**WANT 8GB 2400MHz FOR AS LITTLE AS £59.99 Inc. VAT? - THEN CHECK THIS THREAD OUT!!** (MV-3V4G3D/US)

Bios bug mate sadly.

I have had 2800+ mhz Trident X tuned profiles lost that took literally hours.

They know about it and it will be fixed.

oh darn - not the answer I was expecting but thanks - glad it wasn't me then

do you know what triggers it ? is it when you get the "overclocked fail" message or random ? is it new to 1309 ?

last bios took a few months to come out - lets hope a hotfix is out sooner than that - its not so bad with other mobos, but on the Genes you have so many settings over so many pages its a pain to go backto your settings - if you ever can !

I on your 2800 Trident tuned profiles

thanks

It seems to be at random. Its been with all the Bios upto press as far as I am aware. I am still on an early release Bios. Once I have stability and features thats it for updating for me.

Good effort although 18 is no better than 21 TRAS on those settings. TRFC 88

i just put them as low as they would go without crashing

what about trfc 88?

 

[HankScorpio]

For 8 CAS @ 2000MHz+ you need to really push the voltage on the DRAM. (SB-E) I need 1.625v @ 2000MHZ 8,9,9,21

Cheers. Just tried this, put dram up to 1.625 for 8,9,9,21 @ 2000Mhz and it worked. Question is is this increase of volts, from 1.45v to (currently stressing 1.575v) worth it for a decrease of cas from 9 to 8 ?

Edit, seems stable at 1.6v, but prime95+superpi give me errors at 1.575v

 

[8 Pack]

Leave it at 1.6 then. Cas is the most important value when tuning RAM.

TRFC 88 is great yes.

Leave at CAS8 1.6v, it'll do no harm.

oh ok cool

Guys (mainly 8 Pack), is there another term for LB (Latency Boundary), it's not labelled in the Sabertooth X79 BIOS, it could just be that it doesn't exist in there..

 

[8 Pack]

Latency Boundary is the term this setting was named by the ROG Bios engineer who came up with the setting. Basically the setting sets the third timings for the user with settings that are known to work well with each other in terms of perf and stability.

The lower the number the higher performance from the memory. Only very high binned kits with volts can do LB 1 or 2. Most end up around 9-11 for stability, speed and perf 24/7.

This is a ROG only thing though no other line of boards have it.

Ok cool, cheers dude. I have manually set thirds anyway.

2133MHz 10-10-10-28 1N at 1.4V here.

Does exactly what OCUK claim, amazing memory.

In case fellow P67 (as in sig) board owners are interested:

I was slightly quick off the mark - hadn't thoroughly tested, wasn't quite stable. My bad.

After reading this thread fully have now settled on trying to get 9-10-10-21 2133 stable. Nearly there - currently using 1.55V DRAM and 1.1V VCCIO.

 

[Yaayuh!]

Currently sitting at 2333MHz @ 1.55v 10,11,11,21,1T with TRFC 96. Waiting for some secondary and third timings off of 8 Pack to get them tuned.
My CPU doesn't like 100 BLCK when overclocking so i'm using the 125 strap which doesn't give me a 2400MHz option. So hopefully i can get 2333MHz tight.

 

[8 Pack]

It gives you 2444 at 131 man!!!! Whack it up!!!

I will try get some stuff to you later today on that bud.

I will be increasing the BCLK but i'm CPU bottlenecked really, i lost in the silicon lottery. 1.42v required for 4.6GHz and i'm on air...

8 Pack - quick question please as you clearly know what you're talking about!

As above, I'm currently running 9-10-10-21 2133. Is 21 the best tRAS to be running with this memory? Any point in trying for tighter?

Thanks

 

[wazza300]

you can try lower than 21,but i doubt youd gain much or be stable,only way to know is test and test read/write/copy figures ect

EDIT: tightening your trfc will help too

21 is the lowest for stability and perf. Perf actually takes a hit lower than this. 21 is great at 2133.

Rossi gonna put some samsung in X79 for you mate. Just give me chance!!!

 

[BrianB]

I think you are lucky to get 9-10-10-21, I couldn't get mine that low, 9-11-11-21 for me. TRFC 96. I'm wondering about the other timings if it's possible to lower them. I am at 1.5V 2133.
