How do I get gskill DDR3 1600 eco 7-8-7-24-2N to CL6

post #1 of 7
Thread Starter 
Newegg lists them as 7-8-7-24-2N and they are 1.35V, I don't know where the 2N setting is.

On the SPD tab of CPUz, it recommends, or says they are

XMP-1600
7-8-7-24-40-2T, the Bios uses 1T on [auto]

So in the Bios I set them to 7-8-7-20-28-1T, and have used them in stable OCs, at various RAM speeds and volts as high as 1.47500V


But with everything back to stock, except still using my x3 unlocked, I don't know how to get them to some form of CL 6, nothing has worked yet, and there is a load of numbers in the DRAM config page that can be changed, and I don't know if tighter timing needs more volts or not.

And the "ram with the RAM shades" guy uses the same at 6-8-6-20-24-1T, when I tried that, it hasn't worked yet.

RAM with the RAM shades!?
Also, it's not very hard at all.
Use around 1.5V DRAM voltage (you're safe up to 1.65V, nominally ECOs stop scaling with voltage at 1.6V)
The C2 revision processor (Phenom II x3) might make it a bit hard, you may need to add a bit more DRAM voltage than usual. You also may need to reduce your RAM speed a bit (i.e. from 1686 back to 1600) to reach 6-8-6. I haven't seen a single kit that doesn't reach 6-8-6 yet.

Yes, voltage does affect overclockability. I'd bump it to around 1.5v and try the 6-8-6-20-1T Configuration. If it doesn't work, bump another notch of voltage.

Ok I'm going to try that right now. Thanks to both.

You going to need 1.6v for 6-8-6-20-24-1T @ 1600+.

Ok so with stock everything and the great bios which kind of points at whats not working by putting some timing settings back to [auto] after a failed attempt

@1600 6-8-6-24-33-1T, 24-33-1T is the [auto] choice, I got 1.52500V to post, but without the x4

So I put the CPU/NB volts from stock 1.2 to 1.3V, and now I'm back to a x4 40, but windows didn't fully start

Put it 1.375V, which it was at for some stable OCs, and windows got a bit further.

Then I put the RAM to 1.55V, taking leaps of faith with the volts, (I'll be down in the dumps if I have to get out my P4 again until next payday...)

So at

1600 6-8-6-24-33-1T @1.55V and 2000 CPU/NB @ 1.375V, and a x4 40

I'm back in time for the alex jones show.

So next step is to try some breif p95, and go from there for now with this timings and see what the CPU can do.


In general which is safer and needs less CPU/NB volts

higher FSB x lower mutli = Y MHz

lower FSB x higher multi = Y MHz

For now I don't want to go over my highest of 1.375V, and see what works up to that.

So in general, will I also need more volts overall on the CPU/NB to run lower timings at some given speed?

I think thats why folks say the C2 chips are more limited when they are a x4 as opposed to what they might do as an x3
