RAM OC guidance.

Hi 8Pack,

My new machine seems pretty stable at the moment. Thanks for all your advice.

I'm running 4.625 125bclk with 125 strap.

I've set my DRAM timings as on the packet, and left everything else auto. This gives me an option for 2000 or 2333 for the speed of the RAM. I've elected 2000 initially.

I tried to set the RAM to 2333, clock gen to 20uf and DRAM Voltage (CHA,b,c,d) to 1.6v and windows will not load (BSOD drive_irq_not less than equal blah blah).

If i set the DRAM voltage to Auto all is fine.

The ram (teamgroup 16GB 4x4 LV 2133) suggests 1.5-1.6v on the packet. But I presume the mobo is giving it more on Voltage to get it to work.

What should my next steps be? Leave it on auto and be happy? Or try and give it more juice. Should I loosen the timings from CAS9-11-11-28.

9-11-11-28 looks like Samsun IC to me. They will scale to 1.75v easy. 2333mhz should be an a very reachable target.

Initially go 9-12-12-25 get em stable mode 1. Then go 9-12-11 21 1T. Then dial the seconds down to 5-auto 128-12-6-26-6-8, Try the last number at 7 if you can for perf boost.

VCCSA tune upto 1.15v for IMC and VTT the same.

Cheers.

So I'll put the dram voltage to 1.65v, set to 2333 with 9-12-12-25 timings with 1T. Already set to mode 1 from our previous conversations.

No clue what dial the seconds down means. Can you elaborate for my setup.

What tool is best for testing Ram?

8 Pack · 14 May 2013 at 15:12

AIDA 64 for performance. Use memtest and prime blend / using it for stability.

The secondary timings set the ones I gave you down the bios.

Skynet5 · 14 May 2013 at 16:21

Here are my settings.

I know it says 1.5, but that is the old value. The yellow value is what was saved and unreadable in the picture...it says 1.65v

Prime fails pretty quickly here.

More DRAM Voltage? Or should I look at my timings. Haven't played with setting the secondary timings yet.

Whats TRRSR set at in the thirds?? Try memtest first never mind prime.

Skynet5 · 14 May 2013 at 16:49

I dont have one called TRRSR...

8 Pack · 14 May 2013 at 16:52

tRWSR sorry. Ok in the thirds Back out tRWSR to 8 and tRWDR to 8 and test again.

Also you are doing this with no OC on CPU yeah???

Ummm no. I have my 3820 clocked to 4.6 125x37...

8 Pack · 14 May 2013 at 16:57

So you don't know if its IMC or RAM or what. You need to do it separate then put together the results.

Skynet5 · 14 May 2013 at 17:04

Now that would make sense wouldn't it. Ok. I'll remove my OC and try again, but I've run out of time for today. My OC is what gives these dividers though (2000, 2333) does that not matter so much? Just work out the memory timings, ball park freq and voltage first then OC CPU then pick the closet divider?

I think, if they don't ready, ocUK should run workshops on this. Be a cool way to get idiots like me on the straight and narrow.

test at 4ghz thats near enough. Slight bump in Vcore all else stock. IMC 1.05, VTT 1.1.

your referring to VTT CPU Voltage correct? What setting is the IMC...integrated memory contoller? what setting is that in the rampage bios?

8 Pack · 14 May 2013 at 22:06

VCCSA is IMC volts.

scotsdragon · 16 May 2013 at 13:39

They do run a workshop your in a master class just now with 8 pack lol your doing fine

8 Pack · 16 May 2013 at 13:52

I will be doing some demo's of all kinds of clocking at some stage very soon to coincide with the launch of my systems. Some forum members will be invited to them and we can hit some RAM clocking hard then.

Skynet5 · 16 May 2013 at 18:30

Well I'm nowhere near as active as others here, nor have contributed as much as them. But...if there was a space please keep me in mind, as I'd love to come and see the demo.... if you don't ask you don't get!

As an aside, I've stopped focusing on RAM OC and making sure I have a better understanding of my CPU OC. So I'm about to update the other thread!
