AMD 1090T Black edition + Asus Sabertooth 990fx tuf edition 4.0ghz help? - Page 3

Nope, manually set the timings in your bios to the values shown in CPU-Z, under the SPD tab for 1333 (this will be shown as 666 Mhz due to double data rate : DDR)

Did you manage to find the timings in CPU-Z?

]So these are the timings that appeared when the ram was set to either 1333mhz or 1600mhz.



So, with that said, I will set these settings to my ram at speeds of 1600mhz followed by 1333mhz if stability issues occur. I will report back with the results. Wish me luck!!

After following your instructions, looks like pc is running fine. Temps on the cpu seem to sit around 46c-47c with the voltage at 1.4 at 3.8ghz. Going to push her up to 3.9 in another 5 minutes to be on the safe side.

Asus has some bizarre settings for LLC. It was originally set to auto, but the options were medium, high, extreme, etc. (0%, 25%, 50% 100%) I set these to medium. Should I raise this up if I see any instability?

**Update**
I hit a brick wall. I can't get her stable at 4.0ghz. Keeps blue screening during a prime95 test.

You're very welcome! I spent a whole lot of time with my 1090T, so believe me, I've been there!

Going back to your current status though, I would steer clear of messing around with your NB and Ram for the time being. First, what is V-Core Jumping up to once under Prime95 Load? This is very critical because you need to find an LLC setting that will, at the very least, keep the voltage constant when under load.

For example, on my UD5, I found that the best setting was the second highest in the LLC menu (Very High). I dont know why, but the extreme setting was worse. Under this LLC setting, this is what I managed with my own 1090T...

3.8 Ghz

Set in Bios: 1.425V
Idle: 1.44V
Load: 1.47V

3.9 Ghz

Set in Bios: 1.45V
Idle: 1.465V
Load: 1.5V

4.0 Ghz

Set in Bios: 1.475V
Idle: 1.5V
Load: 1.525V

However, although I could run 4.0Ghz and be Prime95 stable, I'd be lucky if I could stay in for 5 minutes on BF3 before it'd crash. So like someone mentioned earlier, 4.0 Ghz is on the further end of the spectrum, one that is more likely reserved for those rare golden chips. I kept mine at 3.8Ghz up until the day I sold it.

Once you've got this figured out, you can move on to CPU-NB overclocking, which will also be very beneficial to you. The goal is 2600-3000Mhz. I settled on 2800Mhz @ 1.225V.

You guys mention raising the voltage when I raise the NB up. Do you mean the CPU/NB voltage or just the NB voltage? or both?

I did a little bit of messing around with the FSB last night as well as NB and the pc did not like it at all frown.gif

CPU/NB voltage is what you have to raise. Keep NB voltage @ AUTO

Currently, my PC seems to do the best at 3.8ghz. As of know, rather than having asus set the autoclock, I have the following setup

CPU = 3.8ghz @ X19
Vcore = 1.48 (idle at 1.47v, 1.5 on load at 49-50c
CPU/NB voltage = 1.125
NB = 2400mhz
HTT=2400mhz
Ram = 9-10-9-28 1600mhz (CR = T2)

I think that's it. I may try to bump the NB to 2600MHz later, not sure if I'll see a big difference in performance..

That all sounds about right. Put your cpu/nb voltage at 1.225 and take it all the way to 2800.

I've bumped the NB to 2800mhz as well as the voltage on cpu/nb. I'm happy to say that I had prime95 running all night, and it actually stayed on!! Temps were at 50c at 1.52v (not bad I guess)

Not bad at all! Good job. So what clock speed did you settle on?
