyone.

i resurected this old thread today

Slow SSD Write Speeds? Try This

then i found this one.  Its not the same motherboard i have, i have the z68x-ud3h b3 rev 1.3 F12 but i still seem to be locked in write speed even with c3/c6 disabled.

anyone found a workaround for my board especially ?

you guys seem very helpful i tough i'D give it a try



MERCIIIII


*******  EDIT FIXED **********

i had to set c3/c6 to disabled AND cpu halt state to disabled for it to fix my problem !

[GTZaskarLE]

Hi BIGguiX,

As far as I know there is (still) no Bios version (yet) for GA-Z68X-UD3H-B3 which fully fixes this problem.

The main goal within this thread was to get full write speed for the SSD with all CPU energy saving functions enabled.
So setting c3/c6 to disabled AND cpu halt state to disabled will give you maximum write speed but without CPU energy saving functionality.

If this is enough for you than you could decide to accept it.
If not, then you could ask GGTS for a solution.
Use F9A for GA-Z68X-UD3P-B3 as reference.

Good luck!
