need help with memory settings

[BenD]

i wasn't really paying attention to my memory untill i saw somebody else saying their memory wasn't up to speck,

i have the kingston hyper x blue low profile, it should do up to 1600 MHz,

it was first at 600 until i boosted something up in the bios, setting it to minimal 1300 MHz or arround that, and it just thought well let's do 800 in stead.

any ideas?

Enable the XMP profile in the bios. The RAM automaticallu sets itself to a safe setting. Also if you get your reading from CPU-Z you should double the speed, since it's DDR (Double Data Rate) RAM

I don't know the technical way of saying it. But DDR basically means double that 800 for the actual clock speeds.

What he said^

DDR stands for double data rate so the 1600 is the actual reported speed doubled.

Check in CPU-z (and maybe post a screenshot here), but basically what @marto is saying is that DDR speeds are often showed as halved, because that's how DDR works

EDIT- Just went over my lecture notes, DDR stands for Double Data Rate.

since you all say the same thing, and it's showing in cpu z, i can relax en just watch porn without fearing my pc going to the grave :D thnx , just wondering

Let me chime in here with a related question:

 

What *is* the preferred setting for 1600 DD3?

 

I'm not really into all the finer details of OCing, but I've played around with it on my new rig. I tested OCing both manually (based on my very limited knowledge) and automatically. Used the OC Tuner in the BIOS and Asus AI Suite III's 4-way optimization for the "auto-tune". Although I have to say that I'm somewhat skeptical/cautions when it comes to programs messing around with my BIOS.

 

Here's the setup:

Asus Z87-Plus

i5 4670k, cooled by Corsair H60

2x4 GB Corsair Vengeance 1600 CL9

 

Anyhow: What the automatic OC-solutions seem to try to do is set the RAM to default speed (1333) and raise the CPU-clock a bit further. Automatic tuning resulted in around 4.15 GHz clockspeed with memory running at 1333. I then enabled XMP, which set the memory speed to 1600, and gave me 4.0 GHz. Difference in benchmark-results seem negligible. I ran Passmark's performance-test and got a tad under 4800 (~4790) on both runs.

 

Since I have pretty good airflow in my case and the CPU doesn't seem to break a sweat with the H60 and two fans in push/pull config installed (getting less than 70°C under load on all four cores), I'm fairly certain I could get some more speed out of that i5. But what's the best way of doing that and - more importantly - should I do what the automatic tuners do and go for the lower RAM speed, even though it's rated at 1600?

The auto overclocking feature is probably setting the memory speed to a low value to ensure the highest stable CPU overclock. It is sometime more difficult to overclock the CPU when you have fast RAM. If I were you I would set my RAM to 1600MHz and manually overclock. Not only is a great way to learn about computers, but those auto overclock programs are usually very conservative when it come to voltages.

A safe setting for what?

Thanks! I've been playing around with manual now the last few hours (see my "OCing for dummies"-thread), and I can't seem to get my 4.4 GHz OC stable under 1.3 VCore. 1.28 looked stable but then crashed after about an hour of benchmarking/working/watching porn  educational videos on the web. Went up to 1.29, still no joy. Back to 1.3 now, ran PCMark 7, 3DMark 11 and Passmark's Performance Test and so far it seems stable. *But* after my last changes it seems the BIOS has automatically reset XMP. When I double checked my RAM-speed it was back to 1333 again, even though I hadn't touched the "XMP"-button in the BIOS (have been trying to alter just one parameter per re-boot/OC-attempt).

 

Weird.

 

If it is stable this way, I won't complain though. Consensus seems to be to rather sacrifice RAM-speed than CPU speed, and my bench-results have only decreased very slightly.

 

*shrug*
