TridentX F3-2400C9D-8GTXD & Gigabyte Z77X-UP5 TH OC/Prime95 RS Issues

[Arrow0309]

Should have any real negative effect, might need just a tad more voltage, maybe VCCSA up a tad, say 1.14

Already been at 1.14 of vccsa in the latest round, shall I increase some more?

However i doubt its a temperature problem. My F3-2400C9D-8GTXD barely get warm to the touch, even when overclocked beyond DDR3-2666.

Will your rig complete this exact prime test @ 4.4Ghz and 4.5Ghz with XMP#1 and/or #2 enabled?

Thanks for the info, let's just say I don't wanna even try a lower cpu ckock, I posted before a nice, 4.7ghz, 20 runs of Linx stable @1.27v.
Obviously I wasn't Prime95 stable

Try 1.2, if that flies can drop it 0.01 at a time

[Arrow0309]

Vtt 1.20v and Vccsa 1.20v and it's still not working well, same ~30' later application crash
Tried with dram volt at 1.65 and 1.66

Now what? Increase even more the vtt (is it possible), or the vcore, or test with Xmp's dram volt at 1.680 first?

[Arrow0309]

Just tried with the vtt at 1.225v and vccsa at 1.20v @1.65 dram, same issue:



Going to downvolt the vtt at 1.20 and raise one step further the cpu vcore

Edit:
Just before the windows shut down I even got a 1e bsod (which is the vcore) so I just raised two steps, from 1.25 to 1.26v and set the vtt/imc at 1.20/1.14
Hope is gonna work

[Arrow0309]

Victory! it was the vcore
One hour is already passed

And three last questions, are these voltages (vtt-1.20, vccsa-1.14, dram1.65) safe for a daily?
I'm gonna try first a small tweak, like let's say CR1T and tRAS 28 or 25, should I leave the Xmp or just set everything manually?

And once I decided I'm still stable, what should I start trying to decrease first, the vtt or the vccsa?

[GSKILL TECH]

Glad to hear!

Those voltages are just fine for daily. I doubt you can get them much lower while maintaining stability.

XMP or manual is fine, settings are the same.

If the system is perfectly, just leave it as is, unless you just want to tweak it for fun.

Thank you

Nailed it

Save yourself a bios profile with your settings on an usb-stick. Even when something goes wrong, you can always go back to that and start over again. You can probably drop VCCSA quite bit, but lowering VTT/VCCIO might have big impact on stability --> small steps recommended.

Command Rate 2T --> 1T has a bigger impact on performance. So i would focus on that first.

Happy tweaking!

[Arrow0309]

Thank you all for all of the info's, help and support
I'll definitely save the bios profile and start with the 1T first
It was nice having this discussion with you
Se ya

[Tradesman]

Keep us updated and keep your eye out for BIOS updates, think they should be working on that, they might come up w/ something that offers a little lower voltage

[Arrow0309]

Here I am again, took me a while but I finally succeed (hope so) finding my improved yet prime95 stable settings for my cpu / ram

So I only raised the cpu vcore by 0.01v but lowered the Vtt down to 1.15, the cpu pll down to 1.7 and nicely, the Imc (vccsa) to 0.925 (default)
And, of course, Xmp @ 1.65v and 1T



One hour and half stable
I know, I should go on testing for some more hours too but as far as is concerned it's ok for me right now!

[Tradesman]

Sounds good, keep in touch

[Arrow0309]

There's still something wrong with my system and I don't know anymore if it's the memory or the imc not 100% ok
I've had a couple of (vcore related) bsod's, first one 0x3B about a week ago and then, the day before yesterday one 0x1E
They both happened at the very end of the day, during the windows shotdown
I had to raise the vcore but I didn't, wanted to test some more

Now I was playing some intensive Metro Last Light and, after a couple of hours or so I got a bad, 0x124 bsod crash
So I only tried to increase the vccsa from its default to 1.0v and just after the windows start up gave me an 0xF4 bsod this time, which I really don't get it

Supposing that I'm still having this settings (as above):

4.6ghz OC, HT, Eist only
XMP Profile 1 @ CR:1T
Vcore: 1.27v fixed (LLC Turbo)
Vtt: 1.15v
Vccsa: 0.925v (auto)
Cpu Pll: 1.70v
Dram: 1.65v

What do you suggest me to increase?

Edit:
Ok, so I slightly bumped the vcore by 0.005v and then tested with Linx, Problem size: 27000, Run: 25
Seems stable enough to me

Let's try VTT at 1.2

[Arrow0309]

Ok, thanks

[Tradesman]

Raise PLL 1.75 to 1.8....may take VTT 1.2 and can lower is stable while maintaining stability
