X79 MEMORY OC GUIDE (4 Different IC) --- G.SkILL + ASUS Rampage IV Extreme

the ripjawsz 2400 cl9-11 or the tridentx 2600c10 or tridentx 2666cl11

and 4x2GB (or 2x2GB)?

thanks :)

they are all 4 x 2 or 4 x 4 , 4gb modules.

finding 2x2 is not easy anymore but best on x79 is psc like PIS series, some old trident stuff, some ripjaws 16000 and the latest is ripjawsz 2400 8-11 or ripjawsx 2200 7-11-7
if tRP is same as Cas so probabily they are good PSC , if tRP is higher they are hynix or bad psc.
you can go with some bbse kit too like 2133 8-9-8

I search 2gb module (4x2gb or 2x2gb) kit 8GB and not 16GB

ok, if 8-9-8, probability PSC
if 8-9-9, probability hynix or bad PSC, right?

is 10-12-10 for Corsair CMGTX8, but it's Hynix ICs

Thanks ;)

I'm curious as to why BBSE is good on X79 but not BASE Hyper. Is it just tRCD? Wouldn't loosening tRCD enable Hypers to clock just as well as BBSE?

no caz hypers doesn't like high tRCD

Hmm, didn't know that.

This MB sets in Auto VTT 1,370 and VCCSA almost at 1,4V :confused: It's when I choose DDR2400 MHz (10-11-11-30-1T @ 1,65V). VCORE ~1.45(6), 4.9 GHz, BCLK 100. I've got Geil Evo Two GET316GB2400C10QC (4x4 GB).

Don't you think it's too much? I can only say, that with VTT 1,3V and VCCSA 1,35V system unstable during Prime95 (Blend). Only at Auto (so high voltages) I was able to run Prime95 Blend for more than 15 hs (after that I stopped the test). I have not tried intermediate voltages.

But in X.M.P. I see 2T and I like 1T so set it.

that's right?

the G.skill 2133 9-11-10 have hynix or bad PSC, right?

thanks ;)

Is what the Dominator GT 2000 8-9-8 (CMT) with PSC ICs normally, are stable at 2400 C8 and 1.65v on X79 (Asus RIVE)
I saw on another topic that was stable but on S1156, I believe

Thanks ;)

you're probably on ln2 mode. use with caution. actually don't apply those voltages.

the 2133 8-9-8 are bbse and some hyper but not easy to find
9-11-10 shoud be hynix as they are 4gb sticks. i never saw any 4gb psc module.

it's 2gb modules (4x2gb)

thanks ;)

I don't think so.

I have this Dominator GT 2000 7-8-7 (CMG) Elpida Hypers that can run 3DMark Vantage at 2400 9-10-9-28 but only with 1,78v+. And they are not Pi 32M stable, actually the system turns off when the test begins.

Can you PM me the link of this topic you saw?

Dominator GT 2000 8-9-8 have PSC ICs, not Elpida

I didn't know about this 1.5v RAMs.

Anyway, with +0.15v I can almost do the same.... 2400 9-9-9 @ 1.80v

>you're probably on ln2 mode. use with caution. actually don't apply those voltages.
No, I'm not. But it's too late :D With this voltages and + 1,5V VCORE, I'v started LinX for 1 hr. Hottest core was 91C (and I saw a red LOG). I was a little drunk and just tested my new CPU :( It was few days ago, but yesterday it was a Prime95 Blend test (with normal for me (~1,46V) VCORE).

But now it's OK. VTT - 1,2V and VCCSA - 1,23V. Prime 95 Blend 15 hrs and LinX 1 hr. I don't know why I had a problems. Maybe 1,65V on RAM in BIOS it's not enough (MB sets a little higher, as me now, about 1,67V). Or maybe VTT and VCCSA was it that positions, that I had problems (not too low and not too high) or it was a bad delta, I just don't know :shakes:

Thx for your reply.

But guys from ROG says that "Secondary VTT does not, however try to maintain at most a 300mv delta for stability. 1.40v is fine on these CPUs" :D

The CMT4GX3M3A2000C8 ver. 7.1 (8-9-8-24) are also good in OC that CMT6GX3M3A2000C8 ver. 7.1A (8-9-8-24)?

Thanks :)

I tested the Dominator GT (CMT4GX3M2A2000C8) 2000 8-9-8-24, ver. 7.1 (PSC IC)

At 2400 9-11-10-28 1T is not stable with HyperPI 32M,
What is the best setting to be stable h24?

I tried with all sub-timings on AUTO, PSC profile but without success (the tRFC is 120 or 128)
I can test with 143 or 147?

Thank you

PS: I saw the same Dominator GT (but CMT6GX3M3A2000C8, ver 7.1A) stable h24 at 9-11-10-28

Hmmm... 2000 8-9-8 I would have thought to be BBSE. For 2400 with PSC, try 10-12-10 and work your way down. It's possible that 9-11-9 may take more than 1.65V since 2000 8-9-8 isn't a very high bin for PSC (2000 7-9-7 or 6-9-6 would be higher).

This is the PSC, take some kit to 1.65v 2400 C9 (and C8 from one topic where I put the link above)

What kit PSC are 2000 7-9-7?

Thanks

we have GSKILL Flare 2000 7-9-7 4 X 2GB

Not avalaible :(

Thanks

The PSC profile, Hynix, etc... adapts with the frequency, or it is the same for all frequency?

Thanks

Please :D

And I tested the kit Dominator GT CMT6GX3M3A2000C8 (8-9-8-24, PSC ICs) of a friend on a Rampage Extreme 4 (only 2x2GB)

For my friend, is stable at 2400 9-11-10-28 1T 1.65v (OCCT and LinX)
But for me it is not stable with Hyper PI 32M with the same timings/sub-timings (HyperPi is more violent than LinX?)

I do not use the airflow or fans, is what it is because of this?
Or what is the controller of my CPU is bad compared to his

Thanks ;)
