I managed to OC my RipjawsZ F3-17000CL9Q-16GBZH to 2400MHz.

Timings:

12-12-12-33-T2

DRAM-Voltage:

1.70000 V

VCCSA-Voltage:

1.25000 V


Is it possible to get them to 2600MHz without lowering my CPU-OC ?

If yes, which Timings etc. could I try ?

[emissary42]

What timings did you try at DDR3-2400 before going with 12-12-12-33 2T?
Also, is a Vdimm of 1.7V really necessary for these kind of timings?

Depending on the chips used in your kit i'd go for DDR3-2400 with something like DDR3-2400 10-12-11-31, 10-12-12-31 or 11-12-11-31 and for testing keep the Vdimm at 1.65V. For DDR3-2600 then start with 11-12-12-31, 11-13-12 or 11-13-13-31. Even if that is stable, the higher memory clock might not be worth it, because of the slower timings (your board will automatically raise several sub-timings as well). So keep an eye on performance between the stable results and safe profiles in UEFI for the good ones.

I tried the following at 1.65V:

- 10-12-12-28-2T
- 10-12-11-28-2T
- 10-11-11-28-2T
- 11-13-12-31-2T
- 11-12-11-31-2T
- 11-11-11-31-2T

All the above got me an endless re-boot-loop without any Bios-Post's etc.

I also tried 11-13-13-35-2T with 1.65V / 1.25V + 1.26875V which didn't work either.

12-13-13-34-T2 and 12-12-12-33-T2 works with 1.7V / 1.25V

12-13-13-34-T2 and 13-13-13-35-T2 also worked for 2200MHz with the same Voltages.

10-12-12-28-T2 worked with 1.65V / 1.25V @2200MHz.

I found most of the settings via Google and that's my first attempt to OC memory at all.

Thanks a lot for your help. I will try your suggestions and report back the results.

If you really need CL12 @ DDR3-2400 and 1.7V then your chances for DDR3-2600 with these modules are very slim

12-14-14-35 2T
12-15-15-35 2T

That is pretty much all what is left in terms of timings, but regardless of the sub-timings needed, DDR3-2133 CL9 should be faster overall.

Ok, I will still try your suggested Timings and have a look, if I'm able to reduce the voltages a bit.

I only OC'ed the CPU to 4200MHz via Bios when I tried the memory-timings and raised the CPU to 4700MHz via AI-Suite-II and I raise the GPU's via OC-Guru-II-Profile.

Ok, I managed to get it stable @2400MHz with the following settings:

- 10-12-11-31-2T
- 1.69V (1.685V was only ~98% stable)
- 1.25V

My 3D-Mark-11 - Score went up from P18208 to P18301

I had no luck with the 2600MHz-Timings, but I didn't play around with the voltages yet and will keep trying.

[supahos]

Those are some very solid timings for 2400 on a cl9 2133 kit With 16 gigs at that speed, there isn't much you can't do. If you just want to make a benchmark magic machine, go with a 2x8gb set of tridents they have the most OC flexibility. However what you have now should chew apart anything you throw at it very quickly. Have you tried 1T? May or may not work, but if it does it will boost benchmarks a tiny bit more

Then try 10-12-11-28 1T next and maybe look into tightening the subs if you really care about points in 3dm.

I will swap the kit over to my old / my wife's rig and have a look how I go there.

When I ran 3D-Mark-11 a few times in a row with the last stable Timings, then I got it a few times that the 3D-Mark.exe crashed.

It's a P8P67 + 2600k @4500MHz (more possible, but not needed) and has at the moment only 1600MHz Corsair Vengeance in it.

I bought today a G.Skill 16G(4*4G) DDR3-2400 Quad Channel [TDX] F3-2400C10Q-16GTX (10-12-12-31 | 1.65V)-Kit, which is only a bit slower then the OC'ed 2133MHz-Kit @2400MHz.

The 2600MHz-Kit's are a bit hard to get in my area, or have to be ordered in from a different state.

If I have time, then I will try out if I can push them a bit further, but it didn't look too good, when I had a few go's @1.65V.

Thanks a lot for Your help and time !

Would like to rep you more then ones if I could.

Thers isnt much difference in chips once you hit 2400 mhz... they can OC about as high as anything else... with 2600k if you got to 2400 stable you gog pretty lucky, would take a tiny miracle to get any higher... glad you manged to get them all up and running well. Both computers should fly

I'm not sure if I just hit the invisible wall with my P8Z77-V - Setup.

I can't push the 3770k further then the 4700MHz either, even that my temps are ok, but I need 1.380 V VCore for Prime95 (max. Heat etc.), but had to increase it to 1.405V for the Battlefield-4-Beta, otherwise the BF4.exe would crash randomly.

That are my max OC-Settings atm:

The new Kit fit's better underneath my radiator. It's still a few mm to tight, but I could squash it a bit easier in.

You got a lretty good cpu, 4.7 is above average i think, you should definitely be happy. Very sold rig you have!

Thanks !

Yeah, I'm quite happy with it.

It could run the BF4-Beta quite well, but it's only average for the badly optimized ARMA-3.

I tinkered again a bit around and squeezed a bit more out of my sys, to justify the money I spend on the new RAM-Kit:

P18456 - 3D-Mark-11-Score

Looks like that I had a few little hick-up's in the background with the new Kit, which disappeared after I increased the VCore to 1.425V.

Had no time for further test's @2600MHz yet.

[TOG-TONSCHUH]

I tried to get them up to 2600MHz, but failed. Seems to be not possible, not even with only 4200MHz CPU-Clock.
