RAM Performance

sygnus21 · 11 Jul 2011

Seekermeister it seems to me that the issue is with the motherboard and not the RAM, not the CPU. I don't think you're going to get anywhere until you address or elininate the motherboard as trying to figure out what's going on without doing that is fruitless. I know you keep fighting that thought but that's honestly where you need to start. Sorry

I have not yet posted on the ASRock forum, because I don't think that it is an ASRock problem, nor do I think that it is a Patriot problem. Yet, I probably will, because I will take an answer wherever I can get it.

Just trying to help.

BTW.....

An AMD board will not spec the memory any higher than 1333 9-9-9-24. None of them because that is set by the memory controller on the CPU. To run it faster you have to manipulate the timings and OC the FSB to increase the frequency. That has been an issue with AMD chips for a long time. That is why so many people were happy about the AM3+ chips. They have natural memory controller up to 1866. When you go in to manually set your timings, check. My AMD board you had to set the timings for each module. I have no earthly idea why, but that's the way it worked.

Okay, so if 1333 is max without timing otherwise, what do I change to get to 1600? I decided to change the Command Rate from 2T to 1T in the BIOS, but found that Overdrive still showed it set to 2T. I reset it in Overdrive, and it seems now to keep that setting. This seems to indicate what I said previously, that the BIOS settings are being ignored. I would try to reset the frequency in Overdrive, but the window for that is grayed out.

EDIT: I had thought that the only reason to buy a motherboard with a 990 chipset was for compatibility with Bull Dozer processor, and had no idea about this timing issue. Had I understood that, I would have spent more on the motherboard.

Like I said kast night about the 990 chipset, I don't know how it interacts with the AM3 chips. If you had a 990 board, you would still have the same memory controller because it is on the chip. How the new boards deal with that I don't know. The new chips' memory controller are on the chip also, but they allow up to 1866 memory.

The guide I used to increase my ram freq. is the post I posted last night from g skill. All AMD boards work the same way because they have to because of the limitations put on them by the CPU memory controller. I didn't have a black chip, but I believe your FSB is 200. If you are running at 1333 you have to increase the FSB to 240. That will raise your ram speed to 1600. Then run memtest and prime95, to make sure you are stable. that's the only way I know to do it.

It will also overclock your CPU. You can control how much OC by the multiplier.

Okay, I guess that I misunderstood, and it wasn't the motherboard chip that you were speaking of, but that of the CPU. I'm curious, had I chosen the 1100T, rather than the 1090T, would I still have this problem?

essenbe · 11 Jul 2011

Yes. It has the same memory controller on the CPU as do all AM3 chips. That is one of the things people are looking forward to in Bulldozer, it will have a different memory controller allowing up to 1866.

essenbe,

...I believe your FSB is 200. If you are running at 1333 you have to increase the FSB to 240. That will raise your ram speed to 1600.

The only thing I found in the BIOS that appears to be the FSB speed is called HT Bus Speed. If that is the right one, then it still won't work as you described, because the settings double on each step, after 200 comes 400. 400 sounds like a big change to make...am I looking in the right place?

essenbe · 11 Jul 2011

No. It should be around the multiplier. I don't remember what it's called, but it is called different things. It controlls your CPU speed. FSB X Multiplier = CPU speed. Your multiplier should be around 16-16.5. It should be called the multiplier. I just don't know what your FSB is called.

Should be a voltage like 200Mhz

Should look something like this:

essenbe · 11 Jul 2011

On my board it was in the section called "Cell Menu" it was under 'adjust CPU FSB frequency'. It will be in the section of your bios for overclocking or for advanced users. It should be in your manual.
