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.

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?

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.

I dont have one called TRRSR...

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...

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?

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!
