SOLVED RAM Timings?

[Twisted4000]

Hello, I've recently made a thread here talking about what timings I should set RAM at when it's overclocked. Well I'm curious now, I don't know if my setup is being weird or if it's supposed to actually be this way but here goes.

The RAM models are G.Skill Ripjaw, 4GB DDR3 each (I have two so it's a total if 8GB). http://www.newegg.com/Product/Product.aspx?Item=N82E16820231310

When I set everything on auto, have nothing overclocked, my RAM's speed shows up as 1066MHz, even though the manufacturer says it's 1333MHz RAM, and in the motherboard, you can see one number say 1333, but next to it, there's a number that says 1066. Is 1333 like the standard setting or something? And someone told me that it was at 1066 because my core clock speed for my CPU was at 266.

The manufacturer also says the timing should be 9-9-9-24. When I keep everything on auto, that's what it says. However, when I go into Speccy in Windows, it reads 7-7-7-20. Is this right, is this a good thing? Or is it improperly configured?

When I keep the RAM timings on manual however, it shows up as 9-9-9-24 in Speccy. Is Speccy just picking it up incorrectly when I keep it on auto or is that literally how it should be?

Right now I just have everything on auto, and in the motherboard, as you can see in one of the pictures, it's showing up as 9-9-9-24, but in Speccy it's saying 7-7-7-20.

The number on the left on BIOS is what the standard SPD profile lists the ram speed as (1333). The setting on the right is what the BIOS has set the RAM to run at (1066).

So by the SPD profile, it is rated to run at 1333 9-9-9-24. The BIOS states it is setting it to run at 1066 9-9-9-24.

I don't know if speccy is accurate with memory timings. Please use CPU-Z, as its the utility that is more widely accepted in the enthusiast scene, and we are certain it isn't buggy because its used widely by our crowd. CPU-Z will tell you if speccy is getting a wrong reading, or if thats really what the ram is running at.

I would set it manually to the rated settings.

Thank you very much, makes much more sense now.

And I figured Speccy was inaccurate, lol.

Alright, well I got CPU-Z, and it's saying the same thing about the timings.

7-7-7-20 it looks like.

I want to know if it's better to have the timings set like this, or to go to 9-9-9-24? Plus I'm curious why the BIOS says it's at 9-9-9-24 when both Speccy and CPU-Z are picking it up as 7-7-7-20.

 

[I.M.O.G.]

Ok, so BIOS is saying SPD is 1333 9-9-9-24, but apparently SPD for 1066 is 7-7-7-20... When running at lower frequency, the memory can run tighter timings. That is normal.

I'd increase the memory frequency in BIOS, and that should loosen timings to 9-9-9-24 and you will be running right at the RAMs rated settings.

Alright, so is it best do to do that, will it be more stable that way, or?

 

[I.M.O.G.]

It will be equally stable. The RAM is rated for 1066 7-7-7-20 or 1333 9-9-9-24. You'll benefit more from the bandwidth of 1333 than the tighter latencies of 1066.

I would do that, but I can't increase the frequency anymore without increasing the processor clock, considering it's at 266x4.00D. Unless, there is another way...?

 

[I.M.O.G.]

You can change it with System Memory Multiplier. It is currently set to auto, and you can change that to increase your memory frequency without changing your bclk.

Right, but even when I manually set it, the highest is 4.00D, and when I set it at that, I get the same 1066.

Oh, ya. I don't hardly know crap about overclocking C2Q's. Sorry.

You'd have to bring your bclk up to 333mhz to get to 1333 on the memory then. If that's too much of an overclock on the CPU frequency (333 x 9 = 3GHz) , you'd want to drop your CPU multiplier a notch to 7, 7.5, or 8 (I don't even know if 7.5 is an option). If you dropped your CPU multi to 7, that would give you 2.33GHz which would be below stock on the CPU, which isn't great. If you can do 7.5, that would give you just above stock. If you do 8 that would give you a nice 2.66GHz overclock.

Alright, thanks, I'll go ahead and do that.
